Problems solved by technology

[0002] At present, the disposable circular stapler is not equipped with an automatic safety device, and the safety block will automatically open, resulting in false firing, resulting in the failure of the operation
At present, the anvils of disposable circular staplers are relatively thick, bulky, and difficult to insert into the intestinal tract
In addition, the existing disposable circular stapler nail cartridge sleeve and aluminum elbow are extruded, the connection surface is rough, and the tissue is easily scratched during the operation. During the process, the surgical operator is not easy to grasp, the resistance is relatively large, it is easy to slip, and the operation is not convenient enough
