Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a radiotherapy positioning body frame plate and a radiotherapy positioning method. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. The radiation includes α, β, γ rays generated by radioactive isotopes and X-rays, electron beams, proton beams, and other particle beams generated by various X-ray therapy machines or accelerators. Approximately 70% of cancer patients need radiotherapy during the treatment of cancer, and about 40% of cancers can be cured by radiotherapy. The role and status of radiotherapy in tumor treatment have become increasingly prominent and have become one of the main means for treating malignant tumors.

[0003] In the existing radiotherapy technology, the deviation of the patient's position is sensed and detected. Although the accurate position deviation can be sensed, the adjustment still requires manual operation by medical staff. Since some patients are relatively large in size, when precise position movement is required, the operation will be complex and laborious, which is not convenient for precise adjustment and control, thus reducing the positioning effect.

[0004] When the applicant applied for the present invention, after retrieval, it was found that a Chinese patent disclosed a "radiotherapy positioning body frame plate and a radiotherapy positioning method" with the application number "202110378828.0". This patent mainly adjusts the radiotherapy body position angle of the patient from various angles by means of linkage with a six-degree-of-freedom parallel robot, with high positioning accuracy and high body position repeatability. However, this structure still requires the cooperation of medical staff for operation, and precise control is needed for accurate positions. There may be errors in the adjustment method of this structure. Therefore, according to the applicant's invention, a precise positioning control device for patients was invented, which solves the problems that for some patients with a relatively large size, when precise position movement is required, the operation will be complex and laborious, and it is not convenient for precise adjustment and control. Summary of the Invention

[0008] To achieve the above object, the present invention is realized through the following technical solutions: A radiotherapy positioning body frame plate, comprising: a fixed bottom plate, a positioning body frame plate and a support plate. Both sides of one end of the fixed bottom plate are fixedly connected with support seats. The top of the support seats is fixedly connected with the positioning body frame plate. A rotating shaft is rotatably connected to the middle of the positioning body frame plate. The middle of one end of the positioning body frame plate is fixedly connected with a support plate. The middle of the top of the support plate is fixedly connected with a headrest. The middle of the top of the headrest is concave. Both the one end and the middle of the positioning body frame plate are provided with moving adjustment plates. Both ends of the moving adjustment plate are slidably fitted with open slots. The moving adjustment plate is square. The middle of the bottom end of the moving adjustment plate is threadedly connected with a second threaded rod. T-shaped slots are opened at the four corners of the moving adjustment plate;

[0013] Preferably, a driving motor is fixedly connected to one end of the upper surface of the fixed bottom plate. A second bevel gear is fixedly connected to the driving end of the driving motor. A first bevel gear is engaged with the bottom side of the second bevel gear. A first threaded rod is fixedly connected to one end of the first bevel gear.

[0014] Preferably, the middle of the first threaded rod is threadedly fitted with the slider. A sliding rod penetrates through the middle of one end of the fixed bottom plate. The top of the sliding rod is fixedly connected with the positioning body frame plate.

[0015] Preferably, a knob is fixedly connected to one end of the second threaded rod.

[0016] A positioning method for a radiotherapy positioning body frame plate includes the following positioning steps:

[0017] Step 1: The patient who needs positioning radiotherapy lies flat on the positioning frame. The foot strap plate and the hand strap plate are provided with strap grooves, which can restrict the patient through the straps. Then, after the platform is accurately positioned, the weight of the buttocks, waist and head can be recorded through the first pressure detection plate, the second pressure detection plate and the third pressure detection plate respectively, so that if there is a weight deviation during the subsequent radiotherapy, it means that the patient has been displaced, which affects the radiotherapy effect.

[0018] Step 2: T-shaped slots are provided at the four corners of the movable adjustment plate. The straps are inserted through the T-shaped slots to clamp the straps in a T-shaped manner, so as to restrict the patient. The position setting of the movable adjustment plate can support the patient's hips and shoulders. When the position is offset, the medical staff can adjust it by turning the knob.

[0019] Step 3: After the knob is turned, the second threaded rod is driven to rotate, and after the rotation, the second threaded rod is threadedly matched with the movable adjustment plate to realize thread movement and displace the patient's body position, so as to facilitate precise positioning control of the patient;

[0020] Step 4: The screw can be rotated to fit the curved flexible plate with both sides of the head to achieve the resistance effect, thereby keeping the head position fixed and increasing the positioning effect;

[0021] Step 5: A driving motor is provided on one side of the top of the fixed base plate, and the driving motor drives the second bevel gear to rotate and engage with the first bevel gear at the bottom, so that the first threaded rod can be rotated. After rotation, the first threaded rod is threadedly matched with the slider to move the position of the rotating shaft. The rotating support rod is supported by the movement of the rotating shaft position, and the rotating shaft on one side of the positioning body frame is rotated and flipped to complete the required adjustment support of the angle.

[0025] 2. The present invention is provided with: a first pressure detection plate, a second pressure detection plate, and a third pressure detection plate. By using the first pressure detection plate, the second pressure detection plate, and the third pressure detection plate to record the weights of the hip, waist, and head positions respectively, it is convenient to detect weight deviation during subsequent radiotherapy, which indicates that the patient has shifted, thus affecting the radiotherapy effect. Through this structure, weight induction can be achieved, weight comparison can be completed, and position deviation can be accurately detected.
