Description of the Related Art A medical ligating apparatus of this type is transendoscopic, that is, a medical ligating apparatus is introduced into a body through a treatment instrument insertion channel of an endoscope and ligates a tissue site in the body. This technique is disclosed in Japanese Utility Model Laid-Open No. 6-17712. The ligature includes a loop wire made of synthetic resin, and a loop portion of the loop wire ties up a lesion,
It is kept in the body for several days in that state. Then, the blood flow at the site of the diseased tissue is stopped by the binding, so that the tissue is necrotic and the diseased part falls off several days later. At this time, the ligature provided with the loop wire also falls off at the same time and is naturally discharged.

ることができる。As described above, according to the medical ligating apparatus of the present invention, since the transparent loop mounting aid is provided, when the ligating tool is mounted on the distal end of the sheath, the hook and the mounting device are used. Since it does not directly touch the loop, it is sanitary, and rubber gloves etc. are pulled into the sheath,
Safer because it doesn't break. further,
Since the attachment state of the ligature can be visually checked, the attachment can be performed easily, securely, and in a short time, so that the procedure time can be reduced.
