Abstract

Surgical scissors are provided having two scissor blades mounted for pivotal movement relative to each other about a pivot axis and having one cutting edge each. The scissor blades have, proximal of the pivot axis, one sliding surface area each, the sliding surface areas sliding along each other and the scissor blades contacting each other distally of the pivot axis at a moving point of contact of the cutting edges sliding along each other when the scissors are opened and closed. At least one of the cutting edges is provided with a hard material coating, and at least one of the two sliding surface areas have a first hard material coating-free surface. A method for the manufacture of surgical scissors is also proposed.
