A 12-inch Cheatle forceps is used to transfer and handle sterilized medical instruments without causing contamination, especially when removing them from autoclaves, boilers, or formalin cabinets. They are essential for maintaining aseptic conditions during surgical procedures, and their long handle and serrated jaws allow for a secure grip on items, while also being used to hold drapes or manipulate tissues and sutures. 

Sterilized instrument transfer:

To move sterile items from a sterilizer (like an autoclave or boiler) to the sterile field without direct hand contact.

Aseptic technique:

To prevent contamination of instruments by ensuring they are handled with forceps rather than bare hands, a key part of infection control.

Surgical procedures:

To hold, manipulate, and transfer delicate materials like tissues, sutures, and dressings during an operation.

Surgical setup:

To hold surgical drapes in place during the setup of a procedure.

Veterinary use:

Similar to human medicine, veterinarians use them for manipulating tissues and removing foreign objects.
