Anastomosis cannula for rapid connection of rat vein replacement

Abstract

The invention discloses an anastomosis cannula for rapid connection of rat vein replacement. The anastomosis cannula comprises a quick-connection anastomosis cannula body, an outer sleeve, a sliding groove, a sliding block, a movable sleeve, an insertion block, a cavity, a limiting shaft, an inner sleeve, a through hole, a limiting groove, a connecting pipe, a sealing ring, a limiting block, a fixed block, a sealing gasket, an open hole, an end, a vertical hole, a connector, a sealing cover, a sealing ring, an insertion groove, a limiting sleeve, an extrusion block, an outer threaded pipe, an inner threaded pipe and a sealing cover. The anastomosis cannula for rapid connection of rat vein replacement has the advantages that the structure is reasonable and reliable, rapid connection is convenient, connection of blood vessels is achieved through the cannula, connection between the blood vessels and the cannula is achieved through generated extrusion force, the operation time is shortened, rapid connection of the cannula is convenient, the operation difficulty of an operation is reduced, connection stability is guaranteed, replacement and disassembly are easy and fast, and connection of the tail end of the vein vessel or connection of the disconnected position of the vein vessel can be achieved through mutual butt joint of two sections of sleeves.

Description

technical field [0001] The invention relates to a quick-connected anastomotic sleeve, in particular to a quick-connected anastomotic sleeve for rat vein replacement, and belongs to the technical field of anastomotic sleeve applications. Background technique [0002] Anastomotic sleeve is a connecting sleeve used for venous anastomosis. Its function is to connect venous blood vessels. It is connected with an anastomat. In medicine, anastomosis refers to the process of connecting two fractured surfaces of an organ. The application of the method is obvious. The microsurgical vascular anastomosis sleeve anastomoses blood vessels. When anastomosing blood vessels, the blood vessel is inserted into the inner cavity of the sleeve through the longitudinal gap on the surface of the sleeve, and the wall of the broken end of the blood vessel is turned over and placed outside the end of the sleeve, and then the other end of the blood vessel is placed on the outside of the sleeve. On the ...

Problems solved by technology

[0004] In order to solve the deficiencies of the prior art, this application adopts multi-stage sleeves for the connection of blood vessels, which has the advantage of fast connection, can be stably docked with blood vessels after connection, can realize quick disassembly of sleeves, and is easy to operate and reduce the difficulty of surgery, solving the problem of using The long operation time is caused by the connection of staples, and it is also difficult to remove the cannula
