Two-armed surgical robot prototype targets pediatric brain tumors

Researchers say they’ve developed a surgical robot for removing brain tumors in children, and that it could also offer a less invasive, safer option for adult neurosurgery and other procedures.

The trick is using hollow, nitinol robot arms to allow neurosurgeons to swap tools during a tumor resection procedure, said Pierre DuPont. He’s the chief of pediatric cardiac bioengineering at Boston Children’s Hospital, and the corresponding author of a new research paper detailing the potential advantages of a two-armed neuroendoscopic robot.

In an interview with Medical Design & Outsourcing, DuPont traced the project back to conversations with Dr. Jim Drake, chief of neurosurgery at Sick…
