Abstract: An ultrasound endoscope, having a cable for connecting the ultrasound endoscope to a driving apparatus, includes an insertion section insertable into a subject, a plurality of transducers provided at a distal end portion, an electrode formed in each of the transducers, a wiring section connected to the electrode to electrically connect the electrode and the cable, and matching circuits, at least one of which is provided at an end of or partway in each of the wiring section. The electrode, the wiring section, and the matching circuits are provided in each of the plurality of transducers. The cable includes a core wire and an insulating layer enwrapping the core wire and functions as a matching section that matches electric impedance of each of the transducers between the plurality of transducers and the driving apparatus by varying a thickness or quality of material of the insulating layer.

Abstract: A puncture treatment instrument for endoscope of the present invention includes: a concave portion with an opening on a distal end side and a bottom surface on a proximal end side; a holding portion adjacent to a proximal end of the concave portion, the holding portion allowing advancement and retraction of a needle; a puncture needle with a full length longer than a distance from a proximal end of the holding portion to a distal end of the concave portion; and a locking portion that generates resistance force in an advancing direction to stop retraction of the puncture needle when the puncture needle is retracted after the puncture needle is advanced to project into the concave portion from the holding portion.

Abstract translation: 本发明的内窥镜用穿刺处理器具具有：前端侧开口部和基端侧底面的凹部， 与所述凹部的近端相邻的保持部，所述保持部允许针的前进和后退; 穿刺针，其全长比从所述保持部的近端到所述凹部的前端的距离长; 以及锁定部，其在穿刺针前进后从所述保持部突出到所述凹部中时，在所述推进方向上产生阻力，从而停止所述穿刺针在所述穿刺针退避时的收缩。
