How it works
Trocar inserted into port site opening to depth of markings (observed from telescope in another port).
Needle carrying the suture pushed through trocar conduit, muscle tissue and into the abdominal cavity.
Trocar pulled outwards to reveal lower opening of conduit so that suture can be removed from conduit.
Trocar rotated about 180° (or smaller angles as appropriate for location of suture around port opening) and pushed back inwards to level of markings.
Needle reinserted into trocar conduit, through muscle tissue and into abdominal cavity on other side of opening.
Suture grasped by suture carrying needle.
Needle withdrawn so that point is just within the trocar (mark on supplied needle at point of asterisk assists this manoeuvre).
Needle reinserted into abdominal cavity, suture released from needle and end pulled through with forceps into abdominal cavity.
