Abstract:
A bone fixation pin is inserted into a bone with an apparatus comprising a housing having a proximal portion and a distal portion, the distal portion having an inner surface and an opening configured to receive the bone fixation pin; a drive shaft having a proximal end configured to engage a handle and a distal end; and a body having an axis and a peripheral edge. The body comprises a bore along the axis, the bore being configured to slidably engage the distal end of the drive shaft; and a plurality of evenly spaced slots in the peripheral edge of the body. A plurality of chuck arms move radially along the evenly spaced slots in the peripheral edge of the body, each chuck arm having an inner surface and an outer surface. The distal end of the drive shaft and the body are within the proximal portion of the housing, the body being biased toward the distal end of the housing; and the inner surface of each chuck arm is configured to engage the bone fixation pin. The outer surface of each chuck arm slidably engages the inner surface of the housing.
