An endoscope comprising: an insertion portion; a raising base provided at a distal end of the insertion portion; a wire configured to move in a raising direction to raise the raising base; a biasing element attached to the wire and configured to apply to the wire a biasing force in the raising direction; and an operation portion coupled to a proximal end of the insertion portion, the operation portion including a switching mechanism having a first state and a second state. The switching mechanism is configured to switch between the first state and the second state. In the first state, the switching mechanism prevents the biasing force from moving the wire in the raising direction and, in the second state, the switching mechanism allows the biasing force to move the wire in the raising direction.

An endoscope eyepiece grasping mechanism includes a base part with an arcuate wall portion defining a base part wall opening between the base part arcuate wall portion circumferential ends and a rotatable part with a rotatable arcuate wall portion defining a rotatable part arcuate wall opening between the rotatable arcuate wall portion circumferential ends. A path guide rotates and axially moves the rotatable part relative to the base part between an open and closes state. A biasing device acts to bias the rotatable part toward the closed state, whereby an endoscope eyepiece may be pushed through an endoscope eyepiece side opening to a coupled position in the open state and the rotatable part rotates to the closed state and moves axially toward the base to retain the eyepiece in the coupled position.

There are provided an endoscope and a treatment tool elevating mechanism capable of achieving improvement in accessibility of a cleaning brush, prevention of wear of a distal-end-portion main body, and prevention of slipping of a treatment tool into the lower side of an operating wire. When viewed in a second direction perpendicular to both the longitudinal axis of the distal-end-portion main body and a first direction perpendicular to the longitudinal axis, a wire distal end portion of the operating wire connected to a wire connection portion of a treatment tool elevator is positioned on the other direction side with respect to an elevator main body portion of the treatment tool elevator. A second wall portion of an elevator-housing-space forming member has a first wall surface at least a portion of which has a shape along the trajectory of the wire connection portion that rotates about a rotary shaft, and a second wall surface provided at a position on one direction side of the first direction with respect to the first wall surface and having a shape extending along the trajectory of the elevator main body portion that rotates about the rotary shaft. When viewed in the second direction, the second wall surface overlaps at least a portion of the wire distal end portion in the first direction.

System and method for advancing and retracting a tubular medical instrument within a body lumen and evacuating lumen material therefrom. A shaft of the medical instrument is inserted through a central bore of a probe, an evacuation adaptor, and a swivel fastener unit, respectively mounted onto a distal carriage, a central carriage, and a proximal carriage of a translation mechanism. The probe is directed toward cavity entrance of body lumen using an adjustment mechanism coupled to a translation mechanism beam. A central probe unit of probe is maintained sealingly coupled to cavity entrance by propelling distal carriage along beam. The evacuation adapter is maintained sealingly coupled to the probe by propelling central carriage along beam, concurrent with displacement of a hollow tube of probe relative to central probe unit. Lumen material is evacuated using evacuation adaptor. The medical instrument is advanced and retracted by propelling proximal carriage along beam.

A device for operatively coupling to a structure and directing gas flow and a method of use thereof are provided. The device comprises an attachment apparatus, a gas outlet nozzle, and a. housing. The attachment apparatus is configured to operatively couple to the structure. The gas outlet nozzle is configured to direct a flow of gas to a desired location. The housing is operatively coupled to the attachment apparatus and the gas flow nozzle.

Disclosed embodiments include apparatuses, systems, and methods for positioning electrodes within a body. In an illustrative embodiment, a control handle is selectively engageable with primary and secondary actuators respectively coupled with primary and secondary electrodes. At a first position, the primary and secondary actuators are movably engaged to move in concert to a second position where distal ends of the electrodes extend into a target region. At the second position, the control handle is engaged with the secondary actuator and movable independently of the primary actuator in a first direction to a third position where the distal end of the secondary electrode extends beyond the distal end of the primary electrode. At the third position, the control handle is movably engaged with the primary actuator and movable independently of the secondary actuator in a second direction to a fourth position to partially retract the distal end of the primary electrode.

A medical device includes an endoscope head which is designed to be detachably connected to endoscope tubes. The endoscope head has a longitudinal channel for receiving an endoscope tube. The longitudinal channel has a variable opening width for receiving endoscope tubes with different diameters. The endoscope head includes a clamping device in order to hold an endoscope tube inserted into the longitudinal channel in a clamped manner

A handle (4) for an endoscope (1) includes a first shell-shaped (6) housing part and a second shell shaped housing part (7) adapted for mutual engagement so as to form a housing. The shell-shaped housing parts (6, 7) include a first recess (10) and a second recess (11) so arranged and configured that when the first and second shell-shaped housing parts (6, 7) are mutually engaged, a circumferential recess is provided in the exterior surface of the housing. The handle (4) further includes a hoop (28) adapted to be received in the circumferential recess and hold the first and second shell-shaped housing parts together.

An endoscope including a handle and an insertion cord. The handle includes a Y-connector having: a first branch/socket having a first opening from which a first channel extends; a second branch/socket having a second opening from which a second channel extends; and a third branch/socket having a third opening, wherein the first channel and the second channel join each other in a third joined channel and the third joined channel extends inside the third branch or socket towards the third opening. The first channel and the third joined channel form together an instrument insertion channel of the Y-connector. The first channel is a curved channel having a curvature at least in sections inside the first branch or socket and/or the third joined channel is a curved channel having a curvature at least in sections inside the third branch or socket.

This disclosure relates generally to a container and tube set and methods for fluid delivery, and particularly an integrated container and tube set suitable for use with an endoscope to supply liquids and/or gases to the endoscope. The integrated container and tubes may include a container (e.g., water reservoir) containing a fluid and a gas, and a plurality of tubes integrally formed with the container. The integrated container may include an irrigation supply tube having a first lumen in fluid communication with the fluid, a lens wash supply tube having a second lumen in fluid communication with the fluid, a gas supply tube having a third lumen in operative communication with the gas, and an optional alternative gas supply tube having a fourth lumen in fluid communication with the gas. The lens wash supply tube and the gas supply tube may be formed as a single, multi-lumen tube.
