Abstract
A bone morselization apparatus and method according to which a cutter bit is mounted to a casing containing a motor; and the casing is manually grasped and positioned over a plurality of bone segments. When the motor is activated, the cutter bit reciprocates and the bone segments are impacted by the cutter bit to morselize the segments.
Claims18
An apparatus for morselizing bone segments, the apparatus comprising:
- a casing;
- a motor disposed in the casing and having a reciprocal output;
- and
- a cutter bit coupled to the motor so as to reciprocate when driven by the motor to impact and morselize the segments.
