    Area of Science:

    • Vascular Surgery
    • Microsurgery
    • Surgical Technology

    Background:

    • Precise hemostasis is crucial in microvascular and hand surgery to prevent adjacent tissue damage.
    • Bipolar coagulation is a precise technique where current is theoretically confined to tissue between forceps tips.

    Purpose of the Study:

    • To confirm the efficacy and safety of bipolar coagulation for controlling small vessel branches in microsurgery.
    • To evaluate the impact of bipolar generator characteristics on surgical outcomes.

    Main Methods:

    • Experiments were conducted on rats to assess bipolar coagulation.
    • A bipolar generator producing continuous-sine-wave current with impedance sensing and automatic shutdown was utilized.

    Main Results:

    Related Experiment Videos

    • Bipolar coagulation effectively controlled vessel branches without disturbing parent vessels.
    • No adverse effects were observed on adjacent anastomoses.
    • The generator's features prevented sparking, charring, and tissue adherence.

    Conclusions:

    • Bipolar coagulation is a safe and effective method for precise hemostasis in microvascular surgery.
    • Generator characteristics, such as continuous-sine-wave current and impedance sensing, are vital for optimal performance and safety.
