Description
- The present application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application No. 61/295,051 filed Jan. 14, 2010, entitled Scanning Mechanism and Treatment Method for LLLT or Another Light Source Therapy Device, the disclosure of which is hereby incorporated herein by reference in its entirety.
- 1. Field of the Disclosure
- The present disclosure relates generally to low-level laser therapy and, more specifically, to a mechanical scanning device for use in low-level laser therapy applications.
- 2. Description of the Related Art
- The use of light for treating people and animals is well known. Since the early history of mankind people have used the light from the sun to help cure ailments. In the mid-twentieth century attempts were made to use concentrated light for treating wounded soldiers in World War II.
- More recently, the use of laser light in therapy has been shown to reduce pain, induce anti-inflammatory activity, induce healing processes and induce skin rejuvenation. The laser, which is based on the quantum phenomenon of stimulated emission, provides an excellent source of concentrated light for treating patients. The laser allows the use of a selected intensity, monochromatic, and essentially coherent light. This has been found to be effective in treating people for various ailments.
- Low-level laser therapy (“LLLT”) is the application of visible red or near-infrared light emitted from a low power laser for therapeutic purposes. At present, there are several variations of LLLT devices, such as devices having one light source which covers a small area of the body, shower devices which contain a two or more light sources and therefore cover a larger body area, and cluster devices which combine a variety of light sources, having different wave lengths and energy distributions. On many occasions, in order to cover a larger area, the beams generated by the light source have divergent angles and do not remain coherent.
- Many treatments with LLLT devices or other light sources require the treatment of a wide or large area of the human body rather than a small area or specific spot. Typically, a therapist scans the treatment area by moving the LLLT device or other light source device or probe by hand. The results of scanning in such a way are limited as the treatment does not always cover the desired area properly with the required light and/or energy dose to each treatment area unit.
- The present disclosure provides an apparatus and method for treating an area with a low-level laser or another light source or energy source such as an ultrasonic energy source, for example, device so the distribution of the light or other energy on the treatment area can be custom designed for a particular treatment procedure and repeated in the same manner for all similar treatments.
- In one embodiment according to the present disclosure, an apparatus includes a light source and a scanning mechanism attached to the light source and adapted to impart a desired motion to the light source. The scanning mechanism may be an electric motor rotating the light beam or beams generated by the light source to provide a desired energy distribution pattern on a treatment area or to cover a wide treatment area, applying different light sources and different wavelengths, each with a different energy distribution on each of a plurality of selected treatment areas. The light source may include a laser, such as a laser diode, for example. In another embodiment, the light source may include two or more light sources, each light source generating a light beam having a different wavelength, thus providing a composite coherent light beam.
- In another embodiment according to the present disclosure, a method of treatment includes generating a light beam and scanning the light beam across a treatment area in a predetermined pattern for providing a desired energy distribution pattern at a treatment area. Scanning the light beam may include rotating a light source which generates the light beam or, alternatively, moving the light source in two dimensions to scan the light beam or beams across a wide treatment area. In another embodiment the light source may be a cluster of light sources wherein the scanning the light source provides sequential irradiation of a plurality of unit areas of a treatment area with each of the two or more light beams providing an energy distribution corresponding to each of the two or more light beams to each of the plurality of unit areas
- In another embodiment of the present disclosure, an apparatus including a support plate is provided having a plurality of mounting points formed therein. The support plate may be a semi-rigid belt or web having a plurality of light source modules mounted at selected ones of the mounting points to form a predetermined energy distribution pattern at the surface of a treatment area. The apparatus includes a controller and power supply coupled to the support plate for providing control signals and power to the array of light source modules.

