High Frequency Electrosurgical Instruments

Abstract

The invention provides a high-frequency electrosurgery operating instrument. The high-frequency electrosurgery operating instrument comprises a handheld component, a connecting rod and a clamping device, wherein the handheld component comprises a trigger unit including a clamping trigger and a push-type broach trigger which are used for producing driving, the connecting rod extends towards the far end from the handheld component, and the clamping device is arranged at the far end of the connecting rod and used for clamping tissue. The high-frequency electrosurgery operating instrument further comprises a safety device, the safety device is arranged in the handheld component and connected with the trigger unit, and the safety device is suitable for controlling the push-type broach trigger according to the position of the clamping trigger. By means of the safety device, mistaken cutting, excessive cutting and other bad phenomena caused by mistaken operation of triggering the push-type broach trigger of the user before a gripping mechanism is closed completely in the surgery process are avoided. It is guaranteed that the user cannot trigger the push-type broach trigger until the gripping mechanism is closed completely to finish the cutting action on the instruction structure, and safety and effectiveness of the surgery are ensured.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a high-frequency electrosurgical instrument. Background technique [0002] High-frequency electrosurgical instruments are surgical instruments used for electrocoagulation to stop bleeding and / or cut tissue during surgery, and have been widely used clinically. At present, high-frequency electrosurgical instruments can be used not only in open surgery, but also in laparoscopy and other laparoscopy. High-frequency electrosurgical instruments usually include gun-type and forceps-type structures, and the high-frequency electrosurgical instruments with gun-type structure usually include clamps and handles with electrodes. The high-frequency electrosurgical instrument is further connected with a high-frequency generator and a foot switch through connecting wires. High-frequency current is output through the high-frequency generator, and the current provides high-frequency electric ...

AI Technical Summary

Problems solved by technology

[0005] The problem to be solved by the present invention is that the gun-type high-frequency electrosurgical instrument in the prior art is used for miscutting, multi-cutting and other undesirable phenomena, and because the gun barrel adopts an inner push rod, an inner sleeve and an outer sleeve to overlap The structure of the barrel leads to a narrow space in the barrel, and the size design of the parts in the barrel is limited, resulting in a reduction in the strength of the parts and a decrease in the service life of the instrument
