Instructions

Materials:

  • 1 banana (not overripe)
  • 1 5-0 round-bodied 13 mm monofilament non-absorbable suture

Instructions:

  1. Make a hole in the banana with a 4 mm aortic punch.
  2. Put your nondominant arm behind your back and keep it there.
  3. Start the clock.
  4. Place the first suture in the 12 o'clock position from inside the the hole to emerge approximately 4 mm from the edge.
  5. Continue around the clock placing twelve sutures radially and symmetrically.
  6. Ensure the exit hole is precise with no tearing.
  7. On completion, stop the clock.
  8. Check your results!

Insert 12 concentric sutures beginning from inside the hole to a distance 4 mm from the wound edge. The sutures should be evenly spaced from 1 to 12 o'clock.

1. Time your Suture

2. Take a Picture of your Suture

Your suture time:

Take a picture of your banana sutures. See how to line it up.

You will need to allow this site access to the camera in your browser.
