Abstract

The present disclosure provides a fluid clip for use with a coolant system for electrosurgical procedures. The fluid clip includes a clip housing having proximal and distal ends and a channel defined therethrough. The channel is dimensioned to receive tubing for carrying a cooling fluid from a cooling source. The fluid clip includes a luer that includes a passageway defined therethrough. The passageway is dimensioned to securely receive the tubing such that the tubing extends through the luer for reception within the channel defined in the clip housing. The luer includes one or more interface on a surface thereof that matingly engages a corresponding interface on the clip housing. The interface on the luer cooperates with the interface on the clip housing to limit rotation of the tubing.

Claims

1. A fluid clip for use with a coolant system, the fluid clip comprising:

a clip housing having proximal and distal ends and a channel defined therethrough, the channel configured to receive tubing for carrying a cooling fluid from a cooling source;

a luer including a passageway defined therethrough, the passageway configured to securely receive the tubing such that the tubing extends through the luer for reception within the channel defined in the clip housing, the luer including at least one interface on a surface thereof that matingly engages a corresponding interface on the clip housing to limit rotation of the tubing.

2. A fluid clip according to claim 1, wherein the interface on the luer includes a pair of opposing wings that matingly engage a corresponding pair of slots defined within the clip housing.

3. A fluid clip according to claim 1, wherein the luer includes a housing having a proximal flange that extends therefrom, the proximal flange moveable relative to the luer housing to secure the tubing within the passageway.

4. A fluid clip according to claim 3, wherein the luer includes a housing having a proximal flange that extends therefrom, the luer housing including an inner peripheral surface that is configured to crimp the proximal flange upon reception therein, which, in turn, secures tubing within the passageway.

5. A fluid clip according to claim 1, wherein the luer includes a housing having a proximal flange that extends therefrom, the proximal flange including an inner peripheral surface that forms part of the passageway, the inner peripheral surface being dimensioned to securely engage the tubing when the tubing is received therethrough.

6. A fluid clip according to claim 1, wherein the clip housing is substantially J-shaped defining a radius at the distal end thereof.

7. A fluid clip according to claim 1, wherein the distal end of the clip housing includes a mechanical interface disposed thereon that facilitates secure engagement of the tubing therein.

8. A fluid clip according to claim 7, wherein the interface at the distal end of the clip housing includes a pair of opposing flanges that cooperate to facilitate secure engagement of the tubing to the distal end of the clip housing.

9. A fluid clip according to claim 7, wherein the interface at the distal end of the housing includes a pair of opposing flanges that cooperate in an overlapping manner to facilitate secure engagement of the tubing to the distal end of the clip housing.

10. A method of preventing kinking in tubing in a cooling system, comprising the steps of:

providing a clip housing having proximal and distal ends and a channel defined therethrough and a luer including a passageway defined therethrough;

inserting a tubing into and through the passageway in the luer and securing the luer to the tubing;

inserting the tubing into and through the channel of the clip housing such that the tubing extends therefrom for engagement with an instrument;

operatively engaging mechanical interfaces on the luer with corresponding mechanical interfaces on the clip housing to limit rotation of the tubing.

11. A method according to claim 10, wherein the step of inserting the tubing into and through the passageway in the luer includes the step of crimping a portion of the luer to secure the tubing.

12. A method according to claim 11, wherein the luer of the providing step includes a luer housing having a proximal flange that extends therefrom and the step of crimping includes the step of moving one of the luer housing and the proximal flange relative to one another to crimp the tubing.

13. A method according to claim 10, further comprising the step of operatively engaging the tubing in the distal end of the clip housing.

14. A method according to claim 10, further comprising the steps of:

bending the tubing around a radius defined in the channel; and

operatively engaging the tubing in the distal end of the clip housing to secure the tubing therein.

15. A coolant delivery system for use with a microwave antenna, comprising:

at least one length of tubing having one end adapted to connect to a microwave antenna and a second end adapted to connect to a coolant reservoir configured to store at least one type of coolant;

a clip housing having proximal and distal ends and a channel defined therethrough, the channel configured to receive the at least one length of tubing; and

a luer including a passageway defined therethough, the passageway configured to securely receive the at least one length of tubing such that the tubing extends through the luer for reception within the channel defined in the clip housing, the luer further including at least one interface on a surface thereof that matingly engages a corresponding interface on the clip housing to limit rotation of the tubing.

16. The coolant delivery system according to claim 15, wherein the interface on the luer includes a pair of opposing wings that matingly engage a corresponding pair of slots defined within the clip housing.

17. The coolant delivery system according to claim 15, wherein the luer includes a housing having a proximal flange that extends therefrom, the proximal flange moveable relative to the luer housing to secure the tubing within the passageway.

18. The coolant delivery system according to claim 17, wherein the luer includes a housing having a proximal flange that extends therefrom, the luer housing including an inner peripheral surface that is configured to crimp the proximal flange upon reception therein, which, in turn, secures tubing within the passageway.

19. The coolant delivery system according to claim 15, wherein the luer includes a housing having a proximal flange that extends therefrom, the proximal flange including an inner peripheral surface that forms part of the passageway, the inner peripheral surface dimensioned to securely engage the tubing when the tubing is received therethrough.

20. The coolant delivery system according to claim 15, wherein the clip housing is substantially J-shaped defining a radius at the distal end thereof.
