One of major challenges in bone cutting surgery is replacing the cutting tool at the right time. This paper develops a burr wear detection method through analyzing the acceleration signal of the operation power device. Wavelet packet decomposition is used to separate the noise and the harmonic whose frequency is an integer times of the spindle frequency of the operation power device. The energy ratio...
In this paper, we study on the cooperation of the virtual digital surgery design technology, three-dimensional navigation and high-precision robot, aiming to implement the preoperative design content more accurately. In this system, virtual digital surgery design acts as the “brain” to provide position and motion information. Three-dimensional navigation system can carry out tasks such as registering...
In order to enhance operation safety, this study analyzes the sound pressure signal obtained from the bone drilling process for condition monitoring. The drilling sound is caused by the contact between the drill bit and the bone, and we only pay attention to the harmonic components of the sound pressure signal whose frequencies are integer multiples of spindle frequency. Lifting wavelet transform...
