Problems solved by technology

Therefore, in optical observation, there may be a problem that a part of the observation field of view is blocked by the ultrasonic signal transmitting and receiving unit, or that a shadow of the ultrasonic vibrator unit is generated during optical imaging, which hinders observation.
In addition, in ultrasonic observation, there may be a problem that an artifact may appear in the ultrasonic image due to the reflection of ultrasonic waves by the air and water nozzles, etc.

Abstract

An ultrasound endoscope including, at a distal end of an insertion portion to be inserted to a body cavity, a distal rigid portion arranged forward of a flexible tube portion, an ultrasound transducer portion for scanning a plane which is parallel to forward side of a longitudinal center axis L1 of the distal rigid portion, and a treatment instrument insertion channel port opening in a distal-side end face of the distal rigid portion, with a longitudinal center axis L4 being parallel to the longitudinal center axis L1 of the distal rigid portion.

Description

technical field [0001] The present invention relates to an ultrasonic endoscope having an observation optical system, a treatment tool outlet, and a convex ultrasonic signal transmitting and receiving unit at the front end of an insertion unit. Background technique [0002] Conventionally, an ultrasonic endoscope having a convex ultrasonic signal transmitting and receiving unit is known as an ultrasonic endoscope for performing ultrasonic diagnosis in a body cavity. The convex ultrasonic signal transmitting and receiving part is formed by arranging a plurality of transducer arrays in a convex arc shape. [0003] As an ultrasonic endoscope having a convex ultrasonic signal transmitting and receiving unit, there is, for example, an ultrasonic endoscope disclosed in Japanese Patent Application Laid-Open No. 8-131442. The distal end hard part of this ultrasonic endoscope has an observation optical system, and also has an ultrasonic signal transmitting and receiving part with an...
