Various objects/components/elements in the ultrasonic blade energyoutput control system 100 will be further described below.

Thecutting head 131 is an executing component of theultrasonic blade 130, and particularly, surgical operations including, but not limited to, punching, back cutting, clamping cutting, or coagulation can be executed through thecutting head 131. Cutting-head 131 is brought into contact with the patient's tissue during the performance of the surgical procedure.

Thecutting head 131 includes a first cutting head assembly and a second cutting head assembly, which can move relatively/rotate relatively, such as a shaft, so that the cutting head state of the cutting head for performing the surgical operation changes between a first opened cutting head state and a second closed cutting head state, wherein the first cutting head state is an opened state, and the second cutting head state is a closed state. The tool bit state in the embodiment of the application only defines two states: an open state and a closed state.

Shankassembly 132 forcoupling transducer 120 andtool tip 131.

Thesensor 133 is configured to obtain a sensing signal according to a head state of thehead 131. The number of thesensors 133 may be one or more.Sensor 133 may be disposed intool shank assembly 132 and/or intool tip 131, and the location ofsensor 133 is not particularly limited.

Sensor 133 may be any contact sensor, such as a pressure sensor, and accordingly,sensor 133 may be disposed intool shank assembly 132 and may also be disposed intool tip 131, andsensor 133 may also be any proximity sensor, such as a distance measuring proximity sensor, and accordingly,sensor 133 may be disposed intool tip 131. Thesensor 133 may be any electrical sensor, such as a hall sensor, or any mechanical sensor, such as a switch sensor. Thesensor 133 is not particularly limited, and is specifically what sensor is.

The corresponding function is unchanged regardless of where thesensor 133 is disposed, and regardless of whichsensor 133 is specifically the sensor.

Transducer 120 converts the received electrical energy into kinetic energy and transfers the kinetic energy totool tip 131 throughtool shank assembly 132. Specifically, the piezoelectric ceramic in thetransducer 120 converts electrical energy into mechanical vibration energy, which is amplified and transmitted to thecutter head 131 through the horn.

And the measuringunit 140 is configured to acquire the sensing signal of thesensor 133 and the electrical parameter of the ultrasonic blade energyoutput control system 100 during operation, and send the sensing signal and the electrical parameter to theultrasonic host 110. Themeasurement unit 140 includes a circuit therein. In one embodiment, themeasurement unit 140 is integrated into theultrasound host 110 as part of theultrasound host 110; in another embodiment, themeasurement unit 140 may also be integrated in theultrasonic blade 130 as part of theultrasonic blade 130. Wherever themeasurement unit 140 is integrated, its corresponding function is unchanged, i.e. sensing signals from thesensor 133 and electrical parameters of the ultrasonic blade energyoutput control system 100 during operation are acquired and sent to components/elements/objects capable of processing their data, such as thecontroller 111.

Theultrasonic host 110 is connected with thetransducer 120, and theultrasonic host 110 is configured to provide electrical energy to thetransducer 120, acquire a sensing signal and/or an electrical parameter when theultrasonic blade 130 is excited and/or after theultrasonic blade 130 is excited, and control thetransducer 120 to provide corresponding kinetic energy according to the sensing signal and/or the electrical parameter so as to control the energy output of theultrasonic blade 130, that is, when theultrasonic blade 130 performs a surgical operation, theultrasonic host 110 determines the energy delivered to theultrasonic blade 130 according to the sensing signal and/or the electrical parameter so as to control the energy output of theultrasonic blade 130.

In one embodiment, the ultrasonicmain unit 110 controls the supply of the corresponding electric energy to thetransducer 120 according to the sensing signal and/or the electric parameter when theultrasonic blade 130 is activated and/or after theultrasonic blade 130 is activated, i.e., the adjustable electric energy drives thetransducer 120 to supply the corresponding kinetic energy through the corresponding electric energy, so as to control the energy output of theultrasonic blade 130.

Correspondingly, the corresponding voltage (adjustable voltage), the corresponding current (adjustable current) or the corresponding power (adjustable power) is controlled to be provided to thetransducer 120 by theultrasonic host 110, so as to control thetransducer 120 to provide the kinetic energy corresponding to the corresponding voltage, the corresponding current or the corresponding power, and thus, to control the energy output of theultrasonic blade 130. That is, thetransducer 120 is controlled to provide corresponding kinetic energy by providing different voltages, different currents and different powers of current to thetransducer 120, so as to control the energy output of theultrasonic blade 130, and the adjustment of thetransducer 120 to provide corresponding kinetic energy can be performed by different voltages, different currents or different powers, which will not be described repeatedly.

In an embodiment, theultrasonic host 110 provides fixed power to thetransducer 120, and theultrasonic host 110 controls thetransducer 120 according to the sensing signal and/or the electrical parameter, so that thetransducer 120 processes the fixed power to adjust the kinetic energy provided by thetransducer 120, thereby controlling the power output of theultrasonic blade 130, in this embodiment, thetransducer 120 has a microchip, which is not described in more detail in this embodiment.

The drivingunit 112 of theultrasound host 110 is configured to provide power to thetransducer 120 and drive thetransducer 120 to operate. Thecontroller 111 is configured to acquire the sensing signal and/or the electrical parameter when theultrasonic blade 130 is activated and/or after theultrasonic blade 130 is activated, and control the drivingunit 112 to provide the corresponding electrical energy to thetransducer 120 according to the sensing signal and/or the electrical parameter, so that thetransducer 120 provides the corresponding kinetic energy to control the energy output of theultrasonic blade 130, that is, thecontroller 111 determines the energy delivered to theultrasonic blade 130 according to the sensing signal and/or the electrical parameter when theultrasonic blade 130 performs a surgical operation to control the energy output of theultrasonic blade 130.

The working principle of theultrasonic blade 130 is further described below: the ultrasonicmain machine 110 provides high-frequency electric energy to be transmitted to thetransducer 120, the piezoelectric ceramic in thetransducer 120 converts the electric energy into mechanical vibration energy (the following kinetic energy includes the mechanical vibration energy), the mechanical vibration is amplified and transmitted to thecutter head 131 through the amplitude transformer, thecutter head 131 generates vibration of about 55.5kHz, the vibration amplitude is about 50-100 mu m, the vibratingcutter head 131 is in contact with the tissue of a patient, protein hydrogen bonds of the tissue are broken due to mechanical impact, and meanwhile, due to heat generation and temperature rise, tissue protein cells are finally denatured to form viscous coagula, so that the cutting or coagulation purpose is achieved.

