Abstract

For the operative treatment of varices with a laser the invention proposes a light guiding probe whose light guide is roughened on the light emergence end and surrounded by a light-permeable Teflon cap having grooves extending in the direction of its longitudinal axis. Destruction of the light guide by thermal overloading on the light emergence end is prevented by an air gap provided there between the cap and the light guide and by the provision of a metallic mass. <IMAGE>

Description

Sonde zum Veröden von KrampfadernProbe for sclerosing varicose veins

Die Erfindung betrifft eine Sonde zum Veröden von Krampfadern mit Hilfe eines Lasergerätes.The invention relates to a probe for sclerosing varicose veins with With the help of a laser device.

Nach dem derzeitigen Stand der medizinischen Praxis erfolgt die Behandlung von Krampfadern mit relativ hohem klinischen Aufwand auf chirurgischem Wege oder mit einem vergleichbar hohen medikamentösen Aufwand unter erheblicher physischer Belastung des Patienten.According to the current state of medical practice, the treatment is carried out of varicose veins with relatively high clinical effort by surgical means or with a comparably high level of drug expenditure with considerable physical effort Stress on the patient.

Der Erfindung liegt die Aufgabe zugrunde, eine Sonde zum Anschluß an bekannte medizinische Lasergeräte zu schaffen, die vom behandelnden Arzt leicht und mit geringer physischer Belastung des Patienten in durch Wärmeeinwirkung zu verödende Blutgefäße einzuführen ist.The invention is based on the object of a probe for connection to create well-known medical laser devices that can easily be used by the attending physician and with little physical stress on the patient due to the effect of heat to introduce sclerosing blood vessels.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Sonde einen ummantelten Lichtleiter aufweist, der am behandlungsseitigen Ende von seiner Ummantelung befreit und aufgerauht ist und dort von einer Kappe aus lichtdurchlässigem Material umgeben ist. Eine derartige Sonde ist mit bekannten Kupplungen versehen an beliebige medizinische Lasergeräte handelsüblicher Ausbildung anschließbar, wobei wegen ihres hohen wirksamen Infrarotgehaltes der Laserstrahlung beispielsweise Lasergeräte des Neodyn-YAG- Typs eine bevorzugte Stelle einnehmen.This object is achieved according to the invention in that the probe has a has sheathed light guide, the end of its sheath on the treatment side is freed and roughened and there by a cap made of translucent material is surrounded. Such a probe is provided with known couplings to any medical laser devices of commercially available training can be connected, because of their high effective infrared content of the laser radiation, for example laser devices of the Neodyn-YAG- Type occupy a preferred position.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Further advantageous refinements of the invention are set out in the subclaims described.

Die Zeichnung zeigt ein nachfolgend beschriebenes Ausführungsbeispiel der Erfindung in einem schematisch vereinfachten Längsschnitt.The drawing shows an exemplary embodiment described below of the invention in a schematically simplified longitudinal section.

