Novel vascular anastomotic device for vascular surgery

Abstract

The invention discloses a novel vascular anastomotic device for muscular surgery and particularly relates to the technical field of medical equipment. The novel vascular anastomotic device for muscular surgery comprises an outer tube; a vascular embedding mechanism is arranged inside the outer tube and comprises a fixing inner tube; one end of the fixing inner tube is provided with a spiral extended tube; a top plate is fixed to the top of the fixing inner tube; a positioning ring is arranged at the outer side of the top plate; the surface of the outer tube is provided with a through hole; theinner wall of the through hole is provided with a positioning groove; the positioning ring is in slidable connection with the positioning groove; a first balloon is fixed to the outer side of the other end of the fixing inner tube; the inside of each of the fixing inner tube and the top plate is provided with an air delivery tube; one end of each air delivery tube is provided with a second balloon. The vascular embedding mechanism is provided herein such that a vessel can be embedded in the fixing inner tube quickly; the problem that a narrow vessel is difficult to embed is solved effectively; vessel embedding difficulty is decreased; embedding time is shortened; vascular anastomotic speed is increased accordingly.

Description

technical field [0001] The invention relates to the technical field of medical equipment, and more specifically, the invention relates to a novel 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 of patent application publication number CN109480944A discloses a new type of vascular anastomosis device for vascular surgery, which is composed of an outer tube and an inner tube. buckle, the inner tube is fixedly connected to the inner wall of the outer tube through t...

AI Technical Summary

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
