The invention provides a punching gun for bone cement dispersion, and belongs to the technical field of orthopedic surgical instruments. The punching gun acts on a bone. The punching gun comprises a holding part, which comprises a holding body and an action handle that is movably connected to the holding body; a barrel; a drilling strip, wherein the direction of the inner core strip towards the contact head is a first direction; push blocks, which comprise a push block body that is provided with a through groove which is through in the front-back direction, and are arranged on an inner core strip in a sleeving manner based on the through groove; and an actuating mechanism, wherein the push blocks are stacked on the inner core strip in the first direction, and the push blocks located on the rear side of the first direction forwards push an abutting head to move towards the interior of the bone through a push assembly; and the technical effects that bone cement is uniformly dispersed in the bone and the firmness of the bone cement in the bone is ensured are achieved.
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...
