"NIDHILITH Digi" is a unique device for intra corporeal stone fragmentation by "Direct Contact Lithotripsy" under direct vision endoscopic control. "NIDHILITH Digi" is the intra corporeal Pneumatic lithotripter having supremacy in techno-applicabitiy point of view. It is a most reliable device, found to be an inexpensive and safe form of lithotripsy for fragmenting stones in the kidney, ureter and urinary bladder. We have a model "NIDHILITH Digi" that is a quite sophisticated digitally controlled pressure flow device. It generates highly accurate pulses by means of digitally controlled microprocessor based device in single pulse as well as continuous pulse mode. In continuous pulse mode it facilitates to indicate number of pulses per second via digital display that can be adjustable by feather touch switch. The most striking feature of "NIDHILITH Digi" is the design of its rigid probe, which results in rapid and safe fragmentation of the large and hard calculi situated anywhere in the urinary system i.e. kidneys, ureters and bladder. Therefore, there is no chance of any heat generation on the tip of the probe and consequent damage to the mucosa. Being based on the simple operating principle, the "NIDHILITH Digi" provides very effective, safe, inexpensive and more reliable system for intra corporeal lithotripsy.
