An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.

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.

A visualized surgical assembly is provided, characterized in that the visualized surgical assembly includes a disposable drainage tube and a functional tube for providing visualization function, the disposable drainage tube and the functional tube are connected detachable along the axial of the tube body, and the functional tube is provided with a self-destructive part for cutting the disposable drainage tube. A corresponding endoscope is also provided. The visualized surgical assembly is a combination structure of the disposable drainage tube and the functional tube which can provide visualization function. The disposable drainage tube can removable connect with the functional tube, and the functional tube can be repeated disinfection, which can reduce the cost and avoid the risk of cross infection.

An endoscope comprising an insertion section including a distal end portion, a distal end opening in a distal end surface of a distal end portion, a side opening in a side surface of the distal end portion, a suction channel located in the insertion section and extending proximally from the distal end portion, and a valve switchable between an open state and a closed state. When a first suctioning flow through the distal end opening is less than a minimum suctioning flow, the valve is in the open state and a second suctioning flow through the side opening is present, and when the first suctioning flow is more than the minimum suctioning flow, the valve is in the closed state and the second suctioning flow is absent.

An endoscope has an insertion portion with a simple configuration. The endoscope is an endoscope having an insertion portion and an operation unit connected to one end of the insertion portion. The insertion portion includes a tube provided with a plurality of channels penetrating in a longitudinal direction, an operation unit connected to one end of the tube, and a distal tip that covers another end of the tube and smoothly communicates with a part of the plurality of channels.

Disclosed here are systems and methods for collecting and/or screening of a pancreatic secretion, using a capsule endoscope comprising an imaging system and a trypsin sensor, and a tether coupled to the capsule endoscope.

A surgical console includes a drive assembly, vacuum interface, fluid transfer device, user interface, and control circuit. The drive assembly is configured to be coupled to an endoscopic tool and to be rotated by a motor. The vacuum interface is configured to apply a vacuum to the endoscopic tool. The fluid transfer device is configured to flow fluid through the endoscopic tool. The user interface is configured to receive a user input indicating at least one of instructions to rotate the endoscopic tool while applying the vacuum, or to flow fluid through the endoscopic tool. The control circuit controls at least one of the drive assembly, the vacuum interface, or the fluid transfer device based on the instructions, and is configured to cause the drive assembly to rotate the endoscopic tool while the vacuum interface applies the vacuum responsive to the user input indicating instructions to rotate the endoscopic tool.

Disclosed are access devices that can be used to safely guide instruments, such as EP ablation catheters, to a therapy site such one within the pericardial space of the heart. The access devices include integrated visualization, illumination, stabilization, and safety features in a single platform that can, for example, more safely and efficiently identify and ablate several ventricular tachycardia (VT) locations on the left ventricle of the heart.

An otoscope suction adapter is a funnel shaped suction device that attaches to both an otoscope and suction unit in order to remove foreign objects and debris from the ear canal. The distal opening is referred to as the suction tip, which passes to a suction chamber, suction tube, and suction connector. On the posterior external aspect of the device, a point of attachment exists for the attachment of an otoscope. This allows for the transmission of light and visualization through the suction tip during suctioning procedures. The suction connector serves as a point of attachment for suction tubing and a portable or wall suction device. Emergency Room physicians affix this device to an otoscope and suction unit when attempting to remove foreign objects from a patient's ear canal. Practitioners may also use this device to remove excess ear wax and debris.

Instrumentation for microendoscopic surgery comprises a retractor system including a navigated initial probe, nested retractors and a navigated final tubular retractor defining an interior passage extending between a proximal end and a distal working end. A multi-planar navigation marker including a plurality of spaced-apart, radiopaque marker bodies can be mounted to the tubular retractor at a predetermined multi-planar spatial and rotational relation to the distal working end. The retractor can optionally include systems for fluid irrigation and suction with differential activation allows for the option of maintaining a dry surgical field or a submerged surgical field depending on the surgeon's preference during various portions of the procedure. The instrumentation can also include a camera for direct viewing and navigated burrs and/or navigated osteotomes, which allow the surgeon to use direct visualization and/or information from instrument localization on multi-planar images depending on surgeon facility resources.
