Most programs require students master the two-handed, one-handed square knots, and instrument-tie square knots, how to load the needle driver, and how to suture tissue without tearing it or applying undue stress to the needle. Although your suture practice kit will provide the tools, these cannot replace hours of repetition needed for successful suture practice. Of course, some of the things to be aware of and avoid while practicing suturing techniques are:
Skin inversion is caused by failing to enter skin at a perpendicular angle
Half-hitches rather than square knot occur when the knot is not carefully inspected prior to tightening.
Air-knots occur when insufficient tension is applied to the knots and between the surface and the knot.
That said, your surgery practice kit will contain everything needed for hours of repetition needed to master the art of sutures.
