Abstract:
An endoscope system has an endoscope; an attachment for the endoscope, having a non-circular irregularly shaped hole that communicates with an opening of a channel of the endoscope and attached to a forward end of an insertion section of the endoscope; and a treatment instrument for the endoscope, having a flexible tube and a treatment section. An extension/retraction section having a non-circular cross section corresponding to the shape of an opening of the irregularly shaped holes is provided at a forward end of the flexible tube, and the irregularly shaped hole restricts rotation of the flexible tube. Further, the treatment section has directivity about its axis relative to the flexible tube and its rotation is restricted.
Abstract:
Basket type grasping forceps include a sheath, a main body section, and a manipulation section, the main body section includes a basket section and a manipulation wire, the basket section includes a plurality of basket wires and a distal fixing member fixed to the plurality of basket wires, and the distal fixing member has a wire-fixing section to which a first wire serving which is at least one of the plurality of basket wires is fixed, and a high-strength fixing section to which a second wire which is at least another one of the plurality of basket wires is fixed more strongly than a fixing strength of the first wire in the wire-fixing section.
Abstract:
A movable body (16) is inserted retractably into a flexible tube (12) being able to be inserted into a channel of an endoscope. A treatment unit (18) has directivity projectable and retractable with respect to a far end portion of the flexible tube (12) by the movable body (16). The flexible tube (12) is raised by a treatment apparatus raiser provided on the channel of the endoscope. In this time, a direction control member (44) is raised together with the flexible tube by the treatment apparatus raiser, and the direction of the treatment unit (18) is adjusted.
Abstract:
An endoscope treatment system, comprising a device for inserting, extracting, and rotating a treatment tool capable of performing the moving operation of the treatment tool inserted into the channel of the endoscope along the advancing/retracting directions and the rotating operation of the treatment tool around the axis thereof.
Abstract:
A binding part of a basket-type grasping forceps includes: a first binding part (9) to which proximal ends of first wires (5a) that are some of a plurality of basket wires (5) are fixed; and a second binding part (11) to which proximal ends of second wires (5b) not connected to the first binding part (9) among the plurality of basket wires (5) are fixed, which is engaged with the first binding part (9) to be separable from the first binding part (9), is containable inside a sheath (2) along with the first binding part (9) in a state in which the second binding part (11) is engaged with the first binding part (9), and is held by an inner surface of the sheath (2) to be inseparable from the first binding part (9) in the sheath (2).
Abstract:
In a discharge mechanism of basket-type gripping forceps according to the present invention, a support member can advance and retract relative to a plurality of basket wires, the position of the support member can be fixed, and an object inside a basket part is discharged to the outside of the basket part from a portion of the basket part proximal to the basket wires by movement of the support member and the basket part relative to each other.
Abstract:
An endoscopic treatment system 1 of the present invention includes an overtube 2 that is inserted into the body of a patient. An endoscope 7 and a suturing device 8 are inserted into the overtube 2. The overtube 2 has a long and flexible tube main body 3, and a chamber 4 is provided at the distal end of the tube main body 3. The chamber 4 has a lateral hole 10 formed on the lateral surface thereof. The width of the lateral hole 10 is set such that a lesion can be drawn into the lateral hole 10 while preventing other organs on the periphery of the lesion from being drawn into the lateral hole 10.
