Abstract

Tools, systems, and methods described herein provide multiple treatments with a reduced number of tools. A single tool as described herein can be used to provide both clamping and sealing treatment modes.

First claim

What is claimed is:

1. A tool comprising:
an elongated body extending between a proximal end and a distal end, the elongated body having a longitudinal axis;
a handle coupled to the elongated body at the proximal end,
a junction between the handle and the elongated body, the junction including a spring configured to be compressed or extended in the direction of the longitudinal axis;
a pair of tips arranged at the distal end opposite the proximal end, each of the pair of tips having a corresponding fluid delivery aperture,
a fluid supply coupled to each of the delivery apertures to provide a fluid thereto,
an electrical controller configured to provide electrical power to each of the pair of tips,
a mechanical controller configured to translate the pair of tips relative to one another between a closed configuration and an open configuration, wherein the pair of tips are parallel in the closed configuration and in the open configuration, and
a housing at the distal end, the housing having a slot at a distal end of the housing, wherein the housing partially surrounds the pair of tips, wherein the pair of tips extend distally out of the slot but do not extend laterally beyond a lateral width of the housing in either the open configuration or the closed configuration, and wherein the pair of tips translate relative to one another within the slot,
wherein the tool is configured such that the spring biases the pair of tips in the open configuration.

2. The tool of claim 1 , wherein the handle includes the mechanical controller for moving the pair of tips.

3. The tool of claim 1 , wherein each tip of the pair of tips extends parallel to the other tip of the pair of tips.

4. The tool of claim 3 , wherein the mechanical controller is configured to maintain the pair of tips parallel to one another in both the open configuration and the closed configuration.

5. The tool of claim 1 wherein each tip of the pair of tips includes a flat portion.

6. The tool of claim 5 , wherein the flat portions of the pair of tips are facing one another in both the open configuration and the closed configuration.

7. The tool of claim 6 , wherein the delivery apertures are each arranged on the flat portions.

8. The tool of claim 5 , wherein the flat portion of each of the pair of tips comprises a flange extending from each of the tips.

9. The tool of claim 1 , wherein each of the pair of tips comprises at least one gripping bead.

10. A method for providing multiple treatment modes with a single device, the method comprising:
providing a device including:
an elongated body extending between a proximal end and a distal end, the elongated body having a longitudinal axis;
a handle coupled to the elongated body at the proximal end,
a junction between the handle and the elongated body, the junction including a spring configured to be compressed or extended in the direction of the longitudinal axis;
a pair of tips arranged at the distal end opposite the proximal end, each of the pair of tips having a corresponding fluid delivery aperture,
a fluid supply coupled to each of the delivery apertures to provide a fluid thereto,
an electrical controller configured to provide electrical power to each of the pair of tips,
a mechanical controller configured to translate the pair of tips relative to one another between a closed configuration and an open configuration, wherein the pair of tips are parallel to one another in the closed configuration and in the open configuration; and
a housing at the distal end, the housing having a slot at a distal end of the housing, wherein the housing partially surrounds the pair of tips, wherein the pair of tips extend distally out of the slot but do not extend laterally beyond a lateral width of the housing in either the open configuration or the closed configuration, and wherein the pair of tips translate relative to one another within the slot,
wherein the tool is configured such that the spring biases the pair of tips in the open configuration;

providing the fluid from the fluid supply at each of the delivery apertures;
providing an electrical treatment via the pair of tips to provide a sealing treatment function, and
moving the handle relative to the elongated body to overcome the spring force so as to move the pair of tips from the open configuration to the closed configuration to provide a clamping treatment function.

11. The method of claim 10 , wherein providing the fluid from the fluid supply occurs simultaneously with providing the electrical treatment.

12. The method of claim 11 , wherein providing the fluid from the fluid supply, providing the electrical treatment, and providing the clamping treatment all occur simultaneously.

13. The method of claim 10 , wherein the handle includes the mechanical controller for moving the pair of tips.

14. The method of claim 10 , wherein each tip of the pair of tips extends parallel to the other tip of the pair of tips.

15. The method of claim 14 , wherein the mechanical controller is configured to maintain the pair of tips parallel to one another in both the open configuration and the closed configuration.

16. The method of claim 10 wherein each tip of the pair of tips includes a flat portion.

17. The method of claim 16 , wherein the flat portions of the pair of tips are facing one another in both the open configuration and the closed configuration.

18. The method of claim 17 , wherein the delivery apertures are each arranged on the flat portions.

19. The method of claim 16 , wherein the flat portion of each of the pair of tips comprises a flange extending from each of the tips.

20. The method of claim 10 , wherein each of the pair of tips comprises at least one gripping bead.
