Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to manual bone stirring syringe.
Background
The calcium sulfate artificial bone is a bone repair material taking powder and curing liquid as main components, wherein the powder is high-purity calcium sulfate hemihydrate, and the curing liquid is purified water. The powder and the solidification liquid are mixed to obtain a plastic paste, and the calcium sulfate hemihydrate in the paste gradually reacts with water to produce calcium sulfate dihydrate crystals, so that the calcium sulfate artificial bone is obtained through solidification. The generated calcium sulfate dihydrate is an important bone repair material, has good biocompatibility, degradability, excellent osteogenic performance and osteoconductivity, can be used for reconstructing bone structures and preventing soft tissue ingrowth, creates a good environment for the growth of new bones, and provides an osteoconductive matrix for the ingrowth of blood vessels and osteoblasts. Meanwhile, the calcium sulfate dihydrate has good biocompatibility and biodegradability, the absorption rate after being implanted into a body is basically consistent with the growth rate of new bones, the calcium sulfate dihydrate provides raw materials for the growth of the new bones while degrading, and the calcium sulfate dihydrate absorbs in about 2 to 3 months after being implanted. Therefore, calcium sulfate artificial bones are widely used in clinical surgery for the repair of bone cavities or bone defects/fractures in non-weight bearing sites and for the treatment of dental defects.
The calcium sulfate artificial bone is an artificial bone material taking high-purity calcium sulfate hemihydrate as a key. Calcium sulfate hemihydrate is curable and reacts with a certain amount of water to form calcium sulfate dihydrate to effect cure. Therefore, after the calcium sulfate hemihydrate is mixed with the solidifying liquid, a paste which is arbitrarily shaped within a certain time can be obtained and is completely solidified after a certain time. The paste can be filled into a forming mold to form a desired shape, or directly formed into the shape of a bone cavity, or filled into a syringe to be injected into an open bone cavity/bone fracture and cured in vivo.
The minimally invasive surgery usually adopts the artificial bone filler to carry out artificial bone injection, and the existing artificial bone filler needs to firstly stir the mixture in the bobbin in the using process, takes out the stirring rod after stirring, and then fills in the piston rod to carry out injection.
However, the paste of the existing artificial bone filler is difficult to be uniformly stirred in the using process, and a large amount of air is brought in when the paste is inserted into the piston rod, so that the quality of the artificial bone is reduced.
