Abstract: The present invention relates to an apparatus for locking a surgical instrument by using magnetic force and, more specifically, to an apparatus for locking a surgical instrument by using magnetic force, which installs or uninstalls an instrument for microsurgery by using magnetic force in order to reduce a load that may occur during installing/uninstalling an instrument for microsurgery.

Abstract: Provided is a stiffness-reinforced surgical system. A stiffness-reinforced surgical system includes a plurality of links provided rotatably with each other to form a joint device, a main tendon configured to form a traction force for driving the links, an auxiliary tendon configured to form a traction force to resist rotation of the links, and a controller configured to control the traction forces of the main tendon and the auxiliary tendon. According to example embodiment, it is possible to provide a stiffness-reinforced surgical system configured such that an overtube forms sufficient flexibility while being inserted into the lumen and forms high stiffness during lesion removal, and a control method thereof.

Abstract: A slave device according to an example embodiment may comprise: a lower shaft; an upper shaft connected to the lower shaft so as to be able to slide with a single degree of freedom; a lower gripper rotatably supporting the lower shaft; an upper gripper rotatably supporting the upper shaft; a lower delta robot movably supporting the lower gripper; and an upper delta robot movably supporting the upper gripper.

Abstract: A surgical robot includes a surgical tool including a bendable joint portion, and a bending tendon connected to the joint portion and configured to bend the joint portion, a tube connected to the surgical tool and configured to accommodate the bending tendon therein, a base housing configured to rotatably support the tube and accommodate the bending tendon that passes through the tube, a bending driver configured to grasp the bending tendon, and translate in a longitudinal direction parallel to a rotation axis of the tube with respect to the base housing, and a rotation driver configured to rotatably support the tube with respect to the base housing, wherein when the tube rotates, the rotation driver is connected to one portion of the bending driver that grasps the bending tendon, and rotates the tube and the bending tendon together.
