The Spinal Fusion Curette – Reverse Angled Up Bay 4-0 is a specialized surgical instrument designed for spinal fusion procedures, particularly when access to tight or challenging areas is needed. The "reverse angled up bay" design provides a unique angle and curvature, allowing the surgeon to efficiently scrape and remove bone and tissue in difficult-to-reach regions of the spine. The "4-0" size refers to a medium-small tip, making it suitable for precision work in areas where a delicate yet effective approach is required.