The medical personnel may use theultrasonic blade 130 to cut or occlude tissue during a surgical procedure using various surgical procedures (also referred to as surgical procedures) including, but not limited to, perforation, back-cutting, clamping, cutting, or occluding. The following will refer to the surgical procedure therein.

In one embodiment, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to determine a tool-tip state of the tool-tip 131 according to the sensing signal, and control thetransducer 120 to provide corresponding kinetic energy according to the tool-tip state to control the energy output of theultrasonic blade 130. For example, thecontroller 111 controls the drivingunit 112 to provide corresponding electrical energy to thetransducer 120 according to the state of the tool bit, so that thetransducer 120 provides corresponding kinetic energy matched with the electrical energy to control the energy output of theultrasonic blade 130. In this embodiment, the sense signal is used only to determine the state of the blade, and thecontroller 111 controls the kinetic energy delivered to thetransducer 120 based on the state of the blade to adjust the energy output of theultrasonic blade 130 to improve the quality of the procedure.

The tool bit state of thetool bit 131 includes an open state and a closed state.

In one use scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to provide a fixed kinetic energy to control theultrasonic blade 130 to output a fixed energy when the sensing signal indicates that the tool bit is in the open state. For example, when thecontroller 111 determines that the cutter head state is the open state according to the sensing signal, the drivingunit 112 is controlled to supply a preset power, which is determined by any one or more of a preset voltage, a preset current, or a preset power, to thetransducer 120, so that thetransducer 120 supplies a kinetic energy matching the preset voltage, the preset current, or the preset power to control theultrasonic blade 130 to output a fixed energy.

The preset voltage is a certain fixed voltage, the preset current is a certain fixed current, and the preset power is a certain fixed power, and the preset voltage, the preset current, or the preset power is a voltage, a current, or a power corresponding to the normal operation of the ultrasonic blade energyoutput control system 100, so that thetransducer 120 outputs kinetic energy with a fixed amplitude (e.g., a preset amplitude), which will not be described repeatedly below.

Wherein, when thesensor 133 is a proximity sensor, a pressure sensor, a hall sensor or a switch sensor, the determining of the cutter head state of thecutter head 131 according to the sensing signal includes: if the sensing signal changes, the determined state of the cuttinghead 131 is an open state, and if the sensing signal does not change, the determined state of the cuttinghead 131 is a closed state.

For example, when thesensor 133 is a proximity sensor, the proximity sensor is not triggered when thecutter head 131 is in the off state, and the proximity sensor does not sense a signal or does not change any signal, and the proximity sensor can detect and generate a sensing signal during the opening of thecutter head 131, so that the sensing signal changes.

For example, when thesensor 133 is an on-off sensor, the cuttinghead 131 of theultrasonic blade 130 is turned on according to the pressure signal when the pressure signal is detected on the pressure sensor, and when the cutting head of theultrasonic blade 130 is in the off state, the on-off sensor does not need to be triggered.

Hereinafter, please refer to the description of this section for determining the state of the cutter head according to the sensing signal, which will not be described in detail later.

In one embodiment, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to determine a surgical procedure currently being performed by theultrasonic blade 130 based on the sensed signal, or based on the sensed signal and the electrical parameter, and to control the energy delivered to theultrasonic blade 130 based on the surgical procedure currently being performed by theultrasonic blade 130. The sensing signal in this embodiment may be used to determine the surgical procedure currently being performed.

In one embodiment, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to determine a blade status of theblade 131 according to the sensing signal, determine a surgical operation currently performed by theultrasonic blade 130 according to the blade status, or determine a surgical operation currently performed by theultrasonic blade 130 according to the blade status and the electrical parameter, and control thetransducer 120 to provide corresponding kinetic energy according to the blade status and the surgical operation currently performed by theultrasonic blade 130, that is, control the energy delivered to theultrasonic blade 130 according to the blade status and the surgical operation currently performed by theultrasonic blade 130, so as to control the energy output of theultrasonic blade 130. In this embodiment, the sensing signal is only used to determine the status of the scalpel head, after the status of the scalpel head is determined, the current surgical operation performed by theultrasonic scalpel 130 is determined according to the status of the scalpel head, or the status of the scalpel head and the electrical parameter, and finally the electrical energy provided by thetransducer 120 is controlled according to the status of the scalpel head and the current surgical operation performed by theultrasonic scalpel 130, so as to control theultrasonic scalpel 130 to output corresponding energy in the surgical operations performed in different scalpel head statuses, thereby improving the surgical quality.

Determining the current surgical operation being performed by theultrasonic blade 130 according to the blade head state includes: if the cutter head state is identified to be the opening state or the first cutter head state with the cutter head state being the opening state is identified, determining that the operation currently performed by theultrasonic knife 130 is the first operation, wherein the operation comprises punching or back cutting; if the cutter head state is identified to be the closing state or a second cutter head state with the cutter head state being closed is identified, the operation currently performed by theultrasonic knife 130 is determined to be a second operation, and the second operation comprises clamping cutting, coagulation or cutting. The surgical operation currently being performed by theultrasonic blade 130 is determined in this embodiment based only on the blade head status. The target operation in the embodiment of the present application refers to the second operation, and the second operation and the target operation are the same in meaning hereinafter.

Wherein determining the current surgical operation being performed by theultrasonic blade 130 based on the blade status and the electrical parameter comprises: if the cutter head state is identified to be the opening state or a first cutter head state with the cutter head state being the opening state is identified and the electrical parameter is changed, determining that the operation currently performed by theultrasonic knife 130 is a first operation, wherein the first operation comprises punching or back cutting; if the cutter head state is identified to be the closing state or a second cutter head state with the cutter head state being closed is identified and the electrical parameter is changed, determining that the operation currently performed by theultrasonic knife 130 is a second operation, wherein the second operation comprises clamping cutting, coagulation closing or cutting. In the embodiment, the current operation performed by theultrasonic scalpel 130 is determined according to the state of the scalpel head and the electrical parameter, wherein as long as the electrical parameter changes, the current operation is performed, the situation that no operation is currently performed or other operations are currently performed is eliminated, and the accuracy of determining the operation is improved.

