A kind of guiding type nerve engagement conduit with biodegradability and with biocompatibility,It include: an outer layer tubular body,The body central has a channel for running through the tubular body both ends； The channel includes three guide-tube structures,It is to allow in nerve regeneration the neural beam guide tube that can extend,The nerve regneration of wounded tissue can be correctly guided,Promote nerve regneration that can grow along inner conductor wall,Can also maintain guide-tube structure to consolidate,The characteristics such as mechanical strength is good,The tube wall of the nerve beam guide tube be provided with plural number through-hole,Can increase the exchange rate of physiologically substance and maintain fixed neural beam guide tube,The degradation rate of guiding type nerve engagement conduit. The ontology of the small what outermost layer guiding type nerve engagement conduit of caliber, the pipe range of the nerve beam guide tube, the length difference of the both ends total pipe range of the ontology and neural beam guide tube of guiding type nerve engagement conduit is the suture zone of connection fracture nerve, suture zone is to allow fracture end or impaired nerve that can engage place, fixed impaired nerve is assisted, neural restoration is allowed to provide a starting point.一種具有生物可降解性及具有生物相容性之導引式神經接合導管，包括：一外層管狀本體，該本體中心具有一貫穿該管狀本體兩端的通道；該通道內含三根之導管結構，是讓神經再生過程中可以延伸的神經束導管，能正確地引導受傷組織的神經再生，促使神經再生能沿著內層導管壁生長，亦能維持導管結構穩固、機械強度佳等特性，該神經束導管之管壁設置有複數之通透孔、能增加生理物質的交換率與維持固定的神經束導管、導引式神經接合導管之降解速率。該神經束導管之管徑、管長小於最外層導引式神經接合導管之本體，導引式神經接合導管之本體與神經束導管之兩端總管長的長度差為連接斷裂神經之縫合區，縫合區是讓斷裂端或受損的神經可以接合之處，協助固定受損的神經，讓神經修復提供一個起始點。
