Rongeurs must have tips inspected for knicks and misalignment and ensure what about the cups?

The return spring on handle
The proximal pivot screw
The distal cup ferrule
The jaw stop bumper
Single-action, double-action, and Kerrison rongeurs should cut through which test medium without tearing on the front third of jaw length?
Two facial tissue layers
A leather testing pad
A plastic dowel rod
An index card sheet
What outcome is expected when testing pituitary rongeurs on an index card?
They create a full punch-out
They show no visible mark
They leave a clean imprint
They score only the surface
Arthroscopy punches are commonly tested on what material, noting that IFU may vary?
Facial tissue layers
Acrylic dowel rod
Plastic index card
Leather test material
A failed arthroscopy punch test typically shows what characteristic during cutting?
Leaves only a faint impression
Tears or requires high effort
Glides without engaging tissue
Cuts cleanly with minimal force
Pin and bone cutters should cut how far into an index card during testing?
All the way through posterior jaw
Only at the tip contact point
Down to three-quarters jaw length

Which defects must pin and bone cutters be inspected for beyond cutting performance?
Loose springs comfortable grips
