A recently granted patent (Publication Number: US11864721B2) discloses an innovative endoscopic end cap designed to enhance the field of view during endoscopic procedures. The end cap comprises a sleeve member, a projecting element, and a movable sleeve. When the endoscope is withdrawn, the movable sleeve moves towards the distal end of the endoscopic shaft, providing support for the projecting element, which dilates to enlarge the field of view. The projecting element consists of umbrella-shaped elements and connecting rods, allowing for controlled movement and positioning during insertion and withdrawal of the endoscope.

Furthermore, the endoscopic end cap forms a smooth cylindrical structure when inserted, thanks to the coordinated movement of the movable sleeve and projecting element. The end cap is made from materials like silicone, rubber, or plastic, with the projecting element potentially woven from a nickel-titanium memory alloy wire. Additional features include an end cap cover for protection and a variety of shapes for the sleeve member, such as circle, ellipse, triangle, cone, or polygon. These design elements aim to improve the functionality and versatility of endoscopic procedures, offering healthcare professionals a more efficient and effective tool for diagnostic and therapeutic interventions.
