What are box locks used for?

• A. To connect and pivot the jaws or blades of an instrument
• B. To secure the instrument during use
• C. To store the instrument when not in use
• D. To measure the tension in surgical sutures

Answer: (A)

Box locks are integral components of surgical instruments, particularly those that involve moving parts, such as scissors or forceps. Their primary function is to connect and pivot the jaws or blades of an instrument, allowing for smooth and controlled operation during surgical procedures. This connection ensures that the jaws move in coordination, enabling precise movements necessary for effective tissue handling or dissection.

By providing a stable pivot point, box locks contribute to the overall functionality and reliability of surgical instruments, allowing for better control by the surgeon. This mechanism is vital for maintaining performance standards in surgery, as it directly affects how easily and accurately the instrument can be manipulated.

Other choices present different functions which are not accurate for box locks. While securing instruments during use or measuring tension in surgical sutures may pertain to other mechanisms or tool features, it is the box lock's unique design that specifically allows for the pivotal action of instrument jaws that makes it essential in surgical practice.
