[0002] Radiotherapy, also known as radiotherapy, is a treatment modality that uses high-energy radiation (such as X-rays, gamma rays, and proton beams) to irradiate tumor cells, targeting them and targeting abnormal cells based on their sensitivity. This treatment method is localized and requires no incisions. Radiotherapy plays a crucial role in cancer treatment, being used in approximately 70% of cancer patients. However, radiotherapy can also cause varying degrees of damage to normal tissues, such as the skin and mucous membranes. Patients may experience symptoms such as burning, itching, scaling, and erythema, as well as systemic reactions such as radiation esophagitis and radiation pneumonitis. Therefore, to prevent unnecessary injury to patients, precise tumor location must be determined during radiotherapy, and patients must be positioned securely during treatment to prevent muscle strain during prolonged radiotherapy. This could lead to inaccurate radiotherapy placement, potentially compromising treatment effectiveness and potentially causing injury.

The handle 4 is a cylindrical handle 4. The cylindrical handle 4 can provide a more comfortable grip for the patient. The cylindrical handle 4 is connected to the upper portion of the lifting component 3. The height of the adjustable handle 4 of the lifting component 3. Different patients have different body shapes and arm lengths. In order to make the armrest adapt to the conditions and needs of various patients and provide patients with a more comfortable radiotherapy posture, the handle 4 is set in an adjustable height form. When necessary, medical staff can accurately set the height of handle 4 to make the patient's position more accurate, so that the customer can avoid unnecessary injuries during radiotherapy. Medical staff can also record the height data of handle 4 when the patient fixes the upper limb. When using, medical staff can adjust the height of handle 4 according to the data of previous patients.

[0032] In a preferred upper limb fixation frame for tumor radiotherapy, a lifting component 3 includes a telescopic rod 304 and a sleeve 300. The sleeve 300 is cylindrical with a circular slide hole in the middle. The telescopic rod 304 is also cylindrical, with a diameter smaller than the inner diameter of the sleeve 300. The telescopic rod 304 is telescopically slidable within the circular slide hole in the sleeve 300, and the handle 4 is mounted on the upper portion of the telescopic rod 304. To provide the lifting function of the lifting component 3, the lifting device adopts the form of a telescopic rod 304 plus a sleeve 300. The telescopic rod 304 is movably disposed within the sleeve 300. Adjusting the length of the telescopic rod 304 relative to the sleeve 300 can adjust the height of the handle 4. This lifting component 3 is simple in structure, reliable and practical, low in cost, and easy to use. It also facilitates disassembly of the entire armrest.

[0033] In another preferred tumor radiotherapy upper limb fixing frame, in order to make the patient have more optional upper limb fixed posture, further adapt to more patients, the lifting component 3 in the utility model is provided with two lifting components 3, and the telescopic rod 304 in the lifting component 3 further comprises a sliding block 305, the sliding block 305 is a T-shaped sliding block 305, a T-shaped sliding hole matched with the T-shaped sliding block 305 is arranged in the handle 4, the sliding block 305 is arranged on the upper portion of the telescopic rod 304, and the telescopic rod 304 is slidably arranged in the sliding hole on the handle 4 through the sliding block 305. The two lifting components 3 are rotatably arranged on the circular connecting rod 202, wherein the through hole arranged on the upper and lower portions of the sleeve 300 in the lifting component 3 is a square sliding hole 301, square connecting rods 201 are arranged on the two sides of the circular connecting rod 202 of the connecting rod body 200, the upper surfaces of the square connecting rods 201 are parallel to the upper surface of the bed plate body 100, and the two lifting components 3 are correspondingly arranged on the square connecting rods 201 on the two sides of the circular connecting rod 202. The sleeve 300 in the lifting component 3 is slidably arranged on the square connecting rod 201 through the square sliding hole 301 arranged on the sleeve 300, when the lifting component 3 slides on the square connecting rod 201 through the square sliding hole 301, the square connecting rod 201 can limit the lifting component 3, and the rotation of the lifting component 3 on the square connecting rod 201 is prevented. It can be known that, in order to make the lifting component 3 on the square connecting rod 201 be perpendicular to the stability of the bed plate 1 in the direction, that is, in order to prevent the lifting component 3 from rotating on the square connecting rod 201, the square sliding hole 301 needs to be more matched with the square connecting rod 201, and the lifting component 3 is less likely to rotate. When in use, in addition to the relaxed upper limb fixed posture that the patient can adopt the normal parallel relaxation of the two arms and then hold the handle 4 with the hands, the patient can also adopt the crossed upper limb fixed posture that the two hands are crossed and held on the two lifting components 3 by adjusting the distance between the two lifting components 3 to a proper distance, and the two lifting components 3 with adjustable distance can also be adjusted according to the conditions of the patient, so that the handrail frame can adapt to more patients.

[0034] In a preferred upper limb fixation frame for tumor radiotherapy, when a patient adopts a relaxed upper limb fixation position, the two lifting components 3 need to be slid onto the circular connecting rod 202. To prevent the lifting components 3 from rotating on the circular connecting rod 202, the lifting components 3 also include a fixing member 6.

When the lifting component 3 is perpendicular to the bed plate body 100, the first fixing hole 203 and the second fixing hole 302 are concentric. The distance between the two first fixing holes 203 is the distance between the two second fixing holes 302 of the two sleeves 300 when the two sleeves 300 are close together. Rotating the fixing member 6 so that it rotates into the second fixing hole 302 and then into the first fixing hole 203 secures the lifting component 3 to the circular connecting rod 202, preventing the lifting component 3 from rotating relative to the circular connecting rod 202. At the same time, when the lifting component 3 slides on the square connecting rod 201, rotating the fixing member 6 causes the fixing member 6 to press against the square connecting rod 201, preventing the lifting component 3 from sliding on the square connecting rod 201.

[0035] In a preferred upper limb fixation frame for tumor radiotherapy, in order to facilitate the control of the height of the telescopic rod 304 extending from the sleeve 300, a third fixing hole 303 is provided on the upper part of the sleeve 300. The third fixing hole 303 is a screw hole that matches the screw rod of the fixing member 6. The fixing member 6 is rotatably set at the third fixing hole 303. Rotating the fixing member 6 can make the fixing member 6 press against the telescopic rod 304 to prevent the telescopic rod 304 from sliding in the sleeve 300, thereby realizing the function of adjusting the height of the lifting component 3.
