Logical centralized positioning chamber II, and the round raised face of level of the positioning pin is anchored on the spheroidal end of the top cylinder.
The diameter of the horizontal round raised face is more than I or described perforation centralized positioning chamber II of the perforation centralized positioning chamber
Diameter.
The positioning pin is metal round rod, the diameter of the metal round rod and the I or described perforation of perforation centralized positioning chamber
The diameter of centralized positioning chamber II is identical.
The diameter of the top cylinder and the common cylinder is highly 25mm.
Spheroidal end vertical range of the cecum for applying source chamber apart from the top cylinder is 12.5mm.
It is parallel and equal with the perforation centralized positioning chamber I to be opened by radii fixus around the perforation centralized positioning chamber I
What 6 of even distribution were used to place supply radiator duct applies source chamber.
Around the perforation centralized positioning chamber II with opened by radii fixus it is parallel with the perforation centralized positioning chamber II and
Equally distributed 6 are applied source chamber for placing the perforation of supply radiator duct.
The perforation centralized positioning chamber I matches with the perforation centralized positioning chamber II.
The source chamber of applying applies source chamber and matches with the perforation.
The utility model has the following advantages compared with prior art：
1, the utility model includes 1 top to be linked together in the positioning pin of horizontal round raised face by one end end face
Hold cylinder and 3 ~ 4 common cylinders, dress applies source module manufacture after the cylinder of this segmentation is not only advantageous to, and is easy to
Supply radiator duct is passed through from place supply radiator duct chamber, while being also beneficial to operating personnel and being selected to make according to rectal neoplasm position or vagina length
With.
2, when carrying out rectum or vagina afterloading radiotherapy, the utility model can be selected according to rectal neoplasm position or vagina length
The cylinder using segmentation is selected, is conducive to treatment and fixes, greatly reduce that afterloading radiotherapy applies that source module shift in position brings controls
Risk is treated, to overcome the disadvantage present in existing afterloading radiotherapy applicating device.
3, the utility model is simple in structure, easy to use.
