An improved osteosynthesis clip for the cicatrization of bone fragments, an improved insertion tool and method for inserting the improved clip and a surgical system implementing the improved clip and insertion tool are provided. The clip includes at least two engagement legs extending approximately parallel to one another and including insertion tips to be inserted into the bone tissue fragments; and a connecting bridge coupled to the at least two engagement legs at portions opposite the insertion portions, the connecting bridge including at least two elongated sections extending along side one another, the elongated sections extending along a non-linear trajectory to form a non-linear deformable region, such as a depression or a dome, wherein the engagement legs having respective helical screw surfaces extending substantially an entire distance between respective insertion and opposite portions to facilitate removal of the clip after the bone tissue fragments have fused. The improved clip may be made of any biocompatible material, including shape memory alloys, such as Nitinol. The insertion tool is improved to apply force at the bridging tips of either a stepped on a non stepped clip.
