Definitions
- the present invention relates to medical technology, and is an improvement and development of Japanese Patent Application No. 612/166 (Physical medical device using one holographic technology. Invention by the present inventors). It is about. Background art
- Holography can realize a three-dimensional real image.
- a computer-generated hologram created from this image using a computer is called computer holography.
- This computer holography can freely create images of virtual objects. Therefore, by using computer holography and transmitting electromagnetic waves, a real image of focus can be freely formed inside the human body.
- Holography One primary use of physical medical devices is in hyperthermia for cancer. Cancer cells are immature cells and die at temperatures above 43 ° C. Ordinary cells, on the other hand, are old cells and are more resistant to heat than young cells. Hyperthermia for cancer is a method that uses this temperature difference to kill cancer cells. By focusing on cancer cells using holography, it is possible to heat only cancer cells with little heating of surrounding cells. This is a holographic physical medical device. This is a female When using it, the affected part can be cut off from the living body at a local high temperature, crushed, and then sucked out with a syringe to enable surgery without cutting the human body surface.
- the problem to be solved by the present invention is that the method of the electronic variable hologram used for the physical medical device shown in the above-mentioned conventional Japanese Patent Application No. 612/166 is abstract. On the other hand, more concrete and practical forms are required.
- Means for solving the above problem of the present invention is a phase of a semiconductor laser array (a number of semiconductor laser elements arranged in rows and columns and electronically controlled as a whole).
- a controlled device Using a controlled device, a hologram-shaped pattern consisting of the light and dark of the laser oscillation and stop of the semiconductor laser element is identified as a hologram, and the laser oscillation of the semiconductor laser element is identified as a reproduction light (reference light).
- a semiconductor laser array variable oscillation hologram which is one type of electronic variable oscillation hologram, is used.
- the variable oscillation hologram of the semiconductor laser array is described in Japanese Patent Application No. Hei 10-2010 Patent Application No. 747778 (invention by the present inventor).
- laser-array hologram Semiconductor laser array variable oscillation hologram
- a holographic single laser focus image is formed on the cancer cell nodule inside the human body whose location is specified by the diagnostic device, and the cancer cell nodule is heated.
- holography 'laser can image multiple focal points at the same time, so cancer can be treated efficiently.
- FIG. 1 is a sectional view showing the principle of holography.
- FIG. 2 is a cross-sectional view showing the principle of diffraction by slits.
- FIG. 3 is a cross-sectional view showing a portion of a variable oscillation hologram of a semiconductor laser array.
- FIG. 4 is a cross-sectional view of a laser array-hologram physical medical device.
- Illumination wave reference wave
- Example 1 Laser 'array.
- Method of hyperthermia for hologram cancer and its device Lasers, arrays, and holograms, that is, an array of semiconductor laser elements 12 arranged in a matrix and controlled by a control circuit 13, and interference fringes formed by the transmission and stop of the phase-controlled laser beams 11 emitted by each element 12
- a method of a holographic physical medical device characterized by using a device whose pattern is identified as a hologram 1 as a holographic laser / generator, and the device. This holography-laser is used for hyperthermia of cancer.
- this hologram (dry plate) 1 is irradiated with reference light (reproduction light)
- a spherical wave 4 is generated from each point 3 of the transparent portion, and the combined wave forms the next wave front.
- the composite wave becomes a wave from both points and two waves 5 and 6. Therefore, is wave 6 from reference light source A a force that is natural? A wave 5 from the object point B also occurs.
- the virtual image B, of the object point B is reproduced.
- the reproduced image of the object point B includes a virtual image B ′ and a real image.
- a virtual image B is reproduced at the place where the original object point B was, and a real image is reproduced at a position which is angularly shifted by twice the incident angle of the reference light.
- computer holography calculates the hologram of an arbitrary virtual object by a computer to create an interference fringe pattern, and irradiates the hologram as a hologram with a reproduction light to generate a three-dimensional image of the virtual object.
- Real images can be realized. That is, the equivalent of the hologram of the virtual object shown above can be realized by the interference fringe pattern formed by the blinking of each laser element 12 in which a large number of laser elements 12 of the semiconductor laser array are arranged in a matrix.
- the laser oscillation of each laser element 12 is “dot” and the laser stop is “dark”, the dot corresponds to the transparent part 3 of a normal hologram, and the flash corresponds to the opaque part.
- the combination of the interference fringes has the function of a hologram, and at the same time, is a device for generating reproduction light.
- the laser oscillated by the laser elements 1 and 2 becomes a spherical wave 11 that spreads radially (combined at a position that is more radial and more advanced in practice).
- the combined wave forms the next wavefront, and the whole becomes holographic.
- a real real image of holography and laser from a wide angle S is formed on a cancer cell nodule 19 inside the human body whose position is specified by a separate diagnostic device.
- Cancer cells are immature cells and are vulnerable to heat and die at about 43 ° C. In contrast, normal cells, which are old cells, do not die at 43 ° C.
- Hyperthermia for cancer uses this temperature difference to treat cancer. Since the irradiation is performed from the wide angle S, the degree of heating rapidly decreases at the position far from the focal point, so that the device has few side effects in principle.
- a plurality of focal points can be imaged simultaneously by the holographic laser, so that cancer can be treated efficiently.
- Example 2 A scalpel method using a laser 'array' hologram and its device.
- Lasers, arrays, and holograms that is, semiconductor lasers 1 2 arranged in rows and columns, controlled by a control circuit 13, and interference fringe patterns formed by transmitting and stopping the phase-controlled lasers 11 emitted from each element 1 2
- a method for a holographic-physical medical device characterized in that the device identified as a hologram 1 is used as a holography / laser generator, and the device is used. Holography by using it ⁇ Laser is used for scalpel.
- a holographic single laser focus image is formed on the diseased part 20 inside the human body whose position is specified by the diagnostic device, and the diseased part is locally heated at a high temperature. If 20 is separated from the living body, crushed, and then sucked out with a syringe, surgery can be performed without cutting the human body surface. If the crushed diseased part 20 is small, spontaneous outflow is also possible.
- a practical laser / array / hologram physical / medical device can be manufactured.
- this device is used for hyperthermia for cancer, a large number of holographic laser-focused real images are simultaneously formed on the cancer cell nodule 19 inside the human body located by the diagnostic device, and the cancer cell nodule is formed. Heating 19 can efficiently treat cancer.
- surgery can be performed without cutting the human body surface. Since the holographic laser 15 in these devices emits light from a wide angle S, the device has in principle few side effects.
