The invention relates to a device for surgery used in microsurgery (eye surgery, glaucoma surgery, vitreo-retinal surgery, neurosurgery, plastic surgery, ENT, and / or other surgical fields), in laparoscopic surgery, endoscopic surgery, general surgery, gynecology, orthopedic and / or other human and/or animal surgical fields, more exactly to a device for cutting, suction, endo- illumination, endo-coagulation. This device can coagulate and/or remove by cutting and/or suction parts and/or tissues of the eye globe, but which can also be used for removing other parts and/or tissues of the body, with the possibility of visualizing through a fiber optic visioning system that can project images on a screen. The surgery device consists of two metal tubes of cylindrical shape, one outer tube (1) and one inner tube (2). that are arranged concentrically with respect to one another. The outer tube (I) being fixed while the inner tube (2) can be rotated around its longitudinal axis by means of mechanical, electromechanical and/or piezoelectric actuators, and/or by means of pneumatic (air or another) actuators. The actuators can be placed at the proximal part and/or at the base of the device and/or in a compartment separated from it at a short distance from the tip. The outer tube can be enveloped with fiber optic filaments that can be used for illumination, imaging and laser coagulation. The irrigation/inflation system consists of a cylindrically shaped hollow piece that slides onto the outer tube and on top of the finer optic envelope. The piece has an opening that is placed on the opposite side with respect to the cutting opening. Through this opening fluid (liquid or gas) is pumped in order to keep the pressure inside the virtual cavity (eye, peritoneum, and/or others) at a desired value. The flow of fluid is controlled by a system, not illustrated here, that is placed at some distance away from the end piece. This system maintains the desired pressure inside the virtual cav
