  • Publication number: 20210060418
    Abstract: Sliding movements between a button drive member and a manipulation button are reduced in a manipulation input device having a function of providing the haptic sense. Manipulation buttons (20R, 20L) individually have contact portions (20b) on sides opposite to sides to be pushed by a user, and are movable about rotation center lines (Ax1). Actuators (30R, 30L) and (230) have button drive members (31, 231) that contact the contact portions (20b) of the manipulation buttons (20L, 20R), and apply, to the manipulation buttons (20L, 20R), forces in opposite directions to directions in which the manipulation buttons (20L, 20R) are pushed. In addition, the actuators (30R, 30L, 230) have guides (34a, 234a) that define the directions in which the button drive members (31, 231) move, and the button drive members (31, 231) are slidable along the guides (34a, 234a).

  • Patent number: 10675047
    Abstract: A forceps system includes a forceps manipulator and a control unit. The forceps manipulator includes a forceps tip unit capable of bending with two degrees of freedom including a bending direction and a bending angle, a drive unit that generates a driving force for the forceps tip unit, an operation unit for instructing the bending direction and the bending angle, and a first detection unit that detects an angle in a rotation direction with respect to an axis of the drive transmitting unit. The control unit that controls the drive unit such that the forceps tip unit bends depending on a predetermined target bending direction and a predetermined target bending angle. The control unit sets a target bending direction on the basis of the bending direction instructed from the operation unit and the angle detected by the first detection unit.
