Abstract

The present invention pertains to a handpiece and more particular an ergonomic handpiece having two or more segments coupled together and capable of independently rotating around a longitudinal axis of the handpiece. In addition, one of the segments of the handpiece may have a tubing/cord management segment.

Claims

1. A handpiece comprising:

a first segment disposed along a longitudinal axis of the handpiece and comprising a first end, a second end, and a tubing and cord management section located on the first end; and

a second segment disposed along the longitudinal axis of the handpiece and comprising a first end and a second end, wherein the second end comprises a needle,

wherein the second end of the first segment is coupled with the first end of the second segment and the first segment and the second segment are capable of rotating independently around the longitudinal axis of the handpiece.

2. The handpiece of claim 1, wherein the second end of the first segment is coupled with the first end of the second segment via a coupler.

3. The handpiece of claim 2, wherein the coupler is a portion of the first segment or the second segment.

4. The handpiece of claim 2, wherein the coupler is a separate component coupled with the first segment and the second segment.

5. The handpiece of claim 4, wherein the coupler comprises a swivel element.

6. The handpiece of claim 1, wherein the tubing and cord management section includes at least one port.

7. The handpiece of claim 6, wherein the at least one port exits the tubing and cord management section at an angle.

8. The handpiece of claim 7, wherein the angle is between 0 degrees and 90 degrees from the longitudinal axis of the first segment.

9. The handpiece of claim 7, wherein the angle is between 0 degrees and 45 degrees from the longitudinal axis of the first segment.

10. The handpiece of claim 1, wherein the first segment is longer than the second segment.

11. The handpiece of claim 1, wherein the second segment is longer than the first segment.

12. The handpiece of claim 1, wherein the first segment comprises a curve located along a portion of the first segment.

13. The handpiece of claim 12, wherein the curve has an angle between 0 degrees and 45 degrees.

14. The handpiece of claim 1, wherein the second segment comprises a curve located along a portion of the second segment.

15. The handpiece of claim 14, wherein the curve has an angle between 0 degrees and 45 degrees.

16. The handpiece of claim 1, wherein the handpiece is a phacoemulsification handpiece.

17. The handpiece of claim 16, wherein one or more structures for activation of ultrasound is located inside the first segment, the second segment or both the first segment and the second segment.

18. The handpiece of claim 1, wherein the first segment is reusable and the second segment is disposable.

19. The handpiece of claim 1, wherein the first segment is separable from the second segment to replace the second segment.

20. The handpiece of claim 1, wherein the first segment and the second segment are each comprised of one of titanium, plastic or rubber.
