A ventilatory laryngoscope with disposable laryngoscope lens including: a laryngoscope handle and a laryngoscope lens that is connected with an extension arm of the handle; transparent lens protecting cover on the end of the lens cavity; oxygen injecting through-hole on the cover; oxygen supply pipe in seal plug connection with the through-hole, the other end connected with an oxygen source pipe; scrubbing nozzle on the cover, and a drug delivery pipe. The laryngoscope has advantages: during the trachea intubation, ventilation and oxygen supply may be achieved in the body to effectively prevent cerebral anoxia and prolong the safe time limit of the intubation, improve the success rate of cardio-pulmonary resuscitation, and provide a safe and reliable guarantee; improve intubation safety and reduce professional risk; the secreta may be removed from the cover to achieve timely rescue of critically ill patients by collecting clear glottis image and smoothly completing the intubation.

Devices for maintaining a telescope during a minimally invasive surgery (MIS) technique such as laparoscopy or thoracoscopy. A telescope maintenance assembly is comprised of a disc and a dome. The disc is absorbent and includes a central aperture. The dome is hollow and includes an inlet port, a lower protrusion, and outlet ports which abut against the disc when attached thereto. To prepare the assembly for use, the disc is secured about a proximal port of a trocar and the lower protrusion is inserted through the central aperture, and an anti-fog solution is transmitted into and through the dome to wet the disc. After the disc is wetted, the wetted disc can be used by a surgeon or assistant to wipe debris from a lens or other optical component of the telescope without needing to remove the telescope from the trocar.

A method of using an endoscopic system includes generating, by a light system, electromagnetic waves, the light system including a source of imaging light and a separate source of heating light; directing the electromagnetic waves from the light system to a window at a distal end of an endoscope; determining if the window of the endoscope is configured to allow a first portion of the electromagnetic waves to pass therethrough while absorbing a second portion of the electromagnetic waves in order to heat the window; allowing or not allowing activation of the source of heating light depending on if the window of the endoscope is determined to be configured to allow the first portion of the electromagnetic waves to pass therethrough while absorbing the second portion of the electromagnetic waves.

An endoscope, including: at least one outer shaft tube, at least one inner shaft tube disposed within the at least one outer shaft tube; a window distally hermetically sealing one of the inner shaft tube or the outer shaft tube, a heater disposed proximate to the window between the at least one outer shaft tube and the at least one inner shaft tube, a temperature sensor disposed embedded in a potting compound proximate to the window, and an encasement filled with the potting compound, the encasement at least partially surrounding the temperature sensor.

An intraoral scanning device comprises a housing having a longitudinal axis and comprising a head configured for insertion into an oral cavity of a patient, the head comprising an aperture for transmission of optical signals, a transparent element positioned within the aperture, wherein the transparent element is non-orthogonal to the longitudinal axis, and a defogging unit comprising a heating unit. A protective sleeve is configured to cover at least a part of the head and 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. The housing and the protective sleeve are configured such that 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.
