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. 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.
