Final answer:
Potts-Smith scissors are used to precisely extend an arteriotomy due to their specialized design with long, slender, and angled blades.
Step-by-step explanation:
The scissors commonly used to extend an arteriotomy are Potts-Smith scissors. Potts-Smith scissors have a special design that includes a long, slender, and angled blade which allows surgeons to make precise cuts and extend arterial incisions with care. This particular design facilitates a clean and controlled approach to extend the arteriotomy without causing unnecessary damage to the surrounding vascular tissue. Other scissors such as Knight, Mayo-Stille, or Jorgenson have different specialized uses in surgical procedures and are not typically used for arteriotomy extensions.
