Abstract

A surgical kit for draining a body cavity of a patient includes a sterile enclosure, a body cavity drainage device with a sterilized drainage tube having one or more lateral openings through a side wall thereof, and a sterilized body cavity drainage tube placement tool configured to be inserted through a lateral opening of the one or more lateral openings. The body cavity drainage device and the placement tool are contained within the sterile enclosure. Methods relate to providing surgical tools for draining a body cavity of a patient.

Claims

1. A surgical kit for draining a body cavity of a patient, comprising:

a sterile enclosure;

a body cavity drainage device comprising;

a sterilized drainage tube having one or more lateral openings through a side wall thereof; and

an activation apparatus affixed to the sterilized drainage tube comprising;

a control device connected to a pinion gear;

at least one rack configured to mesh with the pinion gear;

at least one flexible member attached to the at least one rack and extending through the side wall of the sterilized drainage tube; and

a compliant locking mechanism comprising a resilient locking lever configured to resiliently rotate between a locked position and an unlocked position with a proximal end attached to a housing of the activation apparatus, and a distal end with serrations configured to engage with gear teeth of the pinion gear when the locking lever is in the locked position, wherein the resilient locking lever is located outside of a profile of the pinion gear; and

a sterilized body cavity drainage tube placement tool configured to be inserted through a lateral opening of the one or more lateral openings, wherein the drainage device and placement tool are contained within the sterile enclosure, the sterile enclosure positioned within the surgical kit.

2. The surgical kit of claim 1, wherein the activation apparatus is configured to bend the drainage tube.

3. The surgical kit of claim 2,

wherein the at least one flexible member is configured to apply tension to the body cavity drainage tube to bend the body cavity drainage tube.

4. The surgical kit of claim 1, wherein the at least one rack configured to mesh with the pinion gear comprises two racks configured to mesh with the pinion gear, and the at least one flexible member comprises two flexible members, each of the two flexible members attached to a respective one of the two racks.

5. The surgical kit of claim 1, wherein the compliant locking mechanism is configured to maintain an angular position of the control device when in the locked position and to allow rotation of the control device when in the unlocked position, and wherein the compliant locking mechanism allows rotation of the control device when in the locked position upon application of torque of at least a predetermined value to the control device.

6. The surgical kit of claim 1, further comprising a sterilized drainage tube cleaning device configured to be inserted into the body cavity drainage tube to remove an obstruction.

7. The surgical kit of claim 6, further comprising a body cavity drainage tube cleaning device, comprising:

a flexible shaft with a proximal end and a distal end;

a handle at the proximal end of the shaft; and

a cleaning instrument at the distal end of the shaft.

8. The surgical kit of claim 7, wherein the cleaning instrument comprises a resilient coil.

9. The surgical kit of claim 1, wherein each lateral opening of the plurality of lateral openings has a diameter less than an inside diameter of the body cavity drainage tube.

10. The surgical kit of claim 1, further comprising a ferrule disposed at a distal end of the body cavity drainage tube.

11. The surgical kit of claim 10, wherein the ferrule comprises an axial opening with a diameter smaller than an inside diameter of the body cavity drainage tube.

12. The surgical kit of claim 1, wherein the body cavity drainage tube placement tool comprises a handle configured to be gripped by a practitioner and a shaft extending from the handle.

13. The surgical kit of claim 12, wherein the body cavity drainage tube placement tool comprises a shoulder formed in the shaft proximate a distal end of the shaft.

14. The surgical kit of claim 12, wherein the shaft of the body cavity drainage tube placement tool comprises a curved portion proximate the distal end of the shaft.

15. The surgical kit of claim 1, further comprising a visualization device configured to facilitate placement of the body cavity drainage device within a body cavity to be drained.

16. The surgical kit of claim 15, wherein the body cavity drainage tube comprises at least one optical fiber extending through a lumen in a wall of the body cavity drainage tube.

17. The surgical kit of claim 16, wherein the visualization device comprises a camera for operable connection to the at least one optical fiber extending through the lumen in the wall of the body cavity drainage tube.

18. The surgical kit of claim 15, wherein the body cavity drainage tube placement tool comprises at least one optical fiber extending through at least one channel in a shaft of the body cavity drainage tube placement tool.

19. The surgical kit of claim 18, wherein the visualization device comprises a camera for operable connection to the at least one optical fiber extending through the at least one channel in the shaft of the body cavity drainage tube placement tool.

20. The surgical kit of claim 1, wherein the body cavity drainage device comprising a sterilized drainage tube having one or more lateral openings through a side wall thereof comprises a detachable drainage tube and an activation device configured to couple with the detachable drainage tube.

21. The surgical kit of claim 1, further comprising a hollow needle configured to create an incision into the body cavity and a guide wire configured to facilitate placement of the body cavity drainage device.

22. The surgical kit of claim 21, further comprising at least one dilator configured to expand the incision into the body cavity.

23. The surgical kit of claim 1, wherein the sterilized body cavity drainage tube placement tool comprises a channel sized to accommodate a guide wire therethrough.
