Medizinische Vorrichtung für lokalisierte TherapieMedical device for localized therapy
Die Erfindung bezieht sich auf eine Vorrichtung für die medizinische Therapie. Mehr insbesondere bezieht sich die Erfindung auf die Therapie von bösartigen Tumoren.The invention relates to a device for medical therapy. More specifically relates to that Invention on the therapy of malignant tumors.
In der Vergangenheit hat sich ergeben, daß es wünschenswert ist, Tumore mittels radioaktiver Isotopen durch Bestrahlung zu behandeln. Gleicherweise hat man herausgefunden, daß sich Tumore auch zufriedenstellend durch Diathermie behandeln lassen.In the past it has been found to be desirable is to treat tumors using radioactive isotopes through irradiation. It has also been found that Tumors can also be treated satisfactorily by diathermy.
Mit der erfindungsgemäßen Vorrichtung kann eine lokalisierte Diathermie und gleichzeitig eine lokalisierte Bestrahlungstherapie vorgenommen werden. Die Vorrichtung umfaßt einen Ring- bzw. Schlauchkörper, welcher als elektrischer Leiter ausgebildet und elektrisch an einen geeigneten Leiter für die Versorgung mit elektrischem Strom ange-With the device according to the invention, a localized Diathermy and localized radiation therapy at the same time be made. The device comprises a ring or hose body, which as an electrical Conductor formed and electrically connected to a suitable conductor for the supply of electrical power.
schlossen .lsi:. Der elektrisch leitende Ring- bzw. Schlauchkörper hat eine Vielzahl von Öffnungen, die durch diesen in Radialrichtung verlaufen. Eine elektrische Isolierung befindet sich neben diesem Ring- bzw. Schlauchkörper und liegt teilweise so an diesem an, daß ein nichtisolierter Abschnitt de;; Ring- bzw. Schlauchkörpers freiliegt. Innerhalb dieses freiliegenden Bereiches befindet sich zumindest eine radioaktiven Isotope für die Bestrahlungsbehandlung des lokalisierten Bereiches, welcher ebenso eine Diathermiebehandlung erfährt.closed .lsi :. The electrically conductive ring or hose body has a plurality of openings extending through it in the radial direction. Electrical insulation is located next to this ring or hose body and is partially on this so that a non-insulated Section de ;; Ring or hose body is exposed. Within this exposed area there is at least a radioactive isotope for the radiation treatment of the localized area, which is also a diathermy treatment learns.
Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung der in den Zeichnungen rein schematisch dargestellten Ausführungsbeispiele. Es zeigt:Further details, features and advantages of the invention emerge from the following description of the FIGS Drawings purely schematically illustrated embodiments. It shows:
Fig. 1 eine Seitenansicht der Vorrichtung gemäß der Erfindung, Fig. 1 is a side view of the device according to the invention,
Fig. 2 eine vergrößerte rJ eil-Querschnittsansicht ungefähr entlang der Linie 2-2 der Fig. 1 undFig. 2 is an enlarged r J express cross-sectional view taken approximately along line 2-2 of Fig. 1 and
Fig. 3 eine Querschnittsansicht ungefähr entlang der Linie 3-3 in Fig. 2.3 is a cross-sectional view taken approximately along line 3-3 in FIG. 2.
In Fig. 1 ist eine mit dem Bezugszeichen 1 versehene Vorrichtung zur lokalisierten Diathermie und gleichzeitig zur lokalisierten Bestrahlungstherapiebehandlung dargestellt. Die Vorrichtung 1 umfaßt einen ring- bzw. schlauchförmigen Körper 3, welcher aus einem elektrischen Leiter besteht. Dieser Ringkörper hat eine Vielzahl von Öffnungen, die von diesem radial nach außen verlaufen. Ein elektrischer Isolator 5 befindet sich neben dem Ringkörper und liegt an diesem an. Bei einer bevorzugten Ausführungsform 5 verläuft der elektrisch leitende Ringkörper 3 über einenIn Fig. 1 is provided with the reference numeral 1 device for localized diathermy and at the same time for localized radiation therapy treatment. The device 1 comprises an annular or tubular Body 3, which consists of an electrical conductor. This ring body has a multitude of openings, which run radially outward from this. An electrical insulator 5 is located next to the ring body and is due to this. In a preferred embodiment 5, the electrically conductive ring body 3 extends over a
nichtisolierten Abschniit. Der elektrisch leitende Ringkörper 3 kann über den uaisolierten Abschnitt desselben mittels des Anschlusses an einen elektrischen Leiter 17 und einen elektrischen Kontakt. 15 eine Diathermiebehandlung vorsehen, wobei über den elektrischen Leiter 17 und den elektrischen Kontakt 15 ein Hochfrequenzstrom zugeführt wird. Der elektrische Letter 17 ist durch einen elektrischen Isolator 19 isoliert.non-isolated section. The electrically conductive ring body 3 can be connected to an electrical conductor 17 via the insulated section thereof and an electrical contact. 15 provide a diathermy treatment, using the electrical conductor 17 and the electrical contact 15 is supplied with a high-frequency current will. The electrical letter 17 is through an electrical Isolator 19 isolated.
Bei einer bevorzugten Ausführungsform sind innerhalb einer Hülse 9 im unisolierten Abschnitt des Ringkörpers 3 eine Vielzahl von radioaktiven Isotopen 7 vorgesehen. Vorzugsweise wird die Vorrichtung neben einem Tumor angeordnet, welcher dadurch behandelt wird, daß ein Abschnitt reduzierten Durchmessers der Hülse 9 in eine hohle Stange geführt wird, welche dann in den Körper des Patienten für die vorzunehmende Therapie eingeführt wird, bis sich.der unisolierte Abschnitt des Ringkörpers 3 neben dem Tumor befindet. Ein Anschlag 13 verhindert ein Durchziehen der Vorrichtung durch den zu behandelnden Bereich. Vorzugsweise besteht der Ringkörper 3 aus einem Material, welches den elektrischen Strom leitet und ist daher als Geflecht aus rostfreiem Stahl ausgebildet. Die Hülse 9 besteht aus einem Nylonrohr und der elektrische Isolator 5 aus PoIyäthylen. In a preferred embodiment, within one Sleeve 9 in the uninsulated section of the ring body 3 a plurality of radioactive isotopes 7 is provided. Preferably For example, the device is placed next to a tumor which is being treated by reducing a section Diameter of the sleeve 9 is guided into a hollow rod, which then into the body of the patient for the Therapy to be undertaken is introduced until sich.der uninsulated section of the ring body 3 next to the tumor is located. A stop 13 prevents the device from being pulled through the area to be treated. Preferably the ring body 3 consists of a material which conducts the electric current and is therefore as a braid made of stainless steel. The sleeve 9 consists of a nylon tube and the electrical insulator 5 consists of polyethylene.
