Fat layer measuring device and method using ultrasound {APPARATUS AND METHOD FOR MEASURING FAT LAYER USING ULTRASOUND}

The present invention relates to a technique for measuring the thickness of a fat layer using ultrasound, and more particularly, to detect the pressure of an ultrasound probe on a liposuction site and measure the fat layer using ultrasound to ensure objectivity for the fat thickness measured by ultrasound It relates to an apparatus and method.

Recently, as modern people invest heavily in improving their external appearance, the number of people who undergo plastic surgery, such as plastic surgery, liposuction and procedures, is rapidly increasing. In particular, liposuction is a surgery that many people are interested in for health and treatment purposes as well as cosmetic purposes. In liposuction, a cannula is generally inserted into the fat layer and the fat formed in the cannula is suctioned and removed alone. In other words, liposuction is a procedure in which a cannula is inserted into the fat layer, which consists of the skin layer, fat layer, and muscle layer, to suction and discharge the fat. It can remove fat from the abdomen, thighs, buttocks, arms, as well as the face, and is also used for lipoma removal. It is becoming.

The basic goal of such liposuction is to reduce the fat distributed in the fat layer, and therefore the fat layer must be thin. In particular, fat thickness is an important part when performing liposuction. Previously, the fat layer was measured before and after surgery and measured with calipers to check how thick the fat was. In liposuction, it is important how thick the fat is left, and if too much is removed, side effects may occur.

Recently, during liposuction, ultrasound is being used to determine the thickness of the fat layer and the aspect of the fat layer at the extraction site. However, the thickness of the fat confirmed by ultrasound may vary considerably depending on how much pressure the person operating the ultrasound applies. For example, even if the same fat layer is targeted, 3-4 cm may become 1 cm depending on the pressing pressure.

Therefore, the need for a technique capable of securing objectivity for fat thickness confirmed by ultrasound has been required.
