描述(由申请人提供)：每年有超过6100名美国人接受 上肢截肢需要使用假肢装置。使用当前 设备，病人不能机械和电气控制 模仿正常功能的假肢。当神经被切断或被破坏时， 关于控制的信息仍然存在。更好、更自然地控制 如果这些信息可以用来操作假肢，就可以实现假体 假肢。到目前为止，在电子设备之间没有稳定、可靠的接口 假体和神经系统是存在的。此外，软组织， 压配合到树桩的附件不太理想。骨性附着 该装置将极大地方便机械控制和实用。初级阶段 该项目的目标是证明骨骼的可行性 可同时实现机械和电气控制的附加接口。一个 已开发出周围神经接口，其中肌肉滑块 从记录电极环境中的宿主肌肉中分离出来。一个 已开发出经皮口/骨联合附着器 具有表面微纹理，允许稳定的皮肤连接，连接性 组织和骨骼到它的表面。拟议中的实验旨在 验证系统的两个部分的各个方面，使其具有实用价值。

DESCRIPTION (Provided by Applicant): Each year over 6,100 Americans undergo upper limb amputation requiring the use of prosthetic devices. With current devices, the patient is unable to mechanically and electrically control the prosthetic to mimic normal function. When nerves are severed or disrupted, the information for control is still present. A better, more natural control of the prosthesis could be achieved if that information could be used to operate a prosthesis. To-date, no stable, reliable interface between the electronics of the prosthesis and the nervous system exists. Additionally, soft tissue, press-fit attachment to the stump is less than ideal. Skeletal attachment of the device would greatly facilitate mechanical control and utility. The primary objective of this project is to demonstrate the feasibility of a skeletally attached interface that can effect both mechanical and electrical control. A peripheral nerve interface has been developed in which slips of muscle are isolated from a host muscle in the environment of a recording electrode. A combined transcutaneous port/skeletal attachment device, has been developed with surface microtexturing that allow a stable connection of skin, connective tissues and bone to its surface. The proposed experiments are designed to validate aspects of both parts of the system, leading to its practical utility.
