Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of main structure of ultrasonic pneumatic ballistic lithotripsy system, belong to lithotripsy medical instrument technical field. BACKGROUND

[0002] Urolithiasis is a common disease in China, with a high recurrence rate. The commonly used endoluminal lithotripsy methods include pneumatic ballistic lithotripsy, ultrasonic lithotripsy and holmium laser lithotripsy, among which ultrasonic lithotripsy can simultaneously perform stone crushing and clearing, significantly improving the efficiency of stone crushing and clearing and shortening the operation time. Meanwhile, due to the negative pressure suction effect, the kidney can be maintained in a relatively low pressure perfusion state, reducing the incidence of postoperative severe infection complications. However, when encountering very hard stones, ultrasonic waves are not easy to break them. The advantage of pneumatic ballistic lithotripsy is strong stone crushing ability, but it can only be used under rigid endoscopy and cannot be used with ureteral flexible endoscopy. The supporting stone crushing rod has a large vibration amplitude, which can easily cause the stones in the upper ureter to run back to the renal pelvis, leading to stone crushing failure. In addition, the crushed stone fragments are too large to be completely powdered, and the stones need to be removed by flushing, foreign body forceps or ultrasonic suction after stone crushing. The ultrasonic pneumatic ballistic lithotripsy system can realize the combined use of ultrasonic lithotripsy and pneumatic ballistic lithotripsy, combining the advantages of the two stone crushing techniques, which can significantly improve the efficiency of stone crushing. Ultrasonic combined pneumatic ballistic lithotripsy has gradually become the most commonly used method for stone crushing and clearing in PCNL surgery, especially for large volume stones and infected stones.

[0003] The power consumption of the ultrasonic pneumatic ballistic combined stone crushing system is very high when both ultrasonic and ballistic energy are output simultaneously, especially the power amplifier module. The main machine generates a large amount of heat, and a cooling system is necessary to maintain normal operation. The common cooling system uses a fan and an open radiator for cooling. The existing method is to simply increase the size of the radiator and the matching fan, which results in excessive noise during equipment operation and rapid temperature rise of the circuit module, causing low stone crushing efficiency and even burning out of electronic components, thereby affecting the reliability of the equipment. Therefore, to some extent, it limits its wide application in hospitals. UTILITY MODEL CONTENTS

Preferably, the pneumatic ballistic adjustment module is arranged away from the front end of the power amplifier heat dissipation module.

[0009] Further, the heat sink comprises a plurality of parallel arranged heat dissipation fins, the heat dissipation fins located at the front end of the power amplifier device being uniformly and spacedly arranged; among the heat dissipation fins located at the rear end of the power amplifier device, the heat dissipation fins in the middle part have a larger spacing than the heat dissipation fins in the edge part.
