BACKGROUND The problem with all bipolar diathermy equipment is the adherence of the tissue to the prongs of the forceps. OBJECTIVE 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.

UI	MeSH Term	Description	Entries
D008838	Microcomputers	Small computers using LSI (large-scale integration) microprocessor chips as the CPU (central processing unit) and semiconductor memories for compact, inexpensive storage of program instructions and data. They are smaller and less expensive than minicomputers and are usually built into a dedicated system where they are optimized for a particular application. "Microprocessor" may refer to just the CPU or the entire microcomputer.	Computers, Personal,Microprocessors,Computer, Personal,Microcomputer,Microprocessor,Personal Computer,Personal Computers
D003880	Dermatology	A medical specialty concerned with the skin, its structure, functions, diseases, and treatment.
D004564	Electrocoagulation	Procedures using an electrically heated wire or scalpel to treat hemorrhage (e.g., bleeding ulcers) and to ablate tumors, mucosal lesions, and refractory arrhythmias. It is different from ELECTROSURGERY which is used more for cutting tissue than destroying and in which the patient is part of the electric circuit.
