    摘要： Provided is an endoscope (10) including: a hand operation section (12); an insertion section (14) including a leading end part (42), a curving part (40), and a flexible part (38) that are placed in the stated order from a leading end side to a base end side on which the hand operation section (12) is placed, the leading end part (42) having a leading end surface (44) on which an observation window for observing an inside of a subject's body is provided, the curving part (40) being remotely operated for curving by operating the hand operation section (12) so as to cause the leading end part (42) to face a desired direction, the flexible part (38) connecting the curving part (40) with the hand operation section (12) and being able to curve in a desired direction along an insertion into the subject's body; a gas supply channel formed inside of the insertion section (14); and a gas jetting port (54, 64, 68) that is communicated with the gas supply channel, and is placed so as to be closer to the base end side than the leading end surface (44) on which the observation window (46) is provided. Accordingly, it is possible to prevent bubbles generated near the gas jetting port (54, 64, 68) from blocking the field of view of the observation window (46) when a constant-pressure gas is supplied via an opening formed on a leading end surface (44) of a flexible endoscope (10), to thereby secure the field of view.

    摘要： Provided is an attachment for an endoscope (40), the attachment being attached to a leading end part of the endoscope having a leading end surface on which an observation window (46) for observing an inside of a subject's body and a first opening (50) for jetting a constant-pressure supplied gas are formed, the attachment including: a second opening (66, 76) provided at a position separate from the leading end surface; a pipe conduit (62, 72) that communicates the first opening and the second opening with each other so as to jet the constant-pressure supplied gas from the second opening; and a region separating member (60, 70) that separates a jetting region of the constant-pressure supplied gas jetted from the second opening from a region of view of the observation window. Accordingly, it is possible to prevent generated bubbles from blocking the field of view of an observation window when a constant-pressure gas is supplied via an opening of a treatment tool channel formed on a leading end surface of a flexible endoscope, to thereby secure the field of view.

    摘要： An anastomotic instrument (4) includes first and second units (21, 22). The first unit (21) is attached to a distal end portion (5a) of an insert section (5) of an endoscope (3), and has a self-propellable apparatus (30) and an anvil (31). The second unit (22) is attached behind the first unit (21), and has a cartridge (71) and a balloon (72). The insert section (5) with the anastomotic instrument (4) is inserted into the alimentary canal (90). In the alimentary canal (90), fluid is sucked out from space enclosed by the first and second unit (21, 22) through a suction port (83a) provided in the cartridge (71), to bring the space into negative pressure. While the alimentary canal (90) is shrunk in the space, the second unit (22) is shifted relative to the first unit (21). In a state where the shrunk alimentary canal (90) is caught between the first and second units (21, 22), a cutter (80) resects living body tissue (91), and staples (79) are struck to join edges of an incision of the alimentary canal (90).

    摘要： Provided is an optical connector including: an SI-type light source side optical fiber which is disposed on the light source side and an SI-type light receiving side optical fiber which is disposed on the light receiving side. Both optical fibers are optically coupled to each other by disposing an end surface of the light source side optical fiber and an end surface of the light receiving side optical fiber so as to face each other. The light source side optical fiber and the receiving side optical fiber are attachable to and detachable from each other. The light source side optical fiber includes a taper portion in which the diameter of the core portion increases toward the end surface of the light source side optical fiber.
