DEVICE FOR BONE FIXATION

摘要

The present invention provides a device for fixing bone comprising an expanding unit and an enclosing unit. The expanding unit provides a first end of the expanding unit and a second end of the expanding unit and comprises two or more expanding structures capable of switching between an expanded state and a contracted state. The enclosing unit encloses the expanding unit and provides that a first end of the enclosing unit is fixed at the first end of the expanding unit, and a second end of the enclosing unit is fixed at the second end of the expanding unit. When the device for fixing bone is placed inside a bone, the expanding structures of the expanding unit are switched to the expanding state and thereby unrolling the enclosing unit, and the enclosing unit is filled with a medical filler through the second end of the expanding unit.
