摘要：
A cannulated screw according to the present invention comprises: a body part, which includes a screw thread formed by protruding along an outer side surface and has a through-hole formed in the center thereof； and a head part of which one side surface is coupled to one end of the body part and the other side surface is formed as a curved surface of which the center portion is concave, and having a connection hole, which is formed in the center thereof and communicates with the through-hole. According to the cannulated screw of the present invention, the shape of the head part, which comes in contact with a guide wire, is formed as a curved surface of which the center portion is concave, so as to induce the guide wire to be located in the center thereof, such that a connection hole of the cannulated screw can be easily found. In addition, since a washer formed as a curved surface of which the center portion is concave is further included, the guide wire can be induced to be located in the center thereof even in a range wider than that of the head part, such that the guide wire can be easily inserted into the connection hole. Therefore, the cannulated screw can be quickly and safely removed.Une vis canulée selon la présente invention comprend : une partie de corps qui comprend un filetage de vis formé en faisant saillie le long d'une surface latérale externe et comporte un trou traversant formé au centre de celle-ci； et une partie de tête dont une surface latérale est couplée à une extrémité de la partie de corps et l'autre surface latérale est formée sous la forme d'une surface incurvée dont la partie centrale est concave, et comportant un trou de raccordement, qui est formé au centre de celle-ci et communique avec le trou traversant. Selon la vis canulée de la présente invention, la forme de la partie de tête qui vient en contact avec un fil-guide, est formée sous la forme d'une surface incurvée dont la partie centrale est concave, de façon à amener le fil-guide à ê
