AI Technical Summary

Technical Problem

Traditional internal fixation devices typically employ a single fixation method, lacking effective resistance to forces in other directions, leading to poor fracture healing or malunion.

Method used

A controllable micro-motion elastic internal fixation device with a bidirectional locking pressure plate structure was designed. Through the combination of bridging rod, end block, fixing screw, upper and lower pressure plates, adjusting screw and friction plate, bidirectional locking and micro-motion control of the fracture site is achieved. Fine thread and biocompatible materials are used to improve fixation stability and adaptability.

Benefits of technology

It effectively resists the dynamic forces generated by muscle contraction and limb movement, prevents the fixation device from loosening or shifting, ensures the fracture healing effect, promotes fracture healing and reduces the risk of deformity.

Abstract

The utility model provides a controllable micro-motion elastic internal fixation device with a bidirectional locking pressing plate structure, and belongs to the technical field of orthopedic medical instruments. Comprising a plurality of bridging rods; and the two end blocks are arranged at the two ends of the bridging rod. A stable frame structure is constructed through the combination of the bridging rod, the end block and the fixing screw, a fracture part is effectively connected and fixed in the axial direction, then a bidirectional locking mechanism is formed through the upper pressing plate, the lower pressing plate, the adjusting lead screw and the locknut, and the fracture part is locked by screwing the locknut. The distance and pressure between the pressing plates can be accurately adjusted and locked, dynamic force generated by factors such as muscle contraction and limb movement can be effectively resisted in the long-term use process, the pressing plates are prevented from loosening or displacing, and it is ensured that the fixing device always keeps the stable fixing effect; and the problems of poor fracture healing or malformation healing and the like caused by fixation failure are avoided.
