Osteotome handpiece driven by compressed gas for surgery
The patent US12029437B1 describes an innovative osteotome designed for surgical applications, featuring a blade capable of cutting materials. Central to its operation is a drive mechanism that can either transmit force to a force-transmitting component or directly to the blade. This mechanism includes a cylinder with a liner made from a specific material, and a spherical piston that moves within this liner. Notably, the design emphasizes low friction, with the coefficient of sliding friction between the cylinder liner and piston materials being less than 0.20. Additionally, the internal surface of the cylinder liner must have a surface roughness of 125 microinches rms or smoother, while the spherical piston has a roughness between 5 and 20 microinches rms. The patent also outlines various configurations and materials for the cylinder liner, including fluoropolymers and specific additives to enhance performance.
Further claims detail the structural components of the osteotome, including a piston return spring and a piston washer designed to facilitate the movement of the spherical piston. The piston washer features a concave surface that interacts with the spherical piston, allowing for effective force transmission to the blade. The design also includes a retaining collar that secures a second piston, which is part of a dual-cylinder system, enhancing the osteotome's functionality. The retaining collar is threaded and designed to accommodate the second piston, ensuring a secure grip on the blade. Overall, the patent presents a comprehensive design aimed at improving the efficiency and effectiveness of surgical cutting instruments through advanced engineering and material selection.
