Hold the piston rod of push-in；
Exit portal is provided with the tube wall of the blind end of injection-tube, when the through hole on exit portal and intramedullary nail side wall connects
When logical, the bone filler in injection-tube is released from exit portal by the piston rod being pushed into, and by the through hole in intramedullary nail side wall
Project, be filled between the thing to be fixed where intramedullary nail wall outer surface and intramedullary nail, by the bone filler after solidifying by marrow
Interior nail is fixed on inside the thing to be fixed where it.
Every group of through hole includes radially arranged multiple through holes in intramedullary nail side wall.
Multiple through holes in every group of through hole arrange along intramedullary nail side wall radial equipartition.
The technical scheme of another optional filling scope for limiting bone filler is is provided with multiple in intramedullary nail outer cover
The gauze of tubular, each group through hole in intramedullary nail side wall is accordingly coated respectively by each gauze, makes to project from every group of through hole
Bone filler limited and be filled in around this group of lead to the hole site by gauze.
The technical scheme of another optional filling scope for limiting bone filler is is provided with tubular in intramedullary nail outer cover
Integral gauze, gauze tightened by multiple fastening straps and is separated into multistage, and the corresponding at least one set of intramedullary nail side of cladding in every section
Through hole on wall.
Intramedullary nail and bone filler use degradation material or non-degradable material.
Gauze uses degradation material.
The degradation material is degradable artificial bone material；The non-degradable material is bone cement, autologous bone or different
Body bone.
Intramedullary nail is the arc to match with thing shape to be fixed.
Scale value is provided with the injection-tube, with the amount of the bone filler of instruction filling.
Thing to be fixed is long bone.
The beneficial effect that the present invention is reached：
The intramedullary nail fixation device of the present invention, sets multigroup through hole, in stretching into intramedullary nail in intramedullary nail side wall
Injection device in empty passage by bone filler along through hole injection fillers to the marrow cavity wall of intramedullary nail side wall and long bone between, lead to
Intramedullary nail is fixed bone filler after supersolidification, and fixed position flexibly, firmly, is avoided because fixed intramedullary nail is to length
Damage caused by bone, operation technique is easy, and operating time is shorter；Intramedullary nail and bone filler for being stranded in long bone etc. use
Degradation material, gradually degraded during long knitting, avoid the later stage performs the operation again, simplifies surgical procedure, saves
Surgery cost.
Brief description of the drawings
Fig. 1 is the intramedullary nail schematic diagram of the present invention；
Fig. 2 is the injection device schematic diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
Embodiment 1
As depicted in figs. 1 and 2, the side wall axial length side of intramedullary nail fixation device of the invention along hollow intramedullary nail 1
To the multigroup through hole 11 of setting, an injection device can be ordinatedly stretched into the hollow channel in intramedullary nail, injection device 2 includes one end
Close, the injection-tube 21 that the other end is entrance, bone filler can be accommodated in injection-tube 21.Close to the blind end 211 of injection-tube 21
Tube wall on be provided with exit portal 212, a piston rod 22 can be pushed into by arrival end 213 in injection-tube 21.When piston rod 22 is pushed into
When in injection-tube 21, bone filler is released from exit portal 212, and projects and is filled into marrow by the through hole in intramedullary nail side wall
Between the marrow cavity wall of long bone where nail wall outer surface and intramedullary nail, after bone filler solidification, by Intramedullary nailing
In the long bone where it.
It is preferred that every group of through hole includes radially arranged multiple through holes in side wall, each through hole radially uniformly arranges.
Intramedullary nail and bone filler can use non-degradable material general at present, as intramedullary nail uses metal intramedullary nail
Deng bone filler uses bone cement.
In other embodiments, intramedullary nail and bone filler for being stranded in long bone etc. can use degradation material,
Gradually degraded during long knitting, it is preferred that the time of degraded is corresponding with the speed of knitting, and the degree degraded
Slightly it is later than long symphysis, so that the intramedullary nail and bone filler that after long knitting, are stranded in long bone can realize degraded.
Scale value is provided with the injection-tube of injection device, with the amount of the bone filler of instruction filling.
It is preferred that intramedullary nail is the arc to match with the natural torsion shape of long bone.
Connected by the exit portal for adjusting injection-tube with one of through hole in a certain group of through hole in intramedullary nail side wall
It is logical, the bone filler in injection-tube can be filled to where the intramedullary nail wall outer surface of the through hole position and intramedullary nail
Between the marrow cavity wall of long bone；Rotate injection-tube make exit portal thereon with this group of through hole in intramedullary nail side wall other are logical
Hole is connected successively, so as to realize the intramedullary nail wall outer surface to this group of through hole position and the long bone where intramedullary nail
Marrow cavity wall between circumferential filling fix.As needed, the relative position of injection-tube and intramedullary nail is adjusted, makes injection-tube
Exit portal connected with other group of through hole in intramedullary nail side wall, so as to realize to other through hole positions of intramedullary nail
Surrounding filling is fixed.
