Ergonomic tubing attachment for medical apparatus

1. A tubing attachment system for use in a medical apparatus having a handpiece and a tube to be connected proximally to the handpiece, the tubing attachment system comprising:

a tubing attachment component having a proximal end, a distal end and an external surface, the tubing attachment component comprising a proximal end portion configured to attach to the tube, a distal end portion configured to attach to the handpiece, a throughbore extending from the distal end to the proximal end, and a circumferential groove on the external surface between the proximal end portion and the distal end portion; and

a capture component comprising a frame having an internal frame surface, an external frame surface, and a frame opening for receiving the tubing attachment component, the frame comprising at least one locking protrusion extending inward from the internal frame surface;

wherein the frame and the at least one locking protrusion are configured to fit in the circumferential groove and be rotatable in the circumferential groove about the tubing attachment component when an external force is applied and to frictionally lock the tubing attachment component in a desired rotational position in the absence of such external force.

2. The tubing attachment system of claim 1 , wherein the capture component has at least three of the locking protrusions disposed on the internal frame surface of the frame with contact surfaces facing inward.

3. The tubing attachment system of claim 1 , wherein the external force is intentionally applied by a user to rotate the frame about the tubing attachment component, or is caused by coiling of the tube attached to the proximal end portion of the tubing attachment component.

4. The tubing attachment system of claim 1 , wherein coiling of the tube produces the external force, which causes the capture component to rotate about the tubing attachment component whereby the tubing attachment system self-adjusts to a neutral position to relieve the coiling of the tube.

5. The tubing attachment system of claim 1 , wherein the proximal end portion comprises a conical body transitioning into a radially outwardly extending barb for securing the tube, and the distal end portion comprises a fitting for engaging a corresponding fitting on the handpiece.

6. The tubing attachment system of claim 5 , wherein the tubing attachment component further comprises a flange between the conical body and the fitting, and the flange forms a rail of the circumferential groove.

7. The tubing attachment system of claim 1 , wherein the capture component further comprises a pair of arms extending outwardly from the external frame surface forming a channel for holding another tube.

8. The tubing attachment system of claim 1 , in combination with a medical apparatus, wherein the medical apparatus is an ultrasonic surgical apparatus.

9. A medical apparatus comprising:

a handpiece and a tube, wherein the tube is connected to the handpiece through a swivel joint which allows the tube to rotate circumferentially with respect to the handpiece without axial displacement of the tube; and

wherein the swivel joint comprises:

a tubing attachment component comprising a longitudinal throughbore and a circumferential groove on an external frame surface;

a capture component comprising a frame with a frame opening and at least one locking protrusion extending inward from an internal frame surface of the frame;

wherein at least one locking protrusion of the frame is snapped into the circumferential groove of the tubing attachment component and rotates in the circumferential groove about the tubing attachment component; and

wherein the at least one locking protrusion engaging the circumferential groove allows the tubing attachment component to rotate when an external force is applied thereto and to be fixed at a rotational position in the absence of the external force.

10. The medical apparatus of claim 9 , wherein the capture component has at least three locking protrusions extending radially inward from the internal frame surface of the frame.

11. The medical apparatus of claim 9 , wherein the tubing attachment component further comprises a flange extending from the external frame surface of the tubing attachment component.

12. The medical apparatus of claim 9 , wherein the capture component further comprises a pair of arms extending outwardly from the external frame surface forming a channel for holding another tube.

13. The medical apparatus of claim 9 , wherein the swivel joint allows the tube, when twisted, to self-adjust to a neutral position to relieve the twist of the tube.

14. The medical apparatus of claim 9 , which is an ultrasonic surgical apparatus and wherein the tube is an irrigation tube or an aspiration tube.

15. A tubing attachment system for use with an ultrasonic surgical apparatus having a handpiece and an aspiration tube to be connected proximally to the handpiece, the tubing attachment system comprising:

a tubing attachment component comprising a longitudinal throughbore and a circumferential groove on an external frame surface, the tubing attachment component comprises a proximal end portion configured to attach to the aspiration tube and a distal end portion configured to attach to the handpiece;

a capture component comprising a frame having a front side and an opposing back side and a longitudinal frame opening extending between the front side and the back side, wherein the longitudinal frame opening is defined by a plurality of locking protrusions, each locking protrusion has a proximal end and a distal free end, wherein the proximal end projects from the frame adjacent the front side and the distal free end adjacent the back side, and wherein the each locking protrusion narrows the longitudinal frame opening from the front side to the back side;

wherein the frame between the front side of the frame and the distal free ends of the plurality of locking protrusions are longitudinally held between the longitudinal extent of the circumferential groove of the tubing attachment component while allowing rotation of the capture component about the tubing attachment component; and

wherein the plurality of locking protrusions allow the capture component to rotate about the tubing attachment component when a threshold external force is applied to the tubing attachment component.

16. The tubing attachment system of claim 15 , wherein the capture component further comprises a channel at a radial position away from the longitudinal frame opening for holding one or more tubes.

17. The tubing attachment system of claim 15 , in combination with an ultrasonic surgical apparatus having a handpiece and an aspiration tube connected to the proximal end portion of the tubing attachment component.

18. The tubing attachment system of claim 15 , wherein the tubing attachment component further comprises at least one flange extending from the external frame surface of the tubing attachment component to define the longitudinal extent of the circumferential groove.

19. The tubing attachment system of claim 15 , wherein each of the locking protrusions include contact surfaces facing inwardly that extend from the proximal end to the distal free end of the locking protrusion.
