Abstract: An imaging system for a surgical robot and a surgical robot. The imaging system includes: a fixed display device for acquiring and displaying image information about a surgical environment; a movable display device, which is coupled, so as to be movable relative, to the fixed display device, the movable display device configured to acquire and display the same image information as is displayed by the fixed display device; and a console having a support on which the fixed display device is mounted. The combined use of the movable display device with the fixed display device in the imaging system and the surgical robot provide more options of operation to an operator. The movable display device can be adjusted according to the desired comfort and personal preferences of the operator to provide the operator with an experience of increased operational comfort and reduce the fatigue of the operator.

Abstract: A surgical robot system includes a slave unit and a computing unit. The slave unit includes a robotic arm, a surgical instrument, a cannula and a sensing element. The robotic arm drives the surgical instrument to rotate about a remote center of motion (RCM). The cannula is detachably coupled to a terminal of the robotic arm and defines an axis passing through the RCM. The surgical instrument is detachably connected with the terminal of the robotic arm and extends distally through the cannula, and the sensing element is disposed on the cannula and senses an axial deformation of the cannula. The computing unit determines a radial force acting on the terminal of the surgical instrument, from a force on the cannula sensed by the sensing element, according to the principle of torque balance.

Abstract: The present invention provides a surgical robot system and a surgical instrument thereof, which can measure a contact force acting on a terminal end of the surgical instrument with enhance precision and accuracy. The surgical instrument includes a mechanical structure, a sleeve and a force sensor. The mechanical structure includes a shaft and an end effector connected to a terminal end of the shaft. The sleeve fixedly or detachably sleeves over the terminal end of the shaft. The force sensor includes a sensitive element and a peripheral measurement module connected thereto. The sensitive element is arranged on the sleeve and configured to acquire strain information of the sleeve.

Abstract: The application provides a surgical robot system, wherein the first tool arm and the first surgical instrument are configured to pull tissues and organs, the second tool arm and the second surgical instrument are configured to perform a surgical operation on tissues and organs, the control unit is configured to obtain a magnitude of a Cartesian force exerted by the tissues and organs on the first surgical instrument, and compare the magnitude of the Cartesian force exerted by the tissues and organs on the first surgical instrument with a preset force value; if the magnitude of the Cartesian force exerted by the tissues and organs on the first surgical instrument is less than the preset force value, the control unit controls the driving device to drive the first tool arm and the first surgical instrument according to the preset force value, to increase a traction force exerted by the first surgical instrument on the tissues and organs to the preset force value.
