Description
Technical Field
The invention belongs to the technical field of tumor treatment, and particularly relates to a comprehensive tumor radiotherapy bed.
Background
Radiotherapy of tumors is an effective therapy, and for radiotherapy of head and neck tumors, accurate positioning of the head is required, but in the treatment process, the head can only be kept at a height and is not easy to fix, and nursing staff is required to assist the head, so that inconvenience is brought to the medical staff.
The efficacy of radiation therapy depends on the sensitivity of the radiation, and the extent of the response varies from tissue to tissue and from tumor tissue to tumor tissue after exposure to radiation. Radiosensitivity is related to the proliferation cycle and pathological classification of tumor cells, i.e. cells that proliferate actively are more sensitive than cells that do not proliferate, the higher the degree of cell differentiation, the lower the radiosensitivity and vice versa. In addition, the oxygen content of tumor cells directly affects the radiosensitivity, for example, early tumor has small volume, good blood circulation, good curative effect when the hypoxic cells are small, late tumor has large volume, poor blood circulation in tumor and even necrosis in the center, and the radiosensitivity is low; the squamous carcinoma growing in local part has better blood circulation and higher sensibility than the tumors in buttocks and limbs; tumor is locally combined with infection, poor blood circulation (multiple hypoxic cells) and reduced radiosensitivity. Therefore, keeping the irradiated part clean, preventing infection and necrosis is an important condition for improving the sensitivity of radiotherapy.
The existing treatment bed can support and fix the head of a patient at multiple angles through various means so as to achieve the purpose of fixing, but the fixation at multiple angles often occupies a treatment path, which is not reimbursed.
