背景和目标：DEKA集成解决方案公司（DEKA）受美国国防部高级研究计划局委托设计了一种假肢系统，与现有的最先进的假肢系统相比，该假肢系统将是一个巨大的改进。本文的目的是描述两个DEKA手臂原型（Gen 2和Gen 3）用于退伍军人事务部研究，以优化DEKA臂。技术：本文报告了Gen 2和Gen 3原型的特征和功能，讨论了重量、外观、握把、动力运动端点、假肢控制、假肢医生界面、电源、用户通知、故障排除和专用承窝特征;讨论：DEKA机械臂有三种配置：桡骨配置、肱骨配置和肩关节配置。所有配置都有六个预编程的抓地力模式和四个手腕运动。肱骨配置有四个动力肘运动。肩部配置使用端点控制来执行同时的多关节运动。三种版本的脚踏开关用作输入。Gen 3包含了主要的设计变化，包括一个复合腕关节，它将桡偏与腕关节屈曲和尺骨偏与腕关节伸展结合在一起，一个用于肱骨配置和肩部配置的内部电池，以及嵌入式腕关节显示器。临床相关性DEKA机械臂是一种先进的上肢假肢，尚未投入商业使用。它的功能超过了目前可用的技术。本手稿描述了DEKA机械臂的两个原型（Gen 2和Gen 3）的特征和功能。
Background and aim: DEKA Integrated Solutions Corp. (DEKA) was charged by the Defense Advanced Research Project Agency to design a prosthetic arm system that would be a dramatic improvement compared with the existing state of the art. The purpose of this article is to describe the two DEKA Arm prototypes (Gen 2 and Gen 3) used in the Veterans Affairs Study to optimize the DEKA Arm.Technique: This article reports on the features and functionality of the Gen 2 and Gen 3 prototypes discussing weight, cosmesis, grips, powered movements Endpoint, prosthetic controls, prosthetist interface, power sources, user notifications, troubleshooting, and specialized socket features; pointing out changes made during the optimization efforts.Discussion: The DEKA Arm is available in three configurations: radial configuration, humeral configuration, and shoulder configuration. All configurations have six preprogrammed grip patterns and four wrist movements. The humeral configuration has four powered elbow movements. The shoulder configuration uses Endpoint Control to perform simultaneous multi-joint movements. Three versions of foot controls were used as inputs. The Gen 3 incorporated major design changes, including a compound wrist that combined radial deviation with wrist flexion and ulnar deviation with wrist extension, an internal battery for the humeral configuration and shoulder configuration, and embedded wrist display.Clinical relevance The DEKA Arm is an advanced upper limb prosthesis, not yet available for commercial use. It has functionality that surpasses currently available technology. This manuscript describes the features and functionality of two prototypes of the DEKA Arm, the Gen 2 and the Gen 3.
