Title
(EN) A DRIVER
(FR) DISPOSITIF D'ENTRAINEMENT
Abstract
(EN)
A driver (100) for use in orthopaedic surgery or the like having a generally elongate housing (102) adapted for single-handed gripping operation. The driver includes engagement means (104) associated with the housing for releasably engaging the proximal end of a longitudinally extending driven member and includes drive means, such as a flexible drive spindle (108), for rotatably driving the engagement means. The driver further includes shield means (110) that are supportingly connected with an end of the housing so as to extend co-axially with and fully circumscribe the driven member. The distal end of the shield means (110) terminates in an end portion (114) adapted to be placed against the surface into which the member is driven. The driver also includes means to permit relative movement in an axial direction between the engagement means (104) and the end portion (114) for advancement into and retraction from the surface so that, in use, single-handedly, the driven member (106) is always fully shielded and supported. In the preferred form of the invention the relative movement between the engagement means (104) and end portion (114) is achieved by means of a longitudinally retracting shield (110). In other embodiments the shield is fixed and the engagement means are advanced internally within the housing.
(FR)
Dispositif d'entraînement (100) destiné à la chirurgie orthopédique ou assimilée, comportant un boîtier de forme générale allongée (102) conçu pour être tenu et actionné d'une seule main. Le dispositif comporte un système d'accouplement (104), associé au boîtier de façon à s'accoupler de manière libérable avec l'extrémité proximale d'un élément entraîné s'étendant longitudinalement, et un système d'entraînement, tel qu'un arbre d'entraînement flexible (108), permettant de faire tourner le système d'accouplement. Le dispositif de pilotage comporte également un système de protection (110) relié à une extrémité du boîtier et soutenu par lui, qui s'étend coaxialement par rapport à l'élément entraîné et l'entoure totalement. L'extrémité distale du système de protection (110) se termine par une partie terminale (114) conçue pour être placée contre la surface dans laquelle est entraîné l'élément entraîné. Celui-ci comporte également un système permettant le déplacement relatif, en direction axiale, du système d'accouplement (104) et de la partie terminale (114), de façon que ceux-ci puissent avancer à l'intérieur de la surface et en être retirés, et que, en cours d'utilisation à l'aide d'une seule main, l'élément entraîné (106) soit toujours totalement protégé et soutenu. Dans la forme préférée de l'invention, le déplacement relatif du système d'accouplement (104) et de la partie terminale (114) est réalisé au moyen d'une protection à rétraction longitudinale (110). Dans d'autres modes de réalisation, la protection est fixe et le système d'accouplement avance à l'intérieur du boîtier.
