  • 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: 9737365
    Abstract: The invention provides surgical or diagnostic tools and associated methods that offer user control for operating remotely within regions of the body. These tools include a proximally-located actuator for the operation of a distal end effector, as well as proximally-located actuators for articulational and rotational movements of the end effector. Control mechanisms and methods refine operator control of end effector actuation and of these articulational and rotational movements. An articulation lock allows the fixing and releasing of both neutral and articulated configurations of the tool and of consequent placement of the end effector. The tool may also include other features. A multi-state ratchet for end effector actuation provides enablement-disablement options with tactile feedback. A force limiter mechanism protects the end effector and manipulated objects from the harm of potentially excessive force applied by the operator.

  • Patent number: 8858538
    Abstract: Apparatus and methods are described allow the techniques of endoscopic and laparoscopic surgery to be combined into a minimally invasive hybrid surgical technique called NOTES-assisted laparoscopic surgery. Manual and robotic-controlled versions of a modular laparoscopic tool are described having a small diameter shaft that is delivered laparoscopically to a surgical site. Larger diameter working tips are delivered through a NOTES delivery tube inserted to the surgical site through a natural orifice and joined to the shaft of the modular laparoscopic tool. Larger diameter working tips improve the effectiveness of the modular laparoscopic tools and the number and size of laparoscopic ports used can also be reduced.
