US Patent 7922726 Surgical tool handle and disposable broach assembly

A surgical tool handle and separate disposable orthopedic tool head assembly is disclosed. The surgical tool handle has a reinforcing member extending from it. The reinforcing member is receivable in an internal bore of the disposable orthopedic tool head and provides structural reinforcement for the tool head. This reinforcement allows the use of disposable materials in the construction of the tool head that otherwise could not be use (e.g., plastic and resin materials) because of an increased risk of breakage or failure relative to metallic tool heads.
