PROBLEM TO BE SOLVED: To provide a tracheoesophageal prosthesis detainment device that is safe and easy to introduce and detain at the tracheoesophageal wall of a patient following the tracheoesophageal shunt method, with a small burden placed on the patient.SOLUTION: The tracheoesophageal prosthesis detainment device includes a puncture means having a needle 11 inserted through an endoscope forceps bore mainly via nasal or oral cavity and puncturing the bronchi side from the esophagus side to form a cavity on the tracheoesophageal wall, a coat means (a protective tube 3) interpolating the puncture needle starting from its leading end in the way that the needle may appear and disappear, an expansion means (a dilator 6) to expand the fistula formed, and an introduction means (guide wire 4) in which a prosthesis 5 is introduced and detained at the cavity expanded by the dilator, and the prosthesis is installed at the rear end so that the prosthesis may be severable from the system. Both the puncture means and the introduction means may be formed in one as a flexible wire 7 provided with a puncture needle.COPYRIGHT: (C)2012,JPO&INPIT【課題】気管食道シャント法におけるプロテーゼの気管食道壁への導入、留置が安全かつ容易で、患者への負担の少ない気管食道プロテーゼ留置器具を提供すること。【解決手段】内視鏡の鉗子孔を通して、主に経鼻的、あるいは経口的に挿入され、食道側から気管側に穿刺して気管食道壁に瘻孔を形成する穿刺針11を備えた穿刺手段と、該穿刺針を先端より出没可能に内挿する外套手段(保護管3)と、前記形成される瘻孔を拡張する拡張手段(ダイレーター6)と、該拡張手段により拡張された瘻孔部に経鼻的あるいは経口的にプロテーゼ5を導入、留置する、後端部に前記プロテーゼを分離可能に取り付けた導入手段(ガイドワイヤー4)より構成した。また、前記穿刺手段及び導入手段は、穿刺針付きのフレキシブルワイヤー7として一体に形成しても良い。【選択図】 図1
