An endoscopic vessel harvesting system for surgical removal of a blood vessel to be used for coronary bypass uses endoscopic instruments for isolating and severing the vessel. An endoscopic camera in the endoscopic instruments captures images from a distal tip of the instrument within a dissected tunnel around the vessel. An image processor assembles a three-dimensional model of the tunnel from a series of images captured by the endoscopic camera. An augmented-reality display coupled to the image processor renders (e.g., visibly displays to the user in their field of view) a consolidated map representing the three-dimensional model along with a marker in association with the map indicating a current location of the distal tip.

A medical device navigation system includes a medical device assembly and a navigation device. The medical device assembly includes an adhesive patch configured to adhere to an outer surface of a patient and a tracking assembly coupled to the adhesive patch. The tracking assembly includes one or more reference markers. The navigation device is configured to receive image data representing one or more images from an imaging device. The one or more images indicate a relative position between the one or more reference markers and a treatment site in the patient. The navigation device is configured to determine, based on the image data, a percutaneous insertion path for an injection needle from an insertion point to the treatment site of the patient and output one or more parameters corresponding to the percutaneous insertion path.

Devices, systems, and methods for localized delivery of a chemotherapy, hormonal therapy, or targeted drug/biologic therapy to a target tissue area of an internal body organ of a patient. Computer systems may be used for planning and navigation in super selective drug delivery via a tracheobronchial airway. A catheter may be used to form a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin to saturate the target tissue area. The chamber is evacuated at the end of the treatment session.

A robotic system includes an instrument including an elongate shaft, a robotic manipulator configured to manipulate the elongate shaft of the instrument, and control circuitry communicatively coupled to the robotic manipulator and configured to determine a first estimated position of at least a portion of the elongate shaft of the instrument based at least in part on robotic command data, determine a second estimated position of the at least a portion of the elongate shaft of the instrument based at least in part on position sensor data, compare the first estimated position and the second estimated position, and generate a third estimated position based at least in part on the comparison of the first estimated position to the second estimated position.

Examples relate to apparatuses, methods and computer programs for controlling a microscope system, and to a corresponding microscope system. An apparatus for controlling a microscope system comprises an interface for communicating with a camera module. The camera module is suitable for providing camera image data of a head of a user of the microscope system. The apparatus comprises a processing module configured to obtain the camera image data from the camera module via the interface. The processing module is configured to process the camera image data to determine information on an angular orientation of the head of the user relative to a display of the microscope system. The processing module is configured to provide a control signal for a robotic adjustment system of the microscope system based on the information on the angular orientation of the head of the user.

An array stabilizer for a surgical system includes a pair of arms configured to extend alongside opposite sides of a portion of an array adapter, which is attachable to a rotational instrument in a manner such that the rotational instrument is rotatable about a central axis relative to the array adapter. The array adapter is configured to extend from another component of the surgical system, such that at least one of the arms of the array adapter is configured to resist rotation of the array adapter about the central axis relative to such component as the rotational instrument rotates. The array stabilizer is either rigidly integrated with such component or is coupled to such component via a coupling device.

A tracking apparatus for tracking a bone of a patient limb is provided. The tracking apparatus includes a body configured to couple to the patient limb. The body includes first and second arms each including an exterior and opposing interior surface and opposing sides connecting the exterior and interior surfaces. The tracking apparatus also includes a wing portion extending from one of the sides of the first or second arm, the wing portion sharing the interior surface of the first or second arm. The tracking apparatus also includes one or more ultrasonic sensors coupled to the interior surface of the body and the interior surface of wing portion, the one or more ultrasonic sensor being configured to transmit ultrasonic waves to and receive ultrasonic waves from the bone. The tracking apparatus also includes one or more trackable elements coupled to the body and the wing portion.
