Description

A kind of fixed forceps for cardiovascular suture needle threading spacer

technical field

The utility model relates to the technical field of cardiovascular surgical instruments, in particular to a fixed forceps for a cardiovascular suture needle through a gasket.

Background technique

Cardiovascular surgery generally requires the use of sutures to close the heart cavity, anastomose the aorta or suture the muscles and blood vessels on the surface of the heart to stop bleeding. The sutures are generally non-absorbable single-strand polypropylene sutures with smooth and slender sutures. The surgeon uses sutures to close the heart. In cavity or hemostasis, the force of tying the knot is small, which will cause leakage or unstoppable bleeding. The force of tying the knot will cause the suture to have cutting force due to the beating of the heart, which will tear the myocardium and bleed. To prevent this from happening, the surgeon will pass a suture with sutures through the first suture spacer before using sutures to close the heart muscle or blood vessel tissue, and then pass the needle through the heart muscle or blood vessel tissue, After the suture needle is pierced from the myocardium or vascular tissue, the suture needle is inserted into the second suture spacer, so that there is a suture spacer at the needle entry end and the needle exit end of the suture to clamp the myocardium or vascular tissue. The cutting force of the suture into the needle end and the needle out end to the myocardium or vascular tissue is shared on the suture spacer.

At present, there is a lack of special equipment for passing the suture needle through the suture gasket. Generally, the medical staff holds a small curved forceps with their left hand to hold the middle of the left half of the gasket, and the right half of the gasket extends out of the small curved forceps in a cantilever shape. When the medical staff put the suture needle through the right half of the spacer with the right hand, because the cantilever part of the spacer is in a free state and lacks the restraint of the fixing force, the pressure of the needle tip makes the spacer of the cantilever-like projecting part bend, so the needle point cannot Passing through the spacer perpendicular to the spacer, this condition is especially serious when using softer and thinner spacers, such as pericardial spacers, the needle tip penetrates the suture spacer at an angle, which can cause knots The actual thickness of the contact part between the rear suture gasket and the suture is less than the nominal thickness of the suture gasket, which seriously reduces the sharing effect of the suture gasket on the suture cutting force.

Utility model content

The technical problem to be solved by the utility model is: at present, there is a lack of special equipment for passing the sewing needle through the suture gasket.
