Abstract

The utility model provides a kirschner wire guider, which relates to the technical field of medical instruments and comprises a guider main body, and a guider fixing seat is arranged at one end of the guider main body. By means of the modular design, the guider body can be rapidly replaced with different diameters and length specifications, the requirements of different patients and operation scenes are met, the clamping design of the ball screws enables installation and detachment to be simple and efficient, the flexibility and convenience of operation preparation are greatly improved, and the operation efficiency is improved. The design of the inner hole of the guider body ensures that the kirschner wire is always inserted into the bone along a fixed path, and by combining the groove direction of the grooved screw and the center position alignment structure of the guider body, the accuracy of operation guiding can be remarkably improved, the risk of operation failure caused by deviation is reduced, and the operation safety is improved. The structural design of the bolt and the guide ring provides multiple supports for the guider body, it is ensured that in the using process, the guider body cannot be loosened or deviated due to the influence of external force, and the stability and reliability of the device are further improved.