In der Figur der Zeichnung ist das applikationsseitige Ende einer Sonde 1 zum Veröden von Krampfadern dargestellt, dase einen ummantelten einaderigen Lichtleiter 2 aufweist, dessen Ummantelung 3 am behandlungsseitigen und aufgerauhten Ende 4 entfernt ist und der dort von einer Kappe 5 aus lichtdurchlässigem Material umgeben ist Wegen der vernachlässigbar geringen Leitungsverluste kann der abgebrochen dargestellte Lichtleiter 2 in jeder praktikablen Länge hergestellt sein.. Er ist an seinem nicht in der Zeichnung enthaltenen Ende mit einer handelsüblichen und dem zur Energieversorgung vorgesehenen Lasergerät entsprechenden Kupplung für den Lichtleiter 2 versehen. Die Kappe 5 ermöglicht die gefahrlose Einbringung der Sonde in eine Ader und gewährleistet in Verbindung mit der rauhen Oberfläche des von seiner Ummantelung befreiten Endes 4 des Lichtleiters 3 einen gleichmäßig an der äußeren Oberfläche 9 der Kappe 5 auftretenden Wärmeübergang, der zu einer partiellen Koagulation des Gewebes an der Behandlungsstelle führt.In the figure of the drawing, the application-side end is a Probe 1 for sclerosing varicose veins shown, which is a sheathed single-veined Has light guide 2, the casing 3 on the treatment side and roughened End 4 is removed and there by a cap 5 made of translucent material Because of the negligibly low line losses, the can be broken off shown light guide 2 be made in any practical length .. He is at its end not included in the drawing with a commercially available and the corresponding coupling for the laser device provided for the energy supply Light guide 2 provided. The cap 5 enables the probe to be introduced safely in a vein and guaranteed in conjunction with the rough surface of its Cladding freed end 4 of the light guide 3 a uniformly on the outer Surface 9 of the cap 5 occurring heat transfer, which leads to a partial coagulation of the tissue at the treatment site.

Ein metallischer Ring 6, der das aufgerauhte Ende 4 des Lichtleiters 2 am Ende der Ummantelung 3 umgibt, vereinfacht eine Verfolgung des Weges der Sonde mit Hilfe eines Röntgenbildes und schützt das freie Faserende des Lichtleiters 2 vor Zerstörung durch unzulässig hohe Erwärmung an seinem Austritt aus der Ummantelung 3, wobei eine Verspiegelung und kugelförmige Krümmung seiner Oberfläche 7 einen günstigen Einfluß auf den Wärmeübergang zur Kappe 5 und den daran anliegenden Gewebe einer nicht dargestellten Ader haben. Zur sicheren Vermeidung einer örtlichen Überhitzung der Kappe 5 umgibt diese das aufgerauhte Ende 4 des Lichtleiters 2 mit eines Luftspalt 8.A metallic ring 6, which is the roughened end 4 of the light guide 2 at the end of the casing 3, simplifies tracking of the path of the probe with the help of an X-ray image and protects the free fiber end of the light guide 2 against destruction due to impermissibly high heating at its exit from the casing 3, with a Mirroring and spherical curvature of its surface 7 a favorable influence on the heat transfer to the cap 5 and the adjacent Have tissue of a vein, not shown. To safely avoid a local Overheating of the cap 5 surrounds it with the roughened end 4 of the light guide 2 an air gap 8.

Die Kappe 5 ist aus einem lichtdurchlässigen Material, vorzugsweise einem infrarotdurchlässigem Material gefertigt, das bei der Durchführung einer Behandlung nicht mit dem Gewebe verklebt Als besonders zweckmäßig hat sich ein unter der Handelsbezeichnung Teflon bekanntes Material erwiesen. An der äußeren Oberfläche 9 der Kappe 5 angebrachte und in Richtung ihrer Längsachse verlaufende Nute 10 vergrößern die wärmeabgebende Oberfläche und verhindern eine Kolbenwirkung bei der Transposition der in ein Blutgefäß eingeführten Sonde Mit der Sonde ist dem Arzt ein preiswertes Gerät in die Hand gegeben, das eine erweiterte Anwendung etwa vorhandener medizinischer Lasergeräte ermöglicht und das bei gefahrloser Handhabung durch den behandelnden Arzt eine weitgehende Entlastung des behandelten Patienten erlaubt.The cap 5 is preferably made of a translucent material made of an infrared-permeable material that when performing a treatment not glued to the fabric. One under the trade name has proven to be particularly useful Teflon proven material. Attached to the outer surface 9 of the cap 5 and grooves 10 extending in the direction of its longitudinal axis enlarge the heat emitting Surface and prevent a piston effect during the transposition into a blood vessel Introduced probe With the probe, the doctor has an inexpensive device at hand given that an expanded application of existing medical laser devices and that with safe handling by the attending physician an extensive Relief of the treated patient allowed.
