Patent number: 11583296Abstract: A femoral head guide clamp can include jaws and two opposing arms that extend from the jaws. The jaws can include an aperture shaped such that the jaws have a closed position in which the aperture fits around a femoral neck of a patient but is too small to accept a femoral head of a patient, and an open position in which the aperture is expanded such that it is large enough to allow the femoral head to pass through. The arms can include a proximal section in which the arms are substantially parallel in a side-by-side arrangement, and a distal section in which the arms extend away from each other such that moving the two distal sections towards each other moves the jaws towards the open position.Type: GrantFiled: December 12, 2018Date of Patent: February 21, 2023Assignee: Embody Orthopaedic LimitedInventor: Robert Michael Wozencroft

Patent number: 11382767Abstract: An acetabular cup guide can include a distal end (11) shaped to allow removable connection to a surgical instrument (16), a proximal end including one or more contact surfaces (4, 5) shaped to conform to an acetabulum, and a central proximal-distal axis extending through the acetabular cup guide. At least one of the one or more contact surfaces can be configured such that it is deflectable towards the central proximal-distal axis in order to reduce an axial cross-section of the acetabular cup guide.Type: GrantFiled: December 8, 2018Date of Patent: July 12, 2022Assignee: Embody Orthopaedic LimitedInventor: Robert Michael Wozencroft

Patent number: 9242053Abstract: An autoinjection device has front and rear separable assemblies (10) and (12). The rear assembly contains a drive assembly which is triggered or unlatched by rearward movement of an actuating sleeve (14) extending from the front assembly. A locking dial (16) is provided which locks the actuating sleeve against rearward movement until the dial is moved to an unlocked position. The dial automatically returns to a locked position upon initial rearward movement of the actuating member (14), so that, when the actuating member (14) moves forwardly after completion of an injection, it locks out to shroud the needle of the autoinjection device. The docking dial can be made integral with the actuating member (14) in an alternative embodiment.Type: GrantFiled: August 28, 2009Date of Patent: January 26, 2016Assignee: OWEN MUMFORD LIMITEDInventor: Robert Michael Wozencroft
