probe(spaceprobe) See planetary probe.
a medical instrument for examining hollow and tubular organs, normal and pathological canals, sinus passages, and wounds. Depending on their purpose, probes are manufactured from metal (steel, silver) or from elastic material.
By probing one may determine by touch the depth and breadth of a passage or cavity, its direction and shape, and the presence of foreign bodies. The use of hollow probes makes it possible to sample the contents of a hollow organ or to inject diagnostic and medicinal drugs (for example, a gastric probe). Certain types of probes can be attached to special instruments, making it possible to determine the pressure in the cavity of an organ, the fluctuation of electrical potentials, or the motor function of an organ (for example, probing the heart) for diagnostic purposes.

iii. An instrument boom (i.e., a boroscope). See boroscope.
