Patent number: 10159500Abstract: An oscillating surgical rasp for use in the surgical preparation of a glenoid of a patient prior to implantation of an augmented glenoid prosthesis comprises an attachment head and a cutting head secured to the attachment head. The attachment head has a body that extends along a longitudinal axis from a first end configured to be secured in a chuck of an oscillating tool to a second end secured to the cutting head. The first end of the body of the attachment head defines an axis of oscillation that extends orthogonal to the longitudinal axis of the oscillating surgical rasp. Surgical methods for the use of such oscillating rasps are also disclosed.Type: GrantFiled: January 4, 2018Date of Patent: December 25, 2018Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Jason M. Chavarria, Matthew T. Stone

Patent number: 9861376Abstract: A method of surgically implanting a glenoid component into the glenoid of a patient is disclosed. The method includes securing a rasp guide into the glenoid of the patient. The method also includes oscillating a surgical rasp over the rasp guide to form a cavity that is shaped to receive the glenoid component. The method also includes implanting the glenoid component in the cavity.Type: GrantFiled: July 27, 2015Date of Patent: January 9, 2018Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Jason M. Chavarria, Matthew T. Stone

Publication number: 20140341659Abstract: A half-round file attachment for a saw comprising a blade that extends the length of the half-round file attachment, the blade includes a first end and a second end; a connection at the first end, where the connection fastens the blade to the saw; a flat side of the blade, where a surface of the flat side is covered with a plurality of sharp parallel teeth to remove small amounts of material from work piece; and a rounded side on an opposite side of the blade from the flat side, where a surface of the rounded side is also covered with the plurality of sharp parallel teeth. The blade is tapered to enable filing of work pieces of various sizes.Type: ApplicationFiled: May 14, 2013Publication date: November 20, 2014Inventor: Russell Harrell

Patent number: 8678715Abstract: An abrading wheel such as a rasp hub for use in tire retreading machines includes two generally circular end, or side, plates with plural spaced mounting pins extending between and coupled to the two spaced plates. Rasp blades arranged in stacks which are arranged end-to-end about the wheel's circular circumference. Disposed between and engaging each pair of adjacent blades is a spacer, which is also attached to the mounting pins. Each spacer is curved lengthwise to match the curvature of the blades and includes plural spaced upper and lower recesses disposed immediately adjacent to its pair of adjacent blades to allow air to freely pass over the entire length of each blade as the hub is rotated at high speed to dissipate heat from the blades during operation for increased blade reliability and longevity.Type: GrantFiled: November 15, 2010Date of Patent: March 25, 2014Assignee: B&J Rocket America, Inc.Inventor: Stanley D. Jones

Patent number: 7959495Abstract: A method and apparatus for finishing the surface of rubber or synthetic covered rollers (10) is disclosed. As seen in FIG. 3, a rotating hub (16) having a circumferential abrasion band (47) and an adjacent set of rasp blades (20) arranged end-to-end and extending circumferentially about the hub is used to progressively and sequentially removebands of surface material by cutting and then abrading as the hub and roller are rotated and one is moved axially relative to the other.Type: GrantFiled: October 18, 2007Date of Patent: June 14, 2011Assignee: B&J Rocket America Inc.Inventor: Charles K. Stanfield

Publication number: 20090071297Abstract: A file guide is provided having a tubular handle, a spindle, and a retainer. The tubular handle has a central bore with an inner bearing surface and an outer gripping surface. The spindle has a cylindrical outer bearing surface configured to mate in complementary, rotatable relation with the inner bearing surface of the handle, a head at a proximal end, a lock portion at a distal end, and a central receptacle configured to receive a file shank.Type: ApplicationFiled: September 17, 2007Publication date: March 19, 2009Inventor: Jere F. Irwin

Patent number: 7341407Abstract: A tire rasp blade made with an arcuate shape having a planar body with cutting teeth at the outer working edge. The cutting teeth extend laterally relative to the planar body in alternating sets of curved sections. The curved sections preferably form a sinusoidal curve along the outer working edge. The tire rasp blade is made by initially forming an arcuate blade of planar material that has an outer periphery of varying radii from a center point of the arcuate blade; then cutting teeth are formed at the varying radii of the working edge of the planar material; and then an outer portion of the planar material is deformed laterally in opposite directions to form alternating, oppositely curved sections, with the cutting teeth all lying approximately at the same circumferential radius so that they all contact the tire to be buffed.Type: GrantFiled: January 7, 2004Date of Patent: March 11, 2008Assignee: Pincott International Pty. Ltd.Inventor: Noel Harold Boorer

Patent number: 6678909Abstract: A multifunctional device for removing material from an edge of an object and lifting an object from a support surface is provided. The device includes front and rear portions that are positioned at an angle relative to one another to form a pivot point. The front portion is positioned beneath the object while a user applies a downward force on the rear portion to rotate the device about the pivot point to lift the object from the surface. A pair of opposed sidewalls extend from an upper surface of the device and a top wall is coupled between the sidewalls to form a channel. At least one protrusion extends from the top wall into the channel to remove material from the edge. In addition, a tab may extend into an aperture formed in the rear portion to engage and assist in the removal of a lid from a bottle.Type: GrantFiled: August 14, 2002Date of Patent: January 20, 2004Assignee: Marshalltown CompanyInventor: Georgia Pyatt

Patent number: 6494647Abstract: Curved file apparatus includes a base element having a straight file on a top surface and a curved element secured to the base element. The curved element includes a convex bottom file surface and a pair of flat file surfaces on the sides of the curved element. The curved element may stand aloe in a second embodiment, with its convex file surface and its flat file surfaces. Handle elements are secured to both embodiments.Type: GrantFiled: June 10, 1999Date of Patent: December 17, 2002Inventor: Ronald D. Schritz
