Abstract
BACKGROUND: The problem with all bipolar diathermy equipment is the adherence of the tissue to the prongs of the forceps. OBJECTIVE AND METHODS: We describe a new computerized bipolar coagulator (Coa-Comp/M) with electronic feedback of the tissue impedance that automatically starts and shuts off coagulation thus preventing overheating, undue tissue damage and sticking of the forceps. The fully automation implies that no footswitch or handcontrol is necessary. The coagulator was tested during 2 years in advanced dermatologic surgery. RESULTS: A log memory recorded the number of coagulations according to effect and coagulation time. A power setting of 16W was appropriate for effective coagulation of most vessels; 99% of the coagulations were faster than 1.3 seconds necessitating automatic control for preventing sticking and charring. CONCLUSIONS: The automatic bipolar coagulator saves time and avoids sticking of the forceps. It is a useful tool in dermatologic surgery demanding repeated coagulations for hemostasis.
