Ultrasonic attachment assembly for an endoscope

An ultrasonic attachment assembly, comprising:

• an ultrasonic transducer comprising:
• a transducer lens comprising a field of view;
• and
• a transducer body:
• a clip configured to be removably secured to a distal end of a duodenoscope comprising an elevator channel, wherein the distal end of the duodenoscope defines a central axis, wherein the elevator channel defines an elevator channel axis that is offset from the central axis, and wherein the clip comprises:
• a clip body;
• and
• a cavity formed in the clip body, wherein the cavity is configured to hold the transducer body when the clip is secured to the distal end of the duodenoscope such that the transducer lens is positioned distally with respect to the distal end of the duodenoscope and such that the field of view is centered along the elevator channel axis;
• and
• a sleeve configured to slide around the distal end of the duodenoscope, wherein the sleeve comprises a tab extending radially therefrom, wherein the clip is configured to be placed over the sleeve to position the clip on the distal end of the duodenoscope, and wherein the clip further comprises an opening formed in the clip body, the opening configured for the tab to extend therethrough when the clip is placed over the sleeve to axially and rotationally position the clip with respect to the sleeve.

An ultrasonic attachment assembly, comprising:

• an ultrasonic transducer comprising:
• a transducer lens comprising a field of view;
• and
• a transducer body;
• and
• a sleeve configured to be positioned on a distal end of a duodenoscope by removably sliding the sleeve over the distal end of the duodenoscope, wherein the duodenoscope comprises an elevator channel, wherein the distal end of the duodenoscope defines a central axis, wherein the elevator channel defines an elevator channel axis that is offset from the central axis, wherein the sleeve is configured to selectively engage the transducer body when the sleeve is positioned on the distal end of the duodenoscope such that the transducer lens is positioned distally with respect to the distal end of the duodenoscope and such that that the field of view is centered along the elevator channel axis.
