PROBLEM TO BE SOLVED: To provide a medical device for nerve regeneration in which the suturing operation is not required when being connected to the nerve, and the joining with the nerve can be established easily and promptly without requiring an advanced proficiency.SOLUTION: The medical device 105 for nerve regeneration includes: a hollow tube 110 and a connection 120 that connects a nerve 30 to each of both ends of the tube. The connection includes: a contact member 130 freely contacting to the circumference of the nerve a pressing member 140 giving a pressing power pressing the contact member toward the diameter direction inside of the nerve to the contact member a first engaging part 231 (ring groove 222) installed in the contact member a second engaging part 232 (circumference ring section 224 of stopper ring 223) installed in the pressing member and freely engaging with the first engaging part installed in the connect member and a third engaging part 233 installed in the contact member or the pressing member and freely engaging with the tube. In addition, the pressing member is made to give the contact member the pressing power by connecting the first engaging part and the second engaging part.COPYRIGHT: (C)2013,JPO&INPIT【課題】神経と接合するときに縫合作業を必要とせず、高度な熟練性を要することなく神経との接合を容易かつ迅速に確立し得る神経再生用医療デバイスを提供する。【解決手段】神経再生用医療デバイス105は、中空のチューブ体110と、チューブ体の両端部のそれぞれに神経30を接続する接続部120とを有する。接続部は、神経の外周に接触自在な接触部材130と、接触部材を神経の径方向内方に向けて押付ける押付力を接触部材に付与する押付け部材140と、接触部材に設けられた第1の係合部231(リング溝222)と、押付け部材に設けられ第1の係合部に係合自在な第2の係合部232(ストッパリング223の外周リング部224)と、接触部材または押付け部材に設けられチューブ体に係合自在な第3の係合部233とを含む。そして、第1の係合部と第2の係合部とを係合することによって、押付け部材が押付力を接触部材に付与するようにしている。【選択図】図2
