The Daubenspeck Bone Curette 2.8mm 4-0 is a fine, precision surgical instrument used in orthopedic and neurosurgical procedures for scraping, debriding, or removing small amounts of bone or soft tissue. The 2.8mm tip offers excellent control in confined or delicate areas, while the 4-0 size designation typically refers to its slender profile, making it ideal for microsurgical work or procedures involving fine anatomical structures.
