A medical valve may comprise a valve stem and an operation portion. The operation portion may include a stationary portion, a movable portion which is movable relative to the stationary portion and fixed relative to the valve stem, a seal disposed between the stationary portion and the movable portion, and a biasing member. Movement of the movable portion in a first direction may cause deformation of the biasing member, such that a restorative force of the biasing member urges movement of the movable portion in a second direction opposite the first direction. A frictional force between the seal and one of the stationary portion and the movable portion resists the movement of the movable portion in the second direction.

An access device for a minimally invasive procedure can include a port body defining an instrument channel for a medical instrument, a radial extension extending at least partially outward from the body in a radial direction. The radial extension can extend from a distal end of the port body. The radial extension can define an imaging device cavity defined therein spaced from the port body and opening distally from the radial extension. The imaging device cavity can be configured to receive an imaging device therein for providing images within a field of view that is at least partially distal of the port body.

Disclosed is an endoscope cap includes a cap body coupled to a tip end of an endoscope introduced into an interior of an organism, an expansion/contraction part provided in the cap body, and expanded or contracted through injection of air, and an air supply part that injects or suctions the air into or from the expansion/contraction part, and the air supply part expands the expansion/contraction part by injecting the air into the expansion/contraction part and the expanded expansion/contraction part bends back a target tissue in the interior of the organism when the cap body reaches the target tissue.

A multifunctional enclosure is described having an elongated sleeve configured with an enlarged opening for the insertion of an elongated member of a medical probe. The multifunctional enclosure is configured to prevent the elongated member of the medical probe from swinging and becoming damaged during transport. The multifunctional enclosure may further comprise an attachment component for securing the medical probe to the multifunctional enclosure. Furthermore, at least one vent may be configured onto the multifunctional enclosure, such as on a first end closure portion. The vent may allow for adequate flow for sterilization and/or drying.

The present invention relates to a fluid supply device for an endoscope, including: a liquid supply unit for supplying liquids to the endoscope; a gas supply unit for supplying gases to the endoscope; and a control unit for controlling operations of the liquid supply unit and the gas supply unit, wherein the control unit includes: a foot switch located on the floor of an operating room to receive control commands on the operations of the liquid supply unit and the gas supply unit from a surgeon who uses the endoscope; and a controller for selectively operating the liquid supply unit and the gas supply unit according to the control commands received.

An endoscope has a cannula, one and only one translucent or transparent cover at a distal end of the cannula, a light source and imaging system, both inside the cannula. The light source delivers light into the cover. At least some of that light passes through the cover to illuminate an inspection site inside the patient's body; some of that light is internally reflected at an outer surface of the cover to travel back toward an inner surface of the cover. The imaging system receives the light that has been reflected off the inspection site and returned to the endoscope through the cover. The components are configured such that none of the light that is internally reflected at the outer surface of the cover reaches an optical input of the imaging system directly (e.g., without being further reflected).

A catheter can include a catheter main body and a sheath that covers the catheter main body and can move along the longitudinal axis with respect to the catheter main body. An operating unit can be disposed at a proximal end portion of the sheath and can move the sheath and the catheter main body with respect to one another. The catheter main body can include a slit on an outer peripheral surface of a distal end portion and can extend along the longitudinal axis from a slit distal end to a slit proximal end side. An outside diameter of the distal end portion of the catheter main body is larger than an inside diameter of a distal end portion of the sheath when the distal end portion of the catheter main body is housed in the sheath.

The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to valve configurations providing sealable access for medical instruments to a working channel, such as a working channel for an endoscope.

A disposable laryngoscope with a disposable screw cap. The cap has a base, a perimeter sidewall extending upwardly from the base and an inner surface of the perimeter sidewall having a threads supported thereon, a cavity defined by the perimeter sidewall and base, a tube extending upwardly from the base and positioned within the cavity. A channel is provided in the cavity between an outer perimeter of the tube and the threads on the inner surface of the perimeter side wall. The disposable screw cap threadedly connects to the handle of the laryngoscope to provide access to the interior cavity of the handle.

A system includes an endoscope connector and an endoscope adapter. The endoscope connector includes a first portion. The first portion includes a first magnetic coupling element and a first planar portion that is perpendicular to an axial direction of the endoscope connector. The endoscope adapter includes a second planar portion. The second planar portion includes a second magnetic coupling element and a substantially planar surface that is perpendicular to an axial direction of the endoscope adapter. The endoscope connector is non-mechanically attachable to the endoscope adapter using the first magnetic coupling element and the second magnetic coupling element. The first planar portion is alignable with the second planar portion such that: electroconductive contacts of the endoscope connector are axially aligned with electroconductive pins of the endoscope adapter and a port of the endoscope connector is axially aligned with a corresponding insertion port of the endoscope adapter.
