A surgical drill guide assembly (100) for demountable attachment to a slotted bone plate is provided. The drill guide assembly (100) includes one or more alignment drill tubes (134; 136) that are remotely aligned with corresponding fastener holes in the bone plate, and an expandable bushing (206) that is configured and dimensioned to engage a slot in the bone plate. A variable angle block (202) permits angulation of the alignment drill tubes (134; 136) about a central axis of the surgical drill guide assembly (100). The alignment drill tubes (134; 136) are releasably lockable at a surgeon-selected angle.
L'invention porte sur un guide de perceuse (100) se fixant réversiblement à un os fendu, et comportant un ou plusieurs tubes d'alignement de la perceuse (134; 136) qu'on aligne à distance sur des trous de fixation correspondant percés dans la plaque osseuse, et une douille dilatable (206) configurée et dimensionnée pour s'engager dans une fente de la plaque osseuse. Un bloc de réglage d'angle (202) permet de modifier l'angle des tubes d'alignement de la perceuse (134; 136) autour de l'axe central du guide (100), lesdits tubes (134; 136) étant réversiblement verrouillables selon l'angle choisi par le chirurgien.
