[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1-5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the radiotherapy support device for cancer patients provided by this utility model; Figure 2 for Figure 1The diagram shows the structure of the radiotherapy support device for cancer patients in the separated state of the front and rear pads. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The diagram shows a structural schematic of one of the clamping mechanisms separated from the rear pad. Figure 5 for Figure 4 The enlarged schematic diagram of part B is shown. The radiotherapy support device for cancer patients includes: a pad, which includes a rear pad 1 and a front pad 2. The rear pad 1 and the front pad 2 are detachable. Four arm support arc plates 3 are installed on the top of the front pad 2. The rear pad 1 can be lengthened as needed, and mature components for restraining the patient's waist and legs, such as restraint belts, can also be installed. A protrusion 11 is integrally formed on the rear pad 1. A notch 201 is provided on the front pad 2. The protrusion 11 is located in the notch 201. Two locking grooves 101 are opened on the outer walls of both sides of the protrusion 11. Square notches 202 are opened on the outer walls of both sides of the front pad 2. Locking rods 4 are slidably installed on the inner walls of the two square notches 202 that are close to each other. The ends of the four locking rods 4 away from the corresponding square notches 202 extend into the corresponding locking grooves 101. The four locking rods 4 restrict the separation of the front pad 2 and the rear pad 1. Each square notch 202 is equipped with a handle 5. Each handle 5 is fixedly connected to one end of the corresponding two locking rods 4 located within the square notch 202. When the arm support arc plate 3 is not required, both hands can be held on the two handles 5 respectively, and then pulled to the sides to disengage the four locking rods 4 from the corresponding locking slots 101. This releases the restriction of the front pad 2, and the front pad 2 can then be removed from the radiotherapy bed. A retaining spring 6 is fitted on the locking rod 4. One end of the retaining spring 6 is fixedly connected to the handle 5, and the other end is fixedly connected to the inner wall of one side of the corresponding square notch 202. The retaining spring 6 provides an initial tension to the handle 5, preventing the locking rod 4 from moving arbitrarily. Two arc-shaped limiting grooves are opened on both outer walls of the front pad 2. Each square notch 202 is connected to the corresponding two arc-shaped limiting grooves, and both ends of the handle 5 are located within the corresponding arc-shaped limiting grooves.

[0022] In this embodiment, in order to increase the mating strength between the front pad 2 and the rear pad 1 and to prevent misalignment at the mating point between them during use, a plurality of reinforcing pins 7 are fixedly installed on the front pad 2, and a plurality of reinforcing slots 102 are provided on the rear pad 1, with the plurality of reinforcing pins 7 located in the corresponding reinforcing slots 102.

[0023] In this embodiment, to prevent significant displacement of the pad during use, four clamping mechanisms are provided on the rear pad 1, arranged in a rectangular array. These clamping mechanisms are used to fix the rear pad 1. Specifically, each clamping mechanism includes a slide bar 8, a clamping plate 9, and an adjusting screw 10. A square groove 103 is provided at the top of the rear pad 1. The slide bar 8 is slidably installed within the square groove 103. Limiting tracks are provided on both inner walls of the square groove 103, and limiting sliders are fixedly installed on both outer walls of the slide bar 8. Two limiting sliders are located within two limiting tracks and are slidably connected to the inner walls of the corresponding limiting tracks. The clamping plate 9 is fixedly installed at the bottom of the slide bar 8, and the adjusting screw 10 passes through and rotates within the groove. On the slide bar 8, the adjusting screw 10 is threadedly connected to the rear pad 1. The inner wall of the square slide groove 103 away from the clamp 9 is provided with an installation groove. A nut is fixedly installed in the installation groove. The adjusting screw 10 passes through the nut and is screwed into the inner wall of the nut. A knob is fixedly installed at the end of the adjusting screw 10 near the clamp 9. When the adjusting screw 10 is rotated counterclockwise by the knob, it can be gradually moved out of the square slide groove 103. The adjusting screw 10 drives the clamp 9 to move, so that the clamp 9 gradually moves away from the rear pad 1. This can increase the distance between the two corresponding clamps 9, so that after the pad is placed on the radiotherapy bed, the clamp 9 can be located on one side of the radiotherapy bed. A rubber pad is fixedly installed on the side of the clamp 9 near the rear pad 1 to prevent the clamp 9 from slipping.

[0024] The working principle of the radiotherapy support device for cancer patients provided by this utility model is as follows:

[0025] In use, first rotate the four adjusting screws 10 counterclockwise. As the adjusting screws 10 rotate counterclockwise, they will gradually move outward from the square slide groove 103. The adjusting screws 10 drive the slide bar 8 to move, increasing the distance between the clamping plate 9 and the rear pad 1. Then, place the pad on the radiotherapy bed. Since the clamping plate 9 has been pre-adjusted, the four clamping plates 9 will be on both sides of the radiotherapy bed. Then, rotate the four adjusting screws 10 clockwise in sequence to release the four clamping plates 9 from the radiotherapy bed. After applying sufficient pre-tightening force to the adjusting screws 10, the four clamping plates 9 can clamp the radiotherapy bed, thus reliably fixing the pad.

[0026] When radiotherapy is performed on the patient's lungs, the patient lies on a mat with both arms extended backward. Each arm is supported by two arm support arc plates 3, so that the patient's upper chest is no longer obstructed, thus allowing for full-body radiotherapy.

[0027] In other application scenarios, such as when performing radiotherapy on the brain of some patients, the arm support arc plate 3 is not required. Furthermore, at some radiation angles, the arm support arc plate 3 can easily obstruct the patient's brain and sometimes hinder the operation of relevant personnel. Therefore, it is necessary to remove the arm support arc plate 3. In this case, the relevant personnel can hold the two handles 5 with both hands and pull them to the sides with a little force. The two handles 5 will drive the corresponding two locking rods 4 to move, causing the locking rods 4 to disengage from the locking slots 101. In this way, the front pad 2 is no longer restricted. Then, while ensuring that the two handles 5 do not reset, drag the front pad 2 forward. After the multiple reinforcing pins 7 on the front pad 2 have completely disengaged from the corresponding reinforcing slots 102, the front pad 2 can be lifted off the radiotherapy table, thereby removing all four arm support arc plates 3 at once.

[0028] Compared with related technologies, the radiotherapy support device for cancer patients provided by this utility model has the following beneficial effects:

[0029] This utility model provides an auxiliary device for radiotherapy of tumor patients. The pad is composed of a rear pad 1 and a front pad 2. Four arm support arc plates 3 are installed on the front pad 2. The rear pad 1 and the front pad 2 can be reliably connected by four locking rods 4, two handles 5, four retaining springs 6 and multiple reinforcing pins 7. When it is necessary to remove the four arm support arc plates 3, the two handles 5 are held by both hands and pulled to the sides to release the restriction between the front pad 2 and the rear pad 1, so that the four arm support arc plates 3 can be removed at one time. It has the advantages of simple operation and time saving. By setting four sets of clamping mechanisms on the rear pad 1, the rear pad 1 can be reliably fixed on the radiotherapy bed to avoid large displacement of the pad, which has the advantages of stable and reliable use.
