Description
Technical Field
The invention relates to the technical field of radiotherapy, in particular to a source box connecting device, a source box and a source tank.
Background
The gamma knife is a non-invasive radiotherapy device for treating cancer, which selectively determines the pathological tissue in the cranium or in vivo as a target point according to the principle of solid geometry orientation, and uses gamma rays generated by cobalt-60 to carry out one-time large-dose focusing irradiation so as to generate focal necrosis or function change to achieve the purpose of treating diseases. The method has the advantages of accurate target point, high dosage rate, short treatment time, high tumor control rate and the like, so that the method is widely applied at home and abroad in recent years. However, since cobalt-60 (cobalt source) as a radiation source gradually decays with time, the dose is reduced by half every 5.27 years, so that the periodic source changing work is required to ensure the requirement of the dose rate during treatment.
Under the condition that a plurality of cobalt sources are arranged on a source box, at present, source guiding is realized through a source guiding tool. When the source guiding is carried out, firstly, a source guiding tool and a shielding door are in butt joint with a source tank (new source box is stored), then the shielding door is opened, a plug of the source tank is led into the source guiding tool through a pull rod of the source guiding tool, then the shielding door is closed, the source guiding tool is separated from the shielding door and is moved out of the plug, then, the source guiding tool is in butt joint with the shielding door again, then the shielding door is opened, the new source box (new source) in the source tank is led into the source guiding tool through the pull rod, then the shielding door is closed, the source guiding tool and the whole shielding door are separated from the source tank, finally, the source guiding tool and the whole shielding door are in butt joint with radiotherapy equipment, and the shielding door is opened, so that the source box is led into the radiotherapy equipment. The source guiding process realizes that the new source in the source tank is guided into the radiotherapy equipment, and the old source in the radiotherapy equipment can be guided into the empty source tank in the same way. However, the above process requires that the plug of the source tank is first removed from the source tank and then the source cartridge in the source tank is guided out, which is time consuming and inefficient. Accordingly, there is a need to provide a new solution to ameliorate one or more of the problems presented in the above solutions.
It is noted that this section is intended to provide a background or context for the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
