The present invention relates to a medical device manufactured using the additive manufacturing process (3D printing). It is a medical device used preferably as a bone graft composed of a porous structure based on bioceramics based on β-tricalcium phosphate (β-TCP) or hydroxyapatite, which may or not contain nanostructures in its composition, for example: carbon nanostructures (graphene, graphene oxide, reduced graphene oxide, carbon nanotubes, etc.) and, in preferred embodiments, stem cells and polymeric membrane. Also, the present invention relates to the use of this device as a bone graft and the process of preparing this device.

The present application relates to the field of bone tissue engineering materials, and relates to a synthetic bone repair material with a biomimetic structure.The present application prepares a nano wool protein / hydroxyapatite composite biomimetic bone material through an in-situ mineralization process, and the wool material is dissolved, purified, dialyzed and separated and purified to obtain a wool protein solution.The wool protein solution is mixed with a calcium ion solution, and a proper surfactant, a pH value regulator and a performance control substance are added to obtain a precursor solution.On this basis, the in-situ mineralization reaction is carried out by dropping the phosphate to obtain the nano wool protein / hydroxyapatite composite biomimetic bone material.The composite biomimetic bone material obtained by the in-situ mineralization deposition has high rigidity and toughness, can simulate the organic / inorganic components in human bones, and has good bone replacement performance.

1. A surgical training device comprising a housing and a cassette, wherein the housing comprises a synthetic layer for simulating skin, the cassette for holding one or more organ models in anatomical relationship to one another, the cassette being substantially surrounded by the housing and thereby engageable with the housing to define a body cavity, and the cassette comprising synthetic bony anatomical features as landmarks.

The present invention provides methods for the preparation of synthetic bone grafts which are made of a composition comprising two matrixes, one ceramic including interlocked CDHA crystals, and another of one or more binder(s), the two matrixes being admixture. The method comprises the preparing of an ink composition, the 3D-printing, and the hardening of the binder and ceramic components, in this order.The resulting bone grafts, which are characterized by including the two matrixes in admixture, shows improved mechanical properties as well as excellent biological properties.

The application discloses a camera integrated device and method for maxillary sinus mucosa lifting and synthetic bone delivery, which comprises a main handle, an operation tube installed at the front end of the main handle, a male connector socket installed at the rear end of the main handle, and a camera module installed inside the front end of the operation tube; a transparent protective cover is combined with the front end of the operation tube, and an umbrella-shaped outer edge is arranged on the outer edge of the front end of the operation tube, which is used for controlling the lifting of the maxillary sinus mucosa and providing structural support for the transparent protective cover. The application combines the visual camera module with the sinus mucosa lifting tool, so that real-time observation of the mucosa and the operation area can be realized during the maxillary sinus mucosa lifting process. By providing direct visual guidance, more accurate control of the lifting force and direction of the mucosa is realized, so that the risk of mucosa perforation is effectively reduced, and the safety of the operation is improved.
