Lower limb fracture reduction device

Abstract

The invention provides a lower limb fracture reduction device. The lower limb fracture reduction device comprises a hip part, a thigh part, a knee joint, a shank part and an ankle part, wherein the hip part has three degrees of freedom including retracting / stretching of a coronal position, antexion / rear protraction of a sagittal plane and rotation separately; the thigh part has degree of freedom of stretching / pushing; the knee joint has degree of freedom of flexion and extension of the sagittal plane; the shank part has degree of freedom of stretching / pushing; the ankle part has two degrees of freedom including degree of freedom of flexion and extension of the sagittal plane of the ankle part and rotation separately; and the various degrees of freedom are sensed by a sensor to guarantee accurate exercise and then guarantee safety of human tissues. The lower limb fracture reduction device has movement functions corresponding to the lower limbs of a human body, reduction and temporary fixation of fracture are realized by movement of various parts of the lower limbs; and therefore, the lower limb fracture reduction device has the advantages of accurate reduction, good safety and high degree of automation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lower limb fracture reduction device. Background technique [0002] Most of the lower extremity fracture reduction techniques in clinical application currently rely on manpower and hand-held instruments for incision and direct vision reduction. Although some studies use mechanical reduction devices, they are basically completed by manual traction equipment. Because the form fails to combine the physiological activities and functions of each joint, it cannot achieve a good reset effect. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention proposes a lower limb fracture reduction device with precise reduction, good safety and high degree of automation. [0004] In order to achieve the above object, the present invention proposes a lower limb fracture reduction device, which includes a fixing frame (1) for in...
