  • Patent number: 7875027
    Abstract: 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.

  • Publication number: 20100262200
    Abstract: 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.

  • Patent number: 7578820
    Abstract: Methods and instruments are provided for performing spinal disc space preparation and implant insertion in minimally invasive procedures. The instruments include cutting instruments and implant insertion instruments adapted for insertion through a minimally invasive access portal to a spinal disc space. The proximal portions of the instruments are adapted to facilitate viewing through a proximal end opening of the access portal with the instruments positioned through the access portal while also enhancing the surgeon's control of the distal working end of the instruments while in the disc space.

  • Publication number: 20040176775
    Abstract: Methods and instrumentation particularly adapted for disc space preparation for insertion of implants from an anterior approach to the spine are provided. The instruments include a guide sleeve defining a channel having overlapping cylindrical working channel portions and lateral non-distracting extensions extending from reduced thickness wall portions. The guide sleeve has an overall reduced width configuration. A pair of distractors are provided. A first distractor includes a shaft and distal tip, and the second distractor includes a shaft and distal tip. The first and second distractors can be used with the guide sleeve. Methods using the disclosed instruments are also provided.
