Casing pipe rotating shaft type bipolar electrocoagulator

Abstract

The invention belongs to medical instruments used for surgical hemostasis and provides a casing pipe rotating shaft type bipolar electrocoagulator. The bipolar electrocoagulator comprises an electric connector, an electrode handle and a working electrode; a connecting rod between the electrode handle and the working electrode is composed of an inner casing pipe and an outer casing pipe which can axially rotate relative to each other; an insulating layer is arranged between the inner casing pipe and the outer casing pipe, one end of the inner casing pipe and one end of the outer casing pipe are connected with the working electrode separately, and certain included angles are formed between the inner casing pipe and the working electrode and between the outer casing pipe and the working electrode; the working electrode is opened or closed when the inner casing pipe and the outer casing pipe axially rotate relative to each other. The casing pipe rotating shaft type bipolar electrocoagulator can be connected with a high-frequency electric knife, a bipolar electrocoagulator and a host of a radio-frequency or low-temperature plasma radio-frequency surgery system in an operating room through wire plugs or adapters, the structure is simple and durable, and the hemostatic effect is good. The inner casing pipe and the outer casing pipe can be connected with a water dropping tube and a suction tube respectively, so that the bipolar electrocoagulator has the water dripping, adhesion prevention and suction functions. The casing pipe rotating shaft type bipolar electrocoagulator is made of medical-grade non-toxic and high-temperature-resistant materials, and can be repeatedly disinfected or disposable.

Description

technical field [0001] The invention belongs to a medical instrument for assisting hemostasis in surgical operations. Background technique [0002] Bipolar coagulation is a commonly used method of hemostasis in surgical operations. It has the advantages of safety and reliability, and is suitable for various surgical applications. But there are also some disadvantages, such as the working electrode of electrocoagulation is prone to eschar adhesion. Conventional electrocoagulation forceps are relatively large, and it is difficult to enter the small and deep surgical field for operation. The structure of electrocoagulation forceps is relatively complicated, and the movable joints of its electrocoagulation end and handle end are all extremely easy to damage. Various bipolar electric coagulation forceps or electric coagulation forceps that have been commercialized and put into clinical application are large in volume or diameter at present, and lack models and specifications th...
