One embodiment provides a portable endoscope. The portable endoscope includes a case configured to enclose at least electrical components of the portable endoscope. The electrical components include a camera configured to capture video content within a body of a patient. The components include one or more lights at least partially encompassing the camera. The one or more lights are adapted to illuminate internal portions of the body of the patient. The components include a transceiver in electrical communication with the camera. The transceiver is configured to receive the video content from the camera and wirelessly transmit the video content to a computing or communications device. The components include a battery configured to provide electrical energy to the camera, the one or more lights, and the transceiver. Each of the electrical components are interchangeable within the case.

A wireless endoscope includes: a detection portion configured to detect a connection state to an endoscope body of a battery; and a control portion configured to set a replacement time operation mode of using the power from a power storage component as the power needed for the endoscopic observation and performing the endoscopic observation with lower power compared to a normal time operation mode of performing an endoscopic observation with the power from the battery, when a detection result of a non-connection state of the battery is given from the detection portion, in which the control portion restores the normal time operation mode from the replacement time operation mode when a detection result of a reconnection state to the endoscope body of the battery is given from the detection portion.

A physical assessment device includes an instrument head, an optical assembly and an adapter interface member. The instrument head includes an illumination assembly including at least one LED and a drive circuit for powering the at least one LED with a pulse width modulation (PWM) current to achieve a variable brightness of the at least one LED. The optical assembly includes a plurality of optical components disposed along an optical axis. The adapter interface member enables an image capture device to be attached to the instrument head and aligned with the optical axis. The image capture device is configured to capture images of medical targets when illuminated by the at least one LED. The drive circuit is coordinated with the image capture device to ensure that the medical targets are at least partially illuminated during the capturing of the images notwithstanding the variable brightness of the at least one LED.

A system for accessing a body cavity, such as a paranasal sinus, may include a sinus access member and a handle. The sinus access member may include a rigid support tube, a curved shape memory member slidably disposed at least partially within the rigid support tube, a flexible tube slidably disposed over at least part of the curved shape memory member, and proximal coupling end. The handle may include an engagement mechanism at a distal end for releasably attaching to the proximal coupling end of the sinus access member, a housing for gripping with a hand, a curving slider for extending and retracting the curved shape memory member, and an extension slider for extending and retracting the flexible tube relative to the curved shape memory member and the rigid support tube. The handle may be reusable, and the sinus access member may be disposable.

A system and method for instant tongue sampling and diagnosis includes acquiring a plurality of tongue images from a plurality of digital oral devices, and a current health conditions, building a diagnosis framework for diagnosing a current health condition of a user by: i) analyzing the collected tongue images with a visual recognition engine to determine tongue characteristics of each tongue captured in the tongue images, and ii) correlating the tongue characteristics with the current health condition, identifying tongue characteristics from a received image of the tongue using the visual image recognition engine, applying the diagnosis framework to the tongue characteristics of the tongue to diagnosis the current health condition of the user, and modifying a graphical user interface of the digital oral device to display a custom health report indicative of the current health condition of the user, in response to applying the diagnosis framework.

Disclosed embodiments relate to an endoscopic camera and methods for operating the camera. In one embodiment, the endoscopic camera includes a grip region to facilitate holding by a user. The camera may also include a mechanism for correcting improperly exposed video signals by modulating illumination parameters.

Various embodiments comprise endoscopes (e.g., arthroscopes) for viewing inside a cavity of a body. The endoscopes may include a tip, at least one solid-state emitter such as light emitting diode (LED), located at the distal end of the endoscope, an elongated member. The elongated member may include a plurality of lenses for transmitting light received from the tip member and an elongated conducting member for providing electric power to the solid-state emitter. The elongated conducting member may include conducting lines embedded in a flexible elongated insulating membrane. The tip member and the elongated member may be configured to dissipate heat generated by the solid-state emitter.

Method for extending battery life and a capsule endoscope using the method are disclosed. According to this method, sub-tasks associated with capturing one image using the capsule endoscope when the capsule endoscope moves through a human GI (gastrointestinal) tract after being ingested by a human subject are identified. The capsule endoscope is capable of capturing an image sequence at a first frame period, and at least two sub-tasks are performed with partial or full overlap. One or more images are captured at a second frame period by performing sub-task spreading, where the sub-task spreading spreads the sub-tasks over time to reduce or avoid the partial or full overlap for said at least two sub-tasks so as to reduce a sub-task peak current or peak current duration. The second frame period is longer than the first frame period.

A cordless endoscope assembly includes a housing, an endoscope tube and an eyepiece. Electronics are housed in the housing and operable to operate one or more light sources in the endoscope, the electronics including one or more batteries and a printed circuit board. The housing includes a connector configured to removably couple with a cannula connector of a cannula when the endoscope tube is inserted through the cannula. The cordless endoscope is a disposable single use endoscope that can optionally be sterilized with an ethylene oxide (EtO) sterilization process.
