The utility model discloses adjustable linkage anti-inversion limiting hip external rotation orthopedic shoe cover, including first shoe cover, second shoe cover, two groups of clamping devices, restraint belt and two connecting devices, wherein, first shoe cover and second shoe cover are set up respectively corresponding patient left and right foot, and two groups of symmetrical clamping devices are fixedly arranged respectively in the lateral end of first shoe cover and second shoe cover, and each group of clamping devices includes a plurality of insertion holes along the longitudinal arrangement of shoe cover and the clamping assembly that cooperates with insertion hole, and the clamping assembly is slidably arranged above insertion hole, and two connecting devices all include connecting head and connecting assembly, wherein, one end of connecting assembly is fixedly connected with connecting head, and the other end can selectively insert any insertion hole and form the clamping fixed with corresponding clamping assembly. Therefore, through double shoe cover clamping linkage structure and adjustable restraint belt, the coherent mechanical constraint system from foot to lower limb is formed, and the collaborative correction to foot inversion and hip external rotation is realized.

The utility model discloses a kind of intraoperative adjustable knee joint surgery guiding device, it is related to medical instrument technical field, and it include: tibia guide plate, femur front guide plate, femur distal guide plate, four-in-one rotary adjusting plate, metal handle, four-in-one osteotomy plate, wherein four-in-one osteotomy plate is fixed on femur by screw thread nail hole, and bone cutting is carried out to femur by four-in-one osteotomy slot on four-in-one osteotomy plate of swing saw;The guiding device can realize femur valgus angle intraoperative real-time adjustment, realize femur external rotation angle intraoperative real-time adjustment, and more realize flexion-extension gap balance based on ligament judgment basis of operator.

The present application belongs to the field of exoskeleton robots, and particularly relates to a carrying exoskeleton robot with waist-hip integrated assisting motors and a control method thereof. The exoskeleton robot comprises an adjustable back frame mechanism, two groups of passive upper limb assisting mechanisms, two groups of waist-hip assisting mechanisms with double motors, the passive upper limb mechanisms are symmetrically arranged on both sides of the back frame mechanism, the passive upper limb mechanism comprises a shoulder joint forward flexion / extension mechanism, a shoulder joint internal rotation / external rotation mechanism and a bandage mechanism, a waist adjusting mechanism is connected with the waist-hip double assisting motor mechanism, and human carrying movement is coordinated with hip joint and lumbar vertebra movement. The present application adopts waist-hip double motor assistance, the waist motor provides assistance for relative rotation of the upper limb and the waist, and the hip motor provides assistance for relative rotation of the hip joint and walking, so as to adapt to different human carrying habits and solve the walking assistance problem.

The application discloses a six-degree-of-freedom light high-compatibility foot-ankle rehabilitation exoskeleton, which comprises an ankle-tibia connecting rod module, an ankle joint shaft module, a forefoot fixing module and a hindfoot fixing module; the ankle-tibia connecting rod module is used for being fixed in parallel with a lower leg and providing a power assisting anchor point at the back side of the lower leg; the forefoot fixing module and the hindfoot fixing module are respectively used for being fixed with the front end and the rear end of the foot of a wearer and providing an end power assisting anchor point at the heel; the ankle joint elastic element is directly contacted with the shoes of a user, and six-degree-of-freedom flexible interaction force is generated. The traditional foot-ankle exoskeleton is limited to toe flexion and dorsiflexion movement, and the elastic element design of the application can adapt to any movement of the foot-ankle within a safety limit, that is, the movement of the foot-ankle, such as internal rotation, external rotation, internal collection, external expansion, toe flexion and dorsiflexion. The application can effectively increase the activity of the foot-ankle, greatly improve the man-machine compatibility, and solve the problem that the existing ankle exoskeleton robot cannot meet the daily functional requirements of patients due to the heavy body configuration and single degree-of-freedom configuration.
