Problems solved by technology

[0005] The problem to be solved by the present invention is the gun-type high-frequency electrosurgical instrument in the prior art. Since the gun barrel adopts the superimposed structure of the inner push rod, the inner sleeve and the outer sleeve, the space in the gun barrel is narrow and the size of the parts in the gun barrel is small. Design constraints resulting in reduced part strength and reduced instrument life

Abstract

The invention discloses a high-frequency electric surgical operating instrument. The high-frequency electric surgical operating instrument comprises a handheld component which comprises a trigger unit and is used for generating driving, a connection rod which extends from the handheld component to the far end, and a clamping device which is arranged at the far end of the connection rod and is used for clamping a tissue, wherein the connection rod comprises an outer sleeve, a pull rod and a tool push rod; the near end of the outer sleeve is connected with the far end of the handheld component; the far end of the outer sleeve is connected with the clamping device; the pull rod is arranged in the outer sleeve and is of a platy structure; the trigger unit drives the pull rod to move so as to further control the clamping device to be opened and closed; the tool push rod and the pull rod are arranged side by side; a cutter is arranged at the far end of the tool push rod. As the pull rod is of the platy structure which replaces the sleeve structure in the prior art, and the tool push rod and the pull rod are arranged in the outer sleeve side by side, the space in a gun tube is saved; the pull rod is of the platy structure which enhances the part intensity, so that the service lives of the parts such as the pull rod are prolonged, and the fault rate of the electric surgical operating instrument is reduced.

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 ...
