METHOD AND APPARATUS FOR EXTRACTION AND INSERTION OF EMBEDDED ARTICLES INCLUDING BONE-RELATED DEVICES

摘要

Method and means to remove, implant, attach and otherwise fit or adjust bone-related articles such as surgical implants, rods, nails, prosthetic and similar devices, dental restorations, and the like, without destruction of or damage to the recipient bone or composite, using a series or train of force pulses to move the article incrementally with relation to the recipient bone or composite. The waveshape of the force pulses is designed, in some cases, to oscillate the article relative to the recipient bone structure, to produce microfractures at the interface between the article and the bone or composite. A hand-held pneumatic tool is shown for providing the force pulses. The tool and method may be used for non-surgical applications such as to remove construction nails, plastic shafts, bearing races and other objects.
