Abstract
Official abstract text for this publication.
An orthopaedic surgical instrument is disclosed. The instrument includes an impactor head and a suction cup coupled to the impactor head. The suction cup including a distal opening that is defined by an outer rim positioned proximal of the impaction surface of the impactor head. The suction cup is configured to engage the orthopaedic prosthetic component to couple the impactor head to the orthopaedic prosthetic component.
First claim
Opening claim text (preview).
The invention claimed is: 1. An orthopaedic surgical instrument, comprising: a first impactor head having a convex curved impaction surface configured to engage a concave curved surface of an acetabular cup prosthesis, a second impactor head having a concave curved impaction surface configured to engage a convex curved surface of a femoral head prosthesis, and a suction cup configured to be selectively coupled to the first impactor head and the second impactor head, the suction cup including a distal opening that is defined by an outer rim positioned proximal of the impaction surface of the first impactor head or the second impactor head when one of the impactor heads is coupled to the suction cup, wherein the suction cup is configured to engage both the concave curved surface of the acetabular cup prosthesis and the convex curved surface of the femoral head prosthesis so as to selectively couple the first impactor head to the to the acetabular cup prosthesis and the second impactor head to the femoral head prosthesis. 2. The orthopaedic surgical instrument of claim 1 , wherein: the suction cup includes an inner wall that extends distally from the proximal opening to define a cavity, and the impaction surface of the first impactor head or the second impactor head is positioned in the cavity of the suction cup when one of the impactor heads is coupled to the suction cup. 3. The orthopaedic surgical instrument of claim 2 , wherein the inner wall defines at least one corrugation. 4. The orthopaedic surgical instrument of claim 1 , wherein the suction cup includes an outer body that extends from the outer rim to a distal end, and the outer body surrounds the the first impactor head or the second impactor head when one of the impactor heads is coupled to the suction cup. 5. The orthopaedic surgical instrument of claim 1 , further comprising an elongated body that is coupled to one of the first impactor head or the second impactor head and the suction cup, the elongated body including a handle configured to be gripped by a user and an impaction plate. 6. The orthopaedic surgical instrument of claim 5 , wherein the elongated body is removably coupled to one of the first impactor head or the second impactor head and the suction cup.
