摘要：
The present invention provides a device for bone fixation that includes: an expanding unit and an enclosing unit. The expanding unit includes two or more expanding structures capable of switching between an expanded state and a contracted state. The expanding unit includes a first expanding structure located near a first end thereof and a second expanding structure located near a second end thereof. The enclosing unit encloses the expanding unit and has a first end and a second end. The first end of the enclosing unit is secured at the first end of the expanding unit, and the second end of the enclosing unit is secured at the second end of the expanding unit. When the device for bone fixation is placed inside a bone, the expanding structures of the expanding unit are switched to the expanding state and thereby propping up the enclosing unit.
