Abstract: Provided are an image processing device, an image processing method, and a program for recognizing an object in a three-dimensional map, which do not require collecting learning data of the three-dimensional map and can perform high-speed processing with a small load. The image processing device includes an image acquiring section that sequentially acquires a two-dimensional input image for each frame; an object type recognition executing section that attaches, to each of pixels of the input image acquired for each frame, a label indicating a type of an object represented by the pixels; and a labeling section that executes three-dimensional position recognition of a subject represented in the input image to create a three-dimensional map, based on the input image sequentially input, and attaches, to each voxel included in the three-dimensional map, the label of the pixel corresponding to the voxel.

Abstract: Provided is a surgical tool for ophthalmology that includes a nozzle portion capable of sucking a liquid, in which the nozzle portion includes an inner tube which is provided with an inner through-hole allowing the liquid to pass therethrough and an outer tube which accommodates the inner tube and is provided with an outer through-hole allowing the liquid to pass therethrough, in which the outer tube and the inner tube are disposed to be relatively movable, and in which the outer through-hole and the inner through-hole are disposed so that an overlapping region is changeable by the relative movement of the outer tube and the inner tube.
