Star Metal Cup Liner Removal Impactor

Star Metal Cup Liner Removal Impactor is a precision orthopedic instrument developed for revision total hip arthroplasty (THA) to assist in the removal of metal acetabular cup liners from compatible acetabular shell systems. It enables surgeons to apply controlled impact forces while maintaining secure engagement with the liner during extraction. The instrument features a star-shaped engaging tip engineered to fit compatible metal cup liner interfaces. This design helps maximize contact with the liner, allowing controlled transfer of impaction forces while minimizing slippage during the removal process. Its rigid shaft provides excellent force transmission and precise alignment, allowing the surgeon to direct controlled impaction to disengage well-fixed liners from the acetabular shell while preserving surrounding implant components whenever clinically appropriate. The ergonomic handle is designed to provide a comfortable and secure grip, improving stability and control during revision procedures. The balanced construction enhances handling while reducing operator fatigue during complex orthopedic surgeries. Manufactured from premium surgical-grade stainless steel , the Star Metal Cup Liner Removal Impactor offers exceptional strength, corrosion resistance, and long-term durability. Precision machining ensures accurate engagement with compatible implant systems and dependable mechanical performance. The instrument is primarily used in revision hip arthroplasty , including acetabular liner exchange and revision procedures performed by orthopedic surgeons specializing in joint reconstruction. Compatibility varies by implant manufacturer and acetabular system, and the appropriate instrument should always be selected according to the implant manufacturer’s recommendations. Fully reusable and autoclavable , the instrument is designed to withstand repeated cleaning and sterilization cycles while maintaining structural integrity, dimensional accuracy, and reliable clinical performance.
