The optical fiber cutter


Patent
Sei Optifrontier Co. and Sumitomo Electric Industries | Date: 2014-05-29

An OCT catheter and a method for manufacturing the OCT catheter, with which the operation time, manufacturing cost, and the risk of breakage of a spliced portion between a short-length fiber and an optical fiber contained in an interior member can be reduced, are provided. An OCT catheter includes an interior member that contains an optical fiber and that is to be inserted into a body, a metal tube that guides the interior member, and an optical connector. The optical connector includes a ferrule assembly including a short-length fiber and a ferrule fixed to one end of the short-length fiber, and is connectable to a rotary joint of an OCT system. The other end of the short-length fiber and one end of the optical fiber contained in the interior member are fusion-spliced together to form a spliced portion. The spliced portion is disposed in the metal tube.

An optical fiber cleaver includes a cleaver base body having a holder guide portion which positions a fiber holder holding an optical fiber, and a cleaver lid body attached to the cleaver base body to be openable and closable. A slider having a blade member piercing the optical fiber is attached to the cleaver base body to be movable in a width direction. A pawl member is arranged in one sidewall of the holder guide portion. Further, a count indication mechanism which counts and indicates the number of times the slider returns to an initial position is provided in the cleaver base body. The optical fiber cleaver is configured to enable a counting operation of the count indication mechanism only when the fiber holder is set in the holder guide portion such that the pawl member is pressed.

A method of fusion-splicing includes attaching a stab to a stub cap having a non-axisymmetric structure, positioning an embedded optical fiber to a fusion splicing working part by fixing the stub cap thereto; positioning an outside optical fiber to the fusion splicing working part; fusion-splicing the embedded optical fiber and the outside optical fiber; repositioning the embedded optical fiber to a reinforcing working part by fixing the stub cap thereto and repositioning the outside optical fiber to the reinforcing working part such that a relative positional relationship between the embedded optical fiber and the outside optical fiber becomes the same as that at the fusion splicing working part; and reinforcing a spliced portion between the embedded optical fiber and the outside optical fiber while a tension is applied to the embedded optical fiber and the outside optical fiber.

A fusion splicer includes a pair of holder installation parts for mutually butting optical fibers in a first direction, and a fusion splicing part for mutually fusing and splicing the optical fibers by a pair of electrodes opposed along a second direction, and the holder installation part includes a base fixed to a body, and a positioning member in which a base fitting part fitted into the base is formed in a lower side, and the positioning member can be attached to and detached from both of the bases after an attitude is reversed, and a center position in a width direction along the second direction in the base fitting part is arranged in a straight line of the first direction passing through a center position between the electrodes even in a state in which the positioning member is fitted into any of the bases.
