[0002] Radiation therapy is considered a key and core treatment in the field of tumor management, achieving its therapeutic effect primarily through a unique mechanism of action. The radiation is used to destroy the DNA structure of tumor cells and can further induce apoptosis, the natural death of tumor cells according to the body's programmed response. This dual action of inhibiting proliferation and inducing apoptosis ultimately achieves effective tumor control. This treatment has a wide range of applications and is widely and effectively used in the treatment of various benign and malignant tumors, helping numerous patients combat cancer.

[0019] Combined with Fig. It is evident that a limiting component (5) is provided at an upper end of the mounting plate (305), the limiting component (5) comprises a threaded bore (501), the threaded bore (501) is provided at the upper end of the mounting plate (305), an inner side of the threaded bore (501) is threaded to a threaded column (502), a lower end of the threaded column (502) is fixedly connected to a limiting plate (503), an end of the limiting plate (503) is fixedly connected to a cover plate (504), and a limiting groove (505) is provided on an inner side of the mounting plate (305).

[0020] Specifically, the threaded column (502) is rotated so that it is rotated within the threaded bore (501) at the top of the mounting plate (305), the limiting plate (503) is driven up and down along the limiting groove (505) on the inside of the mounting plate (305) for movement, the height of the cover plate (504) is adjusted, the rubber disc (6) on the inside of the cover plate (504) limits the patient's head and neck, preventing displacement of the head and neck during the radiation treatment process, ensuring that the radiation treatment acts precisely on the head area, thus increasing the effectiveness of the radiation treatment.

[0021] Combined with Fig. and Fig. It can be seen that a storage container (4) is fixedly arranged on the top of the mounting seat (1) and a radiation treatment cover (7) is fixedly arranged on the top of the mounting seat (1).

[0022] Specifically, the storage container (4) serves to store the patient's head, to provide a stable support base for the head, the radiation treatment cover (7) can fulfill a certain protective function for the patient's head in the radiation treatment process, reduce unnecessary scattering of radiation, and ensure the accuracy of the radiation treatment area.

[0023] Combined with Fig. and Fig. It can be seen that one end of the double-threaded rod (302) is rotatably connected within the mounting seat (1), and a lower end of the mounting plate (305) is slidably connected to the top of the mounting seat (1).

[0024] Specifically, the double-threaded rod (302) is arranged to rotate within the mounting seat (1). This ensures the stable rotational movement of the double-threaded rod (302) when driven by the electric motor (301), prevents wobbling or displacement due to unstable fixation of the two ends, and the mounting plate (305) rests with its lower end tightly against the surface of the top of the mounting seat (1).

[0028] Specifically, the rubber disc (6) fully conforms to the curvature of the inner surface of the cover plate (504). When the cover plate (504) contacts the patient's head and neck, the rubber disc (6) can tightly enclose both sides of the head and neck, preventing direct contact of the skin with the cover plate (504). Its elastic deformation increases the frictional force with the head and neck, improves the stability of the fixation, effectively dampens any slight vibrations generated during the radiation treatment process, and ensures patient comfort and safety during long-term radiation treatment.

[0029] Combined with Fig. It can be seen that the width of the boundary plate (503) corresponds to the width of the boundary groove (505), and that one side of the boundary plate (503) is slidably connected to an inside of the boundary groove (505).

[0030] Specifically, the width of the limiting plate (503) matches the width of the limiting groove (505). When the limiting plate (503) is driven upwards and downwards by the threaded column (502), one side of the limiting plate (503) can slide close to the inner wall of the limiting groove (505). The movement path of the limiting plate (503) is restricted, and its displacement to the left or right during the movement process is prevented. A stable ascent or descent of the cover plate (504) in the vertical direction can always be maintained to prevent the fixing effect from being affected by the positional displacement of the cover plate (504).

[0031] Combined with Fig. It can be seen that the diameter of the threaded column (502) corresponds to that of the threaded bore (501), and the length of the threaded column (502) corresponds to the length of the mounting plate (305).

[0032] Specifically, the diameter of the threaded column (502) matches the diameter of the threaded bore (501), ensuring that when turning the threaded column (502) within the threaded bore (501) a stable screw drive can be enabled, preventing the loosening or jamming of the threaded connection, and guaranteeing the accuracy and reliability of the height adjustment of the cover plate (504).

[0033] Operating principle: The electric motor (301) is started, which drives the double-threaded rod (302) to rotate, causing the sliding pieces (303) to move in the axial direction of the double-threaded rod (302). The mounting plate (305) is driven to slide within the sliding groove (304) on the top of the mounting seat (1). The distance between the mounting plates (305) can be adjusted on both sides to accommodate the size of the head and neck of different patients. The threaded column (502) is rotated so that it rotates within the threaded bore (501) at the top of the mounting plate (305). The limiting plate (503) is driven up and down along the limiting groove (505) on the inside of the mounting plate (305). The height of the cover plate (504) is adjusted. The rubber disc (6) on the inside of the cover plate (504) limits the patient's head and neck.The displacement of the head and neck during the radiation treatment process is prevented; the patient's head and neck are supported within the storage container (4) at the top of the mounting seat (1); the radiation treatment cover (7) is provided on the outer circumference to ensure the stability of the radiation treatment process and the accuracy of the radiation function.
