  "title": "Connecting Surgical Tools with Rotational-to-Linear Motion Adapters",
  "original_title": "Adapter, extension, and connector assemblies for surgical devices",
  "summary": "This patent describes a system for connecting surgical tools, specifically an end effector to an electrosurgical instrument, by converting rotational motion into linear motion for precise control.",
  "what_it_does": "This patent provides an assembly for linking an end effector to an electrosurgical instrument. It includes an adapter assembly with first and second pusher assemblies that change rotational spinning into straight-line movement. A drive member within the adapter helps transfer this rotational motion. The assembly also features an extension assembly, which uses flexible bands to carry the straight-line movement from the adapter. Additionally, a trocar assembly within the extension also converts rotational motion into linear motion, ensuring precise control of the surgical tool. For example, this system could allow a surgeon to rotate a control knob on a handle, and have that rotation precisely translate into a forward or backward movement of a tiny cutting or grasping tool at the tip of a long, thin instrument.",
  "what_it_does_not_cover": [
    "Does not cover surgical device connections that only use purely mechanical linkages without converting rotational motion to linear motion.",
    "Does not cover systems for connecting non-electrosurgical instruments where the specific rotational-to-linear conversion mechanisms (pusher assemblies, flexible band assemblies, trocar assembly) are absent.",
    "Does not cover assemblies where linear motion is generated directly without an intermediate rotational input.",
    "Does not cover connections for surgical tools that do not involve an 'end effector' being attached to an 'electrosurgical instrument' as described.",
    "Does not cover systems that transfer motion solely through rigid rods or cables without the described flexible band assembly."

  "abstract": "An assembly including an adapter assembly and an extension assembly for connecting an end effector to an electrosurgical instrument is provided. The adapter assembly includes first and second pusher assemblies configured for converting rotational motion into linear motion and a drive member for transferring rotational motion. The extension assembly includes at least one flexible band assembly for transferring the linear motion from the adapter assembly and a trocar assembly configured for converting rotational motion into linear motion. Also provided is a connection assembly for connecting a first tubular member to a second tubular member.",
