Embodiment Construction

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, if figure 1 As shown, the ultrasonic endoscope is roughly composed of a main body operation part 1 , an insertion part 2 and a universal guide wire 3 . Furthermore, in this ultrasonic endoscope, a light source device, a video signal processing device, and an ultrasonic observation device are connected to constitute a system as a whole. Furthermore, the universal lead wire 3 is led out from the main body operation part 1, branches in the middle, and includes a connector 3a detachably connected to the light source device and a connector 3b detachably connected to the video signal processing device. , and a connector 3c connected to the ultrasonic observation device in a detachable manner.

[0041] The main body operating part 1 can be held by the surgeon with one hand, and is provided with a corner operating part 4 and a treatment instrument introduction ...

Abstract

The invention provides an ultrasonic endoscope which is provided with an endoscope observation component on a rigid part at the top of an insert part. The endoscope observation component is at least provided with an illuminating part and an observation part at the top and is provided with an electronic scanning ultrasonic observation component at the periphery of a mounting part. the ultrasonic endoscope is characterized in that in the ultrasonic observation component configuration, a plurality of ultrasonic vibrators are arranged in a cylinder-shaped or an arc-shaped ultrasonic vibrator array and a cylinder-shaped cushion is formed at the inner side; a plurality of terminals at one side connected with poles of the ultrasonic vibrators, terminals at the other side connected with cables respectively and a flexible substrates forming a wiring pattern between the terminals at one side and the terminals at the other side are arranged between the ultrasonic vibrators array and the cushion; the flexible substrate has a step-shaped structure which forms a big diameter part of the terminals at one side at the exterior side and a small diameter part of the terminals at the other side at the exterior side, and the inner side of the small diameter part is provided with a ring-shaped supporting part.

Description

technical field [0001] The present invention relates to an ultrasonic endoscope, which is provided on the top hard part of the insertion part with an endoscopic observation part having an observation field in front of the top hard part, and having a An electronic scanning ultrasonic observation component with intersecting circumferential or arc-shaped ultrasonic scanning surfaces. Background technique [0002] Ultrasonic endoscopes are equipped with an endoscope observation unit for observing the interior of the body cavity at the tip hard part of the insertion part, an endoscope mechanism including other parts such as a treatment instrument insertion part for inserting forceps and other treatment instruments, and an ultrasonic endoscope. A so-called electronic scanning type device in which a plurality of ultrasonic transducers are arranged in a predetermined direction and these ultrasonic transducers are sequentially driven has been widely used as a scanning form by the ult...
