[0028] Among them, the driving member is arranged in the treatment box 102, one end of the screw rod 104 is connected to the driving member, and the other end of the screw rod 104 is rotatably connected to the treatment box 102, the sleeve 105 is sleeved on the outside of the screw rod 104, and is threadedly matched with the screw rod 104, the U-shaped frame 106 is fixedly connected to the sleeve 105 and is located below the sleeve 105, the radiotherapy device 107 is arranged on the inner wall of the U-shaped frame 106, the U-shaped frame 106 has two sliding grooves 114, and the two extrusion rings 108 are respectively arranged in the corresponding sliding grooves 114, and the two ends of each of the resisting springs 109 are respectively fixedly connected to the U-shaped frame 106 and the corresponding extrusion ring 108. When treating the patient, make the patient lie on the mobile frame 103, and then move the mobile frame 103 into the treatment box 102, based on The radiotherapy device 107 is moved according to the treatment part of the patient. By starting the driving member, the driving member drives the screw rod 104 to rotate in the treatment box 102. Since the sleeve 105 is threadedly matched with the screw rod 104, the sleeve 105 will move laterally on the screw rod 104, and the U-shaped frame 106 will move along with it. At the same time, the extrusion ring 108 will slide in the sliding groove 114 of the U-shaped frame 106, and the supporting spring 109 will also expand and contract. The elastic force of the supporting spring 109 will push the extrusion ring 108 to fit tightly against the treatment part of the patient. After the U-shaped frame 106 is moved to the specified position, the radiotherapy device 107 is located directly above the treatment part of the patient. Then the radiotherapy device 107 is started to treat the patient, thereby protecting other healthy parts of the patient from radiation damage and improving safety.

[0029] Secondly, the support platform 101 has two interlocking grooves 113, and the multiple interlocking blocks 110 are fixedly connected to the U-shaped frame 106 and are respectively located in the interlocking grooves 113. When the U-shaped frame 106 moves, the interlocking blocks 110 under the U-shaped frame 106 will move in the interlocking grooves 113 on the support platform 101, which can increase the stability of the movement of the U-shaped frame 106 and also make the U-shaped frame 106 tightly connected to the support platform 101 to avoid the existence of gaps.

[0030] At the same time, the support plate 111 is fixedly connected to the treatment box 102 and is located on the inner wall of the treatment box 102. The motor 112 is fixedly connected to the support plate 111 and is located above the support plate 111. The output end of the motor 112 is fixedly connected to the screw rod 104. The support plate 111 fixedly supports the motor 112 on the inner wall of the treatment box 102, and the motor 112 controls the screw rod 104 to rotate in the treatment box 102.

[0031] When treating a patient, the patient lies on the mobile frame 103, and then the mobile frame 103 is moved into the treatment box 102. The radiotherapy device 107 is moved according to the treatment site of the patient, and the motor 112 on the support plate 111 is started. The motor 112 drives the screw rod 104 to rotate in the treatment box 102. Since the sleeve 105 is threadedly matched with the screw rod 104, the sleeve 105 will move laterally on the screw rod 104, and the U-shaped frame 106 will move with it, and the interlocking block 110 under the U-shaped frame 106 will also move in the treatment box 102. The support platform 101 moves in the fitting groove 113, and at the same time, the extrusion ring 108 slides in the sliding groove 114 of the U-shaped frame 106, and the supporting spring 109 also expands and contracts. The elastic force of the supporting spring 109 pushes the extrusion ring 108 to fit tightly against the patient's treatment part. After the U-shaped frame 106 is moved to the specified position, the radiotherapy device 107 is located directly above the patient's treatment part, and then the radiotherapy device 107 is started to treat the patient, thereby protecting other healthy parts of the patient from radiation damage and improving safety.

When the patient is treated, the patient lies on the movable frame 103 with the patient's head located between the two jackets 204. The telescopic rod 202 and the limit spring 203 will be compressed. At the same time, the resilience of the limit spring 203 will drive the jacket 204 to fix the patient's head on the movable frame 103 to the upper limit, thereby preventing the patient from moving on the support platform 101.

[0037] The shifting block 205 is fixedly connected to the jacket 204 and is located on the outer side wall of the jacket 204 . The shifting block 205 is used to pull the jacket 204 to move, thereby facilitating the patient's head to enter between the two jackets 204 .

[0038] The squeeze sponge 206 is fixedly connected to the jacket 204 and is located on the inner wall of the jacket 204. The squeeze sponge 206 can increase the comfort of the jacket 204 in contact with the patient's head.

[0039] When the patient is treated, the patient lies on the movable frame 103, and the shift block 205 is used to drive the sleeve 204 to move. The patient's head is located between the two sleeves 204, and the telescopic rod 202 and the limit spring 203 are compressed. At the same time, the rebound force of the limit spring 203 drives the sleeve 204 to fix the patient's head on the movable frame 103 to prevent the patient's head from moving on the support platform 101 and reduce tension. By arranging the squeezing sponge 206 on the inner wall of the sleeve 204, the squeezing sponge 206 can increase the comfort of the contact between the sleeve 204 and the patient's body.
