Details of Clinical Evaluation: In this application, a 7.5F scope was used with a 10F sheath. From the actual usage experience, the 7.5F scope offered good handling, facilitating stable manipulation by the operator. Meanwhile, the imaging clarity of the scope met the clinical operation requirements, providing the operator with a clear field of view for observing lesions and performing precise operations. In addition, the hydrophilic coating on the surface of the 10F sheath played a key role during the insertion process: it effectively reduced insertion resistance, making the sheath insertion smooth and easy, and lowering the operation difficulty. Overall, the performance of the two products in use met clinical expectations and was recognized by the operator (Director Li) and relevant users.
