To achieve an accurate bending operation in a specific direction on a joystick-type bending lever, an endoscope includes: a bending operation mechanism including a bending lever configured to be tilted in all directions including a first direction, a second direction, a third direction, and a fourth direction corresponding to bending directions in up, down, left, and right directions, respectively, of a bending portion; a long hole provided in the bending operation mechanism; and an engagement pin provided on an operation portion and configured to engage with the long hole. The engagement pin is guided into the long hole and the bending operation mechanism is supported such that the bending operation mechanism is movable relative to the operation portion.

Endoscope

Connector for endoscope

An endoscope includes: a coil spring which is helically wound around an outer periphery of a treatment instrument channel disposed in an insertion section, the coil spring including a distal end which is fixed to the insertion section on a distal end portion side with respect to a bending portion; and a slide member disposed on a proximal end side of the coil spring, the slide member provided for applying an operation force for deforming the coil spring so as to increase a bending strength of at least a portion of the coil spring corresponding to the inside of the bending portion.

An endoscope includes an insertion portion, a distal end rigid member, and a channel tube. The distal end rigid member is provided on a distal end side with respect to the bending portion of the insertion portion, and includes an illumination window, an observation window, and a treatment instrument opening. As the distal end rigid member moves relative to the bending portion in a distal end direction of a longitudinal axial direction, the distal end rigid member can change from a first state in which a distance between a proximal end surface of the distal end rigid member and a distal end surface of the bending portion is fixed to a first distance to a second state in which the distance is equal to a second distance longer than the first distance.

An endoscope capable of being autoclaved in accordance with the present invention includes an insertion unit, an internal endoscope space, and contents. The insertion unit has a soft member, which is made of a soft polymeric material, as at least part of a casing thereof. The internal endoscope space includes the internal space of the insertion unit that is formed at a first sealing level at which the internal space is sealed in a watertight manner relative to an outside. The contents include at least one hermetically sealed unit composed of a plurality of airtight partition members and formed at a second sealing level higher than the first sealing level by joining the meeting portions of the airtight partition members using an airtight joining material. All or part of the airtight partition members is stowed in the internal endoscope space. Even when high-pressure high-temperature steam permeates through the soft member of the insertion unit which is made of a polymeric material, and invades into the internal endoscope space formed at the first sealing level, the high-pressure high-temperature steam will be hindered from invading into the hermetically sealed unit included in the contents and formed at the second sealing level.

Endoscope capable of being autoclaved

An endoscope suitable for autoclave sterilization includes an insertion section having an objective lens section disposed at the extreme end thereof for focusing a subject image and an eyepiece section located on the base end side of the inserting section and including at least an eyepiece lens. an image guide fiber is disposed in the bundle for transmitting the subject image in an observation section focused by the objective lens section. An eyepiece lens unit is disposed in the eyepiece section, the eyepiece lens unit causing the eyepiece lens to confront the base end structure whose hermetic seal level is higher than the watertight seal level of the shell of the endoscope. A focus position changing means is disposed to the eyepiece lens unit to change the focus position of the eyepiece lens. The eyepiece section is so constructed and/or assembled that the autoclave sterilization process does not cause water vapor or the like to adversely affect the operability of the eyepiece section.

Endoscope suitable for autoclave sterilization

An endoscope includes an image pickup unit having a solid-state image pickup device such as a CCD on a tip end side of an elongate insertion section. This image pickup unit constitutes a tip end side unit U and a rear end side unit U by conducting a surface treatment (metallization) to nonmetal members such as a tip end cover glass and a rear end cover glass and by airtight coupling surface-treated portions of the nonmetal members to metal members such as a tip end cover glass frame and a rear end cover glass frame by brazing using soldering, and constitutes an optical system unit by airtight coupling the metal members to metal members of an insulating unit U formed by airtight coupling a pipe member and a ring member to an insulating frame by welding.

Endoscope apparatus

An electronic endoscope system comprises an insertional part at least part of whose armor is a conductor, an imaging unit incorporated in the insertional part and realized with a solid-state imaging device, a signal transmitting device for transmitting an electric signal that results from photoelectric conversion performed by the solid-state imaging device, and a signal processor for transforming an electric signal transmitted by the signal transmitting device into a video signal. The conductor serving as the armor of the insertional part is electrically isolated from the imaging unit, signal transmitting device, signal processor, and around.

A cover-system endoscope comprises the main body of an endoscope and an endoscope cover assembly for covering the main body of the endoscope. The endoscope cover assembly includes a direction changing means such as a tube body, an erecting base having a hinge section or a balloon for erecting the erecting base in order to change the direction of a medical treatment instrument which is inserted through the medical treatment instrument channel.

Endoscope cover assembly and cover-system endoscope

A heat using therapeutic device includes an applicator provided with an insertion section, a balloon enclosing a high frequency warming electrode attached to the insertion section of the applicator; medicine ejecting holes arranged on the balloon; and a medicine passage for connecting the medicine ejecting holes to a medicine mouth piece attached to a rear end of the applicator.
