CURVED LAPAROSCOPIC SCISSOR HAVING TWO ARCS OF CURVATURE

摘要

A laparoscopic surgical scissors, which has a handle body assembly having an actuation member moveable toward and away from the assembly. An elongated shaft having a proximal and distal end that define a longitudinal axis is connected to the assembly at its proximal end. A pair of cutting blades have a first and second blade member co- operably connected about a common pivot member located adjacent to the distal end of the shaft and defining a common pivot axis perpendicular to the shaft. The first and second blade member have first and second cutting edges, respectively, the second cutting edge facing the first cutting edge, and a single point of blade contact translating proximally and distally as they open and close in response to actuation member movement. Each of the blade members defines a curvature along the shaft longitudinal axis, each curvature having a proximal and distal end. A proximal and distal arc of curvature define the curvature of each of the blade members.
