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.
Surgical Procedures: The instrument is useful in many gynecological procedures. During dilatation and curettage(D&C) Allis forceps is used to hold the anterior lip of the cervix, edges of the vagina during hysterectomy(removal of the uterus), rectus sheath during abdominal surgery, grasping of the ovary and tubo-ovarian masses in case of oopherectomy(removal of ovaries) and tuberectomy(removal of fallopian tubes).The tonsils are also held with the help of Allis during tonsillectomy(removal of tonsils) and may be used to grasp thyroid tissue and breast tissue during resection of these structures(thyroidectomy and mastoidectomy).The diseased bowels which are meant to be removed during resection anastomosis can be held with Allis as well. It may be used as towel clipper during surgeries.
