Background

A high frequency electric hook is an electrosurgical instrument that replaces a mechanical surgical hook for tissue cutting. The tissue is heated when the high-frequency high-voltage current generated by the tip of the effective electrode contacts with the body, so that the separation and coagulation of the body tissue are realized, and the purposes of cutting and hemostasis are achieved. The existing high-frequency electric hook control switch has two types of foot control and hand control, wherein the foot control is to arrange the switch on the ground and control the electric hook by stepping on the switch with the foot, so that a doctor focuses on the hook head of the high-frequency electric hook during operation and cannot see the foot control switch, the use is inconvenient, and the switch is carelessly stepped on during the operation, so that potential safety hazards exist; the manual switch is arranged on one side of the handle, when the doctor pinches the electric hook handle, the switch is not positioned at the forefinger and thumb, the electric hook is rotated according to the switch requirement, the electric hook is moved due to the electric hook rotation, the cutting position is changed, and the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned problem, designed a thoracoscope surgery high frequency electric hook, this high frequency electric hook adopts manual switch control, need not rotate the electric hook when pressing the switch, all can control the electric hook in which direction, and it is very convenient to use.

In order to realize the technical purpose, reach above-mentioned technological effect, the utility model discloses a realize through following technical scheme:

a high-frequency electric hook for thoracoscope surgery comprises a plug, a lead, a handle, a switch and an electric hook. The plug is connected with a handle through a wire, the handle is cylindrical, the front end of the handle is connected with an electric hook, two switches are arranged on the handle, one switch is an electric cutting switch, the other switch is an electric coagulation switch, the switches are annular, the switches can be pressed in any direction, the annular switch comprises an insulating shell and a copper sheet, the axial section of the insulating shell is in an outward convex arc shape, the insulating shell surrounds the periphery of the handle, the copper sheet is in an annular shape, the copper sheet is provided with two layers, the inner layer is fixed on the periphery of the handle, and the outer layer is fixed on the top of an inner side arc of the insulating shell; the insulating shell has elasticity, and the outer inward deformation of copper sheet contacts with the copper sheet inlayer when pressing, and the switch on power, hand are released and are not pressed, and the insulating shell drives the outer original shape that resumes of copper sheet, switch off.

Further, insulating casing adopt the rubber material, elasticity is good, insulating nature is good, convex shell, the circular arc top can outwards be bounced, has increased insulating casing elastic deformation and has resumeed, can effectively break off the switch, the insulating casing colour of two switches different, the insulating casing of electrotomy switch is blue, the insulating casing of electrocoagulation switch is yellow.

The utility model has the advantages that: the device adopts annular switch, and annular switch is outwards protruding, and elastic deformation through insulating casing contacts and disconnect switch, and during the doctor's operation, no matter which position of pressing annular switch can both the switch on, need not change the electric hook again during the use, and it is very convenient to use.
