The endoscope body is inserted into a patient and the selectively steerable distal portion is used to select a desired path within the patient's body. When the endoscope body is advanced, an electronic motion controller operates the automatically controlled proximal portion to assume the selected curve of the selectively steerable distal portion. Another desired path is selected with the selectively steerable distal portion and the endoscope body is advanced again. As the endoscope body is further advanced, the selected curves propagate proximally along the endoscope body, and when the endoscope body is withdrawn proximally, the selected curves propagate distally along the endoscope body. This creates a serpentine motion in the endoscope body allowing it to negotiate tortuous curves along a desired path through or around and between organs within the body.

  • Patent number: 8721529
    Abstract: Methods and devices are provided for providing suction and/or irrigation to locations within a body cavity. In general, the methods and devices can allow instruments within a body cavity to be cleaned during a surgical procedure without having to remove the instruments from the body cavity. In one embodiment, an end effector is provided that includes an elongate body having a cleaning base formed thereon. The end effector can be configured as a modular element configured to be removably and replaceably attachable to a distal end of an elongate shaft. The cleaning base can have one or more ports formed through a surface thereof. The cleaning base can be configured to provide suction and/or irrigation through the one or more ports to clean a face of a surgical instrument seated in the cleaning base or in close proximity to the cleaning base.

  • Patent number: 8708895
    Abstract: A curving control device to which an electrically-controlled endoscope is connected has a main CPU for primarily performing curving driving control, and a monitoring CPU for monitoring whether the operating state relating to curving actions is normal or abnormal. In the event of detecting an abnormality from the monitoring CPU, the curving control device also performs processing for handling the occurrence of the abnormality, such as outputting an emergency stop through an interlock via the main CPU, turning the main power and the like of a servo driver OFF.

  • Patent number: 8696552
    Abstract: A self-contained surgical, e.g., endoscope, system. The surgical, e.g., endoscope, system may include a sterilizable shaft having a light source and/or an image capture device mounted at the distal end of the shaft or connected to the distal end of the shaft by fiber optics. The light source is a light emitting diode or an array of light emitting diodes, and may have its own power source located at the distal end of the shaft. The shaft includes a working channel, an irrigation/aspiration channel, and an electric cable. The shaft is coupled at its proximal end to a control module having a video processor and an integrally-mounted display screen for displaying image data from the image capture device. The control module may also include an irrigation/aspiration system, a control unit, and a controller. The control module is coupled to a power module. The power module includes steering motors connected to steering cables in the shaft. In addition, the power module includes drive motors and a power source.

  • Patent number: 8652031
    Abstract: A remote guidance system for a medical device is provided that is capable of use with magnetic resonance imaging and other environments with a relatively high level of electromagnetic interference. In one embodiment, a fluid control system controls delivery of fluid to a fluid conduit supplying a fluid chamber of a fluid housing. A piston disposed within the fluid chamber moves in response to a change in fluid displacement in the chamber and causes corresponding movement of the medical device within a body. In another embodiment, means are provided for controlling a connector coupled to the medical device at a location outside the body wherein movement of the connector causes a corresponding movement of the medical device. A sensor generates a signal indicative of a characteristic associated with movement of the medical device. The sensor includes an optic fiber that transmits a light wave indicative of the characteristic.

  • Patent number: 8641602
    Abstract: A steerable endoscope has an elongated body with a selectively steerable distal portion and an automatically controlled proximal portion. The endoscope body is inserted into a patient and the selectively steerable distal portion is used to select a desired path within the patient's body. When the endoscope body is advanced, an electronic motion controller operates the automatically controlled proximal portion to assume the selected curve of the selectively steerable distal portion. Another desired path is selected with the selectively steerable distal portion and the endoscope body is advanced again. As the endoscope body is further advanced, the selected curves propagate proximally along the endoscope body, and when the endoscope body is withdrawn proximally, the selected curves propagate distally along the endoscope body. This creates a serpentine motion in the endoscope body that allows it to negotiate tortuous curves along a desired path through, around, and between organs within the body.
