Surgical instrument
DCFirst Claim
1. A manually operated medical instrument having an instrument shaft that couples with an operating handle at a proximal end thereof and a tool at a distal end thereof, further comprising a proximal bendable member at the proximal end of the instrument shaft that is bendable into a curved configuration, a distal bendable member at the distal end of the instrument shaft that is bendable into a curved configuration, and one or more actuating elements intercoupling the proximal and distal bendable members responsive to a manually initiated bending at the proximal bendable member to cause a corresponding bending into a curved configuration of the distal bendable member so as to control, via the handle, the positioning of the tool.

Abstract
The surgical instrument includes a distal tool, a rigid or flexible elongated shaft that supports the distal tool, and a proximal handle or control member, where the tool and the handle are coupled to the respective distal and proximal ends of the elongated shaft via distal and proximal bendable motion members. Actuation means extends between said distal and proximal members whereby any deflection of said control handle with respect to said elongated instrument shaft causes a corresponding bending of said distal motion member for control of said working member. A manually rotatable member is arranged adjacent to the control handle for manually rotating the instrument shaft and working member relative to the control handle.

12. A surgical instrument comprising:
-
an elongated instrument shaft having proximal and distal ends; a working member disposed from the distal end of the instrument shaft; and a control handle disposed from the proximal end of the instrument shaft; a distal bendable member capable of bending into a curved configuration; said working member being coupled to the distal end of said elongated instrument shaft via said distal bendable member; a proximal bendable member capable of bending into a curved configuration; said control handle coupled to the proximal end of said elongated instrument shaft via a proximal bendable member; a manually rotatable member arranged adjacent the control handle and between the control handle and proximal bendable member; said rotatable member adapted to be manually rotated to, in turn, rotate the instrument shaft, distal bendable member and working member relative to said control handle; and an actuation element extending between said distal and proximal bendable members whereby any deflection of said control handle with respect to said elongated instrument shaft causes a corresponding bending of said distal motion member for control of said working member. - View Dependent Claims (13, 14, 15)
