Patent number: 9198672Abstract: The disclosure illustrates a dual driver for surgical reamers in which either of a crossbridge and crossbar style reamers are axially inserted in the distal end of a central shaft for the reamer driver. A pair of L shaped grips are adapted to connect and disconnect the different style of reamers by the movement of an external sleeve biased towards the connection position. Movement of the sleeve away from the distal end allows an internal plunger to cam the grips to an open position and urge the appropriate reamer from the tool driver directly in an axial direction.Type: GrantFiled: March 18, 2013Date of Patent: December 1, 2015Assignee: Symmetry Medical Manufacturing, Inc.Inventor: Stuart Weekes
