A fluid feeding and suction apparatus includes a common conduit including an endoscopic connection end and a second end, a fluid feeding conduit in fluid communication with the common conduit via the branching connector, a fluid suction conduit in fluid communication with the common conduit via the branching connector, a fluid feeding container connected to the fluid feeding conduit, a fluid suction container connected to the fluid suction conduit, a gas feeding conduit connected to the fluid feeding container, a gas suction conduit connected to the fluid suction container, and a pump connected to the gas feeding conduit and the gas suction conduit. The second end connected to a branching connector. The pump is configured to feed a supply gas to the gas feeding conduit and to suction a suction gas from the gas suction conduit.

An endoscope including: a handle, a distal tip unit, an endoscope shaft connecting the handle and the distal tip unit, a working channel provided in the endoscope shaft, and a suction valve configured to control a suction through the working channel and having a valve closed state and a valve open state. The suction valve includes a housing having an inlet opening connected to the working channel and an outlet opening; and a piston unit inserted in the housing. The piston unit comprises a movable piston, a button attached to the piston, a fixation ring arranged stationary in the housing and a spring arranged and acting between the fixation ring and the button or piston. The button is a one-piece or integral part having an integrated sealing portion contacting the housing and providing a sealing between the button and the housing in the valve open state.

A method is provided for reprocessing an internal channel of a medical device with a reprocessing system having a valve, a fluid line fluidly coupled with the valve, and at least one sensor coupled with the fluid line. The method includes performing an actuation of the valve to direct liquid through the fluid line and into the internal channel, and detecting with the at least one sensor a predetermined condition within the fluid line while the liquid is being directed into the internal channel. In response to detecting the predetermined condition, a time duration measured from the actuation of the valve is recorded. The method further includes purging the liquid from the internal channel, and directing liquid through the fluid line and into the internal channel for the time duration.

According to one aspect, a handle assembly for a medical device may comprise a handle body; and an actuator for controlling a supply of air and a supply of liquid to the medical device. The actuator may comprise a button including a hole extending through a top surface of the button, and the hole may be offset from a center of the top surface of the button. The actuator may be configured to: supply air to the medical device when a user covers the hole; and/or supply liquid to the medical device when a user presses the button.

According to one aspect, a handle assembly for a medical device may comprise a handle body; and an actuator for controlling a supply of air and a supply of liquid to the medical device. The actuator may comprise a button including a lumen extending through the button; an interior body coupled to the button, wherein a first channel of the interior body is fluidically connected to the lumen; and an exterior body coupled to the handle body, wherein the interior body is received by the exterior body. The actuator is operable at a plurality of different positions along a circumference of the handle body, and the actuator is configured to: supply air to the medical device when a user covers the lumen; and/or supply liquid to the medical device when a user presses the button.

An endoscope for the minimal invasive examination or surgical treatment of a patient has a flexible tubular shaft for insertion into the patient, a grip attached to a proximal end of the shaft for holding the endoscope, and at least one hollow tube. The shaft has at least one groove extending axially along an outer face of the shaft and in which the tube is removably housed. The tube has at least one working channel for guiding a surgical instrument, and/or carrying water or air to or providing suction at the shaft distal end. The shaft groove and the tube are dimensioned relative one another such that at least one free section of the tube is afforded play in the groove. In the straight extended state of the shaft, the at least one free section has an exterior cross-section which is slightly smaller than an interior cross-section of the groove.

An insertion device includes an insertion portion having an outer peripheral surface and configured to be inserted into a subject, and a suction pipeline provided on the outer peripheral surface of the insertion portion. The suction pipeline is switchable from a first state to a second state and the suction pipeline is configured to maintain the second state. In the first state, a distal end of the suction pipeline is folded, and in the second state, the distal end of the suction pipeline is unfolded.

A fluid delivery system may be positioned relative to a scope to assist in cleaning a scope and/or lavaging a portion of a subject during a procedure. The fluid delivery system may include a sleeve positioned over a portion of a scope. The sleeve may include passages and/or define passages relative to the scope.

An embodiment of the invention is an endoscopy system with newly designed docking block, brake control, wire tension adjustment, bending angle sensor, memory chip data storage, valve control, imaging lens cleaning, optimized lumen arrangement and distal position sensor. The docking block can have a one-touch retaining mechanism. Braking control can be accessed by the endoscopist at the hand grip or knobs. Wire tension can be relaxed or tightened in response to surgeon or endoscopist control. Bending angle sensors can protect surgical instruments. Memory chip can store usage data of the endoscope. Multiple valves can have priority control. Lenses can be cleaned with one touch of a button. Lumens can be arranged to maximize imaging and lighting angles. Position markers accompanied with sensors can position the distal end of the endoscope automatically in the optimal position.

A disposable air/water valve for an endoscope, including a shaft having a passage from an opening to a vent. The shaft has grooves and ridges and a protrusion formed at the vent. Seals are set within some of the grooves. An inner ring, having a diaphragm, extends from an outer circumference of the inner ring to an internal circumference of an outer cap. Hinges extend vertically downward from the diaphragm and ribs are formed along the internal circumference of the outer cap. A button cap has an internal ring that securely attaches to the shaft. A resilient member is securely disposed between the button cap and the diaphragm. The outer cap, inner ring, and internal ring of the button cap define a central bore to accommodate the shaft therein.
