  • Patent number: 11779373
    Abstract: A wearable robot for integrated fracture reduction and rehabilitation, comprising a proximal ring, a distal ring, six driving branch chains, motor driving device and manual driving device; the six driving branch chains are divided into two groups, each of them comprises a platform connecting sleeve, a sliding bearing, a bearing locking nut, a proximal Hooke hinge, an intermediate prismatic pair, a sleeve, a force sensor, and a distal Hooke hinge; one end of the driving branch chain is connected with the proximal ring by a connecting sleeve fastener, and the other end is connected with the distal ring by nut, each driving branch chain is connected with the driving devices via D-shaped shaft sleeve. The wearable robot has electric-manual dual model driving, and the branch chain can be quickly replaced during and after the operation.

  • Patent number: 8839690
    Abstract: A parallel mechanism with three-dimensional translation and one-dimensional rotation include a fixing rack, a mobile platform and four chains of the same structure which are symmetrically set between the fixing rack and the mobile platform. Each chain has a near rack rod and two parallel far rack rods. The mobile platform includes a main platform and an assistant platform connected by a revolute joint and perpendicular to each other. Each end of the main platform and the assistant platform is connected with a corresponding lower connecting shaft separately.
