Robotic arm system, method and computer program
A robotic arm system for surgery is described. The method includes: processing circuitry configured to: apply a virtual barrier preventing a human controlled surgical device from entering an area within a surgical scene; and release the virtual barrier in response to a gesture.
1. A robotic arm system for surgery, comprising:
processing circuitry configured to
apply a virtual barrier that prevents a human controlled surgical device from entering an area within a surgical scene and to restrict movement of a robotic arm holding a surgical device, and
on condition that the surgical device held by the robotic arm corresponds to a surgical device to perform a next surgical procedure, release the virtual barrier in response to a gesture, wherein the gesture is selected based on a starting position of the human controlled surgical device of the next surgical procedure.
2. A system according to claim 1 , wherein the surgical procedure is one of cautery, ligature, extraction or puncture.
3. A system according to claim 2 , wherein the gesture is related to a particular structure located in a surgical site protected by the virtual barrier.
4. A system according to claim 2 , wherein an area of the surgical site defined by the virtual barrier is dependent upon the type of the human controlled surgical device.
5. A system according to claim 2 , wherein the virtual barrier defines an area around an organ within the surgical scene.
6. A system according to claim 2 , wherein the gesture is determined based on the urgency with which the area should be accessed.
7. A system according to claim 6 , wherein the urgency is determined by the condition of the patient.
8. A system according to claim 2 , further comprising a user interface configured to receive an input from the user and the gesture is performed on the user interface.
9. A system according to claim 2 , further comprising a sensor configured to recognize the surgical site and wherein the processing circuitry is configured to define a plurality of areas within the surgical scene based on the recognized surgical site.
10. A system according to claim 9 , wherein the sensor is one of an image sensor, a time of flight sensor or a multispectral sensor.
11. A method of operating a robotic arm system for surgery, the method including:
applying a virtual barrier preventing a human controlled surgical device from entering an area within a surgical scene and restricting movement of a robotic arm holding a surgical device; and
on condition that the surgical device held by the robotic arm corresponds to a surgical device to perform a next surgical procedure, releasing the virtual barrier in response to a gesture, wherein the gesture is selected based on a starting position of the human controlled surgical device of the next surgical procedure.
