Minimally invasive surgery minimizes scarring and tissue damage. Harvard researchers have developed a groundbreaking micro-robot with a 5mm-diameter laser—as thin as a drinking straw—to enhance surgical precision.
Traditional surgery often relies on scalpels, leading to larger scars and greater muscle or tendon damage. Minimally invasive surgery addresses this by using tiny incisions, offering both aesthetic benefits and reduced trauma to surrounding tissues.
However, surgeons face challenges with precision during complex maneuvers. A January 13, 2021, study in Science Robotics introduces a 5mm-diameter laser-equipped micro-robot from Harvard's Wyss Institute, designed to overcome these limitations.
In minimally invasive procedures, surgeons use highly flexible instruments that extend hand precision for tissue cutting or hemostasis. Options include lasers, which operate in straight lines and are limited to line-of-sight areas, or energy cables/electrodes for broader access—but these risk collateral tissue damage due to reduced accuracy.
Wyss Institute robotics experts integrated laser guidance with flexible instrumentation in this micro-robot. Initial tests demonstrate its ability to navigate complex paths, perform precise ablations swiftly, and minimize risks to adjacent tissues.
This innovation supports surgeons in delicate procedures, building on the Institute's prior work like the mini-RCM robot for surgical assistance.
