Abstract:
1. A surgical file instrument comprising a tubular casing supporting a reciprocating surgical file, said reciprocating surgical file having a blade at the distal end and a tang at its opposite end, a solid tubular member supported in said tubular casing having an elongated lumen for receiving said reciprocating surgical file wherein said blade is located at the distal end thereof and projects there-beyond and said tang is located at the proximal end thereof and projects there-beyond, a motion converter comprising a split housing, said motion converter including means in said split housing for converting rotary motion to reciprocal motion, a rotary motor in said split housing, said means including a planetary gear system driven by said motor, a drum, a cam having a cam slot operatively connect to said planetary gear system and a cam follower attached to the outer periphery of said drum wherein the cam rotated by the planetary gear system rotary positions the cam slot such that the cam follower imparts reciprocal motion to said drum, a shaft attached to one end of said drum and being attached to said tang for imparting reciprocal motion to said blade, and a source of power for powering said motor for causing said blade to reciprocate.
