Disposable electrocoagulator with smoke exhaust function

Abstract

The invention discloses a disposable electrocoagulator with a smoke exhaust function. The electrocoagulator comprises a clamp clip, a pull rod, a clamp rod, a rotating wheel, a fixed handle and a movable handle; a pull rod connecting seat and a clamp rod connecting seat which are respectively connected to conducting wires are fixed in the fixed handle; the clamp rod is inserted into the rotating wheel and connected to the clamp rod connecting seat, and the pull rod penetrates out of the rotating wheel and is connected to the pull rod connecting seat and fixed on a pull rod seat on the movablehandle; the clamp rod connecting seat consists of a fixed outer sleeve, a rotating sleeve and a positioning pin, wherein the positioning pin is inserted into the clamp rod through the rotating wheel,the rotating sleeve fixedly sleeves the outer end of the positioning pin, and the rotating sleeve is rotatably arranged in the fixed outer sleeve; a smoke exhaust channel is reserved between the clamprod and the pull rod, a plurality of air inlet holes are formed at the position of the clamp rod close to the clamp clip, the clamp clip is provided with an air outlet hole close to the rotating wheel, a hole seat is arranged above the air outlet hole and sealed with the clamp rod, and the hole seat is provided with an installation hole connected to the air outlet hole; and a sealing ring sleeving the outside of the pull rod is arranged between the inner end of the clamp rod and the groove surface of the rotating wheel in a squeezing mode.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable electrocoagulation device with smoke exhaust function. Background technique [0002] Laparoscopy is the most commonly used surgical approach in modern medicine. Various energy devices are the basis of laparoscopic surgery. Among them, bipolar coagulation forceps is the most commonly used hemostatic energy device in laparoscopic surgery. The working principle of bipolar coagulation is to apply high-frequency current, safely pass through the human body, without causing nerve or muscle reaction, and use the thermal effect of high-frequency current to dehydrate and shrink the blood vessel wall, coagulate the blood in the blood vessel, and make the blood vessel and blood clot Integrate with each other to achieve the purpose of effective hemostasis. Bipolar electric coagulation forceps have exact hemostatic effect, are easy to use, have less rebleeding after operation, ...
