Cut too deep, it is easy to cause bleeding; for general practitioners or doctors who are not skilled enough, the cutting of skin incision surgery is more troublesome; in abdominal surgery, it is usually necessary to open a specific small mouth in the cortex ( 3mm, 5mm, 10mm, 12mm), then insert using a three-sided blunt, and the trocar (trocar) passes through the skin into the abdominal cavity.
因此，现有技术还有待于改进和发展。 Therefore, the prior art has yet to be improved and developed.
