Abstract:
A laparoscopic scissors, comprising a pair of blades connected at a pivot, each of the blades having a length, a tip portion, a body portion, an outer surface, an inner surface and a cutting edge is provided. The tip portion may have a first body thickness and the body portion may have a second body thickness different from the first body thickness. During the cutting operation, the blades progressively move over each other to provide a point contact along the cutting edges. In another aspect of the invention, a process of manufacturing the pair of scissors of the invention is disclosed, comprising the steps of forming the blades into a desired shape with wire EDM processes from a pre-hardened block of material, and sharpening the cutting edges of the blades.
