The shorter the operative time, the more conducive to the postoperative recovery of liver, kidney, heart and lung transplantation, maintain the systemic circulation as soon as possible, reduce the incidence of complications in patients, and facilitate the rapid resurrection of the graft.
现目前在进行血管吻合时，可通过吻合环进行两血管断端之间的吻合，吻合时，将每根血管断端穿过对应的吻合环，再将血管断端的内膜外翻并使血管壁穿挂在吻合环的针体上固定，最后再将两个吻合环扣合即可完成血管的吻合。相比于用针线缝合，吻合环吻合血管能够使两血管间的连接更紧密，吻合效果更好。At present, when performing vascular anastomosis, the anastomosis between the two blood vessel ends can be performed through an anastomosis ring. During anastomosis, each blood vessel broken end is passed through the corresponding anastomotic ring, and then the intima of the blood vessel broken end is everted and made The blood vessel wall is fixed on the needle body of the anastomotic ring, and finally the two anastomotic rings are buckled to complete the blood vessel anastomosis. Compared with suture with needle and thread, the anastomotic ring anastomotic blood vessel can make the connection between the two blood vessels tighter and the anastomosis effect is better.
但是，现目前使用吻合环吻合血管时，仍需医生手动将血管断端的血管壁固定在吻合环的各个针体上，需重复操作多次，操作难度大且耗时较长，并且医生难以把控每次固定时血管壁的牵拉外翻程度，容易导致各个固定位置的血管壁的延展程度不一致，进而导致血管吻合效果不佳。However, when an anastomotic ring is currently used for anastomotic blood vessels, the doctor still needs to manually fix the blood vessel wall at the broken end of the blood vessel on each needle body of the anastomotic ring, and the operation needs to be repeated many times. The operation is difficult and time-consuming, and the doctor is difficult to Controlling the degree of traction and eversion of the blood vessel wall during each fixation may easily lead to inconsistent extension of the blood vessel wall at each fixation position, resulting in poor vascular anastomosis results.
