Embodiment Construction

[0032] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0033] The forward direction in the present invention refers to along Figure 1-4 Right-to-left direction, front end pointing to yes Figure 1-4 The relative position of the left side, the backward direction and the rear end and the tail end are opposite. "Adaptation" in the present invention means that the quantity is consistent or the shape is matched with each other.

[0034] refer to figure 1 and figure 2 , the coronary artery bypass graft proximal anastomosis device (hereinafter referred to as the anastomosis device) of the present invention includes a first track ring 1, a second track ring 9 and a stent 2, and the stent 2 is located between the first track ring 1 and the second track ring 9 between. The first track ring 1 includes a front end and a tail end, the front end is conical, and the tail end is an inverted truncated cone. Th...

Abstract

An anastomosis device used in the surgical department utilizes a first acting part (1) and a second acting part (9) to be close to each other and further enable two ends of a deformation part (2) to be outwards turned for deformation, the tissue is clamped between the two ends, and further tissue anastomosis is achieved. The far-end anastomosis of a bypass blood vessel in coronary artery bypass transplantation surgery is improved, the anastomosis device is convenient to operate, safe, reliable, even in edge distance and even in stress and is easy to popularize, the patency rate and long-term treating effect of an anastomotic stoma can be improved, operation time can be shortened, and operation success rate can be improved.

Description

technical field [0001] The invention relates to a near-end anastomosis device for coronary artery bypass grafting and a use method thereof, which are used for anastomosis of bridge vessels and ascending aorta. Background technique [0002] In recent years, coronary artery bypass grafting has been widely carried out in my country, and coronary artery bypass grafting has gradually developed towards minimally invasive, small incision, endoscopic and robotic assistance. In conventional coronary artery bypass grafting, partial clamping of the ascending aorta is required to complete the proximal coronary anastomosis, but intubation and clamping of the ascending aorta with atherosclerosis can cause intimal plaques to fall off and cause cerebral palsy. Stroke, and air or microthrombosis in extracorporeal circulation can also cause cerebral infarction. Therefore, neurological complications are one of the most common and serious complications after coronary artery bypass grafting, wh...
