ULTRASONIC SCANNER FOR EXAMINATION OF A COELIAC CAVITY

摘要

With an ultrasonic scanner for coeliac examination, the distal end of the insertion section is provided with a distal end part consisting of a beam-scanning section and beam transmitting and receiving section. The beam-scanning section comprises a beam mirror set in a beam-scanning chamber formed in a casing. A reflection plane formed at one end of the beam mirror is inclined at an angle of, for example, 45 DEG to its rotation axis. The beam mirror is rotated by means of a mirror shaft and flexible shaft. The beam transmitting and receiving section comprises a holder in which a vibrator is set. The holder is securely fitted into a receptacle formed in the casing by the threaded engagement of a fitting cap with the receptacle. The vibrator is electrically connected to the insertion body in a detachable state.
