Title:
ULTRASONIC ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2014/010283
Kind Code:
A1
Abstract:
In the present invention, proximal-side wiring boards (40-3, 40-4) are arranged so that wiring layers (42-3, 42-4) are oriented inwardly and face each other and ground layers (43-3, 43-4) are oriented outwardly and oppose an interior-side wall of a nosepiece (16). In turn, distal-side wiring boards (40-1, 40-2) are bent so as to have an L-shaped cross-sectional shape when cut in a direction orthogonal to an insertion axis and are arranged so as to partially overlap at a base side of the nosepiece (16) interior to form a U-shape opening toward an acoustic lens section (15a) side. This obviates the need for the laborious work of separately preparing shielding cases and assembling wiring boards into the nosepiece for each of the shielding cases, and makes it possible to facilitate accommodating the wiring board in the nosepiece and improve the workability of assembly.
