Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes an electric planer tool, a control method, a control device and a storage medium thereof according to embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an electric planer according to an embodiment of the invention, and referring to fig. 1, the control method of the electric planer may include the steps of:
and step S101, when the motor is controlled to drive the cutter head to rotate, the liquid passing state inside the cutter head is obtained.
It should be noted that, in the excision operation of various tissues such as skin, muscle, ligament, bone, etc., it is necessary to use an electric planer tool to excise diseased tissue or redundant tissue, fig. 2 is a schematic structural diagram of the electric planer tool in a specific example, fig. 3 is a partial enlarged view of fig. 2, and referring to fig. 2 and 3, the electric planer tool 200 includes a tool bit 201 and a tool body 202, and the tool body 202 includes a motor 203, wherein the tool bit 201 is used for cutting diseased tissue or redundant tissue, the motor 203 is used for driving the tool bit 201 to rotate, and meanwhile, a liquid channel 204 is provided in the electric planer tool 200 for allowing liquid to flow through the inside of the tool bit.
It will be appreciated that the arrangement of the liquid passages is not particularly limited as long as liquid can flow through the interior of the cutter head. Specifically, one end of the liquid channel may be located at the blade (e.g., the handle end of the blade), the other end of the liquid channel may be located at the blade (e.g., the working end of the blade), one of the two ends is a liquid inlet end, and the other end is a liquid outlet end, so that the liquid channel may be used to inject liquid into or extract liquid from a patient. For example, saline solution may be injected into the patient through the fluid channel during the surgical procedure, or saline solution, tissue waste solution, or other fluid may be withdrawn from the patient through the fluid channel. In addition, the liquid channel can also be that the channel path passes through the inside of the cutter head, and the liquid inlet end and the liquid outlet end of the liquid channel are both positioned at the cutter body (such as the end part of the handle of the cutter body), so that liquid can flow into the inside of the cutter head from the liquid inlet end of the cutter body and then flow out from the liquid outlet end of the cutter body, for example, in the bone drilling operation process, water or other cooling liquid can be circulated through the liquid channel to cool the cutter head so as to prevent thermal damage caused by friction heat generation.
Specifically, for different clinical requirements, when the electric planing tool is used, the liquid passing may or may not need to be started, or the liquid passing may need to be started in a part of the operation process, and the liquid passing may need to be closed in a part of the operation process, for example, the tool bit is started to rotate before the operation, and after the tool bit is positioned at the patient, the liquid passing is started to extract or inject physiological saline.
When the cutter head rotates at a high speed, the cutting friction can generate heat rapidly, if no liquid passes through the liquid channel, the temperature of the cutter head can rise suddenly, if the cutter head still continues to operate, plastic components (such as the plastic inner sleeve 205 and the plastic outer sleeve 206 shown in fig. 2 and 3) of the cutter head can be melted and adhered together, conversely, if the liquid passes through the liquid channel inside the cutter head, a large amount of heat can be absorbed due to the fact that the liquid is usually water, physiological saline or other solution, and the temperature of the cutter head can be effectively prevented from being too high, so that the liquid passing state is an important factor affecting the temperature of the cutter head. Therefore, when the motor is controlled to drive the cutter head to rotate, the liquid state inside the cutter head is firstly obtained, and the liquid state is used as the basis for adopting different control modes subsequently.
Further, the liquid passing state inside the cutter head is obtained, wherein the liquid passing state inside the cutter head comprises the steps of obtaining humidity information inside the cutter head and obtaining the liquid passing state inside the cutter head according to the humidity information.
That is, the liquid passing state can be reflected by the humidity information inside the cutter head. Specifically, humidity information in the cutter head can be detected through sensors such as a humidity sensor, a water immersion sensor, a flow sensor and a liquid level sensor, and the liquid passing state is determined according to the humidity information. It should be understood that, regarding the state of fluid passing through the interior of the cutter head, the present application is not limited to being obtained by a sensor or the like, and for example, the electric planer may be provided with a fluid-pumping device (such as a negative pressure aspirator) for driving the pumping, injecting or circulating of the fluid in the channel, in which case the electric planer may be communicatively connected to the fluid-pumping device to obtain data information (such as pressure or flow rate) related to the fluid-pumping device, and the state of fluid passing through the interior of the cutter head may be obtained according to the data information.
