Description

수술부위 관찰이 가능한 레이저수술장치Laser Surgical Device for Surgical Site Observation

본 발명은 레이저빔을 발생시켜 치료병변을 수술하는 레이저수술장치에 관한 것으로, 특히 카메라가 부착된 핸드피스를 구성하여 확대된 영상으로 수술부위를 보면서 수술부위의 미세한 출혈까지도 정확하게 관찰이 가능한 레이저수술장치에 관한 것이다.The present invention relates to a laser surgery apparatus for treating a treatment lesion by generating a laser beam, and in particular, by configuring a handpiece with a camera, a laser surgery capable of observing even minute bleeding at the surgical site while viewing the surgical site with an enlarged image. Relates to a device.

도 1은 종래의 레이저수술장치를 나타낸 구성도이다. 레이저수술장치는 레이저빔을 발생하는 레이저빔 발생수단(10) 및 생성된 레이저빔을 수술부위로 전달하는 레이저빔 전달수단(20)으로 나눌 수 있다. 이 레이저빔 전달수단(20)은 도 2에 도시된 바와같이 핸드피스(handpiece)(30)가 부착되어 있으며, 이 핸드피스(30)는 레이저빔 발생수단(10)으로부터 출력되는 레이저빔을 수술부위까지 전달한다. 도 3은 도 2에 도시된 핸드피스(30)를 상세히 도시한 구성도이다. 핸드피스(30)는 연결나사(31)로 레이저빔 전달수단(20)과 연결되고, 레이저빔 집속렌즈(33)를 통해 집속된 레이저빔이 앤드팁(End-Tip)(35)으로 전달되어 수술부위에 직접 조사된다. 레이저빔 집속렌즈(33)와 앤드팁(34) 사이의 공기주입구(34)는 레이저가 피부조직에 조사될 때, 살갗이 타면서 나는 연기가 시술자의 시야를 가리거나 카메라의 렌즈를 가리게 되는 것을 방지하기 위해 외부에서 주입된 공기를 수술부위로 내뿜어 연기를 흐트러뜨리는 역할을 한다.1 is a block diagram showing a conventional laser surgery apparatus. The laser surgery apparatus may be divided into a laser beam generation means 10 for generating a laser beam and a laser beam delivery means 20 for delivering the generated laser beam to a surgical site. The laser beam delivery means 20 has a handpiece 30 attached thereto, as shown in FIG. 2, and the handpiece 30 operates the laser beam output from the laser beam generating means 10. Deliver to site. 3 is a block diagram showing in detail the handpiece 30 shown in FIG. The handpiece 30 is connected to the laser beam delivery means 20 by a connecting screw 31, and the laser beam focused through the laser beam focusing lens 33 is delivered to the end tip 35. Irradiated directly to the surgical site. The air inlet 34 between the laser beam focusing lens 33 and the end tip 34 indicates that when the laser is irradiated to the skin tissue, the burning smoke obscures the operator's field of view or the camera's lens. In order to prevent the air injected from the outside to blow out the acting role to distract the smoke.

종래에는 시술자(의사)가 상술한 바와같은 종래의 레이저수술장치를 사용하여 수술할 때, 육안으로 직접 수술부위를 관찰하면서 수술을 하였다. 그러므로, 미세한 부위의 정교한 수술 및 미세한 출혈의 감지가 불가능하였다. 또한, 수술부위와 정상부위의 경계를 육안으로 구별하는데는 한계가 있기 때문에 치료병변이외의 부위에도 레이저빔이 조사되는 문제점이 있었다.In the related art, when a surgeon (doctor) operates using a conventional laser surgery apparatus as described above, the surgeon performs surgery while observing the surgical site directly with the naked eye. Therefore, it was not possible to detect minute surgery and fine bleeding. In addition, since there is a limit in distinguishing the boundary between the surgical site and the normal site with the naked eye, there is a problem that the laser beam is irradiated to the areas other than the treatment lesion.

따라서, 본 발명의 목적은 레이저수술장치에 카메라를 부착하여 수술부위를 촬영함으로써 미세출혈의 관찰 및 정확한 치료병변에 레이저빔을 조사할 수 있는 수술부위 관찰이 가능한 레이저수술장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a laser surgery apparatus capable of observing a surgical site that can be irradiated with a laser beam on the observation of the microbleeding and accurate treatment lesion by attaching a camera to the laser surgery apparatus to photograph the surgical site.
