no. 1 Embodiment approach

[0043] The adhesive composition and endoscope device according to the first embodiment of the present invention will be described below.

[0044] The inventors of the present invention conducted intensive studies to further improve the sterilization resistance of an adhesive layer obtained by curing an adhesive composition in a sterilization process using a sterile gas. The present inventors newly discovered that the sterilization resistance of the adhesive layer can be remarkably improved by adding an inorganic double ion exchanger, which has never been used in adhesives for medical devices, to the adhesive composition, thereby completing the present invention. invention.

[0045] The adhesive composition of this embodiment contains an epoxy resin and an inorganic double ion exchanger. Here, the inorganic double ion exchanger refers to an inorganic compound having a property of exchanging surrounding anions and cations with its own ions.

[0046] The adhesive composition of...

no. 2 Embodiment approach

[0134] Next, an adhesive composition, an ultrasonic vibrator, and an ultrasonic endoscope device according to a second embodiment of the present invention will be described.

[0135] An ultrasonic endoscope device is known as one type of endoscope device. The ultrasonic endoscope apparatus has an ultrasonic transducer on which an acoustic matching layer is formed in order to enable observation of the submucosal interior.

[0136] The acoustic matching layer in the ultrasonic transducer is required to have appropriate acoustic characteristics according to the acoustic characteristics of the object to be observed. As the base material of the acoustic matching layer, epoxy-based resins, urethane-based resins, and the like are often used.

[0137] For example, Japanese Patent Application Laid-Open No. 2014-188009 describes an ultrasonic probe used for ultrasonic image diagnosis. The ultrasonic probe has an acoustic matching layer, which is made by adding zinc white, titanium oxi...

no. 3 Embodiment approach

[0196] Next, an ultrasonic vibrator according to a third embodiment of the present invention will be described.

[0197] Figure 6 It is a schematic cross-sectional view showing a schematic configuration of an ultrasonic vibrator according to a third embodiment of the present invention.

[0198] Such as Figure 6 As shown, the ultrasonic vibrator 110A of this embodiment includes a piezoelectric element 121, a backing material 122, an acoustic matching layer 123 (resin cured layer), and an acoustic lens 124 instead of the piezoelectric element 111 of the ultrasonic vibrator 110 of the second embodiment. , backing material 112, acoustic matching layer 113 and acoustic lens 114.

[0199] The following description will focus on differences from the second embodiment described above.

[0200] The piezoelectric element 121 is disc-shaped. Electrodes (not shown) for applying a voltage to the piezoelectric element 121 are provided on the surfaces 121 a and 121 b on both sides of t...

Abstract

This adhesive composition contains an epoxy resin as a main component, and includes an inorganic zwitterion exchanger.

Description

technical field [0001] The present invention relates to an adhesive composition, an ultrasonic vibrator, an endoscope device, and an ultrasonic endoscope device. [0002] This application claims priority based on Japanese Patent Application No. 2016-106558 filed in Japan on May 27, 2016 and Japanese Patent Application No. 2016-221826 filed in Japan on November 14, 2016, the contents of which are incorporated herein by reference. Background technique [0003] In recent years, low-invasive medicine that reduces the burden on patients has attracted attention. For example, a treatment method using an endoscope device is known as one type of low-invasive medical treatment. [0004] In an endoscope device, in order to ensure the liquid-tightness of the insertion part, for example, a tie wire is used to fix the side surface of the cap at the distal end and the sheath tube covering the side surface of the insertion part. For example, the tie wire is wound around the surface of the...
