Positioning frame for thoracic tumor radiotherapy conveniently

Abstract

The invention discloses a positioning frame for thoracic tumor radiotherapy conveniently, which comprises a bottom plate. A first baffle is welded at the left side of the top of the bottom plate; a second baffle is welded at the right side of the top of the bottom plate; a first electric pushing rod is fixedly arranged on the surface of the first baffle; a second electric pushing rod is fixedly arranged on the surface of the second baffle; one end, far away from the first baffle, of the first electric pushing rod is fixedly connected with a first positioning plate; one end, far away from the second baffle, of the second electric pushing rod is fixedly connected with a second positioning plate; a first electronic ruler is arranged between the first baffle and the first positioning plate; and a second electronic ruler is arranged between the second baffle and the second positioning plate. Through match among the first electric pushing rod, the second electric pushing rod, the first electronic ruler, the second electronic ruler, a pressure sensor and a PLC, the problems that the existing tumor radiotherapy positioning frame is not automatic enough as manual adjustment is adopted, andthe positioning accuracy is influenced can be solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a convenient positioning frame for chest tumor radiotherapy. Background technique [0002] At present, in tumor radiotherapy, radiologists need to fix the patient's body position to ensure the accuracy of treatment. In chest radiotherapy for lung cancer, esophageal cancer, and pleural cancer, it is necessary to fix the patient's chest body mask. [0003] Existing body position fixing frame adopts the bracket form, and comprises chest fixing frame body, is arranged on the body mask fixing slot at the four corners of chest fixing frame body and is positioned at the scale bar of chest fixing frame body both sides. The body mask fixing slot is used for connecting the chest body mask covering the human body, and can adjust the width of the body mask. However, since the device does not fix the head and does not have a specific reference object, although the patient maintains...
