Abstract
The present invention relates to a method, such as a surgical method for assisting a surgeon for placing screws in the spine using a robot attached to a passive structure. The present invention also related to a method, such as a surgical method for assisting a surgeon for removing volumes in the body of a patient using a robot attached to a passive structure and to a device to carry out said methods. The present invention further concerns a device suitable to carry out the methods according to the present invention.
Claims20
A method of using a robotic surgical system to assist a surgeon in removing a target volume in a body of a patient during surgery, the method comprising:
- storing, by a processor of the robotic surgical system, a location of the target volume to be removed, wherein a stay-in zone is defined based at least in part on the target volume;
- after a surgical instrument affixed to the end of an end effector of the robotic surgical system enters the target volume, controlling, by the processor, a position of the robot such that the surgical instrument remains in the stay-in zone;
- providing, based on a position of the tool in the target volume, a repulsive/wall-like force to the surgeon manipulating the surgical instrument to inform the surgeon of the position of the surgical instrument inside the stay-in zone.
