Ultrasound treatment device, control method and storage medium thereof

1 . A control method for an ultrasound treatment device, wherein the ultrasound treatment device comprises:

an ultrasound treatment tip configured to output ultrasound energy;

a displacement sensor provided on the ultrasound treatment tip or a handle portion of the ultrasound treatment device, and configured to collect displacement data of the ultrasound treatment tip; and

a contact sensor provided on the ultrasound treatment tip and configured to collect current contact data between the ultrasound treatment tip and corresponding human skin, and

wherein the control method comprises:

determining whether the ultrasound treatment tip moves according to current displacement data of the ultrasound treatment tip collected by the displacement sensor;

determining a contact state between the ultrasound treatment tip and the human skin according to the current contact data of the ultrasound treatment tip collected by the contact sensor; and

controlling the ultrasound treatment tip to start or stop outputting the ultrasound energy according to the current displacement data and the current contact data;

wherein the contact sensor comprises a pressure sensor, and the current contact data of the ultrasound treatment tip is current pressure data collected by the pressure sensor; and

wherein the determining the contact state between the ultrasound treatment tip and the human skin according to the current contact data of the ultrasound treatment tip collected by the contact sensor comprises:

determining a pressure difference between any two adjacent moments within a preset time period to obtain at least two pressure change values according to historical pressure data collected by the pressure sensor and the current pressure data; and

determining whether the ultrasound treatment tip slides in the treatment area according to the at least two pressure change values.

2 . The control method according to claim 1 , wherein the determining the contact state between the ultrasound treatment tip and the human skin according to the current contact data of the ultrasound treatment tip collected by the contact sensor comprises:

in response to determining that the current pressure data is greater than or equal to a preset pressure value, and the current displacement data is greater than 0, controlling the ultrasound treatment tip to output the ultrasound energy.

3 . The control method according to claim 1 , wherein the determining whether the ultrasound treatment tip slides in the treatment area according to the at least two pressure change values comprises:

in response to all the pressure change values being zero, determining that the ultrasound treatment tip does not slide in the treatment area; and

controlling the ultrasound treatment tip to stop outputting the ultrasound energy.

4 . The control method according to claim 1 , wherein the determining whether the ultrasound treatment tip moves according to the current displacement data of the ultrasound treatment tip collected by the displacement sensor comprises:

obtaining a moving speed value of the ultrasound treatment tip;

determining whether the moving speed value is greater than or equal to a preset moving speed value; and

in response to the moving speed value being greater than or equal to the preset moving speed value, determining that the ultrasound treatment tip moves.

5 . An ultrasound treatment device, comprising:

an ultrasound treatment tip configured to output ultrasound energy;

a displacement sensor provided on the ultrasound treatment tip or a handle portion of the ultrasound treatment device, and configured to collect displacement data of the ultrasound treatment tip;

a contact sensor provided on the ultrasound treatment tip and configured to collect current contact data between the ultrasound treatment tip and corresponding human skin; and

a controller configured to control the ultrasound treatment tip to start or stop outputting the ultrasound energy based on the control method according to claim 1 .

6 . A non-transitory computer-readable storage medium, wherein a control program for an ultrasound treatment device is stored on the non-transitory computer- readable storage medium, and when the control program for the ultrasound treatment device is executed by a processor, the control method for the ultrasound treatment device according to claim 1 is operated.
