Surgical instrument

A surgical instrument comprising a pair of axially matable and relatively slidable shafts each having at their distal ends cooperating working tools, a sleeve mounted adjacent the proximal end of said shafts, one of said shafts being fixedly attached to said sleeve for conjoint movement therewith, the other of said shafts extending freely through said sleeve and being exposed at its proximal end, a pair of handle members pivotally attached to each other and arranged scissor-like for manipulation by one hand, one of said handles being attached to said sleeve for conjoint axial movement and relative free rotary movement therewith, said sleeve and said one handle being arranged so that said sleeve is manipulatable by a finger of the same hand simultaneous with the manipulation of said handle, a radially enlarged wheel on said sleeve and said wheel and said one handle having a cooperating detent mechanism defining the conjoint rotation of said shafts in predetermined intervals, said other handle being universally attached to the exposed proximal end of said freely extending shaft, said shafts being caused to reciprocate relative to each other on manipulation of said handle members and to rotate about their common axis by manipulation of said sleeve, whereby said tools may be operated and moved into selected rotary positions relative to the axis of said shafts.
