Intracavitary radiotherapy apparatus and use method thereof

An intracavitary radiotherapy apparatus, which is used for carrying radioactive particles or particle strips, comprising:

• a body that is formed by winding metal wires and is a wire mesh having a hollow cavity penetrating through same in the forward and backward directions;
• and
• a radioactive particle groove that is formed in the outer surface of the body, is a cylindrical wire mesh having a hollow cavity penetrating through same in the forward and backward directions, and is used for accommodating the radioactive particles or particle strips, wherein
• the radioactive particle groove comprises a plurality of groove bodies arranged in parallel, and spacing between every two adjacent groove bodies is less than the length of the radioactive particles or the particle strips;
• and
• the radioactive particle groove and the body are made of the same material by winding metal wires, or are made of biodegradable material by means of one-step injection molding.
