도 2에 도시된 바와 같이, 본 발명의 일 실시예에 따른 핸드 피스의 캡(100)은 상면부(110), 제1 측면부(120), 제2 측면부(130), 보강 플레이트(112), 열전도 플레이트(122) 및 복수의 주름 유도윙(131, 132, 133)을 포함한다. 본 발명의 일 실시예에 따른 핸드 피스의 캡(100)은 핸드 피스(20, 도 1 참고)의 하우징(21, 도 1 참고)에 교체 가능하게 결합될 수 있다.As shown in Figure 2, the cap 100 of the hand piece according to an embodiment of the present invention is the top surface 110, the first side portion 120, the second side portion 130, the reinforcing plate 112, It includes a heat conduction plate 122 and a plurality of wrinkle guide wings (131, 132, 133). The cap 100 of the hand piece according to an embodiment of the present invention may be interchangeably coupled to the housing 21 (see FIG. 1) of the hand piece 20 (see FIG. 1).
캡(100)은 상면부(110), 제1 측면부(120) 및 제2 측면부(130)에 의해 하방으로 개방되는 공간(23a, 도 5 참고)을 형성한다.The cap 100 forms a space 23a (refer to FIG. 5) opened downward by the upper surface portion 110, the first side portion 120, and the second side portion 130.
상면부(110)는 공간(23a)의 천정과 공간(23a)의 측면 중 상부 영역 일부를 형성할 수 있다. 도 2에 도시된 바와 같이, 상면부(110)의 상단은 단변 측이 라운드지게 형성되는 대략 직사각형의 형상으로 형성될 수 있다.The upper surface part 110 may form part of an upper region of the ceiling of the space 23a and the side surface of the space 23a. As shown in FIG. 2, the upper end of the upper surface portion 110 may be formed in a substantially rectangular shape in which the short side is rounded.
도 2 및 도 5에 도시된 바와 같이, 상면부(110)의 상단 일부에는 홈(111)이 형성되고, 홈(111)에는 보강 플레이트(112)가 결합된다. 보강 플레이트(112)는 상면부(110)의 강성을 강화하는 부재로서, 금속재와 같은 강성이 높은 재질로 구성될 수 있다.As shown in FIG. 2 and FIG. 5, a groove 111 is formed in a portion of the upper end portion 110, and a reinforcement plate 112 is coupled to the groove 111. The reinforcing plate 112 is a member for strengthening the rigidity of the upper surface portion 110 and may be made of a material having high rigidity such as a metal material.
도 2에 도시된 바와 같이, 보강 플레이트(112)에는 진공 유로(112a)가 형성된다. 진공 유로(112a)는 보강 플레이트(112) 및 상면부(110)를 관통하여 공간(23a)과 연결된다. 진공 유로(112a)는 공간(23a) 내부의 공기가 배출되는 유로가 된다.As shown in FIG. 2, a vacuum flow path 112a is formed in the reinforcing plate 112. The vacuum passage 112a penetrates the reinforcing plate 112 and the upper surface portion 110 and is connected to the space 23a. The vacuum flow path 112a is a flow path through which air in the space 23a is discharged.
한 쌍의 제1 측면부(120)는 상면부(110)의 장변측으로부터 하방으로 연장 형성된다. 따라서, 한 쌍의 제1 측면부(120)는 서로 마주보도록 형성되며 공간(23a)의 측면 중 일부를 형성한다.The pair of first side portions 120 extend downward from the long side of the upper surface portion 110. Thus, the pair of first side portions 120 are formed to face each other and form part of the side surfaces of the space 23a.
도 5에 도시된 바와 같이, 제1 측면부(120)의 일부에는 개구부(121)가 형성된다. 그리고 개구부(121)에는 열전도 플레이트(122)가 설치된다. 열전도 플레이트(122)는 핸드 피스(20, 도 1 참고)의 하우징(21, 도 1 참고)에 설치되어 있는 냉각 모듈(22, 도 1 참고)에 맞닿아 냉각 모듈(22)로부터 발생한 냉열을 공간(23a) 내로 전달한다.As shown in FIG. 5, an opening 121 is formed in a part of the first side part 120. The heat conduction plate 122 is installed in the opening 121. The heat conduction plate 122 abuts the cooling module 22 (see FIG. 1) installed in the housing 21 (see FIG. 1) of the hand piece 20 (see FIG. 1) to provide a space for cooling heat generated from the cooling module 22. To 23 (a).
