A tumor radiotherapy fixation frame

Abstract

The invention relates to the technical field of fixing frames, in particular to a tumor radiotherapy fixing frame. The tumor radiotherapy fixing frame comprises a base plate, a vertical plate is connected to the upper end of the base plate, the outer side of the vertical plate is provided with a first mounting plate, a fixed plate is connected to the outer side of the first mounting plate, the outer side of the first mounting plate is provided with a movable plate and a first sliding groove, and the outer side of the movable plate is provided with a first sliding block movably connected with the movable plate; a fixing cover is connected to the outer side of the first mounting plate, a motor is mounted in an inner cavity of the fixing cover and connected with a rotating rod through a speedreducer, a rectangular movable frame is connected to the end, away from the speed reducer, of the rotating rod, a supporting rod is connected to the left side of the rectangular movable frame, and the left side of the supporting rod is provided with a first supporting plate. The tumor radiotherapy fixing frame is reasonable in structural design, high in practicability, beneficial to improving thefixing effect and capable of adjusting the fixing angle and improving the therapy effect.

Description

technical field [0001] The invention relates to the technical field of fixing frames, in particular to a fixing frame for tumor radiotherapy. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors. [0003] At present, there are thermoplastic films, negative pressure bags and other fixing devices for the radiotherapy of head and neck tumors and thoracic and abdominal tumors, which better solve the problem of fixing head, neck...

AI Technical Summary

Problems solved by technology

[0003] At present, there are thermoplastic films, negative pressure bags and other fixing devices for the radiotherapy of head and neck tumors and thoracic and abdominal tumors, which better solve the problem of fixing head, neck and body tumors. The location of lower limb tumors varies greatly. At present, clinical treatment usually relies on traditional nail shoes for radiotherapy fixation. Although nail shoes can solve the problem of radiotherapy fixation for malignant tumors of the lower limbs, they must be made according to the size of each patient's foot, and their use is limited. Its fixation effect is poor, and the fixation angle cannot be changed, which will easily affect the effect of treatment. Therefore, we provide a tumor radiation therapy fixation frame to solve this problem
