Abstract

The invention relates to a blood vessel anastomat. An outer-sheath blood vessel sleeve shaft and an inner-sheath blood vessel sleeve shaft are fixed to the two sides of a connector respectively, bloodvessel limiting structures are arranged at the inner sides of the outer-sheath blood vessel sleeve shaft and the inner-sheath blood vessel sleeve shaft respectively, outer-sheath blood vessel pressing heads are uniformly distributed in the circumferential direction of the outer-sheath blood vessel sleeve shaft and can be matched with the shaft surface of the outer-sheath blood vessel sleeve shaftto tightly press the outer-sheath blood vessel, and inner-sheath blood vessel pressing heads are uniformly distributed in the circumferential direction of the inner-sheath blood vessel sleeve shaft and can be matched with the shaft surface of the inner-sheath blood vessel sleeve shaft to tightly press the inner-sheath blood vessel; opening blades are uniformly distributed in the circumferential direction of the outer-sheath blood vessel sleeve shaft and can be matched with the shaft surface of the outer-sheath blood vessel sleeve shaft to incise the outer-sheath blood vessel, the portions, corresponding to the opening blades, of the outer-sheath blood vessel sleeve shaft are provided with outer-sheath blood vessel threading grooves, the inner-sheath blood vessel sleeve shaft is provided with inner-sheath blood vessel sleeving threading grooves in the circumferential direction, and the circumferential positions of the inner-sheath blood vessel sleeving threading grooves correspond to the outer-sheath blood vessel threading grooves. By means of the blood vessel anastomat, the blood vessel anastomosis precision can be guaranteed, the surgical operation difficulty is lowered, and thesurgical efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of blood vessel anastomosis connection, in particular to a blood vessel stapler. Background technique [0002] The existing Ren's vascular anastomosis operation (Ren anastomosis) is a completely manual operation process, and the surgical steps generally include: preliminary preparations such as blood vessel exposure - pruning of the vessel section - 180° opening of the sleeve end of the vessel - the opening side of the sleeve end and sleeve insertion Two-needle suture at the outer end—two-needle self-sew at the coat end—post-operation. [0003] In order to ensure a better anastomotic effect, the existing vascular anastomosis requires high precision in micromanipulation, which also leads to a long operation time, and requires a long period of training for the surgeon before performing the operation. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide...
