Abstract
Abstract There is discosed a device for the resection of the front,rear and transverse portions of the head of a femur in order to apply to the knee an articulation prosthesis. This device essentially comprises a first parallelepipedal body adapted to be affixed to the distal part of the femur in order to resect the femur bone at the front and rear thereof,and a second body, cooperating with the first so as to transversely resect the distal part.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
62 words
1- A femoral resection device characterized in that said device essentially comprises a first shaped body,having a substantially parallelepipedal shape, adapted to be affixed on the distal part of a femur, for the resection of the front and rear portions thereof,and a second shaped body,cooperating with the first shaped body and coupled thereto for transversely resecting said distal part of said femur.
Claim 2
Dependent Claim
62 words
1- A femoral resection device characterized in that said device essentially comprises a first shaped body,having a substantially parallelepipedal shape, adapted to be affixed on the distal part of a femur, for the resection of the front and rear portions thereof,and a second shaped body,cooperating with the first shaped body and coupled thereto for transversely resecting said distal part of said femur.
Claim 3
Dependent Claim
63 words
2- A femoral resection device according to claim 1, characterized in that said first shaped body is provided,at its middle cross section,with a throughgoing hole,open on the two main walls of said first body and in which there is engaged a cylindrical bush restrained therein by a pair of threaded stems engaging in corresponding threaded holes longitudinally formed of said first shaped body.
Claim 4
Dependent Claim
85 words
3- A femoral resection device according to the preceding claims,characterized in that said threaded stems are provided with an end portion provided for engaging in a slot or groove formed along a perimetrical portion of said bush and extending parallel to the longitudinal axis of said bush,said bush being moreover provided with a throughgoing hole the axis of which forms a given angle with the cross axis of said bush,said angle depending on the inclination of the diaphysis-femur axis with respect to a vertical axis.
Claim 5
Dependent Claim
98 words
4- A femoral resection device,according to one or more of the preceding claims,characterized in that said first shaped body is provided with two cross throughgoing holes and,at the top face thereof,with two threaded counterbores,in said first shaped body there being moreover formed,on the sides of said central throughgoing hole,and at the top,two coplanar slots which are parallel to the top face of said first body, and,at the bottom,at least three pairs of further slots which are also coplanar but slightly downwardly slanted with respect to the rear face of said first shaped body provided for contacting said femur.
Claim 6
Dependent Claim
86 words
5- A femoral resection device according to one or more of the preceding claims,characterized in that to said top face of said first body there is coupled, through the interposition of spacer cylindrical members, a small plate having a lug the end free portion of which is right angle bent,said small plate being coupled to said first shaped body by means of two threaded holes and using,as said cylindrical spacer members, two tubular members provided with a top threaded ridge provided for engaging in said holes.
Claim 7
Dependent Claim
39 words
6- A femoral resection device,according to one or more of the preceding claims,characterized in that said device further comprises a second shaped body,of substantially parallelepipedal shape,provided with a cantilever rectangular plate including a central hole and two side holes.
Claim 8
Dependent Claim
52 words
7- A femoral resection device,according to one or more of the preceding claims,characterized in that in said second shaped body there are formed at least two cross throughgoing holes as well as a pair of slots coplanar with one another and perpendicular to said plate,and at least a pair of slanted slots.
Claim 9
Dependent Claim
22 words
8- A device according to any of the preceding claims and substantially as disclosed and illustrated for the intended task and objects.
