The probe sealing ring 25 further fixes the ultrasonic imaging probe 23 and enhances the sealing performance at the ultrasonic imaging probe 23. The therapeutic pot body 21 is provided with a plurality of transducer mounting holes 212, and the disc seat 2211 is fixed on the transducer mounting holes 212 and is in concave-convex fit with the transducer mounting holes 212.

The peripheral side wall of the treatment pot body 21 is provided with a sealing groove 216, and the end part of the water sac cover 24 is fixed on the sealing groove 216 through a sealing press ring. The sealing press ring is matched with the sealing groove 216, so that the water sac cover 24 and the treatment pot body 21 can be fixed, and a better sealing effect can be achieved. The treatment pot body 21 is provided with a water inlet 214 and a water outlet 215 so as to be convenient for filling or replacing water in time.
As shown in fig. 12, a therapeutic device capable of generating shock waves or ultrasonic waves is described as follows, wherein 8 piezoelectric transducer assemblies 22 are mounted in a piezoelectric transducer head 2.
S1: the controller 1 is operated to inject degassed water from the water treatment system 3 into the same piezoelectric transducer treatment head 2, so that the water bag cover 24 is internally filled, and the outer surface of the water bag cover 24 is coated with an ultrasonic couplant for contacting with the skin of a human body.
S2: the ultrasonic image probe 23 in the same piezoelectric transducer treatment head 2 emits ultrasonic images, and the ultrasonic images sequentially pass through the degassed water, the water sac cover 24 and the human skin and enter the internal tissues of the human body.
S3: the ultrasonic image diagnostic apparatus 4 is connected with the ultrasonic image probe 23, and the focus point information of the internal tissue of the human body is acquired through the ultrasonic image diagnostic apparatus 4, wherein the focus point information comprises focus points confirmed by the ultrasonic image diagnostic apparatus 4, measured sound field coordinate data of the focus points and the distance between the focus points and the surface of the ultrasonic image probe 23. After acquiring the information of the focal point, the ultrasonic image diagnostic apparatus 4 transmits the information of the focal point to the controller 1.
S4: the controller 1 transmits the received focal point information to the positioning motion system 7 and activates the positioning motion system 7.
S5: the positioning motion system 7 moves the focus point to the axial line of the ultrasonic image according to the received focus point information, and the distance between the focus point and the surface of the ultrasonic image probe 23 is equal to the distance between the surface of the ultrasonic image probe 23 and the treatment focus. When the distance between the focus point and the surface of the ultrasonic imaging probe 23 is equal to the distance between the surface of the ultrasonic imaging probe 23 and the treatment focus point, the treatment focus point and the focus point are overlapped, and the positioning motion system 7 sends the information of the coincidence of the treatment focus point and the focus point to the controller 1.
S6: after receiving the information fed back by the positioning motion system 7, the controller 1 judges whether to adopt ultrasonic wave or shock wave treatment according to the information of the focus point on the controller 1.
When shock waves are used for treatment, the following operations are adopted:
s7: the controller 1 starts the high frequency and high voltage pulse system 6.
S8: the high frequency, high voltage pulse system 6 closes the shock wave switch on the acoustically driven switch 8 and sends an electrical signal of the shock wave to the second ceramic disc 223 in the same piezoelectric transducer treatment head 2.
S9: the second ceramic disc 223 in the same piezoelectric transducer treatment head 2 receives the electric signal of the shock wave to generate the shock wave, and then the shock wave is emitted out through the first positive polarization surface 2221, and the shock wave sequentially passes through the degassed water, the water sac cover 24 and the skin of the human body and enters the internal tissues of the human body to perform shock wave treatment.
Specifically, when performing shock wave therapy, high-voltage pulse electrical signals are connected to the second electrode wires and the third electrode wires on 8 piezoelectric transducer assemblies 22, and if the high-voltage pulse electrical signals are 1mS, shock waves with a pulse width smaller than 1us are generated on the second ceramic disc 223, and the shock waves are emitted through the first positive polarization surface 2221. When 5-10KV voltage is set, the peak value range of output sound pressure of the single same-body piezoelectric transducer assembly 22 is 2-7Mpa, and the same-body piezoelectric transducer treatment head 2 generates total energy of (2-7) multiplied by 8 Mpa.
When the ultrasound is used for the treatment, the following procedure is used:
s10: the controller 1 activates the ultrasonic power source system 5.
S11: the ultrasonic power source system 5 closes the ultrasonic switch on the acoustically driven switch 8 and sends an electrical signal of the ultrasonic waves to the first ceramic disk 222 in the piezoelectric co-piezoelectric transducer treatment head 2.
S12: the first ceramic plate 222 in the treatment head 2 of the same piezoelectric transducer receives the electric signal of the ultrasonic wave to generate ultrasonic wave, and then the ultrasonic wave is emitted out through the first positive polarization surface 2221, and the ultrasonic wave passes through the degassed water, the water sac cover 24 and the skin of the human body in sequence and enters the internal tissues of the human body to carry out ultrasonic treatment.
Specifically, during the ultrasonic therapy, high-frequency ac signals are connected to the first electrode wires and the second electrode wires on the 8 piezoelectric transducer assemblies 22. If the high frequency ac signal is 0.5-2MHz, first ceramic disk 222 generates 0.5-2MHz ultrasonic waves and transmits 0.5-2MHz ultrasonic waves through first positive polarization surface 2221, and when a voltage of 30-300V is set, single piezoelectric transducer assembly 22 outputs a sound intensity of 20-300W/cm2, and piezoelectric transducer treatment head 2 generates a total energy of (20-300) × 8W/cm 2.
For patients who require both ultrasonic therapy and shock wave therapy, the therapy may be performed sequentially, for example, after step S6, shock wave therapy is performed using steps S7-S9, and then ultrasonic therapy is performed using steps S10-S12.
The numbers and parameter values in the description of the operation principle of the treatment apparatus are only for better describing the treatment apparatus and should not be construed as limiting the application.
The present application has been described with reference to specific examples, which are provided only to aid understanding of the present application and are not intended to limit the present application. For a person skilled in the art to which the application pertains, several simple deductions, modifications or substitutions may be made according to the idea of the application.
