A surgical instrument and related method includes an instrument body, a guide shaft distally projecting from the instrument body, and a first surgical tool. The guide shaft has a guide sidewall, a guide lumen, and a clearance opening radially extending through the guide sidewall in communication with the guide lumen. The first surgical tool has an elongate body and a distal head configured to deflect relative to the elongate body from a first position to a second position. The distal head in the first position is positioned within the guide lumen along the central axis. The distal head in the second position is deflected from the central axis and extends at least partially through the clearance opening thereby vacating at least a portion of the guide lumen for introducing a second surgical tool through the guide lumen.

Instrument with integral imaging and irrigation features

A registration device, including a wand, a light guide passing through the wand, and a position sensor fixed to the wand. A light source outputs a modulated beam of light into a light guide proximal end, so that the light is emitted from a light guide distal end toward a surface in proximity to a wand distal tip. A detector receives, from the light guide proximal end, light reflected from the surface into the light guide distal end, and outputs a signal indicative of the reflected light intensity. A processor computes a distance from the distal tip of the wand to the surface by extracting a phase difference between the output beam and the reflected light from the signal, and computes a position of the surface in a sensor frame of reference responsively to the computed distance and the location of the distal tip found from the position sensor.
