  • Title: Computerized bipolar diathermy with scissors and forceps in cutaneous surgery.
    Author: Stenquist BC, Holt PJ, Motley RJ.
    Journal: Dermatol Surg; 2002 Jul; 28(7):601-2. PubMed ID: 12135515.
    Abstract:
    BACKGROUND: Bipolar diathermy coagulates tissue as effectively as monopolar with less lateral tissue injury and no risk of interference with cardiac pacemakers or joint prostheses. OBJECTIVE: To test a novel computerized bipolar diathermy machine for combined cutting and coagulation in dermatologic surgery. METHODS: A divided cable was used to deliver current from a computerized bipolar diathermy unit to both scissors and forceps. The bipolar diathermy unit senses tissue contact with the instruments and starts automatically; a built-in microcomputer measures tissue impedance and automatically terminates the current when tissue coagulation is achieved. RESULTS: The equipment has been used successfully in more than 200 patients undergoing dermatologic surgery. The advantages were a reduced operating time and a more secure hemostasis. The microprocessor controlled bipolar diathermy unit minimized any tissue adherence to the instruments during use. CONCLUSION: We recommend the use of insulated scissors and computerized bipolar diathermy for safe and efficacious coagulation and cutting in dermatologic surgery.
