Registration of a surgical image acquisition device (e.g. an endoscope) using preoperative and live contour signatures of an anatomical object is described. A control unit includes a processor configured to compare the real-time contour signature to the database of preoperative contour signatures of the anatomical object to generate a group of potential contour signature matches for selection of a final contour match. Registration of an image acquisition device to the surgical site is realized based upon an orientation corresponding to the selected final contour signature match.

An image processing apparatus according to a first aspect of the present invention acquires a first image and a second image in a first image acquisition mode, or a second image acquisition mode in which a second image acquisition ratio is higher than in the first image acquisition mode, on the basis of a detection result of a specific target (whether or not a specific target has been detected, what type of specific target). For example, in accordance with whether or not a specific target has been detected and the type of specific target, the first image and the second image can be acquired in the first image acquisition mode in a case where the necessity for acquiring the second image is low, whereas the first image and the second image can be acquired in the second image acquisition mode, in which the second image acquisition ratio is high, in a case where the necessity for acquiring the second image is high.

A system and methods for providing and reclaiming a single use imaging device for sterile environments is disclosed and described. The system may include a single use high definition camera used for general purpose surgical procedures including, but not limited to: arthroscopic, laparoscopic, gynecologic, and urologic procedures, may comprise an imaging device that is a sterile and designed to ensure single use. The imaging device may have a single imaging sensor, either CCD or CMOS, encased in a housing.

An enhanced flexible robotic endoscopy apparatus includes a main body and flexible elongate shaft. The main body comprises a proximal end, a distal end and a housing that extends to the proximal end and the housing comprises a plurality of surfaces and a plurality of insertion inlets which reside on at least one of the surface of the housing at the proximal end of the main body, through which a plurality of channels for endoscopy are accessible. Each of the insertion inlets has insertion axis corresponding thereto, along which flexible elongate assemblies are insertable, with the insertion axes of the insertion inlets being parallel to the central axis of the flexible elongate shaft at the proximal end of the flexible elongate shaft.

An apparatus, system and process for identifying one or more different tissue types are described. The method may include applying a configuration to one or more programmable light sources of an imaging system, where the configuration is obtained from a machine learning model trained to distinguish between the one or more different tissue types captured in image data. The method may also include illuminating a scene with the configured one or more programmable light sources, and capturing image data that includes one or more types of tissue depicted in the image data. Furthermore, the method may include analyzing color information in the captured image data with the machine learning model to identify at least one of the one or more different tissue types in the image data, and rendering a visualization of the scene from the captured image data that visually differentiates tissue types in the visualization.

An endoscope eyepiece grasping mechanism includes a base part with an arcuate wall portion defining a base part wall opening between the base part arcuate wall portion circumferential ends and a rotatable part with a rotatable arcuate wall portion defining a rotatable part arcuate wall opening between the rotatable arcuate wall portion circumferential ends. A path guide rotates and axially moves the rotatable part relative to the base part between an open and closes state. A biasing device acts to bias the rotatable part toward the closed state, whereby an endoscope eyepiece may be pushed through an endoscope eyepiece side opening to a coupled position in the open state and the rotatable part rotates to the closed state and moves axially toward the base to retain the eyepiece in the coupled position.

An endotracheal tube includes a main tubular portion including a distal end and a proximal end opposite the distal end, the main tubular portion including a central lumen at least in part defined by a wall of the main tubular portion; a wire lumen disposed within the wall of the main tubular portion, the wire lumen defined at least in part by a sidewall portion of the wire lumen and extending from about the proximal end of the main tubular portion to about the distal end of the main tubular portion; a wire disposed in the wire lumen; and one or more cutouts extending along a portion of the wall of the main tubular portion, the cutouts comprising openings in the sidewall portion of the wire lumen, wherein the cutouts are not in fluid communication with the central lumen.

A reversal system for an endoscope, the reversal system including: first and second outer achromats each comprising at least two lenses, wherein the first and second outer achromats have an outer diameter; first and second inner achromats arranged between the first and second outer achromats, wherein each of the first and second inner achromats comprises at least two lenses; and a holding sleeve for accommodating the at least two lenses of one or more of the first and second inner achromats, wherein the holding sleeve with the at least one of the first and second inner achromats is arranged between the first and second outer achromats.

An extremely small diameter endoscope includes comprises: an endoscope body having a distal end nozzle; an imaging unit disposed in the endoscope body and adapted for capturing an image; an endoscope insertion part having a proximal end portion and a projection end portion, the proximal end portion connected to the imaging unit, the endoscope insertion part passing through the distal end nozzle, the projection end portion to be positioned in a root canal of a tooth or in a periodontal pocket; and endoscope insertion part insertion means adapted for inserting the endoscope insertion part into an observation portion in the root canal of the tooth or in the periodontal pocket with an end portion of the distal end nozzle kept abutted against a surrounding portion of the observation portion.

The disclosure relates to an endoscopic light source that includes a first emitter. The first emitter may emit light of a first wavelength at a dichroic mirror which reflects the light of the first wavelength to a plurality of optical fibers. The endoscopic light source further comprises a second emitter. The second emitter may emit light of a second wavelength at a second dichroic mirror which reflects the light of the second wavelength to the plurality of optical fibers. In one embodiment, the first dichroic mirror may be transparent to the light of the second wavelength, allowing the light of the second wavelength to pass through the first dichroic mirror.
