압박패드(150)는 디텍터(140)에 놓인 유방을 압박한다. 압박패드(150)는 제너레이터(130)와 디텍터(140) 사이에 위치한다. 그리고 유방의 압박과 압박 해제를 위해, 압박패드(150)는 제너레이터(130)와 디텍터(140) 사이를 직선 이동한다. The compression pad 150 compresses the breast placed on the detector 140. The compression pad 150 is positioned between the generator 130 and the detector 140. In addition, the compression pad 150 moves linearly between the generator 130 and the detector 140 to press and release the breast.
이동장치(160)는 도2에서와 같이 C 암(120)의 내부 수용 공간에 설치된다. 이동장치(160)는 압박패드(150)를 디텍터(140)로부터 멀거나 가깝게 이동시킨다. The moving device 160 is installed in the inner receiving space of the C arm 120 as shown in FIG. The moving device 160 moves the compression pad 150 away from or close to the detector 140.
도3은 이동장치(160)가 포함된 주요 부분에 대한 사시도이고, 도4는 주요 부분에 대한 분해 사시도이다. 이동장치(160)는 구동모터(161), 구동풀리(162a), 피동풀리(162b), 구동벨트(163), 구동축(164), 제1 풀리(165a), 제2 풀리(165b), 전환벨트(166) 및 결합부재(167)를 포함한다. 3 is a perspective view of the main part including the moving device 160, Figure 4 is an exploded perspective view of the main part. The moving device 160 includes a drive motor 161, a drive pulley 162a, a driven pulley 162b, a drive belt 163, a drive shaft 164, a first pulley 165a, a second pulley 165b, and a changeover. And a belt 166 and a coupling member 167.
구동모터(161)는 압박패드(150)를 이동시키는 구동력을 제공하는 구동원으로서 구비된다. The drive motor 161 is provided as a drive source for providing a driving force for moving the pressing pad 150.
구동풀리(162a)는 구동모터(161)의 작동에 따라 회전한다. The drive pulley 162a rotates according to the operation of the drive motor 161.
피동풀리(162b)는 구동축(164)의 일단에 결합된다. The driven pulley 162b is coupled to one end of the drive shaft 164.
구동벨트(163)는 구동풀리(162a)와 피동풀리(162b)를 회전 반환점으로 하여 회전한다. The drive belt 163 rotates by using the drive pulley 162a and the driven pulley 162b as a rotation return point.
구동축(164)은 일 단이 피동풀리(162b)에 결합되고 타 단이 베어링(B)에 의해 지지된다. One end of the drive shaft 164 is coupled to the driven pulley 162b and the other end is supported by the bearing B.
따라서 구동모터(161)가 작동하면 구동풀리(162a), 피동풀리(162b) 및 구동축(164)이 연동하여 회전한다. Therefore, when the driving motor 161 operates, the driving pulley 162a, driven pulley 162b, and the driving shaft 164 rotate in conjunction with each other.
제1 풀리(165a)는 클러치(170)의 작동에 따라 구동축(164)과 선택적으로 연동하여 회전한다. 즉, 제1 풀리(165a)와 구동축(164)은 서로 연동하여 회전하거나 연동이 해제된다. The first pulley 165a rotates selectively with the driving shaft 164 according to the operation of the clutch 170. That is, the first pulley 165a and the drive shaft 164 rotate or interlock with each other in cooperation with each other.
제2 풀리(165b)는 압박패드(150)의 직선 이동 방향(D)으로 제1 풀리(165a)와 이격되게 위치한다. The second pulley 165b is positioned to be spaced apart from the first pulley 165a in the linear movement direction D of the pressing pad 150.
전환벨트(166)는 제1 풀리(165a)와 제2 풀리(165b)를 회전 반환점으로 하여 회전한다. The changeover belt 166 rotates using the first pulley 165a and the second pulley 165b as the rotation return points.
여기서 제1 풀리(165a), 제2 풀리(165b) 및 전환벨트(166)는 구동축(164)의 회전에 따라 압박패드(150)를 직선 이동시키는 이동기로서 작용한다. Here, the first pulley 165a, the second pulley 165b, and the switching belt 166 serve as a mover for linearly moving the pressing pad 150 according to the rotation of the drive shaft 164.
결합부재(167)는 일 측이 전환벨트(166)에 결합되고 타 측이 압박패드(150)에 결합된다. 따라서 전환벨트(166)가 회전하면 결합부재(167)와 압박패드(150)가 직선 이동한다. Coupling member 167 is one side is coupled to the conversion belt 166 and the other side is coupled to the pressure pad 150. Therefore, when the conversion belt 166 rotates, the coupling member 167 and the pressure pad 150 move linearly.
클러치(170)는 제1 풀리(165a)를 구동축(164)의 회전에 선택적으로 속박시킨다. 이를 위해 클러치(170)는 제1 플랜지(171) 및 제2 플랜지(172)를 포함한다. The clutch 170 selectively binds the first pulley 165a to the rotation of the drive shaft 164. To this end, the clutch 170 includes a first flange 171 and a second flange 172.
