Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a positioning device for radiotherapy of skull tumors. Background Art

[0002] Radiotherapy for head tumors is of great significance in the treatment of head tumors. By irradiating tumor tissue, tumor growth can be controlled to the maximum extent, helping patients improve treatment effects and survival rates. During the treatment process, in order to more accurately perform radiotherapy on head tumors, a specific head positioning device and mask are generally used to fix the patient's head to ensure that the patient's head is stable and motionless, allowing the radiation beam to accurately irradiate the tumor tissue, maximizing the killing of malignant cells while minimizing damage to surrounding normal tissues.

[0003] However, it is not taken into consideration that due to the different locations of head tumors in different patients, ordinary head positioning devices can only fix the patient's head in a lying position. For tumors in some special locations, such as when the patient needs to adopt different postures such as side lying, high lying, and low lying, the head positioning device is not convenient for positioning the patient's head and keeping the patient's head stable when irradiating the tumor.

At this time, the support plate 3 will rotate with the deflection angle of the connecting bracket 12, thereby driving the patient's head to rotate. The pointer 17 is driven to rotate by rotating the adjusting rod 2 14, thereby driving the support plate 3 on the connecting bracket 12 to deflect in the rotation direction of the rotating frame 10, and driving the patient's head to adjust the high or low position.

By rotating the rotating rod 20, the movable sleeve 21 is driven to move to both sides respectively, and the support rod 22 is driven to move accordingly, so that the support rod 22 changes the distance between the lying plate 2 on the surface of the connecting plate 6 and the fixed shell 1, and one side of the lying plate 2 is lifted to achieve the purpose of adjusting the patient's torso position. This method can be combined with the fixation of the patient's head position, and can better meet the clinical needs of various special body position fixations.

[0035] Furthermore, the lifting reading member includes a scale 23 rotatably mounted on the side of the lying board 2, a slider 24 is fixedly mounted on the surface of the fixed shell 1, and the end of the scale 23 away from the lying board 2 is slidably mounted in the slider 24.

At this time, if the patient's head needs to be in a sideways position, the rotating handle 25 can be clamped on the adjusting rod 13, and the worm 9 can be driven by rotating the adjusting rod 13, and the worm 9 can be rotated to drive the turbine 11 to rotate, and then the connecting bracket 12 is driven to deflect in the direction of rotation of the turbine 11. At this time, the support plate 3 will rotate with the deflection angle of the connecting bracket 12, thereby driving the patient's head to rotate, and with the design of the pointer 2 18 and the angle ruler 2 16, after rotating to the appropriate position, the pointer 2 18 can be observed at the angle. The pointing angle on the angle ruler 16 is recorded for the patient to adjust the angle of the side elevation for the next radiotherapy. If the patient's head needs to be in a high or low elevation state, the rotating handle 25 can be clamped on the adjusting rod 14, and the pointer 17 can be rotated by rotating the adjusting rod 14, thereby driving the support plate 3 on the connecting bracket 12 to deflect the angle along the rotation direction of the rotating frame 10, and driving the patient's head to adjust the high or low elevation position. In addition, with the design of the pointer 17 and the angle ruler 15, after rotating to the appropriate position, the pointing angle of the pointer 17 on the angle ruler 15 can be observed and recorded for the patient to adjust the angle of the side elevation for the next radiotherapy. Through the combination of these two methods, not only can the patient's position be repeated during the next radiotherapy, but the fixed angle can also be flexibly adjusted according to the patient's radiation needs.

[0038] It is worth mentioning that, taking into account the different specific conditions and treatment plans of different patients, a rotating rod 20 is provided, and the rotating handle 25 is clamped on the rotating rod 20. The rotating rod 20 is rotated to drive the movable sleeve 21 to move to both sides respectively, and the support rod 22 is driven to move accordingly, so that the support rod 22 changes the distance between the lying plate 2 on the surface of the connecting plate 6 and the fixed shell 1. When the side of the lying plate 2 close to the mounting shell 5 is lifted to a suitable position, the distance between the scale 23 and the fixed shell 1 can be observed and recorded to facilitate the adjustment of the patient's torso position during the next radiotherapy. This method can better meet the clinical needs of special body position fixation. Since the patient needs to maintain a fixed position for a long time during the treatment, lifting part of the torso according to the patient's own needs can reduce the patient's discomfort and anxiety and improve the patient's comfort.
