Osteosynthesis clip and insertion tool for use with bone tissue fragments
An osteosynthesis clip for the cicatrization of bone tissue fragments and an insertion tool for inserting the clip are provided. The clip includes at least two engagement legs extending approximately parallel to one another and including respective distal bridging tips and respective proximal insertion tips to be inserted into the bone tissue fragments; and a connecting bridge coupled to the distal bridging tips of the two engagement legs, 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.
1. A method for inserting an osteosynthesis clip into bone tissue fragments, the clip including at least two engagement straight legs extending approximately parallel to one another in a first direction and including respective distal bridging tips and respective proximal insertion tips; and a connecting bridge coupled to the distal bridging tips of the two engagement straight legs, the connecting bridge extending in a second direction perpendicular to the first direction and including at least two elongated sections extending along side one another, the elongated sections extending along a non-linear curved trajectory to form a non-linear curved deformable region, the method comprising:
pre-drilling the bone tissue fragments with respective clip reception holes to respectively receive the engagement straight legs of the osteosynthesis clip;
inserting the straight legs of the clip into the pre-drilled reception holes in the bone tissue fragments;
applying a first force to separate the elongated sections of the clip from one another in a third direction perpendicular to the first and second directions to cause the engagement straight legs of the clip to approach one another and to cause the bone tissue fragments to come in contact with one another under pressure; and
applying a second force to the elongated sections of the clip in an area of the non-linear curved deformable region in the first direction to cause at least a partial linearization of the non-linear deformable region while applying a third force opposed to the second force in the first direction to the distal bridging tips to cause the proximal insertion tips to pivot toward one another about the distal bridging tips of the clip while preventing the straight legs of the clip from being withdrawn from the bone tissue fragments.
2. The method of claim 1 , wherein the clip is inserted into the bone tissue fragments by a percussion force applied to an instrument coupled to the clip.
3. The method of claim 1 , further comprising:
bringing the elongated sections closer together if the bone tissue fragments come in contact with one another under too high a pressure.
4. The method of claim 1 , wherein the second force applied to the elongated sections is an upward force, and wherein the applied third force is a downward force on the distal bridging tips of the clip while the upward force is applied to the elongated sections of the clip.
5. The method of claim 1 , wherein the non-linear curved deformable region includes one of a depression and a dome.
