Description

Technical Field

[0001] The utility model relates to the technical field of medical cosmetic instruments, in particular to an ultrasonic therapeutic instrument operating handle and an ultrasonic therapeutic instrument. Background Art

[0002] In recent years, the technology of non-invasive beauty treatment with focused ultrasound has been widely used. Ultrasonic therapy device is an instrument commonly used in beauty salons to implement this non-invasive beauty technology. It includes an ultrasonic therapy head assembly and a handle shell. When in use, the operator holds the handle shell and performs ultrasonic therapy on human skin through the ultrasonic therapy head assembly. An ultrasonic transducer is arranged inside the ultrasonic therapy head assembly. The ultrasonic transducer can emit ultrasonic waves forward. After being transmitted through the liquid sound-conducting medium, the ultrasonic waves irradiate the subcutaneous tissue of the human body, reach multiple layers such as the lower dermis, the superficial fat layer, and the SMS fascia layer, and gather on the central axis of the ultrasonic transducer to form a "thermal condensation point" with a temperature of up to 50-70°C, which plays a role in shrinking the aged collagen, stimulating the proliferation and reorganization of collagen, restoring the elasticity of the skin, and achieving the effect of tightening and lifting.

[0003] The position of the existing ultrasonic transducer inside the ultrasonic treatment head assembly is relatively fixed. Therefore, when the operator uses the existing ultrasonic treatment device to perform ultrasonic treatment on human skin, if the ultrasonic treatment head assembly is kept fixed at a certain place on the skin, the ultrasonic transducer of the ultrasonic treatment head assembly will also be fixed at that place and emit ultrasonic waves to irradiate the position on the subcutaneous skin, so as to avoid excessive ultrasonic irradiation of the subcutaneous tissue at that place due to the ultrasonic transducer staying at a certain place on the skin for a long time, causing safety problems. This is a test of the operator's experience and skills. If the operator is not careful, it will easily cause thermal damage to the subcutaneous tissue.

[0004] The Chinese utility model patent with patent announcement number CN117462861A discloses an adjustable ultrasonic treatment handle shell. This prior art can change the distance between the transducer and the ultrasonic membrane by adjusting the components to make the transducer move linearly inside the treatment head, adjust different focal plane depths, and achieve treatment effects at different depths under the skin. However, this prior art still has structural deficiencies. It can only drive the transducer to move linearly inside the treatment head, keep the treatment head staying at a certain place on the skin for a long time, and the ultrasonic transducer will also stay fixed at a certain place on the skin for a long time, which can easily cause the subcutaneous tissue at that place to be over-irradiated, and the treatment process is safer.

[0005] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0006] In view of the problems of the prior art, the utility model provides an ultrasonic therapeutic instrument operating handle and an ultrasonic therapeutic instrument. An eccentric driving component is provided in the handle shell, and the eccentric driving component can be used to drive the ultrasonic transducer to rotate eccentrically. When ultrasonic treatment is performed on human skin, the "heat condensation point" formed by the ultrasonic transducer irradiating the subcutaneous tissue can change the action position of the subcutaneous tissue with the eccentric rotation of the ultrasonic transducer. Even if the ultrasonic treatment head is kept fixed at a certain place on the skin, the ultrasonic transducer will not stay at a certain place on the skin for a long time. This can avoid excessive radiation and thermal damage to the subcutaneous tissue at that place caused by the ultrasonic transducer staying at a certain place on the skin for a long time, and the treatment process is safer.
