A medical device includes a handle portion downwardly extending from an examination portion. The handle portion has opposing upper and lower open ends and a through cavity extending therebetween. An illumination assembly mounted within the open upper end of cavity includes a housing, at least one battery disposed within the housing, and an LED disposed at the distal end of an arm extending from the housing. The housing is mounted through the open upper end of the through cavity. According to at least one version, the at least one battery can be removed without removing the housing from the handle portion. The extending arm is supported by the examination portion and configured to provide illumination to a medical target. The medical device can include a vaginal speculum, sigmoidoscope, laryngoscope, anoscope, or other hand-held medical device.

A light source for an endoscope system includes a receptacle for receiving a first end of a light guide cable, a light engine with at least one LED configured to provide light transmitted from the first end of the light guide cable to a second end of the light guide cable connected to an endoscope, and a light output controller configured to adjust an intensity level of the light engine according to a set intensity level when an imaging mode is selected and at least one auxiliary mode to indicate to the user a status of the system such as a standby mode, a disconnected light guide cable, or additional statuses related to the functioning of the endoscope system.

A camera head includes an airtight case which includes an image pickup unit having an image pickup device and the like as a heat source in an inner portion and includes a partition wall to secure air-tightness with respect to an outside of the airtight case, a heat transfer sheet which connects the heat source and an inner surface of the partition wall to transfer heat generated at the heat source to the partition wall, a heat sink arranged on an outer side of the partition wall of the airtight case, and a spring member which is interposed between an outer surface corresponding to the inner surface of the partition wall of the airtight case connected to the heat transfer sheet and the heat sink to transfer heat from the outer surface of the partition wall to the heat sink.

A camera head includes a mounting unit detachably connected to an eyepiece unit of an endoscope, the camera head capturing an object image emitted from the eyepiece unit. The eyepiece unit includes an abutting surface that is orthogonal to a central axis along an insertion direction of the endoscope into a subject, and the abutting surface extending over an entire circumference in a circumferential direction around the central axis. The mounting unit is connected to the eyepiece unit and is configured to relatively rotate the endoscope and the camera head around the central axis. The mounting unit includes a facing surface that faces the abutting surface, and a pressing portion that abuts the eyepiece unit and presses the eyepiece unit toward the facing surface along the central axis. The facing surface includes a projecting portion that projects toward the abutting surface and abuts the abutting surface.

Embodiments related to medical imaging devices including rigid imaging tips and their methods of use for identifying abnormal tissue within a surgical bed are disclosed. An imaging device may include a housing having a first channel and a light guide disposed at least partially in the first channel. The imaging device may also include a clamp disposed in the housing, where the clamp is configured to apply a force to a rigid exterior portion of the light guide in a clamp direction transverse to the light guide longitudinal axis to secure the light guide to the housing. The clamp may have a clamp longitudinal axis parallel to a light guide longitudinal axis.

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.

An endoscopic system including an endoscope device that outputs image data, an illumination device that illuminates a body of a patient, and circuitry that obtains, from the image data, at least two frames each captured with a different illumination state, generate, from at least two obtained frames, a composite image that has a reduced specular reflection light component with respect to at least one of the obtained frames, and generate a video signal including the composite image.

An illumination apparatus includes a light converter disposed on a distal end surface of a light guide, the light converter being configured to emit illumination light, which is generated by converting optical characteristics of primary light that is guided by the light guide, in a forward direction which is on the light converter side of the distal end surface, and in a backward direction which is on the light guide side of the distal end surface. The illumination apparatus further includes a light collector configured to collect backward illumination light into the light guide such that the backward illumination light is guided backward by the light guide, and a heat exhauster configured to convert the backward illumination light, which is guided by the light guide, to heat, and to exhaust the heat.
