摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic endoscope system and an ultrasonic vibrator array in which load on a connection part for connecting an acoustic lens to an endoscope structure member is reduced in attaching/detaching a balloon.;SOLUTION: A balloon lock member 3 and a scope connection member 4 which are the endoscope structure members have respective connection parts to be connected to the acoustic lens 2, and the connection parts have respective outer diameters which are larger than those of the respective connection parts of the acoustic lens 2 to be connected to the balloon lock member 3 and the scop connection member 4. The acoustic lens 2 is connected to the balloon lock member 3 via a connection band 5 which smoothens a step between the acoustic lens 2 and the balloon lock member 3. The acoustic lens 2 is also connected to the scope connection member 4 via a connection band 6 which smoothens a step between the acoustic lens 2 and the scope connection member 4.;COPYRIGHT: (C)2006,JPO&NCIPI
