    摘要： A spring counterbalance mechanism balances a load with a spring. A cable has a protrusion fixed to the cable midway between two ends of the cable. The two free ends of the cable are fixedly coupled to one of the load or the spring, and a cable attachment is coupled to the remaining member. The cable passes through the cable attachment such that the protrusion is captive in the cable attachment and is movable between two stops in the cable attachment. The cable forms two segments each of which couples the spring to the load. The two segments of the cable pass over a pulley. A sensor coupled to the pulley senses rotation of the pulley allowing cable breakage to be detected by the anomalous rotation of the pulley.

    摘要： A slave manipulator manipulates a medical device in response to operator manipulation of an input device through joint control systems. The stiffness and strength of the slave manipulator are adjustable according to criteria such as the mode of operation of the slave manipulator, the functional type of the medical device currently being held by the slave manipulator, and the current phase of a medical procedure being performed using the slave manipulator by changing corresponding parameters of the control system. For safety purposes, such changes are not made until it is determined that it can be done in a smooth manner without causing jerking of the medical device. Further, an excessive force warning may be provided to surgery staff when excessive forces are being commanded on the slave manipulator for more than a specified period of time.

    摘要： A medical robotic system includes a surgical instrument, a robotic arm assembly, an input device, and a processor. The surgical instrument has an end effector and a sensor for sensing a force exerted by the end effector, and is operatively mounted on the robotic arm assembly. The processor is configured to receive commanded movement of the end effector from the input device, receive information of the force from the sensor, determine a reduced velocity of the commanded movement that would inhibit damage causing motion of the end effector, and control robotic manipulation of the surgical instrument in response to the commanded movement of the end effector while restricting the velocity of the commanded movement to the reduced velocity.
