Ultrasonic probe rod structure of extracorporeal shock wave lithotripter for urology department

Abstract

The invention discloses an ultrasonic probe rod structure of an extracorporeal shock wave lithotripter for urology department. The ultrasonic probe rod structure of an extracorporeal shock wave lithotripter for urology department comprises a shell and a supply box, a positioning assembly used for positioning a discharge electrode is arranged in the shell, a probe body is arranged on one side, close to the positioning assembly, of a bottom part of the shell, a waste box is arranged on one side, away from the probe body, of the bottom part of the shell, and the supply box is located between the waste box and the probe body. The ultrasonic probe rod structure is capable of automatically filling the discharge electrode, actively fills and replaces the electrode when the electrode needs to be replaced, thus solves a problem that an existing device has operation complexity since the electrode needs to be frequently replaced by medical personnel and meanwhile automatically collects the replaced discharge electrode. Besides, the ultrasonic probe rod structure solves a problem of focus drift by adjusting the position of the discharge electrode when a distance of an electrode tip is increased due to loss of a motor and has strong practicability.

Description

technical field [0001] The invention relates to the field of urology equipment, in particular to an ultrasonic probe rod structure of an extracorporeal shock wave lithotripter in the urology department. Background technique [0002] Ultrasonic lithotripsy uses electric energy to convert into sound waves, and the sound waves generate mechanical vibration energy in the ultrasonic converter, which is transmitted to the ultrasonic probe rod through the ultrasonic electrode, causing longitudinal vibration at the top, and produces a lithotripsy effect when in contact with hard stones. However, it does not cause damage to soft tissues, so as to achieve crushing of stones in the urinary system. The extracorporeal shock wave lithotripters developed and produced in my country all use hydraulic shock wave generators, which have the advantages of mature technology, stable pulse waveform, fast impact time, safety and reliability, and large energy. They are especially suitable for the tre...

Problems solved by technology

The disadvantage is that the electrode needs to be replaced frequently. Generally, the electrode needs to be replaced once to treat a patient. The replacement of the electrode is not only time-consuming, but also difficult to disassemble. focus drift
