A radiotherapy position fixing device

Abstract

The invention discloses a body position fixing device for radiotherapy, which belongs to the technical field of medical instruments. The radiotherapy body position fixing device includes: a horizontal plate, the middle part of the top surface is fixedly connected to the bottom surface of the vertical plate, and the side of the vertical plate in the thickness direction coincides with the side of the horizontal plate; the fixing structure includes two supporting plates, and the two supporting plates are inverted. The figure-of-eight shapes are respectively arranged on the left and right sides of the vertical plate in the thickness direction, and the ends of the support plates are fixedly connected to the top surface of the horizontal plate; the opposite surfaces of the two support plates are fixedly connected to the blocks, and the blocks are far away from the An arc plate is arranged in the direction of the ends of the two supporting plates close to each other, and the inner arc surface of the arc plate is close to the block body. It ensures that the patient's chest wall is stretched consistently due to the fixation of the arm, avoids the error of each treatment activity, improves the accuracy of radiotherapy, and reduces the problem of radiation damage to normal organs caused by treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiation therapy body position fixing device. Background technique [0002] Breast cancer is a phenomenon in which mammary epithelial cells proliferate out of control under the action of various carcinogenic factors. In the early stage of the disease, symptoms such as breast lumps, nipple discharge, and enlarged axillary lymph nodes are often present. In the late stage, cancer cells may metastasize far away, resulting in multi-organ lesions, which directly threaten the patient's life. [0003] Radiation therapy, referred to as radiotherapy, is a local treatment method that kills cancer cells through radiation. It is often used in conjunction with surgery or chemotherapy to reduce local tumor recurrence and improve patient survival. [0004] Radiation therapy has high requirements on the repeatability and accuracy of the treatment position. During the treatment, the up...

AI Technical Summary

Problems solved by technology

[0004] Radiation therapy requires high repeatability of the treatment position. During the treatment, the patient's upper limbs on both sides should be naturally lifted and bent towards the top of the head. The chest wall will cause movement errors because the patient's upper limbs are not accurately fixed, and the position of the chest wall after lifting is relatively inconsistent, which will affect radiotherapy Accuracy increases the risk of radiation damage to normal organs during treatment, so a radiation therapy position fixation device is proposed
