Description

Double-pole electric coagulation separating forceps for open operation Technical Field The invention relates to the technical field of medical appliances, in particular to a bipolar coagulation separation forceps for open surgery. Background The operation forceps play a vital role in the operation, can play roles in separating tissues, clamping, pulling, stopping bleeding and the like, can adopt an energy instrument to separate, grab, coagulate and close blood vessel ends and the like in the open operation, are commonly used at present an ultrasonic knife and a high-frequency bipolar electric coagulation forceps, wherein the high-frequency bipolar electric coagulation forceps are divided into a endoscopic operation electric coagulation forceps and an open operation electric coagulation forceps according to different specific operations, the bipolar electric coagulation forceps provide high-frequency electric energy for body tissues through two conductive structures of the bipolar forceps heads, so that the tissue between the bipolar forceps heads is subjected to electric coagulation and blood vessel dehydration coagulation, the effect of stopping bleeding of the body tissues is achieved, the tissue electric coagulation range is limited between the bipolar forceps heads, the risk of side injury caused by dispersed energy is reduced to the greatest extent, and the operation forceps have the advantages of good hemostatic effect, small side injury and the like. In the open operation process, body tissues are often required to be subjected to electric coagulation and cutting, the open operation electric coagulation forceps have good tissue electric coagulation effect and are widely applied to open operations, however, at present, partial open operation electric coagulation forceps have single functions and only have the function of electric coagulation tissues, but do not have the function of tissue cutting and separating, for example, chinese patent publication No. CN214208477U discloses an anorectal surgery electric coagulation forceps which is an electric coagulation forceps for open operation of surgery, but only has the function of electric coagulation hemostasis of tissues in operation, and an electric coagulation forceps head can not cut and separate the electric coagulation tissues. Therefore, the problems of single function exist in the prior art of the partial open operation electric coagulation forceps, and in the use process of the open operation electric coagulation forceps without the tissue separation function, when the tissue after the electric coagulation is required to be cut and separated, an operator has to replace a surgical instrument to cut the tissue after the electric coagulation, the operation is more troublesome, the tissue separation process is more complicated, and the operation quality is affected. Disclosure of Invention The bipolar coagulation separation forceps for the open operation are simple to operate, good in tissue coagulation effect, capable of effectively cutting and separating the coagulated tissues, capable of enabling operators to finish tissue coagulation separation operation without replacing other surgical instruments in the operation process, and capable of improving operation efficiency in the operation. The bipolar electrocoagulation separation forceps for the open surgery comprise a handle portion, wherein the front end of the handle portion is connected with an electrocoagulation forceps head, the electrocoagulation forceps head comprises a first forceps head and a second forceps head which are movably connected in a scissor shape, the handle portion comprises a first handle connected with the first forceps head and a second handle connected with the second forceps head, a blade control mechanism and a blade assembly are arranged in the first handle, the blade pushing mechanism is connected with the blade assembly, one end of the blade assembly is located in the first handle, the other end of the blade assembly is located in the electrocoagulation forceps head, a forceps head connecting wire electrically connected with the first forceps head and the second forceps head is arranged in the second handle, and the electrocoagulation forceps head is used for closing and clamping tissues and carrying out electrocoagulation on the tissues so as to cause the tissues to be electrocoagulation. The blade control mechanism comprises an inner fixed plate, a cutting control assembly, a pushing assembly and a spring, wherein the pushing assembly and the spring are arranged above the inner fixed plate, the cutting control assembly is connected with the pushing assembly, the pushing assembly is connected with the blade assembly, one end of the spring is connected with the pushing assembly, the other end of the spring is connected with the inner fixed plate, and after the electric coagulation forceps head is used for clamping electric coagulation tissues in a closed mode, the bl
