Abstract

The invention discloses a blood vessel anastomat, and relates to the technical field of blood vessel anastomosis appliances. The blood vessel anastomat comprises an anastomosis piece and a clamping piece, wherein the anastomosis piece comprises a left anastomosis ring and a right anastomosis ring which are oppositely arranged, the left anastomosis ring comprises a left ring body and a plurality offirst arc pieces, and the right anastomosis ring comprises a right ring body and a plurality of second arc pieces; the clamping piece comprises a left clamping clamp and a right clamping clamp whichare oppositely arranged, the left clamping clamp comprises a first opening ring and a first clamp handle, and the right clamping clamp comprises a second opening ring and a second clamp handle. The technical scheme is different from a traditional anastomosis structure, each fixing needle is cut off while the broken end of the blood vessel is anastomosed, and a fixing needle unit is clamped out after falling off, so that the subsequent operation step of detaching the fixing needles one by one is avoided, and the operation convenience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of blood vessel anastomotic devices, in particular to a blood vessel stapler with convenient operation. Background technique [0002] Vascular anastomosis is a surgical technique that connects two blood vessels into one. Vascular anastomosis technology began more than one hundred years ago with the application of manual sutures such as Carrel, A, (1908) and Hopfnet, E, (1903) for vascular grafting and replantation of amputated limbs. After more than one hundred years of development, this The technology has been widely used in various surgical procedures. For example, in microsurgery, plastic surgery, hepatobiliary surgery, cardiothoracic surgery, urology, obstetrics and gynecology, etc., vascular anastomosis technology is required. Vascular anastomosis technique is one of the most important steps in the above-mentioned operation, and its success or failure is directly related to whether the transplanted ti...
