The utility model discloses an using value embodies in following several aspects:
transplantation is used clinically to rejuvenate thousands of end-stage patients. The key method for the success of organ transplantation is to connect blood vessels and restore normal blood supply. Meanwhile, the isolated ischemic organ dies in a short time (less minutes, more than 1 hour) at normal temperature, and cannot be used for transplantation. The preservation of organ viability is time-limited. Therefore, the organ transplantation operation must compete for seconds in time.
However, the key link of the transplantation operation, namely the blood vessel anastomosis still uses the original suture technology, inevitably leads to the overlong operation time, uncertain suture quality and difficult alignment and anastomosis butt joint of the blood vessel intima, which is the first reason for the failure of a large number of transplanted organs.
The original blood vessel anastomosis suturing technology invented by Karrel in 1903 is difficult to ensure that intima at the two broken ends of blood vessels are aligned correctly, blood leakage is avoided after suturing, postoperative blood vessels are not narrow, smooth blood flow is ensured, blood supply of the sutured blood vessels is ensured, and small blood vessels are not constricted annularly. Too many suture knots are used, and the operation time is difficult to be ensured to be shorter than the activity time of organs. When suturing and ligating are too tight, blood circulation is difficult to ensure. For the reasons, the uncertainty of the manual blood vessel suturing technology is randomly amplified, the operation time is easily longer than the organ activity time, and the organ is not alive even if the blood vessel is sutured. Or, poor quality of vessel suturing, vessel contracture, and unsmooth blood supply, which leads to difficult organ survival after operation, and results in a large number of failure cases of organ transplantation.
People have a big life like a day. In order to save the life of people, the people must race at the same time, and the quality of the anastomosis of blood vessels must be ensured. The technique of suturing blood vessels in transplanted organs is a bottleneck which consumes a lot of operation time and ensures uncertain quality of the blood vessel suture. Therefore, the connecting pipe for anastomosis of the blood vessel and the intestinal canal realizes the quick guide, fixation, support and closed anastomosis mode of the blood vessel and the intestinal canal in a pioneering way, and improves the success rate of the transplanted organ operation. The convenient guide connection mode greatly shortens the operation time. Particularly, the stable blood vessel and intestinal canal support guiding fitting anastomosis mode ensures accurate and comprehensive infiltration and butt joint of blood vessel intima, is convenient for quickly establishing blood supply of the blood vessel and greatly improves the success rate of anastomosis of the blood vessel and the intestinal canal.
Compared with the original suture technology, the connection mode of the blood vessel and intestinal tube anastomosis connecting tube cannot be in the same day. In terms of efficiency, it is different from Gui-rabbit. In the prior art of blood vessel suture, at least 12 knots are needed to be sewed through the connection suture of one blood vessel, and more knots are needed to be sewed through the multiple knots, however, the time for connecting the blood vessel of the utility model even the time for sewing one knot through the traditional suture is not needed, and the efficiency is dozens of times of that of the traditional suture technology. In terms of the quality of anastomosis of the blood vessel and the intestinal tube, the connection, fixation, support and attachment mode of the blood vessel and intestinal tube anastomosis connecting tube is safe, determined, stable and efficient. The anastomotic suture technique of original blood vessel is difficult to guarantee that the broken ends blood vessel intima of both sides aligns correctly, however the utility model discloses an identical mode has successfully solved this problem, the identical accurate reliable and stable of blood vessel intima, and the survival rate is high.
The utility model discloses a transplantation medical history is last to stride century's innovation, has thoroughly rewritten traditional blood vessel anastomosis method, provides brand-new, stable, efficient blood vessel, intestines tube connected mode, and is very big to improving transplant organ survival rate meaning, and is very big to the life health meaning that continues the people, and is very big to organ donor's spirit comfort meaning.
