ABSTRACT:
A coupling device and method of coupling especially suitable for coupling multiple components of surgical instruments are provided. A wedging portion provides an interference fit between parts so that a secure connection can be made that will not unintentionally dissociate. In a preferred embodiment, bores and counterbores within dovetail portions are provided. Especially preferred is the use of this coupling device to secure a reamer head to a shaft.
