ORTHOPEDIC DRIVER INSTRUMENT AND METHODS OF PRODUCTION

摘要

An orthopedic driver instrument including a metal injection molded driver bit having an overall bit length, and a plastic injection molded handle having an overall handle length at least twice the overall bit length, the handle including a gripping portion and an elongate shaft portion over molded about a shank portion of the driver bit. A method of producing an orthopedic driver instrument is also provided including forming a metallic driver bit using a metal injection molding process, and forming a plastic handle using a plastic injection molding process, wherein the plastic handle has a gripping portion and an elongate shaft portion, and the plastic injection molding process comprises over molding the elongate shaft portion of the plastic handle about a shank portion of the metallic driver bit. In some embodiments, the overall length of the plastic handle is at least twice the overall length of the metallic driver bit.
