  • Patent number: 9925014
    Abstract: A tool apparatus and a method for actuating a tool apparatus are disclosed. The tool apparatus includes an actuator housing, and an elongate tool manipulator extending outwardly from the actuator housing and having a plurality of control links extending along a length of the tool manipulator. The control links are operable to cause movement of a distal end of the tool manipulator in response to movement of the control links in an actuating direction generally aligned with the length of the tool manipulator. The apparatus also includes a plurality of actuators, each actuator being associated with at least one of the control links and being mounted in the actuator housing to facilitate a range of travel in a transverse direction substantially orthogonal to the actuating direction, and a plurality of linkages. Each linkage is associated with one of the control links and extends between the control link and the respective actuator and is operable to transmit drive forces between the actuator and the control link.

  • Publication number: 20180049770
    Abstract: An apparatus and method for providing surgical access to a body cavity of a living animal through an access port inserted in a wall of the body cavity is disclosed. The apparatus includes a collapsible volume having an opening for sealingly receiving a surgical apparatus. The apparatus also includes an access coupler disposed at a distal end of the collapsible volume, the access coupler being operably configured to sealingly couple to an opening in the access port placing the collapsible volume in fluid communication with the body cavity. The collapsible volume is operably configured to collapse to permit the surgical apparatus to be inserted through the access coupler into the body cavity.

  • Publication number: 20160143633
    Abstract: An articulated tool positioning apparatus comprising a base member, an intermediate member, an end member and a first tool holder arranged in succession, each of the base member, intermediate member, end member and tool holder having a respective central opening. A first plurality of coupled guides id positioned between the base member and the intermediate member and a second plurality of coupled guides is positioned between the intermediate member and the end member. A third plurality of coupled guides is diposed between the end member and the tool holder. The base member, intermediate member, end member, first tool holder and first second and third pluralities of coupled guides all have a central opening and guide openings or securing points for securing pluralities of flexible control links to the base member or to an object separated from the base member.
