Methods, systems, and devices for controlling movement of a robotic surgical system
Various exemplary methods, systems, and devices for controlling movement of a robotic surgical system are provided. In general, a plurality of surgical instruments are simultaneously usable during performance of a surgical procedure. One or more of the plurality of instruments is coupled to a robotic surgical system, that is configured to control movement of the one or more of the plurality of instruments.
1. A surgical system, comprising:
a first electromechanical arm configured to have a first surgical instrument removably coupled thereto, the first arm being configured to move so as to adjust a position of the first surgical instrument removably coupled thereto relative to a first surgical target;
a second electromechanical arm configured to have a second surgical instrument removably coupled thereto, the second arm being configured to move so as to adjust a position of the second surgical instrument removably coupled thereto relative to a second surgical target;
a first sensor attached to the first arm, the first sensor being configured to detect an impending collision between the first and second arms by determining when the second arm is within a threshold minimum distance of the first arm; and
a controller configured to be in electronic communication with the first sensor, the controller being configured to trigger performance of a remedial action in response to the detected impending collision.
2. The system of claim 1 , wherein the first sensor is configured to detect the impending collision using energy emitted by the first sensor.
3. The system of claim 2 , wherein the emitted energy includes at least one of light, electricity, and sound.
4. The system of claim 2 , wherein a maximum range of the emitted energy defines the threshold minimum distance.
5. The system of claim 1 , wherein the first sensor includes a mechanical extension extending from the first arm, the mechanical extension being configured to detect the impending collision by coming into contact with the second arm.
6. The system of claim 5 , wherein a size of the mechanical extension defines the threshold minimum distance.
7. The system of claim 1 , wherein triggering performance of the remedial action includes providing a notification to a user of the detection of the impending collision, the notification including at least one of an audible sound, a visual display on a display device, a haptic signal, and a light.
8. The system of claim 7 , wherein the controller triggers the notification to be provided before the detected impending collision occurs.
9. The system of claim 7 , wherein the controller triggers the notification to be provided after the detected impending collision occurs.
10. The system of claim 1 , wherein triggering performance of the remedial action includes stopping movement of the first arm.
11. The system of claim 1 , wherein triggering performance of the remedial action includes altering a previously-instructed movement path of the first arm to another movement path of the first arm determined by the controller as avoiding the impending collision.
12. The system of claim 1 , wherein triggering performance of the remedial action includes changing a configuration of the first arm or a configuration of the second arm.
13. The system of claim 1 , wherein triggering performance of the remedial action includes moving the second arm to avoid the impending collision.
14. The system of claim 1 , wherein the second arm has a second sensor coupled thereto, the second sensor being configured to detect an impending collision between the first and second arms by determining when the first arm is within a threshold minimum distance of the second arm, the controller being configured to be in electronic communication with the second sensor, and the controller being configured to trigger performance of a remedial action in response to the impending collision detected by the second sensor.
15. The system of claim 1 , further comprising a user input device configured to receive an input from a user indicating a desired movement of the first instrument removably coupled to the first arm, wherein the controller is configured to be in electronic communication with the user input device and the first arm, and the controller is configured to control movement of the first arm based on the input received by the user input device.
16. A surgical method, comprising:
moving a first electromechanical arm of a robotic surgical system that includes one or more additional electromechanical arms, each of the arms having a surgical instrument coupled thereto;
sensing an impending collision between the moving first arm and one of the one or more additional electromechanical arms using a sensor attached to the first arm; and
in response to sensing the impending collision, performing a remedial action that addresses the sensed impending collision prior to occurrence of the sensed impending collision.
17. The method of claim 16 , wherein performing the remedial action includes providing a notification to a user of the sensed impending collision, the notification including at least one of an audible sound, a visual display on a display device, a haptic signal, and a light.
18. The method of claim 16 , wherein performing the remedial action includes stopping the movement of the first arm.
19. The method of claim 16 , wherein the movement of the first arm is along a predetermined path defined by a user, and performing the remedial action includes changing the predetermined path to avoid the impending collision.
20. The method of claim 16 , wherein performing the remedial action includes changing a shape of the first arm or a shape of the one of the one or more additional electromechanical arms.
