Abstract
Description
Die Erfindung betrifft eine Nachlade-Strahlentherapievor richtung bestehend aus einem Strahlenschutzbehälter mit einem festen und einem beweglichen Teil, der sowohl die Rolle eines sicheren Strahlenschutzes als auch eines Wei chensystems erfüllt.The invention relates to reloading radiation therapy direction consisting of a radiation protection container with a fixed and a moving part that both the Role of a safe radiation protection as well as a Wei chensystems fulfilled.
Nachlade-Strahlentherapiegeräte, welche mittels einer Weiche eine einzige Strahlenquelle innerhalb der Hohlsonde von Punkt zu Punkt fahren und nach Verstellen der Rohrkanalweiche in die nächste Hohlsonde eingefahren werden müssen, haben den Nach teil, daß durch diese zwangsläufig vorgegebene Vorgehenswei se sich eine sehr lange Behandlungsdauer ergibt. Andererseits ist ein Gerät mit einer großen Anzahl unabhängig voneinander ausfahrbarer Quellen sehr kostspielig.Reloading radiation therapy devices, which by means of a switch a single radiation source within the hollow probe from point drive to the point and after adjusting the pipe duct switch in the next hollow probe must be retracted, have the night partly that by this inevitably predetermined procedure there is a very long duration of treatment. On the other hand, a device with a large number is independent extendable sources very expensive.
Der Erfindung liegt die Aufgabe zugrunde, ein Nachlade-Strah lentherapiegerät zu schaffen, bei dem eine Anzahl von Quellen unabhängig voneinander ausfahrbar sind, wobei gleichzeitig die Möglichkeit geschaffen ist, mehrere Quellen gleichzeitig aus zufahren und dann auch gleichzeitig nach dem Rückfahren in die Ausgangsstellung und Verstellen des Weichensystems in die nächsten Hohlsonden wieder auszufahren.The invention has for its object a reload beam Lentherapy device using a number of sources are extendable independently of each other, with the Possibility is created from multiple sources simultaneously drive and then at the same time after returning to the Starting position and adjustment of the switch system in the extend the next hollow probe again.
Als technische Lösung wird hierfür ein Nachlade-Strahlen therapiegerät der genannten Art mit folgenden Merkmalen vorgeschlagen:Reloading blasting is the technical solution Therapy device of the type mentioned with the following features suggested:
-
a) Der Strahlenschutzbehälter ist gleichzeitig Bestand
teil eines Weichensystems und besteht aus zwei Haupt
teilen.
- 1. Ein zylinderförmiger in Ruhelage verbleibender Teil, welcher mit 1-3 geraden Ladekanälen ausge rüstet ist, die fest an 1-3 Behandlungskanälen angeschlossen werden können.
- 2. Ein zweiter zylinderförmiger Teil mit einem konzen trischen zylinderförmigen Hohlraum, in den genau der in Ruhelage verbleibende erste Teil eingeschoben werden kann.
- Dieser mit dem Hohlraum versehene Teil ist um die gemeinsame Achse drehbar und mit gekrümmten Lade kanälen ausgerüstet, die wahlweise mit einer größeren Anzahl von Behandlungskanälen nacheinander fluchtend fest verbunden werden können. Das Drehen des äußeren Zylinderteils wird durch ein Kugellager-System, welches beide Teile verbindet, ermöglicht.
- 1. A cylindrical part in the rest position, which is equipped with 1-3 straight charging channels, which can be firmly connected to 1-3 treatment channels.
- 2. A second cylindrical part with a concentric cylindrical cavity into which exactly the first part remaining in the rest position can be inserted.
- This part provided with the cavity is rotatable about the common axis and equipped with curved loading channels, which can optionally be firmly connected in succession with a larger number of treatment channels. The rotation of the outer cylinder part is made possible by a ball bearing system that connects both parts.
- b) Die Quellen werden mittels eines Kabels aus den Ladekanälen in die Behandlungskanäle ausgefahren. Die Schrittmotore, welche den Kabelantrieb der entsprechenden Quellen bewirken sind fest mit dem drehbaren äußeren Teil des Strahlen schutzbehälters verbunden. Die Schrittmotore, welche die Quellenausfuhr aus den Ladekanälen des in Ruhelage ver bleibenden Teils bewirken, sind fest mit dem Gerätegehäuse verbunden, d.h. sie sind also immer in Ruhelage.b) The sources are removed from the charging channels using a cable extended into the treatment channels. The stepper motors, which cause the cable drive of the corresponding sources are fixed to the rotatable outer part of the blasting protective container connected. The stepper motors that the Source export from the loading channels of the idle ver permanent part are fixed to the device housing connected, i.e. so they are always at rest.
- c) Die Drehbewegung des äußeren zylinderförmigen Teils wird über ein Zahnradgetriebe mit einem Schrittmotor erzielt.c) The rotational movement of the outer cylindrical part is achieved via a gear transmission with a stepper motor.
- d) Ein optoelektronisches Abtastsystem hat die Aufgabe, nur dann den Start eines Ladekanal-Schrittmotors freizugeben, wenn ein Behandlungskanal richtig angeschlossen ist.d) An optoelectronic scanning system only has the task then release the start of a charging channel stepper motor, if a treatment channel is connected correctly.
