Abstract

Disclosed herein are embodiments of a flexible connecting shaft for an intramedullary reamer. In each embodiment, several short segments or links are attached together to form an elongated flexible shaft which shaft is designed, due to the specific attachment means for the links, to bend along its longitudinal axis while transmitting torque without any lag in such transmission. A link at one end of the flexible shaft as made by a plurality of the links includes means provided for attachment to a torque providing device such as an electric motor. At the opposite end of the shaft, the last link includes structure thereon enabling connection to a drill bit. The various embodiments disclose different ways of interconnecting the links.
