Description
technical field [0001] The invention relates to the technical field of orthopedic surgical instruments, in particular to a perforating gun for bone cement dispersion. Background technique [0002] Bone cement is a common name for bone cement and a commonly used medical material for orthopedic surgery. Because of its physical properties and its appearance and properties after solidification, it is quite similar to white cement for construction and decoration, so it has such a popular name. The main component of bone cement is polymethyl methacrylate. In the storage state, bone cement is composed of white powder and colorless liquid with pungent odor. When using it, just pour them together according to a certain proportion. Polymerization can take place at room temperature. The reaction starts like mortar, then turns into gruel, and then turns into dough, which can be kneaded and extruded into any shape, and finally solidifies gradually. The whole process only takes ten minut...
