The purpose of this article is to develop a new concept of modular and operative prosthetic hand based on rapid prototyping and a novel shape-memory-alloy (SMA) actuator, thus minimizing the manufacturing costs. An underactuated mechanism was needed for the design of the prosthesis to use only one input source. Taking into account the state of the art, an underactuated mechanism prosthetic hand was chosen so as to implement the modifications required for including the external SMA actuator. A modular design of a new prosthesis was developed which incorporated a novel SMA actuator for the index finger movement. The primary objective of the prosthesis is achieved, obtaining a modular and functional low-cost prosthesis based on additive manufacturing executed by a novel SMA actuator. The external SMA actuator provides a modular system which allows implementing it in different systems. This paper combines rapid prototyping and a novel SMA actuator to develop a new concept of modular and operative low-cost prosthetic hand.
本文的目的是基于快速成型技术和新型形状记忆合金（SMA）驱动器开发一种模块化手术假肢手的新概念，从而将制造成本降至最低。假肢设计需要一种欠驱动机构，以便仅使用一个输入源。考虑到当前技术水平，选择了一种欠驱动机构假肢手，以便实施纳入外部SMA驱动器所需的修改。开发了一种新型假肢的模块化设计，该设计包含用于食指运动的新型SMA驱动器。假肢的主要目标得以实现，即基于由新型SMA驱动器执行的增材制造获得一种模块化且功能齐全的低成本假肢。外部SMA驱动器提供了一个模块化系统，使其能够在不同系统中实施。本文结合快速成型技术和新型SMA驱动器，开发了一种模块化手术低成本假肢手的新概念。
