Abstract

A combined ultrasonic and endoscopy system (100) includes a cannula (240) with a distal tip (250) configured for insertion into an internal organ or other internal body structure. The distal tip (250) is configured to include both an ultrasound probe head (252) and a camera module (320). The ultrasonic and direct vision endoscopy images (154, 156) can be simultaneously displayed to a user on a display monitor (150, 152). The ultrasound probe head (252) can be rotated and steered to scan any location in the human organ cavity. The ultrasound probe (410) can be re-usable or single use. The system (100) can be configured with a handheld portion (110) that includes a re-usable handle portion (130) and a single use portion (120) that is configured to be disposed of following a single use. The system (100) can also be configured using a conventional re-usable endoscope with working channels (920, 1020) and an endoscopy processing tower system (112, 116, 118).
