Allis Forceps

What is Allis’s Forceps? This tissue holding forceps is named after Oscar Huntington Allis, an American surgeon (1836-1921) who is remembered for his contributions in orthopedic surgery. The forceps has a ratchet locking system; the terminal end of the blades bears short teeth. The teeth have grooves in between so that when the two blades meet, one tooth of the blade fits in the groove of the other blade. The blades may be curved or straight. Check the alignment of the teeth before using it for the surgery.

What is its function? It has been built to hold tough structures like aponeurosis, fascia, tendon, anterior rectus sheath and skin. As the forceps is traumatic due to its multiple teeth it can never be used on delicate structures. However it can be used to hold the delicate tissue which has to be removed during a surgical procedure.
