VENTRAL-TELESKOP

摘要

A device for advancing the lower jaw consists of a telescopic sliding device with a telescope origin (1) connected via a ball joint (5) to a first anchorage strip (10) for anchoring to the teeth of a jaw, and a telescope sleeve (2) connected via a second ball joint to a second anchorage strip for anchoring to the teeth of the opposing jaw. The ball joints on the ends of the telescopic sliding device are resistant to tension and compression but can be easily installed and removed. To this end, the ball insert openings in the ball cups (7) of the ball joint are aligned substantially perpendicular to the length of the telescope origin (1) or the telescope sleeve (2) and the ball head (8) of each ball joint (5) can be snapped into the corresponding ball cup (7) by application of a slight force by the operator elastically deforming safety means (11) in the process, and can be removed by the operator, if necessary with the aid of a releasing instrument.
