The Meltzer Adenoid Punch 8mm Basket with a 7mm Bite is a surgical instrument used for the removal of adenoid tissue, particularly during an adenoidectomy procedure. The "8mm basket" refers to the size of the cutting mechanism, which has a basket-like design that helps to securely grasp and remove adenoid tissue. The "7mm bite" indicates the size of the tissue that can be excised with each bite of the punch, allowing for precise removal.
