Peritoneal trocar apparatus and system

A trocar apparatus comprising:

• a conduit having two parallel conduit lumens, the conduit including a first end and a second end;
• a head connected to the first end of the conduit, the head including two parallel head lumens that are aligned respectively with the two parallel conduit lumens, the head having a width that is greater than a width of the conduit to prevent the trocar apparatus from slipping into a patient at an insertion location;
• and
• a coupler connected to the head, the coupler including two parallel coupler lumens that are aligned respectively with the two parallel head lumens, the coupler including a coupling mechanism that includes a locking ratcheting mechanism having a straight rectangular bar located at a top of the coupler connected to a wall between the two parallel coupler lumens that is rotatable at a midpoint of a longer axial length of the straight rectangular bar about a center of the coupler between an unlocked position and a locked position to secure via direct contact with the straight rectangular bar, to the coupler, surgical tools located respectively within the two parallel coupler lumens.
