Title (EN) ARTHROSCOPIC DEVICES AND METHODS
(FR) DISPOSITIFS ET MÉTHODES D'ARTHROSCOPIE
Abstract:
(EN) A resecting probe includes a shaft assembly having an outer sleeve and an inner sleeve. The outer sleeve has an axial bore and an outer window in a distal side thereof, and the inner sleeve has an axial extraction channel and inner window in a distal side thereof. The inner sleeve is rotationally disposed in the axial bore of the outer sleeve to allow the inner sleeve window to be rotated in and out of alignment with the outer sleeve window, and the shaft assembly forms a flow aperture in a distal portion when the inner cutting window and the outer cutting window are out of alignment. An electrode is carried on the inner sleeve, and a motor drive is coupled to rotate the inner sleeve relative to the outer sleeve. A controller is coupled to the motor drive and controls rotation of the inner sleeve and can stop rotation of the inner sleeve in a stop position where the outer and inner windows are out of alignment, providing the flow aperture to allow cooling of fluid in a working space and cooling of the probe handpiece during use.
(FR) L'invention concerne une sonde de résection comprenant un ensemble tige ayant un manchon externe et un manchon interne. Le manchon externe a un alésage axial et une fenêtre externe dans un côté distal de celui-ci, et le manchon interne a un canal d'extraction axial et une fenêtre interne dans un côté distal de celui-ci. Le manchon interne est disposé de façon rotative dans l'alésage axial du manchon externe pour permettre à la fenêtre de manchon interne d'être tournée dans et hors de l'alignement avec la fenêtre de manchon externe, et l'ensemble tige forme une ouverture d'écoulement dans une partie distale lorsque la fenêtre de coupe interne et la fenêtre de coupe externe sont hors alignement. Une électrode est portée sur le manchon interne, et un entraînement de moteur est couplé pour faire tourner le manchon interne par rapport au manchon externe. Un dispositif de commande est couplé à l'entraînement de moteur et commande la rotation du manchon interne et peut arrêter la rotation du manchon interne dans une position d'arrêt où les fenêtres externe et interne sont hors alignement, fournissant l'ouverture d'écoulement pour permettre le refroidissement d'un fluide dans un espace de travail et le refroidissement de la pièce à main de sonde pendant l'utilisation.
