Title (EN) MAGNETIC SWITCHING ELEMENT FOR CONTROLLING A SURGICAL DEVICE
(FR) ELEMENT DE COMMUTATION MAGNETIQUE POUR COMMANDER UN DISPOSITIF CHIRURGICAL
Abstract:
(EN) An apparatus for controlling a surgical device includes a housing (105) and a magnetic switching element (400) mounted on the housing (105). The magnetic switching element (400) includes a magnet (405), a magnetic sensor (500) configured to produce a control signal for controlling the surgical device, and an actuator (410) mounted on the housing (105) for movement between a first position in which a magnetic field of the magnet is decoupled from the magnetic sensor (500) and a second position in which the magnetic field is coupled to the magnetic sensor (500) so as to change a value of the control signal produced by the magnetic sensor (500). The magnetic switching element (400) may also include magnetically soft material positioned so that movement of the actuator causes relative movement between the magnet and the magnetically soft material.
(FR) L'invention concerne un appareil pour commander un dispositif chirurgical, comportant un boîtier (105) sur lequel est monté un élément de commutation magnétique (400). Ce dernier comprend un aimant (405), un capteur magnétique (500) configuré pour produire un signal de commande en vue de la commande du dispositif chirurgical, et un actionneur (410) monté sur le boîtier (105) pour permettre le déplacement entre une première position dans laquelle un champ magnétique de l'aimant est découplé du capteur magnétique (500) et une deuxième position dans laquelle le champ magnétique est couplé au capteur magnétique (500) de manière à faire varier une valeur du signal de commande produit par le capteur magnétique (500). L'élément de commutation magnétique (400) peut également comporter un matériau magnétiquement doux positionné de sorte que le mouvement de l'actionneur provoque un mouvement relatif entre l'aimant et le matériau magnétiquement doux.
