A surgical instrument for manipulating selected tissue in a body cavity under visual inspection, comprising: (a) a probe having an upper surface, a generally closed distal end, and a lateral aperture in said upper surface and adjacent said closed distal end; wherein the upper surface adjacent to the lateral aperture is configured generally as a flat or concave surface; wherein said distal end slopes away from said upper surface in a manner such that said distal end diverts displaceable tissue it contacts away from the region of the lateral aperture and said upper surface; (b) means for accepting an optical system disposed at least partially within the probe, said system having a distal portion terminating adjacent the lateral aperture, thereby defining a viewing space between the distal portion of the optical system, and the distal end and the lateral aperture, said viewing space located within the field-of-view of the optical system; (c) a working tool mounted within the viewing space and capable of being extended from the viewing space and through the lateral aperture; and (d) means for extending the working tool outwardly from the viewing space and through the lateral aperture; (e) a grip handle rotatably connected to said probe; and (f) adjustment means for adjusting the rotational orientation between said lateral aperture of said probe and said grip handle; wherein said adjustment means is adapted to temporarily fix said rotational orientation.
