Dynamic scaling for a robotic surgical system
A robotic surgical system in which the system applies a scaling factor between user input from a user input device and corresponding movements of the robotic manipulator. Scaling factors may be applied or adjusted based on detected conditions such as the type of instrument being manipulated, detected distance between multiple instruments being manipulated, user biometric parameters.
1. A robot-assisted surgical system comprising:
a robotic manipulator configured for robotic positioning of a surgical instrument in a body cavity,
at least one user input device moveable by a user,
at least one processor and at least one memory, the at least one memory storing instructions executable by said at least one processor to:
receive user input in response to movement of the input device by a user,
receive instrument type input in response to positioning of a surgical instrument on or in proximity to the manipulator,
receive input from a user specifying a surgical procedure type,
apply a scaling factor based on the instrument type input and the specified surgical procedure type,
cause the manipulator to move the first surgical instrument in response to the user input, based on the scaling factor.
2. The system of claim 1 , wherein, the instructions are further executable by the at least one processor to:
predict a subsequent task to be performed based on the specified procedure type;
receive instrument type input based on signals from the sensor in response to positioning of a second surgical instrument on, or in proximity to the robotic manipulator, and applying a scaling factor based on the instrument type input, the predicted subsequent task, and the specified procedure type.
3. The system of claim 1 , wherein:
the instructions are further executable by the at least one processor to receive input identifying a user; and the scaling factor is applied based on the instrument type input and the user identity.
4. The system of claim 1 , wherein the manipulator includes at least one RFID reader, and wherein the instructions are executable by said at least one processor to receive the instrument type input based on input from the RFID reader in response to positioning of a surgical instrument on or in proximity to the RFID reader, the surgical instrument having an RFID tag.
5. The system of claim 1 , wherein the system includes an optical sensor, and wherein the instructions are executable by said at least one processor to receive the instrument type input based on input from the optical sensor.
6. A robot-assisted surgical system comprising:
a robotic manipulator configured for robotic positioning of a surgical instrument in a body cavity,
at least one user input device moveable by a user,
at least one processor and at least one memory, the at least one memory storing instructions executable by said at least one processor to:
receive user input in response to movement of the input device by a user,
receive instrument type input in response to positioning of a surgical instrument on or in proximity to the manipulator,
receive input identifying a user,
apply a scaling factor based on the instrument type input and the identified user,
cause the manipulator to move the first surgical instrument in response to the user input, based on the scaling factor.
7. The system of claim 6 , wherein the system includes at least one biometric sensor, and wherein the instructions are executable by said at least one processor to receive input identifying a user based on input from the at least one biometric sensor.
8. The system of claim 7 , wherein the at least one biometric sensor is at least one of an image sensor configured for facial recognition, an eye scanner, a fingerprint scanner, or a voice sensor.
9. The sensor of claim 6 , wherein the system includes an auxiliary input device comprising at least one of a graphical user interface, touch screen, keyboard or mouse, and wherein the instructions are executable by said at least one processor to receive input identifying a user based on input from said auxiliary input device.
10. The system of claim 6 , wherein the system includes a user identification sensor configured to scan a user identification device, wherein the instructions are executable by said at least one processor to receive input identifying a user based on input from said user identification device.
11. The system of claim 6 , wherein the user identification device comprises at least one of an identification wristband or badge.
