Technical field
The utility model relates to medical instruments field more particularly to a kind of external resetting apparatuses of middle femoral shaft fracture.
Background technique
Femur is longest tubular bone in human body.Fracture of femoral shaft is one of most common fracture, fracture on Orthopedic Clinical
Including the small tuberosity of femur to condyle of femur with upper bit, account for about the 6% of whole body fracture.Since femur is the maximum bone of human body,
And it is one of main weight bearing bone of lower limb, if malpractice, long-term dysfunction and serious deformity can be caused.Femoral shaft
Fracture is mostly caused by High energy trauma, and due to the traction action of muscle, often dislocation is serious for fracture, reset it is difficult, it is most of at
The dry fracture of human femur needs operative treatment, at present there are many ways to operative treatment fracture of femoral shaft, the position of fracture and type, bone
The degree of grinding of folding, the age of patient, the society of patient and economic needs etc. can influence the selection for the treatment of method.Closed reduction
Fixation is considered as the preferred treatment method of fracture of femoral shaft in cross locking marrow nail.
Below femoral bone tuberosity and the shaft fracture away from knee joint 9cm or more was once considered as in closed reduction cross locking marrow nail
Fixed Operation indication.With the proposition of BO (BiologicalOsteosynthesis) theory, treated using minimal invasive techniques
Limbs fracture gradually becomes a kind of trend, and the treatment of fracture was emphasized that Titanic micro-plates reached first intention from originally, and gradually changed
For the fixed viewpoint to reach the second stage of knitting of biology of protection fracture local blood circulation, i.e., biological, reasonable osteopathy
Viewpoint.Treatment to long tubular bone fracture, be also changed by traditional strong fixation of anatomical reduction with maintain long bone normal length,
Do not occur angulation and rotation deformity, the metastable minimally invasive fixation of Indirect reduction for paying attention to the local blood supply of protection fracture.Fracture
Treatment comes into the minimally invasiveization epoch, and closed reduction Interlocking intramedullary fixation technology meets the requirement of fracture biological healing, is
One of the best approach of minimally invasiveization treatment fracture.Femoral shaft around has powerful muscle group wrapping, to sclerite due to anatomy relationship
Angulation stress is generated, in addition fracture of femoral shaft is often muscle and subcutaneous rouge caused by high-energy damage occurs for heavy worker
Fat is abundant, and very big difficulty is brought to closed reduction.Though practical osteology, Campbell's bone surgery all describe femoral shaft
Fracture closed reduction Intramedullary nailing reduction instrument, but due to expensive, domestic manufacturer is in addition to providing Intramedullary nailing at present
System operations tool is not equipped with reduction instrument, and therefore, doctors most of for fracture of femoral shaft still use open reduction interlocking
It is fixed in intramedullary nail, but open reduction causes local damage to aggravate, and often increases infection, local blood supply destroys exacerbation and bone is not cured
The risks such as conjunction, often need comminuted fracture to take bone bone grafting, increase and take bone bone grafting bring local pain, numbness etc. concurrent
Disease.Have been reported that and show that closed femoral fracture cuts the infection rate of drift bolt close to 10%, but the infection rate of closed nailing then less than
1%.
Clinically there are some scholars to describe some reduction instruments, Hebei Medical University third hospital Zhang Yingze professor at present
A kind of femoral fracture closed reduction instrument is described, it is made of hitch frame and supporting plate etc., needs steel nail to fix near end of thighbone, grasps
Make relative complex, fails in clinical wide popularization and application.Shanghai Liu Yuan Xu Haitao doctor describes a kind of diaplasis device for femoral fracture

And the screw hole on three sides of U-shaped framework is screwed into reset bolt, reaches and resets fracture of femoral shaft purpose.Gosling is reported in reset
After being fixed temporarily afterwards using special external fixation to fracture, then row Intramedullary nailing, but specific instrument and operating method are numerous
It is trivial.The closed reduction method that Sun Ruilong etc. is mainly used for rotate, push, mention by etc. Chinese Medicine Close Manipulative Reductions, not using instrument it is auxiliary
Help reset.The kind you of Lu Tingyong, gold obtains good result using small notch, finger exploration technology closed reduction fracture of femoral shaft,
Although notch is small, still there is wound in fracture part, and local periosteum and fracture Peripheral blood are for still centainly being destroyed, not up to really meaning
Minimally invasive and closed reduction in justice.The key technology of fracture of femoral shaft closed reduction self-locking nail internal fixation treatment is how to be closed again
Position, although above-mentioned scholar describes partial reset method and tool, there may be time-consuming and laborious, patient's doctor ray exposures
More, clinical operability is not strong, and therefore, doctors most of for femoral fracture are still based on selecting to fix in open reduction.
Weil etc. thinks that Computer navigation surgery can help to realize more accurate reset, while greatly reducing fluoroscopy during operation number, but counts
Calculation machine auxiliary reset technology is expensive due to needing special installation, and learning time curve is long, can not realize in basic hospital.
