Abstract: An endoscopic device includes a longitudinal member, a pair of jaws installed at a distal end of the longitudinal member and configured to be freely opened and closed, a first grasping member supported by a first jaw of the pair of jaws, a second grasping member supported by a second jaw of the pair of jaws, the second body having a wire shape, flexibility, and being curved in a loop shape, a long operating transmission member having a distal end portion connected to the pair of jaws and installed to advance and retreat along a longitudinal axis of the longitudinal member, and an open-close operating portion installed at a proximal end portion of the operating transmission member and configured to be manipulated to open and close the pair of jaws.

Abstract: A medical device includes a long shaft member, a curved portion configured to be curved, a support member that is configured to be deformed along a curved shape of the curved portion, a guide member that extends from a distal end of the curved portion, and a linear member that includes a connection portion connected to the guide member, the linear member being inserted into the support member, and that pulls the guide member in accordance with a change of the curved shape. A central axis of the guide member is positioned apart from the central axis of the support member. The linear member which protrudes from the support member is inclined with respect to a longitudinal axis of the guide member and is connected to the connection portion.

Abstract: An endoscope auxiliary tool includes a first support section which is formed to extend along a longitudinal axis, a second support section which is formed substantially in parallel to the longitudinal axis of the first support section, a first protrusion section and a second protrusion section which are formed at distal end sections of the first support section and the second support section, respectively, and disposed more distal than the distal end section of the endoscope to sandwich an axis of a channel having an opening at the distal end section of the endoscope, and a positioning section which is configured to position the first protrusion section and the second protrusion section with respect to the distal end section of the endoscope such that the first support section and the second support section are inclined to the axis of the channel.

Abstract: An endoscope holding device includes an insertion part that is long and holds the distal end part of an endoscope so as to freely protrude and retract; a distal end face that specifies a protruding direction of the endoscope, and is formed at the distal end of the insertion part, a displacement part which has a displacement face that is curved from the distal end toward a proximal end and provided at a position apart from the distal end face in order to displace living body tissue in front of the insertion part to secure a space for operating the distal end part of the endoscope protruded from the distal end face to curve; and a fixing portion that fixes the displacement part and the insertion part such that the distal end side of the displacement face intersects a direction orthogonal to the distal end face.

Abstract: The present application relates to a biological tissue transfer method for transferring a biological target tissue within the body, the method comprising: (a) attaching part of a first traction member to a first position which is different from a connecting position at which the target tissue is connected to other biological tissue; (b) attaching part of a second traction member to a second position which serves as the apex of a triangle formed together with the connecting position and the first position that surrounds the target site; (c) extending the first traction member in the direction from the connecting position to the first position, and extending the second traction member in the direction from the connecting position to the second position; and (d) transferring the target tissue within the body by applying traction on the first traction member and the second traction member respectively.

Abstract: A method of treating a lesion of a tubular organ that communicates with a natural orifice of a subject is provided. In the method, a channel of the tubular organ is closed or substantially closed at a desired first position on a far side of the lesion. Then, the channel is closed or substantially closed at a second position near the orifice, i.e. on a near side of the lesion. Then, the tubular organ is linearized by charging a fluid into a closed space formed between the first and second positions by bringing the tubular organ into a closed or substantially closed state. Treatment tools are inserted into the linearized closed space to treat the lesion.

Abstract: An organ displacing method implemented for performing a procedure in a patient's body cavity, the method includes a gravitational movement step in which the body position of the patient is changed, whereby surrounding organs adjacent to a hollow organ are moved in a primary direction by gravity; and a non-gravitational movement step in which, by using a medical instrument inserted into the hollow organ, the hollow organ is moved in a secondary direction where the hollow organ is separated from the surrounding organs.
