Abstract
A permanently implantable positioning and fixing system for positioning and fixing of an implantable device relative to a human body, including a plate member constructed to affix to the human body a ball-and-socket joint having a socket attached to the fixing member and a ball positionably mounted in the socket, a clamp mechanism cooperating with the ball-and-socket joint for selectively fixing the ball relative to the socket, a guide rail which is fixed to the ball of the ball-and-socket joint, the guide rail including outer guide surfaces, a threaded spindle having an outer thread, the threaded spindle being mounted to rotate relative to the guide rail and to prevent axial movement of the threaded spindle, a carriage with a feed nut having an inner thread that is engaged by the outer thread of the threaded spindle in a manner that the carriage is freely positionable along the guide rail by turning the threaded spindle, the carriage including inner guide surfaces that slidingly engage the outer guide surfaces of the guide rail, and a receiver attached to the carriage for receiving an implantable device which is to be positioned and fixed in the human body.
