Abstract

The utility model discloses an acromioclavicular joint dislocation reduction device, which relates to the technical field of medical instruments and comprises a positioner, and the positioner comprises a positioning handle, a sliding positioning bent handle, a positioning rod and a locking column. An abutting end is arranged on the positioning bent handle; a guide cylinder is arranged on the positioning handle, and a first transmission part is arranged in the guide cylinder; the positioning rod is mounted in the guide cylinder, a guide channel is formed in the positioning rod, and a second transmission part is arranged on the positioning rod; a guide sleeve rod is arranged in the guide channel; by arranging the positioning cylinder and the positioning rod, under the locking action of the first transmission part and the second transmission part, acting force can be applied to the acromioclavicular joint by rotating the positioning rod, the acromioclavicular joint is reset after being connected in an abutting mode, and the acting force does not need to be continuously applied to the positioning rod manually; the guide sleeve rod is arranged on the drilling equipment and provides guidance for the drilling equipment, the drilling equipment is guided to drill holes in the acromioclavicular joint through the guide channel, then the guide sleeve rod penetrates through the established bone tunnel to provide guidance for the guide wire, and the guide wire can conveniently penetrate through the bone tunnel.
