Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to an injection device for filling a bone cavity.
Background
Bone lesions such as osteomyelitis, osteonecrosis, bone cyst, benign bone tumor and the like are clinically removed to form a large bone cavity and form bone defect; moreover, these bone defects are often located at the metaphysis, are located deeply, and make it difficult to perform filling treatments of the bone cavity. At present, the clinical treatment method is usually to open a window, fill the material and use a mandril and the like to carry out pressing implantation, and the implantation is incomplete or the pressing causes the material to break through into the joint cavity.
At present, a pressing filling method is commonly used, and materials easily break through bone cavities to cause disastrous results. Some devices designed for injecting PMMA or injectable bioceramics, for example, have high material requirements, require gel-like materials and have a certain setting time for operation, and cannot be removed once screwed in. In addition, for some specific types of bone diseases such as infections, tumors, etc., some medications are required for local treatment, should be mixed well and filled.
In view of the problems in the related art, the present application proposes a device for effective implantation into cancellous bone to effectively solve the above-mentioned problems.

Therefore, the invention adopts the following specific technical scheme:
an injection device for filling a bone cavity comprises a machine body and a tube cavity connected with the machine body, wherein the tube cavity comprises a sleeve and a helical blade drill rotatably installed in the sleeve, the helical blade drill is rotatably connected with a transmission shaft in the machine body, and the transmission shaft is connected with a crank and a power mechanism; the inner end of the tube cavity is provided with an opening for connecting a syringe.
Preferably, the bottom end of the injector is communicated with the tube cavity, and the upper end in the injector is movably provided with a pushing handle.
Preferably, the spiral blade drill at the opening is provided with a transverse drill edge.

Preferably, the switch button is provided inside the handle.
The invention has the beneficial effects that: after local focus is removed, bone defects are often formed clinically on some bone diseases such as osteomyelitis, femoral head necrosis, bone cyst, benign bone tumors and the like; moreover, these bone defects are often located at the metaphysis, are located deeply, and are difficult to perform filling treatment on the bone cavity; at present, the clinical treatment method is usually to open a window, fill the material and use a mandril and the like to carry out pressing implantation, and incomplete implantation or pressing sometimes causes the material to break through into a joint cavity; by using the technical scheme in the application, the window does not need to be opened, and only one hole suitable for the tube cavity is formed. The bone cavity can be fully filled without being pressed, so that the risk is reduced; meanwhile, the wound is small, the operation is simple, and the infection probability is reduced. For some special osteopathia, when anti-tumor or anti-inflammatory treatment is needed, special medicines and materials can be fully mixed, stirred and injected into a bone cavity, and the method is convenient and reliable. The extruded material is transparent before extrusion, and slowly retreats, and the extrusion force is far smaller than the hitting force; thus reducing the risk of the material breaking through the bone cavity. The operation is convenient, the device does not need to be replaced, and the function of filling the bone cavity can be completed at one time.
