Patent ID: 7828823

Claim:
An invertebral connection device, comprising: a female member comprising a cavity and intended to be connected to a first vertebra, said cavity having an opening and a bottom surface opposite said opening; a male member articulated in the cavity and intended to be connected to a second vertebra, the male member extending both inside and outside said cavity through said opening, the male member comprising a lateral articulation surface coacting with a lateral surface of the cavity to guide inclination movements of the male member relative to the female member, the male member being movable to the female member also in axial translation; and first and second resilient means for damping said relative inclination and axial movements of the male and female members, wherein the first resilient means is disposed in a recess of the male member, said recess being delimited at a recess's lateral outer portion by an inner surface of a wall of the male member, said articulation surface forming an outer surface of said wall opposite said inner surface, wherein the first resilient means is located axially between a bottom surface of said recess and a bearing member that extends transversely through the male member leaving play between the bearing member and the male member and that is fixed at the bearing member's two ends to the female member, wherein the second resilient means is disposed in the cavity and is located axially between said bottom surface of the cavity and the male member, wherein the bearing member is located axially between said opening and the bottom surface of the recess and wherein the bottom surface of the recess is axially between the bottom surface of the cavity and the bearing member.
