Abstract
A method for closing a wound in a tubular organ using a suture thread attached to a suture needle. The method includes grasping a first part of the suture thread by a grasper inserted in the tubular organ after the suture thread has been passed through tissue surrounding the wound at a first position; moving the first part away from the first position by moving the grasper grasping the first part along a longitudinal axis of the grasper; grasping a second part of the suture thread located between the first part and the first position by the grasper; and moving the second part away from the first position by moving the grasper grasping the second part along the longitudinal axis of the grasper.
Claims8
A method for closing a wound in a tubular organ using a suture thread attached to a needle, the method comprising:
- passing the needle from a first peripheral tissue to a second peripheral tissue in this order, wherein the first peripheral tissue and the second peripheral tissue face each other across the wound, and arranging the suture so as to intersect the wound;
- grasping a first site in the suture between a proximal end of the needle and the second peripheral tissue, and moving the first site away from the second peripheral tissue;
- and
- releasing retention of the first site, grasping a second site in the suture between the first site and the second peripheral tissue, and moving the second site away from the second peripheral tissue, wherein, in moving the first site away from the second peripheral tissue, the first site is moved along a longitudinal axis of a grasper that grasps the first site.
