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 specifies various materials for the cylinder liner, including fluoropolymers, and outlines structural features such as wall thickness and diametral clearance.
Further claims expand on the osteotome's design, detailing components like a piston return spring and a piston washer that enhances the mechanism's functionality. The piston washer is designed with a concave surface to accommodate the spherical piston, allowing for effective force transmission. The osteotome can be driven by compressed gas, and its construction includes a second cylinder and piston arrangement that facilitates the gripping of the blade. The retaining collar, which secures the narrower region of the force-transmitting component, is designed with a threaded structure for stability. Overall, the patent outlines a sophisticated surgical tool that combines advanced materials and engineering to improve surgical cutting efficiency and precision.
