Patent number: 8858346Abstract: A faceted bone screw and a method for manufacturing the same includes a screw thread configuration having facets that are substantially transverse to the thread. The facets are generally made up of a plurality of transitioning peaks and valleys which vary the depth of the thread and are disposed in one or more locations throughout the threaded portion of the bone screw. The facets operate to reduce the torque required to drive the bone screw into bone, while at the same time operate to assist in anchoring the bone screw within the bone once inserted therein, and thereby reduce the possibility for the screw backing out after insertion.Type: GrantFiled: January 6, 2012Date of Patent: October 14, 2014Assignee: Medical Facets LLCInventors: Wayne A. Willert, Glenn A. Rupp, Kevin J. Lovell

Publication number: 20070233154Abstract: A broken intramedullary rod removal tool for extracting the distal end of a broken intramedullary rod from bone in which it is embedded. In a first embodiment the tool has an extraction shaft, an expansion rod disposed and longitudinally movable within the shaft, a strike plate adapter secured to the proximal end of the extraction shaft, a thumb screw secured to the strike plate adapter, and a strike plate secured to the strike plate adapter. The distal end of the extraction shaft is inwardly tapered and has a split-bulb tip, so that the expansion shaft distal end can be flared out by insertion of the distal end of the expansion shaft therein, to expand the tip so that it engages the distal end of the broken intramedullary rod, thus permitting the distal portion of the broken rod to be removed by striking the strike plate to force out the expansion shaft and tip-engaged broken rod end.Type: ApplicationFiled: February 8, 2007Publication date: October 4, 2007Inventors: Shreedhar Kale, Matthew C.

Patent number: 6464588Abstract: A flexible shaft having at least one end formed to have a helical square shape, wherein successive cross-sections have square shapes progressively rotated with respect to each other. The overall rotation from where the square cross-section begins to the adjacent end of the shaft is preferably in the range of 10 to 20 degrees. The helical square end is preferably shaped by swaging utilizing helical square dies preferably made by electron discharge machining. When the helical square end of the flexible shaft is forced into a mating square opening of an end fitting, the helical square configuration of the shaft end causes it to be deformed and bind tightly in the fitting with an interference fit, thus reducing vibration and noise when the shaft is rotated. Instead of a helical square shape, the end of the flexible shaft may alternatively have another helical polygonal shape.Type: GrantFiled: August 30, 2000Date of Patent: October 15, 2002Assignee: S. S. White Technologies Inc.Inventor: Glenn A. Rupp

Patent number: 5720749Abstract: A medullary rotational reaming apparatus includes an elongated, flexible, hollow, tubular shaft formed of a nickel-titanium alloy and having coupling portions at the opposite ends thereof. Each of a cutter head and a rotational drive coupling element has a hollow tubular coupling shank, each shank having a coupling inner surface which is quadrilobular in transverse cross section and is dimensioned to prevent free reception of a coupling portion of the shaft therein. The coupling portions of the shaft are axially press-fitted in permanent engagement, respectively, within the shanks of the cutter head and the drive coupling element, with said coupling portions being permanently deformed to the transverse cross section of the coupling inner surface of the shanks, thereby to fix the cutter head and the coupling element to the shaft solely by the press-fitted engagement of the coupling portions in the shanks.Type: GrantFiled: March 18, 1996Date of Patent: February 24, 1998Assignee: Snap-on Technologies, Inc.Inventor: Glenn A.
