A ligative suturer according to the present invention comprises a first rod which is connected with a ligative sutural member, and a second rod which is connected with the first rod to be bendable in the horizontal direction (L, R). A thread guard member which is capable of protrusion and storage is provided in the first rod, while a lever which can select the bending direction of the first rod in response to the situation of employment by an operator is provided in the second rod. Due to this ligative suturer, the operator can regularly bend the first rod toward him whether he handles the suturer with his left or right hand.
