Abstract

The present invention provides a box structure, comprising: a drive assembly; an installation assembly connected to the drive assembly, including a blade box for installing blades and a connecting support connected to the blade box; a sliding assembly, including a guide rail and a sliding part slidably arranged on the guide rail, the sliding part is connected to the blade box, the drive assembly can drive the installation assembly to slide along the guide rail; and is connected to the connecting support The support assembly is slidably arranged on the guide rail, and abuts against the guide rail, so as to limit the movement of the blade box in a direction deviating from the guide rail. The support assembly can increase the contact area between the slider and the guide rail, so as to limit the movement of the vane box away from the direction of the guide rail, reduce the lateral turning of the vane box during the movement, ensure the movement accuracy of the vane box, and improve the multi- The precision of the leaf collimator. The invention also provides a multi-leaf collimator.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multi-leaf collimator and its box structure. Background technique [0002] During the movement of the MLC (Multi-leaf Collimator, multi-leaf collimator) leaf box on the mounting plate, it is hoped that it can move forward with high precision and smoothly to ensure the conformal accuracy of the multi-leaf collimator. However, due to the various requirements of design and installation space, the movement of the blade box can only be driven by the motor located on one side of the blade box, so that a lateral torque is inevitably generated, so that the end surface of the blade box and the guide rail are in the forward direction. Form a small angle, thereby affecting the accuracy of the movement of the leaf box, resulting in inaccurate conformal accuracy of the multi-leaf collimator, and affecting the treatment results of the radiotherapy equipment.
