Chimeric combined vascular anastomosis device

Abstract

The invention discloses a chimeric combined vascular anastomosis device. The chimeric combined vascular anastomosis device comprises two parts, namely, an acceptor end and a donor end, the acceptor end and the donor end are of annular structures, the sizes of the acceptor end and the donor end are matched with blood vessels of the acceptor end and blood vessels of the donor end respectively, a chimeric mechanism is arranged on the acceptor end and the donor end, and close gomphosis of the acceptor end and the donor end can be achieved through the chimeric mechanism. The vascular anastomosis device is suitable for vascular anastomosis in the operative processes of organ transplantation such as liver transplantation and heart transplantation. In the operative processes of the organ transplantation, fast, accurate and reliable vascular anastomosis can be achieved, operative process is greatly simplified, the operative difficulty and labor strength of operators are lowered, no organ period and intraoperative blood vessel blocking time are shortened, the operative success rate is improved, and the postoperative complication is lowered.

Description

technical field [0001] The invention relates to a blood vessel anastomosis device, in particular to a blood vessel anastomosis device used in organ transplant operations such as liver transplantation and heart transplantation. Background technique [0002] Organ transplantation is the complex procedure of transplanting a person's healthy organs into a patient's body to replace the patient's non-functional organs due to disease. With the continuous improvement of organ transplantation techniques and perioperative 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 for the treatment of various end-stage organ diseases. [0003] In liver transplantation, the most difficult and technically demanding part of new liver implantation after resection of the diseased liver is the anastomotic reconstruction of the superior hepatic superior vena cava and the ...

AI Technical Summary

Problems solved by technology

Because the acceptor end of the superior and inferior hepatic vena cava is difficult to lengthen and easy to retract, and the caliber varies from 1 to 3 cm, the existing instrument anastomosis cannot be implemented

At present, the common method in the world is still manual continuous valgus suturing. Due to the narrow space, deep position, difficult operation, time-consuming and labor-intensive operation, it takes an average of 35 to 45 minutes, which makes the anhepatic period long during the operation and affects important organs such as the heart, lungs and kidneys. The organ is greatly affected, and the quality control is affected by the technique of the surgeon. Complications such as intraoperative and postoperative bleeding and postoperative anastomotic stenosis are prone to occur, which is the most critical part of the difficulty of liver transplantation.
