Patent number: 7875027Abstract: Embodiments of a handle for use in a surgical tool that uses electricity is disclosed. In one embodiment, the handle is autoclaveable and reusable, and includes connections between an electrical cable (e.g. for providing electrical energy and/or transmitting electrical signals) and an operating end of the tool. An insert member having arms for stripping wire or cable electrically connects the cable and the operating end of the tool, and a set screw may be provided to hold the cable in place. A clip member may also be provided to hold the handle to the rest of the tool. Method for using and assembling handle embodiments are also described.Type: GrantFiled: April 26, 2007Date of Patent: January 25, 2011Assignee: Warsaw Orthopedic, Inc.Inventors: Julien Prevost, James P.

Publication number: 20100262200Abstract: Methods and instrumentation for vertebral interbody fusion are provided. Sleeve assemblies can be provided with a reduced width portion adjacent the distal end to limit the amount of retraction of the surrounding vascular and neural structures required for the procedure. A sleeve assembly can be provided with a guide sleeve removably engaged to a guide sleeve housing. The guide sleeve can be removed during surgery to improve the surgeon's viewing of the operative site while the guide sleeve housing maintains disc space distraction. Methods and instruments for inserting and using the guide sleeve housing are also provided.Type: ApplicationFiled: June 18, 2010Publication date: October 14, 2010Inventors: Eddie F. Ray, III, James P. Duncan
