Robotic Surgery Opens Up

If the open-source approach to building robot surgeons can cut costs and improve performance, patients will increasingly find them at the other end of the scalpel

For much of its brief history, robot-assisted surgery has been synonymous with Intuitive Surgical, Inc.’s da Vinci system. It’s the only robot with U.S. Food and Drug Administration (FDA) approval to help surgeons perform a number of laparoscopic soft-tissue procedures, including hysterectomies, gall bladder and kidney removals, prostate cancer treatment and heart valve operations. Da Vinci has improved vastly since Intuitive introduced it more than a decade ago. Like many new technologies, however, it has experienced growing pains, leading some engineers and medical professionals to question whether a single company can meet growing demand while still delivering a safe product.
 
A team of researchers is looking to address these issues by developing a robotic surgery system based on hardware designs and software that are freely available. In this open-source approach, the builders would keep whatever intellectual property they’ve invested in the project but must make their knowledge and discoveries available to others.
 
The researchers, from the University of California, Santa Cruz, and the University of Washington (U.W.), hope their efforts will lead to a number of advances in surgical-robot technology that would stem from a basic design that wouldn’t change from device to device. The idea is that the costs of building—and buying—multimillion-dollar robotic surgery systems would decrease, as would the learning curve to use them.
