A system and method for improving installation of a prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation.

A system and method for improving installation of a prosthesis, particularly an acetabular cup. The system and method may include implementation of a constant velocity relative motion between a prosthesis and an installation site. For example, an installation system may be fixed relative to the installation site, with the prosthesis fixed into an initial position. The prosthesis is moved at constant speed (i.e., with minimal if any acceleration or applied impulses) relative to the installation site. That is, one or both of the prosthesis or the installation site may be in motion. Resistive forces to installation of a prosthesis may thus be reduced by maintaining the prosthesis constantly in motion relative to the installation site. Securing a processing / implanting tool directly to the installation site may offer advantages.

The invention relates to a method for processing the high-speed deformation on the surface of metallic material with nano structure, and particularly provides a method for realizing high-speed processing of the organization structure of ultra-fine grains. On the condition of room temperature or low temperature, by adopting a mechanical treatment method with high-speed plastic deformation, the nanoscale bulky crystalline grain structure on the surface layer of the metallic material is refined as equiaxial submicron crystalline grain or nano crystalline grain to form an ultra-fine organization structure of the crystalline grain on the surface layer of the metallic material.

The median frequency in the emission from a microwave generator (14), which operates in a pulsed manner, is shifted when the generator (14) operates between passive reflectors (23) whose axes are parallel thereto. In the axial direction, the reflectors (23) are approximately the same length (L) as the generator (14), with length matching through telescopic rods being preferable. However, the frequency is governed primarily by the distance (D) between the reflectors (23-23) between which the generator (14) is operated. Once desired resonance conditions have been found, for example for injection of microwave radiation into the mechanical structure of an external arrangement, this frequency relationship can be fixed by the magnitude of the length of the preferably telescopic coupling piece (16) between the resonator (13) and the antenna (18).
