ABSTRACT:
A dilator for surgical use having a ball on the end of a thin stiff stem. A plurality of telescoping tubes are adapted to be slid along the stem and atop one another so as successively to enlarge the path opened by the dilator. An endoscope shaft can be slid over the set of tubes so as to occupy the region they have enlarged, and to permit them and the probe to be withdrawn so an endoscopic procedure can be performed.
