In a surgical robot, a robot controller controls an articulated robot so that an arm base rotationally moves in an arc shape around a predetermined position set at a position away from the arm base.

Surgical robot and operation method for articulated robot

A controller of a surgical system is configured to: set a center point; set a reference point on a reference line that is an extension of a rotation axis of a proximal end roll joint or that is offset from the extension in a direction normal to the extension; and position joints of a manipulator arm such that a shaft passes through the center point and that a reference plane passes through the reference point, the reference plane including a rotation axis of a distal end roll joint that coincides with a central axis of the shaft and crossing a rotation axis of a pivotal joint.

Surgical system and method of controlling surgical manipulator arm

A surgical robot includes a controller configured or programmed to control a display to superimpose guide information indicating a moving direction of a medical cart based on a steering angle of a steering device on an image captured by an imaging device and display the guide information.

Surgical robot and control method of surgical robot

A surgical robot includes: a surgical instrument; a manipulator that supports a surgical instrument without holding a trocar and includes an instrument interface to which the surgical instrument is attached, an arm including rotational joints, and a prismatic joint; and a controller. The controller may store a center of motion of the surgical instrument and control motion of the manipulator such that with the shaft inserted through the trocar and the tool located in a body cavity of the patient, a relationship T≥L is established in a case of L≤T, wherein: L represents an intra-body cavity length of the surgical instrument; Trepresents a maximum possible linear movement amount of the prismatic joint from an origin position along the axial direction; and Trepresents a first linear movement amount of the prismatic joint from the origin position to a current position along the axial direction.

Surgical assist robot and method of controlling the same

A surgical robot includes robot arms, an arm base, and a control device. Each of the robot arms includes a base portion, a tip portion that can hold a medical instrument, and links. The link adjacent to the base portion is connected to the base portion through a rotational joint. The control device controls the robot arm having at least seven degrees of freedom among the robot arms such that when viewed from a direction parallel to an axial direction of a rotation axis of the rotational joint, a first portion of a first link is located between a second portion of the base portion and a third portion of the tip portion.
