With technological advancements, this field is continuously progressing towards improved precision, enhanced comfort, and personalized treatment, while also exploring more intelligent and efficient solutions to further optimize treatment outcomes and safety.

[0003] A search revealed a breast radiotherapy support frame proposed in Chinese Patent (Announcement No.: CN219595661U), comprising a backplate assembly, a base plate assembly, and an arm support assembly. The backplate assembly includes a backplate and a backplate support plate. The base plate assembly includes a base plate, a hip clamping device, and an angle adjustment device. The backplate support plate is installed below one end of the backplate, and the arm support assembly is installed above one end of the backplate, with the arm support assembly installed on both sides above the backplate. The angle adjustment device is installed at one end of the base plate, and the hip clamping device is installed at the other end of the base plate. The backplate is tilted and placed on the base plate via the installation of the backplate support plate and the angle adjustment device. This invention can achieve high-precision and individualized positioning and fixation during breast radiotherapy according to the needs of breast radiotherapy and the characteristics of different patients' bodies. It can improve radiotherapy accuracy, reduce errors, improve the positioning efficiency of technicians, and improve the comfort of patients during treatment.

[0004] While the aforementioned patents can achieve the supporting function, they still have the following shortcomings during use: The aforementioned equipment requires complex adjustments by medical staff to better suit patients. Adjustments are needed for each use by different patients, resulting in a low level of automation. As the number of patients increases, the manual adjustment process may become more cumbersome and prone to operational errors, affecting the convenience and stability of long-term use.

[0017] In the scheme of this application: 1. Multiple support components provide precise support for different parts of the patient's body with a high degree of automation and close conformity, ensuring stable positioning of the breast and target area during treatment and improving the precision and dosage accuracy of radiotherapy. Automated adjustment reduces manual operation by medical staff, improving operational efficiency and repeatability. Close conformity to the patient's body shape not only enhances comfort and tolerance but also reduces the risk of postural deviation, enabling personalized and intelligent radiotherapy support solutions and improving overall treatment effectiveness and clinical applicability. 2. By connecting different connectors on the lateral and longitudinal adjustment components, the height of the support components at different positions can be adjusted according to the patient's body shape, providing real-time and personalized support. This ensures that different parts of the body maintain a stable posture that conforms to the human body curve during treatment, improving positioning accuracy and the accuracy of radiotherapy dosage, while protecting surrounding healthy tissues. The real-time adjustment function can instantly compensate for minor changes in the patient's body position, enhancing the safety and repeatability of the treatment process. The modular and adjustable design not only improves patient comfort, reduces local pressure and discomfort from prolonged fixation, but also optimizes the operating procedures of the treatment team, reduces human error, and improves treatment efficiency and accuracy. 3. The third motor drives the integrated optical distance sensor to reciprocate on both sides of the patient's body via the first toothed synchronous belt and connecting block. This allows for real-time monitoring of the patient's posture and adjustment of the support component height based on real-time changes. This improves the accuracy of radiotherapy positioning, ensures that the breast and surrounding tissues maintain precise positions during treatment, reduces the radiation risk to healthy tissues, and enhances patient comfort by adjusting the support height in real time. It also disperses local pressure, avoids discomfort caused by prolonged fixed postures, and improves the repeatability and efficiency of treatment. The automated system reduces manual intervention, optimizes the treatment process, and ensures consistency in each treatment. 4. By monitoring the patient's posture, the second electric push rod is simultaneously controlled to drive the bottom support frame for real-time height adjustment, thereby effectively controlling the patient's abdominal fluctuations, improving radiotherapy positioning accuracy, ensuring that the breast and target area remain in the correct position during treatment, reducing the risk of radiation exposure to healthy tissues, and dynamically adjusting the support height to adapt to changes in breathing and posture, enhancing patient comfort, reducing discomfort caused by prolonged fixed postures, improving the repeatability and safety of treatment, and automatically adjusting to reduce manual intervention, ensuring consistent posture for each treatment session. Personalized support can be achieved based on differences in the patient's breathing amplitude and posture, improving the intelligence and precision of the support system.

Slider 36 is located inside the adjustment end of the horizontal adjustment component; A connecting component is located at the top of slider 36, and the connecting component is moved by slider 36; The hydraulic assembly, located at the bottom and top of the base frame 1, is used to supply hydraulic oil into the connecting assembly and to supply the hydraulic oil into the corresponding support assembly through the connecting assembly.

[0022] like Figure 1-13 As shown, in a preferred embodiment, based on the above method, the supporting component further includes a hydraulic cylinder 51 opened on the inner side of the bottom wall of the supporting box 5, a sealing ring 52 fixedly connected to the inner side of the top wall of the hydraulic cylinder 51, a piston 53 slidably connected to the inner side of the hydraulic cylinder 51, a supporting column 54 fixedly connected to the top wall of the piston 53, the top end of the supporting column 54 slidably connected to the bottom wall of the elastic partition 55, and the bottom wall of the hydraulic cylinder 51 fixedly connected to and communicating with the top end of the conveying pipe 24. By controlling the amount of hydraulic oil inside the hydraulic cylinder 51, the height of the piston 53 inside the hydraulic cylinder 51 can be adjusted, thereby effectively adjusting the lifting height of the support column 54. Through the cooperation of multiple support columns 54, the system can adapt to the patient's body shape and adjust the required support posture according to radiation needs.

