Electrosurgery rotating angle control deviceTechnical field
The present invention relates to medical surgery instrument fields, and in particular to a kind of electrosurgery rotating angle control device.
Background technique
Electrosurgical instrument is the surgical operating instrument for electric coagulation hemostasis in surgical procedure or cutting tissue, in clinicOn it is commonly used.Currently, Electrosurgical instrument is used for open surgery and hysteroscope Minimally Invasive Surgery.In hysteroscope Minimally Invasive SurgeryElectrosurgical instrument be gun type of gas burner.Wherein the Electrosurgical instrument of gun-type generally includes shell, knob, shaft, consolidatesDetermine actuating component, actuating mechanism, end effector (jaw), blade, switch.Electrosurgical instrument passes through connector and high frequencyGenerator is connected.Export high-frequency current by radio-frequency generator, electric current by the electrode that is separately positioned on two jaws toTissue provides high-frequency electrical energy, solidifies the tissue dewatering between two electrodes, to achieve the purpose that electric coagulation hemostasis.Wherein doctorIt is needed when being performed the operation constantly by the direction of rotation knob adjustment jaw to reach optimal surgical field of view and effect, stillJaw needs 2 electric wires and is connected to shell from jaw and then achievees the purpose that connect high-frequency apparatus, this 2 electricity in the prior artLine one end is fixed in jaw, and one end is fixed in shell, and just will drive vice jaw part when needing to rotate jawElectric wire rotate together, and the electric wire of shell ends be it is motionless, this results in line that can wind, and wire intertwist causes to break in order to preventThe shaft of the existing Electrosurgical instrument of the phenomenon that splitting is to cannot achieve 360 ° of flexible rotatings, can only turn 180 ° clockwise, andThis direction for resulting in quickly adjusting jaw in clinical use of 180 ° of rotation counterclockwise increases operating difficulty, extendsOperating time.
Summary of the invention
This programme technical problems to be solved are to provide a kind of electrosurgery rotating angle control device, realize electro-surgical deviceThe flexible rotating of shaft makes the quick adjustment direction of jaw, to reduce operating difficulty, reduces operating time.
In order to solve the above technical problems, the electrosurgery rotating angle control device of this programme includes shaft, including head end andEnd；Knob is fixedly connected to drive the shaft to rotate with the head end of the shaft；Jaw is arranged in the shaft end；Live wire is set in the jaw；Shell wire connections are fixed at the shell of the electrosurgery rotating angle control deviceOn；The shell wire connections include shell line conductive part and shell line insulation division；Jaw wire connections are fixed at describedOn the shaft of electrosurgery rotating angle control device；The jaw wire connections include jaw line conductive part and the insulation of jaw linePortion；The shell line conductive part matches conducting with the jaw line conductive part.
Preferably, the shell wire connections are two beckets being integrated with plastic injection, and two beckets are notIt is in contact.
Preferably, the shell wire connections thermoplastic is on the housing.
Preferably, the jaw wire connections are two beckets being integrated with plastic injection, and two beckets are notIt is in contact.
Preferably, the jaw wire connections thermoplastic is on the shaft.
Preferably, the knob is fixedly connected with shaft by encapsulated injection molding manner.
Preferably, the knob is fixedly connected by way of gluing or ultrasonic welding with shaft.
Detailed description of the invention
Fig. 1-3 is the electro-surgical device schematic diagram in electrosurgery rotating angle control device of the invention.
Specific embodiment
Present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring initially to Fig. 1, electro-surgical device 10 includes elongated shaft 120, with head end 120a and end 120b." head end " refers to that one end of the closer user of electro-surgical device 10, " end " refer to one end further away from user.InstituteThe end 120b connection jaw 110 for the shaft 120 stated.The head end 120a connection knob 130 and shell 140 of the shaft 120.The knob 130 is able to drive the rotation of shaft 120, and then rotates with movable clamp port.The knob 130 shaft with shown in120 are fixed together by encapsulated injection molding, gluing, ultrasonic welding etc. mode.
As Figure 2-3, a jaw wire connections 121 are fixed on shaft 120, jaw wire connections can be 2Becket is integrated with plastic injection, and 2 are not in contact, this 2 beckets are respectively intended to 2 electric wires of connection jaw.A shell wire connections 201 are fixed on shell, shell wire connections 141 can be 2 beckets, be one with plastic injectionBody, and 2 are not in contact, this 2 beckets are respectively intended to 2 electric wires of connection shell.And 2 in housing connection member 2012 beckets of a becket and jaw connector contact conducting one by one.It can band when rotating knob 130, shaft 120 is rotatedMovable clamp port wire connections 121 rotate together, and housing connection member is fixed on motionless on shell, and no matter how knob revolves in this wayTurn the phenomenon that line does not have winding, is achieved that 360 ° of jaw any rotations.
The present invention has been described in detail through specific embodiments, which is only of the invention preferableEmbodiment, the invention is not limited to above embodiment.Without departing from the principles of the present invention, those skilled in the artThe equivalent replacement and improvement that member makes shape, structure, the material etc. of Electrosurgical forceps, are regarded as the skill protected in the present inventionIn art scope.
