Surgical Instrument

Abstract

A surgical apparatus for use in endoscopic surgery having a user interface operatively coupled to an articulating tool assembly via an elongate tubular member. Movement at the articulating tool directly corresponds to movement at the user interface thereby providing intuitive operation of the surgical apparatus. The apparatus is configured such that the range of motion of the articulating tool assembly emulates the range of motion of the human wrist.

What is claimed is: 
     
         1 . An instrument comprising:
 an elongate tubular member having a distal end and a proximal end;   an user interface coupled to said proximal end;   an articulating tool assembly coupled to said distal end;   at least one cabling member extending through the elongate tubular member, said cabling member operatively connecting said user interface and said articulating tool assembly such that movement made at said articulating tool assembly directly corresponds to and mimics movement of said user interface.
