Description

Power connection structure of the skin return pad

[0001] The present invention relates to a power connection structure of a skin return pad, and is an invention relating to a power connection structure of a skin return pad capable of detecting a state in which a return pad in contact with the skin in a monopolar type skin RF energy generating device is completely connected to a connection terminal for connection to a control body.

[0002] RF energy generators, which are generally used for skin beauty purposes, are devices that heat the skin and underlying tissues using RF electrodes (radio frequency).

[0003] RF energy generators are used for skin recovery by raising the temperature of the skin after cryolipolysis treatment by contacting the RF electrode with the skin and delivering RF energy to the skin, and for skin treatment that heats the skin and underlying tissues to cause collagen contraction or induce a wound healing response.

[0004] Recently, with the increasing interest in skin beauty, bipolar RF energy generators are being used in various ways, such as skin remodeling / resurfacing through contraction or wound healing of collagen in the lower dermis, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins.

[0005] RF energy generators are mainly used in the monopolar type, which has one electrode in contact with the skin, and the bipolar type, which has two electrodes in contact with the skin.

[0006] A bipolar RF energy generator uses a pair of RF electrodes that come into contact with the skin. One RF electrode becomes the (+) electrode, and the other becomes the (-) electrode. RF energy emitted from the (+) electrode, that is, high-frequency energy, flows into the (-) electrode, transmitting RF energy into the skin.

[0007] In addition, the monopolar RF energy generator is composed of a handpiece in which an RF tip having an RF electrode part is detachably connected, a control body that is connected to the handpiece via a control cable to control the operation of the handpiece, and a return pad that is connected to the control body via a power supply cable and is used as a grounding electrode by being in contact with the patient's skin at a distance from the RF electrode part.

[0008] The monopolar method has the characteristic of transmitting RF energy to the dermis layer of the skin by moving the RF energy generated from the RF electrode part in contact with the skin to the return pad attached on the other side, which allows for a deeper penetration depth of RF energy compared to the bipolar method.

[0009] In addition, the return pad is usually manufactured and used as a disposable device, and is detachably connected to an integrated clip terminal provided at the end of a power supply cable and is then attached to the patient's skin for use in the procedure.

[0010] The return pad includes an adhesive pad portion that is attached to the patient's skin and two power connection terminal portions that protrude from one side of the adhesive pad portion. The two power connection terminal portions are arranged in parallel and inserted into the interior of the integrated clip terminal portion and connected to the clip terminal.

[0011] If the power connection terminal of the return pad is unstable, not only will the treatment effect be reduced, but there is also a problem of burns occurring on the skin that comes into contact with the return pad.

[0012] The power connection terminal part is partially inserted into the interior of the integrated clip terminal part, and the remaining part is exposed to the exterior of the integrated clip terminal part and comes into contact with the patient's skin.

[0013] In addition, there was a problem that if the connection status of the power connection terminal was unstable, burns frequently occurred on the skin in the part of the power connection terminal that came into contact with the skin during the procedure.

[0014] The purpose of the present invention is to provide a power connection structure of a skin return pad that checks whether the power connection terminal of the return pad is normally connected when the power connection terminal of the return pad is connected to the pad connection terminal of the control body.

[0015] In order to achieve the above object, one embodiment of a power connection structure of a skin return pad according to the present invention is characterized by including a control main body for controlling the operation of an RF energy generating unit having an RF electrode unit that contacts the skin and transmits RF energy into the skin, a return pad unit electrically connected to the control main body, contacts the skin at a position spaced apart from the RF electrode unit and has a power connection terminal unit on one side, a pad connection unit positioned at an end side of a power cable connected to the control main body and having a pad connection terminal that is detachably connected to the power connection terminal unit, and a terminal connection confirmation unit for confirming whether the pad connection terminal and the power connection terminal unit are normally connected.

[0020] In the present invention, the pad connection portion may further include a terminal pressing portion positioned on the upper surface of the connection casing portion to pressurize the first upper connection terminal and the second upper connection terminal to connect them to the power connection terminal portion.

