Dispositif d'accouplement pour la connexion amovible d'une pièce à main médicale, en particulier dentaire, dotée d'une unité d'entraînement ou d'un tuyau flexible d'alimentation
A coupling device for releasably connecting a handpiece to another component. One of a first coupling element and a second coupling element, is designed as a coupling cavity, into which a coupling protrusion on the other coupling element can be inserted. A positioning element is disposed on the first coupling element or the second coupling element and can be inserted into a first recess on the other coupling element to position the two coupling elements in a defined angular position about their common axis. A light source disposed in a second recess on the first or second coupling element can be coupled to an optical fiber on the other coupling element. A transfer element disposed on the first or second coupling element and inserted into a third recess on the other coupling element is configured to transfer data, signals and/or energy between the first and second coupling elements.
