SMART scalpel gives surgeons superhuman precision

Ashley N. Rice, [email protected]

A new “smart” surgical tool uses a specialized optical fiber sensor to compensate for almost imperceptible hand tremors by making hundreds of precise position corrections per second – fast enough to keep a surgeon’s hand on target. Even the most skilled and steady surgeons experience tiny hand tremors when performing delicate tasks. Normally inconsequential, but for doctors specializing in fine-scale surgery such as operating inside the human eye or repairing microscopic nerve fibers, freehand tremors can pose a serious risk for patients. Researchers from...Read full article

    optical coherence tomography
    Optical coherence tomography (OCT) is a non-invasive imaging technique used in medical and scientific fields to capture high-resolution, cross-sectional images of biological tissues. It provides detailed, real-time, and three-dimensional visualization of tissue structures at the micrometer scale. OCT is particularly valuable in ophthalmology, cardiology, dermatology, and various other medical specialties. Here are the key features and components of optical coherence tomography: Principle of...
    optical fiber
    Optical fiber is a thin, flexible, transparent strand or filament made of glass or plastic used for transmitting light signals over long distances with minimal loss of signal quality. It serves as a medium for conveying information in the form of light pulses, typically in the realm of telecommunications, networking, and data transmission. The core of an optical fiber is the central region through which light travels. It is surrounded by a cladding layer that has a lower refractive index than...
