Abstract
Description
本發明係與內視鏡有關，特別是關於一種內視鏡之照明裝置。The present invention relates to endoscopes, and more particularly to an illumination device for an endoscope.
習知內視鏡之結構主要係於一主套筒內設有一位於該主套筒前端之鏡頭、一設於該鏡頭外圍且向前發光之照明裝置、一設於該鏡頭後方之影像感測器(例如電荷耦合裝置，Charge Coupled Device，簡稱CCD)，以及一控制電路；藉此，該內視鏡可用以探視鏡頭前方之畫面。當該內視鏡需用以探視鏡頭側方之畫面時，該主套筒之前端會再設置一配件套筒，該配件套筒具有一側開口，且該配件套筒內設有一反射鏡，該反射鏡可將該照明裝置發出之光線自該側開口反射出去，同時該側開口外之畫面可透過該反射鏡反射至該鏡頭。The structure of the conventional endoscope is mainly provided in a main sleeve with a lens at the front end of the main sleeve, an illumination device disposed on the periphery of the lens and emitting light forward, and an image sensing disposed behind the lens. A device (for example, a Charge Coupled Device, CCD for short), and a control circuit; thereby, the endoscope can be used to view a picture in front of the lens. When the endoscope needs to be used to view the side of the lens, the front end of the main sleeve is further provided with a fitting sleeve having a side opening, and a mirror is arranged in the fitting sleeve. The mirror can reflect the light emitted by the illumination device from the side opening, and the picture outside the side opening can be reflected to the lens through the mirror.
換言之，習用之內視鏡的照明裝置本身僅能向前照射，側向照射係透過反射鏡而達成。然而，若該反射鏡之鍍膜品質不佳，或者鏡面有髒污時，光線反射後會產生明顯散射，導致該內視鏡擷取到之畫面畫質不佳。因此，習用之內視鏡的照明裝置仍有其不足之處，而有待改進。In other words, the illumination device of the conventional endoscope itself can only be irradiated forward, and the lateral illumination is achieved by the mirror. However, if the coating quality of the mirror is not good, or the mirror surface is dirty, the light will reflect significantly after being reflected, resulting in poor image quality of the image taken by the endoscope. Therefore, the illumination device of the conventional endoscope still has its insufficiency and needs to be improved.
有鑑於上述缺失，本發明之主要目的在於提供一種內視鏡之照明裝置，不需透過鏡面反射即可供應內視鏡前向及側向探視時所需之光源，因此可使該內視鏡擷取到之畫面具有較佳之畫質。In view of the above-mentioned deficiencies, the main object of the present invention is to provide an illumination device for an endoscope, which can supply a light source required for forward and side view of the endoscope without specular reflection, thereby enabling the endoscope The captured image has a better picture quality.
為達成上述目的，本發明所提供之內視鏡之照明裝置，包含有一電路板單元，以及設於該電路板單元之至少一前發光件及至少一側發光件，該前發光件係用以朝向該內視鏡之一前方發光，該側發光件係用以朝向該內視鏡之一側方發光。藉此，當該內視鏡要探視鏡頭前方之畫面時，可利用該前發光件發光提供所需之光源；當該內視鏡要探視鏡頭側方之畫面而設置一具有反射鏡之配件套筒時，可利用該側發光件發光照射該鏡頭透過該反射鏡而探視之取像範圍處。如此一來，該照明裝置不需透過鏡面反射即可供應內視鏡前向及側向探視時所需之光源，因此可使該內視鏡擷取到之畫面具有較佳之畫質。In order to achieve the above object, an illumination device for an endoscope according to the present invention includes a circuit board unit, and at least one front light-emitting member and at least one light-emitting member disposed on the circuit board unit, wherein the front light-emitting member is used for Illuminating toward the front of one of the endoscopes, the side illuminating member is configured to emit light toward one side of the endoscope. Thereby, when the endoscope is to view the picture in front of the lens, the front illuminator can be used to illuminate to provide a desired light source; when the endoscope is to view the side of the lens, a set of accessories with a mirror is provided. In the case of the cylinder, the side illuminating member can be used to illuminate the image capturing range of the lens through the mirror. In this way, the illumination device can supply the light source required for the forward and side view of the endoscope without specular reflection, so that the image captured by the endoscope can have better image quality.

