Abstract

A fluid evacuation device is attachable to a hand-held instrument to provide the hand-held instrument with fluid evacuation capabilities. The fluid evacuation device includes a nozzle, a hose mount, and an evacuation hose. The nozzle has a receptacle that receives a portion of a hand-held instrument therein. The distal end of the nozzle has an opening therein through which fluid may be drawn into the nozzle. The fluid can pass through a flow region in the nozzle. The hose mount extends from the nozzle and connects the hose to the nozzle. The hose mount includes a passageway through which the fluid can pass from the flow region into the evacuation hose.

First claim

What is claimed is:

1. A hand-held instrument and fluid evacuation device kit, the hand-held instrument and fluid evacuation device kit comprising:
a hand-held instrument that includes a proximal end, a distal end, a power cable attached to the proximal end, and one or more user inputs;
a fluid evacuation device that is selectively attachable to the hand-held instrument, the fluid evacuation device comprising:
a nozzle having a proximal end and a distal end, the proximal end having a receptacle configured to receive a portion of the hand-held instrument therein, the distal end having an opening therein through which fluid may be drawn into the nozzle, the nozzle also having a flow region in fluid communication with the opening in the distal end, the flow region extending from the distal end toward the proximal end;
a hose mount extending proximally from the proximal end of the nozzle, the hose mount having a passageway extending therethrough, the passageway being in fluid communication with the flow region in the nozzle; and
a flexible evacuation hose connected to the hose mount such that a lumen in the evacuation hose is in fluid communication with the passageway in the hose mount; and

one or more fasteners configured to connect together the evacuation hose and the power cable of the hand-held instrument, wherein the one or more fasteners are configured to connect together at least a portion of a length of the evacuation hose and at least a portion of a length of the power cable to form a connected length of the evacuation hose and the power cable, such that the connected length of the evacuation hose and the power cable extends away from the hand-held instrument at a location between the proximal and distal ends of the hand-held instrument.

2. The fluid evacuation device of claim 1 , wherein the nozzle has a longitudinal axis extending between the proximal end and the distal end thereof.

3. The fluid evacuation device of claim 2 , wherein the flow region is disposed at an angle relative to the longitudinal axis of the nozzle.

4. The fluid evacuation device of claim 2 , wherein the hose mount is offset from the longitudinal axis of the nozzle.

5. The fluid evacuation device of claim 2 , wherein the longitudinal axis is aligned with a longitudinal axis of the hand-held instrument when the hand-held instrument is received in the receptacle.

6. The fluid evacuation device of claim 1 , wherein the hand-held instrument is selected from the group consisting of a medical instrument, a dental instrument, a soldering tool, a wood burning tool, a drill, and an adhesive applicator.

7. The fluid evacuation device of claim 1 , wherein, when the fluid evacuation device is attached to the hand-held instrument, the evacuation hose extends away from the hand-held instrument between proximal and distal ends of the hand-held instrument.

8. The fluid evacuation device of claim 1 , wherein the evacuation hose comprises a first section of flexible hose and a second section of flexible hose.

9. The fluid evacuation device of claim 8 , wherein the evacuation hose further comprises a swivel connected between the first section and the second section to enable relative rotation between the first section and the second section.

10. The fluid evacuation device of claim 1 , wherein connecting the power cable to the evacuation hose such that the connected length of the evacuation hose and the power cable extends away from the hand-held instrument at a location distal of the proximal end of the hand-held instrument substantially eliminates a torque caused by the power cable.

11. The fluid evacuation device of claim 1 , wherein a total length of the nozzle and the hose mount is between about 2 inches and about 6 inches.

12. The fluid evacuation device of claim 8 , wherein the second of flexible hose is more flexible than the first section of flexible hose.

13. A fluid evacuation device that is attachable to a hand-held instrument that includes a proximal end, a distal end, a power cable attached to the proximal end, and one or more user inputs, the fluid evacuation device comprising:
a nozzle configured to be mounted on the distal end of the hand-held instrument, the nozzle comprising a receptacle for receiving the distal end of the hand-held instrument therein and a flow region extending therethrough;
an evacuation hose connected to the nozzle, the evacuation hose having a lumen extending therethrough, the lumen being in fluid communication with the flow region in the nozzle, the evacuation hose being configured to extend away from the hand-held instrument at a location between the proximal and distal ends of the hand-held instrument; and
one or more fasteners configured to connect together the evacuation hose and the power cable at a location between the proximal and distal ends of the hand-held instrument, such that the connected portions of the evacuation hose and the power cable extend away from the hand-held instrument at a location between the proximal and distal ends of the hand-held instrument.

14. The fluid evacuation device of claim 13 , wherein the evacuation hose creates a torque of between about 0 oz. in. and about 2 oz. in. on the hand-held instrument.

15. The fluid evacuation device of claim 13 , further comprising a hose mount disposed between the nozzle and the evacuation hose.

16. The fluid evacuation device of claim 13 , wherein at least a portion of the evacuation hose is configured to be held as a handle in a user's hand and is stiff enough to stabilize the hand-held instrument.

17. The fluid evacuation device of claim 13 , wherein the evacuation hose comprises a first section of flexible hose and a second section of flexible hose.

18. The fluid evacuation device of claim 17 , further comprising a swivel connected between the first section and the second section of the evacuation hose.

19. A fluid evacuation device that is attachable to a hand-held instrument that includes a proximal end, a distal end, a midway point between the proximal and distal ends, a power cable attached to the proximal end, and one or more user inputs, the fluid evacuation device comprising:
a nozzle configured to be mounted on the distal end of the hand-held instrument, the nozzle comprising a receptacle for receiving therein the distal end of the hand-held instrument, the nozzle having a length extending between a proximal end and a distal end thereof;
a hose mount extending proximally from the nozzle, the hose mount having a passageway extending therethrough, the passageway being in fluid communication with the nozzle, the hose mount having a length extending between a proximal end and a distal end thereof;
a flexible evacuation hose comprising a first section of flexible hose and a second section of flexible hose, a first end of the first section being connected to the hose mount such that a lumen in the evacuation hose is in fluid communication with the passageway in the hose mount, the evacuation hose further comprising a swivel connected between the first section and the second section to enable relative rotation between the first section and the second section; and
one or more fasteners configured to connect together the evacuation hose and the power cable at a location between the proximal and distal ends of the hand-held instrument, such that the connected portions of the evacuation hose and the power cable extend away from the hand-held instrument at a location between the proximal and distal ends of the hand-held instrument.
