Urinary tract surgical knives designed to cut the anatomical structures of the lower urinary tract (i.e., bladder and urethra) during endoscopic procedures. These knives typically consist of manual handheld instruments with a handle and a long shaft finished in a cutting end (e.g., straight, half-moon-shaped) at the distal end. These knives are usually intended for use through the working channels of urinary tract resectoscopes, urinary tract endoscopes, and/or cystoscopes. Endoscopic urinary bladder/urethra surgery knives are used in a variety of endoscopic minimal access surgical procedures performed in the lower urinary tract (e.g., treatment of strictures, resection of tumors).
