도 2에는 도 1에 있는 노즐부(1)의 상세도를, 도 3에는 다른 분사각을 갖는 노즐부(1)의 다른 실시예를, 그리고 도 4에는 도 2에서의 노즐 본체(14)의 우측면도를 도시하였다.Fig. 2 shows a detailed view of the nozzle unit 1 shown in Fig. 1, Fig. 3 shows another embodiment of the nozzle unit 1 having a different spraying angle, and Fig. 4 shows the nozzle unit 14 And a right side view is shown.
우선 물관(22)으로 물이 유입되면 물관 연결부(18)에 의해 물관과 연결되어 있는 노즐 본체(14)내로 물이 유입되고, 유입된 물은 노즐 본체(14)의 일단이 막혀 있으므로 노즐 본체(14)에 있는 관통공(A)으로만 물이 배출되게 된다. 관통공(A)로 배출된 물은 노즐 본체(14)와 노즐 덮개(10) 사이의 미세한 틈(C)을 통과하여 노즐 덮개(10)의 분사공(B)을 통해 물이 분사되게 된다. 도 4에 도시된 바와 같이 노즐 본체(14)의 일단의 외면(30)에는 와선형 홈(E)이 다수 형성되어 있는 데, 이것은 물을 와류시켜 분사효과를 향상시키기 위한 것이다. 따라서, 본 발명에서는 에어를 사용하지 않고도 물을 효과적으로 분사시킬 수 있게 된다. 또한, 레이저 파이버 길이 조절부(2)는 레이저 파이버(24)의 길이를 조절하기 위한 것인 데, 정상 상태에서는 스프링(28)에 의하여 레이저 파이버 가이드관(25)이 눌려지면서 레이저 파이버(24)가 고정되고 길이 조절봉(26)이 눌려지면 레이저 파이버(24)가 움직일 수 있게 되어 그 길이를 조절할 수 있도록 되어 있다. 또한, 노즐 본체(14)의 말단의 각도(θ)는 120°로 되어 있어 유량이 적으면서도 분사가 잘되어 냉각효과가 향상되도록 하였다. 또한, 물관 연결부(18)를 이용하여 노즐부(1)를 레이저 핸드피스 본체(20)로부터 탈착시키고, 도 3에 도시된 바와 같은 분사각도가 다른 노즐부를 장착시키면, 시술부위에 따라 위치를 변화시켜 시술할 수 있다.When water is introduced into the water pipe 22, water flows into the nozzle body 14 connected to the water pipe by the water pipe connection part 18 and the inflow water is blocked at one end of the nozzle body 14, The water is discharged only through the through-hole (A) in the discharge port (14). The water discharged through the through hole A passes through the minute gap C between the nozzle body 14 and the nozzle lid 10 and water is sprayed through the spray hole B of the nozzle lid 10. As shown in FIG. 4, a plurality of vortex-shaped grooves E are formed on the outer surface 30 of one end of the nozzle body 14 for improving the jetting effect by swirling the water. Therefore, in the present invention, water can be effectively sprayed without using air. The laser fiber length adjuster 2 is for adjusting the length of the laser fiber 24. In a normal state, the laser fiber guide tube 25 is pressed by the spring 28, The length of the laser beam 24 can be adjusted and the length of the laser beam 24 can be adjusted. In addition, the angle? Of the distal end of the nozzle body 14 was set to 120 °, so that the injection efficiency was improved with a small flow rate, thereby improving the cooling effect. When the nozzle part 1 is detached from the laser handpiece body 20 by using the water pipe connection part 18 and a nozzle part having a different injection angle as shown in Fig. 3 is mounted, the position is changed according to the part to be treated .
이상 설명된 바와 같이 본 발명에 의한 향상된 스프레이 기능을 갖는 레이저 핸드피스는 노즐형 스프레이 장치를 사용하여 에어를 사용해야 하는 불편없이 수압만을 이용하여 스프레이 유량이 적으면서도 스프레이 기능이 향상되어 냉각효과가 큰 이점이 있다.As described above, the laser handpiece having the improved spray function according to the present invention is advantageous in that the spray function is improved while the spray flow rate is reduced by using only the water pressure without using the air by using the nozzle type spray device, .
