Star Trek: Scalpel-Free Surgery vs. Today: Ultrasound Surgery



In the film Star Trek IV: The Voyage Home, Dr. McCoy is horrified by barbaric 20th-century surgical methods, in particular the venerable science of trephination: "My god, man! Drilling holes in his head's not the answer!" To heal a seriously injured Commander Pavel Chekov without cutting him open, McCoy uses the futuristic gizmo pictured here. Bloodless surgery may sound like science fiction, but doctors today are using high-intensity ultrasound beams in lieu of the knife to treat some health problems, including injured lungs, uterine fibroids, and tumors. If the trend continues, operating rooms of the future will have more bloodless surgical tools and fewer shiny scalpels.
