An imaging probe comprises a camera or endoscope with an external detector array, in which the probe is sized and shaped for surgical placement in an eye to image the eye from an interior of the eye during treatment. The imaging probe and a treatment probe 500 can be coupled together with a fastener or contained within a housing. The imaging probe and the treatment probe 500 can be sized and shaped to enter the eye through an incision in the cornea and image one or more of the ciliary body band or the scleral spur. The treatment probe 500 may comprise a treatment optical fiber or a surgical placement device to deliver an implant. A processor coupled to the detector can be configured with instructions to identify a location of one or more of the ciliary body band, the scleral spur, Schwalbe's line, or Schlemm's canal from the image.

A wide-angle optical system includes a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third lens unit having a positive refractive power. At the time of carrying out a focal-position adjustment, the second lens unit is moved. The third lens unit includes a positive single lens on an image side of a cemented surface Sc having a negative refractive power nearest to an image in the third lens unit, and has a plurality of refractive surfaces having a negative refractive power on the object side of the cemented surface Sc. The third lens unit has at least one refractive surface Sp having a positive refractive power which satisfies following conditional expression (1):

0.02<fL/Rsp<1.20  (1).

An intraoral scanning device comprises housing comprising a head configured for insertion into a patient oral cavity, the head comprising a sloped surface and an aperture for transmission of optical signals, a transparent element positioned within the aperture, wherein the transparent element is at an acute angle with respect to the sloped surface, and a defogging unit comprising a heating unit. The intraoral scanning device further comprises a protective sleeve configured to cover at least a part of the head when the protective sleeve is coupled to the housing. The protective sleeve comprises an additional aperture that aligns with the aperture and an additional transparent element in the additional aperture. A gap separates the additional transparent element from the transparent element when the protective sleeve is coupled to the housing, and heat generated by the heating unit is transferred from the heating unit to the additional transparent element despite the gap that separates the additional transparent element from the transparent element.

An endoscopic snare tool with a loop wire positioned substantially within a catheter shaft and capable of deploying from and retracting into a distal end thereof at a consistent shape and angle. The shaft may include a guide tip with bisecting bores which guides the loop wire as it deploys or retracts from a lateral position of the shaft so that a consistent shape and angle are maintained. The loop wire may be formed from a composite design or a specially-treated monofilament to further maintain the shape of the loop during reduction or expansion and may further include a torsion spring positioned at a tip of the loop wire to additionally maintain the circular shape of the loop and aid in excision of tissue.

In a first example, a nasopharyngeal mirror device includes a handle, a convex mirror configured to move with respect to the handle, and an anti-fogging device configured to reduce condensation on the convex mirror. In a second example, a method includes inserting a convex mirror of a nasopharyngeal mirror device into a mouth of a patient and moving the convex mirror with respect to a handle of the nasopharyngeal mirror device such that a tissue of interest of the patient is viewable within the convex mirror. The method also includes capturing an image of the tissue of interest with a camera of the nasopharyngeal mirror device while the tissue of interest is viewable within the convex mirror.

According to some aspects, a medical imaging system is provided. The medical imaging system includes an illumination device and a medical imaging device. The illumination device includes a first light source configured to emit first light having a wavelength range. The illumination device further includes a second light source configured to emit second light having at least one predetermined wavelength band. The at least one predetermined wavelength band is within the wavelength range. The illumination device further includes a dichroic mirror configured to attenuate a portion of the wavelength range corresponding to the at least one predetermined wavelength band and to multiplex the second light with the first light such that the portion of the wavelength range of the first light is attenuated. The light multiplexed by the dichroic mirror is emitted from the illumination device along an optical axis and irradiates an observation site. The medical imaging device includes at least one sensor configured to receive light from the observation site.

Medical imaging camera head devices and methods are provided using light captured by an endoscope system or other medical scope or borescope. Afocal light from the scope is manipulated and split by a beamsplitter. At least one polarizing optical element manipulates the polarization properties of one or both of the beams. The resulting first and second beams are passed through focusing optics to different image sensor areas to produce images with different intensity. The resulting images are combined with high dynamic range techniques.

Provided are a handle for an endoscope comprising an endoscope housing and a lens tube and wherein on the endoscope housing at least one operating element for changing a setting of the endoscope is provided, wherein the handle comprises a receiving section for receiving and retaining the endoscope and a grip section connected with the receiving section for retaining the endoscope, in which the handle further comprises at least one manipulator for operating the operating element when the handle is disposed on the endoscope, wherein the manipulator is movable relative to the receiving section and relative to the grip section, an endoscope with such a handle and a method for disposing such a handle on an endoscope.
