US Patent 8702709 Intervertebral disc reamer

An intervertebral disc reamer includes a flexible shaft having a shaft channel, and a reamer head attached to the flexible shaft and movable relative to the flexible shaft. The reamer head has a reamer channel. The shaft channel and the reamer channel are aligned to define a continuous guide wire channel for the disc reamer. The disc reamer addresses the quality of disc removal and endplate preparation, minimizes the trauma of surgery, minimizes blood loss, and markedly reduces surgical time.
