A biological tissue is sutured or ligatured, a suture and ligature member such as a ligature wire is cut, and then a holding member is reliably recovered from the body. In a holding member of a medical ligature tool, a protrusion is disposed between distal lateral holes, and proximal lateral holes, so that it protrudes outward in a diameter direction thereof. On the other hand, a concave portion is formed in the inner periphery of a cutting member. When the cutting member is extended to cut a ligature wire, the concave portion is fitted to the protrusion to allow the holding member to engage the cutting member.
