Inspection assembly
This invention relates to an inspection assembly comprising a light source and a lens. In particular this invention relates to the provision of a reflection surface for improving the illumination of a field of view of a wide angle camera. An inspection assembly comprises a main body having a longitudinal axis and a distal end; a lens located at the distal end; a light source positioned to illuminate an area beyond the distal end of the main body; and a reflection surface, an angle between the reflection surface and the longitudinal axis of the main body being between 10 and 70, wherein the reflection surface is positioned such that, in use, a first fraction of the light emitted by the light source is reflected by the reflection surface and a second fraction of the light emitted by the light source travels to an area beyond the distal end of the main body without being reflected by said surface.
Extended depth of focus for high-resolution optical image scanning
Methods and systems for acquiring and/or projecting images from and/or to a target area are provided. Such a method or system can includes an optical fiber assembly which may be driven to scan the target area in a scan pattern. The optical fiber assembly may provide multiple effective light sources (e.g., via a plurality of optical fibers) that are axially staggered with respect to an optical system located between the optical fiber and the target area. The optical system may be operable to focus and/or redirect the light from the multiple light sources onto separate focal planes. A composite image may be generated based on light reflected from and/or projected onto the separate focal planes. The composite image may have an extended depth of focus or field spanning over a distance between the separate focal planes while maintaining or improving image resolution.
A RIGID MEDICAL SURGERY ILLUMINATING DEVICE
The subject matter discloses a medical imaging device, comprising a rigid housing, at least two camera units located within said rigid housing, capturing images of different directions of view and a maneuver mechanism configured to change the physical orientation of a camera of the at least two camera units
Dual-view probe for illumination and imaging, and use thereof
One embodiment of the invention is directed to an imaging probe which comprises a first element supplying electromagnetic radiation in a forward path for illuminating a forward field of view of space in front of the probe, a second element supplying electromagnetic radiation in a sideways and/or rearward path for illuminating a sideways and/or back field of view of space alongside the probe and an image sensor. The probe further includes an imaging device in imaging paths imaging the forward and sideways and/or back fields of view onto the image sensor. Preferably the forward path, the sideways and/or rearward path and the imaging paths are unobstructed by any component of the probe. Preferably the forward and sideways and/or back fields of view are registered in a fixed spatial relationship relative to one another on the image sensor. This probe can also be used with existing endoscopes or laparoscopes so that it will be easily merged into current instruments of different manufacturers, making it easier and cheaper to use this product without the expense of a totally new endoscopy or laparoscope platform. This probe can also be used to image objects in inanimate environments as well, such as in containers, buildings, rooms, engines and pipes.
ENDOSCOPE APPARATUS
An auxiliary measurement light-emitting unit emits auxiliary measurement light that is planar light including at least two first feature lines. A taken image obtained through the imaging of a subject includes an intersection curve and at least two first spots that are formed at positions corresponding to first feature lines on the intersection curve. Measurement information representing the actual size of the subject is displayed in the taken image by using the positions of the first spots.
Optical instrument and articulating image sensing apparatus therefor
An imaging apparatus is adapted for use in an optical instrument having an elongated shaft with a transparent distal end portion. The imaging apparatus includes and image sensor assembly, a first articulating structure, and a second articulating structure mounted on the first articulating structure. First and second lateral side support structures at the lateral sides of the image sensor assembly are each mounted on the second articulating structure so as to position the image sensor assembly in an operating position in the instrument transparent end portion. The connection to the second articulating structure allows an articulation of the image sensor assembly about a lateral articulation axis extending transverse to the longitudinal axis of the shaft distal end portion. This lateral articulation is in addition to the ability of the first articulating structure to rotate about the longitudinal axis of the shaft distal end portion.
INTRAORAL SCANNER
An intraoral scanner includes a casing, a light source disposed in the casing, a reflection plate obliquely disposed in the casing for reflecting light of the light source to an object to be scanned through an opening of the casing, a transparent plate, and a receiver adjacent to the light source. A projection optical axis of the light source forms a first oblique angle with a receiving optical axis of the receiver. The receiver receives light after being incident to the object to be scanned and then reflected to the receiver by the reflection plate. The transparent plate is disposed between the light source and the reflection plate or covers the opening. The projection optical axis forms a second oblique angle with a norm of the transparent plate to make a reflection angle range of light reflected by the transparent plate fall outside a receiving angel range of the receiver.
Illuminated medical devices
A surgical retractor comprising a handle and a blade extending at an angle from the handle; an illumination assembly having a plurality of direct light sources provided on the blade, at least one of the light sources being angled differently relative to the blade than another one of the light sources; and a cover configured to enclose the illumination assembly, wherein the cover comprises a plurality of openings, each opening corresponding in position to a respective light source of the illumination assembly when the cover is attached to the blade.
LIGHTING DEVICE AND ENDOSCOPE HAVING THE SAME
An illuminating device and an endoscope having the same are described. The illuminating device includes a light source assembly, and the light source assembly includes a first light source, a diffusion sheet and a dichroic mirror. The diffusion sheet is disposed between the first light source and the dichroic mirror, and the diffusion sheet is used to diffuse light of the first light source.
Disinfection system
A disinfection system is provided. The disinfection system may utilize ultraviolet light and/or ozone for disinfection of infected tissue. For example the system may involve an endoscopic ultraviolet light to disinfect lung tissue. In another aspect, the system may involve a ventilator which provides ozone in small doses to disinfect the tissue. Combinations and variations are further disclosed.
