Problems solved by technology

However, in the specific operation, it was found that the adventitia of some bridge vessels is thin, especially the adventitia of the great saphenous vein is very thin, it is not easy to clamp, and it is also difficult to control the opening direction of the bridge vessels. It may damage blood vessels, especially the intima of blood vessels, and affect the long-term patency rate of grafted vessels

Abstract

The invention relates to a blood vessel holder which comprises a holder body; the holder body is cylindrical; an elastic clamping piece is fixedly connected to the outer side wall of the holder body;and a clamping opening capable of clamping a blood vessel is formed by the holder body and the elastic clamping piece. The blood vessel holder can well clamp a bridge blood vessel, and is easy to control and small in damage to the blood vessel.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood vessel holder. Background technique [0002] Coronary artery bypass grafting (CABG) anastomoses the great saphenous vein, radial artery, and internal mammary artery to the coronary artery according to the needs of the patient. During the anastomosis process, these self-grafting vessels need to be clamped so that the blood in the aorta can pass through the stenosis of the vessel. The site of the stenosis is perfused directly to the distal end of the stenosis, thereby restoring blood supply to the myocardium. During the operation, tweezers are usually used to hold the adventitia of the vessel to control the opening direction of the graft vessel. After 3 stitches are sutured, the proline suture is tightened to fit and fix the coronary artery incision. However, in the specific operation, it was found that the adventitia of some bridge vessels is thin, especially ...
