Development of Intelligent Setting System for Fracture Based on X-Ray Image
In order to achieve micro-wound, intelligence and high efficiency for fracture setting, intelligent setting system for fracture is proposed in accordance with biomechanics and fracture therapy theory. In the comprehensive medical system based on C-shape-arm Xmachine, image processing and analysis is the core, programmable logical controller and stepping motor are important driving parts controlling mechanical parts. Six degree of freedom dynamics sensor ensures to control accurately force and moment. On the foundation of analyzing X-ray image peculiarities, method of processing and analysis is put forward, combining time domain with frequency domain. After mining domain knowledge in depth, setting actions is quantized into three non-continuous steps and is parameterized into two angles and one distance aiming at femoral-neck fracture. Objective features are extracted by virtue of three power polymerization curved surface fitting. Master-slave reference frame is advanced to solve a question that basic standard for parameters calculation is difficult to be determined. At the same time, four-group-sixteenframe algorithm is put forward to solve a probleM that the load value is unable to be calculated and applied precisely in the process of treatment of delayed union and non-union of fracture. Clinic experience proved that the system can help orthopedist to correctly and reliably complete fracture setting. And the system has many advantages such as micro-wound, low medical cost and low infection ratio, in comparison with traditional operation setting and manipulator setting.
