Long-Shaft Bone Curette (specifically a Brun type or long femoral/acetabular canal curette variant).

It is engineered to scrape, clean, and scoop out fibrous tissue, cartilage, pathological bone lesions, or debris from deep, confined skeletal cavities. It is widely used during hip and knee arthroplasty revisions to clear out hard-to-reach areas like the femoral canal or the acetabular cup margin.
