市售的膝上截肢者使用的膝上假肢由弹簧和阻尼器组成，限制了股骨截肢者的日常运动，例如上楼梯。我们提出了一种新颖的装置，可以连接到多轴或单轴假肢上，并根据用户的需要进行主动操纵。#8217的动作。本研究的目的是开发一种可附加的控制单元，并通过楼梯上升测试评估来确认系统的基本功能。采用四连杆机构，无需精确调整假肢膝关节和装置的旋转轴即可操作装置。此外，通过设计弹簧操作的死点预防机构和可自由移动的大腿固定部分，可以避免系统的死点。在爬楼梯实验中，我们确认使用该系统，受试者可以作为一个健全的人爬上楼梯。总之，我们开发了一种可附加的控制单元，可以附加到多轴或单轴假肢上，并根据用户的需求进行主动操纵。的动作，并确认可附加的控制单元有助于困难的动作。
Commercially available above-knee prosthetic legs prescribed to above-knee amputees are composed of springs and dampers, which restrict the daily movements of transfemoral amputees, such as stair ascent. We propose a novel device that can be attached to multi-or single-axis prosthetic legs and maneuvered actively according to the user&# 8217; s movements. The objective of this study was to develop an attachable cybernic unit and to confirm the basic capability of the system by evaluation with a stair ascent test. Using a four-linkage mechanism, the device can be operated without precise adjustment of the rotation axes of the prosthetic knee and the device. In addition, the dead point of the system can be avoided by designing a spring-operated dead point prevention mechanism and a thigh-fixing part with freedom of movement. In the stair ascent experiment, we confirmed that using the system, the subject ascended the steps as an able-bodied person. In conclusion, we developed an attachable cybernic unit that can be attached to multi-or single-axis prosthetic legs and maneuvered actively according to the user&# 8217; s movements, and confirmed that the attachable cybernic unit facilitates difficult movements.
