This endoscopic energy treatment instrument includes: a treatment instrument insertion part having flexibility and having a power reception part that is capacitively coupled by facing to a power transmission electrode arranged in a treatment instrument channel provided in an endoscope; a treatment part that is arranged on a distal end of the treatment instrument insertion part, and that uses electric power supplied from the power reception part to perform energy treatment; and a cleaning part that is arranged on the treatment instrument insertion part between the power reception part and the treatment part so as to be able to come into contact with the treatment instrument channel, the cleaning part being configured to clean an inside of the treatment instrument channel in accordance with a movement of the treatment instrument insertion part.

Provided among other things is a cleaning composition comprising: a carrier fluid; and Minute Fibrils suspended in the carrier fluid, wherein the composition is protein cleaning effective.

A device may be configured for white balancing a medical videoscopic camera system prior to videoscopic medical procedures, as well as optionally simultaneously or non-simultaneously applying a fog-prohibiting agent to the distal lens of a medical videoscope such as an endoscope or laparoscope. The device combines a white balancing mechanism, protective mechanism, and defogging mechanism in one simple easy to use device.

A minimally invasive device that concurrently cleans trocars or cannulas and the lens of the scope and a method of using the same is disclosed. The disclosed device may include a rod having at least one end and at least one sponge attached to at least one end of the rod. There is also disclosed a method of cleaning trocars or cannulas and the lens of a minimally invasive scope concurrently with the device. The method may include the steps of attaching a first sponge to the rod and inserting one end of the device through a trocar such that at least one sponge is in contact with the inner surface of the trocar. The device may be removed from the trocar after sufficient cleaning is performed. If the device is inserted through a different trocar, the sponge end may be used to concurrently clean a scope lens while the scope is within a body cavity.

A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endoscope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

A lens cleaning device includes: a housing shaped to fit over an end of a camera lens; a wiper movably attached to the housing, the wiper movable across the housing from a first position adjacent a first side of the housing to a second position adjacent a second side of the housing; and at least one SMA wire mechanically associated with the wiper. When the SMA wire is activated, the wiper is moved between the first position and the second position of the housing such that the wiper sweeps debris from a field of view of the camera lens.

There is provided a method of channel leakage detection in a medical device having one or more channels and a housing having an internal volume surrounding at least a portion of the one or more channels, comprising the steps of (a) pressurizing one or more of the channels by introducing air or gas into the channel; and (b) detecting leakage by monitoring pressure increase in the internal volume of the housing.

An endoscope reprocessor includes an immersion tank, a convex-shaped groove, a lid portion, a liquid supply section, a discharge port as an opening from which the liquid is discharged and which is provided at the liquid supply section, the discharge port being arranged such that a part of the opening is opposed to a side surface of the convex-shaped groove, and a control section that drives the liquid supply section to allow the liquid to be introduced into the immersion tank up to a first water level at which a flat portion of the lid portion is immersed in the liquid, and to allow the liquid to be discharged toward the flat portion and the side surface through the discharge port at the first water level.

Systems and methods for cleaning and disinfecting contaminated tube lumens are described herein. One system includes an ultraviolet light source and a sterile fluid reservoir fluidly coupled to a liquid light guide. The system is configured to allow simultaneous access and propagation of ultraviolet light and fluid in a tube having a lumen to be cleaned and disinfected. The light guide can be moved inside the tube and simultaneously emit ultraviolet light through its walls and at its distal end into the interior of the contaminated tube. A flush of sterile fluid from an open end of the liquid light guide removes debris and micro-organism detached from the inner surface during light exposure. The sterile fluid can be a high refractive index ionic solution promoting light propagation.

Systems, methods, and devices for facilitating insertion of an endotracheal tube and/or for verifying the position of the endotracheal tube within an airway of a patient with respect to an anatomical landmark of a patient are disclosed. Systems, methods, and devices for facilitating removal of debris from the distal airways of a patient under direct visualization are also disclosed.
