Problems solved by technology

Therefore, when the size of each part constituting these ultrasonic observation components and endoscope observation components is set to a necessary size under the premise of ensuring their respective functions, the outer diameter of the top hard part becomes larger, so that not only The insertion operability deteriorates, and the burden on the patient increases
On the other hand, if you want to reduce the outer diameter of the top hard part, it is necessary to miniaturize any one or more components that constitute the ultrasonic observation part or endoscope observation part, which may produce functional upper limit

Embodiment Construction

[0048] 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, and is branched in the middle, thereby comprising a connector 3a detachably connected to the light source device and a connector detachably connected to the video signal processing device. 3b, and a connector 3c detachably connected to the ultrasonic observation device.

[0049] 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 introductio...

Abstract

An ultrasonic endoscope comprises an insertion portion comprising a distal hard portion which has: an endoscopic observation unit; and an ultrasonic observation unit having ultrasonic transducers arranged circumferentially on an outer circumferential section of the distal hard portion, wherein the ultrasonic observation unit comprises an ultrasonic-wave transmission / reception unit having an tunnel-shaped path which has an inner circumferential surface formed as a backing layer; a distal block is arranged on a distal side in an axial direction of the distal hard portion with respect to a location where the ultrasonic-wave transmission / reception unit is arranged, and distal ends of respective members constituting the endoscopic observation unit are fixed to the distal block; and part of the members which constitute the endoscopic observation unit are fitted so as to be partially protruded from an inside diameter of the tunnel-shaped path toward an outer circumferential side thereof.

Description

technical field [0001] The present invention relates to an ultrasonic endoscope, which is an endoscopic observation part having an observation field of view provided in front of the front end hard part of the insertion part, and having a Ultrasonic endoscopes with electronic scanning ultrasonic observation components with circumferential or arc-shaped ultrasonic scanning surfaces. Background technique [0002] Ultrasonic endoscopes are equipped with an endoscope observation unit for observing the inside 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 ultra...
