Abstract

Abstract A cable action instrument for surgery and other uses comprises a control end, a reaction end, and an angle adjustment section connecting the control end and the reaction end. A flexible control cable extends between the control end and the reaction end and allows a force to be transmitted from the control end to the reaction end so that a desired function may be performed at an instrument tip. The instrument may be bent into an unlimited number of configurations and is easily disassembled and reassembled.
