Abstract:
1. A needle-guide device for a medical probe comprising a base body having means for connection to the probe and an elongated guide hole for receiving a needle, characterized in that said needle-guide device is made of at least two removably connectable parts, which are shaped in such a manner that each of them forms complementary and substantially symmetrical parts of the peripheral delimiting wall of said elongated guide hole for a needle, which peripheral wall parts complete each other when said complementary and substantially symmetrical parts of the needle-guide device are connected, thereby forming and maintaining said elongated guide hole for accurately guiding the needle with a 360 degree covering delimiting wall over substantially the entire length of said guide hole, said removably connectable parts being engaged in a non-separable and non-sliding condition by removable mutual mechanical locking means, and said elongated guide hole having rectangular sections dimensioned to contact said needle at needle-guiding surfaces tangent to the outer surface of said needle, thereby restricting transverse movement of said needle in said guide hole.
