Description

Technical Field

[0001] The utility model belongs to the technical field of organ transplantation, and particularly relates to an anastomotic sleeve. Background Art

[0002] Organ transplantation is a medical procedure that involves transplanting a healthy organ from one individual into another individual whose life is in danger or whose quality of life has been severely reduced due to loss of function or failure of the original organ, in order to restore or improve the recipient's physiological functions. Transplanted organs usually come from living donors or cadaveric donors who have died of brain death or cardiac death. In organ transplantation surgery, a stapler is a special surgical instrument used to quickly and accurately connect the blood vessels and / or digestive tract between the transplanted organ and the recipient tissue, and a corresponding sleeve is often added to the outside of the stapler to protect the stapler and prevent damage to the stapler, which would result in high repair and replacement costs. However, most common anastomotic sleeves are one-piece structures, which need to be customized according to the size of the stapler. After the customization of the anastomotic sleeve is completed, it can only be used for a specific model of stapler, which limits the use scenarios of the anastomotic sleeve and cannot be replaced according to actual conditions.

[0003] Secondly, when the integrated anastomotic sleeve is partially damaged, in order to ensure the protection of the stapler, the entire set of anastomotic sleeve needs to be replaced, which will increase the corresponding cost and cause a certain amount of waste.

[0004] In summary, there are certain problems in the use of the integrated anastomotic sleeve, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
