US Classification:

606 79, 606 86 R, 606 85

Abstract:

A keel punch impactor comprises a main body having an interior bore. A locking shaft is positioned in the interior bore of the main body, the locking shaft defining a shaft axis. An actuator is in contact with the locking shaft. The actuator is moveable between a first position and a second position. The position of the locking shaft is moved within the interior bore of the main body upon movement of the actuator. In particular, the locking shaft is moved such that the shaft axis is offset when the actuator is moved from the first position to the second position. When the shaft is moved, a head on the shaft is moved into or out of alignment with a boss extending from the main body of the keel punch impactor.

International Classification:

A61B 17/16

Abstract:

Surgical cutting instruments and methods of use are described. The surgical cutting instrument () comprises an instrument body () with a first attachment mechanism () at a distal end. A cutter () has a central core (), a plurality of cutting formations () and a plurality of lobes () extending from the central core. The central core has side walls () which define an entirely open mouth and the side walls include a second attachment mechanism () which can interact with the first attachment mechanism to releasably attach the cutter to the distal end of the instrument body. At least one cutting formation () is provided on an end outer face () of the cutter opposite the entirely open mouth.

International Classification:

A61B 17/16

Abstract:

A surgical instrument assembly includes a metallic hemispherical component and a driver component removably coupled to the hemispherical component. The metallic hemispherical component has a convex outer surface configured to engage a patient's natural acetabulum, a concave inner surface positioned opposite the outer surface and defining a cavity in the hemispherical component, a plurality of cutting teeth extending outwardly from the outer surface, and a plurality of apertures defined in the inner surface. The driver component has a shank and a plurality of ribs secured to, and extending outwardly from, the shank. Each rib has a tab that is received in a corresponding aperture of the hemispherical component to secure the driver component to the hemispherical component.
