Description
215~003 THERAPEUTIC LASER DEVICE
FIELD OF THE INVENTION
The present invention relates to therapeutic lasers.
s BACKGROUND OF THE INVENTION
Therapeutic lasers are useful in the treatment of certain types of soft tissue injuries. Typically, the lasers used have been low powered devices that produce laser light in the frequency of between 600 nm and 905 nm. The laser therapy generallyrequires the injured tissue to be exposed directly to the laser light for fixed intervals of time, depending on the nature of the injury. Exposure to laser light not only lessens the pain associated with certain injuries, but actually speeds the healing of the treated tissues. The frequency and intensity of the laser light and the exposure time are 15 important factors when selecting a treatment regiment for an injury. Certain wavelengths of laser light are more effective in treating different types of injuries. In particular, 905 nm laser light has been found useful in treating arthritis.
The intensity of the laser light used to treat an injury is a key factor in its effectiveness. Preferably, the more intense the laser light, the better. Unfortunately, if 20 the laser light is too intense, adverse side effects can result. Typically, higher intensities tend to cause heating of the affected area of tissue, which in turn can limit the usefulness of the treatment regiment. Also, the total exposure time can be an important factor. If 21~003 an injury is not exposed to laser light for an appropriate interval of time, insufficient healing may result. Furthermore, the laser apparatus traditionally needed to produce higher intensities tended to be large and bulky.
To properly treat an injury using laser therapy, all of the injured tissue must be 5 exposed to laser light. Laser light generators tend to produce narrow beams of laser light; therefore, a regiment of repeated exposures is often required to complete a treatment. The treatment regiment typically takes a long time since the laser light must be exposed to all of the affected tissue. Existing therapeutic laser devices are insufficient since the therapist must hold the probe above the treatment area for the duration of the 10 exposure time. Also, since each patient will require a unique treatment regiment, the therapist must reset the laser therapy device for each patient, thereby consuming more of the therapists time. There is a need for a therapeutic laser device that is effective and easy to use.
SUMMARY OF THE INVENTION
The present invention is directed at a therapeutic laser device comprising a laser emitter for producing laser light at a preselected wavelength, a portable control device operatively coupled to the laser emitterfor controlling the output of laser light, the portable control device being sufficiently portable to be strapped to a patient's body, and a flexible 20 connection means for movably connecting the laser emitter to the control wand, the flexible connection means being able to position and hold the laser emitter at an angle from the portable control device.
21S~003 The present invention is also directed at a therapeutic laser device comprising a laser emitter for producing laser light at a preselected range of wavelengths, a portable control device operatively coupled to the laser emitter for controlling the output of the laser light, the laser emitter and portable control device being able to selectively produce pulses of laser light at a frequency of between 0 to 30,000 pulses per minute, each pulse having an intensity of between 8000 and 10,000 watts per cm2.

A215~oo3 DETAILED DESCRIPTION OF THE INVENTION
Referring firstly to figure 1, the present invention is a therapeutic laser shown generally as item 10 comprising a control box 12, a connector cable 16 and a laser probe 14. Laser probe 14 is a portable control mechanism having a body 15 and a removable probe tip 22. Control box 12 has a computer screen 18 and input buttons 20. Input buttons 20 are used to program control box 12. Connector cable 16 is an electrical cable having a plurality of internal wires (not shown) for powering laser probe 14.
Referring now to figures 2 and 3, laser probe 14 has a body 24, end 42 and side walls 25 and 27. Laser probe 14 is provided with connector elements, shown as item 30 in figure 2 and item 34 in figure 3, for connecting one laser probe to another. Preferably, connector element 30 takes the form of a groove while connector element 34 takes the form of a tongue. Connector elements 30 and 34 form a dove tailed 'tongue in groove' connection when tongue 34 is slid into groove 30. Preferably, groove 30 is formed in side wall 25 and tongue 34 is formed on opposite side wall 27. Laser probe 14 is alsoprovided with clamp 32 for securing the laser probe to a patient by means of a belt (item 70 in figure 6). Control switches 26 and 28 are provided for turning the probe on or off.
Laser probe 14 acts as a portable control mechanism for turning the laser on or off.
Laser probe tip 22 is attached to end 42 of the laser probe. Probe tip 22 comprises a laser diode retaining section 36, a neck 38 and a connector element 40.
Connector element 40 is adapted to releasably connect probe tip 22 to end 42 of laser probe 14. Diode retaining section 36 contains the laser diode. Neck 38 movably connects the laser emitter (diode) to body 15 of the laser probe. Neck 38 is a flexible , connector and can be bent to orient diode retaining section 36 at an angle from body 24 of laser probe 14.
Referring now to figure 4, body 24 of laser probe 14 is hollow and houses a circuit board 46. Circuit board 46 contains some of the electronic circuitry necessary to operate the laser diode contained in diode retaining section 36. Circuit board 46 is operatively coupled to connector cable 16 and switches 26 and 28. Circuit board 46 is also operatively coupled with connector cable 16 via wires 44. End 42 of body 24 is provided with a recessed opening 56 adapted to receive connector element 40 of probe tip 22.
