Transesophageal ultrasound probe having a rotating endoscope shaft

Abstract

A transesophageal ultrasound probe for imaging internal structures via an imaging element located on the distal end of a rotating endoscope shaft. The probe includes a rotating endoscope having an imaging element mounted on the distal end of the rotating endoscope shaft. The probe also includes a control handle for controlling the imaging controls and a rotation tube that extends through the rotating endoscope shaft and into the control handle. The rotating shaft rotates relative to, and independently of, the control handle. Preferably, the rotating shaft is rotated via a rotation control wheel. The rotation control wheel is fastened or bonded to the rotating tube so that manual rotation of the control wheel causes the rotation tube to rotate, and therefore, the rotating shaft to rotate. Because the rotating endoscope shaft rotates, an imaging element located on, or within, the rotating shaft also rotates.
