Abstract

The invention relates to a circular anastomat which is applicable to laparoscopic surgery and wide in view range under a laparoscope. The anastomat includes a nail abutting base, a cutting and matching assembly and a control lever; the size of the control lever is smaller than that of the laparoscope and can be inserted into the body of a patient through the laparoscope for operation; a connectionhead is arranged on the nail abutting base and penetrates through the cutting and matching assembly to be connected with the control lever; the cutting and matching assembly is connected with the control lever and comprises a nail bin, a nail pushing sheet and a shell; a cutter is arranged on the head part of the nail pushing sheet and fixed to the nail pushing sheet, the nail bin is fixedly connected to the shell, and the nail pushing sheet and the cutter can be moved and stretched out in the direction of the nail abutting base under driving of the control lever. The cutter cuts off target tissue, the nail pushing sheet pushes suturing nails in the nail bin to the end face of the nail abutting base, and the suturing nails are used for suturing the tissue.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a laparoscopic circular stapler which is suitable for laparoscopic surgery and is easy to operate and use. Background technique [0002] Stapler is a medical device used in medicine to replace traditional manual suturing. It has the advantages of convenient use, fast suturing, tight suturing, moderate elasticity, and fewer side effects and surgical complications. Circular stapler is a kind of stapler that is often used in surgical operations on physiological tissues such as the digestive tract. It adopts axial anastomosis and forms a circular anastomotic ring inside the tissue. The postoperative tissue is easy to heal and the pain of the patient is relieved. [0003] The current circular stapler adopts a combined structure of an anvil and a stapler body, and the size of the body is relatively large, which is suitable for use in a traditional open surgical environment. ...
