A spot-occlusion apparatus spot-coagulates or otherwise occludes an anatomical tissue structure which is disposed in a living body and has a plurality of vessels extending therefrom. The occlusion apparatus includes an elongated tubular member and an occluding mechanism. The tubular member extends along a central longitudinal axis to define a lumen and has a distal end positioned interiorly of the living body and a proximal end disposed opposite the distal end and positioned exteriorly of the living body. The occluding mechanism is operative at the distal end of the tubular member and includes a pair of articulating fingers with distal end effectors (such as occluding elements) disposed opposite one another. The pair of end effectors are moveable to and between an opened state and a closed state. In the opened state, the vessels to be occluded are received between the pair of occluding end effectors. In the closed state, the pair of occluding end effectors contact and occlude the vessels, thereby occluding the anatomical tissue structure. The articulating fingers create a working space between themselves for manipulating, coagulating and/or otherwise occluding tissue. Moreover, one or more ports is directed through the lumen into the workspace for admission of a viewing system, hydration device, cauterization device, cryo (cooling) device, suction, or any of a range of ancillary surgical implements all through a single surgical site.
