Abstract: In a disclosed method for inserting an endoscopic device, in a state in which a guide wire is inserted through an opening of a hollow organ of a subject, the guide wire is indwelt in the hollow organ. Next, a flexible endoscope is made to approach the opening of the hollow organ. Next, inside of the body of the subject, an endoscopic device that projects from the tip of a channel of the endoscope slidably engages with the guide wire. Next, the endoscopic device is inserted into the hollow organ through the opening, along the guide wire. The guide wire that is indwelt once is subsequently used as a guide for second and subsequent insertions of endoscopic devices.

Abstract: An endoscopic treatment method includes: inserting an endoscope into a digestive tract; forming a damaged area in at least a portion of the digestive tract along a circumferential direction by performing cauterizing while keeping a mucosal layer by observing with the endoscope; and forming an incomplete stenosis in the digestive tract, while restoring the damaged area, wherein the damaged area is formed by causing damage to a mucosal base layer, the mucosal base layer having an interface that contacts a submucosal layer.

Abstract: A needle holder includes a sheath, a grasper capable of grasping a target object, an operation portion capable of opening and closing the grasper, and an operation wire. The operation portion includes a main body, a slider, and an elastic member that is elastically deformable depending on an opening and closing position of the grasper. The slider is connected to the grasper via the operation wire. The grasper can release grasping of the target object and can grasp the target object with a first grasping force in response to an operation of moving the slider against a restoring force of the elastic member. The grasper can grasp the target object with a second grasping force smaller than the first grasping force when the restoring force of the elastic member and tension of the operation wire are balanced.

Abstract: In a method for inserting an endoscopic device, a guide wire is punctured into a subject from outside the body. A tip portion of the wire is inserted into a first hollow organ. A tip-side portion of the inserted wire is projected into a lumen of a second hollow organ that communicates with the first via an opening, from the opening. An endoscopic device is inserted through a flexible endoscope and pushed into the second hollow organ. A tip portion of the device is locked onto the tip-side portion of the wire projecting into the second hollow organ. A portion of the wire outside the body of the subject is held and is tugged outside of the body. The tip portion of the device is thus pulled into the first hollow organ from the second, via the opening. Therefore, the endoscopic device can be led to the first hollow organ.
