Abstract

Device for safely and precisely causing micro-injuries to the dermis to stimulate collagen production a skim remodeling. Specifically, needles on the device pierce the epidermis and basal cell layer into the dermis. The device incorporates safety features for the operator to be able to operate the device with one hand while keeping the other had free during procedures. Additionally, the device incorporates single use safety controls to help prevent cross contamination between patients.

Claims

1. A device for stimulating collagen growth in a human, the device comprising:

an upper end including a motor;

a lower end disposable needle module comprising a lock spring and a connecting rod, the connecting rod attachable to at least one needle and when the lower end disposable needle module is detached from the upper end, the lock spring moves to a position wherein the lower end disposable needle module cannot be re-attached to the upper end; and

a coupling attached to an eccentric roller;

the eccentric roller coupled to a yolk, the yolk coupled to a bell crank, and the bell crank attachable to the connecting rod, wherein the motor turns the coupling and the eccentric roller, the eccentric roller engages the yolk to oscillate and the yolk oscillates the bell crank and the bell crank moves the connecting rod and the at least one needle.

2. The device of claim 1 wherein the at least one needle reciprocates at between 1,000-10,000 rpm.

3. The device of claim 1 wherein the at least one needle includes an adjustment for depth of penetration from 0-2.5 mm.

5. The device of claim 1 wherein the attachment comprises the steps of inserting the upper end tip into the lower end disposable needle module and twisting the upper end relative to the lower end disposable needle module to a locked position.

6. The device of claim 1 wherein the connecting rod is sealed with a bellows.

7. The device of claim 1 further comprising a power source positioned within the upper end.

8. The device of claim 7 wherein the power source is rechargeable.

9. The device of claim 1 wherein the motor provides rotary motion that is converted to reciprocating motion by the eccentric roller, the yolk, and the bell crank.

10. The device of claim 9 wherein the reciprocating motion includes a high point wherein the at least one needle is exposed beyond a tip end of the lower end disposable needle module and a low point wherein the at least one needle is retracted within the tip end of the lower end disposable needle module.

11. The device of claim 10 wherein attachment of the upper end to the lower end disposable needle module initiates software in the device to position the at least one needle at the low point.

12. The device of claim 10 wherein during power shutdown of the device, software in the device returns the at least one needle to the low point.

13. The device of claim 1 wherein the at least one needle is arranged in concentric circles.

14. The device of claims 1 and 2-6, wherein the needle is X-shaped.

15. A method for stimulating collagen growth, the method comprising:

operating the device of claim 1 using one hand and without contamination when the at least one needle penetrates skin.

4. The device of dam 1 wherein the at least one needle includes an adjustment for depth of penetration in 0.25 mm increments.
