NIDHI LITH SEMI DIGI
“NIDHILITH” is a intra corporeal pneumatic stone fragmentation device which fragments the stones in the kidneys, ureters and bladder by direct contact lithotripsy, under the direct vision endoscopic treatment. This versatile, still simple and users friendly device proved to provide a most sophisticated and economical method to achieve the intra corporeal pneumatic lithotripsy. The most striking feature of “NIDHILITH” 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” provides very effective, safe, inexpensive and more reliable system for intra corporeal lithotripsy.
The “NIDHILITH” consists of a Control Unit, Hand Piece and Solid Probes. The foot-switch operated, microprocessor based control unit is a highly precise electro-pneumatic device provided with the standard electrical supply as well as the clean and dry compressed air. It is connected with the hand piece through flexible tubing. The rigid probe is connected to hand piece. The probe tip is placed in direct contact with the stones. As soon as the control unit energizes by the foot switch, the compressed air enters the hand piece and propels a small piston against the base of the probe at a frequency from 1 cycles/sec to 12 cycles/sec. The ballistic energy is then transmitted through the probe into the stone, thereby fragmenting the stone.
The limitation of the “NIDHILITH” is its rigid probe design as it can be used only with rigid and semi-rigid endoscopes.
Function of Urinary System
The urinary system consists of two kidneys, two ureters, bladder and urethra. The kidneys principally function to filter the waste products from the blood and circulate the cleaned blood in the body. The ureters carry the waste products (urine) from the kidneys to the bladder. In the bladder the urine is stored until urination. Thereafter, the urine passes out of the body through urethra.
Formation of the Stone
The hyper concentration of the dissolved chemicals in the urine crystallizes them. Mass of such crystals forms up the stones anywhere in the ureters, kidneys and bladder.
There are different types of stones such as Calcium Oxalate (Monohydrate or Dihydrate), Calcium Phosphate, Uric Acid, Struvite, Cystine and Xanthine etc. The stones may vary in size, number and consistency according to their chemical compositions.

|Hand Piece ( Made from non toxic aluminium Alloy )|
|Size||0.8mm, 1mm, 1.1mm, 1.2mm, 1.4mm, 1.5mm|
Prior to the surgical operation, ensure that the Hand Piece and the Probe are duly sterile. Formalin or Cidex sterilization can be preferred. During sterilization, ‘sterilization / protection cap’ must be placed on the Hand Piece.
Before starting the surgical operation, confirm that the Hand Piece is properly assembled and the system is working. Test the working of the Hand Piece by energizing the control unit by foot-switch for a while. You will receive jolts to your hand ensuring that the system is working. Make sure that the Hand Piece is not in contact with any part of the human body.
Ureteric Stone : Probes of 1mm, 1.2mm, 1.4mm are supplied as standard accessories for the use in Ureteroscopy. Probes of 0.8mm, 1.1mm and 1.5mm can be supplied on specific request. Select the probe which can pass through the scope easily reveling the smooth movement and better endoscopic vision. The bigger probe in diameter will help you in better fragmentation and reducing the procedure time.
Kidney Stone : Probes of 2.5mm and 3.0mm are supplied as standard accessories for use in Per Cutaneous Nephro Lithotripsy.
Bladder Stone : 1.5mm for treating bladder stone with cystoscope sheath as an optional accessory.
The frequency can be obtained in a single pulse as well as multiple pulses.
Single Pulse : The control unit is energized for single pulse on the tip of the probe by pressing the foot-switch. This is ideal for ureteroscopy towards better and controlled fragmentation, thereby avoiding migration of the stone from the ureter.
Multiple Pulse : The control unit is energized for the multiple pulse, varying from 1 impact per second to 12 impacts per second linearly by rotating selector switch; on the tip of the probe, by pressing the foot-switch. This mode is useful for fast fragmentation of hard as well as large calculi. For fast and controlled fragmentation it is advisable to keep the frequency between 5 impacts per second and 8 impacts per second per second.
Ureteric stones : The permitted operating pressure is between 1 kg./cm2 and 2.5 Kg./cm2.
For the fast and controlled fragmentation, the pressure and frequency is to be adjusted according to the hardness of the stone.
After every surgical procedure, dismantle the Hand Piece completely, clean all the parts gently applying the spirit by dry cotton and ensure that no foreign particle enters the cylinder. Do not use harsh detergents to clean. The liquid soap / light detergents can be used for cleaning the Hand Piece and its parts.
