Abstract

The invention discloses a composite bone grafting device which comprises a bone grafting sleeve, a bone grafting funnel, a large porous push plate, a large nonporous push plate, a porous push plate push-pull rod and a nonporous push plate push-pull rod. The composite bone grafting device is characterized in that the bone grafting funnel is arranged on the side surface of the bone grafting sleeve; the large porous push plate and the large nonporous push plate are arranged in the sleeve; the large porous push plate is arranged below the large nonporous push plate; the porous push plate push-pull rod sleeves the outer side of the nonporous push plate push-pull rod; a nonporous push plate and a small porous push plate can be separated out from the large nonporous push plate and the large porous push plate respectively; the porous push plate push-pull rod and the nonporous push plate push-pull rod are provided with corresponding connection structures; after the porous push plate contacts the nonporous push plate, the porous push plate push-pull rod is connected with the nonporous push plate push-pull rod. Screening is further carried out on a broken bone before bone grafting; the uniformity of the broken bone is ensured; compaction on the grafted bone can be ensured through the arranged separable small porous push plate and nonporous push plate; the success rate of the operation is ensured; the bone grafting time can be shortened.

Description

technical field [0001] The invention belongs to orthopedic medical instruments, in particular to a broken bone transplantation instrument used in bone transplantation operations, in particular to a composite bone grafting instrument. Background technique [0002] Bone grafting mainly uses surgery to move bone tissue to the bone defect in the patient's body, which needs to be strengthened or fused. In many cases, it is necessary to implant broken bone into the bone defect. Therefore, in the operation process, it is often necessary to transfer the broken bone to the bone defect with the aid of a bone grafter. Existing bone grafting devices generally use a bone graft tube. During use, bone tissue is often placed at the rear end of the bone graft tube, and then the bone tissue is moved out from the front end of the bone graft tube and reaches the bone graft through a push-pull rod. position, the above-mentioned bone grafting apparatus is loaded down with trivial details to use,...
