The invention comprises a cannula assembly kit for a trocar suitable for use in minimally invasive surgery. The cannula assembly kit comprises a cannula and a pattern generating member. The cannula has a distal end and a proximal end and comprises a flange portion at its proximal end and an elongate cannula shaft portion extending from said flange portion to its distal end and an access port through the flange portion and the elongate cannula shaft portion, such that a surgical tool of a surgical instrument can be inserted through the access port. The pattern generating member comprises a pattern light source and a projector arranged such that the pattern light source is operatively connected to the projector for projecting a light pattern. At least the projector of the pattern generating member is configured for being at least temporarily fixed to the cannula shaft portion of the cannula.
A cannula assembly kit comprising:
A trocar assembly kit comprising a cannula assembly kit and an obturator, the cannula assembly kit comprising a cannula having a distal end and a proximal end with a flange portion and an elongate cannula shaft portion extending from the proximal end to the distal end and an access port through said elongate cannula shaft portion, and a projector configured for being fixed to the cannula shaft portion of the cannula, configured to receive a light pattern, and including a computer-regulated optical element configured to project the light pattern from the distal end of the cannula, the light pattern received from a pattern light source in operable communication with the projector and configured to create the light pattern, the obturator having a distal end and a proximal end and comprising a head portion at its proximal end, a tip portion at its distal end and a rigid obturator shaft portion extending between the head portion and the tip portion, wherein the cannula and the obturator are correlated to each other to provide that the tip portion can be inserted through the access port and the head portion can be temporarily fixed to the flange portion,
