Shell structure of radioactive sealed seed source

The utility model relates to the technical field of radioactive seed sources used for tumor treatment, and discloses a shell structure of a radioactive sealing seed source, which comprises a shell main body, a clamping groove is arranged on the outer edge of the shell main body, and a first convex ring and a second convex ring are fixedly connected on the outer edge of the shell main body. A left inclined groove is formed in the outer edge of the first convex ring, a right inclined groove is formed in the outer edge of the second convex ring, and filter paper is connected to the outer edges of the first convex ring and the second convex ring. According to the shell structure of the radioactive sealed seed source, through the use of the shell main body, a shell of the radioactive sealed seed source cannot move after being implanted into a human body by utilizing a first convex ring and a second convex ring, and meanwhile, the left and right occlusal force is increased by utilizing a left inclined groove and a
