Radiation therapy protective frame for head and neck tumors

Abstract

The disclosure belongs to the field of medical devices, and discloses a head and neck tumor radiotherapy protection frame, which includes a carrier plate for a patient lying flat, and a radiation shield straddling the carrier plate along the width direction of the carrier plate, the radiation shield Sliding along the length direction of the carrier plate; a neck support area and a head support area are provided on the carrier plate; a first support plate capable of sliding along the length direction of the carrier plate is provided on the neck support area, and the first support plate An airbag cushion is arranged on the headrest; a movable hole is opened on the head support area, a headrest is arranged in the middle of the movable hole, and arc-shaped baffles capable of clamping each other are arranged on both sides of the headrest. The disclosure adjusts the arc-shaped baffle, and the arc-shaped baffle limits the position of the patient's head on the headrest, so that the patient's head and the headrest remain relatively fixed, preventing the patient's head from shaking left and right, and avoiding "" Phenomena such as "artifacts" affect the accuracy of diagnosis.

Description

technical field [0001] The disclosure belongs to the field of medical devices, and in particular relates to a protective frame for radiation therapy of head and neck tumors. Background technique [0002] Radiation therapy plays an important role in the comprehensive treatment of tumors. In the treatment of all malignant tumors, about 70% of the patients require the participation of radiation therapy. In recent years, with the development of science and technology, medical imaging, computer technology, many The leaf collimator is closely combined with accelerator technology, and precise radiotherapy technologies such as three-dimensional conformal radiotherapy, intensity-modulated radiotherapy, and image-guided radiotherapy have been successively applied in clinical practice, which has led to the rapid development of radiotherapy. [0003] Radiation therapy for tumors is an effective therapy. For head and neck tumor radiation therapy, it is required to accurately locate the h...

AI Technical Summary

Problems solved by technology

[0003] Radiation therapy for tumors is an effective therapy. For radiation therapy of head and neck tumors, accurate positioning of the head is required. The positioning method: one is to draw a calibration line on the head for positioning. This method of marking the calibration line is very simple , but in the course of treatment, the head and neck are not easy to fix, sometimes with the assistance of nurses, when the head shifts or rotates, it can affect the curative effect; the second is to place the head in a mold for fixation, although it can be positioned accurately, Fixation is firm, but the patient's head is in the mold, increasing discomfort