제1 플랜지(171)는 구동축(164)에 관통 결합되어서 구동축(164)과 함께 회전한다. 이러한 제1 플랜지(171)는 전원 공급에 의해 자력을 발생시키는 전자석을 내장한다. The first flange 171 is coupled to the drive shaft 164 to rotate together with the drive shaft 164. The first flange 171 has a built-in electromagnet that generates a magnetic force by the power supply.
제2 플랜지(172)는 제1 플랜지(171)에 자력 결합한다. 이를 위해 제2 플랜지(172)는 자성체이거나 자성체를 가진다. 그리고 제2 플랜지(172)는 제1 풀리(165a)와 결합된다. 따라서 제1 플랜지(171)와 제2 플랜지(172)의 자력 결합에 의해 제1 풀리(165a)가 구동축(164)의 회전에 속박된다. The second flange 172 magnetically couples to the first flange 171. To this end, the second flange 172 is magnetic or has magnetic material. The second flange 172 is coupled to the first pulley 165a. Accordingly, the first pulley 165a is bound to the rotation of the drive shaft 164 by the magnetic coupling of the first flange 171 and the second flange 172.
물론, 제2 플랜지가 전자석이고 제1 플랜지가 자성체일 수 있다. Of course, the second flange may be an electromagnet and the first flange may be a magnetic material.
여기서 클러치(170)는 이동장치(160)의 일 구성으로 설명될 수도 있다. Here, the clutch 170 may be described as one configuration of the moving device 160.
도5는 제2 플랜지(172)가 제1 플랜지(171)에 자력 결합한 상태의 단면도이다. 5 is a cross-sectional view of a state in which the second flange 172 is magnetically coupled to the first flange 171.
도5와 같은 상태에서 구동모터(161)의 구동력은 구동풀리(162a), 구동벨트(163), 피동풀리(162b), 구동축(164), 제1 플랜지(171), 제2 플랜지(172), 제1 풀리(165a), 전환벨트(166), 결합부재(167)를 순차적으로 거쳐 압박패드(150)로 전달된다. 따라서 구동모터(161)의 정역 작동에 따라 압박패드(150)는 제너레이터(130)와 디텍터(140) 사이를 정역 직선 이동한다. In the state shown in FIG. 5, the driving force of the driving motor 161 is the driving pulley 162a, the driving belt 163, the driven pulley 162b, the driving shaft 164, the first flange 171, and the second flange 172. The first pulley 165a, the conversion belt 166, and the coupling member 167 are sequentially transmitted to the pressure pad 150. Accordingly, the press pad 150 moves forward and backward between the generator 130 and the detector 140 according to the forward and reverse operation of the driving motor 161.
만약 관리자에 의해 의도되거나 정전 등의 비상 상태로 인하여 제1 플랜지(171)로의 전원 공급이 차단되면 제1 플랜지(171)의 자력이 소멸된다. 이에 따라 과장된 도6에서와 같이 제2 플랜지(172)가 제1 플랜지(171)로부터 분리된다. 즉, 클러치(170)는 정전 같은 비상 상태에서 압박부재(150)와 이동장치(160) 간의 구동 연결을 자동으로 해제하는 해제장치로서도 작용한다. If the power supply to the first flange 171 is interrupted by an administrator or due to an emergency such as a power failure, the magnetic force of the first flange 171 is dissipated. Accordingly, the second flange 172 is separated from the first flange 171 as shown in FIG. 6, which is exaggerated. That is, the clutch 170 also acts as a release device for automatically releasing the drive connection between the pressing member 150 and the moving device 160 in an emergency state such as a power failure.
도6과 같은 상태에서는 제1 풀리(171)가 구동축(164)의 현재 상태로부터 자유로워진다. 이에 따라 압박패드(150)에 의한 유방의 압박 상태도 해제된다. 이를 위해 구동축(164)의 일 측 부분은 제1 플랜지(171)에 결합되지만, 구동축(164)의 타 측 부분은 제2 플랜지(172)와 제1 풀리(165a)를 유격 있게 관통하는 구조를 가진다. In the state as shown in FIG. 6, the first pulley 171 is freed from the current state of the drive shaft 164. Accordingly, the pressure state of the breast by the pressure pad 150 is also released. To this end, one side portion of the drive shaft 164 is coupled to the first flange 171, but the other side portion of the drive shaft 164 has a structure that penetrates the second flange 172 and the first pulley 165a freely. Have
참고로 제1 플랜지(171)와 제2 플랜지(172)를 자력으로 결합시키는 것은 유방에 과도한 압박을 가하지 않기 위함이다. For reference, the magnetic coupling of the first flange 171 and the second flange 172 is to avoid excessive pressure on the breast.
또한, 위의 실시예에서는 디텍터(140)로 유방을 지지하지만, 디텍터와는 별도의 검사판으로 유방을 지지하도록 구현할 수도 있다. In addition, in the above embodiment, the breast is supported by the detector 140, but may be implemented to support the breast by a test plate separate from the detector.
