Patent number: 7984838Abstract: A system for use in a surgical procedure comprising a pneumatic instrument having an inlet and an outlet, a tank fluidly coupled to the inlet of the pneumatic instrument, wherein the tank provides pressurized helium gas to power the pneumatic instrument, and a compressor fluidly coupled to the outlet of the pneumatic instrument. The compressor receives the helium gas exhausted from the pneumatic instrument and compresses the exhausted helium gas to supply the tank with pressurized helium gas.Type: GrantFiled: May 4, 2006Date of Patent: July 26, 2011Assignee: Medtronic PS Medical, Inc.Inventors: Rex Wesley Shores, Gabriel A. Johnston, Robert L. Woods

Patent number: 7066940Abstract: A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and a male member carried by the spindle. The spindle includes a cavity. The dissection tool is releasably received in the cavity. The dissection tool extends along an axis and includes a first end and a second end with the first end having a cutting element and a second end having a generally cylindrical cross-section and a centrally located aperture partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool.Type: GrantFiled: March 21, 2002Date of Patent: June 27, 2006Assignee: Medtronic, Inc.Inventors: Danny C.

Patent number: 7001391Abstract: A surgical instrument for the dissection of bone and other tissue includes a spindle, a dissection tool and an adaptor disposed between the spindle and the dissection tool. The spindle includes a cavity and a male member projecting into the cavity. The adaptor includes a drive shaft that extends along an axis and includes a first end having a generally cylindrical cross-section and a centrally located aperture partially extending along the axis. The male member is carried by the spindle and extends into the aperture of the dissection tool. The cavity may define a drive portion and a tool receiving aperture. One or more alignment projections may extend from the drive portion into the tool receiving aperture.Type: GrantFiled: July 22, 2002Date of Patent: February 21, 2006Assignee: Medtronic, Inc.Inventors: Larry Dale Estes, Danny C.

Publication number: 20040186479Abstract: A surgical instrument is provided for cutting bone and other tissue. The surgical instrument includes a motor assembly, a collet, a locking nut, and an attachment. The motor assembly includes a cavity having a groove on an inner surface that corresponds to a groove on an outer surface of the collet. The corresponding grooves form an aperture when the collet is inserted into the cavity. The insertion of a pin into the aperture prevents rotation of the collet relative to the cavity. The locking nut is placed over the collet and fastened to the motor assembly to secure the collet to the motor assembly. The attachment is fastened to the collet by placing protuberances on the attachment into corresponding apertures on the collet. The consistent alignment provided by the locking and indexing system enables the motor assembly and attachment to receive alignment markings before the surgical instrument is assembled.Type: ApplicationFiled: April 6, 2004Publication date: September 23, 2004Applicant: Medtronic, Inc. d/b/a Medtronic Midas RexInventors: Durrell G. Tidwell, Rex Wesley Shores
