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. A locking member is supported from the control handle and has locked and unlocked states; in the unlocked state enabling control of the distal work member from the proximal control handle via the bendable members; and in the locked state, holding the bendable members in a pre-selected relative fixed position.

1. A surgical instrument comprising: an instrument shall having proximal and distal ends;a tool disposed from the distal end of the instrument shaft;a control handle coupled from the proximal end of the instrument shaft and having a proximal end where the control handle is grasped and a distal end;a distal motion member for coupling the distal end of said instrument shaft to said tool;a proximal motion member for coupling the proximal end of said instrument shall to said control handle;actuation cabling extending between said distal and proximal motion members for coupling motion of said proximal motion member to said distal motion member for controlling the positioning of said tool;said proximal motion member including at least one partially spherical element;said control handle having formed at the distal end thereof a partially spherical formed socket for receiving the at least one partially spherical element;a locking mechanism for fixing the position of the said proximal motion member at a selected position and having locked and unlocked states;said locking mechanism including a locking lever that is mounted at the control handle and movable relative to the control handle, and a slideable locking piece responsive to the manual operation of the locking lever and terminated at the proximal motion member for selectively locking a bent position of the proximal motion member to, in turn, maintain via said actuation cabling a corresponding bent position of the distal motion member;a tool actuation lever mounted at the control handle for actuating the tool and a tool actuation cable that connects the tool actuation lever to the tool;a rotation knob mounted at the control handle and rotated relative to the control handle for controlling the tool to rotate about a distal tool axis so as to control the orientation of the tool;said rotation knob mounted at the control handle and disposed at a location that is proximally of at least a part of the proximal motion member;a torque transmission member coupled with and extending distally from the rotation knob for controlling the orientation of the tool;said locking lever mounted at the control handle at a position that is between the proximal motion member and at least part of the tool actuation lever;said rotation knob further mounted at the control handle at a location that is adjacent to the locking lever;whereby, when the locking lever is moved to the locked state, the locking piece is slid linearly causing the partially spherical element of the proximal motion member to lockingly engage the partially spherical formed socket to thus hold the proximal motion member in the selected fixed position. 2. The surgical instrument of claim 1 wherein said locking lever is mounted at the control handle at a location that is spaced proximally from the proximal motion member. 3. The surgical instrument of claim 1 wherein the rotation knob is located between the tool actuation lever and at least a part of the proximal motion member. 4. The surgical instrument of claim 1 wherein the tool actuation lever includes a manual engagement section and a pivot for the tool actuation lever from the control handle. 5. The surgical instrument of claim 4 wherein the rotation knob and locking lever are both disposed closer to the distal end of the control handle than at least part of the manual engagement section of the tool actuation lever. 6. The surgical instrument of claim 4 wherein the rotation knob and locking lever are both disposed distally relative to the manual engagement section of the tool actuation lever. 7. The surgical instrument of claim 1 wherein said torque transmission member is disposed separate from and concentric with said proximal motion member. 8. The surgical instrument of claim 1 wherein the rotation knob and torque transmission member are separate from and independently operable from the proximal and distal motion members. 9. The surgical instrument of claim 1 wherein the slideable locking piece is disposed substantially along a central axis of the proximal motion member, and the torque transmission member has a length commensurate with the distance between the rotation knob and tool. 10. A surgical instrument comprising: an instrument shaft having proximal and distal ends;a tool disposed from the distal end of the instrument shaft;a control handle coupled from the proximal end of the instrument shaft and having a proximal end where the control handle is grasped and a distal end;a distal motion member for coupling the distal end of said instrument shaft to said tool;a proximal motion member for coupling the proximal end of said instrument shaft to said control handle;actuation cabling extending between said distal and proximal motion members for coupling motion of said proximal motion member to said distal motion member for controlling the positioning of said tool;said proximal motion member including at least one partially spherical element;said control handle having formed at the distal end thereof a partially spherical formed socket for receiving the at least one partially spherical element;a locking mechanism for fixing the position of the said proximal motion member at a selected position and having locked and unlocked states;said locking mechanism including a locking lever that is mounted at the control handle and movable relative to the control handle, and a slideable locking piece responsive to the manual operation of the locking lever and terminated at the proximal motion member for selectively locking a bent position of the proximal motion member to, in turn, maintain via said actuation cabling a corresponding bent position of the distal motion member;a tool actuation lever mounted at the control handle for actuating the tool and a tool actuation cable that connects the tool actuation lever to the tool;a rotation knob mounted at the control handle and rotated relative to the control handle for controlling the tool to rotate about a distal tool axis so as to control the orientation of the tool;said rotation knob mounted at the control handle and disposed between the tool actuation lever and at least a part of the proximal motion member;a torque transmission member coupled with and extending distally from the rotation knob for controlling the orientation of the tool;said tool actuation lever including a manual engagement section and a pivot for supporting the tool actuation lever from the control handle;said locking lever mounted at the control handle at a location that is spaced proximally from at least part of the proximal motion member;whereby, when the locking lever is moved to the locked state, the locking piece is slid linearly causing the partially spherical element of the proximal motion member to lockingly engage the partially spherical formed socket to thus hold the proximal motion member in the selected fixed position. 11.
