The surgical instrument includes a distal tool, an 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. The proximal bendable member comprises a ball and socket assembly supported between the handle and instrument shaft and constructed and arranged for three dimensional motion.
A medical instrument comprising:
A medical instrument having a proximal control handle and a distal tool that are intercoupled by an elongated instrument shaft that is meant to pass internally of an anatomic body, proximal and distal movable members that respectively intercouple said proximal control handle and said distal tool with said instrument shaft, cable actuation means disposed between said movable members and a rotation ball and wherein said control handle comprises a base and a section that defines a spherical socket that supports the rotation ball for multi dimensional pivoting therein;
A surgical instrument comprising:
A medical instrument comprising a proximal control handle that includes proximal and distal ends and a distal tool that are intercoupled by an elongated instrument shaft that is meant to pass internally of an anatomic body and that includes proximal and distal instrument shaft ends, proximal and distal movable members that respectively intercouple said proximal control handle with the proximal end of the instrument shaft and said distal tool with the distal end of said instrument shaft, actuation cabling that is disposed between said movable members so that a movement of said proximal movable member causes a corresponding movement of said distal movable member and distal tool, said proximal movable member comprised of an at least partially spherically shaped ball that is attached to the proximal end of the instrument shaft and a socket that is defined in the distal end of the control handle, said ball and socket constructed and arranged for relative motion therebetween in multiple dimensions, a rotation knob rotatable relative to the control handle for causing a corresponding rotation of the distal tool about a distal tool roll axis, and a locking mechanism having locked and unlocked states and that fixes the relative position between the ball and socket, said rotation knob being disposed adjacent said locking mechanism.
