The multi-channel converted X-ray source applicator of this embodiment is used in radiation therapy for X-ray source radiotherapy equipment, such as Xoft therapy machines. As shown in fig. 7, the X-ray source radiotherapy apparatus is provided with a radiation source catheter 50, and the X-ray source is located at the tip (front end) of the radiation source catheter 50. The source catheter 50 is provided with a marker 51, and the length of the marker 51 to the end of the source catheter may be referred to as the marker length L0. After the guide post 10, the channel switching post 20 and the connector rod 30 are assembled, the distance L1 from the tail end of the connector rod to the front end of the guide hole (as shown in fig. 2) is equal to the mark length L0 of the radioactive source catheter, so that the mark 51 can indicate the position of the front end of the radioactive source catheter in the applicator, and when the mark 51 reaches the tail end of the connector rod, the end of the radioactive source catheter can be indicated to reach the front end 11a of the guide hole 11, and the radioactive source catheter can not extend into the applicator continuously.

Embodiment two:
as shown in fig. 13 to 18, a multi-channel conversion X-ray source applicator, this embodiment is a modification of the first embodiment.
The multi-channel converted X-ray source applicator of the first embodiment is applicable to gynecological radiation treatment including the vagina. The present embodiment is modified on the basis of the first embodiment to make it an applicator more suitable for cervical radiotherapy.
In this embodiment, the front end of the guide post 10 is provided with a uterine cavity tube 15, and the uterine cavity tube 15 is slightly curved in order to be suitable for cervical radiotherapy. The guide post 10 is provided with three guide holes, wherein the guide holes comprise a uterine cavity guide hole 11c, and a uterine cavity tube 15 is connected with the uterine cavity guide hole 11c of the uterine cavity tube. The front end of the uterine cavity guide hole 11c is provided at the center of the guide post. The uterine cavity tube 15 is screwed with the uterine cavity guide hole 11c.
The guide post 10 is also provided with two other guide holes 11e arranged at both sides of the uterine cavity guide hole 11 c. Thus, the uterine cavity guide hole 11c and the guide holes 11e on both sides constitute a typical Gong Gengshi source structure. The three guide holes are all guide holes of a curved structure, and the rear end circumferences of the three guide holes are equally distributed to correspond to the conversion channels 21 of the channel conversion column 20.
The channel switching post 20 is provided with a joint guide rod 26, the joint rod 30 is provided with a joint guide sleeve 33, the joint guide rod 26 is in rotary fit and sliding fit with the joint guide sleeve 33, and the channel switching post 20 can rotate relative to the joint rod 30 and also can slide relative to the joint rod along the axial direction.
The joint guide rod 26 is provided with a circle of second axial groove 27, the joint guide sleeve is provided with a second positioning screw 34 and a third positioning screw 35, and the ends of the second positioning screw 34 and the third positioning screw 35 can be respectively embedded into the second axial groove 27.
When the connector rod 30 moves to the front end relative to the channel switching post 20, as shown in fig. 17, the second positioning screw 34 is inserted into the second axial groove 27, and the distance L3 from the tail end of the connector rod to the front end of the uterine cavity tube is equal to the identification length of the radioactive source catheter, so that the radioactive source can reach the end of the uterine cavity tube.
When the joint lever 30 moves to the rear end with respect to the channel switching post 20, as shown in fig. 18, the third positioning screw 35 is inserted into the second axial groove 27, and the distance L4 from the tail end of the joint lever to the front ends of the guide holes 11e on both sides is equal to the identification length of the radioactive source catheter, so that the travel of the radioactive source can be controlled not to exceed the front ends of the guide holes 11e on both sides.
In this embodiment, turning the channel switching post 20 allows the radiation channel to be switched between the uterine cavity guide hole 11c and the guide holes 11e on both sides. In cervical radiotherapy, the radioactive source needs to move between different strokes and positions, and the position of the joint rod 30 can be adjusted by moving back and forth, so that the stroke position of the radioactive source can be controlled, and the requirements of different stroke positions of the radioactive source can be met.
Since the inner diameter of the joint guide sleeve 33 is larger than the conversion channel 21 of the channel conversion column when the joint lever moves backward as shown in fig. 18, the rear end of the conversion channel 21 is provided with a bevel 28 in order to make the radiation source catheter 50 smoothly enter the conversion channel 21.
