The invention relates to an electro-mechanical-type handpiece, specially designed to be used with a laser generator, particularly those that use CO 2 laser and provide a laser beam in fractional mode, and according to a pattern of homogeneous points aligned in rows, columns or diagonally, the configuration of which allows the internal tissue along the entire length of the vagina to be treated and, as a consequence of this treatment, the pelvic floor to be retracted, such that the urinary bladder is consequently elevated and, owing to the change in angle thereof, slight or moderate losses of urine are resolved or improved. In addition, the device can be used to treat the inner surface of the vagina, reducing vaginal laxity caused by childbirth and age.
