Description
Technical Field
The invention relates to the technical field of radiotherapy body frames, in particular to a radiotherapy body frame lifting device and a radiotherapy body frame.
Background
Radiotherapy is a treatment method for inhibiting and killing cancer cells by irradiating tumors with rays of various energies, and aims to continuously improve the local control rate of treatment, further improve the survival rate and/or improve the quality of life by increasing the target dose and/or reducing the radiation damage of normal tissues around the target.
Compared with conventional radiotherapy, the intensity modulated radiotherapy technology has many advantages, the result can reach the maximum dosage of the target area, the minimum irradiated amount of normal tissues around the target area, more accurate positioning and irradiation of the target area, and the most uniform dosage distribution in the target area. Clinical results show that intensity modulated radiation therapy significantly increases the local control rate of tumors and reduces damage to normal tissues, so that the intensity modulated radiation therapy technique can achieve a very high treatment gain ratio and can implement "surgical" highly conformal irradiation. But this technique also brings
The problems to be solved are: (1) because the radiotherapy is carried out in a fractionated irradiation mode, only the accurate posture fixing technology can focus on the intensity adjusting technology, and the possibility of tumor recurrence can be reduced to the maximum extent. However, the existing body position fixing technology has large positioning error every time, so that the repeatability of the patient body position to be treated is difficult to ensure, and the positioning error directly influences the accuracy of treatment. (2) The posture fixation needs to avoid the involuntary movement of the patient in the treatment process and also needs to take the comfort of the patient in the treatment process into consideration. However, the existing posture fixing technology is easy to cause discomfort of a patient, and the intensity-modulated radiation therapy is usually long in treatment time, so that the patient easily generates involuntary body movement in the treatment process, the movement of a tumor target area and a compromised organ is caused, the tumor target area and the compromised organ deviate from the intensity-modulated radiation field, and the insufficient dose of the tumor or the excessive dose of the compromised organ are caused to irradiate.
When carrying out the radiotherapy for tumour patient clinically at present, place patient on the radiotherapy body frame mostly, shine with medical linear accelerator, the radiotherapy body frame that has now is adjusted through medical personnel manually mostly when first body lift adjustment, and hardly carries out accurate regulation to the inclination of radiotherapy body frame according to actual need.
In addition, most functions of the existing radiotherapy body frame are too single, no structure capable of installing an auxiliary positioning device is available, however, for breast cancer or chest, abdomen and pelvic tumors, the arm needs to be lifted or leaned backwards for radiotherapy diseases, if the arm cannot be fixed comfortably and accurately, the repeatability of positioning every time is low, and the patient is easy to move involuntarily in the treatment process to influence the radiotherapy effect.
