The ratchet on a hand-held instrument is specifically designed to maintain a closed position. It serves as a locking mechanism that holds the instrument's jaws or clamping surfaces securely together after being closed, which is essential during surgical procedures. This feature allows the surgeon to focus on the task at hand without worrying about the instrument inadvertently opening.

The ratchet mechanism is particularly important in instruments like clamps and forceps, where maintaining a consistent grip is crucial for effective tissue handling or securing structures. This functionality enhances precision and safety in surgical environments.

Instruments that open a body cavity, cut tissue, or retract organs usually employ different design features that do not rely on a ratchet mechanism for their intended functions. Therefore, while they are vital tools in surgery, their operational mechanisms differ significantly from that of instruments utilizing the ratchet.
