Abstract

Pour résoudre les problèmes de la technique associée, l'invention concerne un support pour un instrument médical, selon une forme de réalisation de la présente invention, comprenant : un corps de support ; une première liaison couplée au corps de support ; une deuxième liaison couplée à une portion d'extrémité de la première liaison ; une première poulie montée en rotation sur une portion de couplage entre le corps de support et la première liaison ; une deuxième poulie montée en rotation sur la portion de couplage entre la première liaison et la deuxième liaison ; et une courroie de synchronisation formée pour entourer la première et la deuxième poulie de façon que la première et la deuxième poulie tournent ensemble. Les poulies de la courroie sont montées sur la première liaison, et la courroie de synchronisation relie les poulies de la courroie, en simplifiant ainsi la structure du support. En outre, du fait du couplage des poulies et de la courroie de synchronisation, le support présente une plage d'entraînement plus large qu'un support de la technique associée.
