Abstract
The utility model relates to an orthopedic external fixator bone nail locking device, which is provided with a clamping block which is arranged on a main axis of a fixator and a fastening bolt which penetrates the clamping block is provided with a nut at on one end, as well as a steel nail fixing rod which is used for installing a steel nail, the structure is characterized in that the clamping block is an integral open-type structure which is provided with a hole consistent with the cross-sectional shape of a main axis of the fixator at one end and is provided with an opening at the other end, and the steel nail fixing rod is arranged at the other end of the fastening bolt. The utility model increases the clamping force on the main axis and the steel nail fixing rod, and improves the clamping effect, furthermore, the steel nail fixing rod can rotate one circle around the fastening bolt and increase the degree of flexibility of the use.
Description
Technical field
This utility model relates to the utensil technical field that is used for synthetism.
Background technology
By the patent No. of the applicant invention be ZL96204637 universal adjustable fracture external fixator since the position and the direction of its bone screw holes can adjust arbitrarily, make the distance and the direction of boring limited by the strictness of holder, thereby be used widely clinically.But the nail fixture of in use finding this holder still has following deficiency: the one, and volume is bigger, and range of activity is subjected to certain limitation; The 2nd, because of fastening bolt can not be too big, cause the clamping force relative deficiency, be easy to generate looseningly, influence fixed effect.
Summary of the invention
Task of the present utility model provides a kind of clamping better effects if, uses orthopaedics external fixer nail locking device more flexibly.
This nail locking device has the fixture block that is contained on the fixed mount main shaft and passes the fastening bolt that fixture block one end is equipped with nut, and the steel nail fixed bar that is used to install steel nail, its construction features is that fixture block is that an end has the integral finish formula structure that has opening with the corresponding to hole of fixed mount main shaft cross sectional shape, the other end, and the steel nail fixed bar is contained in the other end of fastening bolt.
This utility model is under the big or small constant prerequisite of fastening bolt, increased clamping force, improved the clamping effect, avoided in use occurring loosening phenomenon main shaft and steel nail fixed bar, and the steel nail fixed bar can take up fixing bolt does week rotation, has increased the flexibility ratio of using.
