1. A surgical instrument for irrigating a frontal sinus target site of a patient, the instrument comprising:

  • a handle;

    an elongate introducer extending from the handle and defining a proximal segment and a distal segment terminating at a distal end, the introducer rigidly forming at least a portion of the proximal segment to be relatively linear and at least a portion of the distal segment to be relatively curved as compared to the relatively linear portion in longitudinal extension of the introducer from the handle, a rigidity of the relatively linear portion and the relatively curved portion characterized by each portion not elastically deforming in response to a manually applied bending force;

    an irrigation channel comprising a tubular body extending through the introducer, the tubular body having a terminal first end, the first end disposed within the introducer adjacent to the distal end;

    a nozzle fluidly connected to the irrigation channel at the first end of the tubular body, the nozzle is maintained partially within and rotatably assembled to the distal end of the introducer such that the nozzle is rotatable relative to the introducer; and

    an actuator assembly including an actuator maintained by the handle and connected to the nozzle;

    wherein the instrument is configured such that movement of the actuator causes the nozzle to rotate relative to the introducer.
