Surgical device having trocar and associated methods

A surgical device comprising:

• a handle having a hand-gripping portion positioned adjacent a proximal end, a cannula-interface portion positioned adjacent a distal end and having a recess therein, and an instrument opening extending into and through a medial portion and also through the recess in the cannula-interface portion;
• an instrument seal having a seal opening and positioned in the medial portion of the handle adjacent the instrument opening, to seal instruments when extending through the instrument opening and seal opening;
• a tubular trocar having a proximal end portion adapted to be positioned in the medial portion of the handle adjacent the instrument opening, and having a distal end portion extending outwardly therefrom through the cannula-interface portion;
• and
• a cannula adapted to receive at least portions of the tubular trocar therethrough, having a proximal end portion adapted to be received in the recess of the cannula-interface portion of the handle, and having a distal end portion extending outwardly therefrom so that the handle supports the combination of the trocar and cannula.
