U-shaped beam three-dimensional movable positioning bed suitable for radiotherapy

Abstract

The invention relates to a U-shaped beam three-dimensional movable positioning bed suitable for radiotherapy and belongs to the manufacturing technical field of novel medical auxiliary equipment. The U-shaped beam three-dimensional movable positioning bed comprises the following 20 components: a base, a horizontal rotating servo motor, a U-shaped beam, a longitudinal swinging servo motor, a worm A, a worm gear A, a longitudinal swinging shaft, a longitudinal main beam, a transverse swinging shaft, a cross beam, a frame, a transverse swinging servo motor, a worm B, a worm gear B, a three-section type bed board, a rocker arm support, an electric lifting screw, a bed board hinge, constraint fixing belt, an intelligent controller and the like. During usage, the working power supply of the intelligent controller is switched on, and an operation track control program is preset according to the irradiation treatment requirements of a specific patient. After that, an operation switch is turned on. The program of the U-shaped beam three-dimensional movable positioning bed can be preset to realize the scanning motions of different tracks or realize the positioning operation on different irradiation parts. The U-shaped beam three-dimensional movable positioning bed has the advantages of being reasonable in design, compact in structure, convenient to use and the like.

Description

technical field [0001] The invention relates to a U-shaped beam three-dimensional mobile positioning bed suitable for radiotherapy, and belongs to the technical field of new medical auxiliary equipment manufacturing. Background technique [0002] Although various medical beds in current clinical applications can also be moved by the lower traveling wheels, or the use angles of different segments of the bed board can be adjusted by a mechanical lever mechanism, the structure is too simple to achieve in-situ horizontal rotation and longitudinal inclination. Large-scale changes, three-dimensional adjustment and positioning such as lateral swing of the bed surface, especially cannot intelligently control displacement according to a certain angle or motion trajectory, especially not suitable for regional scanning of a certain lesion area of ​​a patient during radiotherapy and according to a certain To move the patient on the trajectory and realize the scanning irradiation therapy...

[0002] Although various medical beds in current clinical applications can also be moved by the lower traveling wheels, or the use angles of different segments of the bed board can be adjusted by a mechanical lever mechanism, the structure is too simple to achieve in-situ horizontal rotation and longitudinal inclination. Large-scale changes, three-dimensional adjustment and positioning such as lateral swing of the bed surface, especially cannot intelligently control displacement according to a certain angle or motion trajectory, especially not suitable for regional scanning of a certain lesion area of ​​a patient during radiotherapy and according to a certain To move the patient on the trajectory and realize the scanning irradiation therapy, it is necessary to set the moving speed and irradiation intensity index according to the preset trajectory of the lesion area, so as to realize the precise positioning of the patient by the numerical control of the treatment bed and the scanning displacement therapy
