Title
(EN) BONE PREPARATION DEVICE
(FR) DISPOSITIF DE RÉPARATION OSSEUSE
Abstract
(EN)
An assembly for preparing bone stock includes a shell (52) comprising a base (54) having a support surface (56), and a lid (58). The base and lid have a void space (60) therebetween. A carriage (62) is disposed at least partially within the void space, and moveable across the support surface. The carriage comprises a wall (64), at least a portion (65) of which is resiliently deformable. The wall cooperates with the base to define a preparation chamber (66), and a removal element (68) configured to remove soft tissue from the bone stock is disposed at least partially therein. The resilient portion of the wall is configured to deform when bone stock is positioned between the removal element and the wall. The carriage is configured to receive power from a drive train to actuate movement of the carriage across the support surface, and the removal element is also configured to receive power from the drive train.
(FR)
L'invention concerne un ensemble pour préparer une matière osseuse comprenant une coque (52) comprenant une base (54) présentant une surface support (56) et un couvercle (58). La base et le couvercle présentent un espace vide (60) entre eux. Un chariot (62) est disposé au moins partiellement à l'intérieur de l'espace vide et peut être déplacé à travers la surface de support. Le chariot comprend une paroi (64) dont au moins une partie (65) est élastiquement déformable. La paroi coopère avec la base pour définir une chambre de préparation (66) et un élément de retrait (68) conçu pour retirer du tissu mou de la matière osseuse est disposé au moins partiellement en son sein. La partie élastique de la paroi est conçue pour se déformer lorsque la matière osseuse est positionnée entre l'élément de retrait et la paroi. Le chariot est conçu pour recevoir de l'énergie provenant d'un train d'entraînement pour actionner le mouvement du chariot à travers la surface de support et l'élément de retrait est également conçu pour recevoir de l'énergie provenant du train d'entraînement.
