Abstract

The present invention discloses a radiotherapy positioning bed. The radiotherapy positioning bed comprises a fixed frame; the front side of the fixed frame is provided with a bottom plate; the bottomplate is fixedly connected with the fixed frame; the top of the bottom plate is provided with a bed body; the bottom of the bed body is provided with a movable mechanism; the top of the bed body is provided with a fixed mechanism; the movable mechanism comprises a fixed plate; the fixed plate is arranged at the bottom of the bed body; the fixed plate is in sliding connection with the bed body; andthe bottom of the bed body is provided with a limiting groove. When a movable plate moves, the inclined bottom plate is lifted, so that the movable plate moves up and down, and then the bed body moves up and down; a gear ring fixed to the inner wall of a fixed barrel is arranged, and a gear rotates along the gear ring, so that the first fixed plate rotates, and then the bed body rotates; and a nut rotates, so that a screw rod drives the bed body to move, the bed body takes a patient to move towards a ray cross point, a nidus of the patient coincides with the ray cross point, and positioning of the nidus of the patient is realized.

Description

technical field [0001] The invention relates to the field of radiotherapy, in particular to a positioning bed for radiotherapy. Background technique [0002] Radiation therapy is the treatment of malignant tumors and some benign diseases by using one or more ionizing radiations. The means of radiation therapy is ionizing radiation. [0003] At present, the treatment couch is an important component of radiation therapy, but in actual use, the treatment couch cannot move in three dimensions. When positioning the patient's lesion, it is necessary to adjust the ray angle of the radiation head. Due to the large number of rays in the radiation head, it is difficult to adjust the positioning large and time consuming. [0004] Therefore, it is necessary to invent a radiotherapy positioning bed to solve the above problems. Contents of the invention [0005] The purpose of the present invention is to provide a radiotherapy positioning bed. When the movable plate moves, it will ris...
