Abstract
Zur operativen Behandlung von Krampfadern mit Hilfe eines Lasers wird eine Lichtleitersonde vorgeschlagen, deren Lichtleiter am lichtaustrittsseitigen Ende aufgerauht und von einer lichtdurchlässigen Kappe aus Teflon umgeben ist, die in Richtung ihrer Längsachse verlaufende Nute aufweist. Einer Zerstörung des Lichtleiters durch thermische Überbelastung am lichtaustrittsseitigen Ende ist mittels eines dort zwischen der Kappe und dem Lichtleiter angeordneten Luftspaltes und der Anordnung einer metallischen Masse vorgebeugt.For the surgical treatment of varicose veins with the aid of a laser, a light guide probe is proposed, the light guide of which is roughened at the end on the light exit side and is surrounded by a transparent cap made of Teflon, which has grooves running in the direction of its longitudinal axis. Destruction of the light guide due to thermal overload at the end on the light exit side is prevented by means of an air gap arranged there between the cap and the light guide and the arrangement of a metallic mass.
Claims (4)
daß auf das abgemantelte Ende des Lichtleiters im Bereich der lichtdurchlässigen Kappe ein metallischer
Ring aufgeschoben ist. 55According to the invention, this object is achieved by
that on the stripped end of the light guide in the area of the translucent cap a metallic
Ring is pushed open. 55
versehen an beliebige medizinische Lasergeräte handelsüblicher Ausbildung anschließbar, wobei wegen ihres hohen wirksamen Infrarotgehaltes der Laserstrahlung beispielsweise Lasergeräte des Neodyn-YAG- 60
Typs eine bevorzugte Stelle einnehmen.Such a probe has known couplings
provided can be connected to any medical laser devices of commercially available design, with Neodyn-YAG-60, for example, because of their high effective infrared content of the laser radiation
Type occupy a preferred position.
sind in den Unteransprüchen beschrieben.Further advantageous embodiments of the invention
are described in the subclaims.
