A dental mirror structure contains a body and a connector. The body includes an inspector, a connection segment, and a first air conduit. The inspector includes a lens, and the first air conduit has an inlet and an outlet adjacent to the lens. The connector is hollow and columnar, and the connector includes a second air conduit defined on a center thereof, a connection portion extending from a first end of the connector, a first stem extending from the connection portion, a second stem extending from a second end of the connector, and a fixing extension extending from the second end of the connector and surrounding the second stem. Thereby, the first stem is connected with an air supply element, the second stem is fitted with the inlet the body, and the fixing extension is connected with the connection segment.

An information processing system, including a processor comprising hardware. The processor being configured to: acquire an endoscope image from an endoscope, the endoscope image showing a papillary portion, determine route information of a lumen based on the endoscope image, the lumen being at least one of a biliary duct or a pancreatic duct, generate a display image based on a result of the determination of the route information of the lumen, the display image having a route guide image to provide guidance of a route of the lumen leading to the papillary portion superimposed on the endoscope image, and display the display image on a display.

The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.
