Description

Technical Field

[0001] This utility model relates to the field of tumor radiotherapy technology, specifically to an adjustable-angle tumor radiotherapy positioning frame. Background Technology

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. Radiation includes alpha, beta, and gamma rays produced by radioactive isotopes, as well as X-rays, electron beams, proton beams, and other particle beams produced by various X-ray therapy machines or accelerators. During tumor radiotherapy, a positioning frame is needed to immobilize the patient.

[0003] Currently, a Chinese patent has disclosed a pelvic tumor radiotherapy fixation frame (authorization announcement number CN219050151U). The fixation frame can not only restrain the abdomen, but also restrain the patient's hip joint to prevent hip joint movement from causing pelvic displacement. The fixation frame can adjust the height of the thigh, using the change in thigh height to traction the hip joint, and using the traction of the hip joint to adjust the tilt angle of the pelvis, providing a better irradiation angle for radiotherapy. At the same time, the fixation frame can also adjust the external rotation of the thigh, fixing the thigh when it is spread to a suitable angle to fully expose the pelvic structure and provide more possibilities for the selection of the radiation incident angle.

[0004] According to the aforementioned references, in this device, a thermoplastic positioning membrane is attached to the abdomen, and the locking blocks of the first and second tension locking blocks on both sides are engaged with the sliding fixing seat. The fastening bolts are inserted into the tension adjustment groove, so that the thermoplastic positioning membrane is attached to the abdomen. The patient's lower limbs are placed on the left lower limb restraint mechanism and the right lower limb restraint mechanism, respectively. The threaded lifting rod will move vertically upward under the constraint of the limiting slide groove to adjust the height of the left and right thighs. However, when the patient is performing different body position tests, the thermoplastic positioning membrane does not provide ideal fixation for the patient's body, and it is inconvenient to adjust and fix it according to the change of the patient's body position, which reduces the effectiveness of the device.

[0005] Based on this, the present invention designs an adjustable-angle tumor radiotherapy positioning frame to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable angle tumor radiotherapy positioning frame.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 An adjustable-angle tumor radiotherapy positioning frame includes a placement plate 1, mounting plates 2 slidably connected to both sides of the placement plate 1, and an adjustment mechanism 3 disposed on the inner wall of the mounting plate 2. A movable plate 301 is slidably connected to the inner wall of the mounting plate 2. Two lead screws 302 are threadedly connected to one side of the movable plate 301. One end of the lead screw 302 passes through the movable plate 301 and is fixedly connected to a first fixing block 303. A first protective pad 304 is fixedly connected to one side of the first fixing block 303. A fixing component 311 is disposed at one end of the placement plate 1.

[0029] The patient lies on the placement plate 1 and is positioned for the examination. The mounting plate 2 is moved to the appropriate position by sliding to one side via the electric slide rail 310. Then, the moving plate 301 drives the lead screw 302 to move up and down with the first fixing block 303 and the first protective pad 304. Manually rotating the lead screw 302, which is threadedly connected to the moving plate 301, moves the first fixing block 303 and the first protective pad 304 to one side to support and fix the patient's body, preventing displacement and shaking during chemotherapy.