[0021] In the present invention, the terminal pressing portion may include a connecting rotary panel portion that is rotatably hinged to the upper portion of the connecting casing portion, a first terminal pressing protrusion that protrudes from the lower side of the connecting rotary panel portion and presses the first upper connecting terminal, and a second terminal pressing protrusion that protrudes from the lower side of the connecting rotary panel portion and is spaced apart from the first terminal pressing protrusion and presses the second upper connecting terminal.

[0059] FIG. 1 is a schematic diagram illustrating one embodiment of a skin RF energy generating device including a power connection structure of a skin return pad according to the present invention, FIG. 2 is a perspective view illustrating one embodiment of a power connection structure of a skin return pad according to the present invention, and FIG. 3 is a cross-sectional view illustrating one embodiment of a power connection structure of a skin return pad according to the present invention.

[0060] Referring to FIGS. 1 to 3, one embodiment of a power connection structure of a skin return pad according to the present invention and one embodiment of a skin RF energy generating device including the same are described in detail below.

[0061] One embodiment of a skin RF energy generator according to the present invention includes an RF energy generator (110) having an RF electrode (110a) that contacts the skin and transmits RF energy into the skin, a control body (100) that is connected to the RF energy generator (110) by a control cable (112a) and supplies electric power to the RF electrode (110a) of the RF energy generator (110) and controls its operation, and a return pad (200) that contacts the skin of a patient, is positioned apart from the RF electrode (110a), and is electrically connected to the control body (100).

[0062] The return pad part (200) comes into contact with the skin at a location spaced apart from the RF electrode part (110a) and is provided with a power connection terminal part (200b) on one side for electrical connection to the control body part (100).

[0063] The return pad part (200) is an electrode that comes into contact with the skin at a location spaced apart from the RF electrode part (110a) and has a polarity different from that of the RF electrode part (110a) and serves as a ground electrode.

[0066] The RF energy generating unit (110) is equipped with an RF electrode unit (110a) that transmits RF energy into the skin, and can be variously modified into a known RF energy generating handpiece that the practitioner holds and uses by hand, so a more detailed description is omitted.

[0067] The control body (100) includes an RF signal generation unit that generates RF energy by applying electric power to the RF electrode unit (110a), and can be implemented in various ways with a known configuration in a known RF energy generation device for skin treatment, so a more detailed description thereof is omitted.

[0068] The return pad part (200) includes a pad electrode part (200a) attached to the skin at a position spaced apart from the RF electrode part (110a) and a power connection terminal part (200b) positioned to protrude from one side of the pad electrode part (200a) and electrically connected to the control body part (100).

[0069] In addition, the return pad portion (200) further includes a film portion (200c) for electrode attachment, to which a pad electrode portion (200a) is attached, and which has an attachment margin area that is attached to the skin along the outer periphery of the pad electrode portion (200a).

[0070] The entire pad electrode portion (200a) and a portion of the power connection terminal portion (200b) are attached and fixed to the electrode attachment film portion (200c), and the remaining portion of the power connection terminal portion (200b) is provided to protrude from one side of the electrode attachment film portion (200c).

[0071] The pad electrode portion (200a) and the power connection terminal portion (200b) are manufactured from a conductive sheet that can be bent freely, and are manufactured from a known material used to manufacture a return pad, so a more detailed description thereof will be omitted.

[0072] One embodiment of the power connection structure of the skin return pad according to the present invention further includes a pad connection portion (300) located at the end side of a power cable (113) connected to the control main body portion (100) and connected to a power connection terminal portion (200b) of the return pad portion (200).

[0073] The pad connection part (300) is provided with a connection casing part (310) having a terminal opening through which a power connection terminal part (200b) passes on one side, and a pad connection terminal (320) that is positioned inside the connection casing part (310) and connected to the power connection terminal part (200b) inserted inside.

[0074] The terminal (320) for pad connection is connected to the control unit in the control body and the power cable (113), and the control unit includes a terminal connection confirmation unit (400).

[0075] The terminal connection confirmation unit (400) is, for example, connected to the pad connection terminal (320) by a power cable (113) and includes an impedance detection unit (450) that detects the impedance detected by the pad connection terminal (320) to check whether the pad connection terminal (320) and the power connection terminal (200b) are normally connected.

