[0007] However, the above typical and existing technologies still have certain problems when used:

[0008] During radiotherapy, patients usually need to adopt a specific body position to ensure that the radiation can accurately irradiate the tumor site. For example, during radiotherapy for chest tumors, patients need to lie on their backs with their arms raised toward their heads so that the radiation can reach the chest tumor site. In practice, some patients are affected by the pain of the tumor and find it difficult to raise their arms on their own. Therefore, it is necessary to design a radiotherapy bed that can assist in positioning. Utility Model Content

After the rotating disk rotates, the auxiliary positioning arm rotates and swings together with the patient's arm. Since the patient's arm can be turned to a position close to the head, it plays an auxiliary positioning role, so as to facilitate the subsequent radiotherapy of the patient's chest tumor. In addition, in the process of shaking the hand crank to rotate the rotating disk, the linkage belt can drive the linkage shaft to rotate. After the linkage shaft rotates, the rotating disk located on the other side of the treatment bed rotates accordingly. Therefore, in the process of shaking the hand crank on one side, two sets of rotating disks can be rotated at the same time, thereby realizing double-arm positioning;

[0019] 2. The utility model is provided with a movable adjustment mechanism. If the position of the auxiliary positioning mechanism needs to be adjusted, two sets of motors are used to control the rotation of two rotating screws respectively. After the rotating screws are rotated, the adjustment slider connected to the outer thread of the rotating screw moves together with the support arm, thereby adjusting the position of the auxiliary positioning mechanism. In this way, the position of the auxiliary positioning mechanism can be automatically adjusted, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

A linkage belt 208 is sleeved on the outer side of the rotating shaft 206. The lower end of the linkage belt 208 is sleeved on the outer side of the linkage shaft 207. A limiting pad 211 runs through the middle of the linkage shaft 207. The upper end of the limiting pad 211 is fixedly connected to the lower surface of the connecting slider 210. The upper end of the connecting slider 210 is slidably connected to the lower surface of the bed slide rail 209. The upper end of the bed slide rail 209 is fixedly connected to the lower surface of the treatment bed 1. When the hand rocker 205 is shaken to rotate the rotating disk 202, the linkage belt 208 can drive the linkage shaft 207 to rotate. After the linkage shaft 207 rotates, the rotating disk 202 located on the other side of the treatment bed 1 rotates accordingly. Therefore, in the process of shaking the hand rocker 205 on one side, the two sets of rotating disks 202 can be rotated at the same time, thereby realizing the double-arm positioning.

[0029] In specific use, the utility model is a radiotherapy bed that can assist in positioning. Before radiotherapy of a patient's chest tumor, the patient can lie flat on the surface of the treatment bed body 1 and pass both arms through the elastic band 204 and place them on the surface of the auxiliary positioning arm 203. Then, the medical staff can manually shake the hand crank 205 to rotate the rotating disk 202. After the rotating disk 202 rotates, the auxiliary positioning arm 203 rotates and swings together with the patient's arm. Since the patient's arm can be flipped to a position close to the head, it plays a role of auxiliary positioning, so as to facilitate the subsequent radiotherapy of the patient's chest tumor.
