Abstract
A surgical robotic arm drape for enveloping a portion of a robotic arm, the drape comprising: an exterior sheet defining an elongate cavity for housing a portion of a robotic arm; and a duct defined at least in part by material integral with the exterior sheet, the duct defining a fluid path along the longitudinal extent of the cavity to channel fluid to or from a robotic arm housed within the cavity.

A surgical robotic arm drape for enveloping a portion of a robotic arm, the drape comprising:
- an exterior sheet defining an elongate cavity for housing a portion of a robotic arm;
- and
- a duct defined at least in part by material integral with the exterior sheet, the duct defining a fluid path along the longitudinal extent of the cavity to channel fluid to or from a robotic arm housed within the cavity and comprising first and second terminal openings and at least one port situated between the first and second terminal openings, the at least one port arranged to channel fluid to and from a respective at least one location on a robotic arm housed within the cavity.

A surgical robotic arm drape for enveloping a portion of a robotic arm, the drape comprising:
- an exterior sheet defining an elongate cavity for housing a portion of a robotic arm;
- and
- a duct defined in part by material integral with the exterior sheet and in part by the exterior sheet, the duct defining a fluid path along the longitudinal extent of the cavity to channel fluid to or from a robotic arm housed within the cavity

A surgical robotic apparatus, comprising:
- a surgical robotic arm;
- and
- a surgical robotic arm drape for enveloping a portion of the robotic arm, the drape comprising an exterior sheet defining an elongate cavity for housing a portion of the robotic arm;
- and
- longitudinal features operable to space the exterior sheet of the drape from an outer surface of the robotic arm when there is a negative pressure within the cavity relative to an adjacent region exterior of the cavity to define a fluid path to channel fluid to or from the robotic arm housed within the cavity.
