Rope type vascular anastomosis device

Abstract

A rope type blood vessel anastomosis device comprises an operating handle, a connecting structure, a pulling device and anastomosis devices, the connecting structure is fixedly arranged on the operating handle, the pulling device is arranged on the connecting structure in a sliding mode, the anastomosis devices are movably connected with the pulling device, a connecting rod is arranged on the pulling device, the anastomosis devices are movably connected to the two sides of the connecting rod, the anastomosis device is connected with a pulling structure in the pulling device through a rope, and the pulling structure is connected with a driving structure in the operating handle through a pulling rod. The anastomosis device has the beneficial effect that the anastomosis can be stopped after the anastomosis degree of the anastomosis ring is determined. The problem that the final anastomosis state, namely the distance between the two anastomosis rings, is different due to different wall thicknesses of blood vessels even if the diameters of the blood vessels are the same in actual operation is solved. On the basis, the structures of the base and the sleeve of the anastomosis part are further improved, so that the blood vessel can be conveniently turned outwards to hang the needle after penetrating through the anastomosis ring.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically relates to a rope type 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 recove...

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
