Personal use extracorporeal low frequency shock wave instrument and methods of using same
A treatment device includes a housing having a longitudinal axis extending between a proximal end and a distal end, a motor, a drive shaft operatively coupled to the motor, a compression spring at least partially disposed about the drive shaft, a helical cam disposed adjacent the compression spring, the helical cam having at least one discontinuity, a hammer coupled to the helical cam and moveable therewith, and a tip disposed adjacent the distal end.
1. A method of treatment, comprising:
providing a treatment device including a housing having a longitudinal axis extending between a first end and a second end, a motor disposed within the housing, a drive shaft operatively coupled to the motor, a compression spring at least partially disposed about the drive shaft, a helical cam disposed adjacent the compression spring, the helical cam having a first flat end, and a second end having at least one discontinuity, wherein the drive shaft passes through the first and second ends of the helical cam and includes at least one cam follower configured to travel along the helical cam, a hammer coupled to one of the helical cam and the drive shaft and moveable therewith, and a tip; and
striking the tip with the hammer at repeated intervals to create a shock wave.
2. The method of claim 1 , further comprising the step of rotating the drive shaft.
3. The method of claim 2 , further comprising the step of translating the helical cam along the longitudinal axis.
4. The method of claim 1 , further comprising the step of rotating the helical cam.
5. The method of claim 4 , further comprising the step of translating the drive shaft along the longitudinal axis.
6. The method of claim 1 , further comprising the step of providing a power source in the form of a rechargeable battery.
7. The method of claim 1 , further comprising the step of providing a guide template for partially covering a body part and having at least one window through which a treatment area is exposed.
8. The method of claim 7 , further comprising the step of creating the shock wave adjacent the at least one window.
9. The method of claim 7 , further comprising the step of providing a display, and providing instructions to a user during use of the treatment device via the display.
10. A method of treatment, comprising:
providing a treatment device including a housing having a longitudinal axis extending between a first end and a second end, a drive shaft operatively coupled to a motor, a compression spring at least partially disposed about the drive shaft, a helical cam disposed adjacent the compression spring, the helical cam having a first flat end, and a second end having at least one discontinuity, wherein the drive shaft passes through the first and second ends of the helical cam and includes at least one cam follower configured to travel along the helical cam, a moveable hammer, and a tip; and
repeatedly striking the tip with the hammer to create a shock wave.
