Publication number: 20230081046Abstract: Kits and methods for use in intraoperative trialling of hip prostheses to determine an appropriate length for the femoral neck component of a prosthetic hip joint, are described. A kit for use in selecting a femoral neck component of an orthopaedic joint prosthesis kit comprises a first and a second broach. Each of the first and second broaches has a neck connection element comprising a projection extending from a proximal surface of the broach, each projection having a length. The projection on the first broach has a different length than the projection on the second broach. The kit also includes a trial femoral neck component having a neck connection element in the form of a recess in a distal surface.Type: ApplicationFiled: May 24, 2022Publication date: March 16, 2023Inventors: David HORNE, Thomas MAACK, Jeffrey MCANELLY, Stephanie PRINCE, James Aaron REED, Duncan YOUNG

Patent number: 11369492Abstract: Kits and methods for use in intraoperative trailing of hip prostheses to determine an appropriate length for the femoral neck component of a prosthetic hip joint, are described. A kit for use in selecting a femoral neck component of an orthopaedic joint prosthesis kit comprises a first (10) and a second (110) broach. Each of the first and second broaches has a neck connection element comprising a projection (12, 112) extending from a proximal surface (14, 114) of the broach, each projection having a length (L). The projection on the first broach has a different length than the projection on the second broach. The kit also includes a trial femoral neck (30) component having a neck connection element in the form of a recess (36) in a distal surface (34).Type: GrantFiled: July 27, 2018Date of Patent: June 28, 2022Assignee: DePuy Ireland Unlimited CompanyInventors: David Horne, Thomas Maack, Jeffrey McAnelly, Stephanie Prince, James Aaron Reed, Duncan Young

Patent number: 11160566Abstract: A surgical rotational cutting tool, a surgical kit and a method of preparing a femur to receive a stem of a femoral prosthetic. The tool includes a longitudinal axis and a shaft extending along the longitudinal axis, which has a proximal end and a distal end. The tool also includes a head located at the distal end of the shaft. The head includes a pointed distal tip, a bone contacting outer surface having a portion which curves inwards toward the longitudinal axis as it approaches the tip, and a plurality of flutes. The edges of distal parts of neighboring pairs of the flutes meet to define a plurality of cutting edges which extend proximally from the pointed distal tip. A proximal part of each flute extends proximally across the curved portion.Type: GrantFiled: January 24, 2018Date of Patent: November 2, 2021Inventors: Alec Birkbeck, Graeme Dutton, David Horne, Thomas Maack, Richard Patnelli

Patent number: 10849765Abstract: The invention provides an impactor for transmitting an assembly force to a component of an orthopaedic implant. The impactor has first and second telescoping parts which are biased apart by means of a main spring. The main spring is compressed when an assembly force is applied to the parts. An indicator is latched against movement until it is released when the extent of the compression of the main spring by the application of an assembly force exceeds a threshold. The indicator then moves to provide the user with an indication that a minimum assembly force has been applied.Type: GrantFiled: April 12, 2017Date of Patent: December 1, 2020Inventors: Alec Birkbeck, Graeme Dutton, David Horne, Thomas Maack, Gary Moore

Patent number: 10695076Abstract: The invention provides an osteotome which includes a curved guide member extending distally from its medial side. This curved guide member interfaces with the medial curvature of the femoral canal. The guide member guides the osteotome using the internal bone geometry of the femoral canal instead of relying on external anatomical landmarks.Type: GrantFiled: March 29, 2017Date of Patent: June 30, 2020Assignee: DEPUY IRELAND UNLIMITED COMPANYInventors: Marcus Agunloye, Alec Birkbeck, Graeme Dutton, David Horne, Thomas Maack, John Bohannon Mason, Richard Patnelli

Patent number: 9581888Abstract: A projection apparatus includes an image-producing element and projection optics. The image-producing element produces at least one image, and the projection optics has free-form areas for magnifying and reflecting the image toward an viewer for observation. The projection optics includes at least a first mirror and a second mirror, the image is reflected by the first mirror and the second mirror in succession, no deflection mirror is disposed between the viewer and the second mirror, and the first mirror and the second mirror are in the form of a non-rotationally symmetrical system.Type: GrantFiled: February 19, 2015Date of Patent: February 28, 2017Assignee: YOUNG OPTICS INC.Inventors: Eberhard Piehler, Gudran Schroeter, Guenther Benedix, Gertrud Blei, Thomas Maack

Patent number: 8992025Abstract: The invention relates to a rear project device, comprising a screen, projection optics, and an image module for generating an image, which is projected from the rear onto the screen by means of the projection optics, so that an observer located in front of the screen can perceive the image projected onto the screen. Furthermore, a method for such a rear projection apparatus is described. To this end, a Fresnel mirror, or an aspherical mirror, is used.Type: GrantFiled: January 25, 2008Date of Patent: March 31, 2015Assignee: Young Optics Inc.Inventors: Eberhard Piehler, Gudrun Schroeter, Guenther Benedix, Gertrud Blei, Thomas Maack
