본 발명은 레이저 장비의 암 끝단에 장착구성하여 사용하는 레이저치료기용 핸드피스에 관한 것이다.The present invention relates to a handpiece for a laser therapy device to be used mounted to the arm end of the laser equipment.

보다 상세하게는 핸드피스를 사용하여 레이저 치료를 하는 과정에서 핸드피스 내부로 유입되는 연기나 먼지 등을 비롯한 각종 불순물의 유입을 사전에 차단하여 레이저 빔이 항상 안정적이면서 균일하게 조사될 수 있게 하고, 이에 따라 레이저 빔의 효율을 높임과 동시에 신뢰성을 극대화시킬 수 있게 하기 위한 것이다. In more detail, the laser beam is always stably and uniformly irradiated by blocking the inflow of various impurities such as smoke or dust introduced into the handpiece during laser treatment using the handpiece in advance. Accordingly, to increase the efficiency of the laser beam and at the same time maximize the reliability.

주지된 바와 같이 종래 레이저 장비에 사용되는 암은 크게 두가지 방식이 있 는데, 하나는 외장형 암이고, 다른 하나는 내장형 암이다.As is well known, the arms used in conventional laser equipment are largely divided into two types, one is an external arm and the other is an internal arm.

외장형 암은 하단에 핸드피스를 연결하여 에어를 외부에서 공급하여 주는 방식으로 핸드피스 외부에 연결구와 바람을 공급하는 실리콘 및 고무호스 선이 노출되어 있게 되어 사용시 불편하고 오염이 되는 경우가 많이 발생하며, 에어를 차단하고자 할 때는 레이저 장비에 전기 전자적으로 회로를 구성하여 작동하므로 불편한 점들이 매우 많이 발생한다.The external arm connects the handpiece to the bottom to supply air from the outside, so the silicone and rubber hose wires that supply the connector and the wind are exposed to the outside of the handpiece, which causes inconvenience and contamination. In order to block the air, the circuit is electrically and electronically operated in the laser equipment, which causes a lot of inconveniences.

그러나 상기한 외장형 암은 핸드피스내부에는 오염이 발생하지 않는 이점이 있다.However, the external arm has an advantage that contamination does not occur inside the handpiece.

내장형 암은 호스이 오염은 없으나 에어를 차단하면 시술시 발생하는 연기가 핸드피스를 통해 암의 내부로 유입되게 되에 암 내부의 반사경이 연기에 오염되어 반사율이 급격히 떨어져 레이저 위치를 지시하는 지시빔이 보이지 않게 되므로 시술이 어려워지는 현상이 발생하게 된다. The built-in arm has no contamination with the hose, but if the air is blocked, the smoke generated during the procedure is introduced into the arm through the handpiece.The reflector inside the arm is contaminated with the smoke and the reflectance drops sharply, indicating the laser position. Since it becomes invisible, the procedure becomes difficult.

따라서 본 발명은 전술한 레이저치료용 장비의 암 중에서 내장형 암에 적용되는 핸드피스를 구성함에 있어서, 핸드피스의 끝단부분 즉, 아암에 연결되는 연결관체에 에어를 배출할 수 있는 장공을 형성함과 동시에 상기 에어를 배출하는 장공을 개폐시킬 수 있게끔 구성함으로서 핸드피스의 조사관을 통하여 에어를 불어내고자 할 때는 상기 장공을 닫고, 그 외에는 상기 장공을 개방시켜 암을 통해 공급되는 에어가 장공을 통하여 외부로 배출되게 함으로서 시술중에 암 내부에 연기가 차거나 이물질이 끼어 레이저 위치를 지시하는 빔이 잘 보이지 않게 되는 등의 폐단 을 사전에 예방할 수 있게 하려는 데 발명의 목적이 있는 것이다.Therefore, the present invention is to form a long hole for discharging air to the end of the handpiece, that is, the connecting body connected to the arm in configuring the handpiece applied to the built-in arm of the arm of the laser treatment equipment described above and At the same time, it is configured to open and close the air outlet for discharging the air to close the long hole when blowing air through the irradiation tube of the handpiece, otherwise open the long hole to open the air supplied through the arm through the long hole The purpose of the present invention is to prevent the lungs from being smoked or foreign matters caught during the procedure, such that the beam indicating the laser position is difficult to see.