Female electrical connector element 50 is contained within recess 56 and is operatively coupled to circuit board 46 via electrical cable 48. Connector element 40 is provided with male electrical connector element 58. Male electrical connector element 58 is provided with electrical contacts 56 adapted to make electrical contact with electrodes 52 of female electrical connector element 50. Male electrical connector element 58 is operatively coupled to laser diode 64 via electrical cable 60. Laser diode 64 is retained in diode retaining section 36 via restraint 62. Diode retaining section 36 is provided with lens 66 that protects laser diode 64.
Referring now to figure 6, laser probe tip 22 can be bent such that diode retaining section 36 is at an angle from body 24 of laser probe 14. The bendable laser probe tip 22 facilitates the use of laser probe 14. Laser probe 14 may be attached to a patient's body 72 by means of belt 70; the straps being secured to the laser probe by clamp 32.
Probe tip 22 can then be bent into the proper orientation to shine laser light on the particular portion of the patient's body to be treated. The operator need not hold the laser 215~003 probe during the treatment, therefore freeing the operator to perForm other tasks.
Furthermore, since laser probe 14 is secured to the patient, it is less likely that the laser light emitted by the probe will strike areas of the patient's body that are not intended for treatment.
Laser probe 14 can be connected with other identical laser probes via connector elements 30 and 34. As seen in figure 7, several laser probes 14 can be connected such that a bank of laser probes, shown as item 68, are formed. The entire bank of laser probes 68 can then be strapped to a patient's body via a belt 70. Laser tips 22 of each laser probe 14 can then be bent and positioned such that a particular area of the patient's body will be exposed to the combined laser light. This increases the treatment surface area and thereby decreases the treatment time for the procedure.
Neck portion 38 of laser probe tip 22 is articulated to enable it to bend.
Alternatively, neck portion 38 can be made of a single section of flexible tube. The neck portion is preferably bendable in an infinite number of directions and angles.
Alternatively, the neck portion could take the form of a joint that bends in only one direction. An alternate embodiment of the tip portion of the invention is illustrated in figure 5. The alternate laser probe tip 100, is provided with a connector element 112, diode retaining portion 110 and joint 114. End 116 of connector element 112 is configured to be retained within recess 56 of end 42 of laser probe body 24 (see figure 4). Diode retaining portion 110 also houses a laser diode (not shown) that is operatively coupled to a female electrical connector element contained in connector element 112.
Joint 114 permits diode retaining portion 110 to be pivoted relative to connector element 112. When probe tip 100 is attached to body 14 of the laser probe, joint 114 permits the variable positioning of diode retaining portion 110 relative to the rest of the laser probe.
Control unit 12 comprises a housing 11 having a liquid crystal computer display 18 mounted there on. A circuit board, not shown, is contained within housing 11 and is operatively coupled to computer display 18, cable 16 and programming buttons 20.Programming buttons 20 enable a physician to program the device. Control unit 12 can select the pulse rate of laser light emitted by laser probe 14 from a range of between 0 to 30,000 pulses per second. Control unit 12 can also select the duration of each pulse in micro-seconds and the intensity of each pulse in watts/cm2. The pulse duration can be selected from a range of between 1 second and a few lus. The pulse intensity can be selected from a rang of between 8,000 to 10,000 watts per cm2. By selecting the pulse rate, the pulse intensity and the duration time per pulse, control unit 12 can selectively control the peak power rate and the average power rate for the laser light emitted by laser probe 18. It has been discovered that a laser beam having a very high peak intensity and a relatively low average intensity can be achieved by appropriately selecting the pulse rate, pulse intensity and pulse duration. A beam having a high peak intensity and a relatively low average intensity can penetrate deeper into the patient's tissue without the harmful side effects resulting from highly intense beams.
Control unit 12 is provided with a central processor unit such that the control unit can be programmed to make laser probe 14 emit a selected regiment of laser light having a preselected peak intensity, average intensity and duration. Control unit 12 is further provided with sufficient computer memory to store a series of regiments for different 2I5~003 patients. Control unit 12 can be programmed with each patient's name and treatment regiment, eliminating the need to re-program the device after each treatment. Buttons 20 are used by the operator to select the treatment regiment for each patient.
Laser probe tip 22 can be replaced with another laser probe tip having a different 5 laser diode. Hence, laser probe 14 can be adapted to produce laser light of a different frequency by simply replacing laser probe tip 22. The replaceable laser probe tip 22 and programable control unit 12 permits the whole unit to treat a variety of aliments for a variety of patients.
To use the device for a particular patient, the appropriate laser probe tip 22 is first 10 inserted. Laser probe 14 is then strapped to the patient's body and probe tip 22is adjusted to shine the laser light at the specific area to be treated. Then the operator uses buttons 20 to display the patient's name on computer display 18. The treatment regiment is displayed adjacent the patient's name on computer display 18. If the treatment regiment is acceptable, the operator again uses buttons 20 to select the treatment and 15 then turns on probe 14. The treatment then proceeds. Since probe 14 is secured to the patient's body, the operator is free to perform other tasks. Once the treatment is completed, laser probe 14 may be unstrapped from the patient's body.
While the invention has been illustrated and described with respect to the preferred embodiment, it will be appreciated by those skilled in the art that numerous variations of 20 these embodiments may be made without departing from the scope of the invention.
