Active movable fixing mount for orthopaedic postoperative rehabilitation

Abstract

The invention relates to an active movable fixing mount for orthopaedic postoperative rehabilitation, comprising an upper fixing ring and a lower fixing ring, wherein each quarter ring corresponding to the upper fixing ring is hollowed out with a sliding rail, a lower fixing ring is provided with four first spherical hinges, a slider is arranged in each of the four hollowed-out sliding rails, a lower end face of the slider is provide with a second spherical hinge, the first spherical hinge and the second spherical hinge are connected through a sliding rod; the a sliding rod includes an inner rod and a sleeve rod; at the bottom of the innner rod and at the top of the sleeve rod, the first spherical hinge and the second spherical hinge are respectively provided with a threaded thin shaft, the threaded hole at the bottom of the inner rod is connected with a threaded thin shaft of the first spherical hinge, the threaded hole at the top of the sleeve rod is connected with the threaded thinshaft of the second spherical hinge, the side walls of the concave groove on both sides of the sliding rail are provided with fine tooth patterns, and the slider comprises two limiting plates, a rotating shaft, a tooth ring, and the limiting plate are connected through the rotating shaft, and the tooth ring is arranged on the rotating shaft, and the tooth ring is consistent with the fine tooth patterns of the side walls of the concave groove.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a movable fixing frame for active orthopedic postoperative rehabilitation. Background technique [0002] In recent years, orthopedic fixation devices have developed rapidly, and a variety of fracture correction devices have appeared during rehabilitation. For example, the universal adjustable fracture external fixator designed by those skilled in the art can adjust the position and direction of the fixation nail holes arbitrarily, so that the distance and direction of drilling holes in the operation are no longer strictly limited by the fixator, thereby reducing the operation Difficult, but the translation and rotation of the device must be operated separately, and the accuracy is low. Other three-dimensional external fixation frames, such as Irizanov frame and Basini's frame, also cannot satisfy all the translation and rotation movements required for fracture reduction at the same t...
