    Area of Science:

    • Ophthalmology
    • Surgical Instrumentation
    • Electrosurgery

    Background:

    • Standard De Wecker's iris scissors are widely used in ophthalmic surgery.
    • Certain eye conditions present a high risk of bleeding or metastasis, complicating surgical procedures.
    • A need exists for surgical tools that offer enhanced hemostasis and reduced metastasis risk.

    Purpose of the Study:

    • To describe a novel modification of standard De Wecker's iris scissors.
    • To evaluate the efficacy of the modified scissors, incorporating a cauterizing effect.
    • To determine the optimal electric current range for the cauterizing function.

    Main Methods:

    • Standard De Wecker's iris scissors were modified through electrical insulation.
    • The modified scissors were tested for their cutting and cauterizing capabilities.

    Related Experiment Videos

  • The optimal electric current range (20-40 mA) for the cauterizing effect was identified.

    • Main Results:

    • The modified scissors successfully combined cutting and cauterizing functions.
    • The cauterizing effect was found to be advantageous in managing bleeding.
    • An optimal electric current range of 20-40 mA was established for effective cauterization.

    Conclusions:

    • The insulated, cauterizing De Wecker's iris scissors offer a valuable adjunct in ophthalmic surgery.
    • This modified instrument is particularly beneficial for eye conditions with high bleeding or metastasis risk.
    • The device utilizes an effective electric current range of 20-40 mA for optimal performance.
