Embodiment Construction

[0007] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0008] refer to figure 1 , figure 2 and image 3 As shown, a casing rotating shaft bipolar coagulation composed of an electric connector, an electrode handle and a working electrode is characterized in that: the connecting rod between the electrode handle and the working electrode adopts an inner casing 3 that can rotate axially with each other Composed of an outer sleeve 4, an insulating layer 5 is provided between the inner sleeve 3 and the outer sleeve 4, one end of the inner sleeve 3 and the outer sleeve 4 are respectively connected to the working electrode 1, 2, and the other end is connected to the electrical connector 11 through the handle 8 connect. The inner sleeve 3 and the outer sleeve 4 form a certain angle with the respectively connected working electrodes 1 and 2. When the inner sleeve 3 and the outer s...

Abstract

It belongs to a medical device used for hemostasis in surgery. It is composed of an electric connector, an electrode handle and a working electrode. The connecting rod between the electrode handle and the working electrode is composed of an inner sleeve and an outer sleeve that can rotate axially. There is an insulating layer between the tube and the outer tube. One end of the inner tube and the outer tube are respectively connected to the working electrode and form a certain angle. When the inner tube and the outer tube rotate axially, the working electrode opens or closes. . The cannula-rotating bipolar coagulation can be connected to the main unit of the operating room high-frequency electrosurgical unit, bipolar coagulation, radio frequency or low-temperature plasma radio frequency surgical system through wire plugs or adapters. The structure is simple and durable and has a good hemostasis effect. The inner casing and the outer casing can also be respectively connected with drip pipes and suction pipes, which have functions of anti-adhesion and suction of dripping water. The cannula rotating shaft bipolar electrocoagulation is made of medical-grade non-toxic and high-temperature-resistant materials, which can be used for repeated disinfection or one-time use.

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...
