摘要:
This tissue fastening apparatus is a tissue fastener for clamping first biological tissue and second biological tissue so as to be in close contact with each other, including: a first tissue fixation portion, made of an elastic wire wound in a coil, that is locked on the first biological tissue; and a second tissue fixation portion, made of an elastic wire wound in a coil, that is locked on the second biological tissue, the second tissue fixation portion continuing into the first tissue fixation portion, in which when falling off the first and second biological tissue necrotized by being clamped between the first tissue fixation portion and the second tissue fixation portion, the tissue fastener moves only from the second tissue fixation portion to the first tissue fixation portion side and falls off.

An instrument (1; 61; 101; 201; 301; 301a; 500; 600) for an endoscope includes a first insertion portion (10; 71; 120; 206; 313) having an base end to which an operation section is connected; a first offset portion (11; 72; 130, 135; 205c; 312, 320) extending outward from an axis of the first insertion portion; a second insertion portion (12; 73; 140, 145; 205d; 325) having a base end joined to the first offset portion and an element extending parallel to the axis of the first insertion portion; a second offset portion (14; 74; 155, 160; 205e; 330, 341) which is joined to a head of the second insertion portion and reaches an extension of the axis of the first insertion portion; and a third insertion portion (16; 75; 165; 209; 343) which is joined to the second offset portion and has a portion arranged on an axis which is substantially the same as at least a part of the axis of the first insertion portion. An inner hole is formed through the first insertion portion, the first offset portion, the second insertion portion, the second offset portion, and the third insertion portion.

A manipulation mechanism of the present invention includes an oscillating body (91,92) which is disposed on a first imaginary plane (P2), where first and second imaginary planes (P2,P4) are parallel to each other with respect to a manipulation reference plane (P3); and a holding body (88) which is disposed on the second imaginary plane (P4) so as to regulate an oscillating locus of the oscillating body, wherein the oscillating body is provided with first and second convex portions (92a) which are spaced from each other and protrude toward the holding body, wherein the holding body is provided with first and second groove portions (88a) which respectively guide the first and second convex portions, and wherein the first and second groove portions are formed to be closer to each other in a direction away from the manipulation reference plane on one side of the manipulation reference plane from a point on the manipulation reference plane as a start point.