Wherein determining the current surgical operation being performed by theultrasonic blade 130 based on the blade status and the electrical parameter comprises: if the cutter head state is identified to be the opening state or the first cutter head state with the cutter head state being the opening state is identified and the electrical parameter conforms to the electrical parameter curve corresponding to the first operation, determining that the currently executed operation of theultrasonic knife 130 is the first operation, wherein the first operation is punching or back cutting; if the cutter head state is identified to be the closed state or the second cutter head state with the cutter head state being closed is identified and the electrical parameter conforms to the electrical parameter curve corresponding to the second operation, determining that the operation currently executed by theultrasonic knife 130 is the second operation, wherein the second operation comprises clamping cutting, coagulating or cutting. In this embodiment, the current surgical operation being performed by theultrasonic scalpel 130 is determined according to the state of the scalpel head and the electrical parameter, wherein the current surgical operation being performed by theultrasonic scalpel 130 is determined only when the electrical parameter is required to be changed and the electrical parameter is required to conform to the electrical parameter curve of the corresponding operation, so that the accuracy of determining the surgical operation is further improved.

Wherein the electrical parameters include any one or more of power, voltage/current, frequency, impedance.

Wherein, not only the current operation performed by theultrasonic blade 130, but also the operation state of the operation (described below) can be determined according to the electrical parameter, and the tissue state corresponding to the operation (described below) can be determined according to the electrical parameter.

FIG. 3 is a schematic diagram of electrical parameters for clamping cut tissue according to an embodiment of the present disclosure. In the process of cutting tissue with theultrasonic blade 130, the electrical parameters of the ultrasonic blade energyoutput control system 100 are different, and the electrical parameters are correspondingly changed according to the tissue state, so that the tissue state can be further identified according to the change of the corresponding electrical parameters, the corresponding tissue state corresponds to a later state where the tissue is about to be processed and finished (e.g., the tissue in the clamping and cutting process is about to be broken or the tissue is about to be cut), a state where the tissue is already processed and finished (e.g., the tissue in the clamping and cutting process is about to be broken or the tissue is already cut), a state where the tissue is not finished, and the like, and the operation state can be further identified according to the change of the corresponding electrical parameters, for example, the later state where the operation is about to be finished and the operation finished state are included.

In fig. 3, the uppermost electrical parameter curve is the impedance curve, the middle electrical parameter curve is the voltage curve, and the lowermost electrical parameter curve is the power curve. Taking the power curve as an example, the time from 0 second to the first peak means that the impedance is decreased from high to maximum in the excitation phase of theultrasonic blade 130, where the energy output of the ultrasonic blade energyoutput control system 100 is rapidly increased to the maximum value, i.e., the value corresponding to the first peak of the power curve. When the energyoutput control system 100 starts to perform clamping and cutting, the energy output of the energyoutput control system 100 gradually increases to the expected energy at the initial stage of clamping and cutting, the energyoutput control system 100 also gradually enters a resonance state, the voltage and the power of the energyoutput control system 100 gradually increase at the moment, and the impedance gradually decreases as the system enters the resonance state; in the clamping and cutting process, as the temperature of thecutter head 131 increases, the tissue moisture is evaporated, the load of thecutter head 131 is gradually increased, and at the moment, the impedance, the voltage and the power of the ultrasonic cutter energyoutput control system 100 are all in an increasing state; at the end of the clamping and cutting process, along with the reduction of the cut tissue, the load of the cutter head is gradually reduced, and at the moment, the impedance, the voltage and the power of the ultrasonic knife energyoutput control system 100 are all in a reduced state; as theultrasonic blade 130 moves away from the tissue, the impedance, voltage, and power of the ultrasonic blade energyoutput control system 100 all drop rapidly.

FIG. 4 is a schematic diagram of the power and the state of the cutter head when clamping and cutting tissue according to the embodiment of the application. Wherein, the upper graph is a power schematic diagram when clamping and cutting tissues, the abscissa is time, and the ordinate is power; the lower diagram is a schematic view of a cutter head state, the abscissa is time, 1 of the ordinate represents that the cutter head state or the jaw state is a closed state, 0 represents that the cutter head state or the jaw state is an open state, and the value of the ordinate at this time is 1, which represents that the current cutter head state is a closed state. As can be seen from the power diagram, the change from the power beginning to the first peak means that in the excitation stage of theultrasonic blade 130, the energy output of the ultrasonic blade energyoutput control system 100 is rapidly increased to the power maximum value, and when the change from the power maximum value starts to decrease, it means that the ultrasonic blade energyoutput control system 100 starts to perform clamping cutting, the ultrasonic blade energyoutput control system 100 will gradually enter a resonance state, during the clamping cutting, as the temperature of theblade 131 increases, the tissue moisture evaporates, the load of theblade 131 of theultrasonic blade 130 gradually increases, and the power of the ultrasonic blade energyoutput control system 100 is in an increasing state, for example, in a period of about 1 second to 1.5 seconds; at the end of the clamped cut, the load on theblade 131 gradually decreases as the cut tissue decreases, and the power of the ultrasonic blade poweroutput control system 100 is reduced, for example, between about 1.5 seconds and 2 seconds, and the excitation is stopped at about 2.5 seconds for the state of the blade just before cutting.

FIG. 5 is a schematic diagram of power and tool tip status for multiple back cuts of tissue as provided by an embodiment of the present application. Fig. 6 is a schematic diagram of power and a state of a cutter head when perforating tissue according to an embodiment of the present application. The electrical parameter diagrams shown in fig. 5 and 6 can identify the surgical operation currently performed by theultrasonic blade 130, further determine the surgical operation status according to the electrical parameter, such as the operation in-progress status, the operation end status, the non-operation status, and the like, and further identify the tissue status according to the change of the corresponding electrical parameter, such as the perforation or back cutting, and the like.

As shown in FIG. 5, the upper graph is a power diagram of multiple back cuts of tissue, and zero in the lower graph indicates that the blade is in the open state. It can be seen in the power diagram that the change from the power representation to the first small peak means that the power of the ultrasonic blade energyoutput control system 100 decreases from the power to the first very low point (e.g., about 3 seconds) during the excitation phase to the power change of a tissue resection, where about 2 seconds is the gradual departure of theultrasonic blade 130 from the tissue, about 3 seconds is the departure of the tissue, and from the very low point to the next very low point is the power change of another tissue resection (e.g., about 3 seconds to about 5.7 seconds), and so on.

