[0049] like Figure 1As shown in Figure 25, the treatment device based on focused ultrasound therapy provided by this invention includes a treatment probe 1000 for treating a treatment surface and a handle 2000 for providing power and control. The treatment probe 1000 is connected to the handle 2000 via a snap-fit ​​connection. By controlling the power component in the handle 2000, the ultrasonic transducer is driven to rotate in a circular trajectory and extend in a linear trajectory. The ultrasonic transducer focuses and outputs energy according to the circular and linear trajectories to perform cosmetic treatment on the treatment surface. This treatment device has a simple structure, and its split design allows for the use of multiple treatment probes on a single handle. Energy output is achieved through changes in the circular and linear trajectories, resulting in a wide treatment area and adjustable output distance between the treatment surface and the transducer.

[0050] The treatment probe 1000 includes a transmission assembly, a transducer assembly, a control circuit board 21, and a housing assembly. The control circuit board 21 is installed inside the housing assembly and placed below the top decorative piece of the housing assembly. The transducer assembly is installed inside the housing assembly and placed at the bottom of the cavity of the housing assembly. One end of the transmission assembly passes through the top and middle of the housing assembly and is connected to the transducer assembly at the bottom by screws. The signal output terminal of the control circuit board 21 is connected to the signal input control terminal of the transducer assembly. The transducer assembly operates according to the received control signal. During its operation, the power transmitted by the transmission assembly moves in a circular trajectory through the eccentric assembly, so that the energy output by the transducer moves along the circular trajectory during the treatment, expanding the treatment area. This eliminates the need for the user to frequently move the handle to expand the treatment area during treatment.

[0051] The transducer assembly includes a transducer 13 and an eccentric support 14. The transducer 14 is installed on the eccentric support 14 by a snap-fit ​​method, and the eccentric wheel principle is used to realize the circular trajectory treatment of ultrasound.

The upper plate 143 covers the top of the ring column 141, and the eccentric platform 144 is disposed on the surface of the upper plate 143. The two snap-fit ​​connectors 142 are respectively disposed on the ring column 141 and are symmetrically arranged. The top surface of the eccentric platform 144 has a groove 145, the inner wall of the groove 145 has symmetrically eccentric planes, and the bottom surface of the groove 145 has a through hole at its center. The upper plate 143 also has a through hole. This support has a simple structure and can effectively convert the power transmitted by the rotating shaft to drive the transducer to perform circular motion, thereby expanding its coverage area.

[0053] The transmission assembly includes a rotating shaft 16, a shaft seal 17, a return spring 18, a return torsion spring 15, and a cover plate 19. The bottom end of the rotating shaft 16 passes through the return spring 18, the shaft seal 17, and the return torsion spring 15 in sequence. The bottom end of the return torsion spring 15 passes through the rotating shaft 16. The top end of the rotating shaft 16 passes through the cover plate 19. The bottom of the cover plate 19 contacts the upper surface of the shaft seal 17. The return spring 18 is placed inside the cavity of the cover plate 19. The spring ensures that the vertical position is always in its original position, the torsion spring ensures that it can always be reset, and the shaft seal prevents water from entering the upper part of the inner shell. The rotating shaft 16 rotates alternately clockwise and counterclockwise according to a preset sequence. During use, the rotating shaft 16 returns to its default origin position via the return spring 18 and the return torsion spring 15, making it easy to align with the extended part of the motor shaft in the handle 2000.

Both the first and second motors are stepper motors or servo motors.

[0075] The housing assembly includes an upper shell 46, a lower shell 35, a light guide post 32, a light guide plate, a probe partition, and a heat dissipation ring post 33. The light guide post 32 is disposed inside the lower shell 35, and the light guide plate is disposed on the light guide post 32. The upper shell 46 and the lower shell 35 are connected by snap-fit ​​or screws. After the upper shell 46 and the lower shell 35 are connected, one end of the upper shell 46 is snap-fitted to the probe partition, and the other end of the upper shell 46 is snap-fitted to the heat dissipation ring post 33. The upper shell 46 and the lower shell 35 are fixed together by screws to make them more secure. The lower inner side of the lower shell 35 and the lower inner side of the upper shell 46 are respectively provided with a locking block. When the upper shell 46 and the lower shell 35 are snapped together, the two locking blocks are arranged symmetrically.

[0076] The electrical components include a main control PCB board and a probe PCB board. The probe PCB board is mounted on the probe partition, and the probes on the probe PCB board pass through the probe partition. The main control PCB board is communicatively connected to the probe PCB board. Decomposing it into two smaller boards makes the layout more convenient and allows for more efficient use of the internal cavity space.

[0077] The top of the rotating shaft 16 on the treatment probe 1000 is connected to the gripping rod 23 of the handle 2000. A magnet 162 is provided at the top of the rotating shaft 16, and a magnet is also provided inside the hanging rod. The magnetic attraction makes it difficult for the probe to fall off. The flat surface of the upper side wall of the rotating shaft 16 mates with the flat surface on the gripping rod 23 to prevent the gripping rod 23 from spinning freely. The upper end of the gripping rod 23 is connected to the shaft of the stepper motor 24.

[0078] Stepper motor 24 drives eccentric support 14 to rotate, thereby achieving circular trajectory rotation of transducer 13. Transducer 13 is fixed to eccentric support 14 and continuously emits focused energy, thus forming a circular treatment effect on the treatment surface. This treatment surface is much larger than a fixed point, offering a significant advantage.

[0079] The head of the gripper 23 contains a magnet and is an integral part of the medical handpiece. The rest of the part is the treatment probe module (this module is a replaceable component), which is connected to the handpiece via the snap-fit ​​202 of the treatment probe 1000.

[0080] To ensure precise connection between the treatment head and the gripper 23, and to achieve rotation without slippage, a flattened position is designed for both the rotating shaft 16 and the gripper 23. Simultaneously, the return torsion spring 15 always keeps the rotating shaft 16 in its radial position, and the return compression spring 18 always keeps the rotating shaft 16 in its axial position. Furthermore, magnets A and B provide continuous magnetic attraction (after completing the treatment, manually release the latch 202 and pull it outwards). Through these designs, accurate positioning and effective cooperation between the rotating shaft 16 and the gripper 23 can be achieved.

[0081] By changing the eccentric support model 14, various circular treatment trajectories can be achieved.

[0082] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
