Optics for endoscopic surgery, 5mm in diameter, around which two compartments between 2.1 and 2.3mm thick and between 170º and 180 ° in circumference are arranged, which will globally occupy almost the entire circumference of the optics in the entire length of it. These two compartments will preferably be covered with stainless steel, determining an upper and a lower compartment with a single point of connection to each other at the end of the optical end. Through these compartments a sterile saline serum flow will be established at a temperature between 40 ° C and 50 ° C, avoiding the fogging of the optics tip by water vapor. The upper compartment will have at least 3 holes for the exit of the serum and washing of the tip of the optic. The 3 holes will be covered by a stainless steel plate, movable by a lever to cover and uncover the holes in the upper compartment. Between the lower compartment and the optics there is a superabsorbent sponge, attached to a spring with a resting angle of between 90 ° and 100 °, and this in turn attached to a stainless steel plate, movable by means of a lever to extract and hide the sponge Once the sponge is removed, it takes the resting position angulation, thanks to the spring, and contacts the surface of the optic tip, cleaning and drying it.Óptica para cirugía endoscópica, de 5mm de diámetro, alrededor de la cual se disponen dos compartimentos de entre 2,1 y 2,3mm de grosor y entre 170º y 180° de circunferencia, que globalmente ocuparán la práctica totalidad de la circunferencia de la óptica en toda la longitud de la misma. Estos dos compartimentos irán recubiertos preferentemente de acero inoxidable, determinando un compartimento superior y uno inferior con un único punto de conexión entre sí a la altura del extremo final de la óptica. Por estos compartimentos se establecerá un flujo de suero salino estéril a temperatura entre 40°C y 50°C, evitando evitar el empañamiento de la punta de la óptica por vapor de agua.#El compartimen
