Bridge vessels-proximal anastomosis supporting device for coronary artery bypass grafting and manufacturing method of bridge vessels-proximal anastomosis supporting device

Abstract

A bridge vessels-proximal anastomosis supporting device for coronary artery bypass grafting and a manufacturing method thereof. The bridge vessels-proximal anastomosis supporting device for the coronary artery bypass grafting comprises an arc-shaped body (1). An elliptical bottom edge (2) is arranged at the lower part of the arc-shaped body (1), a circular port (3) is arranged at the right side of the arc-shaped body (1), a notch is formed between the rightmost end of the bottom edge (2) and the lowermost end of the port, the diameter R of the circular port (3) is 4 mm, 5 mm, 6 mm, 7 mm or 8 mm, the major axis a of the elliptical bottom edge (2) is 13 mm, and the minor axis of the elliptical bottom edge (2) is the same as R. The body (1) is formed by weaving titanium-nickel alloy wires. The bottom edge (2) and the port (3) are provided with a supporting edge (5) made of a heavy metal material, and the supporting edge (5) is fixed with the wires (4) through medical non-absorbable sutures (6) in a wrapping manner. The device can support blood vessels of an anastomosis so as to prevent the blood vessels from generating collapse or deformation due to squeezing during an operation, thereby delaying occlusion of the anastomosis after the operation, and helping complete postoperative coronary angiography easily, accurately and quickly during re-examination.

Description

technical field [0001] The invention relates to the technical field of surgical medical supplies, in particular to a proximal anastomotic port support device for coronary artery bypass grafting and a preparation method thereof. Background technique [0002] Coronary artery bypass grafting is a common procedure to treat coronary artery disease. This procedure uses veins or arteries removed from the chest, leg, or arm, anastomosed proximally to the ascending aorta, and distally across narrowed or blocked coronary arteries to improve blood supply to the heart and reduce the chance of myocardial infarction , thereby improving the quality of life of patients and prolonging life expectancy. Since the anastomotic stoma at the proximal end of the coronary artery bypass grafting graft is a bevel and is sutured directly on the ascending aorta, the anastomotic stoma will collapse after conventional bypass grafting and the blood clot formed by postoperative oozing and coagulation will ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a coronary artery bypass graft graft proximal anastomotic support device, which has the ability to avoid the anastomotic vessel collapse or The characteristics of being squeezed and deformed, thereby reducing the risk of surgery
