The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of radioactive seed loader that helps to overcome card source phenomenon is provided.
The purpose of this utility model is achieved in that a kind of radioactive seed loader, comprise the housing 2 that is provided with magazine 1, pressing pole 3, spring 4 and top cover 5, described pressing pole 3 bottoms are thick portion 3.1, top is thin portion 3.2, be boss structure, can move up and down along magazine 1, have the through hole 6 that thin portion 3.2 cross sections with pressing pole 3 are complementary in the middle of the described top cover 5, the periphery of top cover 5 is provided with and the housing 2 tops bayonet socket 7 of clamping mutually, described spring 4 is placed in the thin portion 3.2 of pressing pole 3, spring upper end 4.1 is connected with top cover inner surface 5.1, spring lower end 4.2 places the thick upper surface 3.1.1 of portion of pressing pole 3, the square-section of described magazine cross section for holding radioactive seed 8, described housing 2 is before magazine 1 bottom, respectively have a through hole 9 that the center is symmetrical on the symmetric pair of sidewalls 1.1 in back, the diameter of the diameter of through hole 9 and every radioactive seed 8 is complementary, and described housing 2 bottoms have a cleanout fluid hand-hole 10.
Described housing 2 is transparent or semitransparent medical plastic manufacturing.
The beneficial effects of the utility model are: owing to use technical scheme described in the utility model, particularly housing bottom has a cleanout fluid hand-hole, overcome the card source problem effectively, make beneficial effects such as the radioactive particle implant surgery is safer, easy, efficient.
