An active cannula which does more than merely maintain a passage is usable to create and / or enlarge a passage, to position a scope or instrument, to move or locate tissue, etc. The cannula can vary in size or shape as needed, intraoperatively. Because a cannula of the present invention is expandable, the surgeon can make a relatively small incision, stretch the tissue with the expandable cannula, contract the cannula and remove it, allowing the skin to come back to its unstretched condition. Thus, a smaller incision can be made to fit the same size instrument. The cannulas can assume such a non-circular shape, to fit into a natural skin opening and cause less trauma. The devices can be used to seal off a space, expand an existing space or a potential space for working or visualization, move tissue (for example, to stretch an incision), or protect tissue.

The invention relates to a method for creating a puncture wound for obtaining a sample of a body fluid from a body part in which a skin opening is created at a puncture site in the epidermis in a skin-opening step.

This procedures looks to establish a skin opening as small as possible by accessing inner organs via needle-puncture of the skin. The percutaneous technique is used in conjunction with a robotic surgical system to further enhance advantages of manual percutaneous techniques by improving precision, usability and / or shortening surgery time by removal of redundant steps.

A zipper-type wound closer attachable to the skin around a skin opening and zipped closed to pull the skin opening closed. The wound closer includes two elongated connecting strips whose feet are pre-coated with adhesive and attached to the skin around the skin opening. The edges of the wound are trimmed flush with the interior sides of connecting strips, and the strips are then zipped together by moving a slider along the connecting strips to join the strips together like a familiar zipper. The wound zipper forms a continuous, toothless seam to prevent seepage of fluid through the seam. By holding the freshly trimmed edges of the skin opening together immobile in a clean, firm, closely aligned connection, the wound closer recreates the conditions under which scar-free healing of the skin can occur naturally; useful for repairing wounds and removing existing scars.
