摘要：
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 member to control bending. A manually rotatable member rotates 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.
