Kidney stones are one of the most common urinary system diseases, and ureteroscopic holmium laser lithotripsy is an advanced treatment technique. Under the precise guidance of the ureteroscope and in conjunction with an endoscopic imaging transmission system, the holmium laser fiber can be accurately positioned near the kidney stones. 

The holmium laser is a high-energy pulsed laser with a wavelength of 2.1 μm, which has a penetration depth of only 0.4 mm, causing minimal damage to surrounding soft tissues. 

The principle of stone fragmentation is primarily based on the photoacoustic effect and photothermal effect: the photoacoustic effect generates microbubbles from water molecules absorbing laser energy, and the forces produced during their expansion or collapse shatter the kidney stones; the photothermal effect utilizes the energy of the holmium laser to raise the local temperature, thereby decomposing the kidney stones. 

In ureteroscopic holmium laser lithotripsy, continuous water flow infusion is essential, as it satisfies multiple needs, including stone fragmentation, cooling, and maintaining clear endoscopic imaging. 

Research indicates that excessively high infusion flow rates during the procedure can lead to increased pressure within the renal pelvis; once it exceeds 30 mmHg, it may trigger a series of serious complications, including renal fluid reflux, perinephric extravasation, infection spread, and even renal function impairment and sepsis. In severe cases, it can lead to infectious shock. 

Therefore, dynamically balancing the infusion flow rate with negative pressure suction flow during surgery is crucial.

Y Medical Company has launched an infusion-suction medical device as an important auxiliary tool for ureteroscopic holmium laser lithotripsy. 

This device is equipped with the CG series clamp-on ultrasonic flow sensor, which can accurately monitor key information in real-time, including the infusion flow rate within the renal pelvis, negative pressure suction flow rate, cumulative volume, and flow direction. 

Y Medical Company has further integrated this device with advanced temperature and pressure control technologies, intelligently adjusting the temperature and pressure within the renal pelvis, greatly enhancing the safety and efficiency of the procedure.

This groundbreaking medical device has brought revolutionary changes to kidney stone treatment. Additionally, the workstation of the infusion-suction medical device is capable of fully recording data such as imaging, flow rate, temperature, and pressure throughout the surgical process, providing a solid scientific basis for the optimization of subsequent surgical plans and further accelerating the innovation and advancement of kidney stone treatment technologies.