As shown in FIG. 6, the upper graph is a power diagram for perforating tissue, and zero in the lower graph indicates that the cutting head is in an open position. In the power diagram, it can be seen that the change from the power representation to the first small peak means that the ultrasonic blade energyoutput control system 100 begins perforating the tissue during the excitation phase, until there is a momentary fast-rising line around 2.5 seconds, meaning that a stroke has passed, and then beginning at the power maximum, meaning that theultrasonic blade 130 is gradually moving away from the tissue.

As can be seen from fig. 3 to 6, different surgical operations correspond to different electrical parameter curves, and the electrical parameter curves corresponding to different electrical parameters in the same surgical operation are different, so that the surgical operation currently performed by theultrasonic blade 130 is determined according to the state of the blade and the electrical parameters. The graph only lists some electrical parameter curves, such as power curves, and since power, voltage, impedance, frequency, etc. can be obtained by mutual conversion through physical formulas, other electrical parameter curves, such as frequency curves, voltage curves, impedance curves, etc., can also be obtained.

What is disclosed above is how to determine the surgical operation currently being performed by theultrasonic blade 130 based on the blade head state, and how to determine the surgical operation currently being performed by theultrasonic blade 130 based on the blade head state and the electrical parameter. For the following description, please refer to this part, and details will not be repeated.

After the blade status and the surgical procedure are determined, thetransducer 120 is controlled to provide corresponding kinetic energy, i.e., to control the energy delivered to theultrasonic blade 130, based on the blade status and the surgical procedure to control the energy output of theultrasonic blade 130. For example, thecontroller 111 controls the drivingunit 112 to provide corresponding electrical energy to thetransducer 120 according to the state of the cutter head and the surgical operation, so that thetransducer 120 provides corresponding kinetic energy matched with the electrical energy to control the energy output of theultrasonic blade 130.

In one usage scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to provide a fixed kinetic energy, i.e., control the energy delivered to thetransducer 120 to be a fixed energy, so as to control theultrasonic blade 130 to output the fixed energy when the sensing signal indicates that the blade status is in the open status and the blade status indicates that the surgical operation currently performed by theultrasonic blade 130 is the first operation; or when the sensing signal indicates that the blade status is an open status, the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasonic blade 130 is a first operation, thetransducer 120 is controlled to provide fixed kinetic energy, i.e., the energy delivered to thetransducer 120 is controlled to be fixed energy, so as to control theultrasonic blade 130 to output the fixed energy, wherein the first operation includes punching or back cutting. For example, thecontroller 111 controls the drivingunit 112 to supply a preset electric energy, which is determined by any one or more of a preset voltage, a preset current, or a preset power, to thetransducer 120, so that thetransducer 120 supplies a kinetic energy matching the preset voltage, the preset current, or the preset power, and controls theultrasonic blade 130 to output a fixed energy.

In one embodiment, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to identify a surgical operation currently performed by theultrasound blade 130 when the surgical operation is performed by theultrasound blade 130, determine a surgical operation status of the surgical operation according to an electrical parameter, such as power, or determine a tissue status corresponding to the surgical operation according to the electrical parameter, and control the energy delivered to theultrasound blade 130 according to the surgical operation and the surgical operation status, or the surgical operation and the tissue status.

In a usage scenario, when it is recognized that the surgical operation currently performed by theultrasonic blade 130 is a first operation and the surgical operation state of the surgical operation is an unoperated state, controlling the energy delivered to theultrasonic blade 130 to be a fixed energy, wherein the first operation includes perforation or back cutting; or, when it is recognized that the surgical operation currently being performed by theultrasonic blade 130 is the first operation and the surgical operation state of the surgical operation is the operation end state, controlling to reduce the energy delivered to theultrasonic blade 130 or controlling to stop the energy delivered to theultrasonic blade 130; alternatively, when it is recognized that the surgical operation currently being performed by theultrasonic blade 130 is the first operation and the surgical operation state of the first operation is changed from the operation-in-progress state to the operation-end state, the control reduces the energy delivered to theultrasonic blade 130 or the control stops the energy delivery to theultrasonic blade 130.

In one embodiment, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to identify a surgical operation currently performed by theultrasound blade 130 when theultrasound blade 130 performs the surgical operation, determine a tissue state corresponding to a second operation according to an electrical parameter, such as power, if the surgical operation currently performed by the ultrasound blade is the second operation, and control to reduce energy delivered to theultrasound blade 130 or stop energy delivery to theultrasound blade 130 when the tissue state is a tissue treatment ending state or a tissue treatment ending state, where the second operation includes cutting, clamping, cutting, or coagulating.

Wherein identifying the surgical procedure currently being performed by the ultrasonic blade 130 comprises: when the cutter head state of the cutter head is recognized to be an open first cutter head state, determining that the operation currently executed by the ultrasonic knife is a first operation; or when the cutter head state of the cutter head is recognized to be the first cutter head state of opening, and the power is changed, determining that the operation currently performed by the ultrasonic cutter is the first operation; or when the cutter head state of the cutter head is recognized to be the first cutter head state of opening and the power conforms to a power curve corresponding to the first operation, determining that the operation currently executed by the ultrasonic knife is the first operation; when the cutter head state of the cutter head is identified to be a closed second cutter head state, determining that the operation currently performed by the ultrasonic knife is a second operation; or when the cutter head state of the cutter head is identified to be a closed second cutter head state, and the power is changed, determining that the current operation performed by the ultrasonic knife is a target operation; or if the cutter head state is identified as the closed state or a second cutter head state with the cutter head state being closed is identified, and the power conforms to a power curve corresponding to a second operation, determining that the operation currently performed by the ultrasonic knife 130 is the second operation, wherein the first operation comprises punching or back cutting, and the second operation comprises clamping cutting, coagulating closing or cutting.

In one embodiment, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to determine a blade status of theblade 131 according to the sensing signal, determine a surgical operation currently performed by theultrasonic blade 130 according to the blade status and an electrical parameter, determine a surgical operation status of the surgical operation according to the electrical parameter, and control thetransducer 120 to provide corresponding kinetic energy, i.e., control the energy delivered to theultrasonic blade 130 according to the blade status, the surgical operation, and the surgical operation status, so as to control the energy output of theultrasonic blade 130. In this embodiment, the electric energy provided by thetransducer 120 is controlled according to the state of the tool bit, the surgical operation and the surgical operation state, that is, the energy delivered to theultrasonic blade 130 is controlled, so as to control theultrasonic blade 130 to output the corresponding energy in the corresponding different surgical operation states in different surgical operations under different tool bit states, thereby improving the surgical quality.

