Endoscopes and methods of their use, where the endoscopes provide a low profile or cross-section which facilitates introduction through small body passages, such as patient's cervix, and into body cavities, such a patient's uterus.

Method for extending battery life and a capsule endoscope using the method are disclosed. According to this method, a peak current in a current profile consumed by the capsule endoscope is identified, where the peak current is contributed by at least two sub-tasks associated with operations of the capsule endoscope and said at least two sub-tasks are performed overlapping in time. A running voltage indicating a battery output voltage at or near time instances of the peak current is determined. When the running voltage a condition caused by IR (battery internal-resistance) voltage drop, the sub-tasks are adjusted to reduce overlapping so as to reduce the peak current to a second peak current. According to another method, at least one sub-task is switched to another sub-task when the running voltage is below a threshold.

A capsule endoscope device, system and method for dynamically adjusting a color illumination spectrum. A plurality of different color groups of LEDs may emit light, recorded by an image sensor, corresponding to a plurality of different respective wavelength subranges. A driving circuit may send a driving current to independently activate each different color group of LEDs during entirely or partially non-overlapping time pulses. A single color group of LEDs is independently activated at any one time, and the plurality of different color groups of LEDs are sequentially activated in successive time pulses to simulate a white light or multi-color illumination spectrum over a plurality of the time pulses. The activation pattern of the color groups of LEDs may be dynamically adjusted, in real-time, to achieve a flexible and customizable illumination spectrum ideal for imaging a variety of different environments e.g., in the GI tract.

The present invention is generally directed toward a laryngoscope having a handle, a rigid tube, and an optical subassembly. The handle has a distal end and a proximate end. The tube is hollow and also has a distal end having a distal opening and a proximate end having a proximate opening. The optical subassembly may include a light source located within the handle, a power source located within the handle and in communication with the light source and a light carrier extending between the handle and the tube and in communication with the light source and providing light inside and along the entire length of the tube.

A bougie is disclosed with a body, and a first depth indicator and a second depth indicator on the body. The body has a first end, a second end, and at least one surface extending between the first and second ends. The first depth indicator is spaced a first distance from the first end and indicates a first predetermined depth range such that the first end is positioned a first predetermined insertion range past the mouth of the patient when the body is positioned into the mouth of the patient. The second depth indicator is spaced a second distance from the second end and indicates a second predetermined depth range such that the second end is positioned a second predetermined insertion range past the mouth when the body is positioned into the mouth of the patient.

An image processing apparatus includes a first acquisition unit that acquires a first pixel signal output from a first pixel, a second acquisition unit that acquires a second pixel signal output from a second pixel having a size smaller than that of the first pixel, a temperature detection unit that detects temperature; a composition gain determination unit that determines a composition gain corresponding to the detected temperature, and a composition unit that composes the first pixel signal and the second pixel signal multiplied by the composition gain.

A special observation image is obtained by performing an image pickup of an object to be observed illuminated with special light. Bs-image signals of the special observation image are assigned to brightness signals Y to generate a first observation image for display. Gs-image signals of the special observation image are assigned to brightness signals Y to generate a second observation image for display. The first observation image for display and the second observation image for display are automatically switched and displayed on a monitor.

This disclosure relates to the minimally invasive medical technical field, and specifically, to a device of anti-fogging endoscope system including a beam of a near-infrared light for anti-fogging, which is coupled into an endoscope imaging optical channel in combination coaxially and is transmitted to the front optical window sheet, the visible light passes through the front optical window sheet, and the near-infrared light is absorbed by the absorption characteristics of the front optical window sheet to raise the temperature of the front optical window sheet. The device is also provided with a cut filter for eliminating the impact on image quality caused by the near-infrared stray light, so that the illumination light source of the prior-art endoscope is not necessary to be changed. It is suitable to integrate the coaxial coupling module with a camera handle or adapter and is more convenient to operate the device.
