Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of arterial anastomosis device.
Background technology
CABG, off pump coronary artery bypass is commonly called as, english abbreviation CABG, is for repairing or replacing obstruction
Coronary artery is to improve the operation of cardiac myocytes blood supply.Operation method is that (normal is to be moved in great saphenous vein and breast with the blood vessel of transplanting
Arteries and veins) sustainer and the coronary artery of obstruction distal end establish a vascular access.The blood that heart is put out is allowed to pass through institute from sustainer
The vessel bridges of frame, the cardiac muscle that ischemic is reached because causing narrow or obstruction coronary artery distal end is flowed to, so as to improve cardiac muscle
Ischemic, anaerobic condition.In general, when coronary artery luminal stenosis is less than 50%, the influence to blood flow is little, is controlled using medicine
The effect for the treatment of can be both satisfied with.When it is narrow reach 75% when will significantly affect the unobstructed of blood flow and produce angina pectoris symptom.This
When just need carry out intervention support operation or surgery bypass surgery treatment.To having coronary artery multivessel disease, diffusivity
For lesion, and the patients with coronary heart disease of merging valve lesion, aneurysm, bypass operation of coronary artery is fairly effective treatment side
Method.
As patient requires operative treatment the increasingly raising with level, the apparatus applied in surgical procedure is also continuous
Progressive, renewal.By the application of assistive device, preferably coordinate doctor to complete high-quality operation, be easy to doctor to use, operation,
And it is not easy in use patient to be caused to damage.More and more research shows, the miscellaneous coronary artery being widely present
After bypass surgery, in the recent period and long term complication is due in operation caused by complete or partial clamp sustainer, is then reduced actively
Arteries and veins blocks the blood vessel anastomat that pincers use, and by Devoting Major Efforts To Developing, blood vessel anastomat is that one kind can realize blood in the case of heartbeat
Manage fast and effective identical device.Compared with aortic occlusion clamp, be better able to surgeon provide one it is stable, without blood
Visual area and more preferable haemodynamics.But current vascular anastomosis apparatus still suffers from easily damage actively in surgical procedure
The problems such as arteries and veins and inconvenient operation, it is unfavorable for patient's post-operative recovery.
