Provided is a system for accurately implanting a bifurcated vessel stent the bifurcated vessel comprises a main blood vessel (101) and a branch vessel (102), which are in communication with each other the system for accurately implanting a stent comprises a stent delivery apparatus (103) capable of releasably stowing and delivering a stent (104), a directing guidewire (105) extending from the main blood vessel to the branch vessel, and a positioning guidewire (106) extending along the main blood vessel the stent delivery apparatus is movably sleeved around the guiding guidewire the stent is provided with a limiting hole (1061), and the positioning guidewire passes slidably through the limiting hole. After the stent enters the branch vessel, the stent guidewire catches at the opening of the branch vessel, such that the stent can be positioned in the axial direction and in the circumferential direction, and the stent can be implanted accurately in the bifurcated vessel the stent is accurately fitted at the opening portion in particular, thus the fit with the bifurcated vessel is good.Système dimplantation précise dendoprothèse au niveau de la ramification dun vaisseau sanguin, laquelle ramification comprend un vaisseau sanguin principal (101) en intercommunication et des ramifications (102) reliées au vaisseau sanguin principal et lequel système dimplantation précise dendoprothèse comprend une endoprothèse de réception détachable (104), un dispositif de transport (103) dendoprothèse, un fil guide (105) sétendant depuis le vaisseau principal jusquà la ramification ainsi quun file guide de positionnement (106) sétendant le long du vaisseau sanguin principal, le dispositif de transport de lendoprothèse entourant amovible le fil guide, un orifice de limitation (1061) pratiqué sur lendoprothèse étant traversé par le fil guide coulissant. Lintroduction du fil guide de lendoprothèse dans la ramification du vaisseau sanguin permet de coincer le vaisseau ramifié au niveau de l
