Problems solved by technology

[0004] However, there are still many shortcomings in its actual use. For example, when the blood vessel is nested on the inner tube, the blood vessel is relatively narrow and infiltrated by blood, which makes it difficult and time-consuming to nest the blood vessel. Thus affecting the later fixed speed

Abstract

The invention discloses a vascular anastomosis device for vascular surgery, specifically relates to the technical field of medical equipment, comprising an outer tube, the outer tube is provided with a blood vessel nesting mechanism; the blood vessel nesting mechanism includes a fixed inner tube, the fixed One end of the inner tube is provided with a spiral extension tube, the top of the fixed inner tube is fixed with a top plate, the outer side of the top plate is provided with a positioning ring, the surface of the outer tube is provided with a through hole, and the inner wall of the through hole is provided with a positioning groove, so The positioning ring is slidably connected with the positioning groove, the other end of the fixed inner tube is fixed with a first air bag, the fixed inner tube and the top plate are both provided with a delivery air tube, and one end of the delivery air tube is provided with a second air bag. By setting the blood vessel nesting mechanism, the present invention can quickly nest the blood vessels in the fixed inner tube, effectively solve the problem that the blood vessels are narrow and difficult to nest, reduce the difficulty of blood vessel nesting, and reduce the nesting time, thereby increasing the speed of blood vessel anastomosis .

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, the invention relates to a vascular anastomosis device for vascular surgery. Background technique [0002] Vascular anastomosis device refers to a device that connects blood vessels. In addition to arteries-capillaries-veins, blood vessels in the human body are connected between arteries and arteries, between veins and veins, and even between arteries and veins. They can be directly connected with each other to form vascular anastomosis, which can be divided into arterial anastomosis, venous anastomosis, arteriovenous anastomosis and collateral anastomosis. [0003] The utility model patent application publication number CN109480944A discloses a vascular anastomosis device for vascular surgery, which is composed of an outer tube and an inner tube, the inner tube is located inside the outer tube, and an engaging buckle is provided on the outer wall of the inner tub...
