Abstract
Bone connector including a first joint and a second joint insertable and securable into respective cut bone pieces for joining the cut bone pieces. Each joint has a flat end surface flush with the cut end of the corresponding cut bone piece when secured therein. The first joint includes a stepped hole having a coaxial hole portion, a shoulder with a surface substantially perpendicular to the longitudinal direction of the joints, and an innermost engaging portion. The second joint includes a stepped shaft having a first shaft fitting the coaxial hole portion and an engaging portion for engaging the innermost engaging portion of the first joint, which hold the joints coaxially along a line, as well as a plate spring member. The joints both include cylindrical bodies of substantially equal diameter for connecting the cut bone pieces, and at least outer surface portions of the joints are made of a material having a bioactive affinity with the human body or biocompatibility with human tissue. The plate spring member is deformed as it passes the coaxial hole portion and restored to abut the surface of the shoulder perpendicular to the longitudinal direction, for locking the joints and fl…
