Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of aorta sidewall proximal blood vessel anastomat.
Background technology
Aorta is the arteriosus truncus of body circulation, can be divided into ascending aorta, aortic arch and descending aorta three part.Ascending aorta plays the aortic orifice from left ventricle, to front upper right diagonal, continues in aortic arch; Left and right coronary artery is sent at aortal root.Aortic arch connects ascending aorta, does arciformly to bend towards left back in presternal rear, divides a word with a hyphen at the end of a line in descending aorta; On aortic arch, send 3 large branches, right-to-left is followed successively by brachiocephalic trunk (innominate artery), left common carotid artery and left subclavian artery; Brachiocephalic trunk, to upper right side diagonal, is divided into right common carotid artery and right subclavian artery to right sternoclavicular joint rear.Descending aorta is the longest one section of aorta, above connects the aortic hiatus that aortic arch is dropped through diaphragm before body of thoracic vertebre and enters abdominal cavity; Continuing and to decline before lumbar vertebra, is left and right common iliac artery to the 4th lumbar vertebral body punishment; Descending aorta for boundary, is divided into above thoracic aorta (aorta thoracica) with the aortic hiatus of diaphragm, and following is ventral aorta (abdominal aorta).
Coronary artery bypass grafting, is commonly called as coronary artery bypass, english abbreviation CABG, is for repairing or replace the coronary artery that blocks to improve the operation of cardiac myocytes blood confession.Operation method is set up a vascular access with the blood vessel (normal for great saphenous vein and IMA) transplanted at aorta and the coronary artery far-end that blocks.The blood allowing heart put out, from the vessel bridges of aorta through institute's frame, flows to the cardiac muscle arriving ischemia because causing coronary artery far-end that is narrow or that block, thus improves ischemia, the anaerobic condition of cardiac muscle.In general, coronary artery luminal stenosis lower than 50% time, little on the impact of blood flow, use Drug therapy both can have satisfied curative effect.When narrow reach 75% time will obviously affect the unobstructed of blood flow and produce angina pectoris symptom.Now just need to carry out intervention support operation or the treatment of surgery bypass surgery.To having coronary artery multivessel disease, diffuse lesion, and merging valve pathological changes, ventricular aneurysm patients with coronary heart disease, bypass operation of coronary artery is quite effective Therapeutic Method.
Along with patient requires and the raising day by day of level operative treatment, the apparatus applied in operation process also constantly progressive, upgrade.By the application of assistive device, better coordinate doctor to complete high-quality operation, be convenient to doctor and use, operate, and not easily in use damage is caused to patient.Increasing research shows, after the coronary bypass surgery miscellaneous of extensive existence, in the recent period and long term complication be due in performing the operation wholly or in part caused by clamp aorta, so reduce the blood vessel anastomat of aorta sidewall pincers use by Devoting Major Efforts To Developing, blood vessel anastomat is a kind of device that can realize blood vessel and effectively coincide fast in heartbeat situation.Compared with clamping with sidewall, more can provide a visual area that is stable, depletion of blood and better hemodynamics to surgeon.But still there is the easily problem such as damage aorta and operation inconvenience when existing blood vessel anastomat uses in art, and the Hemodynamic response of anastomotic position is on the formation affecting neointimal hyperplasia, acute thrombus.
