Many types of instruments

  • Forceps, instruments for holding tissue

When holding instruments:

  • Place only fingertips through handle loops,
    • rotation comes from wrist
    • greater control
    • quicker to pick up, put down

Most procedures are performed with a #3 handle and
  • #10 blade for large incisions
  • #11 for stab incision
  • #15 for fine precision work
