Abstract
A surgical stapler includes an anvil and a cartridge that cooperate with each other, a handle, and a connecting tube for connecting the cartridge to the handle. A stent mounting rod is arranged at a front end of the anvil, and a stent for distracting an orifice is movably connected to the stent mounting rod. The stent has a flexible and deformable tubular structure and can distract a lumen of the human orifice after a radial constraint is removed. The stent is coated with an anti-leakage film. An anti-reflux film is further arranged on the stent. The surgical stapler can effectively solve some complications after anastomosis by an existing surgical stapler, and can be widely used in the technical field of medical anastomosis.
