Spulen zur Darstellung oberflächennahen Gewebes bei einer MR-gestützten Tumortherapie sind als Interventionsspulen oder als Oberflächenspulen für Hochfrequenzmagnetfelder bei Kernspinuntersuchungen bekannt. Zumeist bestehen die Oberflächenspulen aus ein oder zwei kapazitiv gekoppelten ringförmigen Schleifenteilen mit einem Innen- und Außenleiter. Das vom einen Schleifenteil abgewandte Ende mündet in ein Griffstück mit den entsprechenden Abstimmungs- und Anpassungskondensatoren und Spannungszuführung. Die Spulenoberfläche muss dazu neben speziellen Eigenschaften hinsichtlich der MR-Kompatibilität auch hohe Anforderungen an die Robustheit, Desinfizierbarkeit und Biokompatibilität erfüllen. Coils for imaging near-surface tissue in MR-assisted tumor therapy are known as interventional coils or as surface coils for radiofrequency magnetic fields in MRI examinations. In most cases, the surface coils consist of one or two capacitively coupled annular loop parts with an inner and outer conductor. The remote from a loop part ends in a handle with the appropriate tuning and matching capacitors and power supply. In addition to special properties with regard to MR compatibility, the coil surface must also meet high requirements for robustness, disinfectability and biocompatibility.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, einen ringförmigen Gegenstand einfach mit einem Mantel aus einem Kunststoff zu versehen.The indicated in
Diese Aufgabe wird gelöst durch eine Vorrichtung zum Einschweißen eines ringförmigen Gegenstandes in einen Mantel aus einem Kunststoff
- a) mit einem Grundkörper für den zwischen zwei Folienkörpern aus dem Kunststoff platzierten ringförmigen Gegenstand und
- b) mit zwei Elektroden für einen Bereich außer- und innerhalb des ringförmigen Gegenstandes, wobei jeweils eine Elektrode – einen Kern aus einem Metall sowie – mindestens einen um den Kern gewickelten band- oder drahtförmigen Körper mit sowohl einer Ader aus einem Metall als auch einer isolierenden Schicht aus einem elektrisch nichtleitenden Mantel aufweist, – der Kern ein Ring ist und – der band- oder drahtförmige Körper zwei Anschlüsse für eine Verbindung mit einer elektrischen Energiequelle besitzt, und
- c) mit einer elektrischen Energiequelle in Verbindung mit den Elektroden.
- a) with a base body for the placed between two film bodies of the plastic annular object and
- b) having two electrodes for a region outside and inside the annular article, wherein one electrode each - a core of a metal and - at least one wound around the core band or wire-shaped body with both a strand of a metal and an insulating Comprising a layer of an electrically non-conductive jacket, - the core is a ring and - the band or wire-shaped body has two terminals for connection to an electrical energy source, and
- c) with an electrical energy source in connection with the electrodes.
Die Vorrichtungen zum Einschweißen eines ringförmigen Gegenstandes in einen Mantel aus einem Kunststoff zeichnen sich insbesondere dadurch aus, dass der Gegenstand einfach mit dem Mantel versehen werden kann. The devices for welding an annular object into a sheath made of a plastic are characterized in particular by the fact that the object can be easily provided with the sheath.
Dazu weist die Vorrichtung einen Grundkörper für den zwischen zwei Folienkörpern aus dem Kunststoff platzierten ringförmigen Gegenstand und zwei Elektroden für Bereiche außer- und innerhalb des ringförmigen Gegenstandes auf. For this purpose, the device has a base body for the annular object placed between the two film bodies made of the plastic and two electrodes for areas outside and inside the annular object.
Jede der Elektroden besitzt einen Kern aus einem Metall, vorzugsweise aus Stahl. Weiterhin weist diese mindestens einen um den Kern gewickelten band- oder drahtförmigen Körper, vorzugsweise aus Kupfer, mit sowohl einer Ader aus einem Metall als auch einem elektrisch nichtleitenden Mantel auf. Der Kern oder der band- oder drahtförmige Körper ist dabei vorteilhafterweise ein Ring. Entweder der Kern oder der band- oder drahtförmige Körper besitzen zwei Anschlüsse für eine Verbindung mit einer elektrischen Energiequelle. Ein weiterer Bestandteil der Vorrichtung ist die elektrische Energiequelle in Verbindung mit den Elektroden.Each of the electrodes has a core of a metal, preferably of steel. Furthermore, this has at least one wound around the core band or wire-shaped body, preferably made of copper, with both a wire of a metal and an electrically non-conductive jacket. The core or the band or wire-shaped body is advantageously a ring. Either the core or the ribbon or wire body has two terminals for connection to an electrical energy source. Another component of the device is the electrical energy source in connection with the electrodes.
