There is provided an endoscope that allows treatment, which uses treatment tools, to be performed accurately. An observation window is disposed across a vertical axis in a distal end surface region positioned above a horizontal axis; a first treatment tool outlet port is disposed across the vertical axis in a distal end surface region positioned below the horizontal axis; a second treatment tool outlet port is disposed across the horizontal axis in a distal end surface region positioned below a line, which passes through a center of the observation window and is parallel to the horizontal axis, and in a distal end surface region positioned on a left side of the vertical axis; and a front water supply port is mainly disposed in the distal end surface region positioned below the line, which passes through the center of the observation window and is parallel to the horizontal axis, and in a distal end surface region positioned on a side opposite to the second treatment tool outlet port with respect to a line that passes through a center of the first treatment tool outlet port and is parallel to the vertical axis.

Endoscope distal end for treatment tools, observation and fluid supply

An observation window is mainly disposed in a distal end surface region positioned above a horizontal axis, a first treatment tool outlet port is mainly disposed in a distal end surface region positioned below the horizontal axis, and a position of a center of a front water supply port in a direction of a vertical axis is disposed between a position of a center of the observation window and a position of a center of the first treatment tool outlet port in the direction of the vertical axis.

Endoscope having a treatment tool outlet port

There is provided an endoscope that allows treatment, which uses treatment tools, to be performed accurately. An observation window is mainly disposed in a nearby region, a first treatment tool outlet port is mainly disposed in a fourth quadrant, a second treatment tool outlet port is mainly disposed in a third quadrant, and an upper end position of the second treatment tool outlet port is disposed above an upper end position of the first treatment tool outlet port.
