Method of manufacturing a gripping surface for an end effector and surgical instrument comprising a gripping end effector

Abstract

A manufacturing method by wire electro-erosion includes providing a wire electro-erosion machine having a cutting wire; mounting at least one workpiece to the wire electro-erosion machine; and making a surface micro-topography by wire electro-erosion. The method includes performing a first through cut on the workpiece according to a cutting path having peaks and valleys, thus exposing an exposed portion on the workpiece comprising reliefs and recesses corresponding to the peaks and valleys of the first cutting path. A surgical instrument includes at least one gripping surface having a surface micro-topography.
