A suture device includes: a longitudinal member extended along a longitudinal axis; a first grasping member and a second grasping member provided at a distal portion of the longitudinal member and configured to enable opening-closing movement; an opening-closing mechanism configured to open and close the first grasping member and the second grasping member; a delivery mechanism configured to deliver a distal member between the first grasping member and the second grasping member, the distal member to which a suture thread is fixed; and an engage portion supported by one of the first grasping member and the second grasping member so as to protrude from a distal end of at least one of the first grasping member and the second grasping member and having an engaging-surface capable of engaging the suture thread.

Suture device

This tissue fastening apparatus is a tissue fastener for clamping first biological tissue and second biological tissue so as to be in close contact with each other, including: a first tissue fixation portion, made of an elastic wire wound in a coil, that is locked on the first biological tissue; and a second tissue fixation portion, made of an elastic wire wound in a coil, that is locked on the second biological tissue, the second tissue fixation portion continuing into the first tissue fixation portion, in which when falling off first and second biological tissue necrotized by being clamped between the first tissue fixation portion and the second tissue fixation portion, the tissue fastener moves only from the second tissue fixation portion to the first tissue fixation portion side and falls off.

Method of forming through hole

A closure device includes a protruding member that is detachably provided at a distal end of a longitudinal member; a pair of grasping members that are turnable with respect to the protruding member; first and second linear members that are connected to the pair of grasping members; and a holding portion that has an action portion for applying a force in a direction in which the pair of grasping members approach the protruding member and is detachably provided at a distal end of the longitudinal member.

Closure device

A tissue fastening apparatus related to the present invention includes; a tissue fastening tool formed of a wire wound into a coil shape provided with a first tissue fixing section which is hooked onto a first biological tissue and a second tissue fixing section which is hooked onto a second biological tissue; a tubular puncturing tool which extends a tissue fastening tool and accommodates the stretched tissue fastening tool inside of the puncturing tool; a fastening tool pusher in which the distal end thereof is inserted into the puncturing tool and dispenses the tissue fastening tool inserted into the puncturing tool from a distal end of the puncturing tool when the fastening tool pusher advances; and a rotating mechanism to rotate the puncturing tool when the fastening tool pusher advances.

Tissue fastening method

A thread-fixing tool includes a first member in which a lumen opened at an end surface through which a suture thread is inserted, and a communication path having a first end opened at the end surface and a second end in communication with an intermediate portion of the lumen are formed, and a second member having a shaft portion inserted into the communication path of the first member, and a pressing portion which is formed at a distal portion of the shaft portion and which is capable of deforming outwardly in a radial direction of the shaft portion, wherein the pressing portion is guided to the intermediate portion of the lumen through the communication path, and deformed in a direction crossing an insertion direction of the suture thread to push the suture thread against an inner wall of the lumen.
