Anti-radiation auxiliary guide bed for liver cancer radiotherapy

Abstract

The invention discloses an anti-radiation auxiliary guide bed for liver cancer radiotherapy. The bed comprises a bottom plate, universal wheels, a lifting support, a lying plate, a chest frame and a lifting console. The universal wheels are arranged on the lower surface of the bottom plate and used for supporting walking. The lying plate is installed on the bottom plate through the vertically-arranged lifting support. The chest frame is a door-shaped frame, the lower end of the chest frame is connected with a distance sensor arranged on the bottom plate, the door-shaped top of the chest frameis attached to the chest of a patient lying on the lying plate, the chest frame fluctuates along with breathing of the patient, and the lifting console is arranged on the bottom plate and electricallyconnected with the lifting support and the distance sensor. The lifting support comprises a lifting rod and a lifting base, the upper end of the lifting rod is fixed to the lower surface of the lyingplate, the lower end of the lifting rod is inserted into the lifting base, the lifting base is arranged on the upper surface of the bottom plate, a permanent magnet is arranged on the lower end of the lifting rod, and a direct-current coil for driving the permanent magnet to ascend and descend is arranged in the lifting base and 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.
