Description

內視鏡攝像鏡頭裝置改良
本創作為一種內視鏡攝像鏡頭裝置改良，主要在鏡頭部的側方開設以透光孔，而以內部發光體之光線經由透光片向外散射，達到增加整體的亮度，另將鏡頭部前端相對於前方發光體的位置設為霧面部，以使正向光源的透光均勻化，避免光線直射。
習知內視鏡的發光技術，最早是利用玻璃纖維進行導光作用，將導管後方的光源傳送到前端，以提供鏡頭攝像所需的照明功能，惟該材料在施作加工時容易斷裂，故有製造上的難度，且在應用時如有斷裂的情況發生，其斷裂之纖維對人體有一定的傷害，又不易清除，故並不實用。目前已知的改良鏡頭發光之構造，如圖一所示，主體為一圓柱形鏡頭部(1)，主要係在前端設置正向的數個發光體(11)，呈環狀排列，而攝像模組(12)係設在其中間位置，該發光體(11)通常為發光二極體，該設計在使用上，由於發光體(11)為正向發光，然而內視鏡之使用常係應用在含液體之器官腔內攝像，由於腔內具光滑面和充滿液體，容易和發光體射的光線形成直角，而產生反光現象，反應在攝像影像時，形成光點而成為視線盲點，致使於手術執行時，增加相當程度的風險性，另外，由於該設計的光源係集中在前端，在手術進行中，有產生高溫過熱的危險，故有待改良。
本創作為一種內視鏡攝像鏡頭裝置改良，主要在鏡頭部的側方開設以透光孔，並組合以透光片，而在鏡頭部的內部加設以縱向的發光體，使其光線得以經由透光片向外散射，達到增加整體的亮度，以供照亮人體之腔內部位，而利於拍攝取得更為清晰的影像；另外，在鏡頭部前端相對於前方發光體的位置，設為霧面部，使正向光源的透光均勻化，而能避免直射光導致強反光，使攝像影像產生光點之缺憾，獲致進步性者。

圖二為本創作內視鏡攝像鏡頭裝置改良構造圖
請參閱圖二所示，本創作為一種內視鏡攝像鏡頭裝置改良，主體為一圓柱形的鏡頭部(2)，其特徵在於鏡頭部(2)的兩側方分別開設以對稱的透光孔(21)，並於透光孔(21)位置組合以透光片(22)，而在鏡頭部(2)的內部加設以數個縱向的發光體(23)，例如為發光二極體，分別朝向透光孔(21)的方向設置，另在鏡頭部(2)前端相對於前方環狀設置之發光體(24)的位置，設為霧面部(25)，可利用霧面膠直接塗佈於上而成。因此，當本創作於使用時，各縱向發光體(23)發光時，其光線經由透光片(22)而得以向外散射，達到增加整體的亮度，以供手術時可以輔助照亮人體之腔內部位，而利於攝像模組(26)在拍攝獲得更充足的亮度，而取得更為清晰的影像；再者，由於正向光源可經由霧面部(25)的柔化作用，使正向光源的透光均勻化，而能避免直射光所可能導致的強反光，避免攝像影像產生光點之缺憾，有益手術 的安全進行，獲致實用進步性者。另外，本創作的兩組光源皆提供可調節亮度之控制機構，而可依據腔體大小和深淺位置來調整光源亮度，且因加大了內部的空間，而得以避免光源集中所導致溫度過高的缺點者。
綜而言之，本創作之改良，較習知設計顯具有極佳的進步性，故已符合新型專利之要件，爰依法提出申請，並請早日賜准。
