Problems solved by technology

When radiotherapy is performed on parts close to the heart, such as the lungs or esophagus, inaccurate positioning can lead to unexpected damage to the patient's heart. Two studies of patients with lung or esophageal cancer showed that the accuracy of radiotherapy has a significant impact on patient survival. The impact is obvious

Abstract

The invention discloses a precise positioning device for radiotherapy. The precise positioning device comprises a positioning plate, a supporting frame is connected to the top of the positioning plate, a bearing plate is fixedly connected to the top of the supporting frame through a thread, a center operation plate is fixedly connected to the top of the bearing plate through a spring, and symmetric limiting slideways are in fixed nail joint with the top of the center operation plate; an elastic frame is in fixed nail joint with the top of the center operation plate, a waist supporting pillow is in fixed nail joint with the elastic frame, a guide rail is in rivet joint with the periphery of the outer side of the center operation plate, and the center operation plate is provided with an X-ray image collecting module, an infrared positioning and tracking module and a daily positioning and verification module. According to the precise positioning device for radiotherapy, through the addition of the X-ray image collecting module, the infrared positioning and tracking module and the daily positioning and verification module, a radiotherapy plan can be self-adaptively adjusted, and thus the precision and quality of the radiotherapy are ensured.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a precise positioning device for radiotherapy. Background technique [0002] With the advancement of medical technology, there are now more and more treatment methods that can effectively treat various tumors and cancers. In addition to drug therapy and surgical treatment, radiotherapy is also an extremely important form of cancer treatment today. Although radiotherapy has only been around for a few decades, it has developed rapidly and is now an integral part of cancer treatment. Radiotherapy is a treatment method that irradiates tumors with rays of different energies to inhibit and kill cancer cells. Its essence is to directly bombard tumor cells with high-energy particles, but this attack is an indiscriminate attack, that is, whether it is cancer cells or normal cells. cells will be damaged. Therefore, although radiotherapy is effective, it also has cert...
