摘要： A surgical instrument includes a base body detachable from a surgical robot arm, a support body connected to the base body, and first and second jaws. The first jaw is rotatably supported on a first shaft supported by the support body and includes a first opening pulley, a first closing pulley, and a first blade part. The second jaw is rotatably supported on the first shaft and includes a second opening pulley, a second closing pulley, and a second blade part. The first opening pulley is axially separated from the first closing pulley and the second opening pulley is axially separated from the second closing pulley. An axial direction of the first shaft is orthogonal to an opening and closing direction of the first blade part and the second blade part.

摘要： High-frequency forceps for medical use that include a manipulation part including a grasping portion that is conductive; a cylindrical part that is inflexible, through which a wire for manipulation of the grasping portion and a cable for supplying current to the grasping portion are guided; and an insulating part that electrically insulates the manipulation part from the cylindrical part. The cylindrical part includes: an outer layer made of an insulating material; an inner layer made of an insulating material; and an intermediate layer located between the outer layer and the inner layer, and having a lower insulation resistance and a higher stiffness than the outer layer and the inner layer.

摘要： A surgical instrument holding device includes first and second parallel links, a wiring member and a connector. The first parallel link has two first link portions arranged in parallel with each other, each having one end in an axial direction as a first end portion. The second parallel link has two second link portions arranged in parallel with each other, each having one end in an axial direction as a second end portion. The wiring member is disposed along the parallel links. The connector has two first link supporters by which the respective first end portions are rotatably supported, two second link supporters by which the respective second end portions are rotatably supported, a first wiring supporter that supports the wiring member on a part between the two first link supporters, and a second wiring supporter that supports the wiring member on a part between the two second link supporters.

摘要： A surgery-assisting device includes a robot arm that includes plural movable bodies that are operably connected in order in a connecting direction, a surgical instrument connected to a distal end of the robot arm, and one or more actuators that generate a driving force that operates one or more of the movable bodies. The movable bodies include one or more distal-side movable bodies that is provided distally in the connection direction, and one or more proximal-side movable bodies that is provided proximally in the connection direction. An operation tolerance of the one or more distal-side movable bodies is higher than an operation tolerance of the one or more proximal-side movable bodies.

摘要： A surgical device includes a forceps device, driven portions to which a driving force is transmitted from outside the surgical device, plural wires, each being fixed to one of the driven portions and transmitting respective movements of the driven portions to the forceps device. The forceps device includes grasping portions that may be opened and closed by a movement of a first wire of the plural wires, and a joint portion that may be bent by a movement of one or more second wires of the plural wires.

摘要： An object is to provide a camera head adaptor that allows an endoscope to be detachably attached with a simple operation and that can prevent stress on electrical wirings, optical cables, etc. in an insertion portion due to a camera head being held. The camera head adaptor for holding an endoscope having a camera head comprises: a holding portion that holds the camera head of the endoscope in a detachable manner; a connecting portion that extends along an observation optical axis of the camera head and can be attached to a support structure; and a coupling portion that couples the holding portion and the connecting portion.

摘要： A medical robot system including a memory and a central processing unit that performs operations including receiving measurement signals of forces measured at two or more points on one or both of a surgical tool and a slave device that supports the surgical tool, generating image information for displaying information of the forces as images in association with the two or more points at which the forces are measured, based on the measurement signals, and outputting the image information that is generated to a display device that displays the image information in a second display region of the display device which is different from a first display region of the display device in which information on operation of the surgical tool is displayed.
