Embodiment Construction

[0025] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0026] Examples, see Figure 1 to Figure 4 Shown: the proximal anastomotic support device for coronary artery bypass grafting includes a body 1 . The body 1 is in the shape of an arc tube with a gap 7 , a bottom edge 2 at its lower part, and a port 3 at its right side. The bottom edge 2 is oval and the port 3 is circular. The diameter R of the circle formed by the port 3 is: R=4mm, R=5mm, R=6mm, R=7mm or R=8mm. Having such circular diameters of different sizes can better match the inner diameters of different blood vessels. The major axis a of the ellipse formed by the base 2 is: a=13mm, and the minor axis of the ellipse is the same as R. The notch 7 is located between the rightmost end of the bottom edge 2 and the lowermost end of the port 3, so that the notch 7 can make the supporting device have a certain ...

Abstract

The invention discloses a bridge vessels-proximal anastomosis supporting device for coronary artery bypass grafting and a manufacturing method of the bridge vessels-proximal anastomosis supporting device. The bridge vessels-proximal anastomosis supporting device for the coronary artery bypass grafting comprises an arc-shaped body, the body is formed by weaving titanium-nickel alloy wires, wherein an elliptical bottom edge is arranged at the lower part of the arc-shaped body, a circular port is arranged at the right side of the arc-shaped body, a notch is formed between the rightmost end of the bottom edge and the lowermost end of the port, diameter R of the circular port is 4mm, 5mm, 6mm, 7mm or 8mm, long axis a of the bottom edge is 13mm, and minor axis of the bottom edge is the same as R. The bottom edges and the port are provided with supporting edges made from heavy metal materials, and the supporting edges are fixed with the wires through medical nonabsorbable sutures in a wrapping manner. The bridge vessels-proximal anastomosis supporting device disclosed by the invention can be used for supporting blood vessels of an anastomosis and preventing the blood vessels from generating collapse or deformation due to squeezing during the operation, realizing delaying occlusion of the anastomosis after the operation, and helping complete postoperative coronary angiography easily, accurately and quickly during the reexamination.

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 ...
