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.
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.
