  "abstract": "An endoscopic grabber apparatus includes a proximal housing, a distal assembly, a flexible shaft extending between the proximal housing and the distal assembly, a flexible member within the flexible shaft having a distal end portion connected to the distal assembly and a proximal end portion connected to the proximal housing, and a camera within the distal assembly. A distal end portion of the flexible member is movably disposed within the distal assembly. A proximal end portion of the flexible member is connected to an actuator within the proximal housing. Actuation of the proximal end portion moves the distal end portion of the flexible member such that a protrusion extending from the distal end portion deforms to form part of a grabber. The camera is configured to capture an image including a tip portion of the protrusion. The endoscopic grabber device can include multiple protrusions configured to grab a target object",

  "description_excerpt": "The embodiments described herein relate to grabbing tools and extensible viewing devices. More specifically, embodiments described herein relate to grabbing tools having viewing capabilities including hand-operated grabbing tools combined with one or more endoscopic cameras, as well as to compact extensible viewing devices.\n\nKnown grabbing tools for allowing operators to reach, grab, and/or interact with an object via a hand-operated assistive devices are directed to performing motor functions alone, such as grabbing an object, without providing additional functionality. These devices rely on the user being able to view the target object sufficiently well with the naked eye to reach and manipulate the object, as well as the nearby environment sufficient well to navigate to the object. These tools include tools to grab items located beyond the user's reach, such as items located in tight or hard-to-reach locations. These tools also include extensible tools, such as wrenches, screw drivers and magnetic tips located at the end of an extension.\n\nMany known tools for allowing operators to view a target area, such as endoscopes or borescopes, are similarly directed to performing viewing functions alone without providing additional functionality. These devices permit a user to guide a lens or camera to a hard-to-reach area and either take pictures of the target area or send video signals to viewer device seen by the user. Such known tools include camera mounts and endoscopic viewing devices. However, such known devices often provide only viewability of the target object or target area.",
