Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a low limbs fixing device for radiotherapy.
Background
The efficacy of radiation therapy depends on the sensitivity of the radiation, and the degree to which different tissues and organs, as well as various tumor tissues, respond differently after exposure to radiation. Radiosensitivity is related to the proliferative cycle and pathological grade of tumor cells, i.e., actively proliferating cells are more sensitive than non-proliferating cells, with higher cell differentiation giving lower radiosensitivity and vice versa.
When the radiation therapy is carried out on a single lower limb, the affected lower limb needs to be subjected to posture fixation, the healthy lower limb needs to be protected far away from the ray range, the existing lower limb fixing device for the radiation therapy cannot protect the healthy lower limb while the affected lower limb is subjected to radiation therapy, and aiming at the problem, a lower limb fixing device for the radiation therapy is provided.
