Now, robots do surgeries without doctors Washington: A physician-guided robot carrying out surgeries on patients is not new, but scientists have developed a next generation robot that could eliminate a surprising element from that scenario, the doctor. Feasibility studies conducted by Duke University bioengineers have demonstrated that a robot -- without any human assistance -- can locate a man-made, or phantom, lesion in simulated human organs. It can also guide a device to the lesion and take multiple samples during a single session, according to the researchers who believe as the technology is further developed autonomous robots could soon perform many more simple surgical tasks. "Earlier this year we demonstrated that a robot directed by artificial intelligence can on its own locate simulated calcifications and cysts in simulated breast tissue with high repeatability and accuracy," said Kaicheng Liang, a Duke scientists and a member of the research team.
