The present invention relates to a stabilizing device for cardiac surgery used in coronary surgery of the heart, and more particularly, it is possible to prevent the epidermis of the heart sucked up to block the nozzle for inhaling air, the anastomosis device is the outer surface of the heart The present invention relates to a stabilization device for cardiac surgery, which can prevent deviation from, easily change the close contact position of the stabilization device, and prevent the separation from the procedure table during the procedure.

In general, the arteries of the heart send blood to the heart wall and support the heart itself, and there are two arteries to the left and right, which are called coronary arteries.

If at least one of the arteries that send blood to the heart wall and support the heart itself and the arterial vessels on the left and right sides accumulate and thicken fat components such as cholesterol, the blood vessels become narrowed or blocked, resulting in lesions in the arteries and You will not be able to get oxygenated blood.

In addition, angina can occur due to a lack of blood supply to the heart, and clogging of the coronary arteries can result in myocardial infarction or heart attack. On the contrary, in order to treat and treat heart disease, a vessel region is implanted into an artificial vessel by using a coronary artery replacement graft.

As a tool for the procedure, the handle is mounted to one side of the main holder and the main holder, which is conventionally fixed and mounted on the treatment table, and the soluble arm which can be rotated in all directions from the lower side of one side of the handle is mounted, and at the bottom of the soluble arm A head having a suction groove is mounted to suck and lift the outer surface, and a suction pipe having a suction nozzle for sucking air in the head is provided inside the head.

On the other hand, myocardial infarction occurs to treat the obstructive vascular method is mainly used by surgery. A commonly used method for surgery is an end-to-end anastomosis method in which the vessels in question are cut out and then the cut vessels are anastomated.
