Abstract

We report the use of a bone-anchored, self-contained robotic arm with both sensory and motor components over 3 to 7 years in four patients after transhumeral amputation. The implant allowed for bidirectional communication between a prosthetic hand and electrodes implanted in the nerves and muscles of the upper arm and was anchored to the humerus through osseointegration, the process in which bone cells attach to an artificial surface without formation of fibrous tissue. Use of the device did not require formal training and depended on the intuitive intent of the user to activate movement and sensory feedback from the prosthesis. Daily use resulted in increasing sensory acuity and effectiveness in work and other activities of daily life. (Funded by the Promobilia Foundation and others.).

摘要

我们报告了在 4 名肱骨截肢患者中使用骨内固定、自给自足的机器人手臂，该手臂具有感觉和运动组件，使用时间为 3 至 7 年。该植入物允许假肢手与植入在上臂神经和肌肉中的电极之间进行双向通信，并通过骨整合固定到肱骨上，骨整合是指骨细胞附着在人工表面上而不形成纤维组织的过程。使用该设备不需要正式培训，而取决于用户激活运动的直观意图和来自假肢的感觉反馈。日常使用可提高感官敏锐度，并提高工作和日常生活活动的效率。（由 Promobilia 基金会等资助）。