참고로, 동력의 정확한 전달을 위해 구동벨트(163) 및 전환벨트(166)는 타이밍벨트로 구비되는 것이 바람직하다. 그리고 구동풀리(162a), 피동풀리(162b), 제1 풀리(165a) 및 제2 풀리(165b)도 타이밍풀리로 구비되는 것이 바람직하다. For reference, the driving belt 163 and the switching belt 166 is preferably provided as a timing belt for accurate transmission of power. In addition, the driving pulley 162a, the driven pulley 162b, the first pulley 165a and the second pulley 165b are also preferably provided as timing pulleys.
<제2 실시예>Second Embodiment
도7은 본 발명의 제2 실시예에 따른 맘모그래피의 주요 부분에 대한 단면도이다. 7 is a cross sectional view of an essential part of a mammography according to a second embodiment of the present invention;
본 발명의 제2 실시예에 따른 맘모그래피도 이동장치(760)와 클러치(770)를 포함한다. The mammography according to the second embodiment of the present invention also includes a moving device 760 and a clutch 770.
이동장치(760)는 구동모터(761), 구동풀리(762a), 피동풀리(762b), 구동벨트(763), 구동축(764a), 제1 풀리(765a), 제2 풀리(765b), 전환벨트(766), 피동축(764b) 및 결합부재(767)를 포함한다. The moving device 760 includes a drive motor 761, a drive pulley 762a, a driven pulley 762b, a drive belt 763, a drive shaft 764a, a first pulley 765a, a second pulley 765b, and a changeover. A belt 766, driven shaft 764b, and coupling member 767 are included.
구동축(764a)은 구동풀리(762a), 피동풀리(762b) 및 구동벨트(763)와 연동한다. 이를 위해 피동풀리(762b)는 구동축(764a)에 관통 결합된다.  The drive shaft 764a is interlocked with the drive pulley 762a, driven pulley 762b, and the drive belt 763. To this end, the driven pulley 762b is coupled to the driving shaft 764a through.
피동축(764b)은 제1 풀리(765a), 제2 풀리(765b) 및 전환벨트(766)와 연동한다. 이를 위해 제1 풀리(765a)는 피동축(764b)에 관통 결합된다. The driven shaft 764b interlocks with the first pulley 765a, the second pulley 765b, and the switching belt 766. To this end, the first pulley 765a is coupled to the driven shaft 764b through.
결합부재(767)는 일 측이 전환벨트(766)와 결합되고 타 측이 압박패드와 결합된다.  Coupling member 767 is one side is coupled to the conversion belt 766 and the other side is coupled to the pressure pad.
클러치(770)는 피동축(764b)을 구동축(764a)의 회전에 속박시킨다. 이를 위해 클러치(770)는 구동축(764a)과 연동하는 제1 플랜지(771)와 피동축(764b)과 연동하는 제2 플랜지(772)를 포함한다. 제1 플랜지(771)는 구동축(764a)에 관통 결합되고, 제2 플랜지(772)는 제1 풀리(765a)와 결합되어 피동축(764b)에 관통 결합된다.  The clutch 770 binds the driven shaft 764b to the rotation of the drive shaft 764a. To this end, the clutch 770 includes a first flange 771 that cooperates with the drive shaft 764a and a second flange 772 that cooperates with the driven shaft 764b. The first flange 771 is penetrated and coupled to the drive shaft 764a, and the second flange 772 is coupled to the first pulley 765a and penetrated to the driven shaft 764b.
제1 플랜지(771)는 전원이 공급(ON)되면 자력을 발생시킨다. 그래서 전원이 공급되면 제1 플랜지(771)의 자력에 의해 제2 플랜지(772)가 제1 플랜지(771)에 결합된다. 따라서 제2 플랜지(772)가 제1 플랜지(771)의 회전에 연동하여 회전한다. 그리고 제2 플랜지(772)와 연동하는 피동축(764b) 및 제1 풀리(765a)도 회전하고, 압박패드는 승강한다. The first flange 771 generates a magnetic force when the power is supplied (ON). Thus, when power is supplied, the second flange 772 is coupled to the first flange 771 by the magnetic force of the first flange 771. Therefore, the second flange 772 rotates in conjunction with the rotation of the first flange 771. The driven shaft 764b and the first pulley 765a that interlock with the second flange 772 also rotate, and the pressure pad moves up and down.
물론 전원이 차단되면 제1 플랜지(771)의 자력은 소멸된다. 그리고 제2 플랜지(772)는 제1 플랜지(771)로부터 분리된다. 이로 인해 압박부재에 의해 환자의 유방에 가해지던 압박상태가 자동으로 해제된다.  Of course, when the power is cut off, the magnetic force of the first flange 771 is dissipated. And the second flange 772 is separated from the first flange 771. As a result, the pressing state applied to the breast of the patient by the pressing member is automatically released.
이상의 설명은 본 발명의 일 실시예에 대한 것이다. 따라서 본 발명은 예시한 실시예에 한정되는 것은 아니다. 본 발명은 청구범위 및 그 등가개념으로 이해되어야 한다. The above description is about one embodiment of the present invention. Therefore, the present invention is not limited to the illustrated embodiment. The invention should be understood with the claims and their equivalents.
