The appearance of the treatment bed should be stable, beautiful and elegant, the color should be simple and elegant, so that patients can feel comfortable and warm, and the overall vision should be concise, so as not to make patients feel afraid. The treatment bed should not be too high, patients can go up and down freely, and it is convenient for medical staff to operate, maintain and clean.
The console of the electric control system should be simple and intuitive, the function keys should be reliable to touch, the characters should be clear, and there should be a luminous display, so that medical personnel can see clearly in a dark room or in complete darkness.

There are two options for shock wave launch cup in China.
Electro-hydraulic shock wave launching cup
Both kinds of shock wave launch cups have good lithotripsy effect, among which the electro-hydraulic shock wave launch cup has developed earlier and its technology is relatively mature, and has been widely used in clinic for nearly 20 years.
The electro-hydraulic shock wave launching cup is a shock wave generated by high-voltage spark discharge, and the stones are crushed by the focus of the launching cup. It is characterized by high efficiency through the discharge of replaceable electrodes, and medical staff can adjust the energy of gravel according to the size and hardness of stones, so that stones can be crushed quickly and effectively.
When choosing the electro-hydraulic shock wave launch cup, it depends on whether it is a small-caliber launch cup or a large-caliber launch cup. Nowadays, small-caliber launch cups are rarely used in clinic. The large-caliber emission cup has the advantages of large reflection area, high energy utilization rate, good crushing effect, low power consumption and convenient electrode replacement.
The electromagnetic shock wave launching cup is a spark-free shock wave launching cup invented in recent years. It generates magnetic energy by discharging the electric disc with high voltage, which attracts the metal plate to vibrate, and then generates shock wave, which is focused by the lens and breaks the stone. Its effect is slightly lower than that of electro-hydraulic shock wave launching cup, but it has long service life, low noise, no need to change electrodes, and is also very popular with medical staff.
When the electromagnetic shock wave launching cup is used in clinic, it is necessary to cool the cup with circulating water to ensure that the positioning focus is error-free. The launch cup also needs to be replaced. After the impact of about 6,543,800 times, the focus has failed, and the manufacturer needs to send someone to replace it.
Integrated positioning and launching device is the core part of the treatment process of stone crusher, and it is also the key technology developed by stone crusher manufacturers every year. When choosing to buy a stone crusher, you must consult and understand the integrated positioning and launching system of the product.
In the early days, the emitter was manually positioned, that is, after B-ultrasound scanned the stone image, the medical staff had to repeatedly adjust the position of the emitter and the B-ultrasound probe according to the depth of the stone in the image, so that the emitter cup could be accurately positioned on the stone. In this way, medical staff need special operation training and clinical practice to master it.
This comprehensive operation technology of B-ultrasound positioning.
Nowadays, the positioning system of new products has developed into a digital positioning mode. Medical staff can easily press the button on the operation panel to adjust the number to the same as the stone depth measured by the B-ultrasound probe, so as to accurately locate the whole transmitter and treat the patient.
Therefore, before buying, it is necessary to know whether the "integrated positioning launcher system" has realized digital simple operation in high-end products, so as to locate quickly and conveniently.
Regarding the choice of "double pulse" function, the principle of double pulse function is to add a set of high voltage discharge system in the stone crusher, which is triggered twice in a very short time to generate a secondary spark, forming a double pulse or called "composite pulse".
Adding the function of double pulse shortens the treatment time and improves the treatment speed of lithotripsy compared with "single pulse", but the machine manufacturing also increases a lot of costs.
