| Abstract: |
A motor driven reciprocating surgical file apparatus and method for trimming and shaping hard body materials. A small file is detachably mounted on the distal end of a reciprocating offset arm. The offset arm allows the file to be inserted and manipulated in a surgical site. The file is comprised of a slender elongated upward extending arm and an adjoining lower file portion. A plurality of teeth surround the file portion and are arranged to shape and trim bone and cartilage in a direction which is substantially parallel to the reciprocating motion of a motor's output shaft. A coupling is provided on the reciprocating arm for detachably mounting optional files. A control circuit allows a surgeon to vary the rate at which the file reciprocates. In a first aspect of the invention, the reciprocating file is driven by a battery operated electric motor. In a second aspect of the invention, the reciprocating arm is driven by an AC motor. In both aspects of the invention, a plurality of files with optional shapes and tooth arrangements are provided.

We claim:
1. A motor driven reciprocating surgical file apparatus for trimming and shaping hard body materials such as bone and cartilage comprising: a housing; a motor and drive unit mounted within said housing, said motor and drive unit having a reciprocating output shaft, said reciprocating output shaft extending outwardly from said motor and drive unit; a power supply for said motor and drive unit; a coupling at a distal end portion of said outward extending output shaft for receiving an upward extending arm of an offset file; and an offset file, said offset file having a slender elongated upward extending file arm portion for engaging said coupling and a lower adjoining file portion, said lower adjoining file portion having a plurality of teeth for shaping and trimming hard body materials in a direction which is substantially parallel to an axis of said outward extending upper portion of said motor and drive unit shaft when said offset file is mounted in said coupling.
