The present invention has an introducing tube capable of being inserted into a living body cavity, a manipulating wire movably inserted into this introducing tube, at least two or more clips, and a ligating wire causing the clip and the manipulating wire to be engaged with each other wherein, when the clip is ligated, a tensile stress of the manipulating wire is always applied only to the clip located at the most distal end.

Apparatus for ligating living tissues

An intra-subject observation system includes a first liquid inserted into a desired organ of a subject; and a second liquid inserted into the organ without being mixed with the first liquid due to a specific gravity lighter than that of the first liquid. The system also includes a capsule medical apparatus inserted into the organ with an intermediate specific gravity between the specific gravity of the first liquid and that of the second liquid to acquire intra-subject information, which is output out of the subject by radio.

Intra-subject observation system and intra-subject observation method

This invention includes a clip having arms which grip living tissue, a press tube serving as a clamping member which is fitted and mounted on the clip to close the arms of the clip, a coupling member which can be inserted into the press tube and engages with the clip, and projections serving as lock portions which hold the arms of the clip in a closed state when the clip engages with the press tube.

Living tissue ligation device

An endoscopic instrument used to form an artificial valve for treating gastroesophageal reflux disease (GERD).

Endoscopic instruments

A holding member has an opening portion which opens to an distal end. The opening portion, the distal end of an endoscope and a holding member define a treatment space. A clamping member can project and retreat from and into the opening portion through the treatment space. The puncture member can move in the treatment space, in a direction that intersects with the longitudinal direction of the endoscope.

Endoscopic suture apparatus

An endoscope for treatment suitable to the treatment in a body cavity comprises an elongated soft observing optical unit having at least an observing optical system; and a unit inserting tool having a unit inserting channel in which the observing optical unit is inserted and a treatment tool inserting channel in which a treatment tool is inserted. The unit inserting channel of the unit inserting tool has a branching portion at which the unit inserting channel is branched into a first inserting channel and a second inserting channel. An observing window which is arranged at the end opening of the first inserting channel is provided in a surface at the distal-end and an observing window which is arranged at the end opening of the second inserting channel is provided in a surface at the halfway portion. The unit inserting tool comprises an optical unit guiding port for guiding the observing optical unit and at least one treatment tool lead-in port in which a treatment tool is inserted at the proximal end portion and a treatment tool lead-out port which is communicated with the treatment tool inserting channel that extends from the treatment tool lead-in port at least in one of the surface at the distal-end and the surface at the halfway portion.

Endoscope suitable to body cavity

An endoscope system in accordance with the present invention comprises a plurality of endoscope modules having different treatment instruments mounted therein, an endoscope to which the endoscope modules can be attached, and a coupling member fixed to the distal part of an insertion unit of the endoscope and used to make the plurality of endoscope modules freely exchangeable. The plurality of endoscope modules having the different treatment instruments mounted therein are freely exchangeable to be coupled to the distal part of the insertion unit of the endoscope.

Endoscope system

In a suction control unit used with an endoscope having a channel, a tubular main body has a suction port in the side wall and a bore and in the bore, an inner tube with a through hole communicating with the channel of the endoscope is installed. A sliding tube is located slidably in the axial direction between the main body and the inner tube. The proximal end portion of an operating lever is secured at an upper position of the sliding the tube while the distal end portion extends outside the main body. This suction control unit is equipped with passage switching unit to connect the suction port with the endoscope channel or the outside of the main body through a relief port when the operating lever is operated.

Suction control unit for an endoscope

Disclosed is a construction of an endoscopic fluid changing device which, attached to an endoscope, regulates the flow of a fluid in a channel of the endoscope. The fluid changing device comprises a cylindrical casing having a suction port, in the side wall thereof, a channel pipe provided in the center of the casing, and having an opening at the upper end portion thereof, the lower end portion of the channel pipe being connected to an instrument channel, extending to the distal end portion of the endoscope, a cap member covering the opening of the channel pipe, a piston disposed between the casing and the channel pipe, and capable of vertical motion, a spring for urging the piston upward, first valve device provided at the upper portion of the piston, and adapted to open or close a first passage as the piston is operated, the first passage extending from the suction port to the outside of the casing, and second valve device provided at the lower portion of the piston, and adapted to close or open a second passage, in contrast with the first passage, as the piston is operated, the second passage extending from the suction port to the instrument channel.
