US 12,564,375 B2 · Devices, systems, and methods for securely and selectively attaching an ultrasound accessory to an endoscope

Abstract

A sleeve configured to be dispositioned between an endoscope and an ultrasound accessory selectively attachable to the endoscope is disclosed herein. The sleeve can include a rigid body configured to maintain a structural integrity of the sleeve, a first flexible layer positioned about an inner surface of the rigid body, and a second flexible layer positioned about an outer surface of the rigid body. The first flexible layer can create a friction fit between the inner surface of the rigid body and an outer surface of the endoscope and the second flexible layer can create a friction fit between the outer surface of the rigid body and the ultrasound accessory. The sleeve can be inserted into an inner bushing that includes a connecting plate configured for alignment with a positioning plate of the ultrasound accessory such that the ultrasound accessory is properly positioned when selectively attached to the endoscope.
