MATERIAL REMOVAL FROM SURGICAL SITE
A fluid source on a carrier is configured to rotate relative to a probe to direct a fluid stream from the source toward an opening of an evacuation lumen. This may help to remove material that may collect near the opening, such as blood clots and tissue. Also, directing the fluid stream toward the evacuation lumen can draw flowable material from the surgical site toward the evacuation lumen to improve removal of material from the surgical site.
1 .- 48 . (canceled)
49 . A tissue treatment apparatus comprising:
a carrier comprising an aperture configured to deliver energy for treating tissue at a surgical site of a patient, the carrier comprising a longitudinal axis;
a probe configured to be inserted into the patient, the probe comprising an evacuation lumen configured to remove material from the surgical site; and

wherein the opening comprises a cross-sectional area sized larger than a cross-sectional area of the aperture,
wherein the carrier is configured to rotate the aperture around the longitudinal axis to a first position toward the opening to direct the energy toward the opening, and
wherein the carrier is configured to rotate the aperture around the longitudinal axis to a second position away from the opening to direct the energy towards the tissue.
50 . The apparatus of claim 49 , wherein the distal end of the probe comprises a recess sized and shaped to receive a distal end of an energy delivery probe extending from the carrier, the recess configured to stabilize the energy delivery probe.
51 . The apparatus of claim 49 , wherein the carrier comprises an energy delivery probe that includes the aperture.
52 . The apparatus of claim 51 , wherein the carrier supports an endoscopic camera comprising a sensor array.

55 . The apparatus of claim 51 , wherein the energy delivery probe is configured to rotate in relation to the carrier to direct the aperture to deliver the energy at an angle toward the tissue.
56 . The apparatus of claim 51 , wherein a distal end of the energy delivery probe protrudes beyond a distal end of the carrier by a distance that remains substantially fixed when the carrier translates and the energy delivery probe rotates.
57 . The apparatus of claim 49 , wherein the carrier comprises one or more irrigation channels extending to one or more irrigation channel openings.
58 . A tissue treatment apparatus comprising:
an energy delivery probe comprising an energy source configured to emit an energy toward a tissue at a surgical site of a patient, the energy delivery probe comprising a longitudinal axis;
a carrier configured to support the energy delivery probe, the carrier configured to rotate the energy delivery probe to direct the energy to treat the tissue;
a probe configured to be inserted into the patient, the probe comprising an evacuation lumen configured to remove material from the surgical site; and
an opening defined by a distal end of the evacuation lumen and a portion of the probe extending beyond the carrier,
wherein the energy delivery probe is configured to rotate the energy source around the longitudinal axis to a first position toward the opening to direct the energy toward the opening, and
wherein the energy delivery probe is configured to rotate the energy source around the longitudinal axis to a second position away from the opening to direct the energy towards the tissue.
