Laser treatment unit especially for medical or dental purposes
First Claim
1. A dental laser treatment unit comprising:
- a control unit;
a supply device;
a first releasable connection connecting the supply device with the control unit;
a laser treatment instrument having a front end and an outlet at the front end for a laser beam;
a second releasable connection connecting the laser treatment instrument with the supply device;
at least first and second medium supply lines which issue from the control unit, extend through the first releasable connection, along the supply device, and through the second releasable connection to the laser treatment instrument, with the first medium line supplying a laser beam, and the second medium line supplying a fluid;
wherein at least one of the first and second releasable connections comprises a cylindrical plug-in coupling, which engages and disengages elastically, having a cylindrical coupling peg and a cylindrical coupling bushing which receives the cylindrical coupling peg, with a cylindrical gap being defined between the cylindrical coupling peg and the cylindrical coupling bushing, and wherein the cylindrical coupling bushing is sealed by sealing means relative to the cylindrical coupling peg, with the first medium line for the laser beam extending coaxially through the at least one plug-in coupling, and the second medium line extending to an annular groove provided between the inner wall of the cylindrical coupling bushing and the outer wall of the cylindrical coupling peg, such that the cylindrical coupling peg can rotate by 360° and
more relative to the cylindrical coupling bushing without interrupting the second medium line, and wherein the second medium line continues from said annular groove to the front end of the treatment instrument.

Abstract
A dental laser treatment unit, especially for medical or dental purposes having a control unit and a supply device, connected with the control unit by a releasable connection, for a laser treatment instrument. Two medium lines are provided, which lines issue from the control unit, extend through the releasable connection and along the supply device to the laser treatment instrument and with the laser treatment instrument being connectable with the supply device likewise by a releasable connection,
the releasable connection between the control unit and the supply device and/or between the supply device and the laser treatment instrument is formed by a plug-in coupling, which automatically engages and disengages elastically, having a cylindrical coupling peg and a cylindrical coupling bushing which receives the peg, with the medium line for the laser beam extending coaxially through the plug-in coupling and the further medium line passing through the cylindrical separating line between the coupling peg and the coupling bushing in a sealed manner, and continuing in the coupling peg and in the coupling bushing, and with there being provided next to the mouth opening at the separating line an annular groove in the inner wall of the coupling bushing or preferably in the outer wall of the coupling peg.
