[ background art ]

Now, the electrotome has been very frequently in medical treatment use, and the electrotome is when cutting tissue or electric coagulation hemostasis, and the other liquid of electrotome can influence the normal work of electrotome, often needs the second operator to use the aspirator to eliminate liquid this moment, and the thick heaviness of additional suction mouth of pipe, influences operation progress and visual field and exposes, and because the suction mouth of pipe is far away from the electrotome head, can't be close to the suction to narrow and small regional suction mouth of pipe, can not suck whole smog, especially to the processing of complicated adhesion pathological change especially difficult.

In the conventional operative lung lobe resection process of lung cancer, pulmonary tuberculosis, pulmonary nodules and other diseases, pulmonary blood vessels of some people are clearly dissected, well-divided, free from adhesion with pleura, easy to dissociate the phylum, simple and easy to perform lung lobe resection, and can be performed under a complete endoscope. Some lung lesions are difficult to remove due to adhesion, calcification of lymph nodes, incomplete lobulation and other factors. Similarly, intestinal and gynecological tumors, etc. also face the same problem. In the past, the blunt and sharp free blood vessels can be realized by opening the chest or opening the abdomen with fingers, an aspirator head, a right-angle clamp and the like under an open incision or an endoscope.

Especially for severe lung diseases or abdominal cavity and pelvic cavity diseases, the operation is extremely difficult to complete under an endoscope, an ultrasonic knife cannot be used, and sometimes a blood vessel or adjacent organs are easy to be damaged by an electric hook, even a massive hemorrhage and death are caused. The ultrasonic knife and the electric hook can not be used for operations with serious adhesion because the ultrasonic knife and the electric hook can not be used for 'blunt + sharp' dissociation. Therefore, an instrument which can integrally realize 'blunt + sharp' free blood vessels is needed to be needed.
