[0002] The gamma knife is a large medical device that integrates stereotactic technology and radiosurgery technology and is mainly used for treating craniocerebral diseases and body tumors. To improve the treatment accuracy of radiotherapy equipment, a positioning CT scan is required before gamma knife treatment. To ensure the correlation between the positioning CT scan and gamma knife treatment, a carbon fiber positioning bed needs to be adapted to the CT bed for CT scanning during the positioning CT scan. To maintain consistency, usually, the CT scan and the treatment bed share a set of carbon fiber positioning beds. Due to such usage scenarios, the carbon fiber positioning bed on the gamma knife treatment bed generally needs to be frequently disassembled and assembled, and frequent disassembly and assembly often bring the following problems: (1) inaccurate positioning, resulting in low treatment accuracy; (2) inconvenient installation method, time-consuming for disassembly and assembly.
