An endoscope including: a flexible sheath extending in a longitudinal direction; a rigid body portion connected to an end portion of the flexible sheath; a ferrule provided in the rigid body portion and having a connection portion; and a tube inserted into the flexible sheath and including an end portion connected to the ferrule. The tube includes: an inner resin layer having a solid structure and that extends along an entire length of the tube in the longitudinal direction; and an outer layer provided on the inner layer and including a first portion that covers at least part of an outer periphery of the connection portion and has a porous structure, and a second portion having a solid structure and that is located on a side of the first portion that is away from the end portion of the tube.

An endoscope includes: an insertion section inserted into a subject; an operating unit continuously connected to a proximal end of the insertion section; an observation unit disposed at a distal end of the insertion section, and configured to observe the subject; a treatment instrument insertion passage configured to allow insertion of a treatment instrument providing medical treatment to the subject, and project the treatment instrument from a distal end portion of the insertion section; a distal bending portion disposed at a distal end of the treatment instrument insertion passage, and configured to bend according to a raising operation of the operating unit, the distal bending portion including a tube including a super elastic alloy and including a slit formed to reduce power required for the bending operation, and being configured to raise the treatment instrument; and a coating portion provided to cover the distal bending portion.

A medical instrument includes a first elongated member including: a fluid lumen through which a fluid is flowable, an aperture opening located in a distal end surface of the first elongated member; a second elongated member including: an insertion lumen in which the first elongated member is insertable, and a discharge section through which the fluid can be discharged; and a movement section configured to form a seal between the first elongated member and the second elongated member in a state where the first elongated member is disposed in the insertion lumen of the second elongated member, the movement section being configured to allow the first elongated member and the second elongated member to move relative to each other such that the discharge section of the second elongated member is positionable on a distal side of the aperture of the first elongated member.

A medical device sheath that includes a relatively inelastic body having a proximal end longitudinally separated from a distal end and defining a first lumen, an aperture located at the proximal end in fluid communication with the lumen and configured to admit an elongate endoscope body into the first lumen, and a transparent tip located longitudinally adjacent to an endoscope lens when the elongate endoscope body is located within the first lumen. The endoscope sheath may also include an elongate secondary tube defining a secondary lumen. A method of using the medical device sheath is also described.

In some embodiments, an electronic laryngoscope includes a camera, a hollow connecting rod, a handle, and a control display. The front end of the connecting rod is connected to the camera, the rear end of the connecting rod is connected to the handle, and the rear end of the handle is connected to the control display. The laryngoscope further includes a hollow tube whose inner diameter is greater than the outer diameter of the connecting rod. The camera and the connecting rod are located on the inner side of the hollow tube. A sputum suction opening is formed between the front end of the hollow tube and the front end of the camera, and a sputum passage in communication with the opening is formed between the hollow tube and the connecting rod. The laryngoscope further includes a connector between the hollow tube and the camera and/or the connecting rod.

Apparatus and processes for use in a narrow body lumen are provided. Apparatus may include an outer shaft portion; a tube receivable within the outer shaft portion; and an elongate inflatable body having first and second ends, the first end being sealed to the outer shaft portion and the second end being sealed to the tube. In an initial configuration, the elongate inflatable body is received in the outer shaft portion. The tube is slidable relative to the outer shaft portion to evert the elongate inflatable body when the elongate inflatable body moves out of the outer shaft portion.
