Title: (DE) CHIRURGISCHES HANDSTÜCK MIT KOMPAKTER KUPPLUNG
(EN) SURGICAL HANDPIECE WITH COMPACT CLUTCH
(FR) PIECE A MAIN CHIRURGICALE A EMBRAYAGE COMPACT
Abstract: front page image
(EN) A surgical handpiece (20) with a rotating spindle (42) for receiving the coupling head (54) of a surgical attachment (320) or a cutting accessory (48). A gear train (36) has plural drive heads (86, 92) that simultaneously rotate at different speeds. A clutch assembly (44) has pins (184) that move along the length of the spindle. The clutch assembly sets the position of the pins so they will engage one of the drive heads . The spindle rotates with the drive head with which the clutch pins are engaged.
(FR) L'invention concerne une pièce à main chirurgicale (20) comprenant un arbre rotatif (42) destiné à recevoir la tête d'accouplement (54) d'un accessoire chirurgical (320) ou d'un accessoire de coupe (48). Un train d'engrenages (36) comprend plusieurs têtes d'entraînement (86, 92) qui tournent simultanément à des vitesses différentes. Un ensemble embrayage (44) comprend des broches (184) qui se déplacent sur la longueur de l'arbre. L'ensemble embrayage règle la position des broches de manière qu'elles coopèrent avec l'une des têtes d'entraînement. L'arbre tourne avec la tête d'entraînement avec laquelle les broches d'embrayage coopèrent.
