VR surgery

Richard Satava, a program manager for advanced medical technologies, has been a driving force bringing virtual reality to medicine, where computers create a “virtual” environment for surgeons.

“With virtual reality we’ll be able to put a surgeon in every trench(战壕),” said Satava. He     1     a time when soldiers who are wounded fighting overseas are put in mobile surgical units equipped with computers.

The computers would convey images of the soldiers to surgeons back in the U. S. The surgeons would look at the soldier through virtual reality helmets that contain a small screen     2     the image of the wound. The doctors would     3     robotic instruments in the battlefield mobile surgical unit that operate on the soldier.

Although Satava’s vision may be years away from standard     4     procedure, scientists are progressing toward virtual reality surgery. Engineers in California are developing a tele-operating device. As surgeons watch a 3D image of the surgery, they move instruments connected to a computer, which passes their movements to robotic instruments that perform the surgery. The computer provides     5     to the surgeon.

The technological     6     may not yet be part of the community hospital setting. However, with the passage of time, some of the machinery is     7     finding its way into civilian medicine. At Wayne State University Medical School, surgeon Lucia Zamorano takes images of the brain from computerized scans and uses a computer program to produce a 3D image. She can then move the 3D image on the computer screen to     8     the shortest and least invasive surgical path to the cancer. Zamorano is also using technology that     9     a needle to surgical instruments so that she can track their positions. While cutting away a cancer deep in the brain, she watches the movement of her surgical tools in a computer graphics image of the patient’s brain taken before surgery.

During these procedures surgeons are wearing 3D glasses for a better view. And they are commanding robot surgeons to cut away tissue more     10     than human surgeons can.

Satava says, “We are in the midst of a fundamental change in the field of medicine.”
