摘　　要：手术电钻是一种重要的耳科手术设备,可能会磨穿颅骨,对患者造成损伤;设计了一种用于手术电钻的智能监控装置,使用了电流传感器、电压传感器、转速传感器和压力传感器,通过信息融合技术识别手术电钻的工作状态、防止钻头磨穿骨质;智能监控装置的软件识别系统由卡尔曼滤波、差分运算和BP神经网络构成,能够实现高精度的识别。经测试,软件系统可以识别出80%的异常状态。Otologic drill is an important otologic surgical instrument. The otologic drill is likely to drill through the bone wall and damage the patient. An intelligent control device has been designed to prevent drilling through the bone wall. The intelligent control device where is installed current sensor, voltage sensor, speed sensor and pressure sensor uses information fusion technique. By using Kalman filter, difference algorithm and BP neural network, the software system can recognize abnormal operation of the drill precisely. Experiment results prove that the recognition accuracy of the system is better than 80%.
