Summary of the invention
The purpose of this utility model is to propose the quick detent mechanism of a kind of extra chock wave lithotriptor, adopt this quick detent mechanism can thoroughly change the traditional station-keeping mode that calculus is moved to fixed wave source focal position by the method for mobile therapeutic bed or human body, but adopt the new station-keeping mode of mobile wave source, promptly mobile wave source makes its focus overlap with the calculus position, thereby overcomes the deficiencies in the prior art.
Design of the present utility model is such.Because present equipment, its wave source and Ultrasonic-B probe are separate, and wave source is fixed, so can only adopt the localization method of present mobile human body.The i.e. pattern of " fixedly wave source, mobile human body and probe repeatedly ".If wave source is designed to movably, and move it with Ultrasonic-B probe between have certain related, the focus of wave source can only be moved on the centrage of Ultrasonic-B probe, so as long as Ultrasonic-B probe finds the position of calculosis, just can go to seek calculus by mobile wave source, the i.e. pattern of " fixing human; translation wave source ", such locate mode was both simple, convenient, avoid the patient that turns from side to side repeatedly again, not only operated more humanely, and can improve alignment quality greatly, thereby the raising therapeutic effect is the revolution improvement to extra chock wave lithotriptor tradition locate mode really.
The quick detent mechanism of extra chock wave lithotriptor of the present utility model mainly comprises a shock wave source 1, a Ultrasonic-B probe 2, it is characterized in that this mechanism is provided with the mounting 9 that can do three-dimensional motion, and described Ultrasonic-B probe 2 is located on this mounting 9; Also be provided with a wave source frame 10 on this mounting 9, described shock wave source 1 is fixedly arranged on this wave source frame 10, and its focus is just on the centrage of Ultrasonic-B probe; Have one can make this wave source frame 10 make the drive mechanism 4 of linear translational motion along the centrage of Ultrasonic-B probe; On this mounting 9, be provided with one and can measure the range unit 6 that described wave source frame is shock wave source 1 displacement.
Advantage of the present utility model is: because detent mechanism of the present utility model does not need repeatedly mobile human body and B ultrasonic, as long as the moving shock wave wave source of translation, just can finish position fixing process, promptly finish the location by " deciding human body; the translation wave source " action, the locate mode of than before " fixing wave source; mobile human body and probe repeatedly " has had very much progress, no matter before the treatment or in the treatment, the doctor can adjust positioning accuracy easily, alleviated doctor's labor intensity, just guaranteed that also patient obtains treating more safely and efficiently.Position fixing process is directly perceived, simple and direct, convenient, has both alleviated doctor's workload, has improved positioning accuracy and therapeutic quality again.
