The body 9a may be formed in one body, or the cover 93a may be coupled to the base body 92a. The outlet portion 941a and the portion 911a of the first through hole 91a may have a size enough to allow the wire pin to pass therethrough.
실린더(3a)는 그 길이방향으로 관통된 제2 관통구멍(31a)을 구비한다. 또한 레버(8a)의 상부(81a)가 위치할 수 있도록 그 상하방향으로 관통된 슬롯(32a)이 형성되어 있다. 이러한 실린더(3a)는 보디(9a)의 제1 관통구멍(91a) 내에서 이동 가능하게 장착된다.The cylinder 3a has a second through hole 31a penetrated in the longitudinal direction thereof. In addition, a slot 32a penetrated in the vertical direction is formed so that the upper portion 81a of the lever 8a can be positioned. This cylinder 3a is movably mounted in the first through hole 91a of the body 9a.
레버(8a)는 보디(9a)에 장착된 핀(95a)을 중심으로 보디(9a)에 회동 가능하게 장착되어 실린더(3a)를 보디(9a)에 대해 전후 방향(도 3 기준 좌우방향)으로 상대적으로 이동시킬 수 있다.The lever 8a is rotatably mounted to the body 9a around the pin 95a mounted on the body 9a so that the cylinder 3a can be moved forward and backward with respect to the body 9a in the front-rear direction (refer to Fig. 3 left and right directions). Can be moved relatively.
중앙 케이스(center case)(4a)는 실린더(3a)의 제2 관통구멍(31a) 내에 장착되고 실린더(3a)의 이동에 연동하여 이동되며 그 길이방향으로 제3 관통구멍(41a)을 구비한다. 중앙 케이스(4a)를 실린더(3a)에 연동하기 위해서, 도 3에 도시된 바와 같이, 예시적으로 중앙 케이스(4a)의 후방에서 그 외벽을 둘러싸도록 스냅 링(snap ring)(42a)을 고정하고, 전방에는 걸림턱(43a)을 형성하여 그 사이에 실린더(3a)를 배치할 수 있다. 이때, 실린더(3a)를 전,후방 격실로 구획한 후, 전방 격실(33a)에 제1 베어링(10a)을 배치하여 제1 베어링(10a)이 걸림턱(43a)에 접촉 지지되도록 구성할 수도 있다. 여기서, 제1 베어링(10a)은 실린더(3a)와 중앙 케이스(4a) 사이에 개재된다. 그리고 중앙 케이스(4a)의 선단 부분에는 내경이 점진적으로 확장된 콘 형상의 확장부(44a)가 형성된다. 이 확장부(44a)에는 후술하는 복수 개의 볼(52a)이 접촉한다.The center case 4a is mounted in the second through hole 31a of the cylinder 3a and moves in conjunction with the movement of the cylinder 3a and has a third through hole 41a in its longitudinal direction. . In order to interlock the center case 4a to the cylinder 3a, as illustrated in FIG. 3, a snap ring 42a is fixed to surround the outer wall at the rear of the center case 4a by way of example. In addition, the engaging jaw 43a may be formed in front and the cylinder 3a may be disposed therebetween. In this case, the cylinder 3a may be divided into front and rear compartments, and then the first bearing 10a may be disposed in the front compartment 33a so that the first bearing 10a is in contact with and supported by the locking jaw 43a. have. Here, the first bearing 10a is interposed between the cylinder 3a and the center case 4a. And the cone-shaped expansion part 44a by which the internal diameter gradually expanded is formed in the front-end | tip part of the center case 4a. The plurality of balls 52a to be described later are in contact with the expansion portion 44a.
