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 23 of a medical ligature tool 2, a protrusion 35 is disposed between distal lateral holes 33a, 33b and proximal lateral holes 34a, 34b so that it protrudes outward in a diameter direction thereof. On the other hand, a concave portion 30 is formed in the inner periphery of a cutting member 10. When the cutting member 10 is extended to cut a ligature wire 20, the concave portion 30 is fitted to the protrusion 35 to allow the holding member 23 to engage the cutting member 10.
