Description
Technical field
The invention belongs to technical field of medical instruments, in particular it relates to which a kind of fractures marrow inside and outside dual is stable
Fixator.
Background technology
Fracture is that the continuity of bone structure is broken completely or partially.The main cause fractured mainly has three kinds of feelings
Condition：1) direct violence：Violence directly acts on a certain position of bone and causes the position to fracture, and is often damaged with different degrees of soft tissue
Wound.Such as wheel shock shank, fracture of shaft of tibia and fibula occurs at shock.2) indirect violence：By vertical when indirect violence is acted on
Make to fracture at a distance to conduction, leverage or twisting action, when such as falling foot from eminence and landing, trunk is because of gravity relationship
Drastically to pre-buckling, compressibility or bursting fracture occur for the centrum of chest lumbar spine intersection.3) accumulation property strain：For a long time, repeatedly,
Slight direct or indirect damage can cause a certain privileged site fracture of limbs, also known as fatigue fracture, and such as remote walking is easily caused
1/3 shaft fracture under second and third metatarsal and fibula.
The treatment of fracture typically uses replacement and fixation, after the reduction of the fracture, because unstable, easily occurs to shift again, therefore will
Satisfied position is fixed in using different methods, it is gradually healed.Conventional fixing means has：Plintlet, gypsum
Bandage, exterior fixing rack, traction braking fixation etc., these fixing means claim outer fixation.If passing through surgical incision steel plate, steel
Pin, intramedullary needle, screw etc. are fixed, then claim interior fixed.But for the fracture of elongate bone (such as fibula), when fixing, by
In the rotation of internal fixation nail, often fixed effect is bad, and key thin, and lock hole can not be also carried out even if using intramedullary nail and is consolidated
It is fixed.Therefore, need that research and design is a kind of can to overcome the fracture fixing apparatus of disadvantages mentioned above badly.
The content of the invention
It is an object of the present invention to provide a kind of stable fixator of fractures marrow inside and outside dual, the fixator does not need marrow
Interior nail internal lock hole is fixed, can anti-rotation, good fixing effect can prevent fixed effect bad to the secondary of fracture portions
Damage.
To reach above-mentioned purpose, present invention employs following technical scheme：
A kind of stable fixator of fractures marrow inside and outside dual, the fixator includes internal fixation nail 1 and fixed plate 2, described
The upper end of nail rod 11 of internal fixation nail 1 sets some breach 12, and the wedge-shaped lower end of nail rod 11 sets groove 13, and the groove 13 is along nail rod
11 extend to upper end, and groove depth along nail rod 11 from lower end to upper end in shoaling gradually；
Described one end of fixed plate 2 sets the hanging hole 21 hung in breach 12, and the other end of fixed plate 2 is sequentially arranged along plate
Some fixed pressurization holes 22.
In the present invention, groove 13 is used to be close to Kirschner wire, is easy to internal fixation nail 1 to enter interior to the marrow, and accurate positioning, will not make
Internal fixation nail deviates default duct when entering interior to the marrow.
Preferably, the nail rod 11 is flat column or semi-cylindrical.Those skilled in the art can also select as needed
Select other shapes.
Preferably, the quantity of the breach 12 is two or three.Those skilled in the art can also select as needed
Other quantity, such as five etc..The present invention sets multiple breach, is easy in art block from indentation, there the need for according to nail rod length
A part for nail rod, it is time saving and energy saving.
Preferably, the quantity in the fixed pressurization hole 22 is four.Those skilled in the art can also select as needed
Other quantity, such as six etc..
Preferably, the pressurization fixing hole 22 is diplopore, and its inboard aperture 221 is used to fix, and pressurization is set in its apertura lateralis 222
Slope 223.
In the present invention fixed pressurization hole is set to multiple, is easy in art selection as needed using a fixed pressurization hole
The plate that is strained and fixed still selects multiple fixed pressurization holes to be strained and fixed plate.
Preferably, the pressurization slope 223 and outside centerline hole are in 45-60 ° of angle.
Preferably, the fixed plate 2 is strip.Those skilled in the art can also select other shapes as needed.
Such as T-shaped plate.
Preferably, the making material of the fixator is titanium alloy.Those skilled in the art can also select as needed
Other making materials.
Groove in the present invention is arranged on the opposite flank with lozenges of tapered end.
Internal fixation nail is and soft and hard in the present invention, in use, deformation can be carried out with internal structure of bone, so that preferably
It is fixed in bone.
Fixed plate in the present invention can be close on the bone surface of fracture portions, and fixed plate can be according to fracture portions
The different shape of design.
The application method of the present invention：Bone 3 breaks as two parts, fracture end and base bone along fracture line 4, first by internal fixation nail 1
It is screwed into fracture end and through the reasonable length of fracture line 4, the nail rod 11 of the part of breach 12 is exposed to the outside of bone 3, then will be fixed
The hanging hole 21 of plate 2 is hung in breach, is extended by fixed plate 2 along bone 3 to fracture portions, and covers fracture portions, using spiral shell
Nail is screwed into the apertura lateralis 222 of pressurization fixing hole 22, in the fixation procedure, and fixed plate 2 is pulled power effect, tenses hanging hole
And breach, after tensing here, internal fixation nail will not be rotated, and preferably fracture portions can be fixed.Tense hanging hole and lack
After mouthful, then use some screws that fixed plate is fixed on bone.
The present invention is used for Minimally Invasive Surgery, is applicable to the fixation of elongate bone fracture, such as fibula, shin bone, clavicle, breastbone
Deng.
The present invention compared with prior art, the advantage is that：
Fix to nail on to set including the present invention and can tangle the breach of fixed plate, the breach can be with the hanging hole in fixed plate
It is fitted close, so as to prevent the rotation of internal fixation nail.In addition, the present invention sets the pressurization fixing hole of diplopore in fixed plate, can
With the plate that is preferably strained and fixed, the fixation of tension band action effect is played.
