    Area of Science:

    • Ophthalmology
    • Surgical Technology
    • Medical Devices

    Background:

    • Precise diathermy application is crucial in ophthalmic surgery, especially within narrow incisions and delicate structures.
    • Undesirable parafocal tissue damage and uveal bleeding are significant challenges in scleral flap dissection and retinal tear treatment.

    Purpose of the Study:

    • To introduce a novel thin, conical diathermy electrode designed for enhanced precision in confined ophthalmic surgical areas.
    • To evaluate the electrode's efficacy in preventing uveal bleeding and treating posterior retinal breaks.

    Main Methods:

    • Design and fabrication of a thin, conical diathermy electrode with a smooth-surfaced, bent, insulated tip.
    • Application of the electrode in simulated and/or actual surgical scenarios involving narrow incisions and scleral flaps.

    Related Experiment Videos

  • Assessment of the electrode's ability to deliver focal diathermy and its impact on parafocal tissue and bleeding.

    • Main Results:

    • The electrode facilitates precise, focal diathermy delivery within narrow incisions, corners, and angles of dissected scleral flaps.
    • The design effectively minimizes undesirable parafocal tissue damage.
    • The electrode proved valuable in preventing uveal bleeding from sclerochoroidal incisions and treating small posterior retinal breaks.

    Conclusions:

    • The developed diathermy electrode offers a precise and safe tool for ophthalmic surgeons operating in confined spaces.
    • Its specific design addresses critical challenges such as uveal bleeding and the treatment of small retinal breaks, improving surgical safety and efficacy.
