Allis forceps are surgical instruments used to grasp, hold, and retract dense or slippery tissues, such as fascia, ligaments, breast, or intestinal tissue, during various surgical procedures including general, orthopedic, gynecological, and thoracic surgeries. Their distinctive design features interlocking teeth for a secure grip, allowing surgeons to achieve a firm hold for manipulation, dissection, suturing, or to create a clear surgical field.
