Novel vascular anastomosis device for vascular surgery

Abstract

The invention discloses a novel vascular anastomosis device for vascular surgery, which structurally comprises a handle, a torsional spring, a fastening plate, a suture plate, fastening rods and fastening sleeves. By arrangement of an anti-slip fastener structure, a blood vessel penetrating the suture plate can be clamped to avoid bleeding caused by blood flowing in suture; by magnetic fastening functions of a positive magnetic plate and a negative magnetic plate, the blood vessel is steadily clamped without damages of the blood vessel due to rubber sleeves for surface sleeving, and medical personnel can be assisted in quick suture of the blood vessel. In adoption of a pressure suction structure for overlapping suture of the fastened blood vessel, the blood vessel shifts in overlapping dueto own characteristics, splitting of joints is avoided, the blood vessel is fixed through negative-pressure suction while sleeving is realized, and accordingly overlapping suture of the blood sutureis realized, and slipping is prevented.

Description

technical field [0001] The invention relates to the medical field, more precisely, it is a novel vascular anastomosis device for vascular surgery. Background technique [0002] Blood vessels are the channels through which blood flows, and because there are many blood vessels of different diameters distributed on the surface of human bones, the rupture of blood vessels will cause massive bleeding when injured, so it is often necessary to perform anastomosis of blood vessels in surgical operations , in view of the characteristics of blood vessels, in the process of vascular anastomosis, it is often necessary to perform vascular anastomosis with the help of a microscope. In the vascular anastomosis operation, the doctor needs to perform at least 3 blood vessel anastomoses and the suturing time is more than 2 hours. Therefore, in the current In some medical equipment, the vascular anastomosis device is helpful to assist the doctor in suturing blood vessels. However, in the proce...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a novel vascular anastomosis device for vascular surgery to solve the problem in the prior art that the blood vessel itself is in the shape of a mucous membrane during the suturing process with the aid of the vascular anastomosis device. When the two vessels are anastomosed with the aid of a vascular anastomosis device, it is relatively slippery, resulting in a leaky joint. At the same time, when the two vessels are anastomosed with the help of a vascular anastomosis device, the overlap is slightly shifted due to the stick-slip effect of the blood vessels during the overlapping. Or there is a defect that the suture falls off and displaces, which leads to blood collapse in the sutured blood vessel
