Is the acquisition and use of a fat suction device permissible or forbidden, considering that it will be used for men and women, and the doctor will try as much as possible to work with local anesthesia to avoid uncovering 'awrah for women?

Liposuction is permissible out of necessity or a need that approximates it, such as body disfigurement or excessive weight causing harm, even if it entails uncovering the awrah (intimate parts), based on the Almighty's saying: "And He has already explained to you what He has forbidden to you, except for that to which you are compelled." The practitioner must be of the same gender, unless there is a necessity, while taking precautions to avoid looking at or touching what is not needed from the body. Accordingly, acquiring the aforementioned device is permissible, provided the mentioned rulings are adhered to.
