Optionally, the fixing ring 610 is clamped with the transducer body 500 through the quick-assembly rod 630, or a thread is formed in the quick-assembly rod 630, and the fixing ring 610 is connected with the transducer body 500 through a screw. The quick-fit bar 630 circumferentially and eighthly mounts the retainer ring 610 to the transducer body 500 to effect a seal between the retainer ring 610 and the transducer body 500.
Further, as shown in fig. 1-2 and fig. 6, the ultrasonic therapeutic apparatus further includes a bed connecting plate 80, the ultrasonic transducer adjusting mechanism 10 is fixedly disposed on the bed connecting plate 80, and the bed connecting plate 80 can be fixed on a bed. The MRI beds produced by a plurality of MRI manufacturers on the market at present have different shapes, and the ultrasonic therapeutic apparatus comprising the bed connecting plate 80 provided by the embodiment can be more simply and conveniently compatible with each set of MRI equipment. Furthermore, only a bed mounting plate for a compatible MRI bed needs to be made during design, so that the MRI bed can be well compatible with the MRI equipment to be compatible. The embodiments described above provide an ultrasonic treatment apparatus that is compatible with (i.e., passes through without obstruction) the scanning bore of an MRI device having a minimum diameter of 555mm (as is known, all MRI manufacturers have designs that reduce the increase in MRI bore due to the pressure caused by the bore being too small when performing MRI scans on patients, and some MRI scanning bores have been increased to a diameter of 700mm today).
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
