A computer based, temperature controlled bipolar electrocoagulation system.
OBJECTIVE
To reduce complications during electrocoagulation particularly injury of other organs, a computer based, temperature controlled bipolar coagulation system has been developed. Under this system temperature in the tissue is kept between 60 degrees C and 95 degrees C during coagulation. A real time graphic display provides the surgeon with an actual temperature at the tip of the forceps during coagulation.


METHODS
Rabbit uterine horns were coagulated at 90 degrees C and were examined histologically and histochemically at 6 weeks after coagulation.


RESULTS
Electrocoagulation at 90 degrees C induced a total loss of LDH activity in the tissue. Lumen of the uterus was completely occluded when examined 6 weeks later.


CONCLUSIONS
This system with low temperature is sufficient for homogenous coagulation of the tissue.
