A surgical robotic system comprises a surgeon console, remote surgical robot, and a control unit. The surgeon console comprises a base connected to a hand controller by a linkage, the linkage comprising a plurality of joints whereby the configuration of the linkage can be altered. The surgeon console comprises a driver to drive each joint to move. The surgeon console further comprises a presence sensor to sense the presence of a surgeon's hand on the hand controller. The control unit receives user inputs from the hand controller, converts the received user inputs into command signals for driving manipulation of the surgical robot, receives sensory inputs from sensors including the presence sensor, and responds to, during a surgical operation, concurrently detecting from the received sensory inputs (i) the lack of a surgeon's hand on the hand controller, and (ii) an external force additional to gravity acting on the hand controller, by controlling the drivers to drive the joints with a damped response in the direction of the external force.

TORQUE LIMITING RATCHETING HANDLE FOR MEDICAL INSTRUMENT

A torque limiting ratcheting handle for a medical instrument is provided that includes a ratchet shifter, a tool connector, a torque coupler, and a rear power housing. The handle provides clockwise and counterclockwise ratcheting and limits the amount of torque in one direction while allowing for maximal torque in the opposite direction. In one aspect, the ratcheting handle may include a drive shaft removeably connected to a power tool or, alternatively, to a handle grip for manual manipulation.

TORQUE LIMITING HANDLE FOR MEDICAL INSTRUMENT

A torque limiting handle for a medical instrument is provided that includes a tool connector, a torque coupler, and a rear power housing. The handle limits the amount of torque in one direction while allowing for maximal torque in the opposite direction. In one aspect, the torque limiting handle may include a drive shaft removeably connected to a power tool or, alternatively, to a handle grip for manual manipulation.
