Definitions
- the present invention relates to surgical instruments used in connection with a reverse hip prosthesis. More particularly, the invention has to do with a surgical tool for extracting an acetabular cup from an acetabulum.
- a reverse hip prosthesis is described in U.S. Patents Nos. 8,313,531 B2 and 8,540,779 B2.
- the prosthesis and a revision surgery method also are described in U.S. Patent No. 8,992,627 B2.
- the disclosures of these three patents are incorporated herein in their entireties by reference.
- an acetabular ball is affixed on a stem extending from the bottom of the concave surface of the acetabular cup.
- the surgical tool of the invention enables a surgeon to remove the acetabular cup by pressing the distal end of the tool against the acetabular ball while carefully rotating the tool on the ball to cause a blade to separate the cup from the acetabulum.
- acetabular cup extractor from time to time to describe the surgical tool of the invention.
- FIG. 1 is an elevation view of the surgical tool of the invention positioned on an implanted acetabular cup.
- Fig. 2 is a section view of Fig. 1.
- FIG. 3 is an elevation view of the surgical tool of the invention.
- FIG. 4 is a perspective view of the surgical tool of the invention.
- Fig. 5 is an elevation view of a driver used with the surgical tool of the invention.
- FIG. 6. Is an elevation view of a handle used with the surgical tool of the invention.
- Fig. 7 is an elevation view of a blade used with the surgical tool of the invention.
- Fig. 8 is an elevation view of an extractor cup used with the surgical tool of the invention.
- Fig. 9 is a section view of the acetabular cup extractor of Fig. 3 and the driver of Fig. 5.
- the acetabular cup extractor 1 is illustrated in elevation in Fig. 3 and in perspective in Fig. 4. In Figs. 1 and 2, elevation and section views, respectively, the extractor 1 is positioned on an acetabular ball 5 which is affixed to the stem 11 of acetabular cup 3. The acetabular cup 3 is implanted in acetabular bone 4. The extractor cup 2 is in articulating contact with acetabular ball 5 and the distal end of blade 6 is positioned between the convex outer surface of cup 3 and bone 4.
- the extractor cup 2 is carefully rotated on acetabular ball 5 to cause blade 6 to move along or in close proximity to the convex surface of acetabular cup 3, thereby rotating the blade 6 around the convex surface and adjacent or in close proximately to said surface so that the blade is between the acetabular cup 3 and the acetabulum.
- This movement causes the bone 4 of the acetabulum to be separated from the cup 3.
- the surgeon pushes the acetabular cup extractor 1 downwardly so that the extractor cup 2 contacts the acetabular ball 5 and a distal portion of blade 6 is caused to move into acetabular bone 4 in a position adjacent or in close proximity to the convex surface of acetabular cup 3.
- Blade 6 comes in various sizes such that the portion of the blade designated as "L" in Fig. 7 varies in length. Multiple blades of different lengths can be used, always starting with the shortest blade length, then using the next longest length, etc. For example, if three blades are used, the shortest length blade is used first and at least one complete rotation of the blade between the acetabular cup 3 and the bone 4 is completed. In other words, the blade 6 is rotated at least 360 degrees around the cup. Then the next longest blade length is used and at least one complete rotation of the blade between the acetabular cup 3 and bone 4 is completed.
- the acetabular cup extractor 1 is comprised of a handle 7 made of a shaft 8 and a movable lever arm 9 as shown in Fig. 6.
- the lever arm facilitates rotation of extractor 1 while maintaining downward pressure on extractor 1.
- Driver wrench 10 illustrated in elevation in Fig. 5, is used to fasten and unfasten the extractor cup 2a to and from shaft 8 of handle 7.
- Extractor cup 2a is an optional embodiment which is threaded into shaft 8a as illustrated in section in Fig. 9 (The extractor cup 2 of Fig. 8 is snap fit into shaft 8.) A section view illustrating the position of these elements in the fastening and unfastening operations is provided in Fig. 9.
- any screws or other connectors extending from acetabular cup 3 into bone 4 are removed. If necessary, acetabular ball 5 is removed in order to gain access to the screws. Then acetabular ball 5 is placed back on the stem of the acetabular cup and the cup removal process is continued. Blade 6 is then pushed into the bone adjacent the convex surface of the acetabular cup until the extractor cup 2 is in contact with acetabular ball 5. While pressing the extractor cup 2 against the acetabular ball 5, the acetabular cup extractor 1 is rotated on acetabular ball 5, thereby causing blade 6 to loosen the connection between acetabular cup 3 and the bone 4. When the acetabular cup 3 is sufficiently loosened from bone 4 after using blades 6 of increasing length as explained above, the acetabular cup is lifted of the bone.
- the acetabular cup removal tool of the invention may be included in a kit comprising other surgical tools and/or implants.
