A radiation-proof auxiliary guide bed for liver cancer radiotherapy

Abstract

The invention discloses a radiation-proof auxiliary guiding bed for liver cancer radiotherapy, which comprises a bottom plate, universal wheels, a lifting bracket, a lying board, a chest frame and a lifting console. The lower surface of the bottom board is provided with universal wheels for supporting walking, and the lying board passes through The vertically arranged lifting bracket is installed on the bottom plate. The chest frame is a door-shaped frame. The lower end of the chest frame is connected to a distance sensor arranged on the bottom plate. The frame rises and falls with the breathing of the patient, the lifting console is arranged on the bottom plate, and the lifting console is electrically connected with the lifting bracket and the distance sensor. The lifting support includes a lifting rod and a lifting seat. The upper end of the lifting rod is fixed to the lower surface of the lying board, the lower end of the lifting rod is inserted into the lifting seat, and the lifting seat is arranged on the upper surface of the bottom plate. The DC coil for lifting by the magnet is electrically connected with the lifting console.

Description

technical field [0001] The invention relates to the field of patient fixed beds, in particular to a radiation-proof auxiliary guide bed for liver cancer radiotherapy. Background technique [0002] Radiotherapy is a common treatment for cancer and tumors. During treatment, the patient needs to be placed on a hospital bed and then placed in the radiotherapy room. During radiotherapy, rays or proton beams are directed at the lesion to complete the destruction of harmful cells. [0003] During treatment, the emission position of the general radiotherapy rays can be adjusted so as to aim at the lesion. However, during the radiotherapy process, the lesion should not move, otherwise the accuracy of the radiation will be affected. Although the breathing and the patient's natural limb micro-movements can be controlled by the radiotherapy equipment However, this adjustment is not safe enough. When the movement range is large, there is still a greater possibility that the radiation and...

Problems solved by technology

[0003] During treatment, the emission position of the general radiotherapy rays can be adjusted to aim at the lesion. However, it is best not to move the lesion during the radiotherapy process, otherwise the accuracy of the radiation will be affected. Although the breathing and the patient's natural limb micro-movements can be controlled by the radiotherapy equipment The image recognition system recognizes and automatically adjusts the radiotherapy irradiation position. However, this adjustment is not safe enough. When the movement range is large, there is still a greater possibility that the radiation and protons will irradiate normal tissues near the target position and cause damage.

[0004] In the prior art, the adjustment of the orientation of the radiotherapy equipment itself is generally used to adapt to the slight changes in the position of the lesion, or to ensure the complete elimination of tumor cells by increasing the range of action. However, the prior art does not start from the hospital bed. Autonomous micro-body movements and breathing movements can automatically adjust the position of the lesion by adjusting the hospital bed, reducing the offset range and quickly resetting after the disturbance is eliminated. If there is a guide bed to realize such automatic position adjustment, it will not only reduce the radiotherapy radiation. damage, and more accurate healing
