The use of a bone-anchored device to transmit electrical signals from internalized muscle electrodes was studied in a sheep model. The bone-anchored device was used as a conduit for the passage of a wire connecting an internal epimysial electrode to an external signal-recording device. The bone-anchored device was inserted into an intact tibia and the electrode attached to the adjacent M. peroneus tertius. "Physiological" signals with low signal-to-noise ratios were successfully obtained over a 12-week period by walking the sheep on a treadmill. Reliable transmission of multiple muscle signals across the skin barrier is essential for providing intuitive, biomimetic upper limb prostheses. This technology has the potential to provide a better functional and reliable solution for upper limb amputee rehabilitation: attachment and control.
我们在绵羊模型中研究了将电信号从内置肌肉电极通过骨锚设备传输的方法。该骨锚设备被用作将内部肌外膜电极与外部信号记录设备连接的导线的通道。将骨锚设备插入完整的胫骨中,并将电极附着在相邻的第三腓骨肌上。通过让绵羊在跑步机上行走,我们成功地在 12 周的时间内获得了具有低信噪比的“生理”信号。可靠地穿过皮肤屏障传输多个肌肉信号对于提供直观、仿生的上肢假肢至关重要。这项技术有可能为上肢截肢者的康复提供更好的功能和可靠的解决方案:附着和控制。
