Title (EN) ROTATION PRESERVING QUICK CONNECT DEVICE
(FR) DISPOSITIF DE CONNEXION RAPIDE ANTI-ROTATION
Abstract: front page image
(EN)The present invention is directed to a tool holder for use with a surgical robot. The tool holder includes, a rotor fixed to the tool shaft, and a stator fixed to the robot. The stator includes a magnet, and a bearing surface. The rotor includes a magnetic material that attaches securely to the tool shaft, such that the tool is in the center of the rotor. The rotor rotates against the bearing surface on the stator, allowing the tool to rotate about its axis. To exchange tools, the user exerts force on the tool until the holding force of the magnet is exceeded and the tool detaches from the stator. A new tool is introduced into the vicinity of the stator such that the magnet attracts the magnetic material on the rotor. The present invention eliminates the need to slide the tool through a shaft of the tool holder.
(FR)La présente invention a trait à un porte-outil destiné à être utilisé avec un robot chirurgical. Ce porte-outil comprend un rotor fixé au manche de l'outil, et un stator fixé au robot. Le stator comprend un aimant et une surface d'appui. Le rotor comporte un matériau magnétique qui se solidarise au manche de l'outil, de sorte que l'outil se trouve au centre dudit rotor. Le rotor tourne contre la surface d'appui du stator, faisant tourner l'outil sur son axe. Pour changer d'outil, l'utilisateur exerce une force sur l'outil jusqu'à dépasser la force de maintien de l'aimant, et l'outil se détache du stator. Un nouvel outil est introduit dans le voisinage du stator de manière à ce que l'aimant attire le matériau magnétique du rotor. Grâce à la présente invention, il est inutile de faire glisser l'outil sur une tige du porte-outil.
