Problems solved by technology

[0002] At present, when performing end-to-end anastomosis of arterial vessels with small and medium diameters, it is necessary to use vascular clips to block the blood flow of the arteries at the ends of the vessels on both sides, and then manually fix the position and distance of the longitudinal axes of the vessels on both sides by the surgeon. The anastomosis can only be performed after the broken ends are well aligned. During the above-mentioned surgical operations, because the rear end of the existing arterial vascular clip lacks effective fixation, the surgeon usually uses sterile gauze to hold it, but this not only requires repeated Adjusting the position of the arterial clip, more importantly, the fixation effect is poor, and it is impossible to achieve simultaneous fixation of the arterial clips on both sides of the arterial stump. The vertical axis position and angular distance adjustment greatly reduces the stability and flexibility of the operation, prolongs the arterial anastomosis time and affects the surgical effect. In view of this, it is necessary to design an auxiliary fixation device for arterial anastomosis to solve the problem. above question

Abstract

The invention discloses an auxiliary fixing device for artery blood vessel anastomosis. The auxiliary fixing device comprises a fixing plate, sliding grooves, catch grooves, avoiding holes, fixing seats, avoiding grooves, fixing shafts, limiting handles, T-shaped sliding blocks, springs, a multi-angle limiting plates and clamps. Firstly, by designing two fixing structures for clamping artery clamps, a surgeon can conveniently clamp the artery clamps on both sides of the artery stump, which realizes the fixation of the artery clamps on both sides of the artery stump, so that the problem that the artery stump moves freely during the anastomosis process is effectively prevented; secondly, with the cooperation of a horizontal sliding-type size adjusting device, the penetration distance of the artery clamps can be conveniently controlled as needed, so that the convenience of clinical operation is improved; and in addition, under the action of a multi-angle regulation and control device, the angle of each artery clamp can be changed, and finally, the convenience and stability of the artery anastomosis process are greatly improved, and popularization and application of the surgery department are facilitated.
