Title
(EN) TORQUE INDICATOR RATCHET WRENCH FOR DENTISTRY
(FR) CLE A CLIQUET AVEC INDICATEUR DE COUPLE DE SERRAGE POUR DENTISTERIE
Abstract
(EN)
Ratchet wrench and a torque indicator combined concentrically in a single housing. The ratchet wrench is useful for driving a fastener used in dentistry. In operation, the handle of the wrench can be rotated in one direction to impart torque on the fastener. When the handle is rotated in the opposite direction, no torque is applied to the fastener as the handle is returned to a position where it is easy for the clinician to again rotate the handle to apply additional torque to the fastener. To provide an indication of torque, a rotor body is supported coaxially within the driver member. Torque indicator marks on the rotor body and the driver member indicate angular displacement of the driver member around the common axis relative to the rotor body when a tool held in the rotor body is restrained from turning under load.
(FR)
Clé à cliquet et indicateur de couple de serrage réunis concentriquement sous un même boîtier. La clé à cliquet convient pour le serrage d'une fixation utilisée en dentisterie. Pendant l'utilisation, la poignée de la clé peut être tournée dans un sens de manière à transmettre un couple de serrage à la fixation. Lorsque la poignée est tournée dans le sens opposé, aucun couple de serrage n'est transmis, ce qui permet de tourner la poignée pour serrer de nouveau la fixation. Un élément de rotor, maintenu coaxialement dans l'élément d'entraînement, renseigne sur le couple de serrage appliqué. Des valeurs de couple portées sur le corps du rotor et sur l'élément d'entraînement indiquent le déplacement angulaire de l'élément d'entraînement autour de l'axe commun par rapport au corps de rotor, lorsque l'outil maintenu dans le corps de rotor est empêché de tourner sous charge.
