Abstract

A drape management assembly for a robotic surgical system includes a base portion and a grasping portion. The base portion is configured for connection to the robotic surgical system. The grasping portion extends from the base portion and defines a cavity therebetween. The cavity is configured to locate an excess portion of a drape which sheaths at least a robotic arm of the robotic surgical system.

First claim

The invention claimed is:

1. A drape management assembly for a robotic surgical system, the drape management assembly comprising:
a base portion configured for connection to the robotic surgical system, wherein the base portion includes a first prong and a second prong; and
a grasping portion extending from the base portion, the base portion and the grasping portion defining a cavity therebetween, wherein the cavity is configured to locate an excess portion of a drape which sheaths at least a robotic arm of the robotic surgical system, wherein the grasping portion includes a first jaw and second jaw each rotatably coupled to a respective one of the first prong and the second prong of the base portion, wherein in a first configuration, the first and second jaws are approximated and wherein in a second configuration, the first and second jaws are spaced apart.

2. The drape management assembly according to claim 1 , wherein the first and second jaws are resiliently biased to rotatably return to the first configuration.

3. The drape management assembly according to claim 1 , wherein each of the first and second jaws includes a first and second end, respectively, wherein the first end of each of the first and second jaws is hingedly coupled to the first and second prongs, respectively.

4. The drape management assembly according to claim 3 , wherein in the first configuration, the second ends of the first and second jaws are spaced apart a first distance, and wherein in the second configuration, the second ends of the first and second jaws are spaced apart a second distance greater than the first distance.

5. The drape management assembly according to claim 4 , wherein in the first configuration, the first distance between the second ends of the first and second jaws is configured to incrementally release the excess portion of the drape from within the cavity formed by the base portion and the grasping portion.

6. The drape management assembly according to claim 4 , wherein in the second configuration, the second distance between the second ends of the first and second jaws is configured for gathering and locating the excess portion of the drape within the cavity formed by the base portion and the grasping portion such that the excess portion of the drape is located and captured within the cavity formed by the base portion and the grasping portion when the first and second jaws are returned to the first configuration.

7. The drape management assembly according to claim 3 , wherein the second ends of the first and second jaws each include a first and second lip, respectively, wherein the first and second lips each include an end portion extending away from the second ends of the first and second jaws.

8. The drape management assembly according to claim 7 , wherein the first and second lips extend away from the cavity formed by the base portion and the grasping portion and away from one another, such that a distance between the end portions of the first and second lips is greater than a distance between the second ends of the first and second jaws.

9. The drape management assembly according to claim 7 , wherein the first and second lips extend towards the cavity formed by the base portion and the grasping portion and towards one another, such that a distance between the end portions of the first and second lips is less than a distance between the second ends of the first and second jaws.

10. The drape management assembly according to claim 9 , wherein the first and second lips are hingedly coupled to the second ends of the first and second jaws respectively, and resiliently biased to an approximated position wherein the distance between the end portions of the first and second lips is less than the distance between the second ends of the first and second jaws.

11. The drape management assembly according to claim 1 , wherein the cavity includes a first cavity formed by the base portion and the grasping portion in the first configuration, and a second cavity formed by the base portion and the grasping portion in the second configuration, the second cavity being larger than the first cavity.

12. The drape management assembly according to claim 1 , wherein the first and second prongs each include a first radius of curvature and the first and second jaws each include a second radius of curvature.

13. The drape management assembly according to claim 1 , wherein the base portion further includes a stem supporting the first and second prongs.

14. A drape management assembly for a robotic surgical system, the drape management assembly comprising:
a base portion including:
a first prong having a first end and a second end; and
a second prong having a first end and a second end, the first and second prongs coupled to one another at the respective first ends thereof;

a grasping portion including:
a first jaw having a first end and a second end; and
a second jaw having a first end and a second end, the first ends of the first and second jaws operably coupled to the second ends of the first and second prongs, respectively, wherein the base portion and the grasping portion define a cavity therebetween, wherein the cavity is configured to locate an excess portion of a drape; and

a first hinge rotatably coupling the first prong and the first jaw and a second hinge rotatably coupling the second prong and the second jaw, the first and second hinges being spring loaded such that the first and second jaws are resiliently biased to a first configuration wherein the second ends of the first and second jaws are approximated towards one another, and wherein the second ends of the first and second jaws are deflectable apart from one another against the resilient bias of the first and second jaws.

15. The drape management assembly according to claim 14 , wherein the drape is configured to enclose a robotic arm of the robotic surgical system, and the drape management assembly is configured to incrementally release the excess drape portion such that the robotic arm maintains a full range of motion while enclosed within the drape.

16. The drape management assembly according to claim 14 , wherein the base portion includes a stem having a threaded portion configured to threadably couple the drape management assembly to a robotic arm of the robotic surgical system.
