Description

[0001] High-frequency surgical liposuction cannulas [0002]

The present invention relates to a cannula for high-frequency liposuction surgery, and more particularly, to a cannula for high-frequency liposuction surgery, which generates deep heat inside a human body by using a high frequency power source so as to dissolve or smoothly change a fat layer .

Generally, liposuction is a surgical procedure in which the subcutaneous fat is sucked into the vacuum and discharged out of the body without damaging the nerve and lymphatic vessels.

As the standard of living improves, the consumption of meat increases, and as a result of the development of transportation, the number of movements such as walking decreases, so that the body accumulates a lot of animal fat which is not decomposed and causes obesity.

Such obesity is now recognized as one of the diseases, and especially causes arteriosclerosis and various adult diseases such as diabetes. If the fat accumulated in the body is not decomposed into regular exercise, it accumulates on the surface of adipose tissue or organ of subcutaneous tissue It causes a serious imbalance in the abdomen, thighs, calves or forearms by changing the body shape.

Meanwhile, the liposuction technique for changing the body fat into slim body is widely practiced by eliminating the fat accumulated in the human body by artificially removing the fat, and the liposuction machine which is a medical device for inhaling the fat is a cannula A handpiece to which the rear end of the cannula is connected, and a main body capable of adjusting the speed of the handpiece.

The cannula is formed into a hollow pipe shape, and the handpiece integrally formed with the cannula generates a vacuum suction force to suck the fat, and then is discharged to the outside through the connecting hose.

In particular, an electrode for supplying a high frequency (RF) current to a cannula is configured such that a high frequency current supplied from an external control box is directly connected to a cannula to control a high frequency current, Of the body, and a separate liposuction device is used to discharge the body fat to the outside.

Such a conventional cannula causes RF signals to propagate in the body, causing oscillation of ionic molecules or atoms in the body, and they are converted into heat energy by itself or colliding with each other, and are accumulated as a result of the radiation time. Therefore, when the generation temperature is controlled by adjusting the power and frequency of the RF signal, it is possible to obtain the effect of heat, dehydration, and destruction in the body tissue, which are used as the principle of blood circulation and fat removal, respectively.

Since the conventional electrode has a pipe-shaped cannula which is hollow inside itself serves as an electrode, when a high-frequency current is supplied, a considerably high energy is supplied and high heat is generated. Therefore, there is a possibility that the inside of the body is thermally damaged. In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2010-0135863 discloses that a coolant pipe is provided inside a cannula to supply saline water to lower the heat. Therefore, such an electrode method is complicated in structure and requires a separate refrigerant tube, so it is not suitable for a liposuction cannula because a liposuction operation is troublesome and a separate liposuction tube should be installed.

In addition, a high-frequency current is supplied to a plurality of electrodes disposed on the pad, the pad is inserted into the abdomen of the patient, and then a separate cannula is inserted into the body alone to suck and discharge the fat dissolved by the deep- The electrode pad and the cannula are required to be separately provided. Even if a high-frequency current is applied through the bipolar electrode from the outside of the abdomen of the patient, the deep heat is very weak and the liposuction treatment effect is insufficient .