동시에 열전도 플레이트(122)는 제1 측면부(120)의 강성을 강화하는 역할을 담당한다.At the same time, the heat conducting plate 122 plays a role of strengthening the rigidity of the first side portion 120.
도 5에 도시된 바와 같이, 열전도 플레이트(122)는 상단이 상면부(110)까지 연장되도록 L자 형상으로 절곡 형성되어, 공간(23a)의 천정 일부를 형성할 수 있다. 열전도 플레이트(122)의 상단이 공간(23a)의 천정 일부를 형성하도록 구성되어, 상면부(110)의 강성을 강화함과 동시에, 냉각 모듈(22)로부터 전달되는 냉열이 공간(23a)의 측면과 천정에서 동시에 공간(23a) 내부로 전달되도록 할 수 있다.As illustrated in FIG. 5, the heat conductive plate 122 may be bent into an L shape such that an upper end thereof extends to the upper surface portion 110, thereby forming a ceiling portion of the space 23a. The upper end of the heat conduction plate 122 is configured to form a part of the ceiling of the space 23a, and while the rigidity of the upper surface portion 110 is strengthened, the cooling heat transmitted from the cooling module 22 and the side of the space 23a It can be delivered to the inside of the space 23a at the same time from the ceiling.
도 5에 도시된 바와 같이, 한 쌍의 제1 측면부(120) 각각에 위치하는 열전도 플레이트(122)는 상면부(110)의 하부에서 일정 거리(G) 이격되도록 결합된다. 이는 각 열전도 플레이트(122)에 접하는 냉각 모듈(22)이 독립적으로 온도 조절되는 경우에 냉각 모듈(22)로부터 전달되는 서로 다른 온도의 냉열을 독립적으로 공간(23a) 내로 전달하기 위함이다.As shown in FIG. 5, the heat conduction plates 122 positioned at each of the pair of first side parts 120 are coupled to be spaced apart from each other by a predetermined distance G from the lower part of the upper surface part 110. This is to independently transfer the cold heat of different temperatures transmitted from the cooling module 22 into the space 23a when the cooling module 22 in contact with each heat conductive plate 122 is independently temperature controlled.
한편, 한 쌍의 제2 측면부(130)는 상면부(110)의 단변측으로부터 하방으로 연장 형성된다. 따라서, 한 쌍의 제2 측면부(130) 역시 서로 마주보도록 형성되며 공간(23a)의 측면 중 다른 일부를 형성한다.On the other hand, the pair of second side portion 130 is formed to extend downward from the short side of the upper surface portion (110). Therefore, the pair of second side parts 130 also face each other and form another part of the side surfaces of the space 23a.
한 쌍의 제1 측면부(120)와 한 쌍의 제2 측면부(130)의 하단은 폐루프를 형성하도록 연결되어 치료 부위에 접하게 된다.The lower ends of the pair of first side parts 120 and the pair of second side parts 130 are connected to form a closed loop to be in contact with the treatment site.
도 2에 도시된 바와 같이, 캡(100)에 외력이 작용하지 않는 “자유 상태”에서는 제2 측면부(130)의 하단이 제1 측면부(120)의 하단보다 아래에 위치하게 된다.As shown in FIG. 2, in the “free state” in which the external force does not act on the cap 100, the lower end of the second side part 130 is positioned below the lower end of the first side part 120.
제2 측면부(130)는 제1 측면부(120) 및 상면부(110)에 비해 가요성의 재질 또는 구조를 갖도록 형성된다. The second side portion 130 is formed to have a flexible material or structure compared to the first side portion 120 and the upper surface portion 110.
예를 들어, 제2 측면부(130)는 제1 측면부(120) 및 상면부(110)에 상대적으로 연성의 재질로 형성되어, 외력에 의해 제1 측면부(120) 및 상면부(110)에 비해 우선적으로 변형될 수 있다.For example, the second side portion 130 is formed of a soft material relatively to the first side portion 120 and the upper surface portion 110, compared to the first side portion 120 and the upper surface portion 110 by an external force. May be preferentially deformed.
또는, 제2 측면부(130)는 제1 측면부(120) 및 상면부(110)에 비해 얇은 두께로 형성되거나, 외력에 의해 탄성 변형되는 구조로 형성되어, 외력에 의해 제1 측면부(120) 및 상면부(110)에 비해 우선적으로 변형될 수 있다.Alternatively, the second side portion 130 is formed in a thickness thinner than the first side portion 120 and the upper surface portion 110, or is formed in a structure that is elastically deformed by an external force, the first side portion 120 and It may be preferentially deformed compared to the upper surface 110.
