[0002] Radiotherapy is a powerful weapon in cancer treatment. Its emergence as a crucial method for treating malignant tumors has directly driven the rapid development of the global radiotherapy equipment industry. Proton and heavy ion therapy is a method that uses proton and heavy ion radiation to treat tumors, demonstrating good therapeutic effects. Proton and heavy ion therapy boasts a high tumor control rate. It can precisely locate and target tumors, concentrating high-energy rays at the tumor site to effectively kill tumor cells. According to various research reports, the tumor control rate of proton and heavy ion therapy can reach over 80%, showing good therapeutic effects for some refractory tumors such as central nervous system tumors, head and neck tumors, lung cancer, and liver cancer. Furthermore, proton and heavy ion therapy can significantly reduce damage to normal tissues.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figure 1-4 A body positioning device for proton and heavy ion therapy patients includes a bed board body 1, a C-shaped plate 2 fixedly connected to the right side of the bed board body 1, a head, neck and shoulder positioning plate 14 horizontally placed on the right side of the front end of the bed board body 1, multiple sets of body membrane positioning holes 21 provided at the rear end of the bed board body 1, a foot fixing frame 22 fixedly connected to the left side of the front end of the bed board body 1, a hip support frame 23 fixedly connected to the middle position of the front end of the bed board body 1, and a positioning component for adjusting the position and fixing the head and shoulders provided at the front end of the C-shaped plate 2.
[0024] Please see Figure 1-4 A positioning fixation device for proton and heavy ion therapy patients also includes a positioning component. The positioning component includes two sets of slides 3, which are horizontally placed at the upper and lower ends of the left front end of the C-shaped plate 2. A slider 4 is welded to the left rear end of the slide 3. A shoulder clamping plate 5 is fixedly connected to the left front end of the slide 3. An adjusting screw 6 is inserted into the right front end of the slide 3. An adjusting handwheel 8 is fixedly connected to the front end of the adjusting screw 6. A stop plate 7 is movably connected to the rear end of the adjusting screw 6. Slide rail grooves 9 are respectively opened at the upper and lower ends of the left front end of the C-shaped plate 2. Multiple sets of internal threaded positioning holes 10 are respectively provided at the upper and lower ends of the right front end of the C-shaped plate 2. External threaded positioning pins 11 are respectively inserted into the upper and lower ends of the right front end of the C-shaped plate 2. A head clamping plate 12 is movably connected to the front end of the external threaded positioning pin 11.
[0025] The slide table 3 is symmetrically distributed about the horizontal center line of the C-shaped plate 2. The internal thread of the slide table 3 is compatible with the external thread of the adjusting screw 6. The external shape and size of the slider 4 are compatible with the internal shape and size of the slide rail groove 9. The slider 4 can slide left and right along the inside of the slide rail groove 9. The external thread of the external rear end of the external thread positioning pin 11 matches the internal thread of the internal thread positioning hole 10. The internal thread positioning holes 10 are arranged at equal intervals to facilitate the adjustment of the head and shoulder positioning position.
[0026] Specifically, such as Figure 1 and Figure 4 As shown, loosen the adjusting handwheel 8. The adjusting handwheel 8 drives the adjusting screw 6 to move, and the adjusting screw 6 pushes the abutment 7 to move backward. The abutment 7 and the C-shaped plate 2 do not contact each other. The slide table 3 and the slider 4 can then move laterally along the slide rail groove 9. After adjusting to the appropriate position, tighten the adjusting handwheel 8 again. According to the patient's head size, the position of the head clamping plate 12 can be adjusted by directly screwing the external thread positioning pin 11 into the corresponding internal thread positioning hole 10.
[0027] Example 2: A first mounting screw hole 13 is provided on the right side of the front end of the head, neck and shoulder positioning plate 14, and two sets of second mounting screw holes 15 are provided on the left side of the front end of the head, neck and shoulder positioning plate 14. Two sets of pressure blocks 16 are movably connected to the upper and lower ends of the front right side of the bed board body 1. The rear end of the pressure block 16 fits against the front end of the head, neck and shoulder positioning plate 14. The first mounting screw hole 13, the second mounting screw hole 15 and the reserved hole inside the bed board body 1 are compatible to facilitate fixing the positioning plate.
[0028] Specifically, such as Figure 2 and Figure 3 As shown, the first mounting screw hole 13 and the second mounting screw hole 15 can be directly driven into the bolt for fixation. The pressure block 16 can be rotated to press directly onto the head, neck and shoulder positioning plate 14. The four sets of pressure blocks 16, together with the three sets of screw holes, can quickly fix the positioning plate.
[0029] Example 3: A reserved groove 19 is provided inside the front right side of the bed board body 1. Velcro loops 20 are glued to the four corners of the rear end of the reserved groove 19. A yoga mat 17 is placed horizontally inside the reserved groove 19. Velcro barbed surfaces 18 are glued to the four corners of the rear end of the yoga mat 17. The positions and dimensions of the Velcro barbed surfaces 18 and the Velcro looped surfaces 20 correspond one-to-one. The front ends of the bed board body 1 and the yoga mat 17 are flush, which makes it easy to replace the soft mat.
[0030] Specifically, such as Figure 1 As shown, the yoga mat 17 can support the back and improve comfort. The yoga mat 17 is connected and fixed by the hook and loop side 18 and the hook and loop side 20 in the reserved groove 19. It can be directly peeled off when it is removed for cleaning and disinfection.
[0031] Working principle: When using this utility model, firstly, the patient lies on the main body 1 of the bed board. The foot fixation frame 22 restricts the position of the feet, the hip support frame 23 supports the hips, and the head, neck and shoulders are placed on the C-shaped plate 2. The shoulder clamping plate 5 is pressed against the patient's shoulder. According to the position of the shoulder, the position of the shoulder clamping plate 5 can be adjusted laterally. Loosen the adjusting handwheel 8. The adjusting handwheel 8 drives the adjusting screw 6 to move. The adjusting screw 6 pushes the abutment plate 7 to move backward. The abutment plate 7 and the C-shaped plate 2 do not contact each other. The slide table 3 and the slider 4 can then move laterally along the slide rail groove 9. After adjusting to the appropriate position, tighten the adjusting handwheel 8 again. According to the size of the patient's head, the position of the head clamping plate 12 can be adjusted by directly screwing the external thread positioning pin 11 into the corresponding internal thread positioning hole 10. The head, neck, and shoulder positioning plate 14 is placed directly in the groove on the side of the bed board body 1. Bolts can be directly driven into the first mounting screw hole 13 and the second mounting screw hole 15 for fixation. Rotating the pressure block 16 allows it to be pressed directly onto the head, neck, and shoulder positioning plate 14. Four sets of pressure blocks 16, in conjunction with three sets of screw holes, allow for quick and easy fixation of the positioning plate. For the patient's back, the yoga mat 17 provides support and enhances comfort. The yoga mat 17 is connected and fixed via the Velcro hook side 18 and the Velcro loop side 20 within the pre-drilled groove 19. It can be easily removed for cleaning and disinfection.
