  • Patent number: 11284904
    Abstract: A clip treatment tool includes a clip body that has two clip-pieces, the two clip-pieces each having a body-portion and an arm-portion, the body-portion having a fixing-hole formed on a proximal end side and a movement hole formed on a distal end side relative to the fixing-hole, the movement hole extending so as to be inclined from a side part in a width direction of the body-portion on the proximal end side toward a middle in the width direction of the body-portion on the distal end side; a container tube that contains the body-portions of the two clip-pieces therein; a stopper that extends through the fixing-holes of the two clip-pieces and that is attached to the clip body; and a fixing pin that extends through the movement holes of the two clip-pieces and whose both end portions are fixed to positions in the container tube that face each other.

  • Patent number: 11141167
    Abstract: A clip treatment tool includes a clip body that has two arm portions and a folded portion, the folded portion connecting proximal end parts of the two arm portions; a pressing tube that allows the clip body to be contained therein in accordance with movement of the clip body from a distal end side toward a proximal end side; a coupling member that couples the clip body and an operation wire to each other; and an urging member that urges the coupling member relative to the pressing tube from the proximal end side toward the distal end side. The pressing tube has a latched portion, and the coupling member has a latch portion. In accordance with movement of the operation wire from the distal end side toward the proximal end side, the latch portion is latched to the latched portion, and the coupling member is locked to the pressing tube.

  • Patent number: 11141166
    Abstract: In a clip treatment tool, a clip locking part brings arms into a closed state after the arms are brought into a closed state in a state where distal ends of the arms of the clip brought into an open state is pressed against a treatment part and the treatment part is ligated to the distal ends of the arms brought into the closed state. After the clip in which the arms are locked to the closed state is separated from the sheath part and indwelled in the treatment part, the clip removal part is indwelled in the treatment part, the locking of the arms locked to the closed state is released, the arms are brought into the open state as the locking is released, and the clip removed from the treatment part is maintained and taken out.

  • Patent number: 11013517
    Abstract: A clip treatment tool includes: a clip body that has two arm portions and a folded portion, the two arm portions, the folded portion connecting proximal end parts of the two arm portions; a tightening ring that functions to close the two arm portions in accordance with movement of the clip body from a distal end side toward a proximal end side; a pressing tube that has at least one opening formed in an outer surface thereof, and that allows the clip body to be contained therein in accordance with the movement of the clip body; and a coupling member that has a distal end part to which the folded portion is removably connected and a proximal end part to which a distal end part of an operation wire is fixed, the coupling member coupling the clip body and the operation wire to each other.

  • Patent number: 4338170
    Abstract: A cis-trans isomerization of a cis-.beta.-.gamma.-unsaturated alcohol or its ester having the formula ##STR1## wherein R.sub.1 represents hydrogen atom or a C.sub.1 -C.sub.5 alkyl group; X represents hydrogen atom or ##STR2## and R.sub.2 represents a hydrocarbon moiety or a hydroxyhydrocarbon moiety; R.sub.3 represents hydrogen atom or a hydrocarbon moiety into a transform, in the presence of a mercaptan as a catalyst, is provided. It can be also attained in the presence of a mercaptan and/or a disulfide as a catalyst in an inert gas environment with an initiator. It can be also attained in the presence of a mercaptan under an irradiation, if desired with a small amount of an initiator.
