Robotic-assisted device for positioning a surgical instrument relative to the body of a patient

摘要

The robotic device for positioning a surgical instrument relative to the body of a patient includes a first robotic arm with a device for rigidly connecting to at least one surgical instrument, a device for anatomical realignment of the first arm by realigning an image that is of an area of the anatomy of the patient, and a device for compensating the movements of the first arm on the basis of detected movements. One version of the device includes at least one second robotic arm having sensors for detecting inner movements of the anatomical area, and a device for controlling the positioning of the first arm relative to sensed inner movements and to the outer movements induced in the second arm.

主权项

1. An automated robotic surgical assistance device for positioning a surgical instrument relative to an anatomical area of a body of a patient, comprising:
a first robotic arm and a receiver disposed at an end of the first robotic arm, the receiver adapted to stably receive at least one surgical instrument, so as to hold and guide the surgical instrument; a second robotic arm and a sensor disposed at one end, the sensor adapted and configured to be in contact with the anatomical area, the sensor adapted to detect movement in the anatomical area; and a controller in operative communication with the first robotic arm, the controller adapted to, in response to movement in the anatomical area detected by the sensor, automatically control the position of the first robotic arm, wherein the first robotic arm has a first position, based on an image of the anatomical area acquired previously, to position the surgical instrument along a planned trajectory, the controller further adapted to automatically control the position of the first robotic arm to compensate for movement of the anatomical area relative to the surgical instrument to maintain the position of the surgical instrument along the planned trajectory.
