High-intensity focused ultrasound device

Abstract

The present invention relates to a high-intensity focused ultrasound device, and more specifically, to a high-intensity focused ultrasound device which has a structure changed so as to enable a disposable separable cartridge to be attached and detached, and which enables a doctor, who is the person performing a procedure, to obtain, through a scanning unit of a transducer for ultrasonic conversion, coordinates of a skin tissue of a subject undergoing the procedure, thereby allowing for an accurate procedure point to be checked in real time, thus allowing for a procedure to be performed on an accurate point on a skin tissue, without repeated procedures. The present invention relates to a high-intensity focused ultrasound device comprising a hand piece comprising: a hand piece body electrically connected by a wire to a freely movable moving body; and a separable cartridge disposably coupled to the hand piece body. The hand piece body comprises: a laser generator which fractionally transfers energy so as to facilitate the synthesizing of collagen; a transducer for ultrasonic conversion which receives electrical energy that has been impedance-matched by going through the processes of frequency generation and power amplification, converts the electrical energy into high-intensity focused ultrasound and irradiates same, or which receives reflected ultrasound; and an X-Y reflection mirror which undergoes in parallel a forward / backward movement and a tilting movement inside the hand piece body, and consecutively forms HIFU foci in a single row, or consecutively forms HIFU foci in aplurality of rows, or consecutively forms foci in a circular shape; a cooling device which supplies cooling gas to the separable cartridge; and a zoom-in device which zooms-in an image formed by thereflected ultrasound. The separable cartridge comprises: a cooling passage which enables cooling gas to be injected and to flow on the bottom surface of the separable cartridge, thereby lowering the temperature; and a transparent transmittance member which supports the cooling passage, and adheres to a skin tissue so as to enable the laser and the high-intensity focused ultrasound to pass throughand reach the skin. The moving body comprises: a control unit comprising a transducer for ultrasonic conversion-module, a reflection mirror control module, a cooling module and a coordinate module, the transducer for ultrasonic conversion-module controlling the processes of frequency generation and power amplification of the transducer for ultrasonic conversion, and controlling power, frequency, duty cycle, focus size and pulse repetition frequency, the reflection mirror control module controlling the forward / backward movement and the tilting movement of the X-axis and the Y-axis of the reflection mirror, the cooling module lowering the temperature of the cooling device if re-treatment is performed, and the coordinate module receiving information on coordinates converted through the transducer for ultrasonic conversion, and figuring out a site that is currently being treated; a monitor unit comprising an indicator for indicating information related to a procedure of a person performingthe procedure, and a touch screen for the person performing the procedure to operate or control the high-intensity focused ultrasound generation device; and a power unit for supplying high-intensityfocused ultrasound power.

Description

technical field [0001] The present invention relates to a high-intensity focused ultrasound device. More specifically, it relates to a structure in which a disposable separable cassette can be detached and assembled, and the operator, that is, a doctor, can scan with a transducer through ultrasonic conversion. It is a high-intensity focused ultrasound device that can obtain the coordinates of the skin tissue of the surgical object by using a part to confirm the exact surgical location in real time, and perform surgery at the exact surgical location to avoid repeated operations. Background technique [0002] Generally speaking, High Intensity Focused Ultrasonic surgical unit (HIFU) is a technology that irradiates the ultrasonic waves generated in the transducer into the tissue, so as to use the heat energy generated by the focal point (focal point) for treatment. It is used in the treatment of liver cancer, breast cancer, uterine cancer, etc. Apply this principle to skin bea...

AI Technical Summary

Problems solved by technology

[0004] However, due to the limited lifespan of high-intensity focused ultrasound generating devices, medical consumers who perform treatments for cosmetic purposes are exposed to higher surgical costs

[0005] In addition, although ultrasonic energy can be transmitted to a depth of 3-4.5mm below the skin surface (SMAS layer) to tighten the skin, it is difficult to achieve rapid healing due to the inability to regenerate a large amount of collagen at the same time

[0006] In addition, the service life is limited by the output of ultrasonic waves, etc., so when using an ultrasonic surgical device, it is necessary to periodically replace the separate cassette

[0007] At this time, due to the output of high-intensity focused ultrasonic waves, high heat will be generated on the transducer and cassette PCB of the separate cassette and the main PCB of the probe body, etc., which will make the service life of the product longer than originally planned. The limit value is shorter, and frequent replacement of the handpiece will bring a large burden on the cost of consumables to the user, so it is urgent to introduce a cooling unit that can effectively cool the heat generated in the main body to extend the life of the cartridge

[0008] In addition, even if such a cooling unit is introduced, the exact surgical location cannot be confirmed in real time, which may lead to repeated operations, causing skin damage and burns
