  • Patent number: 12310684
    Abstract: An insertable robot for minimally invasive surgery includes a tube array having a guide tube housed within a straightening tube. The guide tube includes a curved working end. The guide tube may be axially translated and rotated relative to the straightening tube such that the curved working end is constrained inside the straightening tube, causing the curved working end to achieve a smaller dimension. The tube array is inserted into a working channel on an endoscope, resectoscope or trocar. Once the tube array is inserted, the curved working end of the guide tube is translated forward beyond the distal end of the working channel, allowing the curved working end to return to its pre-formed shape. A surgical tool is inserted through the guide tube for an operation. The straightening tube allows the guide tube curved working end to be temporarily straightened during insertion and removal of the tube array.

  • Patent number: 11806107
    Abstract: A highly intuitive physician input device for communication with a minimally invasive endoscopic concentric tube surgical robot. The physician input device can comprise a user interface handle assembly, a user interface linear joint assembly, a user interfaced bearing block assembly, and a user interface base assembly, and sensors distributed throughout to measure each of these axes, possibly redundantly for safety. Due to the network of sensors and encoders built in to the physician input device, it is capable of triggering a movement in the endoscopic concentric tube robot corresponding to that of the movements made on the physician input device. There are at least four movement controls the physician input device is capable of communicating to the concentric tube robot, those being translation, pan, tilt, and axial rotation. In some embodiments a fifth control includes actuation of a tool such as a gripper.

  • Publication number: 20220296225
    Abstract: A system for performing minimally invasive surgery includes a holding arm, a holding arm interface, an actuation unit detachably disposed on the holding arm interface, and an endoscopic sheath assembly disposed on the holding arm interface opposite the actuation unit. The actuation unit includes a component bay configured to receive a camera, lens and first and second removable and disposable cartridges. Each cartridge includes a concentric tube array extending therefrom, each array including at least one guide tube and a surgical tool disposed inside the guide tube. Numerous safety and communication features are disposed on the various components of the system to ensure failsafe operation and to prevent damage to equipment or harm to patients.

  • Publication number: 20220241029
    Abstract: A minimally invasive surgery device includes a guide tube with a highly-curved distal end housed within a channel. The highly-curved distal end is configured with a curvature optimized for improved triangulation in a tissue workspace. The highly-curved distal end of the guide tube extends from a curved channel inside an endoscopic device on a surgical robot. The combination of the curved channel and the highly-curved distal end of the guide tube provides improved maneuverability in the workspace. In some embodiments, the highly-curved distal end includes nitinol and shapeset to a desired curvature. The highly-curved distal ends may be curved to achieve a stable shape with repeatable performance. In some embodiments, each first and second guide tube includes a double-curvature configuration.
