1. Technical Field
The present invention relates to a probe transducer structure, and more particularly to a shockwave probe transducer structure capable of achieving for shockwave lithotripsy.
2. Description of Related Art
Ultrasonic or shockwave detection refers to “the detection of flaws in a human body or an object by low-energy high-frequency ultrasound”. The high penetration of the ultrasound or shockwave can detect a very thick object. In addition, the shockwave detection using ultrasounds has no harm on human body and is capable of determine the internal flaws of the object immediately, and this is the major advantage of the shockwave detection.
The general ultrasonic or shockwave detection adopts a frequency from 1 MHz to 25 MHz, and basic equipment requires an electronic signal generator or uses a transducer (or a shockwave probe, a transducer of probe or a search unit) to emit ultrasound or shockwave. The ultrasound or shockwave is sent into a human body or an object by couplings. The ultrasound or shockwave in the human body or object may be deteriorated to a certain extent, so that when the ultrasound or shockwave is transmitted to the an interface of a substance, the ultrasound or shockwave is reflected or transmitted, and the reflected or transmitted signal is detected and analyzed to determine a flaw of the human body or object and the position of the flaw.
In the ultrasonic or shockwave detection, it is necessary to change the whole set of the shockwave probe in order to change the focal point of a conventional shockwave probe, and thus requiring a complicated changing procedure and taking much effort and precious treatment time. Since most ultrasonic or shockwave systems are connected to a water filling structure and a complicated and high-pressure pipeline, water will leak easily or even damage the expensive ultrasonic or shockwave system will be damaged if the whole set of the ultrasonic probe is changed.
In view of the aforementioned problems, it is an urgent and important subject for related manufacturers to design and develop a shockwave probe transducer structure having the features of changing the focal point of the ultrasound or shockwave by a simple procedure and preventing water leakage to benefit medical ultrasonic or shockwave equipment users.
The present invention relates to a shockwave probe transducer structure comprising: a shock cup; a magnetic disc; and a focusing module, wherein the focusing module includes a circular cover and a focusing member fixed and installed between the circular cover and the shock cup, and the focusing member is consisted of a focusing bag, or a lens and a focusing bag closely coupled to one another. With the implementation of the present invention, the focal point of the shockwave of the shockwave probe transducer structure can be changed by simply changing the focusing module installed at the front of the shockwave probe transducer structure, so as to overcome the problems of complicated changing procedure and possible water leakage and avoid the risk of damaging an expensive shockwave system or jeopardizing the safety of people.
The present invention provides a shockwave probe transducer structure, comprising: a shock cup, including a housing, a first opening, a second opening configured to be opposite to the first opening, and a fixed disc capable of detachably sealing the second opening; a magnetic disc, installed on the fixed disc in the housing, and having a shock plate fixed onto a surface of the magnetic disc proximate to the first opening; and a focusing module, detachably sealed and fixed onto the first opening, and a gap filled up with a medium being formed between the focusing module and the magnetic disc, and the focusing module including a circular cover and a focusing member installed between the circular cover and the shock cup, and a portion of the focusing member being extended and protruded out from the circular cover,
Implementation of the present invention at least involves the following inventive steps:
1. The modularization of the shockwave probe transducer structure simplifies the complexity of changing the focal point of the shockwave significantly;
2. The shockwave probe transducer structure is capable of avoiding water leakage to prevent the expensive ultrasonic or shockwave system from being damaged by water leakage; and
3. The shockwave probe transducer structure is capable of avoiding jeopardizing the safety of people when changing the focal point of the shockwave.

Therefore, the amplitude or frequency of the voltage waveform outputted to the magnetic disc 120 by the control circuit 90 may be selected to adjust and control the magnitude or frequency of the shockwave 200 generated by the shockwave probe transducer structure.
The focusing member 132 just having the lens 70 and the focusing bag 80 or the focusing member 132 just having the focusing bag 80 is provided for focusing and emitting the shockwave 200 to the outside. We simply need to change the focusing module 130 including the circular cover 131 and the focusing member 132 in order to change the focal point of the shockwave 200.
