Technical Field

The utility model relates to a cardiovascular surgery surgical instruments technical field especially relates to a cardiovascular suture needle wears gasket and uses fixed pincers.

Background

Cardiovascular surgery generally needs to use suture to close heart cavity, to anastomose aorta or suture surface muscle blood vessel of heart for hemostasis, the suture is generally non-absorbable single-strand polypropylene suture, the thread body is smooth and slender, when operating doctors use the suture to close heart cavity or to stop bleeding, the knotting force is small and blood leakage or bleeding can not be stopped, the knotting force is large, the suture has cutting force due to heart beating, and the myocardium is torn to bleed. To prevent this, before using the suture to suture the cardiac muscle or the vascular tissue, the surgeon will first thread the suture needle with the suture into the first suture spacer, then thread the suture needle through the cardiac muscle or the vascular tissue, and thread the suture needle out of the cardiac muscle or the vascular tissue, and then thread the suture needle into the second suture spacer, so that the needle-in end and the needle-out end of the suture have one suture spacer to clamp the cardiac muscle or the vascular tissue, and the cutting force of the needle-in end and the needle-out end of the suture to the cardiac muscle or the vascular tissue is shared on the suture spacer.

At present, a special instrument for enabling a suture needle to penetrate through a suture gasket is lacked, generally, when a medical worker holds a small curved forceps with a left hand to clamp the middle part of the left half part of the gasket, the right half part of the gasket extends out of the small curved forceps in a cantilever shape, when the medical worker enables the suture needle to penetrate through the right half part of the gasket with the right hand, due to the fact that the cantilever part of the gasket is in a free state and lacks of constraint of fixing force, pressure of a needle point enables the gasket with the cantilever extending part to be bent, and therefore the needle point cannot penetrate through the gasket in a direction perpendicular to the gasket.
