Background technique

The graft vessels used in coronary artery bypass grafting surgery are mainly autologous internal mammary artery and great saphenous vein grafts. In the process of obtaining and preparing the graft vessels, an important step is the treatment of vascular collaterals. For the treatment of vein graft collaterals, the collateral vessels are usually clamped with Mosquito clamps and then ligated with silk threads, or double clamped with titanium clips and then cut off. The treatment of internal mammary artery grafts requires direct treatment of side branches in situ and the operating space is narrow. Basically, double clamping and then disconnection with titanium clips are used in situ. Whether suture ligation or the current titanium clip clamping method is used, there are basically three steps to complete, namely clamping/ligating the proximal segment, clamping/ligating the distal segment, and disconnecting. This method is relatively cumbersome. low efficiency.

In addition, during surgical operations, in order to fully expose the surgical field of view, it is usually necessary to ligate the broken blood vessels in the incision to prevent bleeding. Hemostasis technology has become one of the core of basic surgical operating techniques. Surgery on any part of the human body The procedure almost invariably involves bleeding and hemostasis. The method of hemostasis is based on the same principle as the treatment of coronary artery bypass grafting. Generally, the broken blood vessel is clamped with a hemostatic forceps and then ligated with sutures, or the titanium clip is used to double clamp and then cut off. This method also requires at least The three-step operation is completed, which is more troublesome and reduces the efficiency of the operation. Therefore, there is an urgent need in this technical field for a surgical instrument that can simultaneously clamp both ends of a blood vessel and cut off the blood vessel to simplify the surgeon's operation process of this type of surgery.
