Abstract: The present invention relates to a light guide unit for a laser applicator, wherein the light guide unit has a light guide tip assembly removably insertable into the laser applicator, wherein the light guide tip assembly comprises an optical fiber and a coupling member provided on a proximal end of the optical fiber. When the coupling member is provided on the optical fiber, a proximal end face of the optical fiber needs to be kept clean. It is also desired that the light guide tip assembly can be manufactured easily. It is suggested to provide the coupling member via a casting technique.

Abstract: The invention relates to an optical fibre with a connector piece that has a recess, such as a bore hole, for instance, for accommodating the optical fibre, wherein a fluid channel (18, 14) is provided that begins at the end of the recess and through which a fluid can pass. The invention furthermore relates to an optical fibre with a plug with a gripping piece that has two end openings, wherein the fibre enters into the gripping piece in one end opening and the light of the fibre or the fibre can exit from the gripping piece through the other end opening, wherein the end openings (15, 16) of the gripping piece (2) are interconnected in a way allowing throughflow.

Abstract: Device for severing at least one optical fiber When severing optical fibers (1) with conventional severing devices, after the severing operation the severed fibers (1) are distributed in a disorderly manner on the second fixing element (26), with the result that they can only be removed with difficulty and laboriously. Using a bonding device (20, 21) in the form of a rocker (21) with an adhesive strip (20), the fiber ends are adhesively bonded on during the severing operation, with the result that they remain in an orderly manner on the adhesive strip after the severing operation. The rocker (21) is in this case mounted such that it can pivot between an inserting position and a severing position, in order to facilitate the insertion of the fibers (1).
