  • Publication number: 20180132710
    Abstract: A retractor includes a handle portion, a blade portion coupled to the handle portion. The blade portion is configured for insertion into an internal region of a patient. The blade portion includes a first portion configured to manipulate tissue of the patient. In an embodiment, a locator element is configured to highlight an external region of the patient to indicate to a user the location of the first portion in the internal region. In an embodiment, a signal-transmission medium is coupled to the blade portion and has a port. An overmolded camera unit has a lens and is configured to couple with the port. When the camera unit is coupled with the port, the lens is oriented to capture images of the internal region.

  • Patent number: 8529442
    Abstract: Video-based laryngoscopes having an external centrally located channel coursing from the handle to a curved blade configured to deliver an ETT to a trachea as visualized by a non-removable, or alternatively, a removable video camera and lighting unit located beneath the external channel. The channel laryngoscope may be made for single use in a patient and discarded, or be processed for re-use. Alternatively, the channel laryngoscope may have a removable video camera and lighting member located within an internal chamber that runs parallel with the external channel. In another embodiment a laryngoscope adapter may be detachably affixable to the channel laryngoscope equipped with the non-removable camera to provide a decontaminated or sterile surface to permit re-use of the channel laryngoscope without having to undergo washing or decontamination procedures.

  • Publication number: 20100261967
    Abstract: An embodiment encompassing reusable video laryngoscopes that are insertable into transparent or non-transparent disposable sheaths having clear optically clear viewing windows that receive contact with camera lens. The reusable video laryngoscopes are configured to be detachably secured by locking tabs located in the transparent or non-transparent disposable sheaths with complementary shaped posts and ledges of the video laryngoscopes. The video laryngoscopes that are secured into the transparent or non-transparent disposable sheaths may be inserted into the patient's mouth to provide clear camera viewing through the optically clear window ports of the transparent or non-transparent disposable sheaths to allow endotracheal procedures to be undertaken. The transparent or non-transparent disposable sheaths are sterilizable and may be used just once for a given patient. The video laryngoscopes in the form of a baton are detachably removeable from the disposable sheath exposed to a patient.

  • Publication number: 20090294313
    Abstract: A single-use medical equipment package cover comprising a solid preformed shell to cover the functional part of a medical instrument or surgical device and a trailing soft plastic cover or plastic sheath for the rest of the surface of the medical instrument or surgical device. The medical equipment package cover is applied in a folded or stowed configuration and is then unfolded to a deployed configuration. The trailing plastic cover may be transparent and removably affixable to a lens surface or a monitor surface. Unfolding of the removably affixed sheath imparts an interpersonal barrier to block aerial or sputum transfer between patient and medical personnel operating medical equipment being deployed on and within the patient.

  • Publication number: 20090264708
    Abstract: A multipurpose surgical platform and intubation apparatus for ENT or Surgery with a lifting bar handle, video scope passage and multiple operating channels is described. The surgical platform may have a number of configurations and methods of assembly having an operating stage to allow delivery of the relevant scopes and tools reliably and with an angulation that reduces the mechanical force required to obtain the access needed for diagnosis and therapy. Laser surgery, smoke evacuation and jet ventilation are design features provided by the single-use surgical platform and intubation apparatus.
