Deep Tie Knot :
Sometimes, the tissues to be sutured are not on the surface and therefore, they are quite difficult to access and to perform a knot with comfortability using the previously described techniques.
In these cases, the knot will have to be done on the surface and then slipped down to the desired position.
1. Tissue to be sutures lies at deep. Strands to be knotted come to the surface.
2. Make a simple knot on the surface (left over right strand).
3. Use your index finger to push the knot to its final position.
4. Make sure that the knot is tight by further pushing down your index finger.
5. Make a second simple knot on the surface (right over left strand).
6. Push this second knot down in the same manner as before.
7. Further push down with your index finger to complete a deep square knot.
