Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
186 words
A set of parts for forming a femoral prosthesis, this set comprising at least: a) a part forming a shaft (1) defining a femoral shaft having an axis (12) and intended to be implanted in the femur along the general direction of the medullary canal, b) a part forming a head (3, 3a) defining a femoral head intended to be accommodated in the pelvis, with the possible interposition of a prosthetic cotyle, and c) a first connecting part (2b) defining a femoral neck intended to join the femoral shaft and the femoral head, the part forming the shaft and the first connecting part comprising means (5, 7, 4, 6) for the assembly of the latter with the part forming the shaft in different positions round an assembly axis (8) and the connecting part (2b) being shaped so that to its different assembly positions on the part forming the shaft, there correspond different fitted positions of the femoral head round the assembly axis, characterized in that the assembly axis (8) is inclined relative to the axis (12) of the shaft and is orientated towards the femoral head.
Claim 2
Dependent Claim
186 words
A set of parts for forming a femoral prosthesis, this set comprising at least: a) a part forming a shaft (1) defining a femoral shaft having an axis (12) and intended to be implanted in the femur along the general direction of the medullary canal, b) a part forming a head (3, 3a) defining a femoral head intended to be accommodated in the pelvis, with the possible interposition of a prosthetic cotyle, and c) a first connecting part (2b) defining a femoral neck intended to join the femoral shaft and the femoral head, the part forming the shaft and the first connecting part comprising means (5, 7, 4, 6) for the assembly of the latter with the part forming the shaft in different positions round an assembly axis (8) and the connecting part (2b) being shaped so that to its different assembly positions on the part forming the shaft, there correspond different fitted positions of the femoral head round the assembly axis, characterized in that the assembly axis (8) is inclined relative to the axis (12) of the shaft and is orientated towards the femoral head.
Claim 3
Dependent Claim
24 words
A set according to claim 1, characterized in that it comprises at least two parts forming heads (3, 3a) defining heads of different diameters.
Claim 4
Dependent Claim
33 words
A set according to one of claims 1 and 2, characterized in that the connecting part and the part forming the head can be fitted together by small-angled conical bearing surfaces (9, 10).
Claim 5
Dependent Claim
66 words
A set according to one of the preceding claims, characterized in that it comprises, moreover, a second connecting part (2) defining a femoral neck intended to join the femoral shaft and the femoral head and comprising means (4, 6) for its assembly with the part forming the shaft, replacing the first connecting part (2b), so that the femoral head is centred on the assembly axis (8).
Claim 6
Dependent Claim
170 words
A set of parts for forming a femoral prosthesis, this set comprising: a) a part forming a shaft (1) defining a femoral shaft having an axis (12) and intended to be implanted in the femur along the general direction of the medullary canal, characterized in that it comprises at least b) a first connecting part defining a femoral head intended to be accommodated in the pelvis, with the possible interposition of a prosthetic cotyle, and a femoral neck intended to join the femoral shaft and the femoral head, the part forming the shaft and the first connecting part comprising means for the assembly of the latter with the part forming the shaft in different positions round an assembly axis (8) and the connecting part being shaped so that to its different assembly positions on the part forming the shaft, there correspond different fitted positions of the femoral head round the assembly axis, which is inclined relative to the axis (12) of the shaft and is orientated towards the femoral head.
Claim 7
Dependent Claim
170 words
A set of parts for forming a femoral prosthesis, this set comprising: a) a part forming a shaft (1) defining a femoral shaft having an axis (12) and intended to be implanted in the femur along the general direction of the medullary canal, characterized in that it comprises at least b) a first connecting part defining a femoral head intended to be accommodated in the pelvis, with the possible interposition of a prosthetic cotyle, and a femoral neck intended to join the femoral shaft and the femoral head, the part forming the shaft and the first connecting part comprising means for the assembly of the latter with the part forming the shaft in different positions round an assembly axis (8) and the connecting part being shaped so that to its different assembly positions on the part forming the shaft, there correspond different fitted positions of the femoral head round the assembly axis, which is inclined relative to the axis (12) of the shaft and is orientated towards the femoral head.
Claim 8
Dependent Claim
63 words
A set according to claim 5, characterized in that it comprises, moreover, a second connecting part defining a femoral head and a femoral neck intended to join the femoral shaft and the femoral head, and comprising means for its assembly with the part forming the shaft, replacing the first connecting part, so that the femoral head is centred on the assembly axis (8).
Claim 9
Dependent Claim
30 words
A set according to one of the preceding claims, characterized in that the assembly axis (8) forms an angle of at least 110' with the axis (12) of the shaft.
Claim 10
Dependent Claim
39 words
A set according to one of the preceding claims, characterized in that the femoral head has a spherical surface whose centre is situated near the assembly axis when the prosthesis is fitted together by using the first connecting part.
Claim 11
Dependent Claim
31 words
A set according to one of the preceding claims, characterized in that the part forming the head and the connecting part can be fitted together by small-angled conical parts (4, 5).
Claim 12
Dependent Claim
41 words
A set according to claim 3 and claim 9, characterized in that at least one connecting part ends in two male cones (4, 9) for the assembly with the part forming the shaft and with the part forming the head respectively.
Claim 13
Dependent Claim
27 words
A set according to claim 10, characterized in that the male cones of the first connecting part have separate axes forming a small angle (n) between them.
Claim 14
Dependent Claim
35 words
A set according to one of the preceding claims, characterized in that it comprises at least two first connecting parts (2a, 2b) and at least two second connecting parts defining femoral necks of different lengths.