본 실시예에서는 제2 측면부(130)가 제1 측면부(120) 및 상면부(110)에 비해 얇은 두께로 형성되는 예를 기준으로 설명한다.In this embodiment, the second side portion 130 will be described with reference to an example in which the thickness is thinner than the first side portion 120 and the upper surface portion 110.
상면부(110), 제1 측면부(120) 및 제2 측면부(130)는 실리콘, 고무 등과 같은 재질로 형성될 수 있다. 특히 제1 측면부(120) 및 제2 측면부(130)는 치료 대상과 접하는 부분으로서 진공 유로(112a)를 통해 공간(23a) 내부가 음압 분위기로 형성된 상태에서 캡(100)의 외부에 대해 밀폐되어야 하므로, 실리콘, 고무 등과 같은 탄성력과 밀폐력이 우수한 재질로 형성되는 것이 바람직하다.The upper surface portion 110, the first side portion 120, and the second side portion 130 may be formed of a material such as silicon or rubber. In particular, the first side portion 120 and the second side portion 130 are portions in contact with the object to be treated to be sealed to the outside of the cap 100 in a state in which the inside of the space 23a is formed in a negative pressure atmosphere through the vacuum flow path 112a. Therefore, it is preferable to be formed of a material having excellent elasticity and sealing force, such as silicone, rubber, and the like.
다만, 상면부(110)와 제1 측면부(120)는 공간(23a) 내부가 음압 분위기로 형성된 상태에서도 형태를 유지하여야 하므로 제2 측면부(130)보다 두꺼운 두께를 갖도록 형성되는 것이 바람직하다. 또한, 제1 측면부(120)는 열전도 플레이트(122)에 의해 강성이 강화되고, 상면부(110)는 보강 플레이트(112) 및 열전도 플레이트(122)에 의해 강성이 강화된다. 따라서, 공간(23a) 내부가 음압 분위기인 상태에서 상면부(110)와 제1 측면부(120)는 현태를 온전하게 유지할 수 있다.However, the upper surface part 110 and the first side part 120 are preferably formed to have a thicker thickness than the second side part 130 because the inside of the space 23a must maintain its shape even in a negative pressure atmosphere. In addition, the first side portion 120 is strengthened by the heat conducting plate 122, the upper surface portion 110 is reinforced by the reinforcing plate 112 and the heat conducting plate 122. Therefore, the upper surface portion 110 and the first side surface portion 120 may maintain the current state in a state in which the inside of the space 23a is in a negative pressure atmosphere.
반면, 제2 측면부(130)는 상면부(110) 및 제1 측면부(120) 보다 얇은 두께로 형성되어, 캡(100)의 하단에서 상방으로 작용하는 외력에 의해 제1 측면부(120)의 하단과 제2 측면부(130)의 하단의 상대적인 높이가 변화하도록 제2 측면부(130)는 변형된다.On the other hand, the second side portion 130 is formed to a thickness thinner than the upper surface portion 110 and the first side portion 120, the lower end of the first side portion 120 by an external force acting upward from the lower end of the cap 100 The second side portion 130 is deformed so that the relative heights of the lower ends of the second side portion 130 are changed.
즉, 상면부(110)와 제1 측면부(120)는 캡(100)의 하단에서 상방으로 작용하는 외력에 의해 크게 변형되지 않는 반면, 제2 측면부(130)는 하단이 상승하며 변형된다.That is, the upper surface portion 110 and the first side portion 120 are not greatly deformed by the external force acting upward from the lower end of the cap 100, while the second side portion 130 is deformed with the lower end raised.
따라서, 캡(100)의 하단에서 상방으로 작용하는 외력에 의해 제1 측면부(120) 및 제2 측면부(130)의 하단에 형성하는 평균적인 곡률이 작아지게 된다.Therefore, the average curvature formed at the lower ends of the first side portion 120 and the second side portion 130 by the external force acting upward from the lower end of the cap 100 is reduced.
도 3에 도시된 바와 같이, 제2 측면부(130)는 제1 측면부(120)에 가까울수록 높이 낮아지도록 형성된다. 즉, 제2 측면부(130)는 캡(100)의 양측에서 가장 높이가 높고, 캡(100)의 내측으로 갈수록 높이가 낮아지도록 형성되어, 전체적으로 마름모가 캡(100)의 양측을 둘러싸는 형상을 갖는다.As shown in FIG. 3, the second side portion 130 is formed to be lower as the first side portion 120 gets closer. That is, the second side portion 130 is formed so that the height is the highest on both sides of the cap 100, the height is lowered toward the inner side of the cap 100, the rhombus as a whole surrounds both sides of the cap 100 Have
따라서, 제2 측면부(130)는 제1 측면부(120)와 가장 인접하는 C 지점을 중심으로 캡(100)의 양측 높이가 낮아지는 방식으로 변형된다. Accordingly, the second side portion 130 is deformed in such a manner that both sides of the cap 100 are lowered about the point C closest to the first side portion 120.
