The present invention relates generally to a portable chiropractic adjustor for use in chiropractic adjustment of musculoskeletal structures. More, particularly, this invention concerns an improved power operated chiropractic-adjusting device for use in spinal manipulative therapy to apply impact forces or thrusts to a human body.
The chiropractic art is generally concerned with adjusting misaligned body structures by manually manipulating the various joints in the human body. Of more specific interest in the art, however, is the spinal column which is comprised of several interconnected musculoskeletal structures or vertebrae. Unlike other, less critical body structures, the spinal column must be treated or manipulated with extreme caution because of its link with the central nervous system.
The human spine is susceptible to many different pathologic abnormalities including misalignment, miscellaneous trauma and pain, and degeneration as a result of age or disease. By employing various physical therapy techniques, though, a chiropractor, or one skilled in the chiropractic art, may be able to successfully treat a pathologic spine. Successful treatment will not only relieve any pain or discomfort that the patient might be suffering, but will also improve the overall quality of life of that patient.
One common spinal-adjustment technique involves applying thrusts or forces to the afflicted region of the spine. In particular, this technique involves either “mobilizing” the spine (i.e. passively moving the spine with relatively slow cyclic or oscillatory motion), or “manipulating” the spine (i.e. applying an impulsive thrust or force in a well-defined direction to a specific region of the spine). Depending on professional affiliations, this technique is referred to as chiropractic adjustment, osteopathic manipulation, orthopedic manual therapy, and/or spinal manipulative therapy.
There are several well-known procedures or techniques for “manipulating” or administering impulsive thrusts to a spine. One technique involves applying one or more rapid thumb thrusts to misaligned or afflicted vertebrae. Thumb thrusts, however, tend to be both imprecise in magnitude and location and tiresome to administer. Another technique involves using a manually operated chiropractic-adjusting instrument. For instance, U.S. Pat. No. 4,116,235, issued to Fuhr et al. (“Fuhr”); Fuhr U.S. Pat. No. 6,702,836; Fuhr U.S. Pat. No. 6,379,375; Keller et al. U.S. Pat. No. 5,626,615; Keller et al. U.S. Pat. No. 5,656,017; and U.S. Pat. No. 4,498,464, issued to Morgan, Jr., disclose such instruments.
Throughout the years it has also been known that power driven devices at times can offer benefits or advantages in use over the manually operated devices.
Electric solenoid operated adjustors such as ones described in Evans U.S. Pat. No. 4,841,955 issued in 1989 or Adelman U.S. Pat. No. 4,682,490, issued in 1987, can provide adjusting and controllability benefits over manual devices. However, using an electrical appliance close to the body can be potentially hazardous and even prohibited by governmental regulatory agency rules or regulations and power supply cords can get in the way.
Thus, numerous efforts have been made to develop a power operated thrusters with all of the desired features and benefits required for safe and varied usage of such devices. Examples of such an approach in pneumatic operated thrusters is shown in U.S. Pat. No. 4,716,890, issued in 1988 to Bichel and references cited in the Bichel patent.
While the Bichel thruster as described did seek to overcome disadvantages presented in prior art devices, it still did not provide certain features and advantages required to achieve wide spread acceptance and use by chiropractic practitioners.
By way of example, it may be noted that such prior devices including Bichel are capable of only delivering a single thrust or stroke, provide only manual adjustability of stroke lengths; provide force adjustment by changing stroke length and change air pressure only at the compressor or supply source. In addition they involve complicated multiple parts designs which make them more costly to manufacture and more difficult and costly to maintain or use. Recently, a pneumatic thruster of Frye U.S. Pat. No. 6,503,211 has solved some of the problems and objections of the field.
The primary object of the present invention is to provide an improved power operated chiropractic instrument that is “tunable” or settable as to load, amplitude, and frequency within a user selected range of natural frequency.
A more specific object of the present invention is to provide a portable device with annunciators or indicators of settings such as preload and readiness to operate.
An even more specific object is to provide self contained power source for the adjusting instrument which can be rechargeable or replaceable.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
Referring to
The forward or head end 20 of the instrument has a rigid plunger or rod 22 that may be removeably connected and carries the cushioned head on tip 24. The plunger can be interchangeable with various single or dual style forms.
A preload device, such as described in U.S. Pat. No. 6,702,836 can be preferably incorporated in the head end.
The grip portion can also be used for replaceable or rechargeable power input sources. In the case of a pneumatic device disposable or even rechargeable cartridges can be employed so that there is no feed line required.
For an electric operated instrument a rechargeable battery 30 (
In accordance with one of the important features of the present invention, the instrument is tunable. In the case of a pneumatic instrument valve adjustments may be included for controlling the amount of thrust as well as single and multiple thrusts. U.S. Pat. No. 6,503,211 may be referenced for such capabilities.
In an electric version, rheostat or push button controls can be used. Alternatively a trigger circuit that includes conventional electronic components can deliver selective power in a single pulse or multiple pulses to drive a solenoid type device 25 for generating the thrust. Such controls are generally known and available, for example, in handheld, portable battery operated tools.
The circuitry can also contain microprocessor devices for data storage such as number and duration of thrusts, for example, and the data collected can be down loadable to a computer loaded with diagnostic software and even to maintain a patent database.
Another important aspect of the present invention is that the instrument is provided with annunciation such as LED lights 26, or an LCD display 27 (