[0023] The connecting assembly includes a first fixed hemispherical plate 22 fixedly connected to the top wall of the limiting frame 21, and a connecting head 23 corresponding to the supporting assembly fixedly connected to the inner side of the top wall of the connecting head 23. The top end of the connecting head 23 is fixedly connected to the bottom end of the conveying pipe 24. The first fixed hemispherical plate 22 is supported by the limiting frame 21, and the first fixed hemispherical plate 22 simultaneously supports and fixes multiple connectors 23.

[0024] The lateral adjustment assembly includes a first motor 3 fixedly connected to one side of the outer wall of the limiting frame 21, and a first transmission column 31 rotatably connected to both sides of the top of the limiting frame 21. One side of the first transmission column 31 is fixedly connected to the output end of the first motor 3. A connecting wall 32 is fixedly connected to the bottom wall of the first transmission column 31. A connecting column 33 is fixedly connected to the top wall of the middle section of the connecting wall 32. A support ring 34 is fixedly connected to the top of the connecting column 33. A sliding groove 35 is opened on the outer wall of the support ring 34. The sliding groove 35 is slidably connected to the slider 36. First limiting rings 39 are fixedly connected to the outer walls on both sides of the support ring 34. The first limiting rings 39 are symmetrically distributed about the central axis of the support ring 34. The first motor 3 drives the bottom connecting wall 32 to rotate via the first transmission column 31. At the same time, the connecting wall 32 drives the support ring 34 and the first limiting ring 39 to rotate synchronously via the connecting column 33. This causes the sliding groove 35 on the inner side of the support ring 34 to rotate synchronously with the support ring 34 and the first limiting ring 39.

[0025] The longitudinal adjustment assembly includes a second motor 4 fixedly connected to the outer wall of one side of the limiting frame 21, and a second transmission column 41 rotatably connected to both sides of the top of the limiting frame 21. One side of the second transmission column 41 is fixedly connected to the output end of the second motor 4. A second fixed hemispherical plate 42 is fixedly connected to the outer wall of the second transmission column 41. The second fixed hemispherical plate 42 is slidably connected to the first fixed hemispherical plate 22. The inner diameter of the first fixed hemispherical plate 22 is the same as the outer diameter of the second fixed hemispherical plate 42. Two second limiting rings 43 are fixedly connected to both sides of the middle section of the inner wall of the second fixed hemispherical plate 42. The second limiting rings 43 are symmetrically distributed about the central axis of the slider 36. The second motor 4 drives the second fixed hemispherical plate 42 and the second limiting ring 43 to rotate longitudinally via the second transmission column 41. A row of through holes corresponding to the number and position of the connectors 23 are opened in the middle section of the second fixed hemispherical plate 42 in the direction parallel to the second limiting ring 43.

[0026] The connecting component includes a limiting post 37 fixedly connected to the top wall of the slider 36, a connecting pipe 38 fixedly connected to the middle section of the top wall of the limiting post 37, the limiting post 37 being slidably connected to the second limiting ring 43, the connecting pipe 38 being slidably connected to the bottom wall of the second fixed hemispherical plate 42, and sealing plates 44 fixedly connected to both sides of the top of the limiting post 37, the sealing plates 44 being slidably connected to the second limiting ring 43; When the support ring 34 and the first limiting ring 39 rotate laterally, they drive the slider 36, the limiting post 37, and the connecting pipe 38 to rotate laterally synchronously, thereby adjusting the position of the connecting pipe 38 at the top laterally. At the same time, when the second fixed hemispherical plate 42 and the second limiting ring 43 rotate longitudinally, the second limiting ring 43 pushes the limiting post 37, the slider 36, and the connecting pipe 38 to slide longitudinally within the slide groove 35, thereby adjusting the longitudinal position of the connecting pipe 38. Meanwhile, when the limiting post 37 rotates laterally, it drives the 44 on both sides to rotate synchronously, so that the 44 can seal the through holes opened on the second fixed hemispherical plate 42. Only the through hole connected to the connecting pipe 38 can allow hydraulic oil to flow through, while the others are sealed. At the same time, the second fixed hemispherical plate 42 seals the bottom ends of the remaining connectors 23 outside the through hole position.

[0027] The hydraulic assembly includes a liquid storage tank 6 fixedly connected to one side of the bottom of the base frame 1. A delivery pump 61 is fixedly connected to one side of the outer wall of the liquid storage tank 6. A delivery pipe 62 is fixedly connected to the output end of the delivery pump 61. The top end of the delivery pipe 62 passes through the slider 36, the limiting post 37 and the connecting pipe 38. The hydraulic oil in the storage tank 6 is drawn by the delivery pump 61 and delivered into the connecting pipe 38 through the delivery pipe 62. The hydraulic oil is then delivered into the hydraulic cylinder 51 through the connector 23 and the delivery pipe 24 via the connecting pipe 38.

