CA 2001214

An intraosseous needle assembly includes an intraosseous needle having a threaded shaft with an passageway extending substantially therethrough, a solid and pointed tip at one end thereof, the tip having a pair of concave indentations creating cutting edges. At the opposite end of the shaft, or hub, the needle is adapted to couple with an appropriate gripping device. A handle is provided in the shape of a ball knob and is adapted to telescopically and grippingly receive the hub of the needle. The hub and handle are both equipped with mutually engaging torque-transmitting surfaces.

Vis de fixation interne comportant une vis à tige filetée traversée par un passage longitudinal; l'extrémité de la tige comporte une pointe solide et effilée, du fait de deux échancrures concaves formant des bords tranchants. € l'autre extrémité de la tige, ou collet, la vis est conçue pour couplage à un dispositif de préhension. Une poignée sous forme de bouton sphérique est conçue pour saisir le collet de la vis. Le collet de la vis et la poignée comportent tous deux des surfaces permettant la transmission du couple.
