shock pulse lithotripter

Olympus released the new generation Cyberwand lithotripter, the ShockPulse-SE, a dual-action system for breaking up kidney, ureteral, and bladder stones. According to the company, this is the first

Go to: Shock-wave lithotripsy (SWL) is done with a machine that can break kidney stones from outside the body. To break the stone, focused shock waves (short pulses of high energy sound waves) are transmitted to the stone through the skin. The stone absorbs the energy of the shock waves and breaks into smaller pieces.

The lithotripter attempts to break up the stone with minimal collateral damage by using an externally-applied, focused, high-intensity acoustic pulse. The sedated or anesthetized patient lies down in the apparatus' bed, with the back supported by a water-filled coupling device. An imaging system is used to locate the stone and aim the treatment.

Extracorporeal shock wave lithotripsy therapy treatment uses vary from the most widely known and commonly performed kidney stone treatment to other less common uses like heel spurs, tennis elbow, and even gallstones. The original first generation lithotripter designs had the patient submerged in a bath of water enabling hydrodynamic waves

without tissue present, and exhibited a sharp shock front and similar pulse duration but with reduced amplitude (Fig. 2). Pulse amplitude was attenuated by passage through tissue. With the FOPH at the focal point of the lithotripter, measures with specimens of different thickness showed an increase in

ShockPulse-SE Integrating ultrasound and mechanical energies simultaneously from a single probe enables rapid fragmentation of all types of stones. Percutaneous nephrolithotomy (PCNL/PNL) using a lithotripter has become standard procedure in stone management. Assembling Step 1: Screw probe onto the transducer until loosely connected.

The lithotripter was operated at power level 3 (peak positive pressure 52±2 MPa with output of ∼48-56 MPa from level 1 to 6), fired at a rate of 60 SW/min. Sets of 25 waveforms (8 ns sampling rate, 5000 data points per SW, shock to shock variation <±4%) were stored using a Tektronix digital oscilloscope (TDS 5034; Tektronix, Beaverton, OR) for post-processing. 19 For mapping of the

Time to remove the targeted stone burden is measured at time the lithotripter unit starts fragmenting the stone to time all fragments are removed from the kidney based on visual inspection. This is prior to final visual inspection of the kidney with a flexible nephroscope. Prior shock wave lithotripsy within 3 months of study procedure

Main Principe of Internal Shock Wave Lithotripter. Under direct visual control of endoscope, our lithotripterelectrical pulse with energy lower than 1 J explosion inelectrolyte, the shock wave it formed shatters calculi, ensures enough energy for lithotripsy meanwhile avoids causing damage to tissues, These measures obviously solved the puzzle

The most common use of extracorporeal shockwave therapy (ESWT) is for lithotripsy to treat kidney stones (urinary calculosis) and biliary calculi (stones in the gallbladder or in the liver) using an acoustic pulse.It is also reported to be used for salivary stones and pancreatic stones.. In the UK, the National Institute for Health and Care Excellence (NICE) found that the evidence for

Localizing cavitation to the kidney stone in extracorporeal shock wave lithotripsy may be desirable since cavitation appears to play a major role in both stone comminution and renal tissue damage. Use of a dual-pulse lithotripter to generate a localized and intensified cavitation field J Acoust Soc Am. 2001 Sep;110(3 Pt 1):1685-95. doi: 10.

Conclusions: Passage through the body wall has minimal effect on the characteristics of lithotripter SWs. Other than reducing pulse amplitude and having the potential to affect the symmetry of the focused wave, the body wall has little influence on the acoustic field.

Interstitial water in the porous phantom can also help enhance calculus ablation through microexplosion process. The test result also indicates that the shock waves generated by short laser pulse under the in-water condition have great impact of the ablation volume by Tm:YAG QS laser lithotripter.

1. Introduction. It has been shown that cavitation bubbles produced by a lithotripter shock pulse can play a role in stone breakage and tissue damage (reviewed in []).Recent publications suggest that cavitation can also affect the propagation of the acoustic pulse in vitro [2,3] and in vivo [].Experiments in [] demonstrated that waveforms recorded in the focus of a piezoelectric transducer

Purpose: To analyze the efficiency and cost-utility profile of ureteroscopy versus shock wave lithotripsy for treatment of reno-ureteral stones smaller than 2 cm. Methods: Patients treated for urinary stones smaller than 2 cm were included in this study (n = 750) and divided into two groups based on technique of treatment. To assess the cost-utility profile a sample of 48 patients

Cavitation appears to contribute to tissue injury in lithotripsy. Reports have shown that increasing pulse repetition frequency [(PRF) 0.5-100 Hz] increases tissue damage and increasing static pressure (1-3 bar) reduces cell damage without decreasing stone comminution. Our hypothesis is that overpressure or slow PRF causes unstabilized bubbles produced by one shock pulse to dissolve before
