An endoscope including an elongated insertion section; a side observation window that includes a tapered part on a side circumference intersecting in a longitudinal axis direction of the insertion section, a circumferential side surface formed in a cone shape; and a cleaning nozzle that includes an opening through which liquid cleaning the circumferential side surface of the side observation window is ejected. The opening is inclined to direct an ejection direction of the liquid toward a distal end of the tapered part. A center position of the opening part of the cleaning nozzle is provided on a proximal end side with respect to a center position of the side observation window in the longitudinal axis direction.

Endoscope having observation window with circumferential side surface and cleaning nozzles directed to circumferential side surface

A video processor includes: an image processing section including a front image enhancement processing section configured to perform first enhancement processing on a front image acquired from a front area in a subject by using an endoscope including an insertion portion which is inserted into the subject, and a side image enhancement processing section configured to perform second enhancement processing on a side image acquired from a side area located lateral to the front area by using the endoscope; and a control section configured to individually set an enhancement level of enhancement processing performed by the front image enhancement processing section and an enhancement level of enhancement processing performed by the side image enhancement processing section.

Image processing apparatus for endoscope and endoscope system

An endoscope of the invention includes: an insertion portion; a distal end portion; a pair of first observation image acquiring sections; a second observation image acquiring section; a pair of nozzles, each of which includes a spouting port for spouting fluid toward each of the pair of first observation image acquiring sections; a pair of first protruding portions, each of which is located close to the front surface of the distal end portion and has a maximum dimension in the radial direction larger than a dimension in the radial direction of each of the nozzles, and a pair of second protruding portions, each of which is located farther from the front surface of the distal end portion and has a maximum dimension in the radial direction larger than the dimension in the radial direction of each of the nozzles.

Endoscope having image acquisition windows and corresponding cleaning nozzles on front and circumferential surfaces

A bending tube for an endoscope, which is provided inside a bending portion of an insertion portion of an endoscope and includes a plurality of bending pieces covered by a flexible tube body, the bending tube including a distalmost end bending piece connected to a distal end portion of an insertion portion, a proximalmost end bending piece connected to a flexible tube portion of the insertion portion, and a net-like tube covering an outer periphery of the plurality of bending pieces except the distalmost end bending piece and the proximalmost end bending piece and including a distal end part fixed to a first bending piece joined to the distalmost end bending piece and a proximal end part fixed to a second bending piece joined to the proximalmost end bending piece.
