Cooperative minimally invasive telesurgical system
Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.
1. A medical robotic system comprising:
a plurality of robotic arms;
a first control station having first and second input devices;
a second control station having a third input device; and
a controller configured to switch associations between the plurality of robotic arms and the input devices of the first and second control stations in response to selection inputs received from an operator of the first control station, during the performance of a medical procedure on a patient, to operatively couple the operator selected robotic arms to the operator selected input devices.
2. The medical robotic system of claim 1 , further comprising an arm selector coupled to the controller for selecting between a plurality of modes, wherein a first arm is operatively associated with the second control station when the controller is in a first mode, and wherein the first arm is operatively associated with the first control station when the controller is in a second mode, the operatively associated arm moving an associated tool in response to movement of the operatively associated input device.
3. The medical robotic system of claim 1 , wherein a second arm is operatively associated with the first control station when the controller is in the first mode, and wherein the second arm is operatively associated with the second control station when the controller is in the second mode.
4. The medical robotic system of claim 1 , further comprising:
an association interrupting input device;
wherein the controller is configured to interrupt control of one of the plurality of robotic arms by a currently associated one of the input devices of the first and second control stations upon operator activation of the association interrupting input device, accept an operator selection of another one of the plurality robotic arms to be associated with the currently associated one of the input devices of the first and second control stations while disassociating the another one of the plurality of robotic arms from a previously associated one of the input devices of the first and second control stations, and associate the currently associated one of the input devices of the first and second control stations to the plurality of robotic arms so that a tool associated with the another one of the plurality of robotic arms is manipulatable according to manipulation of the previously associated one of the input devices of the first and second control stations following user deactivation of the association interrupting input device.
