Abstract

The invention discloses a microstructure biological material directional cooling preparation device, and relates to the technical field of microstructure biological materials. The microstructure biological material directional cooling preparation device comprises a cold source tank, a placing cylinder is arranged in the cold source tank, a cold conduction mechanism is arranged in the placing cylinder, the cold conduction mechanism comprises a first cold conduction column, one end of the first cold conduction column extends to the outside of the cold source tank and is inserted into a sealing piece, the sealing piece seals the cold source tank and communicates with a material cavity, a sealed heat preservation cover is arranged at an outlet of the material cavity, a directional conduction structure for a cold source to transmit energy to the material cavity along the first cold conduction column is formed, the two ends of the first cold conduction column are located inside and outside the cold source tank correspondingly, and the part, located outside the cold source tank, of the first cold conduction column is provided with a material cavity capable of containing materials. The materials are in contact with the first cold conduction column, energy of a cold source is transmitted to the materials through directional guiding of the first cold conduction column, the conduction direction of the cold source is controlled, then the growth direction of ice crystals is controlled, the material preparation difficulty is reduced, the repeatability is high, the reproducibility is good, and the process is controllable.

Description

technical field [0001] The invention relates to the technical field of microstructure biomaterials, in particular to a directional cooling preparation device for microstructure biomaterials. Background technique [0002] Bone regeneration materials have always been one of the research hotspots of clinicians at home and abroad. The preparation of regular microstructure biomaterials is based on the frontier of bone tissue engineering development and has important bionic and application values. There are many ways to prepare them. For example, using existing Controlled cooling device, through the vacuum freeze-drying method, the solvent in the material is frozen at a low temperature, and the ice crystals in the material are directly sublimated under vacuum or low pressure to obtain a material with a certain microporous structure. The principle of this preparation method Simple, but the disadvantages are: (1) It cannot achieve directional cooling, that is, control the growth dir...
