How should you interpret the lock setting on a hemostat during use?

• A. Confirm that the instrument is securely locked at the desired force; avoid over-tightening which can damage tissue.
• B. Lock as hard as possible every time.
• C. Locking is optional.
• D. Locking should be avoided to prevent tissue damage.

Answer: (A)

Using the lock on a hemostat is about applying a controlled, steady clamping force and keeping it in place without continuous hand pressure. Lock at the level of force needed to secure the vessel or tissue, then leave the jaws in that position while you complete the task. This provides consistent compression, prevents slippage, and frees your other hand for suturing or manipulating tissue. Avoid over-tightening because excessive pressure can crush tissue and vessels, risking damage, ischemia, or unnecessary trauma to surrounding structures. Verify the lock by checking that the ratchet engages and the handles stay closed; release and adjust if the tissue status changes or you need to reposition. Use locking judiciously—employed when stable compression is beneficial, not as a default for every step.
