Abstract

The invention relates to a blood vessel end-to-end anastomosis apparatus, aiming to effectively solve problems of alignment and difficulty in vascular suture. The technical scheme includes that the blood vessel end-to-end anastomosis apparatus comprises an internal support section and an external support section, the internal support section includes on L-shaped bar, one end of the L-shaped bar ishinged with multiple first connecting rods in uniform circumferential distribution, the outer end of each first connecting rod is hinged with one second connecting rod, the outer end of each second connecting rod is hinged with one third connecting rod, outer ends of the multiple third connecting rods are hinged on a same disk, the three connected connecting rods form a hinged chain, the other end of the L-shaped bar is sleeved with one sleeve, a plunger is installed in the sleeve, friction damping is formed between the plunger and the sleeve, the L-shaped bar is of a hollow structure, one pull rope penetrates the inner cavity of the L-shaped bar, one end of the pull rope is fixed onto the disk while the other end is fixed onto the plunger, and the external support section includes two arc compression plates. By the arrangement, the operation difficulty in vascular suture is effectively reduced, and the probability of thrombosis is reduced.

Description

technical field [0001] The invention relates to the field of blood vessel anastomosis, in particular to a blood vessel end-to-end anastomosis device. Background technique [0002] End-to-end anastomosis of blood vessels is a common method for reconstructing broken vascular access. During end-to-end anastomosis of blood vessels, the broken ends should be aligned accurately and flatly, and no constriction and twisting and dislocation will occur after blood vessel suturing. Otherwise, the probability of thrombosis will be greatly increased; current vascular anastomosis The method of suturing with sutures after hemostasis with blood vessel clips is used. During alignment and suture, the blood vessels are in a flat state, which makes the alignment difficult, and the blood vessels are easy to reverse and misplace, resulting in narrowing or twisting of the blood vessels after suture, and the needle goes in and out during suture. The needle needs to be very careful to prevent it fro...
