摘要:
A fluorescent endoscopy apparatus includes an endoscope insertion unit that is inserted into a body cavity and that guides excitation light to illuminate a region to be observed, and an imaging unit that images a fluorescent image by receiving fluorescence that has been output from the region to be observed by illumination with the excitation light and guided by the endoscope insertion unit. Further, the fluorescent endoscopy apparatus includes a facial information detection unit that detects facial information about a person in an imaging image that has been imaged by the imaging unit by receiving light guided by the endoscope insertion unit, and an interlock unit that prohibits illumination with the excitation light when the facial information detection unit has detected the facial information.

To prevent excitation light output from an output end of a light guiding portion causing damage to the eye when the light guiding portion which guides the special light output from a light source is detached from the insertion portion. Provided is an endoscope apparatus including: an insertion portion that is inserted into a body so as to irradiate special light to a subject observation portion inside the body and receives light output from the subject observation portion by the irradiation of the special light; and a light guiding portion that is optically connected to the insertion portion and guides the special light output from a light source to the insertion portion, wherein an output end for the special light in the light guiding portion is equipped with a diffusing portion that diffuses the special light guided by the light guiding portion.

A perforation suturing method has the steps of: inserting a needle into a wall of a hollow organ at a periphery of the perforation formed in the hollow organ, and piercing the wall; withdrawing the needle from the wall after delivery of an anchor attaching suture thread from the needle, and having the suture thread transit the wall; and tightening the suture thread so that the mated insertion points at the time of insertion of the needle into the wall approximately coincide after having the needle pierce the wall at the periphery of the perforation a plurality of times, and making surfaces of the wall where the insertion points are formed coincide with each other.

A self-propelled unit for an endoscope having a section of an elongated tube for entry in a body cavity is provided. A first ring sleeve is mounted around the elongated tube on a distal side in a rotatable manner. An endless track device is disposed around the first ring sleeve, having an outer annular surface, for turning around in contact with a wall of the body cavity, for propulsion in an axial direction of the elongated tube. A combination of a worm drive and an engagement roller is disposed on the first ring sleeve, for moving the endless track device.A movable plate is contained in the endless track device, movable between open and closed positions, for coming farther from the elongated tube at least locally when in the open position than when in the closed position, in order to shift the endless track device away from the elongated tube.

A ligature device for medical treatment has an operating device that has a ligature tool for medical treatment fitted onto a distal end portion thereof. The operating device is provided with a cutting member that is able to move freely backwards and forwards and is used to cut a ligature wire of the ligature tool for medical treatment. A distal end side of the cutting member has an inclined end portion that is inclined relative to the direction of forward and backward movement, and a blade portion is provided in this inclined end portion.

A guide assembly for an endoscope having an elongated tube includes a first inner sleeve, a first outer sleeve, an endless track device, engagement rollers, a second inner sleeve and idler rollers. The endless track device has an annular surface, is supported around the first outer sleeve, for endlessly moving in an axial direction of the elongated tube in contact with a wall of the body cavity, for propulsion of the elongated tube. A setting device as second outer sleeve is shiftable between a set position and a release position, for pressing the idler roller on the engagement roller when in the set position, to nip the endless track device therewith, and for retracting the idler roller from the engagement roller in an outward direction when in the release position, to facilitate removal of the endless track device from the first outer sleeve.
