Abstract

The invention discloses a double-artery fixing device for arteriovenous internal fistula surgeries. The double-artery fixing device comprises a bending connecting rod, a first fixing clip and a secondfixing clip, wherein the first fixing clip and the second fixing clip are arranged on the bending connecting rod; a chock block is fixedly mounted at one end of the bending connecting rod, threads are formed in the other end of the bending connecting rod, and a nut is fixedly mounted on the threads; a trepanning is formed in the first fixing clip, and a chamfering is formed at the end of the trepanning; a compression spring is fixedly mounted at one end in the first fixing clip, a clamping block is fixedly mounted at the other end of the first fixing clip, the clamping block consists of an upper fixture block and a lower fixture block, and concave-convex blocks are arranged on the upper fixture block and the lower fixture block; a tooth is arranged on one side of the clamping block, and is arranged at the top end on the inner side of the first fixing clip; and a groove is formed in the bottom end corresponding to the tooth, on the inner side of the first fixing clip. The double-arteryfixing device has the beneficial effects that the double-artery fixing device has the advantages of being simple in structure, capable of being folded into different shapes, capable of not damaging blood vessels and the like.

Description

technical field [0001] The invention relates to the field of medical tools, in particular to a double-artery fixation device for arteriovenous fistula operation. Background technique [0002] Venous fistula is a small operation of vascular anastomosis. The artery near the wrist of the forearm and the adjacent vein are sutured together, so that arterial blood flows in the anastomotic vein, forming an arteriovenous fistula. The blood vessels of arteriovenous fistula can provide sufficient blood for hemodialysis treatment and guarantee the adequacy of dialysis treatment. The Chinese patent with the patent publication number CN204520831U discloses a double-artery fixation device for arteriovenous fistula surgery, which includes a fixed connecting rod, a fixed clip I, a fixed clip II, a scale line, threads, and a nut; it is characterized in that: Fixed clip I and fixed clip II are respectively installed on the fixed connecting rod, and scale marks are arranged on the surface; th...
