Abstract
A portable surgical wire inserting instrument comprising a housing defining a handle and a head casing. The housing handle holds a removable power pack in which is mounted a motor and a source of power electrically connected to the motor. A miter gear extends from the power pack and is connected by a drive shaft to the motor. A collet is mounted in the housing and is selectively adjusted to grip a plurality of different diameter surgical wires through the action of a knob and cam mechanism located on top of the instrument head. Rotation of the knob to one of a number of different positions establishes a number of different positions for the pivot points of thrust bars which act upon pins to draw the collet into an internally coned tube. Each position corresponds to a location of the thrust bar pivots suitable for gripping wires of different sizes. Gripping of the wire is accomplished by rotating a cam which moves the thrust bars rearward against pins which move a draw tube rearward and further draws the collet into the internally coned tube causing the jaws of the collet to squeeze in and grip the surgical wire. A miter gear on the coned tube connects with the miter gear extending …
