Patent ID: 7686826

Claim:
A surgical instrument comprising: an elongated instrument shaft having proximal and distal ends; a working member coupled from the distal end of the instrument shaft; a control handle disposed at the proximal end of the instrument shaft; an actuator cable coupled between the control handle and working member for controlling the working member; a distal motion means at the distal end of said instrument shaft; a proximal motion means at the proximal end of said instrument shaft; actuation means extending between said distal and proximal means whereby any deflection of said control handle with respect to said elongated instrument shaft causes a corresponding motion of said distal motion means for control of said working member; and means for manually rotating the instrument shaft and working member relative to said control handle; wherein said distal motion means comprises a distal bendable member and said proximal motion means comprises a proximal bendable member that is moveable in any direction; and wherein said proximal bendable member is mounted with and for rotation with said means for manually rotating; said elongated instrument shaft including an outer shaft tube and an inner shaft tube that is coaxially disposed in said outer shaft tube; said outer shaft tube intercoupling said proximal bendable member with said distal bendable member; said inner shaft tube intercoupling said proximal bendable member with said distal bendable member; said outer shaft tube being the outermost shaft tube; said inner shaft tube for accommodating the actuator cable for the working member; both said inner and outer shaft tubes, upon rotation of the means for manually rotating, concurrently rotating with said means for manually rotating.
