Problems solved by technology

Therefore, the operation time becomes longer, and there is a problem that not only the burden on the patient is increased, but also the operation is very complicated for the operator.
[0010] In addition, in the hospital, in order to perform endoscopic retrograde cholangiopancreatography (ERCP) and ultrasonography-guided puncture (FNA), two endoscopic devices must be prepared. The increase in the number of devices will also increase the corresponding costs, as well as the number of flushing and disinfection, etc., resulting in increased funds and complicated sanitation management.

Abstract

An endoscope apparatus 2 according to the present invention includes an insertion portion 9 having a distal end portion 6 and at least two channels 54 and 63; an optical observation system 51 provided on one surface of the distal end portion so as to face an axial direction different from a direction of an insertion axis X of the insertion portion; a first channel opening 41a provided on one surface of the distal end portion near the optical observation system; an ultrasound transducer array 61 provided on the one surface of the distal end portion and having a scanning surface Z parallel to the insertion axis; and a second channel opening 41b provided on a proximal end side of the ultrasound transducer array.

Description

technical field [0001] The present invention relates to an endoscope device capable of performing ultrasonic endoscope-guided puncture and endoscopic retrograde cholangiopancreatography in a single body. Background technique [0002] As is well known, endoscope apparatuses are widely used for observation, treatment, and the like inside a living body (inside a body cavity), and for inspection, repair, and the like in industrial plants. In recent years, as a medical endoscope device, a device capable of performing ultrasonic endoscope-guided paracentesis (FNA) or endoscopic retrograde cholangiopancreatography (ERCP) has been disclosed; Underneath puncture (FNA) conducts pathological examination in order to confirm the surrounding pancreas based on ultrasound images, punctures the cells of the pancreas to sample; the above-mentioned endoscopic retrograde cholangiopancreatography (ERCP) inserts in the pancreatic duct or bile duct Thin tubes are injected with a contrast agent an...
