Embodiment Construction
[0018] The configurations disclosed below include an articulating needle device comprising: a hinged portion of the needle and a control mechanism for selectively articulating (bending) the hinged portion. The needle adopts a cannulated (hollow) rod for passing through the actuator and pull strap. The actuator generally occupies a central region defining an axis through the interior of the cannula, and the pull strap is defined by a thin strip along the interior side closest to the serrations in the hollow rod.
[0019] The needle tip assembly is attached at the distal end of the rod and is attached (welded) to the drawstring strip. The opposite end of the pull strap is likewise welded to a lead screw at the proximal end of the tube. When rotated, the threads in the lead screw pull the strap, applying a pull on the needle tip along the serrated (cut) side of the rod, and drawing the serrated sections together to articulate the needle.
[0020] In the exemplary configuration ...
