An instrument with two blades and a handle used for handling, grasping, or compressing. Many types of forceps are employed in medicine, including the alligator forceps (an angled instrument with jaws at the end), tissue forceps (a form of tweezer), hemostatic forceps (also simply called a hemostat, to clamp a bleeding vessel), mosquito forceps (a small hemostat) and obstetrical forceps (to aid in delivering a baby). The word "forceps" comes directly from the Latin for an instrument designed to grasp, pluck, or lift. The term was derived from "formus" =(hot) + "capere" (to grasp) and designated an instrument used to grasp something too hot to handle with ones hands.

a pincer-like instrument designed to grasp an object so that it can be held firm or pulled. Specially designed forceps - of which there are many varieties - are used by surgeons and dentists in operations. The forceps used in childbirth are so designed as to fit firmly round the baby's head without damaging it. Dental extraction forceps are specially designed to fit the various shapes of teeth. By having long handles and short beaks they provide considerable leverage.