삽입 케이스(insert case)(5a)는 전단 부분이 중앙 케이스(4a)의 전단 부분에서 후술하는 볼(52a)을 통하여 제3 관통구멍(41a)의 내벽에 접촉하고, 타단은 보디(9a)의 후단 방향으로 연장되어 있다. 즉, 삽입 케이스(5a)는 그 전단 부분의 외면에 복수 개의 볼(52a)이 원주 방향으로 소정의 간격을 두고 회동 가능하게 장착되어 있고, 복수 개의 볼(52a)은 중앙 케이스(4a)의 제3 관통구멍(41a)의 내벽에 접촉한다. In the insert case 5a, the front end portion contacts the inner wall of the third through hole 41a through the ball 52a described later in the front end portion of the central case 4a, and the other end of the body 9a It extends in the rear end direction. That is, the insertion case 5a is rotatably mounted on the outer surface of the front end part of the insertion case 5a at predetermined intervals in the circumferential direction, and the plurality of balls 52a are made of the center case 4a. 3 It contacts the inner wall of the through-hole 41a.
보디(9a)의 후단 부분에서 삽입 케이스(5a)의 외벽과 보디(9a)의 제1 관통구멍(91a)의 내벽 사이에 제2 베어링(11a)이 설치되는 것이 바람직하다.It is preferable that a second bearing 11a be provided between the outer wall of the insertion case 5a and the inner wall of the first through hole 91a of the body 9a at the rear end of the body 9a.
또한, 삽입 케이스(5a)는 그 길이방향으로 관통된 제5 관통구멍(51a)을 구비하며, 또한, 그 선단 부분에는 하나 이상의 슬릿(55a)이 길이 방향으로 형성되어, 중심방향으로 힘이 가해질 때 오무려들고 힘이 해제될 때는 원상 복귀한다.In addition, the insertion case 5a has a fifth through hole 51a penetrated in the longitudinal direction, and one or more slits 55a are formed in the longitudinal direction in the tip portion thereof, whereby a force is applied in the center direction. When it's frustrating and when the force is released, it returns to its original state.
또한, 삽입 케이스(5a)는 외벽에 홈(54a)이 형성되고, 이에 대응하여 중앙 케이스(4a)의 내벽에도 홈(미도시)이 형성되어, 이들 삽입 케이스(5a)의 홈(54a)과 중앙 케이스(4a)의 홈에 조인트 핀(53a)의 일부가 각각 걸치도록 삽입되어 있다. 이를 통하여 삽입 케이스(5a)의 회전시 중앙 케이스(4a)도 연동하게 회전하게 된다. 한편, 중앙 케이스(4a)가 삽입 케이스(5a)에 대하여 길이 방향으로 이동 가능하도록 중앙 케이스(4a)의 내벽에 형성된 홈은 그 길이가 조인트 핀(53a)보다는 길게 형성되어 있다. In addition, grooves 54a are formed in the outer wall of the insertion case 5a, and grooves (not shown) are also formed in the inner wall of the center case 4a so as to correspond to the grooves 54a of these insertion cases 5a. A part of the joint pin 53a is inserted in the groove of the center case 4a, respectively. As a result, when the insertion case 5a is rotated, the center case 4a is also rotated to interlock. On the other hand, the groove formed in the inner wall of the center case 4a is formed longer than the joint pin 53a so that the center case 4a can move in the longitudinal direction with respect to the insertion case 5a.
탄성부재(2a) 예컨대, 스프링이 보디(9a)의 제1 관통구멍(91a)의 내벽에 대해 실린더(3a)를 탄성적으로 지지한다. 구체적으로, 탄성부재(2a)는 일단이 제1 베어링(10a)에, 타단이 보디(9a)의 제1 관통구멍(91a)의 내벽에 지지될 수 있다.An elastic member 2a, for example, a spring elastically supports the cylinder 3a with respect to the inner wall of the first through hole 91a of the body 9a. Specifically, one end of the elastic member 2a may be supported by the first bearing 10a and the other end of the elastic member 2a by the inner wall of the first through hole 91a of the body 9a.
이하에서는 도 3 내지 도 5를 참조하여, 본 발명의 한 실시예에 따른 와이어 핀 홀딩용 의료기구의 작용에 대하여 설명한다.3 to 5, the operation of the wire pin holding medical device according to an embodiment of the present invention will be described.
