|---|
| Summary: This task requires closure of a gap under tension using one interrupted suture with a slip knot technique. |
| Equipment: 2 needle drivers or 1 needle drive and 1 maryland, 1 pair of laparoscopic scissors and three 25 cm 2-0 Silk sutures on SH needle. Tension suture pad with three pairs of black dots. Rules: Use a right-handed forehand suturing technique to close the last pair of dots at the widest part of the triangular opening. The first throw must be a slip knot, followed two square knots. You will then cut both ends of your suture. Timing: The timing will start when any instrument is seen on the monitor and will stop when the tails are cut. Cutoff time: Maximum time for task completion is 5 minutes (cutoff = 300sec). If the task is not completed within the allotted time, you will be asked to stop. Errors: Accuracy = Distance in (mm) suture is outside of the target black dots Tissue Gap = Distance in (mm) between model edges between the target black dots Air Knot = any space is visible between the first knot and the model, or between subsequent knots, 10 points, each occurrence Square Knot = correct loop formation and alternating the tails 1800 during each throw, 15 points, each occurrence Breakage = 20 points if ligature is broken during any portion of exercise, each occurrence Not a full thickness bite – 10 points, each occurrence Bunny ear (tail caught in knot) – 10 points, any occurrence (all or nothing) Holding the needle while tying knots – 10pts, any occurrence (all or nothing) Tail length <5mm or > 20mm – 1pt, each individual tail Scoring Formula: Score = 300 – time – 10 (sum of errors) Proficiency Score: To be determined Expert Score: To be determined Proficiency Training Protocol: Achieve proficiency score on 2 consecutive repetitions (max 80 repetitions) Proficiency Testing (Pre- and Post-test): 1 repetition |
