origin：Hangzhou Zhengda Medical Co., Ltd. Time：2025-9-18 Hits：665
Our company recently received an invention patent from the State Intellectual Property Office for its "Four-Degree-of-Freedom Hip Passive Motion Rehabilitation Device," the result of two years of continuous research
and development and technological breakthroughs. Patent number: ZL2023-1-0946851.4.
In the intellectual property system, invention patents are highly valued for their rigorous examination standards. This patent is the culmination of the R&D team's continuous investment and dedication, as well as the
company's ongoing accumulation and exploration in the field of rehabilitation equipment.
This patent proposes a rehabilitation device capable of multi-directional passive motion simulation. Its core structure consists of a body, motion simulation components, and a control component. It utilizes
multi-axis electric actuators and a universal joint structure to simulate multi-degree-of-freedom motion in the hip joint. Combined with a leg fixation module, a rotation mechanism, and a strap design, the training process more closely aligns with the natural motion patterns of human joints, providing more scientific support for postoperative rehabilitation training.
Going forward, the company will continue to prioritize R&D and innovation, actively exploring technological innovations, and strive to provide users with higher-quality rehabilitation products and services.
