Publication number: 20230248538Abstract: Technologies for aligning an acetabular prosthetic component in a patient's surgically prepared acetabulum include a reference sensor module securable to the patient's bony anatomy, an inserter sensor module securable to an acetabular prosthetic component inserter, and a display module. Each sensor module generates sensor data indicative of the orientation of the sensor module and/or structures to which the sensor module is coupled. The display module receives the sensor data from the sensor modules, determines the orientation of the acetabular prosthetic component relative to the patient's bony anatomy, and displays indicia of the determined orientation on a display.Type: ApplicationFiled: April 19, 2023Publication date: August 10, 2023Inventors: Jason T.

Publication number: 20220125543Abstract: Surgical instrument trays and related methods are described. The surgical instrument tray is for a surgical instrument having a plurality of parts from which the surgical instrument is assembled. The surgical tray comprises a tray having a plurality of side walls and a base which define an interior space; a lid for closing the interior space and which is removable from the tray; and a plurality of outlines located within the interior space. Each outline has the shape of a corresponding different part of the surgical instrument and each outline has at least one support arranged to receive and releasably hold the respective different parts of the surgical instrument above and in registration with the outline. The plurality of outlines are configured to indicate that the different parts of the surgical instrument are assembled to form the surgical instrument and/or that the surgical instrument is disassembled into the different parts.Type: ApplicationFiled: October 4, 2019Publication date: April 28, 2022Inventors: ALEC BIRKBECK, SARAH BUSHELL, DUNCAN YOUNG

Patent number: 11213301Abstract: The invention provides a reamer handle comprising: a shank having a distal tool coupling end adapted to releasably couple to a part of a surgical tool and a proximal end; a retractable catch which is linearly displaceable along the shank between a non-retracted position in which the catch captures the surgical tool within the distal tool coupling end of the tool holder and a retracted position in which the catch enables the tool to be released from the distal tool coupling end; a biasing member configured to bias the catch in the non-retracted position; and a sleeve extending along the shank. The sleeve comprises: a distally located catch contacting portion and a proximally located handle portion for manually displacing the sleeve relative to the shank such that displacement of the catch contacting portion moves the retractable catch between the non-retracted position and the retracted position to enable capture and release of the tool from the tool holder.Type: GrantFiled: June 26, 2018Date of Patent: January 4, 2022Assignee: DePuy Ireland Unlimited CompanyInventors: James Anderson, Alec Birkbeck, Ian Flatters, David Horne

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

Publication number: 20210275313Abstract: An orthopaedic joint prosthesis assembly includes a head part of an orthopaedic joint prosthesis component and an alignment guide. The head part has a spherical bearing. surface for articulation with a corresponding joint surface, and an assembly surface having a first bore formed in it for receiving a spigot on another part of the orthopaedic joint prosthesis, The bore has a first axis that extends perpendicular to the assembly surface. There is a discontinuity at an interface between the bearing surface and the assembly surface, and the assembly surface is arranged on a plane which is parallel to, or contains, a plane which is defined by the opening to the bore in the head part when the head part is viewed from one side in cross-section. The alignment guide has an axial portion and an arm extending from the axial portion.Type: ApplicationFiled: May 25, 2021Publication date: September 9, 2021Inventors: Gary MOORE, Alec BIRKBECK, Christopher HUNT, Richard PATNELLI, David HORNE, Henry PROUT

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
