Patent Images
1. An endoscopic suture apparatus comprising:
- an endoscope including an insertion section;
a clamping member which is configured to move in a longitudinal direction of the insertion section and to clamp living tissues;
a puncture member having a sharp end for penetrating the living tissues;
a drive member which is configured to move the puncture member in a direction that intersects with the longitudinal direction of the insertion section, and to cause the puncture member to penetrate the living tissues;
a suturing element which penetrates the living tissues by a penetration of the puncture member into the living tissues and is kept in the living tissues in a penetrating state to suture the living tissues; and
an engaging portion provided at an end portion of the suturing element, the engaging portion engaging with the living tissues to keep the suturing state of the suturing element in the living tissues.

Abstract
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.

12. An endoscopic suture apparatus comprising:
-
an endoscope including an insertion section, the insertion section having a distal end and a proximal end; at least one puncture member having a sharp tip for penetrating living tissues; a holding member which holds the puncture member so that the puncture member is movable in a direction intersecting with a longitudinal direction of the insertion section, and which has a distal end portion and a proximal end portion, the distal end portion having an opening, and the proximal portion being attached to the distal end portion of the endoscope; wherein the holding member forms a treatment space defined by the insertion section of the endoscope and the opening of the holding member, a clamping member which is configured to clamp the living tissues and then pulls the living tissues into the treatment space; wherein the clamping member outwardly projects from the opening through the treatment space so as to clamp the living tissues, and pulls the clamped living tissues into the treatment space so that the clamped living tissues are penetrated by the puncture member; a drive member which is configured to move the puncture member in the direction intersecting with the longitudinal direction of the insertion section; a suturing element which penetrates the living tissues by a penetration of the puncture element into the living tissues and is kept in the living tissues in a penetrating state to suture the living tissues; and an engaging portion provided at an end portion of the suturing element, the engaging portion engaging with the living tissues to keep the suturing state of the suturing element in the living tissues. - View Dependent Claims (13, 14, 15)
