Technical Field

The invention belongs to the technical field of auxiliary instruments, and particularly relates to an auxiliary instrument for gastrointestinal operations in general surgery.

Background

The general surgery department is a clinical subject which mainly treats other diseases such as tumors and traumas of liver, biliary tract, pancreas, stomach and intestine, anorectum, vascular diseases, thyroid and breast, is the largest special subject of a surgical system, and is the general surgery department, general comprehensive hospital surgery department, orthopaedics, neurosurgery, cardiothoracic surgery, urinary surgery and the like besides the general surgery department, some hospitals even divide the general surgery department into neck-breast department, stomach and intestine department, hepatobiliary pancreas and spleen department and the like, anorectal department, burn plastic department, vascular surgery, pediatric surgery, transplantation surgery, nutrition department and the like which are related to the general surgery department, and the general surgery department can use some auxiliary instruments to help the gastrointestinal surgery or other operations to be better carried out, wherein the operation forceps comprise the operation forceps for the gastrointestinal surgery of the general surgery department, while the operation forceps for the gastrointestinal department of the existing general surgery department have no more adjustability in the using process, can not carry out corresponding change adjustment according to the actual operation of operation, the structure of integral type makes its use comparatively single for department of general surgery for the stomach operation forceps have certain restrictive when using.
