Problems solved by technology

[0003] However, at present, the insulator is embedded in the upper clamp rod in the clamp head of the bipolar electrocoagulation forceps, and a mounting hole is penetrated on the upper clamp rod and the insulator inside, and the lower clamp rod is fixed with a ceramic pin , and the ceramic pin is passed through the mounting hole on the upper clamping rod and its inner insulating part, and can rotate in the mounting hole, and since there is a gap between the ceramic pin and the mounting hole, and the upper clamping rod is a conductor, The lower clamping rod is also a conductor, so it is easy to generate a space discharge problem between the upper clamping rod and the lower clamping rod through the gap between the ceramic pin and the mounting hole. At the same time, one of the clamp heads of the existing bipolar electrocoagulation forceps The clamping rod is hinged with an electrically conductive mounting base, but the mounting base has a cavity near the clamping rod, and since the tail end of the clamping rod will extend into the cavity to connect with the conductive core , it will easily lead to the problem of high-frequency discharge in the cavity, so there is a big safety hazard in the work of the bipolar coagulation forceps in the prior art in the environment of the liquid in the peritoneal cavity of the human body
[0004] Moreover, since the insulator of the clamp head of the bipolar electrocoagulation forceps in the prior art is embedded in the upper clamping rod, the insulating part is easy to float in the upper clamping rod, resulting in the bipolar electrocoagulation forceps in the prior art The pincer head of the bipolar electric coagulation forceps is not firm, and the pin used to make the two pincer bars hinged in the prior art is a ceramic pin, which is easy to break. Therefore, the pincer head of the bipolar electrocoagulation forceps in the prior art is easily damaged, and the service life is longer short

Abstract

A first forceps holder rod is integrally connected by an insulating part and a metal forceps holder rod provided with a through hole in a penetrating manner, a first mounting hole coaxially distributed with the through hole is formed in the position, corresponding to the through hole, of the insulating part in a penetrating manner, and the hole wall of the through hole is coated with the hole wall of the first mounting hole; a first pin shaft is fixed at the tail end of the second forceps holder rod, is arranged in the first mounting hole in a penetrating manner and can rotate in the first mounting hole; a first U-shaped slot is formed in the head end of the conductive fork piece, and the two side walls of the first U-shaped slot are hinged to the tail end of the second forceps holder rod; the insulating fork piece is connected in the first U-shaped slot, the head end of the insulating fork piece is provided with a second U-shaped slot, and the tail end of the insulating piece can respectively define an insulating space with two side walls of the second U-shaped slot and the slot bottom of the second U-shaped slot. According to the clamp head of the bipolar electrocoagulation clamp, space discharge is not prone to being generated, so that the safety performance of the clamp head is improved, and meanwhile the service life of the clamp head is prolonged.

Description

technical field [0001] The invention relates to the technical field of surgical forceps for medical instruments, in particular to a forceps head of a bipolar electrocoagulation forceps. Background technique [0002] Electrocoagulation forceps are a kind of commonly used medical equipment, which are mostly used in brain surgery, microsurgery, ENT, obstetrics and gynecology and hand surgery. Electrocoagulation for hemostasis by bipolar conduction. The application method is: providing high-frequency electric energy to the body tissue through the two tips of the bipolar, so that the tissue between the two ends of the bipolar is dehydrated and coagulated, so as to achieve the purpose of hemostasis. [0003] However, at present, the insulator is embedded in the upper clamp rod in the clamp head of the bipolar coagulation forceps, and the upper clamp rod and the insulator in it are provided with installation holes, and the lower clamp rod is fixed with a ceramic pin. , and the ce...
