<p>The present invention relates to a sleeve for an osteosynthesis device and to an osteosynthesis device incorporating such a sleeve. The present invention allows to easily and safely remove the osteosynthesis device from a patient's body, without the risk of damages or lesions. According to the invention, thanks to the fact that the matching between the screws (30) and the sleeves (10) receiving said screws is based upon the conicity of the head of the screws (30) and of the through-hole of the sleeves (10), a little rotation of the screws (30) in the unscrewing direction immediately releases the screws from the respective sleeves; thanks to the fact that the matching between the sleeves (10) and the osteosynthesis plate (20) is based upon the conicity of the outer surface of said sleeves (10) and of the through-bores of the plate (20) receiving said sleeves, a little rotation of the sleeves (10) in the unscrewing direction immediately releases the sleeves from the plate.</p> |
