Robotic surgical systems with roll, pitch, and yaw realignment including trim and flip algorithms
A robotic surgical system or simulator includes an input device, a display device, and a processing unit. The display device includes a representation of a surgical tool that is operably associated with the input device. The processing unit is in communication with the input device and is associated with the representation of a surgical tool to rotate the representation about a first axis of movement based on a scaled rotation of the input device about a first axis of rotation. In an aligned configuration, the input device is aligned with the representation about the first axis of rotation. When the input device is misaligned with the representation, the processing unit varies the scaled rotation of the input device to return the input device to the first aligned configuration until the input device is misaligned about the first axis of rotation a first predetermined offset from the aligned configuration.
1. A method of operating a surgical robot or surgical simulator, the method comprising:
receiving, with a processing unit, a rotation of an input device of a robotic surgical system about a first axis of rotation; and
scaling the rotation of the input device to a rotation of a representation of a tool on a display device about a first axis of movement, the processing unit down scaling rotation of the input device when the input device is moved away from an aligned configuration to realign the input device with the representation of a tool until the input device is within a predetermined offset with the representation of a tool about the first axis of rotation.
2. The method according to claim 1 , wherein scaling rotation of the input device to the rotation of the representation of a tool on the display device about the first axis of movement includes the processing unit up scaling rotation of the input device when the input device is moved towards the aligned configuration to realign the input device with the representation of a tool until the input device is within the predetermined offset with the representation of a tool about the first axis of rotation.
3. The method according to claim 1 , further comprising selecting the predetermined offset.
4. The method according to claim 3 , wherein selecting the predetermined offset includes the processing unit determining the predetermined offset based on the representation of a tool.
5. The method according to claim 1 , further comprising flipping the aligned configuration of the input device 180° about the first axis of rotation when the input device is misaligned with the representation of the tool greater than a predetermined misalignment.
