Abstract: An ultrasonic endoscopic probe is provided with an articulating distal tip (14) at which an ultrasonic transducer (130) is located. The articulating section (30) of the probe can be locked in an articulated position by a lock control (28,28') located at a control section (10) of the probe. The locking force is variably selectable by the user, so that the articulating section (30) will be locked in position by a desired force. The articulating section (30) is controlled by cables (74,76,129), which include cable tension adjustments (70a,70b) that also serve to delimit the range of articulation. The articulating section (30) is formed of alternating pivot rings (120) with intervening polymeric pivot beads (106), which provide repetitively smooth articulation. The ultrasonic transducer (130) is rotatable to steer the acoustic scan plane during use, and a sliding membrane (164) between the transducer (130) and its acoustic window (162) allows the transducer (130) to rotate smoothly without sticking.

Abstract translation: 超声波内窥镜探针设置有超声波换能器（130）所位于的关节式远侧末端（14）。 探针的铰接部分（30）可以通过位于探针的控制部分（10）处的锁定控制器（28,28'）锁定在铰接位置。 锁定力由使用者可变地选择，使得铰接部分（30）将通过期望的力锁定就位。 铰接部段（30）由缆索（74,76,129）控制，缆索（74,76,129）包括也用于界定铰接范围的缆索张力调节器（70a，70b）。 铰接部段（30）由交替的枢轴环（120）形成，中间的聚合物枢转凸起（106）提供重复平滑的铰接。 超声波换能器130可旋转以在使用期间操纵声学扫描平面，并且换能器130与其声学窗口162之间的滑动膜164允许换能器130平稳地旋转而不会粘连。
