It is possible that damage renal function, and recurrence rate is high.Therefore external supersonic rubble becomes broken since the injury to human body is less
The first choice of stone.However there are biggish impact forces for existing ultrasonic crushing technique, will cause a degree of tissue damage, and
Ultrasound lithotriptor has that the severe attrition of tool heads, calculifragous efficiency are low, the rubble time is grown.For this purpose, we have proposed one
Kind double duct ultrasound lithotriptor comes into operation, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of double duct ultrasound lithotriptors, to solve to propose in above-mentioned background technique
Existing ultrasonic crushing technique there are biggish impact forces, will cause a degree of tissue damage, and ultrasound lithotriptor
There is a problem of that severe attrition, the calculifragous efficiency of tool heads are low, the rubble time is grown.
To achieve the above object, the utility model provides the following technical solutions: a kind of double duct ultrasound lithotriptor, including pressure
Electroceramics handle, the side of the piezoelectric ceramics handle pass through ultrasonic electrode and connects with ultrasonic transducer, the ultrasonic electrode and
Ultrasonic feeler lever positioned at piezoelectric ceramics handle bottom end connects, and ultrasonic feeler lever through piezoelectric ceramics handle and with piezoelectric ceramics handle
The negative tube in outside is connected, the outer tube that the ultrasound feeler lever includes inner catheter and is socketed on inner catheter, the inner catheter
It is connected with the left end junction of outer tube by flexible connecting member, is formed by between the inner catheter and outer tube in gap uniformly
Elastic component is installed.
Preferably, the digitized chip for adjusting ultrasonic pulse and supersonic frequency is installed in the ultrasonic transducer.
Preferably, the piezoelectric ceramics handle uses the disinfection treatment of high temperature and pressure, and the ultrasound of piezoelectric ceramics handle is high
Frequency vibration is 20 kilo hertzs or more.
Preferably, the ultrasonic vibration frequency of the inner catheter is 21000 hertz, and the ultrasonic vibration frequency of the outer tube is
1000 hertz.
Compared with prior art, the utility model has the beneficial effects that the ultrasonic feeler lever of the utility model is by inside and outside two groups
Pipeline composition can generate the two kinds of effects of ultrasound and impact simultaneously, improve calculifragous efficiency, hollow inner catheter passes through vacuum suction
Calculus can effectively avoid the displacement of calculus during rubble.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model ultrasound feeler lever structural schematic diagram.
In figure: 1 piezoelectric ceramics handle, 2 ultrasonic transducers, 3 ultrasonic electrodes, 4 ultrasonic feeler levers, 41 inner catheters, 42 outer tubes, 43
