Disclosed herein are safety devices that are positioned on the end of a fiberoptic cable, such as those used in surgical procedures, to prevent patients and other objects from the risk of burn from light or heat emitted from the end of the cable when not connected to an optical instrument. The disclosed safety devices can be added to the ends of existing cables and/or can be included at the end of cables during manufacture. In some embodiments, the safety device replaces an existing connector at the end of a cable, and in some embodiments the safety device is added in addition to a connector at the end of the cable. In some embodiments, a slit end cover is included over an open end of an adaptor that is mounted on a distal connector of a fiberoptic cable.

A tip light laryngoscope adapted for the trans-tissue illumination during insertion of the laryngoscope, preferably in the mucosal fold between tongue base and the epiglottis referred to as the vallecula, includes a handle and a blade with a tip at the end of the blade and a distal light source at the tip to enlighten the environment in front of the tip. The tip light laryngoscope is designed to make direct contact with the mucosa.

endoscope includes an illumination source for generating a coherent laser illumination beam; an optical sensor; a multicore fiber comprising: at least one core for transferring the illumination beam from the illumination source through said at least one core to a distal end of the fiber, for illumination of a surface to be inspected; and a plurality of cores for transferring light reflected off the surface to the optical sensor; a temporal modulation sequencer for separating a specular image of the illumination beam from an image of the surface; and a processor, for processing sensed data from the optical sensor to generate the image of the surface.

A method for providing light to an endoscope includes emitting light from a plurality of light emitting diodes, filtering the light with a plurality of dichroic filter elements, collimating and mixing light received from the dichroic filter elements into a combined light, sensing the combined light at a color sensor and determining a sensed color balance of the combined light, comparing the sensed color balance with a predetermined color balance, and varying at least one power signal to control a light intensity output by at least one of the plurality of light emitting diodes so that the sensed color balance corresponds to the predetermined color balance.

The disclosure relates to an endoscopic system. The system may include a single optical fiber. The system may further include a light source which transmits light into the single optical fiber. An image sensor may be provided within the endoscopic system and disposed at a distal end of the single optical fiber. The endoscopic system may be additionally fitted with a diffuser on the distal end of the single optical fiber which outputs a light cone that is broader than an output of the single optical fiber without the diffuser.

An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared. The images are displayed to a surgeon for use in surgery.

A method for supplementing a component (20) of a medical instrument (10) by way of a plastic component comprises the steps of inserting (106) the component (20) of the medical instrument (10) into a casting mold (70) and closing (107) the casting mold (70), a first region (72) of a mold surface of the casting mold (70) being placed against the component (20) and a casting chamber (78) remaining between a second region (74) of the mold surface of the casting mold (70) and the component (20); a step of supplying (108) a liquid plastic to the casting chamber (76); and a step of coupling (111) electromagnetic radiation into the liquid plastic within the casting chamber (76) in order to trigger a solidification of the plastic and in order to form the plastic component.

A speculum for use in an otoscope, wherein the speculum (1D) comprises a body having a passageway therethrough, defining a first end with a first opening, and a second end (1F) with a second opening; the speculum further comprising a light source (1B); the body of the speculum (1D) comprising a light transmitting portion; in which the light source (1B) is coupled to the light transmitting portion at least one coupling point (1C) such that the light transmitting portion is arranged to transmit light through the body from each coupling point (1C) to the second end (1F) of the speculum.
