Study on Unilateral Composite Type External Fixation Device in Field Battle

Objective To introduce a new field battle unilateral external fixation. Methods According to the mechanical principles design, in the summary of unilateral external fixation to improve it. The round nail holes and nail-round slot in threaded rod have been instead by nail-round slot at both ends of threaded rod. There are several tapping holes between the numbers of nail-round slot. The bone screws have been instead by small self-tapping screw. Results The structures of external fixation devoice are simple and novelty and the manipulation of it is convenience. Meantime it has the privileges of light weight, little volume and secure stabilization. Conclusion The design of the new external fixator can be applied in extremity fractures without power tool and crank drill, so it can be elevated battle force in the field battle.
