Forceps

Forceps or forcipes are a handheld, hinged instrument used for grasping and holding objects. Forceps are used when fingers are too large to grasp small objects or when many objects need to be held at one time while the hands are used to perform a task. The term 'forceps' is used almost exclusively within the medical field. Outside medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps.

'Forceps' can be used as both the singular and plural form of the word. (Example: "I need a forceps.") Also, it is not referred to as a "pair" as one refers to a "pair of scissors". Etymologically, the word derives from the Latin forca, meaning a snare or trap.

Mechanically, forceps employ the principle of the lever to grasp and apply pressure.

Surgical forceps are commonly made of high-grade carbon steel, which ensures they can withstand repeated sterilization in high-temperature autoclaves. Lower quality steel is used in forceps made for other uses. Some forceps, intended to be used once and then discarded, are made of plastic. The invention of surgical forceps is attributed to Stephen Hales

There are two basic types of forceps: non-locking (often called 'thumb forceps' or 'pick-ups') and locking, though these two types come in dozens of specialized forms for various uses. Non-locking forceps also come in two basic forms, hinged at one end, away from the grasping end (colloquially such forceps are called tweezers, though a medical professional would not likely refer to them as such) and hinged in the middle, rather like scissors (though, unlike scissors, forceps are tipped with flat, grasping surfaces rather than interposing blades). Locking forceps are almost always hinged in the middle, though some forms place the hinge very close to the grasping end. Locking forceps use various means to lock the grasping surfaces in a closed position to facilitate manipulation or to independently clamp, grasp or hold an object.
