Background

Laparoscopes are endoscopes used for abdominal or posterior abdominal examination and treatment, which are the direction of surgical development today, and almost all abdominal surgery can be performed using laparoscopes. The laparoscopic surgery is an epoch-spanning progress of the traditional open surgery and has the advantages of small surgical wound, quick postoperative recovery, short hospitalization time, light postoperative pain and attractive abdominal incision.

Laparoscopic surgery, especially liver and pancreas surgery, needs to use limited instruments to accurately complete operations such as separation, electrocoagulation, ligation and the like in a narrow space, so that multifunctional instruments are needed to complete the operations, repeated instrument replacement is avoided, and the operation efficiency is improved. Electrosurgery plays a great role in laparoscopic surgery, particularly in liver and pancreas surgery. The combination of laparoscopic instruments and electrosurgery that can efficiently perform the processes of separating, pushing, jacking, pressing, picking, stripping, clamping, etc., as well as hemostasis and coagulation is the basis of laparoscopic surgery. In laparoscopic surgery, the forceps are widely used for fine dissection and electric coagulation, and play an extremely important role in laparoscopic liver and pancreas surgery. The laparoscopic liver and pancreas operation has narrow operation space, the surrounding important blood vessels are densely distributed, and the separation forceps can effectively separate and accurately perform electric coagulation. Can realize the electrocoagulation effect without directly contacting bleeding spots, and is widely applied to surface bleeding of various visceral organs, particularly liver fracture surfaces. Thus the ability to perform both spray electrocoagulation and electro coagulation of clamped tissue is very important to the design of the forceps head. Therefore, when the electrocoagulation operation with higher precision requirement is carried out in a narrow space, the instruments are often required to be replaced, so that the multifunctional endoscopic separation forceps which can be used for completing separation, pushing, jacking, pressing, picking, stripping, clamping and the like under the endoscope and has the functions of stopping bleeding and coagulating blood are needed to be provided.