The operation state comprises an unoperated state, an operation in-progress state, an operation ending state and an operation ending state. Wherein the non-operation state means that the ultrasonic blade has not been operated although the ultrasonic blade has been excited; an in-process state means that the ultrasonic blade is performing a certain surgical operation, e.g., for punching or back-cutting, an in-process state means punching or back-cutting; the operation ending state means that a certain operation of the ultrasonic scalpel in progress is about to end, for example, for clamping cutting, the operation ending state means that clamping cutting is about to end; the end-of-operation state means that the ultrasonic blade has finished a certain surgical operation, such as for punching or backcutting, the end-of-operation state means that punching or backcutting is finished.

When the sensing signal indicates that the blade state is the open state and the blade state indicates that the currently performed surgical operation of theultrasonic blade 130 is the first operation, the determining the surgical operation state of the surgical operation according to the electrical parameter includes: if the electrical parameter is reduced to the corresponding first preset parameter threshold value, determining that the operation state of the operation is an operation ending state; otherwise, if the electrical parameter is changed, the operation state of the operation is determined to be the operation in-progress state.

If the electrical parameter is power, the first preset parameter threshold corresponds to a first preset power threshold, if the electrical parameter is voltage or current, the first preset parameter threshold corresponds to a first preset voltage or first preset current threshold, if the electrical parameter is frequency, the first preset parameter threshold corresponds to a first preset frequency threshold, if the electrical parameter is impedance, the first preset parameter threshold corresponds to a first preset impedance threshold, wherein the first preset power threshold, the first preset voltage or current threshold, the first preset frequency threshold or the first preset impedance threshold are set in advance through experiments or other manners.

The first preset parameter threshold is smaller than a minimum parameter value corresponding to the operation state of the ultrasonic blade energyoutput control system 100 being in an operation in-progress state, for example, the first preset power threshold is smaller than a minimum power value corresponding to the ultrasonic blade energyoutput control system 100 being used for punching or back cutting, or the first preset voltage threshold is smaller than a minimum voltage value corresponding to the ultrasonic blade energyoutput control system 100 being used for punching or back cutting. If the electrical parameter is reduced to the corresponding first preset parameter threshold, it means that the surgical operation is finished, i.e. the surgical operation status of the surgical operation is the operation end status. Otherwise, if the electrical parameter changes, it means that a punch or back cut operation is being performed.

When the sensing signal indicates that the blade status is the off status and the blade status indicates that the currently performed surgical operation of theultrasonic blade 130 is the second operation, the determining the surgical operation status according to the electrical parameter includes: when the electrical parameter is changed from the minimum value to the maximum value and then starts to decline from the maximum value, and the decline parameter value exceeds a second preset parameter threshold value, determining that the operation state of the second operation is the operation ending state; otherwise, determining the operation state of the second operation as the operation in-progress state. For example, when the cutter head is in the closed state and clamping and cutting are performed, when the electrical parameter changes from a minimum value to a maximum value and then decreases from the maximum value, and the decreasing parameter value exceeds a second preset parameter threshold value, it is determined that the surgical operation of clamping and cutting is about to finish cutting, which means that the tissue will be cut or already cut, otherwise, it means that the tissue is in the non-cut state while clamping and cutting.

If the electrical parameter is power, the second preset parameter threshold corresponds to a second preset power threshold, if the electrical parameter is voltage or current, the second preset parameter threshold corresponds to a second preset voltage or second preset current threshold, if the electrical parameter is frequency, the second preset parameter threshold corresponds to a second preset frequency threshold, if the electrical parameter is impedance, the second preset parameter threshold corresponds to a second preset impedance threshold, wherein the second preset power threshold, the second preset voltage or current threshold, the second preset frequency threshold, or the second preset impedance threshold are set in advance through experiments or other manners.

For determining the operation status of the operation according to the electrical parameter, please refer to the description of this section, which will not be described in detail later.

In one usage scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to provide a fixed kinetic energy to control theultrasonic blade 130 to output a fixed energy, i.e., control the energy delivered to theultrasonic blade 130 to be a fixed energy, when the sensing signal indicates that the blade status is an open status, the blade status indicates that the surgical operation currently performed by theultrasonic blade 130 is a first operation, and the electrical parameter (e.g., the electrical parameter variation) indicates that the surgical operation status of the first operation is an unoperated status, where the first operation includes punching or back cutting. That is, when the cutter head is in the open state and the perforation or the back incision is not performed, the corresponding operation of perforation or back incision is accurately performed, and at the time, the fixed energy is output to facilitate the corresponding operation.

In one usage scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to decrease the kinetic energy to control theultrasonic blade 130 to decrease the energy output, i.e., to control the energy delivered to theultrasonic blade 130, or to control thetransducer 120 to stop outputting the kinetic energy to control theultrasonic blade 130 to stop outputting the energy output, i.e., to control the energy delivered to theultrasonic blade 130, when the sensing signal indicates that the blade-head state is the open state, the blade-head state indicates that the surgical operation currently performed by theultrasonic blade 130 is the first operation, or the blade-head state and the electrical parameter indicate that the surgical operation currently performed by theultrasonic blade 130 is the first operation, and the electrical parameter (e.g., the electrical parameter variation) indicates that the surgical operation state of the first operation is the operation-end state, wherein the first operation includes punching or back cutting. In this embodiment, when the blade head is in the open state, the surgical operation is a perforation or a back cut, and the electrical parameter (e.g., the amount of change in the electrical parameter) indicates the end of the perforation or the back cut, thetransducer 120 is controlled to reduce the kinetic energy or stop providing the kinetic energy, so as to avoid the possibility of accidentally injuring other tissues when theblade head 131 of theultrasonic blade 130 is withdrawn from the tissues, thereby improving the quality of the surgery.

