A puncture device (1) is provided with: a front puncture needle (2) which has a needle tip (31) with which a living organism tissue is punctured a shaft (2) which is connected to the front puncture needle (3) a rear puncture needle (4) which is installed to be relatively movable with respect to the front puncture needle (3) along the elongated shape of the front puncture needle (3) and has a needle tip (41) with which the living organism tissue is punctured a wire (5) which moves the rear puncture needle (4) toward the base end of the front puncture needle (3) with respect to the front puncture needle (3) and a thread (6). The rear puncture needle (4) is installed to be movable toward the base end of the front puncture needle (3) with the needle tip (41) thereof facing a direction different from that of the needle tip (31) of the front puncture needle (3). The thread (6) is used when an implant is transferred into a living organism when the implant is buried in the living organism, and one end of the thread (6) is connected to the needle tip (31) of the front puncture needle (3), and the other end is connected to the base end of the rear puncture needle (4).La présente invention concerne un dispositif (1) de perforation doté : dune aiguille (2) de perforation avant qui a une extrémité (31) daiguille avec laquelle un tissu dorganisme vivant est perforé dune gaine (2) qui est reliée à laiguille (3) de perforation avant dune aiguille (4) de perforation arrière qui est disposée pour être relativement mobile par rapport à laiguille (3) de perforation avant le long de la forme allongée de laiguille (3) de perforation avant et présente une extrémité (41) daiguille avec laquelle le tissu dorganisme vivant est perforé dun fil métallique (5) qui déplace laiguille (4) de perforation arrière vers lextrémité de base de laiguille (3) de perforation avant par rapport à laiguille (3) de perforation avant et dun fil (6). Laiguille (4) de perforation arrière est située pour être
