  • Patent number: 11583296
    Abstract: 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.

  • Patent number: 11382767
    Abstract: 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.

  • Patent number: 11058555
    Abstract: The present invention is directed to a system comprising a medical instrument (e.g. cup implant, 3) and a holding device (2) that interacts with said medical instrument to form a sealable cavity within the combined arrangement of components. An impaction device (1) is also provided, preferably which provides means to allow fluid to be expelled from the cavity but which prevents further fluid from entering the cavity.

  • Patent number: 9440026
    Abstract: An autoinjection device includes a main body in the front end of which is slideably mounted a drawer or front body portion. The drawer can be opened to remove or insert a syringe. Closing the drawer while pressing a multifunction button primes the drive mechanism by latching it against trigger latch. Pressing the button gain while urging the front end causes the drawer to release the trigger latch. After the injection the drawer shrouds the used needle and can be released only by pressing the button.

  • Patent number: 9242053
    Abstract: 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.

  • Publication number: 20150250409
    Abstract: A lancing device includes a housing (10, 12) for receiving in use a replaceable lancet (34) introduced into said housing, a drive (58, 59) actuable to drive the lancet momentarily to project its tip from the housing, and a nose portion (14) having an aperture through which said lancet projects when fired. The nose portion is threadedly engaged (78, 81) with the forward end (10) of the housing to allow the penetration depth of said lancet tip to be pre-set, and is resiliently deformable between a position in which it is locked against rotation and a position in which it is free to rotate.
