Radiotherapy robot treatment bed of SCARA structure

Abstract

The invention discloses a robot treatment bed for radiotherapy with a SCARA structure, which includes a lifting device, a first horizontal rotating arm connected to the lifting device, a second horizontal rotating arm connected to the first horizontal rotating arm, and a first horizontal rotating arm connected to the first horizontal rotating arm. The combined rotary joint connected with the two horizontal rotary arms, and the bed board connected with the above-mentioned combined rotary joint; the lifting device can control the bed board to move along the Z-axis direction, and the first horizontal rotary arm and the second horizontal rotary arm cooperate to control the bed board in the X-axis The combined rotary joint can control the bed board to rotate around the X-axis, Y-axis and Z-axis respectively, thus, the bed board can move in any direction and rotate in any direction in the treatment area, so as to realize Efficient and precise radiation therapy; and the structure is simple and reasonable, without occupying a large 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