Wherein thetransducer 120 is controlled to reduce the kinetic energy, the reduced electrical energy, such as the first electrical energy, is provided to thetransducer 120 by thecontroller 111, the reduced first electrical energy drives thetransducer 120 to provide a kinetic energy matching the first electrical energy, and thus thetransducer 120 reduces the kinetic energy to reduce the energy output of theultrasonic blade 130, i.e., to control the reduction of the energy delivered to theultrasonic blade 130. Wherein the first electric energy is lower than a preset electric energy, and the first electric energy is determined by any one or more of a first voltage, a first current or a first power. The first voltage is lower than a preset voltage, the first current is lower than a preset current, and the first power is lower than a preset power.

Wherein thetransducer 120 is controlled to stop providing kinetic energy, thecontroller 111 is informed to stop thedriving unit 112 from outputting electrical energy to thetransducer 120, or the electrical energy provided to thetransducer 120 is set to zero.

In one usage scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to reduce the kinetic energy to control theultrasonic blade 130 to reduce the energy output, i.e., to control the energy delivered to theultrasonic blade 130 to reduce, or to control thetransducer 120 to stop outputting the kinetic energy to control theultrasonic blade 130 to stop the energy output, i.e., to control the energy delivered to theultrasonic blade 130 to stop delivering, when the sensing signal indicates that the blade status is in the open state, the blade status indicates that the surgical operation currently performed by theultrasonic blade 130 is in the first operation, or the blade status and the electrical parameter indicate that the surgical operation status of the first operation is changed from the in-process state to the end-of-operation state, where the first operation includes punching or back cutting. The difference between this embodiment and the previous embodiment is that when the surgical operation status of the first operation, which is characterized by the electrical parameter (e.g., the electrical parameter variation), changes from the operation-in-progress status to the operation-end status, is defined in this embodiment, it means that the surgical operation corresponding to the first operation is performed from the current execution to the end execution, so that it is more accurately determined that the surgical operation corresponding to the first operation, such as punching or back cutting, has been ended, and at this time, the energy output of theultrasonic blade 130 is reduced or stopped to improve the surgical quality.

In one usage scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to reduce the kinetic energy to control theultrasonic blade 130 to reduce the energy output, i.e., to control theultrasonic blade 130 to reduce the energy delivered to theultrasonic blade 130, or to control thetransducer 120 to stop outputting the kinetic energy to control theultrasonic blade 130 to stop outputting the energy output, i.e., to control theultrasonic blade 130 to stop delivering the energy to theultrasonic blade 130, when the sensing signal indicates that the blade status is in the off status, the blade status indicates that the surgical operation performed by theultrasonic blade 130 is in the second operation, or the blade status and the electrical parameter indicate that the surgical operation performed by theultrasonic blade 130 is in the end-of-operation status, and the electrical parameter (e.g., the electrical parameter variation) indicates that the surgical operation performed by theultrasonic blade 130 is in the second operation, wherein the second operation includes clamping cutting, coagulating or cutting. For example, when the tool bit state is the closed state, and the clamping cutting is about to be completed, thetransducer 120 is controlled to reduce the kinetic energy to control theultrasonic blade 130 to reduce the energy output, or thetransducer 120 is controlled to stop outputting the kinetic energy to control theultrasonic blade 130 to stop outputting the energy output. The manner of controlling thetransducer 120 to reduce the kinetic energy or the manner of controlling thetransducer 120 to stop providing the kinetic energy is described above. In this embodiment, when the cutting head is in the closed state, and the clamping and cutting are performed, the energy output of theultrasonic blade 130 is reduced or stopped when the clamping and cutting are about to be completed, so as to prevent other tissues from being accidentally injured and improve the operation quality.

In a usage scenario, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to control thetransducer 120 to decrease the kinetic energy to control theultrasonic blade 130 to decrease the energy output, or control thetransducer 120 to stop outputting the kinetic energy to control theultrasonic blade 130 to stop outputting the energy output, when the sensing signal indicates that the blade status is in the off status, the blade status indicates that the surgical operation currently performed by theultrasonic blade 130 is the second operation, or the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasonic blade 130 is the second operation, and the electrical parameter (such as the electrical parameter variation) indicates that the surgical operation status of the second operation is the operation ending status, wherein the second operation includes clamping cutting, coagulating or cutting to improve the surgical quality.

In one embodiment, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to determine a blade head state of theblade head 131 according to the sensing signal, determine a surgical operation currently performed by theultrasonic blade 130 according to the blade head state, or determine a surgical operation currently performed by theultrasonic blade 130 according to the blade head state and the electrical parameter, determine a tissue state corresponding to the surgical operation according to the electrical parameter, and control thetransducer 120 to provide corresponding kinetic energy according to the blade head state, the surgical operation, and the tissue state, that is, control the energy delivered to theultrasonic blade 130, so as to control the energy output of theultrasonic blade 130. In this embodiment, the energy output of theultrasonic blade 130 is controlled based on the blade head state, the surgical procedure, and the tissue state. Wherein, the tissue state corresponding to the operation is determined according to the electrical parameter, and the energy output of theultrasonic knife 130 is further controlled according to the tissue state.

For the first operation such as punching or back cutting, the tissue state includes a state in which the punching or back cutting is being performed, the punching or back cutting is completed, the punching or back cutting is not performed, and for the second operation such as clamping cutting, coagulation or cutting, the tissue state includes a state in which the tissue is about to be processed (e.g., the tissue in the clamping cutting is about to be cut or is about to be cut), a state in which the tissue is processed (e.g., the tissue in the clamping cutting is separated or is cut), a state in which the tissue is not processed (e.g., the tissue in the clamping cutting is not separated), and the like.

When the sensing signal indicates that the blade head state is the open state and the blade head state indicates that the currently performed surgical operation of theultrasonic blade 130 is the first operation, the determining the tissue state corresponding to the surgical operation according to the electrical parameter includes: if the electrical parameter is reduced to the corresponding first preset parameter threshold value, determining that the tissue state corresponding to the surgical operation is a punching or back cutting ending state; otherwise, if the electrical parameter changes, determining that the tissue state corresponding to the surgical operation is punching or back cutting.

When the sensing signal indicates that the blade head state is the closed state and the blade head state indicates that the currently performed surgical operation of theultrasonic blade 130 is the second operation, determining the tissue state corresponding to the surgical operation according to the electrical parameter includes: when the electrical parameters are identified to be from the minimum value and the maximum value, and the descending parameter value is identified to exceed the corresponding second preset parameter threshold value, determining that the tissue state corresponding to the second operation is the tissue to-be-finished state or the tissue processed finished state; otherwise, determining that the organization state corresponding to the second operation is an organization processing unfinished state. For example, when the electrical parameter is power, when a power minimum value and a power maximum value are identified according to the power, and the identified power drops beyond a corresponding power threshold, it is determined that the tissue state corresponding to the second operation is a tissue treatment-to-be-finished state or a tissue treatment-finished state, otherwise, it is determined that the tissue state corresponding to the second operation is a tissue treatment-unfinished state.

