ABSTRACT:
A urological instrument for use with an endoscope and an endoscope sheath to facilitate the insertion of one or more catheters or flexible instruments from the bladder into the ureter. The instrument includes an elongated sleeve for receiving the stem of the endoscope, a deflecting element pivotally mounted at the distal end of that sleeve, and a mechanism at the proximal end of the sleeve for operating the deflecting element. The mechanism is spring-loaded so that the deflecting element normally assumes a retracted position generally parallel with the axis of the sleeve. Such mechanism also includes a finger lever for selectively controlling the angular position of the deflecting element. A finger brace projects outwardly from the sleeve on the opposite side from the lever. The construction allows a urologist to operate the mechanism with the same hand used to support the instrument, thereby freeing his other hand for manipulation of the catheter or flexible instrument to be deflected by the pivotal deflecting element.
