PREFERRED EMBODIMENT OF THE INVENTION

[0039] In FIG. 1, and merely by way of example, an intramural myoma (1) is shown, formed between the inner wall of the uterus (2) and the dermal and epiploic/mesenteric layers (3) of the patient.

[0040] Well, according to the invention, the system of the invention is based on the simultaneous use of a series of devices, all of them managed by software and controlled from a user interface with its corresponding microprocessor and control unit (7) in which a screen (8) represents the location status of the optical fiber (4), both for the laser emission and for the angle of incidence in the degree of temperature transfer to the myometrial wall.

[0041] Consequently, among said devices there is a laser probe or optical fiber (4) associated with the corresponding hysteroscope (5), as well as an ultrasound machine (6) with 3D technology and active image management.

[0042] More specifically, the ultrasound machine (6) is placed on the skin layer (3) of the patient through a guidance system (9) duly monitored by the control unit (7), guidance system (9) in the that participate in slide-guides in two-dimensional X, Y, and angled axes, valid to establish the initial reference points or zero reading offset, defining a Cartesian guide to detect and correct the set-up lags that avoid anechoic interferences or others of intermediate lipid layer.

[0043] For its part, the probe or optical fiber (4), in addition to the function of transmitting element of the main beam of the evaporation laser, acts as a surface emitter for its location.

[0044] To do this, said optical fiber (4) has a main fiber beam (10) for transmitting the evaporation laser beam (FO) at a certain wavelength and at a certain power, modulated and controlled from the control unit (7), with the particularity that it includes a second beam (10) as an envelope, through which the bidirectional emission and reception, due to the rebound effect, of a pulsed laser from the source for the calculation of thermography, passes.

[0045] Consequently, in the main core of the optical fiber, the laser acts as a thermal scalpel to ablate the tumor by evaporation and removal of tissue by recirculation of the widening fluid of the uterine cavity by hysteroscopy (being the one that supports the greatest load of power), while the outer layer of shorter length and with a variable angle of attack, acts as a means of transferring the laser emission linked to the thermographic measurement of the external walls of the tumor.

[0046] According to FIG. 1, for the oriented control of the cutting probe or fiber optic (4), in its intrauterine location, the XYZ axes are defined in addition to the angular ZY and ZX, and for the rotation the axis with respect to the pelvic base, being on the axis Z in particular, the one that marks the depth of the introduced section of the workpiece with respect to the point 0 and the thermal reading the transfer. A technical detail is added to the probe in this section that acts as a reference for the positioning system and that validates the dynamic response of the proposed echolocation.

[0047] This determines six 6 positioning variables+application thermography.

[0048] From this structuring, and together with the initial set-up, the echo-guidance of the probe and the reception of reading of its positioning with respect to the uterine interspacing and the myoma tumor chamber is allowed, as a field of intervention, so that it is not necessary to specify previous trajectories on the first 3D tomographic image (initial reference).
