The invention belongs to a medical appliance. The invention provides a perfusion type pedicle screw for solving the problems that the existing pedicle screw has insufficient fixation strength and insufficient stability after implantation, which comprises a hollow screw body, that is a cavity is arranged in the screw body, the cavity is communicated with an injection port arranged on a screw head,an exsudation port communicated with the cavity is further arranged on the screw body, and the exsudation port is completely positioned in the range of being contact with pedicle of vertebral arch after the perfusion type pedicle screw is implanted into spine for positioning of the screw body. The perfusion type pedicle screw can be applied in the transpedicular internal fixation method.
