Patent ID: 8764843

Claim:
Ex-vivo cotyle assembly comprising: a metal insertion shell ( 1 ), having a substantially hemispherical convex exterior anchor face ( 2 ) conformed to be anchored in a cotyle cavity in the pelvis of a patient, and having a concave receiving face ( 3 ) with an annular edge ( 9 ), a ceramic fixed final joint insert ( 4 ), distinct from, and being manufactured separately from, the insertion shell ( 1 ), having an exterior face ( 5 ) ex-vivo engaged in the concave receiving face ( 3 ) of the insertion shell ( 1 ), and having an interior receiving face ( 6 ) including a substantially hemispherical concave joint surface ( 7 ) to enable the engagement and the pivoting of a femoral prosthesis head or of a mobile joint insert, the ceramic fixed final joint insert ( 4 ) having a thickness (E′) less than or equal to approximately 4 mm, wherein: the insertion shell ( 1 ) has, in a vicinity of its annular edge ( 9 ), a thickness (E) less than or equal to approximately 4 mm and greater than 2 mm, the insertion shell ( 1 ) comprises a peripheral receiving structure ( 8 ) projecting beyond the receiving face ( 6 ) of the fixed final joint insert ( 4 ) inserted in the insertion shell ( 1 ) and including an annular receiving face ( 10 ), wherein the insertion shell ( 1 ) and the ceramic fixed final joint insert ( 4 ) each have conical surfaces, wherein said conical surfaces bear upon each other when the insert ( 4 ) is impacted against the insertion shell ( 1 ), and wherein a placement and orientation insert ( 11 ), including an assembly structure ( 12 ) to which the impacter ( 15 ) can be removably fixed, is removably fixed to the annular receiving face ( 10 ) of the insertion shell ( 1 ) in the presence of the ceramic fixed final joint insert ( 4 ), in order to enable an impaction of the ex-vivo assembly into the pelvis of a patient, providing a simultaneous impaction of the metal insertion shell ( 1 ) and of the ceramic fixed final joint insert ( 4 ) into the pelvis of the patient, and wherein the insertion shell ( 1 ), the ceramic fixed final joint insert ( 4 ) and the placement and orientation insert ( 11 ) are assembled and packaged in a microbial protection envelope in a sterile state, with the ceramic fixed final joint insert ( 4 ) engaged in the insertion shell ( 1 ), and with the placement and orientation insert ( 11 ) fixed to the insertion shell ( 1 ).
