Abstract
Abstract A surgical needle apparatus having an elongated metal body tapered at one end and having a suture material holding means at the opposite end. The opposite end is split with the end of the split formed into gripping jaws for gripping suture material, and the split portions have raised areas between the end of the split so that compressing the non-raised area together will force the raised area in the split to force the gripping jaws to open for inserting and removing suture material.

Claim 1
Independent Claim
151 words
A surgical needle comprising an elongated arcuate stainless steel body having a tapered end portion and a flat blunt end portion; said blunt end having an elongated split extending axially from the flat tip thereof, each side of said split being shaped with matching pairs of concave surfaces joined by a convex surface therebetween and gripping jaws adjacent the tip of the blunt end and adjacent to and intersecting one pair of concave surfaces for holding suture material, said elongated split being perpendicular to the concave and convex curvature of said needle body, whereby compressing one pair of concave surfaces towards each other will compress convex surfaces together along their curvature and open said gripping jaws to engage or release suture material, and said gripping jaws having sharpened curved edges arced between edges of each said side of said blunt end split opening for biting and holding stainless steel suture material.
