Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy positioning, in particular to a rotary radiotherapy positioning frame. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. Radiation includes α, β, γ rays produced by radioisotopes 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 during the treatment of cancer, and about 40% of cancers can be cured by radiotherapy. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent, and it has become one of the main means of treating malignant tumors.

[0003] Although radiotherapy has only a few decades of history, it has developed rapidly. With the help of CT imaging technology and computer technology, radiotherapy technology has developed from two-dimensional radiotherapy to three-dimensional radiotherapy and four-dimensional radiotherapy technology. Radiotherapy dose distribution has also developed from point dose to volume dose distribution, and dose intensity modulation in volume dose distribution. The current mainstream radiotherapy technologies include stereotactic radiotherapy (SRT) and stereotactic radiosurgery (SRS). Stereotactic radiotherapy (SRT) includes three-dimensional conformal radiotherapy (3DCRT) and three-dimensional conformal intensity modulated radiotherapy (IMRT); stereotactic radiosurgery (SRS) includes X-knife, Gamma Knife (Y-knife) and Cyber ​​Knife. X-knife, Gamma Knife and Cyber ​​Knife are all within the scope of stereotactic radiotherapy, which is characterized by three-dimensional, small field, clustered, fractionated, and high-dose irradiation. It requires higher positioning accuracy and faster dose attenuation outside the target area.

[0004] A radiotherapy positioning frame disclosed in the Chinese utility model patent application disclosure specification CN220193838U, although the position of the positioning frame can be changed by a pulley, and the height of the positioning frame can be changed by adjusting the support column B, the adjusting screw, and the support column C, so that it can be suitable for different patients, and through a table lamp and a puzzle board, it can be accurately positioned before radiotherapy and play a protective role during radiotherapy, but the device also needs to be used next to the radiotherapy bed, and when the radiotherapy bed is moved, the position of the device needs to be adjusted manually, and the device is relatively simple and not very practical, so a utility model is proposed to solve the above problems.
