Abstract
Description
Die Erfindung betrifft eine Kapsel für die Strahlentherapie im Magen-Darmtrakt sowie der Speiseröhre.The invention relates to a capsule for radiation therapy in the gastrointestinal tract and esophagus.
Aus der
In der
Aus der WO 02/10 22 24 A2 ist eine Video-Kapsel bekannt für die Diagnose im Magen-Darmtrakt.From WO 02/10 22 24 A2 is one Video capsule known for the diagnosis in the gastrointestinal tract.
Der Erfindung liegt die Aufgabe zugrunde, eine Kapsel anzugeben, welche eine wirkungsvolle, schonende Strahlentherapie zur Behandlung von Erkrankungen, beispielsweise von Tumoren im Magen-Darmtrakt sowie der Speiseröhre ermöglicht.The invention has for its object a Specify capsule, which is an effective, gentle radiation therapy for the treatment of diseases, for example tumors in the gastrointestinal tract as well as the esophagus allows.
Diese Aufgabe wird durch eine Kapsel mit den im Anspruch 1 aufgeführten Merkmalen gelöst; vorteilhafte Ausgestaltungen und Weiterbildungen sind in den Unteransprüchen angegeben.This task is done through a capsule with those listed in claim 1 Features solved; advantageous Refinements and developments are specified in the subclaims.
Der Grundgedanke der Erfindung besteht darin, in der oral zu verabreichenden Kapsel, die aus einem Gehäuse mit Verschlussstopfen aus einem gegen sämtliche Verdauungssekrete des menschlichen Organismus resistenten Material, z. B. Kunststoff besteht, mindestens einen hermetisch verschlossenen Behälter aus Kunststoff, Glas oder Metall mit mindestens einer Strahlenquelle, beispielsweise 60Kobalt unterzubringen. Die Kapsel verfügt weiterhin über mindestens einen kugelförmigen Körper aus magnetischem Material, damit sie an der erkrankten Stelle im Magen-Darmtrakt durch ein von außen an den Körper angelegtes Magnetfeld solange festgehalten werden kann, bis die gewünschte Dauer der Strahlentherapie erreicht ist.The basic idea of the invention consists in the orally administered capsule, which consists of a housing with sealing plugs made of a material resistant to all digestive secretions of the human organism, e.g. B. plastic consists of accommodating at least one hermetically sealed container made of plastic, glass or metal with at least one radiation source, for example 60 cobalt. The capsule also has at least one spherical body made of magnetic material so that it can be held on the diseased area in the gastrointestinal tract by a magnetic field applied to the body from the outside until the desired duration of the radiation therapy is reached.
Bei der Halbtiefentherapie und Tiefentherapie werden heute vorwiegend Telekobaltgeräte, auch „Kobaltkanonen" genannt, eingesetzt. Die für die Behandlung benötigten Strahlen müssen mehrere Zentimeter gesundes Gewebe durchdringen, bis sie an der erkrankten Stelle, z. B. dem Tumor im Magen-Darmtrakt ankommen. Die Strahlenquelle besteht dabei aus einem mit 60Kobaltkügelchen vollgepackten Zylinder mit einem Durchmesser von 1–2 cm und einer Länge von 2–4 cm. (Durch Neutronenbeschuss wird in einem Kernreaktor künstlich so Kobalt erzeugt).Half-depth therapy and deep therapy today mainly use telecobalt devices, also called "cobalt cannons". The rays required for the treatment have to penetrate several centimeters of healthy tissue until they arrive at the diseased area, for example the tumor in the gastrointestinal tract. the radiation source consists of a packed with 60 beads cobalt cylinder with a diameter of 1-2 cm and a length of 2-4 cm. (by neutron bombardment is so generated artificially cobalt in a nuclear reactor).
