And Now, Robodoc!
A robot in California performs its first invasive surgery on a human patient.
Medical robots in the U.S. have been used to locate hard-to-find tumors and guide a surgeon’s scalpel, but have never actually performed surgery on people. Now that line has been crossed. At Sutter General Hospital in Sacramento, California, a 90-kg machine called Robodoc has operated on its first human patient: a 64-year-old man with a bad hip.
The robot played a key role in a total hip replacement, one of 500,000 such operations performed each year. The trick in these procedures is to create a snug hole into which the artificial hip snaps. The standard method is to jam a cutting tool into the thighbone with a handheld mallet. Robodoc, using the high-speed drill at the end of its mechanical arm, can ream a cavity that is 20 times as precise.
Robosurgery doesn’t have to stop at the hip. In Europe, where officials are less squeamish about such things, robots have assisted in operations on the brain, the prostate and the inner ear.
