  ESWL-B-I Medical Pneumatic Extracorporeal Shock Wave Lithotripsy Equipment  

 

 

Function

Extracorporeal shock wave lithotripter (ESWL) is a non-invasivetreatment device of kidney stones (urinary calculus) using an acoustic pulse (extracorporeal shock wave) to break a large stone into smaller pieces that can pass

 

Although calculus, especially calcium stones are very hard, most of the 20% to 30% that do not pass out of the body on their own can be eliminated without surgery. The process called lithotripsy (from the Greek word for "stone crushing") breaks into tiny fragments most stones that are less than three-quarters of an inch across.

 

Repeated shock waves cause the kidney stone to disintegrate into tiny particles. These particles pass easily out of the body in the urine.

 

The New Generation Lithotripter

• Brand New Shall Design.

• More Visualize Therapy Way

• Optimal Electromagnetic Shockwave Generator

• More User-friendly Localization Logistic

 

Easier localization method. Transform the complicated localization process to a very easy way, just like using ultrasound machine for examination. The patent localization system can complete the calculus localization quickly by microcomputer measurement and display system.

 

Overhead type Arm Control

• The reflector and localization system work together with the novel arm, Doctor can adjust the arm to check the patient, just like check the patient by himself.

• Unlike the traditional way of keyboard control, the overhead type arm control method is more intuitive

 

 

Multi-angle, Omni directional No blind zone Treatment

• The generator can move up and down, back and forth, rotate and swing.

• The treatment bed can also move up and down, left and right, No dead corner, No blind zone.

 

Digital Tracking Fast Localization System (Patent of our proprietary intellectual property rights)

• The fast localization system with ultrasound is small and convenient.

• The shockwave generator move along the focal point, while the digital measuring system keeps tracking the calculus.

• The ultrasound probe moves together with the localization system. The doctor can watch the treatment status simultaneously on the ultrasound monitor and decide whether to adjust the focal point at any time, thus realizing high hit rate and high work efficiency.

• Unlike traditional and fussy manual handle localization system, our digital tracking fast localization system is swift and easy.

 

Shockwave Generator Guarantee System

• Shock wave auto vacuum-pumping system ensures the high efficiency of the shockwave energy.

• Auto circulating water cooling system and generator auto air exhausting system ensure the long service life of shockwave generator.

• Diaphragm rupture auto alarm system minimizes the cost of consumption part.

 How it works

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.

 

The successive shock wave pressure pulses result in direct shearing forces, as well as cavitation bubbles surrounding the stone, which fragment the stones into smaller pieces that then can easily pass through the ureters. The process takes about an hour. A ureteral stent (a kind of expandable hollow tube) may be used at the discretion of the urologist. The stent allows for easier passage of the stone by relieving obstruction and through passive dilatation of the ureter.

extracorporeal lithotripsy works best with stones between 6 mm and 20 mm in diameter that are still located in the kidney and ureters.

 

 

The patients undergoing this procedure can, in some cases, see for themselves the progress of their treatment. If allowed to view the monitor, they may be able to see their stones change from a distinct bright point (or dark spot depending on whether the fluoro unit is set up in native or bones white) to a fuzzy cloud as the stone is disintegrated into a fine powder.

 

The passage of stone fragments may take a few days or a week and may cause mild pain. Patients may be instructed to drink as much water as practical during this time. Patients are also advised to void through a stone screen in order to capture stone fragments for analysis.