도 5의 (a)는 레버(8a)에 A 방향으로 힘을 가한 상태(개방 상태)이고, 도 5의 (b)는 레버(8a)에 B 방향으로 힘을 가한 상태(폐쇄 상태)이다.FIG. 5A is a state in which a force is applied to the lever 8a in the A direction (open state), and FIG. 5B is a state in which a force is applied to the lever 8a in the B direction (closed state).
도 5에 도시되어 있는 바와 같이, 레버(8a)를 후방(B 방향)으로 잡아당기면, 레버(8a)는 핀(95a)을 중심으로 회동하게 된다. 이때, 레버(8a)의 상부(81a)가 실린더(3a)를 전방(도 5 기준 좌측 방향)으로 밀어주게 되고 제1 베어링(10a)은 탄성부재(2a)의 탄성력을 극복하면서 중앙 케이스(4a)의 걸림턱(43a)을 밀어주게 된다. 이를 통해 중앙 케이스(4a)가 삽입 케이스(5a)에 상대적으로 전방으로 이동하게 된다. 이러한 이동에 의하여, 볼(52a)과 접촉하고 있는, 중앙 케이스(4a)의 선단 부분의 확장부(44a)의 내경은 점진적으로 줄어들게 된다. 따라서, 중앙 케이스(4a)는 삽입 케이스(5a)의 일단에 장착된 볼(52a)을 직경 방향 내측으로 눌러주게 되며, 중앙 케이스(4a)의 일단은 오무려지게 된다. 최종적으로 삽입 케이스(5a)의 제5 관통구멍(51a)에 삽입된 와이어 핀(P)이 삽입 케이스(5a)의 선단 부분에 고정되게 된다.As shown in Fig. 5, when the lever 8a is pulled rearward (B direction), the lever 8a is rotated about the pin 95a. At this time, the upper portion 81a of the lever 8a pushes the cylinder 3a forward (left direction based on FIG. 5) and the first bearing 10a overcomes the elastic force of the elastic member 2a while the center case 4a. Push the locking jaw (43a) of the). Through this, the center case 4a is moved forward relative to the insertion case 5a. By this movement, the inner diameter of the extension portion 44a of the tip portion of the center case 4a, which is in contact with the ball 52a, gradually decreases. Therefore, the center case 4a presses the ball 52a mounted at one end of the insertion case 5a in the radially inward direction, and one end of the center case 4a is deflected. Finally, the wire pin P inserted into the fifth through hole 51a of the insertion case 5a is fixed to the tip portion of the insertion case 5a.
한편, 레버(8a)에 가해진 힘을 해제할 경우 탄성부재(2a)의 반발력에 의해 실린더(3a)는 후방으로 이동하고, 이에 연동하여 중앙 케이스(4a)도 후방으로 이동하면서 직경 방향 내측으로 볼(52a)에 가해진 힘이 해제되면서 삽입 케이스(5a)의 전단 부분은 다시 벌어지게 된다. 따라서, 삽입 케이스(5a)의 제5 관통구멍(51a)에 삽입된 와이어 핀(P)의 고정도 해제되게 된다.On the other hand, when releasing the force applied to the lever 8a, the cylinder 3a moves backward by the repulsive force of the elastic member 2a, and in conjunction with this, the center case 4a also moves backward, and the ball is moved inward in the radial direction. As the force applied to the 52a is released, the front end portion of the insertion case 5a is opened again. Therefore, the fixing of the wire pin P inserted into the 5th through hole 51a of the insertion case 5a is also released.
덧붙여, 도 6에 도시된 바와 같이, 본 와이어 핀 홀딩용 의료기구는 삽입 케이스(5a)의 타단에는 회전 전동 공구(100a)가 연결되어, 회전 전동 공구(100a)에 의해 발생하는 회전력에 의해 삽입 케이스(5a) 및 중앙 케이스(4a)는 보디(9a) 내에서 실린더(3a)에 대해 상대적으로 회전할 수 있다.In addition, as shown in FIG. 6, in the wire pin holding medical device, the rotary power tool 100a is connected to the other end of the insertion case 5a, and is inserted by the rotational force generated by the rotary power tool 100a. The case 5a and the center case 4a can rotate relative to the cylinder 3a in the body 9a.
