A rugged dual-view arthroscope (10) construction is provided by encasing the optical train (48) in an elongated channel or shoe (50) which is pivotable within the barrel (16) about the barrel axis (36). The axis (46) of the optical train is offset from the barrel axis (36). A lens (26)-and-prism (20) assembly projects the image of a first field of view along the optical train axis (46) in one pivotal position of the shoe, and the image of a second field (28, 24) of view along the optical train axis in another pivotal position of the shoe. |
