Ligature and suture device for medical application, ligature and suture system for medical application, and ligaturing and suturing method for medical application
First Claim
1. A ligature and suture device for medical application that ligatures or sutures biomedical tissue that has been suctioned by a suction device using a suturing member, the ligature and suture device comprising:
- an insertion portion having a lumen into which an endoscope can be inserted, and a distal end portion that is connected to the lumen and in which at least one side aperture is provided;
at least one hollow needle that is able to support inside itself the suturing member, and that is placed inside the insertion portion such that a tip of the hollow needle is able to move between a first position, which is on a base end side of the side aperture, and a second position, which is on a distal end side of the side aperture;
an operating section that performs an operation to move the needle; and
at least one pledget that can be penetrated by the needle, and that is placed in a vicinity of the distal end of the side aperture so as to be freely removable from the distal end portion.

Abstract
A ligature and suture device for medical application that ligatures or sutures biomedical tissue that has been suctioned by a suction device using a suturing member. The ligature and suture device includes an insertion portion having a lumen into which an endoscope can be inserted, and a distal end portion that is connected to the lumen and in which at least one side aperture is provided, at least one hollow needle that is able to support inside itself the suturing member, and that is placed inside the insertion portion such that a tip of the hollow needle is able to move between a first position, which is on a base end side of the side aperture, and a second position, which is on a distal end side of the side aperture, an operating section that performs an operation to move the needle, and at least one pledget that can be penetrated by the needle, and that is placed in a vicinity of the distal end of the side aperture so as to be freely removable from the distal end portion.

20. A ligature and suture method for medical application that ligatures or sutures biomedical tissue that has been suctioned by a suction device using a suturing member, the ligature and suture method comprising:
-
a suction process in which an endoscope is inserted into an insertion portion having a lumen into which the endoscope can be inserted, and a distal end portion that is connected to the lumen and in which at least one side aperture is provided, and the biomedical tissue is suctioned from the side aperture into the distal end portion;
an insertion process in which at least one hollow needle that is able to support inside itself the suturing member, and that is placed inside the insertion portion such that a tip of the hollow needle is able to at least move between a first position, which is on a base end side of the side aperture, and a second position, which is on a distal end side of the side aperture is inserted into the biomedical tissue and into at least one pledget that is placed between the distal end of the side aperture and the second position on a movement path of the needle so as to be freely removable from the distal end portion;
a process in which the suturing member is pushed out from inside the needle to the distal side of the pledget; and
a process in which suturing or ligaturing is performed using the suturing member by withdrawing the needle from the biomedical tissue.
