Auxiliary tumor radiotherapy positioning device

Abstract

The invention discloses an auxiliary tumor radiotherapy positioning device. The auxiliary tumor radiotherapy positioning device comprises a support and a plurality of pushing mechanisms, wherein the support is mounted on a treatment bed through a locking plate, the support comprises two mounting plates, the locking plate is mounted at the bottoms of the mounting plates, the two mounting plates are connected through a supporting plate, the two mounting plates are symmetrically distributed relative to the supporting plate, two connecting plates located on two sides of the supporting plate are further arranged between the two mounting plates, the pushing mechanisms are respectively mounted on the connecting plates in a relatively parallel mode, and each pushing mechanism comprises two pushing units. After a patient directly lies on the tops of the pushing mechanisms, the patient and an auxiliary mechanism are pushed to move through the pushing mechanisms, the patient is moved to the middle position of a radiotherapy bed to be pre-positioned, the positioning of the patient is convenient, and the operation of medical staff is simple.

Description

technical field [0001] The invention relates to the technical field of tumor radiotherapy, in particular to a device for assisting positioning in tumor radiotherapy. Background technique [0002] Radiation therapy for tumors is a method of treating tumors with radiation or particle technology. Although radiation can treat benign diseases, it is mainly used to treat malignant tumors. It, together with surgical treatment and drug treatment, constitutes the three major means of treating tumors. Various methods have their different indications and limitations. Different tumors and the same tumor at different stages also require different methods for treatment. About 60% to 70% of malignant tumor patients are at a certain stage of their disease course. Received radiation therapy. [0003] When the doctor needs to perform radiation therapy on the patient, the attending doctor needs to arrange the patient to "position", that is, use the simulated positioning CT machine to locate t...

AI Technical Summary

Problems solved by technology

[0004] In the process of patient treatment, it is necessary to fix the patient's body position to reduce the positioning error. The existing fixed positioning method often uses thermoplastic film to fix the head position of the patient; the precise body position fixation technology, thermoplastic body The phantom position technology is superior to the vacuum cushion and other fixed technologies, with the least positioning error and the least influence on respiratory movement. Method: choose a suitable headrest according to the patient's condition, place it on the base of the head, neck and shoulder board, take a comfortable supine position, and place the head on the On the headrest, immerse the head, neck and shoulder net in water at about 70°C, take it out after the material is transparent and softened for about 2-3 minutes, dip the towel in the water, cover the patient quickly, and keep touching it with both hands to make it close to the skin. Precisely shape the eyebrow arch, eye socket, nose wing, chin, etc. to make contours, repeat the above steps on the neck, shoulders and armpits, etc., to make body surface contours. After the shape is confirmed, the fixing film can be removed to prevent the plastic from continuing to shrink It causes excessive compression when the patient loads the fixed membrane during treatment. Before radiotherapy, the patient needs to lie flat on the body board of the chemotherapy bed, and insert one side of the thermoplastic phantom into the side of the body board. Finally, after placing the entire thermoplastic phantom on the patient's body, the other side of the thermoplastic phantom is inserted into the other side of the body plate, however, after the patient is lying on the chemotherapy bed, the patient's position may It is biased towards one side of the chemotherapy bed. When the thermoplastic phantom is covered, the position needs to be constantly moved until the patient is in the middle of the chemotherapy bed or body board. The positioning of the patient is inconvenient, and the operation of the medical staff is more troublesome.
