Allis forceps are surgical instruments designed with a series of interlocking teeth at the tips, used primarily for grasping and holding tissues. These forceps are commonly employed in surgeries involving soft tissues, such as fascia or tendons, and are useful for holding or retracting tissues without causing excessive trauma. The Allis forceps provide a firm, yet gentle grip, making them ideal for procedures where tissues need to be securely held in place while being manipulated.
