The utility model discloses a kind of morphology detection devices of calcium phosphate bone material in the technical field of bone substitute material detection, including rack, scanning electron microscope, holder, control unit and the flexible detection platform for fixedly placing calcium phosphate bone material, flexible detection platform includes the upper clamping piece and lower clamping piece of vertical spacing adjustable, upper clamping piece includes several longitudinal pressure ropes, lower clamping piece includes several horizontal pressure ropes, longitudinal pressure rope and horizontal pressure rope are used to adapt to the outer contour of different morphologies of calcium phosphate bone material by tensile deformation to hold calcium phosphate bone material.The utility model provides the morphology detection device of calcium phosphate bone material, through the cooperation of longitudinal pressure rope and horizontal pressure rope, the effect of stably clamping different sizes and different outer contour structures of calcium phosphate bone material is realized, and the convenience and detection effect of morphology detection to calcium phosphate bone material are improved.

An apparatus for maxillary sinus mucosa dissection and elevation, in humans or in animals, that lifts said mucosa away from the maxillary bone by injecting a fluid through an osteotomy or a hole in the maxillary bone to create an artificial space between said mucosa and the maxilla, that artificial space is to be subsequently filled with bone substitute or a dental implant or both, this apparatus is used in a new method to determine intra operatively whether the sinus mucosa is successfully lifted, along with the height of the lift, or if it has been perforated.

This invention belongs to the field of bone replacement material technology, specifically relating to a porous biodegradable bone replacement scaffold and its preparation method. The porous biodegradable scaffold of this invention consists of pillars, each pillar having an outer shell and a core. The outer shell comprises ZnO, and the core comprises Zn. The porous biodegradable bone replacement scaffold of this invention has a nano- to millimeter-level hierarchical pore structure, which is more similar to the structure of human bone. Furthermore, its degradation performance, antibacterial properties, and biocompatibility are superior to existing biodegradable metallic bone implant materials (zinc and its alloys), which helps promote osteogenic differentiation.
