Abstract
A surgical device for cutting or shaving bone or tissue includes a housing having an elongated tube extending therefrom, the elongated tube configured to support a surgical tool at a distal end thereof. A gear assembly is disposed within the housing and is configured to control oscillation of the surgical tool. A motor is operably coupled to the housing and is configured to drive the gear assembly upon activation thereof. The motor is moveable relative to the housing to adjust one or more gears of the gear assembly which, in turn, adjusts an oscillation angle of the surgical tool to control the aggressiveness of the surgical tool when cutting tissue or bone.

1-20. (canceled)
A surgical device for cutting or shaving bone or hard tissue, comprising:
- a housing including an elongated tube extending therefrom, the elongated tube configured to support a surgical tool at a distal end thereof;
- a gear assembly disposed within the housing and configured to control oscillation of the surgical tool;
- and
- a motor operably coupled to the housing and configured to drive the gear assembly upon activation thereof,
- wherein the motor is selectively adjustable to change an oscillation frequency of the surgical tool, and
- wherein the gear assembly is moveable relative to the housing to adjust an oscillation angle of the surgical tool.
A surgical device for cutting or shaving bone or hard tissue, comprising:
- a housing including an elongated tube extending therefrom, the elongated tube configured to support a surgical tool at a distal end thereof, the surgical tool including a drive rod selectively engageable within the housing via a collet;
- a gear assembly disposed within the housing;
- and
- a motor operably coupled to the housing and operably coupled to a gear assembly, the gear assembly configured to control oscillation of the surgical tool upon activation of the motor,
- wherein selective rotation of the motor relative to the housing adjusts at least one gear of the gear assembly which, in turn, adjusts an oscillation angle of the surgical tool, and
- wherein selective movement of the collet within the housing controls a length of exposure of a tip of the surgical tool relative to a distal end of the elongated tube.
A surgical device for cutting or shaving bone or hard tissue, comprising:
- a housing including an elongated tube extending therefrom, the elongated tube configured to support a surgical tool at a distal end thereof, the surgical tool including a drive rod selectively engageable within the housing via a collet;
- a gear assembly disposed within the housing;
- and
- a motor operably coupled to the housing and operably coupled to a gear assembly, the gear assembly configured to control oscillation of the surgical tool upon activation of the motor,
- wherein selective rotation of the motor relative to the housing adjusts at least one gear of the gear assembly which, in turn, adjusts an oscillation angle of the surgical tool, and
- wherein selective movement of the collet is configured to selectively lock the drive rod of the surgical tool within the housing, the collet operably engageable with the gear assembly such that actuation of the motor oscillates the surgical tool, wherein the collet is selectively moveable within the housing to control a length of exposure of a tip of the surgical tool relative to a distal end of the elongated tube.
