Abstract

The invention discloses a calcaneus orthopaedics ring bar combined external fixation support comprising an upper ring piece and a lower ring piece connected with the upper ring piece through a fixing member; two ends of the upper and lower ring pieces are respectively provided with a plurality of screw holes; the screw hole is provided with a needle clamp cover; the bottom of the needle clamp cover is provided with a plurality of needle slots; a bone spicule is arranged in each needle slot. The upper and lower ring pieces are interlaced so as to adapt to relative angle and position changes of fracture bone spicule fixation, thus positioning the calcaneus bone blocks in different directions, lengths and angles; the calcaneus orthopaedics ring bar combined external fixation support is simple in structure, and convenient in adjusting.

Description

technical field [0001] The invention relates to a calcaneus orthopedic ring-rod combined external fixation bracket. Background technique [0002] Calcaneal fractures, especially severely comminuted fractures, are mostly accompanied by upward and downward displacement or angular dislocation of the bones, requiring clinicians to perform anatomical reduction of the parts during the operation, which requires professional orthopedic instruments to fix the reduced bones , to help bones recover and heal as soon as possible, the orthopedic ring rod combined external fixation bracket is one of the commonly used medical devices in orthopedic clinics. [0003] At present, most of the orthopedic ring-rod combination external fixation brackets commonly used in the market are connected by a straight main body between two clamping blocks, and generally have the following disadvantages: 1. The distribution of bone needles is generally straight or vertically fixed; 2. The straight-going sub...
