The present invention relates to a bone cement feeding device for vertebroplasty, capable of feeding bone cement in a wide range at once. To this end, the bone cement feeding device of the present invention, which has a front end part coupled to a needle inserted in a vertebral body to feed bone cement into the vertebral body, comprises: a feeding pipe made of a soft synthetic resin, inserted in the needle from a rear end part of the needle, and having a front end thereof inserted into the needle to have a structure protruding from a front end of the needle; and an operation unit inserted into the feeding pipe from a rear end part of the feeding pipe, having a front end thereof inserted to be identical to a front end of the feeding pipe or to be disposed in an adjacent position, having an ensured space for feeding bone cement into the vertebral body by bending a front end thereof together with a front end of the feeding pipe through selective pulling of two built-in wires, and separated from the feeding pipe to feed bone cement through the feeding pipe. |