Optionally, the humidity information inside the cutter head is obtained by a sensor, which is arranged in the liquid channel.
Specifically, the sensor may include a humidity sensor, a water immersion sensor, a flow sensor, a liquid level sensor, and the like. If the humidity sensor is used to obtain the humidity information of the interior of the cutter head, referring to fig. 3, the humidity sensor 207 may be positioned on the inner wall of the liquid channel 204, so that the probe of the humidity sensor 207 is located in the liquid channel 204, and the humidity sensor 207 is preferably disposed close to the cutter head 201, so as to improve the accuracy of detection. If the flow sensor is used to obtain the humidity information in the cutter head, the flow sensor can be positioned on the inner wall of the liquid channel, so that the probe of the flow sensor is positioned in the liquid channel, and for the liquid channel which is partially in a pipeline structure and partially in a cavity structure, the flow sensor is preferably arranged at the pipeline structure of the liquid channel. For water immersion sensors and liquid level sensors, the arrangement is similar to that of humidity sensors and flow sensors, and detailed description thereof will be omitted.
Step S102, if the liquid is not filled in the cutter head, controlling the motor to drive the cutter head to rotate according to a first rotating speed, wherein the first rotating speed is a smaller value of a target required rotating speed and a maximum allowable rotating speed, and the maximum allowable rotating speed is a maximum rotating speed when the liquid is not filled in the cutter head and the cutter head is not adhered.
That is, when the cutter head rotates, if the set rotation speed of the cutter head is expressed as a target required rotation speed Rset (which may be input according to clinical requirements) and the maximum rotation speed of the cutter head when the cutter head is not connected is expressed as a maximum allowable rotation speed Rsafety (which may be determined according to experimental study or experience) when the liquid is not introduced into the cutter head, the motor is controlled to rotate according to the target required rotation speed Rset when the target required rotation speed Rset is less than or equal to the maximum allowable rotation speed Rsafety, and the motor is controlled to rotate according to the maximum allowable rotation speed Rsafety when the target required rotation speed Rset is greater than the maximum allowable rotation speed Rsafety. That is, when the set rotation speed of the cutter head is higher than the maximum allowable rotation speed Rsafety, the rotation speed of the cutter head is controlled to be reduced to the maximum allowable rotation speed Rsafety, so that the rotation speed of the cutter head is not higher than the maximum allowable rotation speed Rsafety, and adhesion caused by high-speed rotation of the cutter head can be effectively prevented.
Conversely, if the liquid is filled in the cutter head, the motor is controlled to drive the cutter head to rotate according to the target required rotating speed Rset. That is, in the tool bit rotation process, when detecting that the tool bit is inside to be led with liquid, because this liquid can absorb a large amount of heat, can effectively prevent that tool bit temperature from being too high, can not lead to the emergence of tool bit adhesion problem, consequently need not to carry out extra adjustment, only need according to clinical needs, control the tool bit rotate according to target demand rotational speed Rset can.
Therefore, when the control motor drives the cutter head to rotate, the liquid passing state inside the cutter head is obtained, if no liquid is passed into the cutter head, the motor is controlled to drive the cutter head to rotate according to the first rotating speed, wherein the first rotating speed is a smaller value of the target required rotating speed and the maximum allowable rotating speed, and the maximum allowable rotating speed is a maximum rotating speed when no liquid passes through the inside of the cutter head and the cutter head is not adhered. On the other hand, compared with a control method which only detects the temperature of the cutter head and controls the cutter head to stop running once the temperature of the cutter head is higher than a set protection value, the control method can effectively reduce the frequency of interruption of the operation of the cutter head and has good operation consistency.
In one embodiment, when the motor is controlled to drive the cutter head to rotate, the method further comprises the steps of obtaining temperature information of the cutter head and controlling the motor according to the temperature information.
