The Cottle Periosteal Comb and Spicule Sweeper (230mm) is a surgical instrument used in ENT and maxillofacial surgeries. The periosteal comb is designed for elevating and stripping periosteum (the tissue covering bones), while the spicule sweeper helps in removing small bone fragments or spicules during nasal or sinus surgeries. The 230mm length provides a comfortable reach for the surgeon, allowing precise manipulation in rhinoplasty, septoplasty, or sinus procedures to improve access to the surgical site and ensure minimal disruption to surrounding tissues.