[0076] The pad connection terminal (320) includes a first connection terminal (320a) and a second connection terminal (320b) that are positioned spaced apart from each other inside the connection casing portion (310) and are connected to the power connection terminal portion (200b), and the impedance detection portion (450) is electrically connected to the first connection terminal (320a) and the second connection terminal (320b) to detect the impedance of the first connection terminal (320a) and the second connection terminal (320b), thereby checking whether the power connection terminal portion (200b) is normally connected to the first connection terminal (320a) and the second connection terminal (320b), as an example.

[0077] In more detail, the first connection terminal (320a) and the second connection terminal (320b) are positioned apart from the entrance of the connection casing part (310), i.e., the terminal opening part, in the insertion direction of the power connection terminal part (200b) and are connected to the power connection terminal part (200b).

[0078] The power connection terminal part (200b) is formed to have a length that can be inserted into the interior of the connection casing part (310) and connected to the first connection terminal (320a) and the second connection terminal (320b), and is formed to have a length that can be left outside the connection casing part (310) while being inserted into the interior of the connection casing part (310) and connected to the first connection terminal (320a) and the second connection terminal (320b) that are spaced apart from each other.

[0079] The first connection terminal (320a) includes a first lower connection terminal (321) located on the lower side within the connection casing (310) and connected to the lower surface of the power connection terminal portion (200b), and a first upper connection terminal (322) located on the upper side within the connection casing (310) and forming a terminal passage through which the power connection terminal portion (200b) passes between the first lower connection terminal (321) and the first upper connection terminal (322) and connected to the upper surface of the power connection terminal portion (200b).

[0080] The second connection terminal (320b) includes a second lower connection terminal (323) located on the lower side within the connection casing (310) and connected to the lower surface of the power connection terminal portion (200b), a second upper connection terminal (324) located on the upper side within the connection casing (310) and forming a terminal inlet through which the power connection terminal portion (200b) passes between the second lower connection terminal (323) and the upper surface of the power connection terminal portion (200b), and a connection terminal (325) connecting the other end side of the second lower connection terminal (323) and the other end side of the second upper connection terminal (324).

[0081] The connecting terminal (325) connects the other end of the second lower connecting terminal (323) and the other end of the second upper connecting terminal (324), thereby blocking the space between the second lower connecting terminal (323) and the second upper connecting terminal (324) and serving as a stopper to limit the insertion length of the power connecting terminal (200b).

[0082] In addition, the connecting terminal (325) elastically connects the second lower connecting terminal (323) and the second upper connecting terminal (324) to support a gap that allows the power connection terminal portion (200b) to be smoothly inserted between the second lower connecting terminal (323) and the second upper connecting terminal (324), and when the second upper connecting terminal (324) is pressed to connect the power connection terminal portion (200b) between the second lower connecting terminal (323) and the second upper connecting terminal (324), and then the pressing force is released, the second upper connecting terminal (324) can be returned to its original position.

[0083] The first connection terminal (320a) is separated from the first lower connection terminal (321) and the first upper connection terminal (322), so that the entire portion of the first lower connection terminal (321) and the entire portion of the second upper connection terminal (324) are spaced apart, thereby forming a terminal passage through which the power connection terminal portion (200b) passes in the insertion direction of the power connection terminal portion (200b), thereby allowing the power connection terminal portion (200b) to be inserted to the position of the second connection terminal (320b).

[0084] In addition, the second connection terminal (320b) has a structure in which the open portion of the terminal is positioned toward the terminal opening in the shape of the letter D (D-shaped) including the second lower connection terminal (323), the second upper connection terminal (324), and the connection terminal (325), thereby elastically supporting the second upper connection terminal (324) with the connection terminal (325) and blocking the space between the second lower connection terminal (323) and the second upper connection terminal (324) to limit the insertion length of the power connection terminal portion (200b).

[0085] The pad connection part (300) further includes a terminal pressure part (330) located on the upper surface of the connection casing part (310) to pressurize the first upper connection terminal (322) and the second upper connection terminal (324) to connect them to the power connection terminal part (200b).

