Radioactive seed protection implanter and performance detection device thereof

The invention relates to a radioactive seed protection implanter and a performance detection device thereof, and relates to the technical field of radioactive seed implantation and detection. Comprising an implanter body, a seed channel allowing radioactive seeds to move is formed in the implanter body in a penetrating mode, an implantation gun head is installed at the head of the implanter body in an inserted connection mode, and a handheld push pipe is installed at the tail of the implanter body in an inserted connection mode. The ejector pin penetrates through the handheld push tube in the length direction of the implanter body and penetrates through a seed channel in the implanter body to extend in the direction of the implantation gun head, the seed bin is movably embedded in the top of the implanter body, and the body fixing part is installed at the end, away from the seed bin, of the implanter body; according to the invention, implantation puncture needles with different specifications can be quickly c
