Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
144 words
A prosthetic gripping instrument for inserting or removing an orthopaedic product, the instrument comprising a first elongated arm and a second elongated arm, each arm having a proximal end and a distal end, and wherein the arms are interconnected by a connecting mechanism to allow the distal ends of each arm to be moved toward or away from each other, one of said distal ends has a first gripping jaw which is pivotally attached thereto and the other of said distal ends has a second gripping jaw which is swivelably attached thereto, wherein the first jaw is limited to pivotal movement in a single plane about an axis of a pivot pin which interconnects the first jaw to the one distal end, said axis being nonperpendicular to a first gripping surface of the first jaw, and wherein said swivelable second jaw provides multiplanar adjustability.
Claim 2
Dependent Claim
144 words
A prosthetic gripping instrument for inserting or removing an orthopaedic product, the instrument comprising a first elongated arm and a second elongated arm, each arm having a proximal end and a distal end, and wherein the arms are interconnected by a connecting mechanism to allow the distal ends of each arm to be moved toward or away from each other, one of said distal ends has a first gripping jaw which is pivotally attached thereto and the other of said distal ends has a second gripping jaw which is swivelably attached thereto, wherein the first jaw is limited to pivotal movement in a single plane about an axis of a pivot pin which interconnects the first jaw to the one distal end, said axis being nonperpendicular to a first gripping surface of the first jaw, and wherein said swivelable second jaw provides multiplanar adjustability.
Claim 3
Dependent Claim
22 words
The instrument of claim 1 wherein the second jaw swivels about a spherical member which is interconnected to the other distal end.
Claim 4
Dependent Claim
16 words
The instrument of claim 2 wherein the spherical member is positioned in a complementary spherical cavity.
Claim 5
Dependent Claim
31 words
The instrument of claim 3 wherein the other distal end includes a connecting member attached thereto wherein the connecting member includes one of the spherical member or the spherical cavity therein.
Claim 6
Dependent Claim
17 words
The instrument of claim 4 wherein the connecting member is threadably attached to the other distal end.
Claim 7
Dependent Claim
