Craniotomy is a challenge for both doctors and patients. Researchers at the university of Utah in the United States have devised a "robot doctor" that can open craniotomy, which is 50 times faster than a real doctor. William Kurdish neurosurgeon at the university of Utah, in an article published in the journal of neurosurgery focus, said today, the doctor was in a surgical operation as archaeology, "we try to slowly remove the skull, in order to avoid bruising sensitive parts of the brain". Sometimes the process takes two hours. Using a new robot doctor, even the most complex craniotomy takes only two or three minutes to complete. The patient needs to undergo a CT scan to determine the location of the nerve and major blood vessels. Doctors then set the best "route" for the scans, as simple and accurate as using an electronic map. 

He said kurds, robot doctors quickly, clean, safe, and can reduce the time in the brain is exposed to the air, shorten the patient's anesthesia time, reduce the risk of infection, avoid human errors and cut down the cost of operation. However, the robots are not yet in clinical use
