Combined endoscope and ultrasonic diagnostic device

Abstract

Abstract A combined endoscope and ultrasonic diagnostic device for the examination of a body cavity interior, an ultrasonic probe tip (23) being mounted to be inserted directly into a body cavity and transmit and receive ultrasonic waves to diagnose an internal organ or the like within the body cavity with the aid of an endoscope (27) contained in a housing forming an insertion sheath (21) and inserted into the body cavity to observe the body cavity interior. In this kind of diagnostic device, the field of view of the endoscope may be adversely intercepted by the probe tip, and/or the position in which the probe tip is to contact an internal organ can not be viewed if the probe tip can not be sighted via the endoscope, so that with known devices it is difficult to bring the probe tip into close contact with the internal organ in a predetermined position, and to check the position of contact with the internal organ. The proposed device has a probe tip (23) with a window (22/ for transmitting and receiving ultrasonic waves, mounted on a bendable part (24) provided on the front of a long insertion sheath (21) and the endoscope (27) is positioned to view through an incised window (25) in the outer periphery of the insertion sheath (21) to the rear of the bendable part (24) so that the probe tip (23) may be viewed via the endoscope (27) when the bendable part (24) is operated.
