How it works
Step 01
Trocar inserted into port site opening to depth of markings (observed from telescope in another port).
Step 02
Needle carrying the suture pushed through trocar conduit, muscle tissue and into the abdominal cavity.
Step 03
Needle withdrawn to create loop to be grabbed by forceps from a different port.
Step 04
One end of suture pulled through into abdominal cavity with forceps.
Step 05
Needle withdrawn from trocar.
Step 06
Trocar pulled outwards to reveal lower opening of conduit so that suture can be removed from conduit.
Step 07
Trocar rotated about 180° (or smaller angles as appropriate for location of suture around port opening) and pushed back inwards to level of markings.
Step 08
Needle reinserted into trocar conduit, through muscle tissue and into abdominal cavity on other side of opening.
Suture grasped by suture carrying needle.
Step 08a
Needle withdrawn so that point is just within the trocar (mark on supplied needle at point of asterisk assists this manoeuvre).
Step 08b
Trocar rotated to site of next suture while thread still grasped by the needle.
Step 08c
Needle reinserted into abdominal cavity, suture released from needle and end pulled through with forceps into abdominal cavity.
Step 08d
Trocar rotated to final exit point of suture, needle reinserted and suture re-engaged, withdrawn and tied as for single suture.
