Abstract

Disclosed is an artery stapler, comprising a stapler shell (12), and a stapling bracket (1), a pressing arm (3), a bracket control rod (6) and a pressing arm control rod (4) arranged on the stapler shell (12), wherein a sealing disc capable of being opened or closed is arranged at the front end of the stapling bracket (1); the pressing arm (3) is arranged above the stapling bracket (1), a pressing disc (31) is arranged at the front end of the pressing arm (3), and the pressing disc (31) is arranged opposite to the sealing disc; the bracket control rod (6) is connected to the stapling bracket (1) and used for controlling the sealing disc to be opened or closed; and the pressing arm control rod (4) is connected to the pressing arm (3) and used for controlling the pressing arm (3) to press down or lift up. The artery stapler can solve the problem that the existing stapler causes large vascular injuries to the aorta of the heart and is inconvenient for operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an arterial stapler. Background technique [0002] Coronary artery bypass grafting, commonly known as coronary artery bypass grafting, abbreviated as CABG, is a surgery used to repair or replace blocked coronary arteries to improve blood supply to the heart muscle. The surgical approach is to use grafted blood vessels (usually the great saphenous vein and internal mammary artery) to create a vascular access in the distal end of the aorta and obstructed coronary artery. Let the blood from the heart beat from the aorta pass through the vascular bridge, and flow to the distal end of the coronary artery caused by stenosis or obstruction to reach the ischemic myocardium, thereby improving the ischemic and hypoxic state of the myocardium. Generally speaking, when the stenosis of the coronary artery lumen is less than 50%, the blood flow is not greatly affected, and the use...