That is, when solving the adhesion problem that leads to because of the tool bit high-speed rotation, not only can control the motor according to the logical liquid state of tool bit inside, can also control the motor according to the temperature information of tool bit to realize dual protection, thereby further prevent that the tool bit from adhering.
It should be understood that the control of the motor according to the temperature information may be control of the start-stop state of the motor or control of the rotation speed of the motor, which is not particularly limited in the present application. It should be further understood that the control of the motor according to the temperature information may be performed throughout the whole process of the rotation of the cutter head, that is, from the start of the rotation of the cutter head controlled by the motor until the stop of the rotation of the cutter head controlled by the motor, or may be performed at a certain stage of the rotation of the cutter head, for example, at a stage of the rotation of the cutter head driven by the motor controlled according to the first rotation speed, for example, at a stage of the rotation of the cutter head exceeding a certain set threshold, or at a stage of determining that the interior of the cutter head is flooded, etc., which is not particularly limited in this application.
Optionally, controlling the motor according to the temperature information comprises controlling the motor to stop working if the temperature information is greater than or equal to a preset temperature threshold, wherein the preset temperature threshold is the minimum temperature when the cutter head is adhered.
That is, the lowest temperature inside the tip when the tip is adhered can be determined through experimental study or experience, and the temperature value is taken as a preset temperature threshold. In the tool bit rotation process, the actual temperature of the tool bit can be obtained in real time, when the actual temperature is greater than or equal to the preset temperature threshold value, the tool bit is indicated to have adhesion risk, and the motor is controlled to stop driving the tool bit to rotate at the moment. After a certain period of cooling, the motor can be restarted, and the motor is controlled through the liquid passing state and the temperature information.
Further, temperature information of the cutter head can be obtained by a temperature sensor, as shown in fig. 3, the temperature sensor 208 is disposed close to the cutter head 201, and the temperature sensor 208 includes a probe for detecting temperature, and the probe is disposed apart from the liquid channel 204.
Specifically, when temperature information of the cutter head is obtained through the temperature sensor 208, the temperature sensor 208 and the cutter head 201 can be arranged close to each other, and the temperature sensor 208 and the working end of the cutter head 201 are preferably arranged close to each other, so that the temperature conduction time is shortened, more accurate instant temperature information is obtained, and the reliability of the anti-adhesion control method is improved.
Fig. 4 is a flowchart of a control method of an electric planer according to an embodiment of the invention, and referring to fig. 4, the control method of the electric planer may include the steps of:
Step S301, when the motor is controlled to drive the cutter head to rotate, the liquid passing state inside the cutter head is obtained.
For example, humidity information in the cutter head is obtained through a humidity sensor, and the liquid passing state in the cutter head is obtained according to the humidity information.
And S302, judging whether the target required rotation speed Rset is less than or equal to the maximum allowable rotation speed Rsafety or not if the liquid is not filled in the cutter head. If so, the target required rotation speed Rset is used as a first rotation speed to control the motor to drive the cutter head to rotate, and if not, the maximum allowable rotation speed Rsafety is used as the first rotation speed to control the motor to drive the cutter head to rotate. If the liquid is filled in the cutter head, the motor is controlled to drive the cutter head to rotate according to the target required rotating speed Rset.
Step S303, acquiring temperature information of the cutter head through a temperature sensor, and judging whether the temperature information is more than or equal to a preset temperature threshold. If yes, the cutter head is controlled to stop running, otherwise, the step S301 is executed, and the liquid passing state inside the cutter head is continuously obtained.
In summary, according to the control method of the electric planer tool according to the embodiment of the invention, when the control motor drives the cutter head to rotate, the liquid passing state inside the cutter head is obtained, if the cutter head is not in liquid passing state, the motor is controlled to drive the cutter head to rotate according to the first rotation speed, wherein the first rotation speed is a smaller value of the target required rotation speed and the maximum allowable rotation speed, and the maximum allowable rotation speed is a maximum rotation speed when the cutter head is not in liquid passing state and the cutter head is not adhered. Therefore, the problem of adhesion caused by high-speed rotation of the cutter head can be effectively solved, the running continuity is good, and the condition that the running is frequently interrupted is not easy to occur.
