Automatic chair for treating cancers at heads and necks by using protons and heavy ions

Abstract

The present invention relates to an automatic chair for treating cancers at heads and necks by using protons and heavy ions and belongs to the medical apparatus and instrument field. The automatic chair comprises a six-degree-of-freedom parallel platform, a mounting plate, a three-dimensional translation platform and a chair; the mounting plate is square; the three-dimensional translation platform is fixed on the upper platform of the six-degree-of-freedom parallel platform through the mounting plate; and the chair includes a backrest, armrests, a seat and a footrest, wherein the seat is fixed on the three-dimensional translation platform by bolts. According to the automatic chair of the invention, the three-dimensional translation platform is adopted, so that the motion range of the automatic chair can be extended, and the problem of the stroke range coupling of various directions of an automatic chair using a six-degree-of-freedom parallel platform scheme can be solved.

Description

technical field [0001] The invention relates to an automatic chair for treating head and neck cancer with protons and heavy ions, and relates to the field of medical devices. Background technique [0002] The structure of the head and neck of the human body is very complex. In order to better avoid sensitive tissues and organs, the best treatment position is sitting. Due to weight constraints, the exits of the beam terminals of proton and heavy ion therapy equipment are fixed and non-adjustable. When protons and heavy ions are used to treat head and neck cancer, the conventional method is to move the patient on the seat in six dimensions (translation of X, Y, Z) through a six-degree-of-freedom serial robot arm or a six-degree-of-freedom parallel platform. and rotation around X, Y, Z) to achieve the purpose of precisely aligning the tumor to the center of the treatment beam. [0003] Compared with the six-degree-of-freedom serial manipulator, the six-degree-of-freedom paral...

AI Technical Summary

Problems solved by technology

This has caused the problem that the size of the automatic chair based on the six-degree-of-freedom parallel platform is relatively large

[0005] There are usually a lot of equipment installed in the treatment room of the hospital, and the space is limited. It is not realistic to greatly increase the size of the parallel six-degree-of-freedom platform
