本发明提供了一种体内可降解的针环式血管吻合装置,包括吻合环、金属细针、配合孔以及分断缺口，所述吻合环设置有两个，所述金属细针在两个吻合环相对的侧面分别设置有一个或多个，所述配合孔在两个吻合环相对的侧面分别设置有一个或多个，且其一所述吻合环上的任一金属细针均与另一吻合环上的配合孔对应插入配合；所述分断缺口在任一吻合环上均设置有一个或多个。通过在吻合环上设置多个分断缺口，吻合环降解过程中，从分断缺口处断开，使吻合环分解为多段，一方面有助于减少吻合装置降解时对血管的损伤，另一方面有助于减少吻合环长期影响血管正常收缩与舒张的生理功能。

The invention provides a biodegradable needle ring vascular anastomosis device in the body, which comprises an anastomosis ring, a metal fine needle, a matching hole and a breaking notch. The anastomosis ring is provided with two, the metal fine needle is respectively provided with one or more on the opposite side of the two anastomosis rings, and the matching hole is respectively provided with one or more on the opposite side of the two anastomosis rings. And any metal needle on the anastomosis ring is inserted into the matching hole on the other anastomosis ring; One or more of the breaking notches are arranged on either anastomosis ring. By setting multiple break notches on the anastomosis ring, the anastomosis ring can be disconnected from the break gap during the degradation process of the anastomosis ring, so that the anastomosis ring can decompose into multiple segments. On the one hand, it is helpful to reduce the damage to blood vessels caused by the degradation of the anastomosis device, and on the other hand, it is helpful to reduce the physiological function of the anastomosis ring that affects the normal contraction and diastole of blood vessels in the long term.
