1. An insertable brachytherapy device for adjusting radiation emission direction comprising:
an outer body including a first outer body, a second outer body, and a bent part for connecting the first outer body and the second outer body such that the outer body is bent;
an inner body including a first inner body, a second inner body, and an inner connection part comprising a rotation power mechanism, the inner connection part connecting the first inner body and the second inner body;
wherein the first inner body is positioned inside the first outer body and includes an accommodation space in which a radiation source is accommodated, the second inner body is positioned inside the second outer body and includes a guide space enabling the radiation source to pass therethrough, the second inner body being capable of rotating, and the inner connection part is positioned in correspondence to the bent part of the outer body, the inner connection part having a connection space communicating with the guide space and the accommodation space such that the radiation source is allowed to pass through the connection space and the guide space, and
wherein the first inner body is separated from the first outer body and rotated by the rotation of the second inner body.