Die Vorrichtung eignet sich insbesondere für Oberflächenspulen, die eine ringförmige Gestalt besitzen können, als ringförmige Gegenstände, die direkt auf die Haut aufzulegen sind. Das sind beispielsweise Interventionsspulen oder Oberflächenspulen für Hochfrequenzmagnetfelder, die zur Darstellung oberflächennahen Gewebes bei einer MR-gestützten Tumortherapie dienen. Die Spulenoberfläche muss dazu neben speziellen Eigenschaften hinsichtlich der MR-Kompatibilität auch hohe Anforderungen an die Robustheit, Desinfizierbarkeit und Biokompatibilität erfüllen. Eine dauerhafte Umhüllung der Spule ist damit nicht möglich. Derartige Anforderungen können nur Einwegumhüllungen erfüllen.The device is particularly suitable for surface coils, which may have an annular shape, as annular objects which are to be placed directly on the skin. These are, for example, interventional coils or surface coils for high-frequency magnetic fields, which are used to display near-surface tissue in MR-assisted tumor therapy. In addition to special properties with regard to MR compatibility, the coil surface must also meet high requirements for robustness, disinfectability and biocompatibility. A permanent wrapping of the coil is thus not possible. Such requirements can only meet disposable wrappings.
Die Vorrichtung zeichnet sich vorteilhafterweise dadurch aus, dass die ringförmig gestaltete Spule einfach mit einer Einwegumhüllung versehbar ist. Dazu weist die Vorrichtung zwei ringförmige Elektroden als Heizdrähte auf, die dem Schweißen der Folienkörper dienen. Der ringförmige Gegenstand bzw. die Oberflächenspule für Hochfrequenzmagnetfelder befindet sich dabei zwischen sowohl den Folienkörpern als auch den Elektroden oder den nacheinander zugeführten Elektroden. Die Elektroden zeichnen sich dabei dadurch aus, dass diese Elektroden Ringelektroden ohne Unterbrechung des Ringes sind. Das wird durch den band- oder drahtförmigen Körper auf dem Kern erreicht. Der Kern oder der band- oder drahtförmige Körper ist durch die Verbindung mit der elektrischen Spannungsquelle als elektrischer Widerstand die eigentliche Heizung. Der ringförmige Gegenstand oder die Oberflächenspule für Hochfrequenzmagnetfelder kann vollständig im Folienkörper angeordnet und fixiert sein. The device is advantageously distinguished by the fact that the annular coil can easily be provided with a disposable sheath. For this purpose, the device has two annular electrodes as heating wires, which serve to weld the film body. The annular object or the surface coil for high-frequency magnetic fields is located between both the film bodies and the electrodes or the successively supplied electrodes. The electrodes are characterized in that these electrodes are ring electrodes without interruption of the ring. This is achieved by the band or wire-shaped body on the core. The core or the band or wire-shaped body is the actual heating by the connection with the electrical voltage source as an electrical resistance. The annular object or the surface coil for high-frequency magnetic fields can be arranged and fixed completely in the film body.
Zur Handhabbarkeit der Elektroden können diese einzeln oder zusammen an eine sparate Schaltvorrichtung gekoppelt sein.For the handling of the electrodes, these can be coupled individually or together to a sparate switching device.

Der Heizdraht besteht dazu günstigerweise aus einer hochwarmfesten Kupferlegierung. Der band- oder drahtförmige Körper stellt dabei einen Wärmeüberträger für die mit dem Kern erzeugte thermische Energie dar. The core of the electrode is a heating wire according to a development of the invention and as such an electrical resistance in a circuit with the power source. The necessary distance of the terminals is bridged at the electrode by means of the band or wire-shaped body on the core. The heating wire is conveniently made of a high temperature copper alloy. The ribbon or wire-shaped body is a heat exchanger for the thermal energy generated by the core.