[0028] The top plate 11 has grooves 7 on both sides, which are symmetrically distributed about the central axis of the top plate 11. Two third motors 71 are fixedly connected to the side wall of the top plate 11. A first toothed synchronous belt 72 is rotatably connected to the inside of the groove 7. One rotating end of the first toothed synchronous belt 72 is fixedly connected to the output end of the third motor 71. A connecting block 73 is fixedly connected to the middle section of the first toothed synchronous belt 72. An integrated optical distance sensor 74 is fixedly connected to the side of the connecting block 73 away from the first toothed synchronous belt 72. The integrated optical distance sensor 74 is slidably connected to the top plate 11. A second toothed synchronous belt 75 is provided inside the groove 7. The second toothed synchronous belt 75 is sleeved on the outside of the first toothed synchronous belt 72 to seal the opening of the groove 7.

[0029] The top wall of the support box 5 is connected to the door frame 8 in the middle section. The middle section of the door frame 8 is slidably connected to the sliding sleeve 81. The inner side of the sliding sleeve 81 is provided with a fixing bolt. The outer wall of one side of the sliding sleeve 81 is detachable to the second electric push rod 82. The output end of the second electric push rod 82 is fixedly connected to the support frame 83. The first toothed synchronous belt 72 is driven by the third motor 71 to rotate within the groove 7. Simultaneously, the first toothed synchronous belt 72 drives the integrated optical distance sensor 74 to reciprocate on the outside of the top plate 11 via the connecting block 73. This allows the integrated optical distance sensor 74 to monitor the patient's posture in real time and upload the monitoring data to the terminal. The terminal's calculation model (which is a commercially available model and will not be described) is used to derive the operating results (the matching external devices are all existing technologies and will not be described). These results are then sent to the first motor 3, the second motor 4, the delivery pump 61, and the second electric push rod 82 to adjust the height of the corresponding support column 54 and the height of the support frame 83 in real time. This allows for adjustment of the patient's posture and adaptation to changes in the patient's body position, making the device suitable for various radiotherapy methods and postures.

[0030] Multiple first electric push rods 12 are detachably connected to the top wall of one side of the base frame 1. The output end of the first electric push rod 12 is rotatably connected to the arm support 13. The first electric push rod 12 can drive the arm support 13 to rise and fall, thereby supporting the patient's arm during radiotherapy.

[0031] Specifically, when using this breast radiotherapy positioning and support structure: First, the patient lies on the elastic mesh 55. Then, the third motor 71 drives the integrated optical distance sensor 74 to slide on the outside of the top plate 11 via the first toothed synchronous belt 72 and the connecting block 73, thereby scanning the patient's body posture and constructing a three-dimensional surface topography map of the supported breast and surrounding chest wall in real time. The data is then uploaded to the terminal. The patient's body posture data is processed through a calculation model, and the calculation results are then sent to the first motor 3, the second motor 4, and the delivery pump 61 to control the first motor 3, the second motor 4, and the delivery pump 61 to run synchronously. During the process, the first motor 3 drives the connecting wall 32 to rotate laterally via the first transmission column 31. At the same time, the connecting wall 32 drives the support ring 34 and the first limiting ring 39 to rotate laterally via the connecting column 33. This causes the top slider 36, limiting column 37, connecting tube 38 and 44 to rotate laterally between the second limiting ring 43, thereby adjusting the lateral position of the connecting tube 38. Then, the second motor 4 drives the second fixed hemispherical plate 42 and the second limiting ring 43 to rotate longitudinally through the second transmission column 41, so that the through hole opened at the top of the middle section of the second fixed hemispherical plate 42 is aligned with the corresponding connector 23, and the connecting pipe 38 and the corresponding connector 23 are connected. Then, the hydraulic oil stored in the reservoir 6 is extracted by the delivery pump 61 and delivered to the connecting pipe 38 through the delivery pipe 62. After that, the hydraulic oil is delivered to the corresponding hydraulic cylinder 51 through the connecting pipe 38 via the connector 23 and the delivery pipe 24, thereby pushing the piston 53 and the support column 54 to the top and raising the height of the support column 54. By adjusting the height of the corresponding support column 54 and using multiple support columns 54, the patient can be effectively supported and can be adapted to the patient's body shape. Next, the gantry 8 is snapped into the corresponding position in the middle of the support box 5. Then, the second electric push rod 82 drives the support frame 83 to move down to support the patient's abdomen. Then, the thermoplastic film is heated and covered on the patient's breast area, and then cooled to provide effective support for the patient's breast area. During radiotherapy, the integrated optical distance sensor 74 constantly moves back and forth on both sides of the patient to monitor the body posture in real time. If any changes occur, the body posture will be adjusted in real time through the control device.
