Abstract

The invention discloses an external bone fixing device. The external bone fixing device comprises a U-shaped positioning plate, a U-shaped protection plate and bolts. U-shaped grooves are formed in two ends of the U-shaped protection plate respectively. The widths of the U-shaped grooves are slightly larger than the diameters of the bolts. The thicknesses of the U-shaped groove positions of the U-shaped protection plate are smaller than those of two lateral portions of the U-shaped protection plate. The vertical distance between two side walls of the U-shaped positioning plate is in interference fit with the widths of bases of the bolts. The thickness of the bottom surface of the U-shaped positioning plate is smaller than that of the side wall of the U-shaped positioning plate. The heightof the side wall of the U-shaped protection plate is smaller than that of the side wall of the U-shaped positioning plate. The U-shaped protection plate is arranged in an accommodating cavity of the U-shaped positioning plate. The external bone fixing device has the advantages that system accumulated tolerances can be adjusted through distance adjustment among the U-shaped positioning plate, the U-shaped protection plate and the bolts, mounting pre-stressing force can be reduced, and accordingly, implanting pain of patients can be relieved greatly.

Description

technical field [0001] The invention relates to a medical device, in particular to a bone fixation device. Background technique [0002] When the existing fixator is installed with a fixed bracket, the installation position is relatively limited, there is no suitable installation position, the fixed bracket is difficult to arrange, and the accumulated tolerance of the system cannot be adjusted, resulting in excessive installation prestress and increasing the patient's implant pressure. into pain. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide an external bone fixation device for the shortcomings of the prior art, which is convenient to use. [0004] Technical solution: An external bone fixation device of the present invention includes a U-shaped positioning plate, a U-shaped guard plate and bolts. Both ends of the U-shaped guard plate are provided with U-shaped grooves, and the width of the U-shaped groove i...
