DETAILED DESCRIPTION

[0023] In order to facilitate those skilled in the art to understand and implement the present invention, the present invention is further described in detail below in conjunction with embodiments. The embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0024] Example 1:

[0025] A high-frequency ultrasonic fat emulsification instrument includes a high-frequency ultrasonic host 1, a ultrasonic emulsification treatment knife 7, and a radio frequency electrode 11. The high-frequency ultrasonic host 1 is provided with an ultrasonic output interface 3 and a high-frequency output interface 4. The radio frequency electrode 11 is connected to the high-frequency output interface 4 of the high-frequency ultrasonic host 1 through a radio frequency cable. The ultrasonic emulsification treatment knife 7 is connected to the output end of the transducer 5. The input end of the transducer 5 is connected to the ultrasonic output interface 3 of the high-frequency ultrasonic host 1 through an aviation plug 6. A plurality of annular grooves 9 are provided on the outer periphery of the blade head 8 of the ultrasonic emulsification treatment knife 7. The plurality of annular grooves 9 are uniformly arranged in sequence along the axial direction of the blade head 8. The front end of the blade head 8 of the ultrasonic emulsification treatment knife 7 is hemispherical. A plurality of strip electrodes distributed in an array are arranged on the contact surface of the treatment head of the radio frequency electrode 11. Specifically, the contact surface of the treatment head of the radio frequency electrode 11 has a plurality of evenly distributed electrode rows, and each electrode row includes a plurality of strip electrodes 12 distributed at equal intervals; a temperature sensor is also provided inside the treatment head of the radio frequency electrode 11.

[0026] The high-frequency ultrasound host 1 includes an ultrasonic output mode and a high-frequency output mode. When the ultrasonic mode of the high-frequency ultrasound host 1 is used for ultrasonic fat emulsification, the high-frequency ultrasound host 1 outputs an electrical signal of a frequency corresponding to the ultrasonic signal to the transducer 5. The transducer 5 converts the electrical signal into an ultrasonic signal, which is then input into the ultrasonic emulsification treatment knife 7. The ultrasonic emulsification treatment knife 7 performs fat emulsification on the corresponding part of the patient.

[0027] After fat emulsification, the rapid removal of subcutaneous fat will cause the skin to become loose, and it is usually necessary to wear a shaping garment for a period of time. The utility model has added a radio frequency function. After fat emulsification, radio frequency energy treatment can be used to accelerate the recovery of skin firmness and effectively shorten the operation cycle.

[0028] When using the high-frequency mode of the high-frequency ultrasound host 1 for skin firming restoration, the high-frequency ultrasound host 1 outputs a radio frequency signal to the radio frequency electrode 11 through the high-frequency output interface 4, and the radio frequency electrode 11 performs skin firming restoration on the corresponding part of the patient.

[0029] The front end of the blade head 8 of the ultrasonic emulsification treatment knife 7 is hemispherical, has no cutting edge, and is not sharp. It will not cause damage to normal tissue during use. The annular groove 9 opened on the blade head 8 can increase the contact area, improve the emulsification effect, and shorten the treatment time.

[0030] Compared with traditional sheet-like radio frequency electrode treatment heads, the array-distributed electrodes arranged on the contact surface of the radio frequency electrode 11 of the present invention can make the radio frequency current more evenly and fully distributed in the tissue, effectively avoiding damage caused by local overheating, and at the same time can more effectively activate and stimulate cells or tissues in the treatment area, heat the skin more evenly, promote collagen production and skin firming, and effectively improve the treatment effect; the radio frequency electrode 11 of the present invention is equipped with a temperature sensor inside the treatment head, which can monitor the skin temperature of the treatment area to avoid skin damage caused by excessive temperature.

The ultrasonic switch detection module 14 is used to detect the switch state of the ultrasonic foot switch. When the ultrasonic foot switch is detected to be in the on state, the ultrasonic switch detection module 14 outputs a first on state signal to the microcontroller 15. The microcontroller 15 reads the first on state signal and outputs a first on control signal to the ultrasonic signal generator 17. After receiving the first on control signal, the ultrasonic signal generator 17 generates an electrical signal of a corresponding frequency, which is then input into the transducer 5 through the ultrasonic output interface 3; when the ultrasonic foot switch is detected to be in the off state, the ultrasonic switch detection module 14 outputs a first off state signal to the microcontroller 15. The microcontroller 15 reads the first off state signal and outputs a first off control signal to the ultrasonic signal generator 17. The ultrasonic signal generator 17 stops working after receiving the first off control signal;
