An endoscope reprocessing method includes: cleaning, disinfecting, or sterilizing an inside of a pipe line and an outer surface of an endoscope accommodated in a treatment tank; rinsing the outer surface of the endoscope with a rinsing liquid while filling the inside of the pipe line of the endoscope with gas; collecting a first sample from the rinsing liquid used for rinsing the outer surface of the endoscope; rinsing the inside of the pipe line of the endoscope with the rinsing liquid; and collecting a second sample from the rinsing liquid used for rinsing the inside of the pipe line of the endoscope.

An optical device includes an optical window, a gas/liquid supply nozzle that includes an opening from which gas and liquid are jetted and selectively jets the gas and the liquid to wash an effective region of the optical window, a disposition surface on which the optical window and the nozzle are disposed, and a first hydrophobic portion that has a hydrophobic surface property and is formed in a part of a region of the disposition surface present between the effective region and the nozzle and between two tangent lines intersecting with a jet direction of the nozzle and extending to be tangent to the effective region from both ends of the opening in a width direction along the disposition surface.

A tip section of a multi-camera endoscope includes a front-pointing camera on a planar surface of a distal end of the tip section and two side-pointing cameras positioned on a cylindrical surface in proximity to the planar surface such that the side field of view provided by the two side-pointing cameras partially overlaps with the front field of view provided by the front-pointing camera. The tip section further includes a working channel configured for insertion of a surgical tool; and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.

An endoscope connection tube includes a fluid feeding pipeline that has a first end portion connected to a pipe sleeve of an endoscope, and a second end portion connected to a fluid supply source; a seal portion that is provided in the first end portion of the fluid feeding pipeline, includes a close contact surface configured to closely contact the pipe sleeve to surround an opening portion of the pipe sleeve, and is configured to connect an inside of the fluid feeding pipeline and an inside of the opening portion when the close contact surface closely contacts the pipe sleeve; and a detection pipeline that has a first end portion opened in the close contact surface, and is configured to be closed by the pipe sleeve when the close contact surface is in close contact with the pipe sleeve.

A vent assembly configured to maintain predetermined positive and negative pressure differentials between gas within a compartment and the environment, such as a compartment defining an interior of an endoscope is provided. The vent assembly includes a first housing having an upper vent and a lower vent coupled to the compartment. A piston is movable from a closed position to a first position, and from the closed position to a second position. In the closed position the piston blocks the upper and lower vents. A positive pressure differential moves the piston so as to open the vent to allow gas to escape from the compartment. A negative pressure differential draws the piston from the closed position to a second position to allow gas to enter the compartment.

An endoscope-cleaning device ensures effective cleaning of an endoscope. The endoscope-cleaning device includes a long flexible core member inserted into a twisted tubular body including a weft yarn including a microfiber yarn, wherein the microfiber yarn is made of polyester and the tubular body is twisted at 5 twists/5 cm to 15 twists/5 cm.

The present invention discloses a cleaning device for a medical implement. The device comprises a receptacle member containing a cleaning agent and a detachable hollow member. The hollow member is sized for inserting within the receptacle member and at least partially submerged in the cleaning agent. The hollow member having a porous body portion adapted to receive a medical implement, for example, a cannula, and a plurality of bristle clusters arranged within the body portion adapted to engage the medical implement. The hollow member is configured to allow the medical implement to move freely and axially in engagement with bristle clusters to clean and mechanically dislodge any debris therefrom. The cleaning device further facilitates to perform an aspiration function of the cannula to draw sterile liquid through an inner portion of the cannula to flush and remove debris within the cannula.

A medical device includes a handle that includes a handle body longitudinally extending from a proximal end to a distal end; a distal connector configured to connect to a proximal end of an elongate outer member; a lumen longitudinally extending through the handle body, the lumen configured to have an elongate inner member movably disposed therein, and to permit the elongate inner member to distally extend past the distal end to within the elongate outer member and to proximally extend past the proximal end; and an inner member controller configured to longitudinally move relative to the handle body to control movement of the elongate inner member relative to the elongate outer member. The handle may be a distal handle of the medical device, which further includes a proximal handle. Both handles may control movement of the elongate inner and outer members.
