Fluorescent imaging systems for performing an endoscopic procedure, such as a retrograde cholangiopancreatography (ERCP) procedure may include a first light source for emitting light in the visible spectrum, or light in the near infrared (NIR) spectrum, or both. A light source bandpass filter may block the emitted light in the visible spectrum, or in the NIR spectrum, or both. A first sensor may be capable of detecting the light in the visible spectrum, or the light in the NIR spectrum, or both. A sensor bandpass filter may block the detected light in the visible spectrum, or in the NIR spectrum, or both. The first or a second light source, or the first or a second sensor, or combinations thereof, may be removably disposed on a duodenoscope.

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.

A video endoscope that includes a handle with a housing and an interface portion rotatably mounted relative to the housing, and an elongate shaft with one or more electronic image sensors, wherein a proximal end section of the shaft is detachably connected to the interface portion of the handle, where the interface portion includes a first connector element electrically connected to an electric transmission element of the interface portion and the shaft includes a second connector element electrically connected to the one or more electronic image sensors, the first and second connector elements co-operating to form a detachable electrical connection, and where the handle includes an electrical connection assembly arranged at an exterior of the interface portion forming an electrical connection to at least one stationary electric and/or electronic component of the handle in a multiplicity of rotational positions of the interface portion relative to the housing.

Provided herein are imaging systems for a patient including an imaging probe and an imaging assembly. The imaging probe includes: an elongate shaft with a proximal end, a distal portion, and a lumen extending between the proximal end and the distal portion; a rotatable optical core with a proximal end and a distal end, and at least a portion of the rotatable optical core is positioned within the lumen of the elongate shaft; and an optical assembly positioned proximate the distal end of the rotatable optical core, the optical assembly configured to direct light to tissue to be imaged and collect reflected light from the tissue to be imaged. The imaging assembly is constructed and arranged to optically couple to the imaging probe. The imaging assembly is configured to emit light into the imaging probe and receive the reflected light collected by the optical assembly.

There is provided a system for cardiac electromagnetic/magnetic catheterization for diagnosing and treating blood vessels of a patient. The system having at least one electromagnetic intraluminal capsule able to force its way through a narrowing blood vessel, the capsule carrying a camera allowing visualization of blood vessels of a patient. There is a portable electromagnetic tip, where the tip pulls the electromagnetic capsule by electromagnetic force, and when the magnetic tip moves along a body of a patient and pulls the intraluminal electromagnetic capsule along with it towards a narrowing blood vessel visualized by the camera, so that the capsule then treats the narrowing site and clears the blood vessel from coronary plaque. In addition working capsule can replace diseased valve in any cardiac position for either temporary or permanent needs.

Provided are a measurement support device, an endoscope system, a processor for an endoscope system, and a measurement support method capable of easily and highly accurately measuring the size of a subject. In the measurement support device related to one aspect of the invention, the position of a spot by measurement auxiliary light is measured, and information indicating the actual size of a subject is acquired on the basis of the measurement result to create and display a marker. Moreover, an optical axis of the measurement auxiliary light has an inclination angle that is not 0 degrees with respect to an optical axis of the imaging optical system in a case where the optical axis of the measurement auxiliary light is projected on a plane including the optical axis of the imaging optical system.

An optical device may include an optical fiber having a fixed end and a free end; a first actuator positioned at a actuator position between the fixed end and the free end and configured to apply a first force on the actuator position of the optical fiber such that a movement of the free end of the optical fiber in a first direction is caused, wherein the first direction is orthogonal to a longitudinal axis of the optical fiber; and a deformable rod disposed adjacent to the optical fiber, and having a first end and a second end, wherein the first end is connected to a first rod position of the optical fiber and the second end is connected to a second rod position of the optical fiber.

An endoscope or the like that prevents crosstalk between multiple light-emitting parts is provided. An endoscope includes: an observation window that is disposed at a distal end of an insertion part; a plurality of first light-emitting parts that are disposed around the observation window; a second light-emitting part that is disposed between the first light-emitting parts and emits light at a bandwidth different from a bandwidth of light emitted by the first light-emitting parts; and a light-shielding body that is disposed between one of the first light-emitting parts and the second light-emitting part.

The present invention provides an improved visual laryngeal mask comprising a snorkel, an end of the snorkel is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. The inner wall of the snorkel longitudinally extends an imaging cavity and a cleaning channel. The imaging cavity has a built-in imaging device, and the imaging cavity and the cleaning channel protrude forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device.

An image processing unit includes a shake amount calculation section and a static image-storage control section, and the shake amount calculation section includes a shake amount-calculation processing section and an algorithm switching section. The algorithm switching section applies an algorithm varying for each image, and selects images of which the shake amounts calculated by the shake amount-calculation processing section are small. A first image and a second image, which are selected as the images of which the shake amounts are small, are stored in a static image-storage unit. A display control unit displays static images for storage.
