Abstract: A balloon, a medical device, and a medical procedure for discoplasty are disclosed. The balloon has a compressed, collapsed or folded balloon body containing a first chamber for, in use, receiving injected bone cement. With the bone cement filled and cured therein, the balloon acts as a support in tissue of an intervertebral disc while preventing the bone cement from leakage and dispersion. The deployed balloon body defines a second chamber running therethrough. The second chamber is configured to receive a material or cells that activate osteogenesis and/or osteo-induction, so that the material or cells injected into the second chamber through a second sprue form osteocytes or induce human spontaneous local cellular differentiation to in turn form osteocytes in the cavity of the intervertebral disc and connect vertebrae above and below the intervertebral disc, thereby securely anchoring the balloon within the intervertebral space.

Abstract: To solve the problem that an excellent carrier material is absent in a storage and use process of the bone morphogenetic protein, based on self-polymerization universality of dopamine, the positively-charged polyelectrolyte, the negatively-charged polyelectrolyte and the ceramic powder with biological activity are integrated onto the titanium base material in a layer-by-layer assembly mode to construct a bone morphogenetic protein slow-release system, so that long-acting slow release, on a lesion part, of the bone morphogenetic protein is achieved. The slow-release system has the advantages of being high in surface modulus, stable, resistant to radiation, good in biocompatibility, and the like, can effectively promote osteogenic differentiation of the mesenchymal stem cells, and can be expected to effectively promote bone repair.

Abstract: A finger-assisted training device and an application method thereof are provided. An electric cylinder drives the sliding sleeve to slide; the sliding sleeve drives two connecting rod mechanisms; the connecting rod mechanism includes four connecting rod assemblies; the connecting rod assembly includes a rocker, a connecting rod and a movable rod; one end of the support is hinged on the support plate, the support is fixed on the support plate; the middle of the rocker is hinged with one end of the connecting rod, and the other end of the connecting rod is hinged with the sliding sleeve; the other end of the rocker is hinged with one end of the movable rod; the other end of the movable rod is fixed with a collar; the fixed arc rod is connected with the movable rod of each link assembly through a spring.
