Abstract: A method of determining hysteresis according to an example embodiment may include capturing a real-time image of the surgical robot driven according to a drive input, and measuring a drive angle of the surgical robot by comparing the real-time image to a previously rendered image data set of the surgical robot, and calculating a difference between the drive input and the measured drive angle.

Abstract: The present invention relates to an apparatus for preventing buckling of a flexible surgical instrument, and more particularly, to an apparatus for preventing buckling of a flexible surgical instrument for preventing the buckling when a catheter or an over-tube of a surgical instrument and the like is inserted into the human body. To this end, disclosed is a surgical-instrument feeder for preventing the buckling of flexible surgical instruments which comprises: a master driving unit for receiving a driving command from the user; and a feeder unit for feeding surgical instruments according to whether to interlock with the master driving unit or not interlock with the master driving unit, and feeding the surgical instruments supplied from the master driving unit so as to prevent the surgical instruments from buckling by means of the feeding control command.

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: Disclosed herein is an asymmetric rolling joint device of a surgical instrument which increases traction force by asymmetrically forming rolling contact surfaces of joint links facing each other. The asymmetric rolling joint device includes: a first joint link part which forms a joint of the surgical instrument; and a second joint link part coming into rolling contact with the first joint link part, wherein rolling contact surfaces where the first joint link part and the second joint link part come into rolling contact with each other are formed asymmetrically so as to increase traction force more than rolling contact surfaces which are formed symmetrically.

Abstract: A flexible drive manipulator according to an example embodiment may include a proximal portion, a plurality of joint portions drivably connected from an end of the proximal portion with respect to a longitudinal axis, a distal portion connected to an end of the plurality of joint portions, a pair of drive wires passing through the plurality of joint portions in parallel along the longitudinal axis, the pair of drive wires configured to drive the plurality of joint portions in a rotational direction of rotation with respect to a transverse axis perpendicular to the longitudinal axis, and a fixing wire passing through the plurality of joint portions in a shape of converging along the longitudinal axis, the fixing wire configured to adjust rigidity of the plurality of joint portions.