[0086] The terminal pressurizing portion (330) presses the other end of the first upper connecting terminal (322) having elasticity to press and connect the power connection terminal portion (200b) with the first upper connecting terminal (322), and presses the second upper connecting terminal (324) elastically supported by the connecting terminal (325) to press and connect the power connection terminal portion (200b) with the second upper connecting terminal (324).

[0087] The terminal pressurizing portion (330) includes a connecting rotary panel portion (331) that is rotatably hinged to the upper portion of the connecting casing portion (310), a first terminal pressurizing protrusion (332) that protrudes from the lower side of the connecting rotary panel portion (331) to pressurize the first upper connecting terminal (322), and a second terminal pressurizing protrusion (333) that protrudes from the lower side of the connecting rotary panel portion (331) at a distance from the first terminal pressurizing protrusion (332) to pressurize the second upper connecting terminal (324).

[0088] The terminal pressurizing portion (330) is hinged so that one end of the connecting rotary panel portion (331) is rotatably connected to the upper part of the connecting casing portion (310) and presses the other end of the connecting rotary panel portion (331) to press the first connecting terminal (320a) and the second connecting terminal (320b) from the upper side with the first terminal pressurizing protrusion (332) and the second terminal pressurizing protrusion (333), thereby connecting the power connection terminal portion (200b) to the first connecting terminal (320a) and the second connecting terminal (320b) between the first upper connecting terminal (322) and the first lower connecting terminal (321) and between the second upper connecting terminal (324) and the second lower connecting terminal (323).

[0089] The upper portion of the connection casing (310) is provided with an open portion through which a first terminal pressurizing protrusion (332) and a second terminal pressurizing protrusion (333) can be inserted inside.

[0090] And, when the terminal pressurizing part (330) is lifted while the power connection terminal part (200b) is pressed between the first lower connection terminal (321) and between the second upper connection terminal (324) and the second lower connection terminal (323) and connected to the first connection terminal (320a) and the second connection terminal (320b), the elastic restoring force of the first upper connection terminal (322) and the elastic restoring force of the connection terminal (325) cause a separation between the first upper connection terminal (322) and the power connection terminal part (200b), and a separation between the second upper connection terminal (324) and the power connection terminal part (200b).

[0091] The return pad part (200) includes a first return pad sheet (210) including a first pad electrode part (211) attached to the skin and a first power connection terminal part (212) positioned so as to protrude from one side of the first pad electrode part (211) and electrically connected to the control body part (100), and a second return pad sheet including a second pad electrode part (221) attached to the skin and spaced apart from the first return pad sheet (210) and a second power connection terminal part (222) positioned so as to protrude from one side of the second pad electrode part (221) and electrically connected to the control body part (100).

[0092] The first return pad sheet (210) and the second return pad sheet are each attached to the electrode film portion, and the first power connection terminal portion (212) and the second power connection terminal portion (222) are arranged parallel to each other in the same direction and positioned to protrude to one side of the electrode film portion, as an example.

[0093] In addition, the terminal (320) for pad connection includes a first connection terminal (320a) and a second connection terminal (320b) connected to the first power connection terminal section (212), a third connection terminal (320c) and a fourth connection terminal (320d) connected to the second power connection terminal section (222).

[0094] As an example, the first connection terminal (320a) and the third connection terminal (320c) each have a terminal structure including a first upper connection terminal (322) and a first lower connection terminal (321), and the second connection terminal (320b) and the fourth connection terminal (320d) each have a terminal structure including a second upper connection terminal (324), a second lower connection terminal (323), and a connection terminal (325).

[0095] And, the first connection terminal (320a), the second connection terminal (320b), the third connection terminal (320c), and the fourth connection terminal (320d) are electrically connected to the terminal connection confirmation unit (400).

[0096] The first terminal pressing projection (332) of the terminal pressing portion (330) has a shape that can simultaneously press the first upper connection terminal (322) of the first connection terminal (320a) and the third connection terminal (320c), and the second terminal pressing projection (333) of the terminal pressing portion (330) has a shape that can simultaneously press the second upper connection terminal (324) of the second connection terminal (320b) and the fourth connection terminal (320d).

