The creation provides an effective positioning anesthetic needle or auxiliary Minimally Invasive Surgery. This is an objective identification of ways to help physicians more accurately judge the success puncture, avoid postoperative headache, bleeding or perforation and other complications . In this study, we present a novel epidural needle that allows for the acquisition of optical reflectance spectra from tissue close to the beveled surface. This needle has optical fibers embedded in the cannula that deliver and receive light. With wide spectrometer, light received from tissue is resolved to determine the feasibility of optical tissue differentiation, spectra were acquired from porcine tissues. The creation uses a optical fibe needle in place of a traditional novel epidural inner needle, the fiber ends are connected to a light source and a detector to detect the optical characteristics of the organizations interpretation, provide users with a more objective data. The results of this study suggest that the optical fiber needle has potential to improve the accuracy of epidural space identification and abdominocentesis.本創作提供一種有效輔助麻醉針定位或腹腔微創手術的套組,以一客觀的鑑別方式幫助醫師更精確的判斷成功穿刺,避免醫療穿刺針不當而造成術後頭痛、失血或穿孔等併發症。主要的概念是利用人體各組織成份的差異,而擁有對不同波長的光有不同的反射及螢光特性,同時偵測不同組織有不同光學吸收率及折射率,因而藉由辨識組織達成特殊定位的目的。本創作設計將一傳統穿刺子針已一內含光纖的光學辨識針替代,在光纖末端分別連接一個光源及一個偵測器,用以判讀所偵測組織之光學特性,提供使用者更客觀的數據。101‧‧‧光學辨識針102‧‧‧光針耦合器
