Patent ID: 8322932

Claim:
An optical imaging device comprising: an optical probe, with an optical fiber rotatably incorporated in the optical probe; a controller which has a light source and which sends and receives a signal to and from the optical probe; and a coupling device connecting the optical probe and the controller to each other; the coupling device comprising: an adapter device comprised of a first fixing member and a first coupling terminal disposed inside the first fixing member, the first fixing member having a hollow part opened at one end; a connector device comprised of a second fixing member and a second coupling terminal disposed inside the second fixing member, the second terminal being connected to the optical fiber, the second fixing member being insertable into the first fixing member to couple together the first coupling terminal and the second coupling terminal, the second fixing member possessing an outer wall slidable along an inner wall of the first fixing member when the second fixing member is inserted into the first fixing member; the adapter device also including a housing provided with at least one curved groove; the connector device also including a housing provided with at least one projection; an elastic member in the second fixing member on a proximal end side of the second fixing member; and the groove possessing a shape which, when the second fixing member is inserted into the first fixing member in an insertion direction and the projection enters the groove, causes the projection to slide along the groove until reaching a stopped position in which movement of the projection is stopped following movement of the projection in a direction reverse to the insertion direction, with the first coupling terminal and the second coupling terminal connected to each other when the projection reaches the stopped position.