Further, determining a tissue state corresponding to the surgical procedure based on the electrical parameter includes: when the fact that the electrical parameter changes from a minimum value to a maximum value and then begins to decline from the maximum value is recognized, and the decline parameter value exceeds a corresponding second preset parameter threshold value, the tissue state corresponding to the operation is determined to be a state that the tissue is about to be processed and is finished or the tissue is processed and is finished; otherwise, determining that the operation state corresponding to the operation is a tissue processing unfinished state. For example, when the electrical parameter is power, when it is identified that the power increases from a power minimum value to a power maximum value, and then decreases from the power maximum value, and the decreased power value that decreases from the power maximum value exceeds the corresponding power threshold, it is determined that the tissue state corresponding to the second operation is a tissue treatment-imminent end state or a tissue treatment-ended state; otherwise, determining that the organization state corresponding to the second operation is an organization processing unfinished state.

In some usage scenarios, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to control thetransducer 120 to provide a fixed kinetic energy to control theultrasound blade 130 to output a fixed energy when the sensing signal indicates that the blade status is in the open state, the blade status indicates that the surgical operation currently performed by theultrasound blade 130 is the first operation, or the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasound blade 130 is the first operation, and the electrical parameter indicates that the tissue status corresponding to the first operation is not perforated or back-cut;

or, when the sensing signal indicates that the blade state is an open state, the blade state indicates that the surgical operation currently performed by theultrasonic blade 130 is the first operation, or the blade state and the electrical parameter indicate that the surgical operation currently performed by theultrasonic blade 130 is the first operation, and the electrical parameter indicates that the tissue state corresponding to the first operation is punching or back cutting, thetransducer 120 is controlled to provide fixed kinetic energy to control theultrasonic blade 130 to output fixed energy; or,

when the sensing signal indicates that the blade status is the open status, the blade status indicates that the surgical operation currently performed by theultrasonic blade 130 is the first operation, or the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasonic blade 130 is the first operation, and the electrical parameter indicates that the tissue status corresponding to the first operation is the end of perforation or back cut, thetransducer 120 is controlled to reduce the kinetic energy to control theultrasonic blade 130 to reduce the energy output, i.e., to control to reduce the energy delivered to theultrasonic blade 130, or thetransducer 120 is controlled to stop providing the kinetic energy to provide the energy output of theultrasonic blade 130, i.e., to control to stop delivering the energy to theultrasonic blade 130.

In some usage scenarios, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, controls thetransducer 120 to provide a fixed energy to control theultrasound blade 130 to output the fixed energy when the sensing signal indicates that the blade status is in the off state, the blade status indicates that the surgical operation currently performed by theultrasound blade 130 is the second operation, or the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasound blade 130 is the second operation, and the electrical parameter (e.g., the electrical parameter variation) indicates that the tissue status corresponding to the surgical operation is the operation processing unfinished state or the operation unprocessed state; or,

when the sensing signal indicates that the blade status is in the off state, the blade status indicates that the surgical operation currently performed by theultrasonic blade 130 is the second operation, or the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasonic blade 130 is the second operation, and the electrical parameter (e.g., the electrical parameter variation) indicates that the tissue status corresponding to the surgical operation is the tissue treatment ending status or the tissue treatment ending status, thetransducer 120 is controlled to reduce the kinetic energy to control theultrasonic blade 130 to reduce the energy output, i.e., to control the energy delivered to theultrasonic blade 130 to be reduced, or thetransducer 120 is controlled to stop outputting the kinetic energy to control theultrasonic blade 130 to stop outputting the energy, i.e., to control the energy to be delivered to theultrasonic blade 130 to be stopped.

In one embodiment, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to obtain the energy control identifier of the preset setting. Wherein the preset energy control mark can be determined by a preset set gear or a preset set energy operation state.

For example, in the ultrasonicmain unit 110 or in theultrasonic blade 130, different shift positions are provided, and the shift positions can be represented according to shift position keys or shift position buttons or shift position switches. The different gears comprise a first gear, a second gear and a third gear, wherein the first gear supports/allows energy reduction, the second gear does not support/forbids energy reduction, the third gear supports/allows energy output stopping, and the fourth gear does not support/forbids energy output stopping. The method comprises the steps that values from a first gear to a fourth gear are represented through an energy control identifier, the first gear is selected or set or opened in advance, the energy control identifier is set to be 1, the reduction energy is supported by representation, if the second gear is selected or set or opened in advance, the energy control identifier is set to be 2, the reduction energy is forbidden or not supported by representation, the third gear is selected or set or opened in advance, the energy control identifier is set to be 3, the stop energy output is supported/allowed by representation, and if the fourth gear is selected or set or opened in advance, the energy control identifier is set to be 4, and the stop energy output is forbidden/not supported by representation. Or if not pre-selected or pre-set, the default energy control flag is set to any of 1, 2, 3 or 4, such as 2. Correspondingly, the energy output state during the surgical operation is divided into three cases: so as to fix energy output, reduce energy output and stop energy output.

In one case, only the first and second gears can be set, which means that either the reduction of energy is supported or allowed or the reduction of energy is not supported or allowed, and correspondingly, the energy output state during the surgical operation is divided into two cases: so as to fix the energy output and reduce the energy output. In one case, only gear three and gear four can be set, indicating that either the stopping of the energy output is supported/allowed or the stopping of the energy output is supported/allowed, and correspondingly, the energy output state during the surgical operation is divided into two cases: the energy output is fixed and stopped.

For example, in a display device of the ultrasound host (if the display device is available), whether a button or a key supporting energy reduction is displayed, and whether a button or a key supporting energy output stopping is displayed, if the button or the key supporting energy reduction is triggered in advance, an energy operation state is set to 1, which represents that energy reduction is supported/allowed in the surgical operation process, otherwise, the energy operation state is set to 2, which represents that energy reduction is prohibited/energy reduction is not supported in the surgical operation process, if the button or the key stopping energy output is triggered in advance, the energy operation state is set to 3, which represents that energy output is supported/allowed to stop in the surgical operation process, and if the energy operation state is set to 4, which represents that energy output stopping is prohibited/not supported in the surgical operation process.

