Abstract: A disposable wire driver for inserting wires into or through bones to provide support and fixation for the bone while the bone structure is mending. As unused, the wire driver is enclosed in a sterility-preserving wrapper that protects the wire driver until it is ready for use. The wire driver is disposable after a single use and is constructed largely of plastic. The wire driver includes an elongated, plastic casing having a front opening at a front end of the casing, and a back opening at a back end of the casing. A wire passageway extends through the casing from the back opening to the front opening to allow a wire to be inserted into the back opening and through the wire driver. The casing encloses a motor and a battery coupled to the motor. The battery-powered motor drives a pinion-and-gear assembly which is connected to a wire holding tube. The collet extends through the front opening of the casing and selectively grips a wire inserted into the wire driver.
