A medical endoscopy/stereo colposcopy instrument is configured to selectively take stereo colposcopy images of a patient's uterus and endoscopy images of the patient's bladder or uterus. Any of the images can be white light images or images for a selected narrow wavelength band or fluorescence images. The images can be displayed individually or as spatially registered composite images to highlight selected features of the imaged anatomy. A cup-shaped device can be positioned at the patient's cervix and provided with a light source and a fluorescence camera module to monitor changes in fluorescence in response to a photoactivated substance.

A relay adapter includes a first connector configured to connect to a processor supplying a first power. The relay adapter includes a second connector configured to connect to an insertion instrument operable using a second power. The relay adapter includes a power circuit coupled to the first connector to receive the first power. The power circuit is configured to convert the first power into the second power The power circuit is coupled to the second connector for delivering the second power to the second connector. The relay adapter includes a switching circuit coupled to the power circuit. When the second connector is not connected to the insertion instrument, the switching circuit prevents the power circuit from delivering the second power to the second connector.

A laryngoscope includes a handle having an inner cavity configured to accept at least part of a syringe, the handle having (a) a syringe seat disposed at a bottom of the inner cavity, (b) a valve disposed below the inner cavity, and (c) a blade coupled to the handle, wherein the blade includes a housing connected to a camera having a lens.

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

Various embodiments are generally directed to devices, systems, and methods for controlling the flow of fluids in endoscopic systems, such as endoscopic ultrasound (EUS) enabled endoscopes. Some embodiments are particularly directed to valve sets and/or valve interface mechanisms for controlling air and water flow through a valve well for an endoscopic system. Several embodiments are directed to user interface mechanisms and techniques for enabling an operator to interact with and control endoscope valves. In one or more embodiments, manufacture of the valve sets and/or valve interface mechanisms, collectively referred to as flow controllers, may be simplified, such as to make it economical to dispose of the flow controller after a single use.

A duodenoscope protected with disposable consumables is provided. An insertion portion of a duodenoscope body (1) is covered with a cuff (3). A disposable forceps passage tube (4) is inserted into a tube of the duodenoscope body (1). A distal end of the duodenoscope body (1) is covered with an end cap (2) which is integrally connected to the cuff (3) and the disposable forceps passage tube (4). An elongated opening (2.1), which is of the same shape as the opening of a head end (1.1) of the duodenoscope body (1), is formed in a side face of the end cap (2). A forceps-lifting unit (1.2) is disposed in the head end (1.1) of the duodenoscope body (1). The end cap (2) is made of a transparent elastic material. A soft connection port (5) is disposed in the elongated opening (2.1) of the end cap (2). The soft connection port (5) is shaped like a smoking pipe and made of an elastic film. A large-orifice end of the soft connection port (5) is glued to the elongated opening (2.1) of the end cap (2), while a small-orifice end (5.2) thereof sleeves and is glued to a distal end of the disposable forceps passage tube (4). A pulley (1.4) is disposed on the head of the forceps-lifting unit (1.2), and a groove (1.5) is formed in the periphery of the pulley (1.4). The duodenoscope protected with disposable consumables can protect both the external surface of the duodenoscope and the internal surface of the tube.

An endoscope including an insertion tube for insertion into a patient's body cavity and a tip at the distal end of the insertion tube, the tip including a tip housing encapsulating an optical inspection device, a viewing window for or of the optical inspection device and a fluid spray nozzle having an outer wall providing a fluid channel surrounded by the outer wall for spraying a fluid onto the viewing window, the fluid spray nozzle having at least one fluid splitting element arranged in the fluid channel for providing a converging fluid flow out of the nozzle onto the viewing window.

An endoscope including a coupling member (19) for coupling an insertion tube of the endoscope to an endoscope handle. The coupling member includes a proximal end (21) and a distal end (22) and a passage (20) between an opening in said proximal end (21) and an opening at said distal end (22). The coupling member (19) includes surface features (24) distributed along the circumference and adapted to engage rotation preventing features within an endoscope handle. The coupling member is used in a method for assembling the endoscope.

A single extrusion triple lumen expandable device designed for obtaining tissue from the aerodigestive tract is provided. The device may have internal and external folds and a tissue collection surface for collecting a tissue sample from a body lumen, such as the nose or throat. The device includes a camera and lumens for enhanced functionality. The present invention is also directed to methods of collecting a tissue sample using the devices, described herein.

An endoscopy device is configured with a flexible cannula or tube for nasal insertion and has multiple parallel and adjacent lumens that provide sub-chambers configured to provide means to diagnose and treat Barrett's esophagus, such as by spray cryo-therapy with no further insertion of tubes. The lumens are configured to impart a small diameter with sufficient flexibility for nasal insertion into a patient's esophagus and accommodate a means any treatment modality. In the case of cryo-therapy, a lumen provides gas pressure relief, and is along the tube, with separate lumens for the delivery of a liquid freezing agent and an imaging means, which includes a source of illumination. Outer lumens may support guide wires used to steer the tube tip and aim the camera to determine the where to immobilize tip before the start of the treatment and/or to correct strictures formed in prior procedures.
