US12605258B2 Hip Arthroplasty Liner Removal Apparatus

The USPTO issued Patent US12605258B2 to Globus Medical, Inc. for a liner removal system used in hip arthroplasty revision surgeries. The patented method involves accessing a surgical site where an acetabular shell is already implanted, placing a rim plate with a through opening over the shell, drilling a pilot hole through the opening into the liner, removing the rim plate to expose the hole, and using a removal tool to disengage the liner from the implanted shell.

Manufacturers of hip arthroplasty components and surgical instrument suppliers should be aware of this patent's scope when developing competing liner removal solutions. Medical device companies with hip implant product lines may need to evaluate whether their liner extraction methods or instruments fall within the claims of this patent. The patent's CPC classifications indicate protection extends across multiple aspects of prosthetic hip joint construction and associated surgical instruments.
