  • Publication number: 20030045891
    Abstract: An endoscopic suturing instrument is equipped with a needle mounted at the distal end of the suturing instrument for the purpose of living-tissue punctures. An engaging means is provided at least at the distal end of the needle for the purpose of connecting the thread while allowing it to move freely, and it is equipped with a needle-driving means to drive the needle. A loop-creating means, used to create a first loop in the thread, is provided for the suturing instrument. The first loop is formed by loosening the thread connected to the engaging means. A catching means to be inserted through the first loop to catch the thread is provided at the distal end of the suturing instrument. The thread caught by the catching means can be moved freely. The needle-driving means and the catching means are integrated into one.
