Bone grafting device

The utility model discloses a bone grafting device which comprises an outer sleeve provided with a front opening and a pushing rod inserted into the outer sleeve and capable of moving in the axial direction of the outer sleeve back and forth. A grab handle is arranged at the rear end of the outer sleeve, a rotating handle is hinged to the grab handle, and the tail end of the rotating handle is hinged to the rear end of the pushing rod. An elastic element is installed between the grab handle and the rotating handle and is used for enabling the rotating handle to be reset so as to drive the pushing rod to be reset backwards and be away from the front opening of the outer sleeve. The outer sleeve, the pushing rod and the rotating handle of the bone grafting device are designed to be combined so that the bone tissue can be arranged at the front-end position of the outer sleeve through the front opening in the using process, the pushing rod can be forwards pushed by pulling the rotating handle, the bone tissue can be pushed out by utilizing the pushing rod for bone grafting, a bone tissue moving path can be shortened, and under-microscope intervertebral or percutaneous transpedicular bone grafting can be facilitated. In addition, the structure of the front-end portion of the outer sleeve is reasonably arranged, so that arrangement and pushing of the bone tissue are further facilitated.