[0097] Before the procedure, the power connection terminal part (200b) of the return pad part (200), that is, the first power connection terminal part (212) and the second power connection terminal part (222), are inserted into the interior of the connection casing part (310) through the terminal opening, and then the connection rotary panel part (331) is pressed, so that the first terminal pressing protrusion part (332) simultaneously presses the first upper connection terminal (322) of the first connection terminal (320a) and the third connection terminal (320c), and the second terminal pressing protrusion part (333) simultaneously presses the second upper connection terminal (324) of the second connection terminal (320b) and the fourth connection terminal (320d), thereby connecting the power connection terminal part (200b) to the pad connection terminal.

[0098] The terminal connection confirmation unit (400) confirms whether the first power connection terminal unit (212) is normally connected to the first connection terminal (320a) and the second connection terminal (320b) by checking the impedance values ​​detected at the first connection terminal (320a), the second connection terminal (320b), the third connection terminal (320c), and the fourth connection terminal (320d), and confirms whether the second power connection terminal unit (222) is normally connected to the third connection terminal (320c) and the fourth connection terminal (320d).

[0099] In addition, the terminal connection confirmation unit (400) includes a connection status notification unit that notifies whether the power connection terminal unit (200b) is normally connected to the pad connection terminal (320) or not normally connected.

[0100] The connection status notification unit notifies the operator through the control unit (100) or a warning sound when the power connection terminal (200b) is not normally connected to the pad connection terminal (320), or notifies the operator through the display unit of the control unit (100), for example.

[0101] In addition to this, the connection status notification can be implemented in various ways using other notification means such as warning lamps.

[0102] The connection status notification unit notifies the operator when the pad connection terminal (320) and the power connection terminal (200b) are not properly connected, so that the procedure can be performed only when the pad connection terminal (320) and the power connection terminal (200b) are properly connected.

[0103]

[0104] One embodiment of the RF energy generator for skin according to the present invention is a device that inserts the power connection terminal part (200b) of the return pad part (200), that is, the first power connection terminal part (212) and the second power connection terminal part (222) into the interior of the connection casing part (310) through the terminal opening, and then presses the connection rotation panel part (331) to connect the first power connection terminal part (212) to the first connection terminal (320a) and the second connection terminal (320b), respectively, and connects the fourth power connection terminal part (200b) to the third connection terminal (320c) and the fourth connection terminal (320d), and then attaches the return pad part to the patient's skin, and applies an operating signal from the control body part (100) while the RF electrode part (110a) of the RF energy generator part (110) is in contact with the patient's skin, thereby causing the RF energy generated on the skin to be in contact with the patient's skin. By transmitting RF energy to the skin through the electrode part (110a), the dermis within the skin is heated to treat the skin or induce a cosmetic effect.

[0105] If the connection rotary panel part (331) is not pressed down enough or the first power connection terminal part (212) and the second power connection terminal part (222) are inserted into the connection casing part (310) too short, the first power connection terminal part (212) may not be properly connected to the first connection terminal (320a) and the second connection terminal (320b), and the second power connection terminal part (222) may not be properly connected to the third connection terminal (320c) and the fourth connection terminal (320d).

[0106] One embodiment of the RF energy generator for skin according to the present invention checks whether the pad connection terminal (320) and the power connection terminal (200b) are normally connected by a terminal connection confirmation unit (400) before the procedure, and notifies the practitioner of this, so that the procedure can be performed only when the pad connection terminal (320) and the power connection terminal (200b) are normally connected.

[0107]

[0108] FIG. 4 is a schematic diagram illustrating an example of a terminal connection confirmation unit (400) in a power connection structure of a skin return pad according to the present invention, and is a schematic diagram illustrating an embodiment of a circuit structure of the terminal connection confirmation unit (400).

[0109] Referring to FIG. 4, the terminal connection confirmation unit (400) includes a first terminal connection portion (410) that electrically connects the first connection terminal (320a) and the second connection terminal (320b) and has a first resistor (411) positioned therein, a second terminal connection portion (420) that electrically connects the second connection terminal (320b) and the fourth connection terminal (320d) and has a second resistor (412) positioned therein, a third terminal connection portion (430) that electrically connects the third connection terminal (320c) and the fourth connection terminal (320d) and has a third resistor (413) positioned therein, a fourth terminal connection portion (440) that electrically connects the first connection terminal (320a) and the third connection terminal (320c) and has a fourth resistor (414) positioned therein, a first connection terminal (320a) or It includes an impedance detection unit (450) that is electrically connected to the second connection terminal (320b) and electrically connected to the third connection terminal (320c) or the fourth connection terminal (320d) to detect a resistance value.

