Radiotherapy body position fixing device

Abstract

The invention discloses a radiotherapy body position fixing device, and belongs to the technical field of medical instruments. The radiotherapy body position fixing device comprises: a horizontal plate, wherein the middle of the top face of the horizontal plate is fixedly connected with the bottom face of a vertical plate, and the side face of the vertical plate in the thickness direction coincides with the side face of the horizontal plate; and a fixing structure which comprises two supporting plates, wherein the two supporting plates are arranged on the left side and the right side of the vertical plate in the thickness direction in an inverted splayed shape, the ends of the supporting plates are fixedly connected to the top face of the horizontal plate. Block bodies are fixedly connected to the opposite surfaces of the two supporting plates, arc plates are arranged in the directions, away from the ends, close to each other, of the vertical plate and the two supporting plates, of the block bodies, and the inner arc surfaces of the arc plates are close to the block bodies. The chest wall of the patient is ensured to be stretched consistently due to the fixation of the arm, the activity error of each treatment is avoided, the radiotherapy accuracy is improved, and the problem of radioactive injury to normal organs caused by treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radiotherapy body position fixing device. Background technique [0002] Breast cancer is a phenomenon in which breast epithelial cells proliferate uncontrollably under the action of various carcinogenic factors. In the early stage of the disease, symptoms such as breast lumps, nipple discharge, and axillary lymph node enlargement are often manifested. In the late stage, cancer cells may metastasize to distant places and cause multiple organ lesions, which directly threaten the lives of patients. [0003] Radiation therapy, referred to as radiotherapy, is a local treatment 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 requires high repeatability of the treatment position. During the treatment, the patient's upper limbs on bo...

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
