A method and apparatus for positioning a camera to capture images inside a body cavity of a patient during a medical procedure is disclosed. The apparatus includes an insertion tube, a plurality of connected linkages extending from a distal end of the insertion tube, each linkage having a threaded actuator received on a threaded end of a drive shaft extending between the threaded actuator and a proximal end of the insertion tube. The apparatus also includes a camera disposed at a distal end of the plurality of connected linkages. Each connected linkage has at least one associated movement actuated by movement of the threaded actuator in response to rotation of the drive shaft, the associated movements of the connected linkages together operable to facilitate positioning of the camera within the body cavity of the patient.

A visual tooth cleaning, grinding and polishing instrument includes a host, an oral observation instrument and a cleaning and polishing tool. The host can drive the cleaning and polishing tool and supply a power source and a control system for an illuminating system, an observation system and the oral observation instrument. A picture shot by a camera of the observation system can be transmitted to a display of the observation system in time, so as to achieve the purposes of cleaning the teeth while observing a process of cleaning the dental calculus, dental plaque and pigmentation on the surface of the teeth with the cleaning and polishing tool and the cleaning effect instantly on a mobile phone, thereby effectively cleaning, grinding and polishing the teeth. A flusher or an electric toothbrush head or other interdental cleaning tools may also be mounted on the host or the oral observation instrument.

Methods, endoscopic systems, and non-transitory, machine-readable storage media for adjusting an exposure of an endoscopic system are described. In an embodiment, the methods include emitting light with a light source into a proximal end of an endoscope light pipe; generating received light signals with a photodetector based on light received through the endoscope light pipe by the photodetector; displaying, with a display module, images based on the received light signals having a current image brightness; monitoring the received light signals for changes to the current image brightness; and adjusting a light source illuminance level, and in some embodiments a photodetector gain and exposure time, based on the current image brightness to maintain a target image brightness of the display module. In an embodiment, a brightness adjustment step size is less than a just-noticeable difference in brightness of an eye and is directly proportional to the current image brightness.

A method for manufacturing an endoscope having a tip housing may comprise the steps of moulding at least one tip housing for an endoscope by injection moulding or by multi shot injection moulding. Each tip housing may comprise an integrally formed wall defining an interior cavity and a proximal opening providing access to the interior cavity. The wall may comprise a longitudinally extending side wall portion, a distal end wall portion, and a window portion. The window portion may consist essentially of a transparent first material and form part of the side wall portion and/or the distal end wall portion. The wall may further comprise a wall surface facing the exterior of the tip housing and having a window surface of the window portion and a distally facing end surface of the distal end wall portion. The method may further comprise positioning the at least one tip housing in a treatment chamber; and applying, in the treatment chamber, a treatment formulation to provide a coating on at least the wall surface.

A support device for an endoscope comprises a tubular member configured for removable attachment to an outer surface of the endoscope near, or at, its distal end and a plurality of projecting elements extending outward from the outer surface of the tubular member and circumferentially spaced from each other. The device includes an optically transparent cover coupled to the tubular member and configured for covering the distal end of the endoscope when the tubular member is attached to the outer surface of the endoscope. The projecting elements provide support for the endoscope, improve visualization and center the scope as it passes through a body lumen, such as the colon. In addition, the cover seals the distal end of the endoscope to protect the scope and its components from debris, fluid, pathogens and other biomatter.

An image processing apparatus includes a processor including hardware. The processor is configured to: set a first acquisition condition and a second acquisition condition for a video processor configured to acquire a first image that is based on a display-purpose acquisition condition for acquiring an image for display at a frame rate for viewing and a second image that is based on an analysis-purpose acquisition condition for acquiring an image for image analysis at a frame rate that is lower than the frame rate for viewing, in a mixed manner, the first acquisition condition including the display-purpose acquisition condition, the second acquisition condition including the display-purpose acquisition condition and the analysis-purpose acquisition condition; generate support information based on an image analysis result; and control switching between the first acquisition condition and the second acquisition condition according to the image analysis result.

A medical device including a handle including an actuation device, a sheath extending from the handle and having a longitudinal axis, the sheath defining an imaging lumen extending from the handle to a distal end of the sheath, an imaging device at a distal end of the sheath, and a piezoelectric member connected to the imaging device, where movement of the piezoelectric member moves the imaging device in a first direction relative to the longitudinal axis.
