Description: 12.25“x 1.75“x 2” black box contains 11.5” nickle plated instrument with slight curve at end. Turning a screw at opposite end separates two pieces and the degree of separation is recorded on a circular dial near the screw. There is a loop for the finger at this end. Two knives, which can be inserted into the urethra to partially open the stricture to make room for the instrument are also included. One knife is ratcheted and can be advanced by rack and pinion. Another approach to a common 19th century problem of urethral stricture. These devices are still in use.
