Combined positioning frame device convenient for chest tumor radiotherapy

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a combined positioning frame device convenient for chest tumor radiotherapy, which comprises a placing bed and an adjusting frame, the lower end of the placing bed is provided with supporting legs for supporting, the upper end of the placing bed is provided with an arc-shaped pad for improving the comfort of a patient, the arc-shaped pad is in an arc-shaped groove shape, and the adjusting frame is provided with a positioning groove. The side end of the placing bed is provided with a sliding groove used for sliding of the adjusting frame, through arrangement of a first clamping block, one end of the first clamping block is fixed to a P-shaped block, the other end of the first clamping block is connected with a second clamping block through a T-shaped groove, through rotation of a T-shaped rod, the angle of the first clamping block is adjusted, and the first clamping block rotates to drive a connecting rod to move; according to the device, the second clamping block is driven to slide, angle adjustment is facilitated, the clamping effect is improved. Meanwhile, in the adjusting process, the second clamping block slides under stress, the effect of better attaching to a patient is achieved, the fixing effect is improved, and the working precision is ensured.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a combined positioning frame device convenient for chest tumor radiotherapy. Background technique [0002] Radiation therapy for tumors (referred to as radiotherapy) is the use of radiation to treat cancer; radiation therapy has experienced more than a century of development history. After Roentgen discovered X-rays and Marie Curie discovered radium, they were soon used in clinical treatment of malignant tumors. Up to now, radiotherapy is still an important local treatment method for malignant tumors. About 70% of cancer patients need radiotherapy during the treatment of cancer, and about 40% of cancers can be cured by radiotherapy. [0003] The original angle that facilitates the positioning of chest tumor radiotherapy is accomplished by adjusting the posture of the bed and the patient. The adjustment process is more complicated.

AI Technical Summary

Problems solved by technology

[0003] The original angle that facilitates the positioning of chest tumor radiotherapy is accomplished by adjusting the posture of the bed and the patient. The adjustment process is relatively complicated. If the patient does not cooperate well, the positioning will be inaccurate. The alignment and positioning during the treatment process will be inaccurate, resulting in In order to treat incomplete treatment and inaccurate positioning, it will cause certain harm to the patient. During treatment, a fixation device is required to fix a specific part of the patient's body. However, the existing radiation therapy fixation device usually consists of a base and a bracket. However, the bracket usually cannot be adjusted in curvature to better adapt to the patient's fixation site, so that the best fixation effect cannot be achieved