(Radiologie, Kauffmann-Moser-Sauer)(Radiology, Kauffmann-Moser-Sauer)
Die Erfindung beinhaltet die Möglichkeit, die Strahlenquelle nicht von außen durch das gesunde Gewebe hindurch, sondern direkt so nah wie möglich an die erkrankte Stelle im Magen-Darmtrakt bzw. in der Speiseröhre heranzuführen. Dadurch ist eine wesentlich geringere Dosis für die Behandlung nötig. Die Dosis kann so gewählt werden, dass die Strahlung beim Durchwandern der Kapsel durch den Magen-Darmtrakt bis zur erkrankten Stelle für das gesunde Gewebe unschädlich ist, bzw. keine Nebenwirkungen auftreten können. Die Heilerfolge werden nicht durch eine hohe Dosis, sondern durch die Dauer der Behandlung erreicht, also solange wie die Kapsel durch das von außen angelegte Magnetfeld festgehalten wird. Um die Dosis an der erkrankten Stelle dennoch zu erhöhen, besteht die Möglichkeit, mehrere Kapseln in gewissen Zeitabständen oral zu verabreichen, welche dann einzeln durch den Magen-Darmtrakt wandern, aber an der erkrankten Stelle gemeinsam durch das von außen an den Körper angelegte Magnetfeld festgehalten werden. Die Vereinzelung der Kapseln nach erfolgter Behandlung erfolgt durch die stufenweise Zurücknahme der Feldstärke des von außen angelegten Magnetfeldes.The invention includes the possibility the radiation source is not from the outside through the healthy tissue, but directly as close as possible to bring the diseased area in the gastrointestinal tract or in the esophagus. Thereby a much lower dose is required for treatment. The Dose can be chosen be that the radiation when walking through the capsule through the Gastrointestinal tract is harmless to healthy tissue up to the diseased area, or no side effects can occur. The healing success will not achieved by a high dose but by the duration of the treatment, as long as the capsule is held by the external magnetic field becomes. In order to increase the dose at the affected area, there is the possibility, administer several capsules orally at certain intervals, which then migrate individually through the gastrointestinal tract, but on the jointly affected area by the externally applied to the body Magnetic field can be held. Separation of the capsules after Treatment is carried out through the gradual withdrawal the field strength the outside applied magnetic field.
Kapseln mit geringer Dosis können auch als vorbeugende Behandlung oral verabreicht werden, um den Magen-Darmtrakt kontinuierlich zu durchwandern und eventuell in der Entstehung befindliche Entzündungen bereits im Keim zu ersticken.Low dose capsules can also Orally administered as a preventive treatment to the gastrointestinal tract to wander continuously and any inflammation that may be developing to suffocate in the bud.
Die erkrankte Stelle im Magen-Darmtrakt oder
der Speiseröhre
kann durch bekannte bildgebende Verfahren der Medizin, wie z. B.
Röntgentechnik
oder der Ultraschalltechnik ermittelt werden, um so die Position
des von außen
an den Körper
anzulegende Magnetfeld festzulegen. Auch die in der WO 02/10 22
24 A2 offenbarte Video-Kapsel kann hierfür eingesetzt werden. In einem
besonderen Ausführungsbeispiel
könnte
diese Video-Kapsel nach der erfolgten Diagnose gleichzeitig für die anschließende Strahlenbehandlung
verwendet werden. Dabei ist lediglich erforderlich, dass die Video-Kapsel
anstelle des Verschlussstopfens mit dem Gehäuse, das die Strahlenquelle
beinhaltet, hermetisch verbunden wird. (
In einer weiteren Ausführungsform kann das Gehäuse und der Verschlussstopfen aus magnetischem Material, z. B. Eisen mit entsprechenden Oberflächenbeschichtung, z. B. vergolden hergestellt werden.In another embodiment can the housing and the sealing plug made of magnetic material, e.g. B. iron with appropriate surface coating, z. B. gilded.
Die Erfindung wird nachfolgend anhand
von zwei Ausführungsbeispielen
näher erläutert.
