Device for installing image guidance radiotherapy device detection screen

Abstract

The invention provides a device for installing an image guidance radiotherapy device detection screen, and belongs to the technical field of auxiliary medical instruments. The device comprises a lifting mechanism arranged on the left side of the device and used for driving the device to ascend and descend vertically, a telescopic mechanism arranged on the upper side of the device and used for driving the device to conduct telescopic motion forwards and backwards, and a folding mechanism arranged on the rear side of the device and used for driving the device to be unfolded and folded. The lifting mechanism comprises a first motor, a first coupler, a first lead screw, a first lead screw sliding nut, a first lead screw sliding nut seat and the like. The telescopic device comprises a third motor, a third coupler, a third lead screw, a third lead screw sliding nut, a third lead screw sliding nut seat and the like. The folding device comprises a second motor, a second coupler, a second lead screw, a second lead screw sliding nut, a second lead screw sliding nut seat and the like. In the using process, the ascent and descent motion, the telescopic motion and the folding motion are independent.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical devices, in particular to a device for installing a detection screen of an image-guided radiotherapy device. Background technique [0002] The design of the mechanism for installing the detection screen of the image-guided radiotherapy device is rarely mentioned in the current published literature. It can be seen from the published images that there are mainly two mechanisms for installing the detection screen of the image-guided radiotherapy device: three-joint secondary Telescopic arm device and detection screen telescopic mechanism device. [0003] The three-joint secondary telescopic arm device is mainly developed and produced by Varian in the United States. "Tsinghua University Medical IGRT Accelerator Development and Industrialization Planning Background" introduced that the three-joint secondary telescopic arm adopts the design method of simulating the human arm joints, and has f...

AI Technical Summary

Problems solved by technology

"Tsinghua University Medical IGRT Accelerator Development and Industrialization Planning Background" introduced that the three-joint secondary telescopic arm adopts the design method of simulating the human arm joints, and has four degrees of freedom. The advantage of this mechanical arm is that it can drive the digital detection screen to achieve flexibility. Fast movement, the disadvantage is that the range of movement of the telescopic arm is small, the performance requirements for the motor and other equipment are high, and the cost is expensive

"KV / MV Homologous Double-beam Medical Electron Linear Accelerator Prototype Development" introduces that the telescopic mechanism device of the detection screen is jointly developed by Tsinghua University and Nuctech. It is mainly completed by a telescopic mechanism. The three actions of folding are not independent of each other
