[0033] Please refer to Figures 1-4 The present application provides a technical scheme: a thoraco-abdominal tumor radiotherapy body position fixing device, comprising two mounting plates 2 mounted on both sides of a radiotherapy bed 1, the two mounting plates 2 are respectively in sliding cooperation with both sides of the radiotherapy bed 1 and can slide along the height direction of the radiotherapy bed 1;

[0034] At least one of the mounting plates 2 is internally provided with a containing cavity, and one side of the mounting plate 2 facing the other mounting plate 2 is provided with a through opening in communication with the containing cavity, a rotating rod 3 extending along the length direction of the radiotherapy bed 1 is arranged in the containing cavity, the end of the rotating rod 3 is rotationally connected with the containing cavity, and one end of the rotating rod 3 is connected with a locking member for fixing the rotating rod 3;

[0035] A fixing belt 4 is arranged between the two mounting plates 2, and one end of the fixing belt 4 is connected with the curved surface of the rotating rod 3.

[0036] In the present scheme, the fixing belt 4 can be made of plastic, rubber, cloth and other materials without metal, so that the fixing belt 4 will not affect the normal use of radiotherapy rays;

[0037] The rotating rod 3 is rotationally connected with the accommodating cavity through a torsion spring, wherein the torsion spring, in a natural state, promotes the rotating rod 3 to keep a tendency of winding the fixing belt 4.

[0038] In use, first, the patient lies flat between the fixing belt 4 and the radiotherapy bed 1, and then the two mounting plates 2 are lowered to promote the fixing belt 4 between the two mounting plates 2 to be lowered synchronously, so that the fixing belt 4 contacts the patient, and as the lowering continues, the fixing belt 4 gradually fits the body of the patient, and the operator can release the fixation of the rotating rod 3 through the unlocking member to promote the rotating rod 3 to release part of the fixing belt 4 to adapt to a patient with a larger body size.

[0039] When the patient position is fixed by the thoracic and abdominal tumor radiotherapy body position fixing device, the fixing belt 4 is flexible and gradually fits the body curve of the patient to reduce the movable gap of the patient, and the tension generated when the fixing belt 4 is lowered to a certain extent is used to fix the patient, and the fixing surface of the fixing belt 4 is not a horizontal fixing surface, so as to fit the body curve of different patients and have good flexibility.

[0040] In the embodiment, one end of the rotating rod 3 is provided with a mounting cavity for mounting a locking member, the locking member includes a fixed plate 5 and a movable plate 501 connected with the mounting cavity, the opposite sides of the fixed plate 5 and the movable plate 501 are respectively provided with two groups of tooth portions 502 capable of engaging, one side of the movable plate 501 away from the fixed plate 5 is provided with a handle 6, the handle 6 extends to the outside of the mounting plate 2 through the mounting cavity and the mounting plate 2, the handle 6 and the mounting plate 2 are slidingly connected, and can slide along the length direction of the mounting cavity.

[0041] The movable plate 501 and the handle 6 are movable parts, one end of the handle 6 is located outside the mounting plate 2, so as to facilitate the operator to push and pull the handle 6 to promote the movable plate 501 to approach or move away from the fixed plate 5, and a guide strip 602 extending along the length direction of the handle 6 is further arranged on the side surface of the handle 6 to limit the handle 6 to slide along the length direction of the mounting cavity and cannot rotate.

[0042] In specific use, since the fixed plate 5 is fixedly connected with the rotating rod 3, when the two groups of tooth portions 502 on the opposite sides of the movable plate 501 and the fixed plate 5 engage, the fixed plate 5 and the rotating rod 3 cannot rotate due to the influence of the engagement, so as to keep the length of the fixing belt 4, and promote the fixing belt 4 to contact the body of the patient to generate a certain tension to fix the patient.

[0043] In the embodiment, the locking member includes a spring 601 located in the mounting cavity, the spring 601 is located on the side of the fixed plate 5 away from the movable plate 501, and the two ends of the spring 601 are respectively abutted with the fixed plate 5 and the mounting cavity.

[0044] Wherein, the spring 601 keeps the tendency of pushing the movable plate 501 towards the fixed plate 5 when naturally stretched.

[0045] Specifically, when the operator pulls the handle 6, the fixed plate 5 moves towards the direction of the spring 601, the tooth part 502 between the fixed plate 5 and the movable plate 501 disengages, and the fixed plate 5 extrudes the spring 601, so as to make the spring 601 store elastic energy. When the operator releases the handle 6, the movable plate 501 is pushed towards the direction of the movable plate 501 under the action of the spring 601, so as to reset the movable plate 501, and the tooth part 502 between the two plates engages again.

[0046] In the embodiment, the radiotherapy bed 1 is provided with a sliding plate 7 on each side, the top surface of the sliding plate 7 is provided with a through hole vertically penetrating the sliding plate 7, the mounting plate 2 is in sliding fit with the through hole, one side of the sliding plate 7 is provided with a threaded hole horizontally penetrating the sliding plate 7, and a screw rod 701 is in threaded fit in the threaded hole and can abut against the mounting plate 2 by rotating.

[0047] Specifically, the operator can twist the screw rod 701 to make the screw rod 701 move in the threaded hole towards the mounting plate 2 or away from the mounting plate 2. When the mounting plate 2 is lowered to the fixed belt 4 adheres to the patient's body, the operator twists the screw rod 701 to abut against the mounting plate 2 by the end of the screw rod 701, and then fixes the mounting plate 2 by the friction force of the abutment.

[0048] In the embodiment, the screw rod 701 is provided with a knob 702 vertically connected with the screw rod 701 at the end away from the sliding plate 7, and the sidewall of the knob 702 is provided with anti-slip texture.

[0049] Specifically, when the operator twists the screw rod 701, the operator can better twist the screw rod 701 by holding the knob 702 and the anti-slip texture on the surface of the knob 702.

[0050] In the embodiment, the radiotherapy bed 1 is provided with a sliding groove 8 on each side, and the sliding plate 7 is provided with a sliding block 801 on the side facing the sliding groove 8, and the sliding block 801 is in sliding fit with the sliding groove 8.

[0051] Specifically, the sliding groove 8 and the sliding block 801 cooperate to make the sliding plate 7 and the structure mounted on the sliding plate 7 move along the length of the radiotherapy bed 1, so as to move the fixed belt 4 to fix different parts of the patient, and flexibly fix the chest or abdomen of the patient according to the different parts of the patient.

[0052] In the embodiment, the installation plate 2 is provided with a support plate on the side facing the head of the radiotherapy bed 1, and the lower end of the support plate is rotationally connected with the installation plate 2.
