The Allis clamp is a surgical instrument with sharp teeth, used to hold or grasp heavy tissue. It is also used to grasp
fascia and soft tissues such as
breast or
bowel tissue.[1] Allis clamps can cause damage, so they are often used in tissue about to be removed.
When used to grasp the
cervix to stabilize the
uterus, such as when an
intrauterine device is being inserted, an Allis clamp has the advantage of causing less bleeding than the more commonly used
tenaculum.[2]
