Abstract

According to the present invention, disclosed is a treatment head of a non-invasive subcutaneous fat reducing device using high strength focused ultrasonic waves. A rotation angle of an HIFU transducer is gradually controlled in a longitudinal direction through a driving unit, and dose points are continuously formed at regular intervals, so a linear dose point combination is formed. Then, the HIFU transducer is a little bit moved in a transverse direction to repeat longitudinal irradiation in a backward direction, so a dose point combination of a two-dimensional matrix having a zigzag-shaped emission direction can be produced. Accordingly, a volume of fat tissue is determined, and a surface area corresponding to skin is recognized on the volume of the fat tissue. An HIFU treatment transducer is moved to the surface of skin, and a treatment in which subcutaneous is reduced while collagen fibrils having multiple necrosing and denatured organ cells are generated can be performed.

Description

TECHNICAL FIELD [0001] The present invention relates to a handpiece structure for a non-acupuncture subcutaneous fat reduction device using a high-intensity focusing type ultrasound,

The present invention relates to a handpiece structure of a non-acupuncture type subcutaneous fat reduction device using a high intensity focused ultrasound (hereinafter referred to as 'HIFU'), and more particularly, to a handpiece structure of a non-acupuncture type subcutaneous fat reduction device using a HIFU transducer Incremental control the rotation by, and forms a straight line projecting point combination, by forming a projecting point of the predetermined interval in a row, then repeated to thereby, with the irradiation direction of the jig zag form a vertically irradiated in the opposite direction a little by moving in the transverse direction The present invention relates to a handpiece structure of a non-acupuncture subcutaneous fat reduction device using a high-intensity focusing type ultrasonic wave, which enables a combination of irradiation points of a two-dimensional matrix .

Body sculpting has evolved to be one of the most sought after procedures to restore people to a slimmer, more refined physique, and the field of cosmetic surgery has evolved considerably in instruments and techniques.

Here, liposuction is one of the more popular methods for accelerating the body sculpting.

The liposuction technique is a method of body contouring that can dramatically improve the shape and appearance of different body regions by sculpting and removing unwanted fats. Recent innovations and developments in the field of liposuction are expanding Technology and ultrasonic assist technology.

Traditional liposuction is accomplished by making a small incision at the desired location and then inserting a hollow tube or conduit beneath the skin of the fat layer. The conduit is connected to a vacuum so that the fat escapes by vacuum. This procedure indiscriminately removes fat, connective tissue, blood vessels and nerve tissue.

In addition, such liposuction techniques can cause bleeding, bruising, trauma and blood loss, and the combination of these limits the amount of fat that can be safely removed in any given procedure .

The inflatable technique allows to remove considerable amounts of fat with less blood loss during surgery, and such inflatable liposuction techniques involve spraying saline and adrenaline solutions prior to suction.

Also, the conduit is used again with the suction device to remove the fat, and this procedure is to reduce the bleeding of conventional liposuction.

However, such liposuction techniques still remove considerable amounts of non-fat tissue, and the more sophisticated liposuction technique is Ultrasound Assisted Lipoplasty (UAL). The UAL adds a cannula (or probe) that oscillates at an ultrasonic frequency, similar to an inflatable technique, which vibrates a nearby volume fat cell to make it easier Liquefied for removal.

However, the UAL utilizes a low power suction and takes out the fat material only near the tip of the conduit, so it is more elaborate and also acts softly on the tissue, with less blood loss and less damage Less painful, and recovered fairly quickly, whereas all liposuction techniques are invasive and thus have the disadvantage of infecting and surgical risk for patients undergoing liposuction.

In addition, once the underlying tissue is removed, the skin may be loose or sagged or sagging, and in order to treat it, the patient may need to remove additional skin (by cutting the skin) It also had the disadvantage of choosing what to do, or choosing a skin tightening procedure to tighten the skin.

In addition to these invasive forms of liposuction, a number of other techniques have been disclosed in the prior art for treating unwanted fats (adipose tissue), including but not limited to creams, lotions, treatment procedures including lotions, garments, massage devices and techniques, and laser, RF or ultrasound equipment, general surgical procedures, drugs, and a number of home remedies.

However, none of the other techniques described above provide a one step solution for the patient, and typical of this is the multiple treatment before the patient is satisfied with the outcome, The prior art techniques and tools are designed for specific applications and also work within certain parameters for one desired result.

Thus, a single solution to the multi-step problem of eliminating or reducing the volume of unwanted tissue is highly desired, while simultaneously providing an improved cosmetic appearance without the need for a second or subsequent procedure have.

In addition, there is a need for a cost effective solution that provides a simple, fast, and effective method for achieving the desired objectives in one simple procedure, or for generating viable body sculpting procedures.

Accordingly, conventionally, HIFU equipment has been developed which is disclosed in, for example, Japanese Patent Application Laid-Open No. 10-1118480 (Published on March 12, 2012), Laid-Open Patent Publication No. 10-2012-0100049 The equipment can irradiate the ultrasound generated from the ultrasonic transducer at a certain point (focus) and irradiate the inside of the tissue to treat the cancer such as liver cancer, uterine cancer and breast cancer by the heat effect generated at the focus point (focus) As a device, it provides a selective local cancer treatment method which does not cause any injury or side effects to the human body and does not involve pain, and is also applied to treatment of skin-related wrinkles and the like.

In other words, the skin structure of the human skin is composed of the epidermis, the dermis, the subcutaneous fat layer, the muscle layer, and the skeleton in order. Most of the components of the dermis is a well-known protein called collagen that functions to maintain skin elasticity.
