技術說明

本構想利用夜間飛機跑道以燈光標示之概念，在膽囊切除術時將燈光裝置放入總膽管，讓術者能辨識總膽管位置，使誤傷之事絕跡。目前構想之總膽管內照明裝置，以光纖引導可視光、雷射光或使用LED光源來做為照明，增加手術安全性及杜絕後續醫療糾紛。本創作揭露一種總膽管照明引流裝置，其係於空心套管中設有至少一導管及至少一光纖，此光纖包括至少一出光結構。當此總膽管照明引流裝置進入生物體之管道時，光纖可導引光源產生之光由出光結構射出，並穿透空心套管之管壁與生物體之管道，藉此顯示出管道位置並照明鄰近手術區域。可與目前腹腔鏡手術相結合。讓醫師易於觀察到人體內的總膽管，輸尿管等等，不會傷害到相關組織，可有效避免誤切管道之憾事發生。 Bile duct injury (BDI) is the most serious iatrogenic complication during laparoscopic cholecystectomy (LC) and occurs easily in inexperienced surgeons since the position of common bile duct (CBD) and its related ductal junctions are hard to precisely identify in the hepatic anatomy during surgery. BDI can be devastating, leading to chronic morbidity, high mortality, and prolonged hospitalization. In addition, it is the most frequent injury resulting in litigation and the most likely injury associated with a successful medical malpractice claim against surgeons. This study introduces a novel method for conveniently and rapidly indicating the anatomical location of CBD during LC by the direct fiber-optic illumination of 532-nm diode-pumped solid state laser through a microstructured plastic optical fiber to avoid the wrong identification of CBD and the injury from mistakenly cutting the CBD that can lead to permanent and even life threatening consequences.
