Disposable attachable light source unit for an endoscope

Номер: US20120002394A1
Автор: Andrew J. Hamel, Erik F.D. Todd, Hasan Ertas
Принадлежит: Stryker Corp

An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate, a light guide to collect light emitted from the LEDs and to couple the light into a group of optical fibers within the endoscope, and an interface to allow the light source unit to be removably attached to the endoscope at the endoscope's external light port. The LEDs therein may be overdriven by power for increased light output. When the LEDs reach their lifetime, the light source unit can be discarded.

Endoscopic vessel harvester with gyrosensor on handle for rotating camera view

Автор: Randal J. Kadykowski, Tatsunori Fujii
Принадлежит: Terumo Cardiovascular Systems Corp

An endoscopic vessel harvesting tool uses an optics system to present of a video image to a user. As the tool is manipulated around all sides of the vessel to dissect and cut surrounding tissue and side branches, the orientation of the captured image rotates. A motion tracker (e.g., gyrosensor) in the tool detects the rotation. By detecting a rotational angular velocity of the harvester handle during the harvesting procedure, the camera view orientation is compensated before display to the user. When the handle is rotated, the detected rotation is used to provide an opposite (canceling) rotation of the camera view so that a steady orientation is presented on the display. Thus, a vertically upward direction (or any other desired reference direction) remains substantially fixed in the displayed video images.

In this patent disclosure, a machine-learning-based system for automatically turning on/off a light source of an endoscope camera during a surgical procedure to ensure the safety of the surgical staff is disclosed. The disclosed system can receive a real-time video image captured by the endoscope camera, wherein the real-time video image is captured either inside the patient's body or outside of the patient's body. The system next processes the real-time video image using a first statistical classifier to classify the real-time video image as either being inside the patient's body or being outside of the patient's body. If the real-time video image is classified as being outside of the patient's body, the system next determines if the light source is turned on. If so, the system generates a control signal to immediately turn off the light source.
