Viewing system for use in a surgical environment
The invention relates to a viewing system for use in a surgical environment. Various real object detection devices detect locations of real objects in a real environment, such as a patient and body part of patient, medical staff, robots, a cutting tool on a robot, implant transferred by robot into body part, surgical tools, and disposable items. A map generator generates a map that forms a digital representation or a digital twin of the real environment. Various guiding modules including a room setup module, an anatomy registration module, a surgical planning module, and a surgical execution module make use of the digital representation to guide virtual or real objects based on the digital representation.
