Abstract: A needle shield remover for a wearable injector includes a first portion having a cam member, the first portion having a top surface and a bottom surface positioned opposite to the top surface, and a second portion connected to the first portion. The second portion having a top surface and a bottom surface positioned opposite to the top surface, with the second portion including a device connector configured to secure the second portion of the needle shield remover to the wearable injector. The first portion is moveable relative to the second portion between a first position where the cam member is aligned with the top surface of the second portion and a second position where the cam member protrude from the top surface of the second portion. The cam member is configured to contact a housing of the wearable injector when the first portion is in the second position.

Abstract: A broken intramedullary rod removal tool for extracting the distal end of a broken intramedullary rod from bone in which it is embedded. In a first embodiment the tool has an extraction shaft, an expansion rod disposed and longitudinally movable within the shaft, a strike plate adapter secured to the proximal end of the extraction shaft, a thumb screw secured to the strike plate adapter, and a strike plate secured to the strike plate adapter. The distal end of the extraction shaft is inwardly tapered and has a split-bulb tip, so that the expansion shaft distal end can be flared out by insertion of the distal end of the expansion shaft therein, to expand the tip so that it engages the distal end of the broken intramedullary rod, thus permitting the distal portion of the broken rod to be removed by striking the strike plate to force out the expansion shaft and tip-engaged broken rod end.
