Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic treatment, in particular to an ultrasonic treatment device with adjustable treatment depth. Background Art

[0002] In the ultrasonic treatment devices currently on the market, the transducer in the treatment head is driven by a driving mechanism such as a screw motor to achieve longitudinal or lateral movement of the transducer unit. However, the driving mechanism does not have a guiding function, which causes the ultrasonic transducer unit to tilt or swing easily during the movement of the transducer, causing the focus of the ultrasonic waves emitted by the transducer to deviate from the target area, seriously affecting the treatment effect.

[0003] The patent with application number "202321125724.X" and patent name "Ultrasonic Therapeutic Head and Ultrasonic Therapeutic Device" discloses an ultrasonic therapeutic head, including a shell, a bracket, an ultrasonic transducer unit and a driving mechanism, wherein the shell forms an inner cavity with a treatment window, and an input hole connected to the inner cavity is provided on the outer side of the shell; the bracket is movably arranged in the inner cavity; the ultrasonic transducer unit is connected to the side of the bracket facing the treatment window; the driving mechanism is installed on the outside of the shell, and the driving end of the driving mechanism is connected to the bracket through the input hole, and the driving mechanism drives the bracket to drive the ultrasonic transducer unit to move; a guide structure, wherein the guide structure is arranged in the inner cavity, and the guide structure is connected to the side of the bracket away from the ultrasonic transducer unit, and the guide structure is used to guide the movement of the bracket. This application can maintain the stability of the movement of the ultrasonic transducer unit and ensure the treatment effect.

[0004] However, the guide structure in this patent is arranged on the bracket of the transducer, and the guide structure as a whole moves with the transducer, which increases the load on the drive motor and affects the service life of the motor. In addition, the telescopic rod is used as the guide moving part, and a guide hole is arranged on the cover body. The position where the telescopic rod and the guide hole match needs to be sealed, which increases the difficulty of sealing the inner cavity of the treatment head. In addition, in order to ensure that the telescopic rod and the guide hole have good guiding accuracy, it is necessary to increase the thickness of the cover body, or add a boss separately at the position of the guide hole of the cover body, which undoubtedly increases the design complexity of the treatment head structure.
