摘要:
A ligature and suture device for medical application that ligatures or sutures biomedical tissue that has been suctioned by a suction device using a suturing member. The ligature and suture device includes an insertion portion having a lumen into which an endoscope can be inserted, and a distal end portion that is connected to the lumen and in which at least one side aperture is provided, at least one hollow needle that is able to support inside itself the suturing member, and that is placed inside the insertion portion such that a tip of the hollow needle is able to move between a first position, which is on a base end side of the side aperture, and a second position, which is on a distal end side of the side aperture, an operating section that performs an operation to move the needle, and at least one pledget that can be penetrated by the needle, and that is placed in a vicinity of the distal end of the side aperture so as to be freely removable from the distal end portion.

A tissue-piercing device includes two piercing members, and an operation section to which a proximal end of each of the piercing members is connected. Each of the piercing members includes a flexible outer sheath, a slidable inner sheath which is slidably inserted in the outer sheath, and a slidable needle which is inserted in the inner sheath. A switch portion is provided for switching between an operation mode in which a piercing action by the two piercing members is performed in a single operation, and an operation mode in which piercing actions by the two piercing members are performed in respective separate operations. The switch portion includes a sheath-coupling member to couple and decouple the two slidable inner sheaths. The switch portion may include a needle-coupling member to couple and decouple the two slidable needles.

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.