該內視鏡10更包含有一前套筒11及一後套筒12，該前套筒11內自前端到後端依序設置有一鏡頭13、一影像感測器14，以及一控制電路15。該前套筒11具有一前開口112及一側開口114，當該內視鏡10用以探視鏡頭13側方之畫面時，如第三圖所示，該前套筒11之前段會再套設一配件套筒17，該配件套筒17係不遮蔽該前套筒11之側開口114，且該配件套筒17具有一與該側開口114朝向相同方向之側視孔172，以及一與該側視孔172相對且位於該鏡頭13前方之反射鏡174。The endoscope 10 further includes a front sleeve 11 and a rear sleeve 12. The front sleeve 11 is provided with a lens 13, an image sensor 14, and a control circuit 15 from the front end to the rear end. The front sleeve 11 has a front opening 112 and a side opening 114. When the endoscope 10 is used to view the side of the lens 13, as shown in the third figure, the front sleeve 11 is re-sleeved. An accessory sleeve 17 is provided, the accessory sleeve 17 does not shield the side opening 114 of the front sleeve 11, and the fitting sleeve 17 has a side view hole 172 facing the same direction as the side opening 114, and a The side view aperture 172 is opposite the mirror 174 in front of the lens 13.
該電路板單元30為一軟性電路板，包含有相互一體連接之一呈半圓環形的第一區段31及一呈長條形的第二區段32，該電路板單元30係於該第一及第二區段31、32之交界處被彎折90度，而形成分別位於該第一及第二區段31、32之一前安裝面34及一側安裝面36，且該前安裝面34及該側安裝面36具有一呈直角之夾角。該等發光件40、50分別為一發光二極體，其中，各該前發光件40係設於該前安裝面34，該側發光件50係設於該側安裝面36。如第三圖所示，該前發光件40之光軸42及該側發光件50之光軸52係分別垂直於該前安裝面34及該側安裝面36，因此，該側發光件50之光軸52與各該前發光件40之光軸42具有一呈直角之夾角。The circuit board unit 30 is a flexible circuit board including a first section 31 which is semicircularly connected to each other and a second section 32 which is elongated, and the circuit board unit 30 is attached to the first And the junction of the second sections 31, 32 is bent 90 degrees to form a front mounting surface 34 and a side mounting surface 36 respectively of the first and second sections 31, 32, and the front mounting surface 34 and the side mounting surface 36 have an angle that is at a right angle. Each of the illuminating members 40 and 50 is a light emitting diode, wherein each of the front illuminating members 40 is disposed on the front mounting surface 34 , and the side illuminating member 50 is disposed on the side mounting surface 36 . As shown in the third figure, the optical axis 42 of the front illuminating member 40 and the optical axis 52 of the side illuminating member 50 are perpendicular to the front mounting surface 34 and the side mounting surface 36, respectively. The optical axis 52 has an angle with a right angle of the optical axis 42 of each of the front illuminators 40.
該電路板單元30係以該第一區段31設於該鏡頭13外圍，並以該第二區段32末端之一固定部322電性連接地固定於該控制電路15，因而該控制電路15可選擇性地使各該發光件40、50發光。當使用者要透過該內視鏡10探視鏡頭13前方之畫面時，藉由該控制電路15使該等前發光件40發光，即可提供所需之光源。當使用者在鏡頭13前方設置該配件套筒17，進而要透過該內視鏡10探視該側視孔172外的畫面時，藉由該控制電路15改使該側發光件50發光，該側發光件50之照射範圍可涵蓋到該側視孔172外至少一特定距離之處，同時該處之畫面可透過該反射鏡174反射到該鏡頭13。換言之，該照明裝置20不論是前向或側向照射，都是直接照射，而非透過鏡面反射，因此可使該內視鏡10擷取到之畫面具有較佳之畫質。The circuit board unit 30 is disposed on the periphery of the lens 13 with the first segment 31, and is fixedly connected to the control circuit 15 by a fixing portion 322 at one end of the second segment 32.
