Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a radiotherapy couch. Background Art

[0002] Radiation therapy is a form of treatment that uses ionizing radiation. The principle is that the energy from large amounts of radiation can damage a cell's chromosomes, causing it to stop growing and thus eliminating rapidly dividing and growing cancer cells. Radiation therapy is most commonly used as a direct or adjuvant treatment for cancer. Furthermore, prior to a bone marrow transplant, the entire body may be irradiated to eliminate any malignant cancer or HIV cells. Other conditions, such as trigeminal neuralgia, can also be treated with radiation.

[0003] The Chinese patent application number 202321041003.0 discloses a radiotherapy bed. The patient lies flat on the bed board by grasping the limit frame through the grasping groove. The hydraulic lifter is activated to push the fixed frame, connecting plate, bed board and patient to move and adjust the irradiation height. The linear motor and the limit sliding assembly are activated to cooperate with the moving mechanism to move the bed board and patient horizontally and vertically through the connecting plate, fixed frame, limit block and slide groove to adjust the patient's irradiation position. This achieves the goal of facilitating the adjustment of the patient's lesion position during irradiation, avoiding the situation of off-target or missed target due to the patient's resistance or discomfort.

[0004] However, when using the limit frame of this device, the limit frame is large in size. When the bed board on which the limit frame is installed is moved, the limit frame is likely to interfere with other medical devices. In addition, there are many limit frames, and it is laborious to install and remove the limit frames, which makes it inconvenient to quickly use the radiotherapy bed and fix the patient's position to avoid displacement of the patient and the bed board when the bed board is moved.
