Surgical instrument
DCFirst Claim
1. A surgical instrument comprising:
- an elongated instrument shaft having proximal and distal ends;
a tool disposed from the distal end of the instrument shaft and supported extending along a distal tool axis;
a control handle disposed from the proximal end of the instrument shaft;
a distal bendable member for coupling the distal end of said elongated instrument shaft to said tool;
a proximal bendable member for coupling the proximal end of said elongated instrument shaft to said handle;
actuation means extending between said distal and proximal bendable members for coupling motion of said proximal motion member to said distal motion member for controlling the positioning of said tool; and
a rotation knob adjacent the control handle and rotatable relative to the control handle for causing a corresponding rotation of the tool about said distal tool axis.

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.

- 13. 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, said distal bendable member having a different transverse cross-sectional dimension than that of said proximal bendable member, 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.

36. 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; 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 manually rotatable member adapted to be manually rotated to, in turn, rotate the proximal bendable member, 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 bending of said proximal bendable member and a corresponding bending of said distal bendable member for control of said working member. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)
