Tissue ligating device

摘要

A tissue ligating device to which a suture is attached and which ligates a tissue includes a suture fix member which is attached to the suture, and which includes a housing part which one part of the suture can be hooked; and a hooked suture locking part configured to prevent the suture hooked in the housing part from disengaging from the housing part.

主权项

1. A tissue ligating device comprising:
a suture fix member comprising:
a connection part that defines an insertion opening through which a first part of a suture is inserted and attached;an engagement part comprising:
a primary arm part extending from the connection part; anda first secondary arm part extending from the primary arm part,wherein the primary arm part and the first secondary arm part define a first housing space through which a second part of the suture is selectively inserted to be engaged by the engagement part,wherein the primary arm part and the first secondary arm part are configured to have:
a first configuration in which a first surface point on the primary arm part is separated from a second surface point on the first secondary arm part opposing the first surface point such that the first housing space is an open space, anda second configuration in which the first secondary arm part is deformed to bring the second surface point in contact with the first surface point such that the first housing space is a closed space, wherein the first secondary arm part is configured to be deformed to maintain the second configuration,wherein a closed end of the first housing space is formed by a connection point between the primary arm part and the first secondary arm part, andwherein in the first configuration, the primary arm part and the first secondary arm part are arranged such that the first housing space is an elongated space that extends along an engagement/disengagement axis away from the closed end of the first housing space toward an open end of the first housing space; anda protrusion that opposes the connection point between the primary arm part and the first secondary arm part, wherein the protrusion intersects the engagement/disengagement axis.
