  • Patent number: 10792040
    Abstract: A long articulating steerable clip applier affixed to a user-operated handle. A surgical jaw assembly is attached to the other end of the clip applier. The clip applier is composed of articulating phalanges that are connected end to end by pivoting links and capable of angulations relative to one another when subjected to a tensile force. Each phalange has opposing s-shaped exterior grooves that form two continuous spiral-shaped channels for holding tension wires once the phalanges are assembled. Multiple tension wires are attached to opposite ends of adjacent phalanges. When each wire is pulled, this tensile force causes the phalanges to pivot at equivalent angles with each other. As each individual phalange pivots by an equivalent angle, the sum of these angles causes the free end of the clip applier to pivot by a large angle or a cascading actuation effect.

  • Patent number: 10076235
    Abstract: A highly articulated robotic probe (HARP) is comprised of a first mechanism and a second mechanism, one or both of which can be steered in desired directions. Each mechanism can alternate between being rigid and limp. In limp mode the mechanism is highly flexible. When one mechanism is limp, the other is rigid. The limp mechanism is then pushed or pulled along the rigid mechanism. The limp mechanism is made rigid, thereby assuming the shape of the rigid mechanism. The rigid mechanism is made limp and the process repeats. These innovations allow the device to drive anywhere in three dimensions. The device can “remember” its previous configurations, and can go anywhere in a body or other structure (e.g. jet engine). When used in medical applications, once the device arrives at a desired location, the inner core mechanism can be removed and another functional device such as a scalpel, clamp or other tool slid through the rigid sleeve to perform.

  • Patent number: 9468359
    Abstract: A control apparatus for use in endoscopes or the like is provided which allows a user to work without fatigue. The control apparatus includes a proximal and distal end sections, each of which has an articulation zone, and a central section arranged therebetween, an outer hollow-cylindrical shaft, an inner cylindrical shaft, and a control element arranged between the shafts and having two or more force-transmitting longitudinal elements extending substantially from the proximal to the distal end section for coupling movement of the distal end section with movement of the proximal articulation section. The longitudinal elements are arranged in spaced-apart relation to one another at substantially regular angular distances which, as measured in a circumferential direction, are selected such that the longitudinal elements are guided without contact in a circumferential direction and optionally guided in contact with the outer and/or the inner shaft in a radial direction.
