Abstract
A surgical robotic system includes a robotic arm, an end effector movably connected thereto and provided with a movable end effector element driven by an actuator, and a force sensor arranged between the robotic arm and the end effector. The actuator is formed by a hydraulic cylinder. The robotic arm is provided with a hydraulic line connected to said hydraulic cylinder of the end effector.
Claims6
A surgical robotic system comprising:
- a robotic arm, an end effector movably connected to the robotic arm and provided with at least one movable end effector element driven by an actuator, and
- a force sensor arranged between the robotic arm and the end effector,
- wherein
- said actuator is formed by a hydraulic cylinder, and
