cutting stapler

Abstract

The invention provides a cutting anastomat. The cutting anastomat comprises an anastomat body, a nail anvil assembly, a nail tube connected with the anastomat body and a nail anvil pull rod which can extend outside the end face of the nail tube, wherein the nail anvil pull rod is selectively connected with the nail anvil assembly, the nail anvil pull rod comprises a flexible part which is at least partially contained in the nail tube and a connecting part which is arranged at the far end of the flexible part, and the connecting part is connected with the nail anvil assembly in a dismounting manner. The cutting anastomat has the advantages that the nail anvil pull rod is easy to bend, a bending angle can be regulated at random, flexibility is good, the requirement of a small operation space can be met, or the cutting anastomat can bypass human tissues which stop the cutting anastomat from moving ahead, and anastomosis during operation can be smoothly completed.

Description

technical field [0001] The invention relates to a medical device, in particular to a cutting stapler. Background technique [0002] The round tube stapler is a medical device often used in surgical operations on physiological tissues such as the digestive tract. Most of this type of stapler adopts the axial inward binding method. During the anastomosis, the two sections of tissue are restrained, forming a circular anastomotic ring inside the tissue. This instrument can make the body hemorrhage generated during the operation be discharged together with the contents, and the body tissue after operation Easier to heal. [0003] Currently, a circular-tube stapler for treating hemorrhoids includes a stapler body, an operating handle movably connected to the stapler body, and an anvil assembly matched with the body. The stapler body includes an annular staple cartridge and a cutting knife arranged at the distal end. The anvil assembly includes a conical anvil, an anvil cap fixe...

AI Technical Summary

Problems solved by technology

[0004] In the existing operation process, if the anvil shaft of the cutting anastomat is to cooperate with the anvil pull rod, the body of the cutting stapler and the anvil shaft must be in a straight line, so that the anvil pull rod can be inserted into the anvil shaft , which can be easily realized in open surgery, but in the case of relatively narrow and cramped operating space, it is difficult to achieve

For example, in laparoscopic surgery or upper esophagus surgery, the body of the cutting stapler may block the doctor's sight, and the operation cannot be flexible, so the anvil pull rod is not easy to cooperate with the anvil shaft, and then give Inconvenience from surgery
