Patent number: 11730343Abstract: An endoscope treatment tool includes: a cylindrical cap attached to an outer side of a distal-end section of an endoscope and having first and second radial directions intersecting each other; a treatment tool supported at an outer side of the cap in the first radial direction to be movable in the longitudinal direction; and a linear flexible coupling member coupling the treatment tool with the cap such that the grasper reaches a position where the grasper protrudes from a distal end of the cap. A swing section of the coupling member couples the cap with the treatment tool to allow relative movement in the second radial direction, and, in response to pressed forward in the longitudinal direction by the treatment tool, swings about a swing axis extending in the second radial direction while generating a tensile force and bending the treatment tool inward in the first radial direction.Type: GrantFiled: August 11, 2020Date of Patent: August 22, 2023Assignees: OLYMPUS CORPORATIONInventors: Naohisa Yahagi, Yasuhiro Tabuchi, Yuya Hidaka

Patent number: 11564557Abstract: The disclosed technology is directed to a medical instrument for endoscopic use. The medical instrument comprises an elongated open ended over tube configured to receive an endoscope in a direction along a longitudinal central axis of the over tube. The endoscope travels retractably from a distal end of the over tube. A tube is disposed concentrically outwardly of the over tube so that a treatment tool is inserted through the tube and is projected forwardly with respect to the over tube from a distal end of the tube. A balloon is disposed on an external surface of the over tube and is expandable outwardly in a radial direction of the over tube.Type: GrantFiled: December 11, 2019Date of Patent: January 31, 2023Assignee: OLYMPUS CORPORATIONInventors: Yukio Sato, Yasuhiro Tabuchi, Yuya Hidaka

Patent number: 11369407Abstract: The disclosed technology is directed to a method of operating a treatment tool for excising a lesioned portion of a body tissue. The method comprises applying a treatment tool to the lesioned portion. The treatment tool includes an elongated sheath having a snare wire disposed therein. The snare wire is configured to be movable forward or backward along a longitudinal direction. Next, forming the snare wire into a loop and tilting the loop in a plane transverse to the longitudinal axis of the elongated sheath with a force tending to push a snare wire portion out of a distal-end opening of the elongated sheath. And finally, placing the loop around the lesioned portion of the body tissue to excise the lesioned portion in a state in which the snare wire positioned transverse to the lesioned portion.Type: GrantFiled: December 19, 2019Date of Patent: June 28, 2022Assignee: OLYMPUS CORPORATIONInventors: Yasuhiro Tabuchi, Yuya Hidaka
