Definitions
- the present invention relates to an installation for treating diseased cells of living tissue in order to eliminate them.
- the present invention aims to remedy these drawbacks and proposes to create an installation for treating diseased cells from living tissue to eliminate them, of the type defined above, characterized in that it comprises A device analysis including
- C a computer managing the spectral information analysis device and the processing device for controlling the variation of the wavelength of the coherent light emitter, determining the or the useful wavelength corresponding to a maximum of the signal response received by the photoreceptor of the analysis device and controlling the light source by its adjustment circuit.
- the light source adjustment means regulates not only the precise wavelength of the light but also its power and its mode of emission, continuous or discontinuous, for example a pulse emission with pulses of duration short enough to be imperceptible. for the nervous system but with sufficient power to supply the destructive energy to the cells to be destroyed.
- the coherent light source is a laser.
- Figure 2 shows in its parts 2a and 2b, two diagrams of responses from the analysis of a sample of living tissue.
- the invention relates to an installation for treating diseased cells of living tissue to eliminate them.
- This installation consists of an analysis device 1, a photoemitter 2 and a photoreceptor 3 to illuminate a sample of living tissue 4 placed in a support 5.
- the photoreceptor 2 emits a coherent light but of length variable wave.
- the photoreceptor 3 receives the response signal R of the sample 4.
- sample 4 contains diseased cells, for example cancer cells
- the response R is different (FIG. 2b); this response presents a peak for certain wavelengths, for example ⁇ i.
- the installation includes a computer 6 which manages the assembly.
- This computer receives the response signal R from the photoreceptor 3 (this signal can optionally be processed and formatted in the analysis device 1).
- the computer 6 can then display a response curve on a control screen 7 or plot the curve on a plotter 8 or even provide information printed by the printer 9.
- the installation also includes a processing device 20 formed by an adjustment circuit 21 and a coherent light source 22 as well as an optical guide 23.
- the coherent light source 22 generates a coherent light of given wavelength ( ⁇ j).
- This wavelength ( ⁇ j) dependent on the wavelength ⁇ i supplied by the analysis device, imposed as a function of the processing to be carried out, is controlled by the computer 6 through the adjustment circuit 21.
- the circuit 21 adjusts the coherent light source 22 to precisely define not only the wavelength ( ⁇ j) but also the transmission power and the emission mode. This emission can be continuous or discontinuous, for example impulse.
- the control circuit 21 regulates the rate of work and the duration of transmission.
- the light guide 23 is a fiber guide opti ⁇ c. It comprises a tip 24 of a shape suitable for the treatment to be carried out depending on whether the surface to be treated is an external surface, a cavity or a surface released during a surgical intervention.
- the adjustment of the wavelength ⁇ j of the source 22 on the resonance frequency of the cells to be destroyed makes it possible to transmit to these cells the energy necessary for their destruction without touching the neighboring cells.
