Abstract
Abstract A scissor-like assembly having a pair of axially mating and relative slidable elongated shafts each provided with a handle and include an articulating interconnection by which the shafts are simultaneously reciprocable relative to each other and conjointly movable about their common axis. Working tool members are provided at the end of each shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
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.
Claim 2
Dependent Claim
220 words
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.
Claim 3
Dependent Claim
13 words
The surgical instrument according to claim 1, wherein said tools comprise shearing elements.
Claim 4
Dependent Claim
16 words
The surgical instrument according to claim 1, wherein said tools comprise clip holding and clamping elements.
Claim 5
Dependent Claim
33 words
The surgical instrument according to claim 1 including a second sleeve located about said shafts below said first mentioned sleeve and attached thereto to permit relative rotary movement and conjoint axial movement therewith.
