Novel vascular anastomosis device

Abstract

The invention discloses a novel vascular anastomosis device. The novel vascular anastomosis device comprises two anastomosis rings; the two anastomosis rings are movably connected to a base; the base is inserted into connecting sleeves, and the two connecting sleeves are connected with a second connecting rod through a linkage rod; one end of a holding handle is connected with the second connecting rod, the other end of the holding handle is connected with a first connecting rod, and the tail end of the first connecting rod is connected with a sliding block in a screwing handle; a stroke rod is arranged on the outer side of the first connecting rod and the outer side of the second connecting rod; one end of the stroke rod is connected with the screwing handle, and the other end of the stroke rod penetrates through the holding handle and is connected with an ejector rod; and a reversing block is connected to the position, between the holding handle and the connecting sleeves, of the stroke rod. According to the anastomosis device, the convenience and stability during blood vessel anastomosis can be improved, so that the blood vessel reconstruction speed is increased, the blood flow of transplanted visceral organs is quickly recovered, the failure probability of blood vessel anastomosis is reduced, and complications are reduced.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a novel blood vessel anastomosis device. Background technique [0002] Organ transplantation is a complex procedure in which a healthy organ is transplanted into a patient's body to replace a patient's non-functional organ due to disease. With the continuous improvement of organ transplantation techniques and surgical treatment levels, the survival rate and quality of life of organ transplant patients have been significantly improved. Organ transplantation technology has become an effective means of treating various end-stage organ diseases. [0003] In liver and kidney transplantation, the most difficult and technically demanding part of new organ implantation after organ resection is the repair and reconstruction of the arteriovenous vessels on the donor viscera, which has decisive significance for the success rate of the operation and postoperative recovery...

AI Technical Summary

Problems solved by technology

For example, the receptors of the superior and inferior hepatic vena cava are difficult to lengthen and are easy to retract, and the diameter of the blood vessels ranges from 10 to 30 mm, which cannot be achieved with existing instruments

At present, the common method in the world is still manual continuous valgus suturing. Due to the narrow space, the operation is difficult, time-consuming and laborious. The average vascular reconstruction takes 35-60 minutes, resulting in a long anhepatic period during the operation, which has a great impact on the heart, lungs and other organs. Quality control is affected by doctors' skills, and complications such as postoperative bleeding and vascular interface stenosis are prone to occur, which is the most critical part of organ transplantation
