Abstract

A suture ligating device used in a endoscopic surgery which can reliably transfer a knot of a suture formed outside a human body to inner tissues to be ligated inside the human body without causing a separation of the knot from the suture ligating device. The suture ligating device includes a manipulation portion, first and second rod members provided at the manipulation portion and making a relative movement in response to an operation of the manipulation portion, first and second top end members provided at an end of the first rod member, concaves formed at the ends of the first and second top end members, and the third top end member provided at an end of the second rod member to perform an open and close movement in response to the relative movement of the first and second rod members.

Claims20

Dependent claims

A suture ligating device, comprising:

a manipulation portion;
first and second rod members for conducting a relative movement to each other in response to an operation of said manipulation portion;
first and second top end members provided at an end of said first rod member, each of said first and second top end members having a U-shape and being parallel with each other;
and
a third top end member connected to the second rod member and rotatably moves relative to said first and second top end members for forming an open or closed space in accordance with the relative movement of the first and second rod members;
wherein said U-shape of said first and second top end members forms two concaves opening in a top end direction, each of said two concaves is separated from each other by a predetermined distance, and the third top end member enters in a space having said predetermined distance between the first and second top end members or retreats from said space at a position ahead of a bottom of each of the concaves of the first and second top end members.

3 more elements

A suture ligating device, comprising:

a manipulation portion;
first and second slender members for conducting a relative movement to each other in response to an operation of said manipulation portion;
first and second top end members provided at an end of said first slender member;
and
a third top end member connected to the second slender member and moves in a space provided between the first and second top end members in accordance with the relative movement of the first and second slender members;
wherein the first and second top end members are provided with concaves opening in a top end direction, the first and second top end members are separated to each other by a predetermined distance, the distance of which being variable in response to the relative movement of first and second slender members, and the third top end member enters in the space between the first and second top end members or retreats therefrom at a position ahead of a bottom of the concaves of the first and second top end members.
