Patent Publication No. 10-2014-0011176 discloses an empty, pipe-shaped cannula that sucks fat from the skin of the human body, a handpiece connected to the rear end of the cannula, and a high-frequency current supply to the cannula. In the control box provided with a microcontroller and a power supply device, the first electrode and the second electrode are alternately wound in a spiral-shaped pair on an outer peripheral surface of an inner insulator of the cannula. Disclosed is a cannula for high-frequency liposuction surgery.

Patent Publication No. 10-2014-0040030 discloses that a separated space is formed as a longitudinal axis inside the pipe, and the space has a main pipe through which fat is sucked, and a main pipe with an arc-shaped partition wall on the inner circumference of the main pipe. Disclosed is a cannula for liposuction comprising at least one sub-pipe formed between the cross section and the partition wall, and a reinforcing material installed at any one of the sub-pipes to minimize the bending characteristics of the pipe.

Patent Registration No. 10-1502074 is a needle in which a hollow part is formed in a cylindrical shape in which both ends are opened in the longitudinal direction, and a chamber with a visible part formed on the outer surface is inserted through the hollow part. In the cannula for forming wrinkles on the skin, wherein the needle further has a suction hole on the side, is coupled to at least a part of the inner surface of the tip of the needle, and overlaps with at least a partial space of the lower space of the suction hole.

First, referring to FIG. 5, a method of controlling vibration of a cannula includes the steps of setting a temperature change according to a vibration frequency and a vibration period to be transmitted through an insertion tube of the cannula (P51); Determining a moving speed of the insertion tube and a reciprocating cycle of the insertion tube (P52); Detecting a temperature while transmitting a vibration according to the vibration frequency while the insertion tube is moved within the human body (P53); Detecting whether the temperature changes within a predetermined range (P54); And storing data on the temperature change according to the vibration transmission (P55).

A control unit 41 may be arranged to regulate the vibration of the cannula according to the present invention, and the control unit 41 may be part of an operation unit for operation of the cannula. The control unit 41 is based on the information transmitted from the operating device 47 and the operating database 46, such as, for example, a high-frequency electrode or a moving means of an insertion tube, and the vibration frequency of the vibration elements 451, 452, 453 , A vibration cycle or an appropriate temperature range may be determined and transmitted to the vibration setting unit 42 (P51). The vibration setting unit 42 sets the vibration conditions of each of the vibration elements 451, 452, 453 according to the information transmitted to the control unit, and at the same time sets and transmits the vibration cycle to the cycle unit 43. The vibration cycle is to determine the vibration order and vibration structure when a plurality of vibration plates 22a, 22b, 22c are disposed at different positions of the insertion tube. For example, if vibration is continuously applied, the temperature may increase rapidly, and if the insertion tube is moved forward, the induction vibration unit does not need to be vibrated. In addition, when the insertion tube is moved to the rear, the inflow vibration unit may not be vibrated. The vibration unit may be sequentially operated according to the moving direction of the insertion tube and the arrangement position of the vibration unit, and it is necessary to operate for a certain time. The cycle unit 43 can control such a vibration cycle of the vibration unit. In addition, the movement speed and movement period of the insertion tube may be detected by the cycle unit 43. The control unit 41 determines the moving speed and the reciprocating period of the insertion tube and transmits it to the setting unit 42 and the cycle unit 43 (P52), and the cycle unit 43 determines the movement speed and the reciprocating period of the insertion tube. It is possible to detect and accordingly operate the diaphragms 22a, 22b, 22c according to the vibration cycle. When the vibration elements 451, 452, and 453 are operated according to the set conditions, the vibration plates 22a, 22b, and 22c vibrate to transmit the vibration to the human body, and the temperature of the vibration area is adjusted to the temperature detection units 311, 312, 313 ) Can be detected (P53). In addition, the detected temperature may be transmitted to the control unit 41 by the danger detection unit 44. The danger detection unit 44 compares the temperatures between the temperature sensors 311, 312, and 313 disposed at different locations, and when the temperature of a specific area is different from that of other areas, or when the temperature changes abruptly. It may be determined as a situation and transmitted to the cycle unit 43. The cycle unit 43 may stop the operation of the vibration elements 451, 452, 453 or stop the movement of the insertion tube itself according to the danger information transmitted to the danger detection unit 44.

The control unit 41 may detect whether a temperature change is within a predetermined range based on the information transmitted from the danger detection unit 44 (P54). If the temperature range is not within the predetermined range (NO), the moving speed, reciprocating period, vibration frequency or vibration period of the insertion tube can be reset. On the other hand, if it is within a predetermined range (YES), related data may be stored and stored in the operation database 46 (P55). In addition, vibration and temperature correlation data is generated (P56), and the related data is stored in the operation database 46 to be applied to a liposuction procedure later.