- Referring to
FIG. 1 , a scanning mechanism 100 to create a circular energy distribution on a treated area according to the present disclosure is shown. Aflexible arm 101 is attached to abase 109 at one end thereof. Ascanning mechanism 103, such as an electric motor, for example, is attached at the opposite end of theflexible arm 101 and is supported by thearm 101. In some embodiments, theflexible arm 101 comprises a flexible tube wherein electrical wiring and power cables (not shown) may be routed. Asource 105 is attached to thescanning mechanism 103.Scanning mechanism 103 is adapted to impart motion to thelight source 105 in a desired manner. For example, in one embodiment,scanning mechanism 103 rotates thelight source 105 about the axis of thelight beam 107 thereby rotating thelight beam 107 about its axis.Light source 105 may be a low-level laser or other suitable light source which generateslight beam 107 to illuminate a desiredarea 111 to be treated.Scanning mechanism 103 rotates or otherwise moves thelight source 105 such that thetreatment area 111 is scanned by thelight beam 107 to provide a desired energy distribution over the treatment area. As used herein, the term “light source” is used to designate the source of an energy beam or beams which provide energy to the treatment area during an LLLT procedure. While light energy is used as an example in the present disclosure, the term “light source” may refer to any suitable energy source such as an ultrasonic energy source, for example. Also, the term “scanning” or “scanned” as used herein includes all motions, such as spinning, rotating, vibrating, sliding, oscillating, and the like. - In one embodiment,
light source 105 comprises a low-level laser that provides as output an elongated monochromaticcoherent laser beam 107 that is collimated by a lens (not shown) directly from a laser diode embedded inlight source 105. The effects of LLLT appear to be limited to a specified set of wavelengths of laser emissions. The typical wavelength is in the range 600-1000 nm (red to near infrared), although research shows that some wavelengths outside this range may also be useful. The typical laser average power used in LLLT treatment is in the range of 1-500 mW. While some high-peak-power lasers in the range of 1-100 W may be used, a short pulse width limits the power at the treatment area. The typical average beam irradiance then is 10 mW/cm2-5 W/cm2. The standard laser diode beam typically has a divergence of about 5-7 degrees along its width and about 30 to 40 degrees along its length. Typically, a lens is utilized to correct the beam to a narrow beam. In an exemplary embodiment of the disclosure, the resultingelongated beam 107 is essentially coherent having a light beam with an essentially common phase as accepted for laser diode emission for use in LLLT. In some embodiments, thelight source 105 provides amonochromatic laser beam 107 that may be an invisible infrared beam. In some embodiments, the wavelength oflaser beam 107 may be 800 to 900 nanometers (nm). Alternatively, U.S. patent application Ser. No. 12/534,878 filed Aug. 4, 2009, entitled Handheld Low-Level Laser Therapy Apparatus, which is incorporated by reference in its entirety herein, describes using a lens (not shown) to form a collimated elongated beam to cover a larger area, for example an area of 3-6 cm by 0.5 to 1 cm. - In some embodiments wherein the
monochromatic laser beam 107 is an invisible infrared beam, a visible light source, for example, an LED, (not shown) may be incorporated with thelight source 105 to provide a supplementary visible light beam to accompany theinvisible laser beam 107. In some embodiments, the visible light beam may coincide with the invisible laser beam, or the visible light beam may illuminate an area that surrounds thelaser beam 107. - In some embodiments,
light source 105 may be a group or cluster of two or more light sources such as lasers, for example. Each such light source is separate and independent of the other light sources in the cluster. Each light source generates a separate beam of light at a different wavelength and may provide a beam of more or less power than each of the other light sources in the cluster. Thescanning mechanism 103 may be an electric motor which slowly rotates the light source cluster, such as at 2 revolutions per minute, thus irradiating each particular unit area of the treatment area with an energy beam having a different wavelength and power to provide a desired energy distribution at any given time. Each particular unit area of the treatment area is then irradiated with each of the generated energy beams in turn over a given time period as a function of the cluster rotation rate. - Referring to
FIG. 2 , a graph illustrating a linear energy distribution of an LLLT or other light source device, and the linear energy distribution while the device is being used with a rotating mechanism according to the present disclosure is shown.Curve 201 illustrates the energy distribution over a treated area of the light beam along the long dimension of thelight beam 107, when it is not rotating. When thelight beam 107 is rotating, using themotor 103,curve 203 illustrates the energy distribution created on the treatedarea 111 by the rotatinglight beam 107. Rotation of thelight beam 107 produces a more uniform energy distribution acrosstreatment area 111. - Referring now to
FIG. 3 , a scanning mechanism incorporating two light sources generating light beams having different wavelengths according to the present disclosure is shown. Alight source module 303 is attached to amotor 301.Motor 301 is adapted to impart motion to thelight source module 303 in a regular, desired manner to scan a desiredtreatment area 315. For example, themotor 301 may rotate thelight source module 303 about the axis of a light beam 311 to illuminatetreatment area 315 with an energy distribution similar to that illustrated bycurve 203. Two or morelight sources light source module 303.Light sources laser beam light source module 303 may incorporate onelaser 305 that emits a beam having a wavelength of 635 nm, and asecond laser 307 that emits a beam having a wavelength of 808 nm. Bothsuch lasers laser beams output coupler 309, such as a dichroic beam-splitter, dichroic prism or half-silvered mirror, for example.Output coupler 309 combines the twolaser beams lasers lasers - Referring now to
