Blood vessel anastomat

Abstract

The invention relates to a blood vessel anastomat, which comprises a left needle pushing device, a right needle pushing device and a centre unit in butt joint with two sections of blood vessels; the centre unit comprises a sliding part in the middle and butt joint parts at the two ends and in butt joint with a blood vessel; a plurality of groups of needle threading parts are circumferentially arranged on the centre unit at intervals; each group of needle threading parts comprises a left needle threading part and a right needle threading part which are arranged left and right; the left needle threading part and the right needle threading part are both provided with suture needles; furthermore, the two corresponding suture needles in each group are connected through the same suture line; the left needle pushing device and the right needle pushing device are arranged on the sliding part in a sliding and sleeving manner; and the left needle pushing device and the right needle pushing device are respectively provided with a needle pushing part used for pushing the suture needle out of the butt joint part. Compared with a traditional blood vessel anastomat, the butt joint uniformity of the two ends is guaranteed; corresponding operation steps are reduced; the pain of a patient is relieved; the left needle pushing device and the right needle pushing device can enable the suture needle to penetrate through blood vessels at the two ends at the same time under the action of external force; threading operation is achieved; operation is easy; and butt joint efficiency and precision are high.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a blood vessel stapler. Background technique [0002] Vascular repair and reconstruction surgery mainly involves various anastomosis and repair of blood vessels. It mainly includes two processes as a whole, one is the butt joint of broken blood vessels, and the other is suture. The butt joint of broken blood vessels is a crucial step. The effect of butt joint Good or bad will directly affect the effect of subsequent butt joint healing. Publication No. CN2472666Y patent document discloses a blood vessel stapler, which uses a mandrel and a pusher plate to respectively thread the broken blood vessels at both ends with sutures, and finally sew them together, which solves the inaccuracy of traditional manual docking to a certain extent. However, the vascular stapler requires two operations, that is, docking one end first, and then docking the other end, which is relatively cumberso...
