摘要： A mechanically-expandable instrument for treating diseases in the urethra and the neck of the urinary bladder, comprising a driver having two elements which, upon selective activation thereof, will reciprocate in two mutually opposite directions; a probe comprising two rods, each having a semicircular cross-section such that when one of the rods is placed adjacent the other, they will form a substantially complete circle in cross section. The rods are attached to each other at one end thereof to form a tip, their other ends being attached to the respective reciprocating elements, the mating surfaces of the rods having at least one pair of engaging cams, for causing the rods to expand and contract in diameter due to engagement of the cams in response to reciprocations of the rods.
