Abstract
Description
Die Erfindung betrifft eine Rektalsonde entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a rectal probe according to the preamble of claim 1.
Bei Patienten mit Rektumtumor wird als Referenzmaß klinisch (Palpation) und durch apparative Diagnostik, beispielsweise durch transrektalen Ultraschall üblicherweise die Distanz Anus – caudale Tumorbegrenzung bestimmt. Ist bei fortgeschrittenen Tumoren nach kontinenzerhaltender Operation eine Strahlentherapie indiziert, wird die caudale Begrenzung des Strahlenfeldes 5 cm unterhalb der früheren Tumorgrenze gewählt. Für eine Feldgrenzenwahl ist also die Bestimmung der Distanz Anus – caudale Tumorbegrenzung von entscheidender Bedeutung. Eine geeignete Lösung dieser Aufgabe, angepasst an die individuelle Anatomie des Patienten ist bisher nicht verfügbar.In patients with rectal tumor clinically as a reference measure (Palpation) and by apparatus diagnostics, for example by transrectal ultrasound usually the distance anus - caudale Tumor limitation determined. Is after with advanced tumors continence-preserving surgery indicated radiation therapy, the caudal boundary of the radiation field is 5 cm below the previous tumor boundary selected. For one Field boundary selection is therefore the determination of the anus-caudal distance Tumor limitation is critical. A suitable solution to this Task that is adapted to the patient's individual anatomy not yet available.
Die erfindungsgemäße Rektalsonde ermöglicht es, die Distanz Anus – caudale Tumorgrenze aus einer Röntgenaufnahme eindeutig zu bestimmen und somit für eine Strahlentherapie eine optimale Feldgrenzenwahl durchzuführen. Die Rektalsonde besteht aus einem formhaltigen, nachgiebigen Sondenkörper, in den in definierten Abständen röntgendichte Teile, auf einem Distanzelement aufgereiht, eingebettet sind. Die geometrische Form der Rektalsonde gewährleistet das caudale Umfassen des Sphinkters und verhindert auf diese Weise eine Dislokation des Katheters. Der flexible Sondenkörper passt sich dem individuellen Verlauf des Darmes an. Dem Patienten wird für die Anfertigung einer Röntgenaufnahme die Rektalsonde transrektal eingeführt. Die in der Rektalsonde eingebetteten röntgendichten Teile zeichnen sich in der Röntgenaufnahme deutlich ab. Dadurch kann die Distanz vom Anus zum caudalen Tumorrand im Röntgenbild einfach ausgemessen werden. Mit dieser Information kann für die anschließende Strahlentherapie die Feldbegrenzung eindeutig, an der individuellen Anatomie des Patienten orientiert, durchgeführt werden.The rectal probe according to the invention enables the distance anus - caudale Tumor boundary from an x-ray to be clearly determined and thus a for radiotherapy to carry out optimal field boundary selection. The rectal probe exists from a form-retaining, compliant probe body, in the defined in intervals radiopaque parts, lined up on a spacer element, are embedded. The geometrical Shape of the rectal probe guaranteed the caudal grasping of the sphincter and thus prevents a dislocation of the catheter. The flexible probe body fits the individual course of the intestine. The patient will for the Take an X-ray the rectal probe is inserted transrectally. The one in the rectal probe embedded radiopaque Parts stand out in the X-ray significantly. This allows the distance from the anus to the caudal tumor edge in the x-ray simply be measured. This information can be used for subsequent radiation therapy the field boundary clearly, based on the individual anatomy of the Patient oriented, performed become.
Eine vorteilhafte Ausführung der
Rektalsonde gemäß der Erfindung
ist in den
Der nachgiebige Sondenkörper ist mit einer Shore-Härte von ca. 20 so gewählt, dass er der Form des Rektums folgt, gleichzeitig aber beim Einführen im wesentlichen keinen Druck auf das Rektum ausübt. Die Zone von der kugelförmigen Verdickung bis zum ersten Wulst ist so gewählt, dass dieser Bereich beim Einführen durch den Sphinkters umschlossen und festgehalten wird und die Sonde dadurch definiert positioniert ist. Die Form des ausserhalb des Rektums liegenden Endbereichs der Rektalsonde ermöglicht eine einfache Einführung und Entnahme der Rektalsonde.The compliant probe body is with a shore hardness of about 20 chosen that it follows the shape of the rectum, but at the same time when it is inserted into the exerts essentially no pressure on the rectum. The zone of spherical thickening until the first bead is chosen that this area when inserting is enclosed and held by the sphinkters and the probe thereby positioned. The shape of the outside of the rectum end area of the rectal probe allows easy insertion and Removal of the rectal probe.
