A spinal aspiration apparatus 10 is described that includes a needle 1 1 that has a shape suitable for the location of and penetration through a pedicle pathway of a vertebra 1. The distal end portion of the spinal aspiration apparatus 10 includes a plurality of apertures that are in fluid communication with a lumen 24 of needle 1 1. The size and angular orientation of the apertures are constructed using the principles of fluid mechanics to create separate and distinct harvest volumes of bone marrow 4 within a body 2 of vertebra 1. A proximal end portion 14 of needle 1 1 includes an external interface 17 that is adapted to provide a fluid tight coupling with an external source of reduced pressure. A handle 16 is connected to proximal end portion 14 that aids in the manipulation of needle 1 1.
L'invention porte sur un appareil pour aspirations spinales 10 comportant une aiguille 1 1 permettant de localiser, et de traverser la voie du pédicule d'une vertèbre 1. L'extrémité distale de l'appareil 10 comprend plusieurs ouvertures communiquant avec la lumière 24 de l'aiguille 1 1. La taille et l'orientation angulaire des ouvertures sont calculées selon les principes de la mécanique des fluides pour créer des volumes de recueil séparés et distincts de moelle 4 dans le corps 2 de la vertèbre 1. L'extrémité proximale 14 de l'aiguille 1 1 comprend une interface externe 17 permettant un couplage étanche avec une source externe sous faible pression. Une poignée 16 reliée à l'extrémité proximale 14 aide à manipuler l'aiguille 1 1.
