Bracket type vascular anastomosis device

Abstract

The invention relates to the field of medical equipment and particularly relates to a bracket type vascular anastomosis device. The bracket type vascular anastomosis device comprises a film laminating bracket; the film laminating bracket comprises an inner-layer laminating film, a metal bracket and an outer-layer laminating film; the whole body of the metal bracket is cylindrical; the inner-layer laminating film and the outer-layer laminating film are lined on an inner side and an outer side of the metal bracket respectively; the bracket type vascular anastomosis device further comprises a conveyor and the conveyor comprises a balloon, a connecting hose and a connector, which are communicated in sequence; the metal bracket is formed by knitting a cobalt-chromium alloy wire or a NiTi shape memory alloy wire; the balloon is a non-compliance balloon; the balloon is arranged in the film laminating bracket. The bracket type vascular anastomosis device is suitable for carrying out vascular anastomosis on deep tissues with relatively narrow spaces; the vascular anastomosis time can be shortened; vascular intimal hyperplasia can be reduced to the greatest extent and a narrow anastomosis hole is avoided; after the anastomosis, a blood vessel can be retracted and relaxed in a certain extent along blood pressure and physiological demands are met; the blood vessel can be prevented from slipping off from the film laminating bracket and the bracket type vascular anastomosis device is very reliable.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a stent type blood vessel anastomosis device. Background technique [0002] With the development of clinical surgery, more and more vascular anastomosis operations are performed in various operations. The various operations mentioned here include not only vascular anastomosis performed in conventional operations such as vascular surgery and cardiac surgery, but also general surgery and urological surgery. Reconstruction of blood vessels involved in extended tumor resection, as well as vascular reconstruction of various solid organ transplants. [0003] However, the traditional vascular anastomosis method with prolene suture is complicated to operate and takes a long time to anastomose, which prolongs the ischemia time of distal tissues and organs, affects the blood flow rate of the anastomosis, and seriously damages the intima. [0004] Mechanical vascular anastomosis is a vas...

Problems solved by technology

According to the accompanying drawings 38 and 39 of CN00130855, it can be seen that when the blood vessel cavity is inserted into the host blood vessel, a certain space is required between the two sections of blood vessels to allow the supply vessel cavity to be inserted into the host blood vessel; During vascular anastomosis, due to insufficient space, it is also difficult to achieve vascular anastomosis with this artificial blood vessel
