Benefits of technology

[0037]According to the gastric therapy system and the method of the present invention for cerclaging the gastric wall, therapeutic operations for cerclaging a part of the stomach can be conducted smoothly and accurately irrespective of the skill of a surgeon.

Problems solved by technology

The linking point is difficult to be identified in the above therapeutic operations, since an endoscopic observation of inside the stomach provides a continuous view of the gastric wall.
Therefore, a surgeon who conducts such an peroral therapeutic operation is required for considerable skill.

first embodiment

[0096]As illustrated in FIG. 1, a therapy system 1A according to the present embodiment has an endoscope 2; an overtube 3 passed through the endoscope 2; and a cerclage instrument 4 which serves as a therapy section for cerclaging a part of a gastric wall.

[0097]The endoscope 2 has a maneuvering section 11 that is maneuvered by a surgeon; and a long length of elastic insertion section 12. The insertion section 12 extending from the maneuvering section 11 serves as a loop-forming member that forms a loop in a stomach ST. Disposed at the punching instrument of the insertion section 12 are an observation device and a lighting device that are not shown in the drawing. A lumen undertaking air-suction, water-supply, or allowing an instrument like forceps to pass therethrough is formed from the distal end of the insertion section 12 to the maneuvering section 11 in the insertion section 12. Manipulating a knob 13 disposed on the maneuvering section 11 allows the distal end of the insertion ...

second embodiment

[0121]As illustrated in FIG. 12, a therapy system 1B in a second embodiment has an insertion section 72 that serves as a loop-forming member; and a cerclage instrument 4 that serves as a therapy section. The cerclage instrument 4 is detachably attached to the distal end of the insertion section 72. The insertion section 72 having elasticity extends from a manipulation section 75 of the cerclage instrument 4. In addition, the insertion section 72 is operative as a loop-forming member since the insertion section 72 passed through the overtube 3 has a length that enables to form a loop in the stomach ST. If necessary, the distal end of the insertion section 72 may be capable of bending. Specific configuration that enables the bending manipulation may be an insertion section 72 manufactured from a flexible material, or an assembly of corrugated tubes that is to be drawn by a wire. As illustrated in FIG. 13, each component 73a used in the corrugated tubes may have a cylindrical cross-sec...

third embodiment

[0125]As illustrated in FIG. 15, a cerclage instrument 4 is attached to the distal end of an overtube 82 in a therapy system 1C according to a third embodiment. The overtube 82 has an elastic cylindrical main unit 83; and a manipulation section 22 (see FIG. 1) that is manipulated by the surgeon. The main unit 83 extending from the manipulation section 22 serves as a loop-forming member that forms a loop in a stomach ST. A Solenoid 26 serving as a link apparatus of the overtube 82 is attached onto a predetermined position of a lateral surface of the distal end section 21A of the main unit 83. In addition, a plurality of suction ports 84 are formed on a lateral surface of the main unit 83 with intervals along a longitudinal direction of the main unit 83. Air can be suctioned from the stomach ST through the suction ports 84. The main unit 83 may be produced by resin material or super elastic alloy, etc. Alternatively, the main unit 83 may be produced to have a corrugated tube construct...

Abstract

This gastric therapy system includes a loop-forming member that forms a loop along a lesser-curvature-line and a greater-curvature-line in a stomach; a guide member that introduces the loop-forming member into the stomach; and a therapy section that cerclages a part of the gastric wall after looping the loop-forming member.

Description

[0001]The present application is based on U.S. Patent Application No. 60 / 877,517, filed Dec. 28, 2006, and U.S. Patent Application No. 60 / 898,309, filed Jan. 30, 2007, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a natural orifice and gastric therapy system and relates to a method for suturing a gastric wall.[0004]2. Background Art[0005]In some therapeutic operations, a part of a stomach is cerclaged for the purpose of preventing obesity, etc. Peroral therapeutic operations are conducted while observing inside of a stomach by an endoscope passed through an overtube inserted from a mouth of a patient (see, for example, U.S. Pat. No. 7,083,629, U.S. Publication No. 2005 / 0251158, WO2006 / 055804, and WO2006 / 112849). These therapeutic operations use a cerclage therapeutic instrument passed through a job channel of the endoscope, e.g., an anterior wall and a posterior gastric wall...
