Abstract: A surgical instrument for irradiating a focused ultrasound includes a main body, a driving unit which is provided in the main body to generate arbitrary rotational force, a support plate which is fixed into the main body by forming a spiral guide groove on any one surface and allows one side of the driving unit to penetrate to be supported, a traction unit which is coupled to one penetrating side of the driving unit to rotate in response to the rotational force generated in the driving unit and is movably coupled to the guide groove of the support plate to be pulled to draw a spiral path along the guide groove during the rotation, and a following unit which is coupled to one side of the traction unit to output a focused ultrasound while following the traction motion of the traction unit.

Abstract: According to an exemplary embodiment, a structure of a surgical instrument for irradiating a focused ultrasound wave at a plurality of depths includes a movement unit, one pair of frames, a first transducer assembly which horizontally moves by the movement unit and upwardly/downwardly vertically moves to irradiate a focused ultrasound wave at a plurality of depths, a fitting unit which is coupled with the first transducer assembly, and a housing which accommodates the first transducer assembly in an inner space and is coupled to the movement unit to horizontally move the first transducer assembly in one direction or in the other direction by the movement unit or horizontally reciprocates the first transducer assembly in one direction and the other direction.

Abstract: Embodiments relate to a high-frequency application method for improving collagen production and tissue improvement function in a skin, and to a skin beauty device using the same, and more specifically, to a high-frequency application method for improving collagen production and tissue improvement function in a skin, and to a skin beauty device using the same, which may induce new collagen production in the skin and improve a basement membrane tissue by cross-and-sequentially applying a monopolar type pulsed high frequency and a bipolar type pulsed high frequency, thereby improving the skin, including the effect of reducing freckles, and increasing skin elasticity and obtaining a lifting effect.

Abstract: According to an exemplary embodiment, a structure of a surgical device for irradiating focused ultrasound to multiple depths includes: a motor equipped with a rotating shaft; a ball screw rotating by power of the motor, having a first external screw thread engraved on an outer side, and having an accommodation groove formed in a longitudinal direction on a portion of the outer side; and a ball nut having an internal screw thread engraved on an inner side that meshes with the first external screw thread when the ball screw is penetrated, and moving linearly by following the rotation of the ball screw.

Abstract: An air conditioner and a method of operating an air conditioner are provided. The air conditioner may include a heat pump having a water-refrigerant heat exchanger that condenses or evaporates a refrigerant by heat exchange with heat source water; a heat source water flow path connected to the water-refrigerant heat exchanger; a pump installed on the heat source water flow path; a variable flow valve installed on the heat source water flow path; and a variable flow valve controller that controls an opening degree of the variable flow valve. The variable flow valve controller may include a heat source water minimum flow manipulator that manipulates a minimum flow rate of the heat source water and regulates the opening degree of the variable flow valve according to the manipulation of the heat source water minimum flow manipulator. Accordingly, a user or installation personnel may selectively regulate power consumption and efficiency as desired.
