Abstract: A robotic device comprising a support structure, a robotic arm coupled to the support structure and having a working channel extending from a proximal end to a distal end of the robotic arm, a drive system coupled to the support structure, and a tool module configured to detachably couple to the drive system, wherein the tool module comprises an elongate tool configured to be advanced through the working channel to a surgical site at the distal end of the robotic arm and subsequently removed from the robotic arm without having to withdraw the robotic arm from the surgical site, and a transmission configured to operatively connect the drive system and the elongate tool when the tool module is coupled with the drive system thereby providing for operation of the elongate tool by the drive system.

Abstract: A safety garment comprising; a garment body arranged for location on a torso of a wearer. The garment body includes openings to accommodate a wearers neck and arms and means for securing the garment to the torso of a wearer. The vest includes a space on the garment which receives and retains weights and a buoyancy apparatus providing means to allow a wearer to select a required amount of buoyancy. The vest also includes a harnessing assembly to allow attachment of the safety garment to a load line, the harnessing assembly allowing a user to be winched to safety allowing the garment to support the weight of a person wearing the garment.
