1. A guide sheath comprising:
(a) an origin port comprising a plurality of proximal channel openings;
(b) a destination port comprising a plurality of distal channel openings, the destination port being distal to the origin port;
(c) a shaft between the origin port and the destination port, the shaft comprising:
(i) a plurality of channels, each channel of the plurality of channels connecting one proximal channel opening of the plurality of proximal channel openings to one distal channel opening of the plurality of distal channel openings, the plurality of channels comprising:
(A) a tool channel, the tool channel being sized and configured to receive a tool,
(B) an endoscope channel, the endoscope channel being sized and configured to receive an endoscope,
(C) an illumination channel, the illumination channel being sized and configured to receive an illumination source, and
(D) a tool tracking sensor, the tool tracking sensor being configured to generate a signal indicating a distance to which a tool is advanced in the tool channel, and
(ii) an articulating portion at a distal end of the shaft, the articulating portion being configured to articulate, the destination port being distal to the articulating portion, and
(iii) a straight portion at a proximal end of the shaft, the straight portion being configured to remain straight during articulation of the articulating portion, the origin port being proximal to the straight portion;
(d) a first position sensor located at the destination port, the first position sensor being configured to cooperate with an image guided surgery (IGS) navigation system to determine a current position of the first position sensor;
(e) a second position sensor located proximal to the articulating portion and at the straight portion, the second position sensor being configured to operate with the IGS navigation system to determine a current position of the second position sensor;
(f) an integrated endoscope positioned within the endoscope channel, the endoscope channel being adapted to receive the integrated endoscope at the proximal channel opening of the endoscope channel and guide the integrated endoscope to the distal channel opening of the endoscope channel as the integrated endoscope is advanced into the endoscope channel;
(g) an integrated irrigation and suction tool positioned within the tool channel, the tool channel being adapted to receive the integrated irrigation and suction tool at the proximal channel opening of the tool channel and guide the integrated irrigation and suction tool to the distal channel opening of the tool channel as the integrated irrigation and suction tool is advanced into the tool channel; and
(h) an illumination source positioned within the illumination channel, the illumination channel being adapted to receive the integrated illumination source positioned at the proximal channel opening of the illumination channel and guide the integrated illumination source positioned to the distal channel opening of the illumination channel as the integrated illumination source positioned is advanced into the illumination channel;
at least one channel of the plurality of channels being configured to transfer fluid between the origin port and the destination port.
