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.
