Abstract

The invention relates to a wrist joint recurrent movable external fixation bracket. The wrist joint recurrent movable external fixation bracket includes a near-end long bracket and a far-end short bracket, wherein the near-end long bracket comprises a near-end bracket rod and a near-end connection sleeve fixed to one end of the near-end bracket rod; 2 single nail clips which are clamped in slidingfit with the near-end bracket rod are arranged on the near-end bracket rod; the far-end short bracket includes a far-end bracket rod and a far-end connection sleeve fixed to one end of the far-end bracket rod; one double nail clip which is clamped in sliding fit with the far-end bracket rod is arranged on the far-end bracket rod; the near end connection sleeve of the near-end long bracket is connected with a universal ball joint; the far-end connection sleeve of the far-end short bracket is connected with a ball plane joint; and the near-end long bracket and the far-end short bracket are coordinatively connected through the universal ball joint and the ball plane joint. The wrist joint recurrent movable external fixation bracket enters dynamic fixing by loosening a second cam shaft and then unscrewing a hand wheel: the ball plane joint can perform fan sector movement within the controlled angle range, so that the wrist joint can perform the extension and flexion function exercise frequently.

Description

technical field [0001] The invention relates to a wrist joint frequently movable external fixation bracket, which belongs to the field of orthopedic medical instruments. Background technique [0002] For distal radius fractures, especially comminuted fractures that involve the articular surface, the disadvantage of manipulative reduction and external fixation with a plaster support is that it cannot provide support for the fracture end, the articular surface of the fracture end is prone to collapse, and the fracture is prone to malunion; During the fixation period, the wrist joint can move slightly, which is conducive to reducing and avoiding the occurrence of joint stiffness. [0003] The wrist joint movable bracket is an external fixation bracket used to assist the reduction and growth of the distal radius fracture. The distal radius fracture can be restored to the position before the fracture through external traction and reduction, and the wrist joint movable bracket is ...