도 2 및 도 3에 도시된 바와 같이, 제2 측면부(130)의 외측에는 복수의 주름 유도윙(131, 132, 133)이 부착된다. 2 and 3, a plurality of wrinkle guide wings 131, 132, and 133 are attached to the outside of the second side portion 130.
각각의 주름 유도윙(131, 132, 133)은 제2 측면부(130)의 외측을 가로 방향으로 지지하며, 복수의 주름 유도윙(131, 132, 133)은 수직 방향으로 적층 배치된다. Each of the pleat guide wings (131, 132, 133) supports the outer side of the second side portion 130 in the horizontal direction, the plurality of pleat guide wings (131, 132, 133) are stacked in a vertical direction.
따라서, 제2 측면부(130)가 캡(100)의 하단에서 상방으로 작용하는 외력에 의해 변형되는 과정에서, 주름 유도윙(131, 132, 133)은 제2 측면부(130)가 주름을 형성하며 변형되도록 유도한다. 즉, 캡(100)의 하단에서 상방으로 작용하는 외력에 의해 제2 측면부(130)가 변형되는 “변형 상태”에서 주름 유도윙(131, 132, 133)이 부착된 부분에서 주름이 형성되며, 반복적인 변형에도 제2 측면부(130)가 항상 일정한 “변형 상태”를 유도한다.Therefore, in the process of the second side portion 130 is deformed by the external force acting upward from the lower end of the cap 100, the pleat guide wings (131, 132, 133) is the second side portion 130 to form a wrinkle Induce to deform. That is, the wrinkles are formed at the portion where the pleat guide wings 131, 132, and 133 are attached in the “deformed state” in which the second side portion 130 is deformed by an external force acting upward from the lower end of the cap 100, Even with repeated deformation, the second side portion 130 always induces a constant “deformation state”.
도 4에 도시된 바와 같이, 복수의 주름 유도윙(131, 132, 133)은 가상의 직선에서 상호 교차하는 서로 다른 평면(P1, P2, P3) 상에 위치할 수 있다. 그리고 각 평면(P1, P2, P3)이 교차하는 가상의 직선은 C 지점을 통과하도록 형성될 수 있다. 따라서, “변형 상태”에서 제2 측면부(130)에 형성되는 복수의 주름은 가상의 직선으로부터 연장되는 형상을 가질 수 있다.As shown in FIG. 4, the plurality of wrinkle guide wings 131, 132, and 133 may be located on different planes P 1 , P 2 , and P 3 that cross each other in an imaginary straight line. An imaginary straight line intersecting each plane P 1 , P 2 , P 3 may be formed to pass through point C. Therefore, the plurality of wrinkles formed in the second side portion 130 in the “deformed state” may have a shape extending from an imaginary straight line.
본 실시예에 따른 캡(100)은 양측에 각각 3개의 주름 유도윙(131, 132, 133)을 포함한다. 설명의 편의를 위해, 3개의 주름 유도윙(131, 132, 133)은 아래로부터 제1 주름 유도윙(131), 제2 주름 유도윙(132), 제3 주름 유도윙(133)으로 지칭한다.The cap 100 according to the present embodiment includes three pleated guide wings 131, 132, and 133 on both sides, respectively. For convenience of description, the three wrinkle guide wings 131, 132, 133 are referred to as a first wrinkle guide wing 131, a second wrinkle guide wing 132, and a third wrinkle guide wing 133 from below. .
중앙에 위치하는 제2 주름 유도윙(131, 132, 133)은 도 4의 지면(紙面)에 수직하게 C 지점을 통과하는 가상의 직선을 포함하는 제2 평면(P2) 상에 위치한다. 실시예에 따라, “자유 상태”에서 제2 평면(P2)은 수평면이 될 수 있다.The second wrinkle guide wings (131, 132, 133) located in the center is located on the second plane (P 2 ) including an imaginary straight line passing through point C perpendicular to the ground of FIG. According to an embodiment, in the “free state” the second plane P 2 may be a horizontal plane.
