Fixing device and tool for surgical holding systems

摘要

The fastening device has a holding element (1) mechanically connected to an attachment element (2). The holding element includes a joint pan (8) and a ball joint (3) that are connected, to form a ball-and-socket joint whose movement is locked by a clamping element. An eccentric hoop (12) of the clamping element is clamped during rotation of the ball joint with respect to the joint pan. The eccentric hoop is clamped with respect to the joint pan and ball joint, to uniquely define position of three contact points of ball-and-socket joint, for locking ball-and-socket joint. An independent claim is included for tool for fixing, locking and loosening of fastening device.