[0110] The normal resistance values ​​are preset when the first power connection terminal (212) is normally connected to the first connection terminal (320a) and the second connection terminal (320b), respectively, and the second power connection terminal (222) is normally connected to the third connection terminal (320c) and the fourth connection terminal (320d), respectively, by the first resistance value, the second resistance value, the third resistance value, and the fourth resistance value.

[0111] Accordingly, the impedance detection unit (450) inserts the power connection terminal portion (200b) of the return pad portion (200) before the procedure, that is, the first power connection terminal portion (212) and the second power connection terminal portion (222), into the interior of the connection casing portion (310) through the terminal opening portion, and then presses the connection rotation panel portion (331) to check the resistance values ​​by the first resistor (411), the second resistor (412), the third resistor (413) and the fourth resistor (414) to check whether the checked resistance values ​​are normal resistance values, thereby checking whether the connection is normal.

[0112] For example, when the first resistor (411), the second resistor (412), the third resistor (413), and the fourth resistor (414) all have the same resistance value, the first power connection terminal (212) is normally connected to the first connection terminal (320a) and the second connection terminal (320b), and the second power connection terminal (222) is normally connected to the third connection terminal (320c) and the fourth connection terminal (320d), the normal resistance value detected by the impedance detection unit (450) is 0.

[0113] The impedance detection unit (450) verifies that the pad connection terminal (320) and the power connection terminal (200b) are normally connected when the detected resistance value is 0, and if the resistance value is not 0, it verifies that the pad connection terminal (320) and the power connection terminal (200b) are not normally connected and notifies the operator of the connection status through the connection status notification unit.

[0114]

[0115] FIG. 5 is a schematic diagram showing another example of a terminal connection confirmation unit (400) in a power connection structure of a skin return pad according to the present invention, and the terminal connection confirmation unit (400) may include an impedance detection unit (450) located in the control body (100) and electrically connected to the first connection terminal (320a), the second connection terminal (320b), the third connection terminal (320c), and the fourth connection terminal (320d), respectively, to confirm the impedance value detected at the first connection terminal (320a), the second connection terminal (320b), the third connection terminal (320c), and the fourth connection terminal (320d).

[0116] As an example, the impedance detection unit (450) is electrically connected to the first connection terminal (320a), the second connection terminal (320b), the third connection terminal (320c), and the fourth connection terminal (320d) via the first wire, the second wire, the third wire, and the fourth wire, respectively.

[0117] The impedance detection unit (450) presets a normal impedance value when the first power connection terminal (212) is normally connected to the first connection terminal (320a) and the second connection terminal (320b), and the second power connection terminal (222) is normally connected to the third connection terminal (320c) and the fourth connection terminal (320d).

[0118] Accordingly, the impedance detection unit (450) inserts the power connection terminal portion (200b) of the return pad portion (200) before the procedure, that is, the first power connection terminal portion (212) and the second power connection terminal portion (222), into the interior of the connection casing portion (310) through the terminal opening portion, and then presses the connection rotation panel portion (331), and checks the impedance value while attaching the return pad portion (200) to the skin to check whether the connection is normal.

[0119] And, if the impedance detection unit (450) detects that the pad connection terminal (320) and the power connection terminal (200b) are normally connected when the detected impedance value is a normal impedance value, and if the impedance value is not a normal impedance value, it detects that the pad connection terminal (320) and the power connection terminal (200b) are not normally connected and notifies the operator of this through the connection status notification unit.

[0120]

[0121] The present invention prevents an accident in which a burn occurs on the patient's skin due to a short circuit of the return pad during a procedure by checking whether the power connection terminal (200b) of the return pad (200) is normally connected when the power connection terminal (200b) of the return pad (200) is connected to the pad connection terminal (320) of the control body (100), and enables stable and efficient procedure.
