During the videolaparoscopic surgery is necessary the permanent exposure of an appropriate visual field to the surgeon and his assistants work with the maximum security possible. The importance of an efficient pneumoperitoneum to a secure practice of a videolaparoscopic surgery is indisputable. The advance of modern technology provided the developmentof very efficient electronic insuflators, however too expensive. The objective of this work is to show an alternative model of insuflator much cheaper and more efficient. This model can provide a competent pneumoperitoneum with a permanent control of the ideal intracavitary pressure and an appropriate restitution in case of eventual down pressures. We have already realised about a hundred videolaparoscopics surgical procedures in human corpses (adults and fetus) and in research animais like dogs end pigs. The system is perfectly adapted to experimental videolaparoscopic surgery. Its efficiency was proved. It can also be expanded to some surgical procedures in vivo and in little-sized laboratory animais like mouses and rabbits.
