Patent ID: 8512348

Claim:
A surgical tool, comprising: a handle section; a knob rotatably coupled to the handle section for rotation relative thereto and disposed proximally relative thereto; a inner drive shaft rotatably supported by the handle section and selectively longitudinally moveable relative thereto; the drive shaft rotationally fixed relative to the knob for rotation therewith relative to the handle section; the drive shaft having a drive recess at a distal end thereof; a coupling shaft rotatably supported by the handle section and selectively coupled to the knob for rotation therewith relative to the handle section; the coupling shaft disposed about the drive shaft and having an externally threaded distal section; an outer shaft extending distally from the handle section; the outer shaft supported by the handle section and fixed rotationally and longitudinally relative to the handle section; the outer shaft disposed about the coupling shaft; the outer shaft having at least one distally extending alignment flange on a distal end thereof; the tool having a first configuration wherein: the drive recess, the threaded section, and the alignment flange longitudinally overlap; the knob is rotationally decoupled from coupling shaft; the tool having a second configuration wherein: the drive shaft is retracted such that the drive recess is closer to the handle section than in the first configuration; the knob is rotationally coupled to the coupling shaft for rotation therewith relative to the handle.
