Guide piece and circular tube type anastomat

Abstract

The invention provides a guide piece and a circular tube type anastomat. The guide piece is used for guiding a nail bin assembly of the circular tube type anastomat to enter a surgical site. The guide piece comprises a first guide part and a second guide part, wherein the second guide part is detachably fixed to the far-end side of the nail bin assembly through the first guide part, and when the second guide part is subjected to external force in the direction towards the far-end side, the second guide part can move towards the far-end side to be separated from the nail bin assembly. According to the guide piece for the circular tube type anastomat, the guide piece is arranged on the far-end side of the nail bin assembly, the nail bin assembly can be well guided to enter the surgical part, after the nail bin assembly reaches the surgical position, external force in the direction towards the far-end side is applied to the guide piece, at least part of the guide piece can be conveniently removed from the far-end side, no extra burden is added to the surgical process, and the use experience is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a guide and a round tube stapler. Background technique [0002] In the prior art, a circular tubular stapler 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 a firing component and a staple cartridge component disposed on the distal side. During the operation, place the two pieces of tissue that need to be anastomosed between the anvil of the anvil assembly and the staple cartridge of the staple cartridge assembly, adjust the distance between the anvil and the staple cartridge to gradually clamp the tissue, and then drive it through the operating handle The firing component makes the staples form on the anvil to complete the anastomotic connection of the two sections of tissue. [0003] During the actual surgical operation, the body part of the circular tubular ...

AI Technical Summary

Problems solved by technology

Since the small intestine is in a disconnected state after resection of the diseased tissue during the operation, and the intestinal wall is in a state of sticking together, the nail barrel of the circular tubular stapler is not easy to enter the tubular tissue, and the inner wall of the digestive tract is the tissue mucosa, usually Circular staplers are easy to cause damage to the mucous membrane when passing through the small intestine
