Abstract

A forceps comprising: (a) a stylet comprising; (i) a hollow tube having a longitudinal axis; (ii) assemblies, that are extendable through the hollow tube, comprising; (1) support rods; (2) functional attachments at the end of the support rods; (b) a hand piece comprising; (i) housing structures defining a cavity that houses the stylet; (ii) actuating mechanisms, in communication with the stylet, comprising; (1) a bearing fitting located on the stylet; (2) a shuttle in communication with the bearing fitting, and constrained by a plurality of guide ridges so that the shuttle is movable along a longitudinal axis and restricted from rotational movement around the longitudinal axis; (3) a socket housed by the shuttle, the socket receiving the bearing fitting and being rotatable relative to the shuttle; and (4) levers in communication with the stylet that causes movement of the hollow tube and the assemblies are relative to each other.
