Radiotherapy robot treatment bed of SCARA structure

Abstract

The invention discloses a radiotherapy robot treatment bed of an SCARA structure, which includes a lifting device, a first horizontal rotating arm connected with the lifting device, a second horizontal rotating arm connected with the first horizontal rotating arm, a combined rotating joint connected with the second horizontal rotating arm, and a bed plate connected with the combined rotating joint. The lifting device can make the bed plate move along the Z axis. The first horizontal rotating arm and the second horizontal rotating arm work together to make the bed plate move in a plane where the X axis and the Y axis are located. The combined rotating joint can make the bed plate rotate about the X axis, the Y axis and the Z axis respectively. Thus, the bed plate can move in any direction and rotate in any direction in the treatment area, and efficient and precise radiotherapy can be realized. Moreover, the radiotherapy robot treatment bed has a simple and reasonable structure, and doesnot need to occupy a lot of space.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a robot treatment couch for radiotherapy with a SCARA (Selective Compliance Assembly Robot Arm, Chinese translation: Selective Compliance Assembly Robot Arm) structure. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioactive isotopes and x-rays, electron beams, proton beams and other particle beams produced by various x-ray therapy machines or accelerators. About 70% of cancer patients need radiotherapy in the course of cancer treatment, and about 40% of cancers can be cured with radiotherapy. The role and status of radiotherapy in tumor treatment has become increasingly prominent, and it has become one of the main means of treating malignant tumors. [0003] The treatment bed is one of the key equipments of radiotherapy. The preparation process...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the treatment beds used in radiation therapy are installed with a three-dimensional translation mechanism under the bed board and a circular motion to realize the movement and positioning of the bed board. This type of radiation therapy bed has limited posture adjustment and installation space, making it difficult to Achieve efficient and precise radiation therapy