In one embodiment, only the button or key supporting the reduction of energy may be triggered, and accordingly, the energy output state during the surgical operation is divided into two cases: output with fixed energy, reduce energy output; in one embodiment, only the button or key for stopping energy output may be triggered, and accordingly, the energy output state during the surgical operation may be divided into two cases: the energy output is fixed and stopped.

Correspondingly, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to identify a surgical procedure currently being performed by the ultrasound blade, determine a tissue state corresponding to the surgical procedure according to an electrical parameter, such as power, and control energy delivered to theultrasound blade 130 according to the surgical procedure, the tissue state, and the energy control identifier.

In a usage scenario, when the surgical operation currently being performed by theultrasonic blade 130 is identified as a second operation, the tissue state corresponding to the second operation is determined to be a tissue treatment ending state or a tissue treatment ending state according to the power, and the energy control identifier indicates that the energy reduction is supported, the energy delivered to theultrasonic blade 130 is controlled to be reduced, or the energy delivery to theultrasonic blade 130 is controlled to be stopped; alternatively, when the operation currently performed by theultrasonic blade 130 is identified as the second operation, the tissue state corresponding to the second operation is determined to be the tissue treatment ending state or the tissue treatment ending state according to the power, and the energy control identifier indicates that the reduced energy is not supported, the energy delivered to theultrasonic blade 130 is controlled to be the fixed energy.

In a usage scenario, when it is recognized that the surgical operation currently being performed by theultrasonic blade 130 is a first operation, the electrical parameter indicates that the tissue state corresponding to the first operation is a perforation or back-cut ending state, and the energy control identifier indicates that the energy reduction is supported, controlling to reduce the energy delivered to theultrasonic blade 130, or controlling to stop delivering the energy to theultrasonic blade 130; alternatively, when it is recognized that the surgical operation currently being performed by theultrasonic blade 130 is the first operation, the electrical parameter indicates that the tissue state corresponding to the first operation is the perforation or back-cut end state, and the energy control indicator indicates that the reduced energy is not supported, the energy delivered to theultrasonic blade 130 is controlled to be the fixed energy.

Correspondingly, the ultrasonicmain unit 110, such as thecontroller 111 of the ultrasonicmain unit 110, is further configured to determine a blade status of theblade 131 according to the sensing signal, determine a surgical operation currently performed by theultrasonic blade 130 according to the blade status, or determine a surgical operation currently performed by theultrasonic blade 130 according to the blade status and the electrical parameter, determine a surgical operation status of the surgical operation according to the electrical parameter, and control thetransducer 120 to provide corresponding kinetic energy according to the blade status, the surgical operation status, and the energy control flag, so as to control the energy output of theultrasonic blade 130, i.e., control the energy delivered to theultrasonic blade 130. Thetransducer 120 is further controlled to provide corresponding kinetic energy in this embodiment according to the energy control indicia to freely effect a reduction or stopping of the energy output of theultrasonic blade 130.

In some usage scenarios, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to control thetransducer 120 to decrease the kinetic energy to control theultrasound blade 130 to decrease the energy output, that is, to control to decrease the energy delivered to theultrasound blade 130, when the sensing signal indicates that the blade-head state is the open state, the blade-head state indicates that the surgical operation currently performed by theultrasound blade 130 is the first operation, or the blade-head state and the electrical parameter indicate that the surgical operation currently performed by theultrasound blade 130 is the first operation, the electrical parameter indicates that the surgical operation state of the first operation is the end-of-operation state, or the electrical parameter indicates that the surgical operation state of the first operation is changed from the in-progress state to the end-of-operation state, and the energy control identifier indicates that the decrease of the energy is supported;

For example, in the case where the blade-end state is the open state, the perforation or back-cutting operation has been completed, and the reduced energy is supported, thecontroller 111 provides thetransducer 120 with a reduced electrical energy, such as a second electrical energy, which drives thetransducer 120 to provide a kinetic energy matching the second electrical energy, so that thetransducer 120 reduces the kinetic energy to reduce the energy output of theultrasonic blade 130, i.e., to reduce the energy delivered to theultrasonic blade 130. Wherein the second electric energy is lower than the preset electric energy, and the second electric energy is determined by any one or more of a second voltage, a second current or a second power. The second voltage is lower than the preset voltage, the second current is lower than the preset current, and the second power is lower than the preset power. The second electric energy may be the same as or different from the first electric energy. In the case where the cutter head state is the open state, the operation of perforating or cutting the back has been completed, and the reduction of energy is not supported/inhibited, thecontroller 111 supplies the preset electric energy to thetransducer 120 to drive thetransducer 120 to supply the kinetic energy matched with the preset electric energy, so that thetransducer 120 supplies the fixed kinetic energy, so that theultrasonic blade 130 outputs the fixed energy.

In some usage scenarios, theultrasound host 110, such as thecontroller 111 of theultrasound host 110, is further configured to control thetransducer 120 to decrease the kinetic energy to control theultrasound blade 130 to decrease the energy output, i.e., to control to decrease the energy delivered to theultrasound blade 130, when the sensing signal indicates that the blade status is in the off state, the blade status indicates that the surgical operation currently performed by theultrasound blade 130 is the second operation, or the blade status and the electrical parameter indicate that the surgical operation currently performed by theultrasound blade 130 is the second operation, the electrical parameter indicates that the surgical operation status of the second operation is the operation ending state or the operation ending state, and the energy control flag indicates that the energy reduction is supported;

Wherein the third electric energy is lower than the preset electric energy, and the third electric energy is determined by any one or more of a third voltage, a third current or a third power. The third voltage is lower than the preset voltage, the third current is lower than the preset current, and the third power is lower than the preset power. The third electric energy may be the same as or different from the second electric energy and the first electric energy. In the case where the cutting head is in the closed state, the surgical operation for clamping and cutting has been completed or is about to be completed, and the reduction of energy is not supported, thecontroller 111 provides the preset electric energy to thetransducer 120 to drive thetransducer 120 to provide the kinetic energy matched with the preset electric energy, so that thetransducer 120 provides the fixed kinetic energy, so that theultrasonic blade 130 outputs the fixed energy.
