We often use tweezers in our daily life. Doctors also use medical forceps when they operate on patients. But what is the difference between forceps and tweezers?




The crocodile forceps are a hand-held, hinged tool for grasping objects. When the fingers are too large to grasp small objects, or when many objects need to be held at one time, alligator forceps are used. The term "forceps" is used almost exclusively in the medical field. Outside of medicine, hartmann ear forceps are commonly referred to as tweezers, clips, tongs, pliers or clamps.


Mechanically, medical clamps forceps use the principle of leverage to grasp and apply pressure. 


According to its function, the basic surgical crocodile ear forceps can be divided into the following groups: 


Non-disposable sutter bipolar forceps. They should be able to withstand the physical and chemical effects of body fluids, secretions, detergents and sterilization methods.


EN-3006L Stainless Steel Crurotomy Scissors

Disposable kocher forceps. They are usually made of low-quality materials or plastics that are easy to handle after use. Surgical adsons forceps are usually made of advanced carbon steel to ensure that they can withstand repeated sterilization in high temperature and high pressure sterilizers. Some are made of other high quality stainless steel, chromium and vanadium alloys to ensure durability and rust-free edges. Forceps of low quality steel for other purposes. Some disposable sponge holder forceps are made of plastic.


The forceps can be divided into two main types, one is the non-locking forceps, also known as thumb forceps, and the other is the locking forceps. These two types have dozens of special forms for different purposes. Non-locking forceps also come in two basic forms: hinged at one end, away from the grasping end and hinged in the middle, rather like scissors. Locking forceps are almost always hinged in the middle, although some forms place the hinges very close to the griping end. The locking forceps use various means to lock the grip surface in a closed position for ease of operation or independently clamping, grasping or holding objects.




Tweezers are small tools for picking up objects too small to be handled easily by human fingers. The term most likely derives from tongs, pincers, or scissors-like pliers used to grab or hold hot objects since the dawn of recorded history. In scientific or medical contexts, they are often referred to as forceps.


Tweezers are commonly used for tasks such as pulling out hair from the face or eyebrows, often using the term eyebrow tweezers. Other common uses of tweezers are as tools for manipulating small objects,  for example, surface mountings, electronic components, and small mechanical components for models and precision mechanisms. Stamp collectors use stamp tweezers to process stamps, which, although large enough to be picked up directly by hand, can be destroyed by fingers. The jaws of the stamp tweezers are smooth and do not scratch the stamp. In addition to these uses, tweezers will also be used in the kitchen. For example, you can use tweezers to remove bones from fish fillets, or you can use tweezers to remove hair from pig skin.
