  2. Description of the Related Art Conventionally, as this type of medical thread grasping / transferring device, there is a needle guide for a medical thread described in a prior art document. As shown in FIGS. 54 and 55, for example, the medical needle-with-thread introducer has a needle 12 to which a thread 11 is attached, and exerts a force on the needle 12 to at least a predetermined length from the tip 12a of the needle 12. A drive mechanism (mounting member 13) that passes the portion between tissues or between tissues, a holding portion 14 that holds a needle tip including the tip of the needle 12 that has passed between tissues or inside the tissue, and the needle tip is the holding portion 14 A pull-out mechanism 15 is configured to apply force to the needle 12 held by the needle 12 so as to pass the needle 12 between or between tissues. A handle 17 is provided on each side of the mounting member 13 and the shaft 16 of the extraction mechanism 15 (on the right side in FIG. 54). Further, a mounting portion 13a for detachably attaching the needle 12 is formed at the tip of the mounting member 13.

  The above-mentioned needle guide with a medical thread applies a force to the needle 12 to which the thread 11 is attached by a driving mechanism so that the tip of the needle 12 and the needle tip subsequent to the tip pass between tissues or in tissues. After that, the needle tip is held by the holding portion 14, and further, a force is applied to the needle 12 by the extraction mechanism 15 so that the needle 12 and the thread 11 can be extracted between the tissues or between the tissues. Yes.

  In order to ligate the blood vessel C using the above-described medical needle with needle, the following procedure is performed. First, as shown in FIG. 56, the practitioner opens the handle 17 and ligates the needle 12 and the holding part 14 with the needle 12 and the holding part 14 being separated via the mounting member 13 and the extraction mechanism 15.
