Oblique-viewing curved linear-array echoendoscopes are widely used for interventional endoscopic ultrasound (EUS), not only for diagnostic but also for therapeutic procedures. Recently, development of a forward-viewing curved linear-array echoendoscope (FV-ES) has been made. Several reports describe the usefulness of this new equipment for therapeutic interventional EUS, especially for pseudocyst drainage. A salient advantage of the FV-ES is that it enables the axial application of force during needle insertion and stenting. Furthermore, by attaching a cap device to the tip, the endoscope's capability can be expanded. Although the FV-ES has a narrower scanning range (90 deg) than that afforded by the oblique-viewing curved linear-array echoendoscope (180 deg), this characteristic reportedly does not hinder the performance of interventional EUS. The FV-ES might contribute to the advancement of interventional EUS.
斜视角弯曲线阵超声内镜广泛应用于介入性内镜超声（EUS），不仅用于诊断，也用于治疗程序。最近，已经开发出一种前视弯曲线阵超声内镜（FV-ES）。有几份报告描述了这种新设备在治疗性介入性 EUS 中的有用性，特别是用于假性囊肿引流。FV-ES 的一个显著优点是它能够在针插入和支架置入过程中轴向施力。此外，通过在尖端附加一个帽装置，可以扩展内镜的功能。尽管 FV-ES 的扫描范围（90 度）比斜视角弯曲线阵超声内镜（180 度）窄，但据报道，这一特征并不妨碍介入性 EUS 的性能。FV-ES 可能有助于介入性 EUS 的发展。
