An endoscope that includes an elongated bougie, a distal tip at a distal end of the bougie and a handle at a proximal end of the bougie. The distal tip has a camera, an LED light, and a distal tip housing forming a distal tip chamber. The endoscope also has an electronic connector, such as a PCB board connector, having at least one PCB board, and at least a portion of the PCB board is nestled within the distal tip chamber. The PCB board connector is disposed between the distal tip and the distal end of the elongated bougie when being assembled. The distal tip and the PCB board connector are attached into one integral distal assembly by removable attaching means, such as a pair of snap fit hood and holder. The integral distal end assembly is configured to be cut from the old bougie used in a medical procedure and to be collected and later disassembled, sterilized, and reassembled with another new bougie.

A support device for an endoscope comprises a tubular member configured for removable attachment to an outer surface of the endoscope near, or at, its distal end and a plurality of projecting elements extending outward from the outer surface of the tubular member and circumferentially spaced from each other. The device includes an optically transparent cover coupled to the tubular member and configured for covering the distal end of the endoscope when the tubular member is attached to the outer surface of the endoscope. The projecting elements provide support for the endoscope, improve visualization and center the scope as it passes through a body lumen, such as the colon. In addition, the cover seals the distal end of the endoscope to protect the scope and its components from debris, fluid, pathogens and other biomatter.

An ultrasonic endoscope includes: an ultrasonic transducer having an ultrasonic vibrator; a distal end portion body disposed continuously with a proximal end side of the ultrasonic transducer; an erecting base housing portion that is disposed in the distal end portion body and has an opening which opens toward one side in a direction perpendicular to the axial direction of the distal end portion body; a treatment tool lead-out port that communicates with the inside of the erecting base housing portion, an erecting base that is disposed in the inside of the erecting base housing portion and changes a lead out direction of a treatment tool led out from the treatment tool lead-out port; and a cleaning communication hole that is formed in a wall surface on a side opposite to a side where the opening of the erecting base housing portion is disposed and communicates with an outside.

A medical system includes a medical device and an end cap. The medical device includes a handle, including an actuation device, and a shaft extending from the handle. A distal end of the shaft includes a tab, and the tab is movable based on movement of the actuation device. The end cap includes a modular camera assembly. The modular camera assembly includes a camera, a support, an arm, and a cavity. The tab is coupleable to the modular camera assembly via the cavity, and movement of the tab controls a position of the support and the camera.

Endoscopes of this disclosure, such as colonoscopes, provide a broader field of view and allow extended access of surgical tools, and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Methods and systems of this disclosure include for capturing and displaying still and video images using an endoscope corresponding to a left-side looking viewing element, a front-looking viewing element, and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

A sheath for a medical instrument includes an elongate body extending from a proximal end to a distal face. The elongate body may be configured to axially extend from a first length to a second length greater than the first length. The sheath may include a first hollow lumen extending from a first end proximate the proximal end to a second end proximate the distal face, and a second hollow lumen extending from the proximal end to the distal face. The second lumen may be open at the distal face. The sheath may also include a transparent window positioned at the second end of the first lumen to seal the first lumen at the second end. The transparent window may be configured to transmit light therethrough.

An endoscopic cap assembly may include a sleeve and a cap. The cap may include a cap channel extending along an external surface of the cap. The cap may also include an engagement feature extending radially outwardly from the external surface of the cap.

According to embodiments, a substantially coaxial arrangement of a camera, a light source, and an ultrasonic sensor can be positioned in an housing of a system that can be deployed from the tool port of a standard bronchoscope. Illumination from the light source facilitates positioning of the system by an operator using information from the camera. The ultrasonic system can determine when an object to be biopsied is adjacent to a biopsy needle.

An endoscope add-on assembly adapted to be attached to a target endoscope. The assembly includes an ultrasound imaging sub-assembly, including a communications cable connected to an ultrasound imaging head and an imaging head movement sub-assembly, including a conduit, holding a tension member that is attached to the ultrasound imaging head. Further included are connective elements, adapted to permit the endoscope add-on assembly to be attached to the target endoscope. Finally, the imaging head movement sub-assembly is detachable from the ultrasound imaging sub-assembly, thereby permitting the imaging head movement subassembly to be processed separately from the ultrasound imaging sub-assembly, after use.

A sliding motion transfer member (22) for the kinematic chain of an actuator mechanism of an endoscope. The sliding motion transfer member (22) has a proximal end and a distal end (21). The sliding motion transfer member (22) is adapted to receive motion activation input and to move in a sliding manner in response to said motion activation input, thereby transferring motion to an elongate motion transmission member (27) extending from the distal end (21) of the sliding motion transfer member (20). The sliding motion transfer member (22) comprises a first passage (36) adapted for receiving a proximal section of said elongate motion transmission member (20) and an adhesive.
