Abstract: A probe assembly for endoscopic procedures includes a gear motor having a rotatable gear shaft through which a such as a wire or hollow needle is inserted with the probe being clamped to rotate by the gear motor. The probe extends through a catheter and the catheter and probe extend through a medical scope to the location to be viewed by the scope, such as a bile duct. Where the probe is a hollow needle, a stylet may extend outwardly of the needle and jointly rotate with the needle.

Abstract: A probe vibrating assembly for endoscopic procedures includes a base unit having a rotatable spindle. A drive member is eccentrically mounted to the spindle. The drive unit is secured to a slide plate to move the slide plate back and forth while the spindle is rotating. A clamp mechanism is secured to the slide plate and is used for clamping a probe so that the probe also moves back and forth. The probe is mounted to a medical scope.
