The Freer tonsil knife is a surgical instrument, typically made of stainless steel, used during tonsillectomy procedures to separate the tonsils from the surrounding tissue. It is designed with a sharp blade and a handle for a surgeon’s precise control, allowing for controlled incisions and dissection of tonsillar tissue. The knife is available in various lengths and styles, including straight, curved, and angled, to accommodate different surgical approaches and patient anatomies.
