Abstract

An ultrasonic endoscope device for scanning a patient's organ is constructed using a mobile ultrasonic transducer probe on a carriage housed in a distal and section of the device, within a guide channel formed by a plurality of axially aligned rigid guide links having hollow spaces opened to one side and pivotable by means of a tension wire running through the links. A flexible hose in conjunction with a balloon envelope surround the end section and serves as a water supply path. The device is especially useful for transeophaged echocardiographic scanning.
