  • Patent number: 11213192
    Abstract: An optical scope includes a body and an elongated shaft. The shaft distal end holds an optical assembly including an imaging lens with a field of view of at least 90 degrees. An LED is coupled to the body and has an output numerical aperture (NA) providing a critical angle larger than the field of view. A first pair of fiber bundles have proximal ends receiving light from the LED with distal ends presented at the shaft distal face, and an NA providing a critical angle less than the field of view. A second pair of fiber bundles also receive light from the LED with distal ends having at the shaft distal face, and have an NA providing a critical angle at least as large as the field of view. The bundles are positioned around imaging lens such that they create a light having a desired intensity profile and properties.

    Abstract: The position of a metal marker 5 relative to an optical fiber 6 is fixed, and the metal marker 5 can be moved up close to a target site such as a thrombus. It is preferable that the position, in an optical fiber longitudinal direction, of a front-end face of the optical fiber 6 is coincident with the position, in an optical fiber longitudinal direction, of a front-end face of the metal marker 5. More specifically, since the distance between the target site and the front end of the optical fiber 6 is known by radiography, it becomes unnecessary to use a large quantity of contrast agent and irradiate a laser beam depending on skill and intuition, and therefore an effective laser beam irradiation becomes possible.

  • Patent number: 10226165
    Abstract: Optical systems for flexible and rigid endoscopes that have a low diffraction limit and small geometrical optical aberrations, the systems including an aperture stop where the diameter can be adjusted to select either higher resolution or higher depth of field. The optical systems can include a lens group either to focus on different object distances or on a fixed average object distance. The aperture stop can be adjusted to increase either depth of field or resolution dependent on the endoscopic and surgical situation. Simple symbols help the surgeon to adjust the aperture stop to these situations. The surgeon can either look around the body cavity with large depth of field but moderate overall resolution or focus on a small area with less depth of field but greater resolution. The balance between resolution and depth of field can be adjusted by an automatic image control. Fields in the image field are defined and software used in the camera controller analyzes the sharpness of the different fields.
