Radiotherapy body frame lifting device and radiotherapy body frame

Abstract

The invention discloses a radiotherapy body frame lifting device and a radiotherapy body frame. The radiotherapy body frame lifting device includes a base, one end of the base is provided with two slots, and the other end is provided with two first sliding grooves. A first lift support rod is fixed in each slot; a second lift support rod is slidably connected to each chute; the heights of the first lift support rod and the second lift support rod are adjusted independently by the controller; the radiotherapy The body frame lifting device can not only adjust the height of the radiotherapy body frame, but also directly serve as the support frame of the radiotherapy body frame, which is simpler in structure; when the radiation therapy body frame lifting device is installed, the upper body pad can be placed around the lower body pad. The connecting piece of the board adjusts the pitch angle. The radiotherapy body frame is also provided with an adjustable grasping rod, a headrest, an arm-limiting belt and a gear post, which can not only accurately fix the body position, but also improve the comfort of the patient.

Description

technical field [0001] The invention relates to the technical field of radiotherapy body frames, in particular to a radiotherapy body frame lifting device and a radiotherapy body frame. Background technique [0002] Radiation therapy is a treatment method that irradiates tumors with rays of various energies to inhibit and kill cancer cells. The purpose of radiation therapy is to continuously improve the tumor by increasing the dose of the target area and / or reducing the radiation damage to normal tissues around the target area. The local control rate of the treatment further increases the survival rate and / or improves the quality of life. [0003] Compared with conventional radiotherapy, intensity-modulated radiation therapy technology has many advantages. As a result, it can achieve the maximum dose in the target area, the minimum exposure to normal tissues around the target area, more accurate positioning and irradiation of the target area, and the most uniform dose distri...

AI Technical Summary

Problems solved by technology

However, the existing body position fixation technology is easy to cause discomfort to patients, and the intensity-modulated radiation therapy usually takes a long time, which easily leads to involuntary body movement of patients during the treatment process, causing the movement of the tumor target area and organs at risk, making them deviate from the adjustment. Underdose of tumors or overdose of endangered organs outside the strong irradiation field

[0005] At present, when radiotherapy is performed on tumor patients clinically, the patient is mostly placed on a radiotherapy frame and irradiated with a medical linear accelerator. Most of the existing radiotherapy frames are manually adjusted by medical staff when the upper body is lifted and adjusted, and it is very difficult to Difficult to precisely adjust the inclination angle of the radiotherapy body frame according to actual needs

[0006] In addition, most of the existing radiotherapy body frames are too single-function, and there is no structure that can install auxiliary positioning devices. However, for breast cancer or thoracoabdominal and pelvic tumors, the arms need to be raised or tilted back. If the arms cannot be comfortably and Precise fixation, low repeatability of each positioning, and it is easy to cause involuntary movement of patients during treatment and affect the effect of radiotherapy
