Description
Technical field
It the utility model is related to field of medical device, and in particular to a kind of intramedullary expansion self-locking nail.
Background technology
With the continuous development of present social economy, the living standard of people is also constantly being lifted, and people are for life product
The pursuit of matter is also higher and higher.
Especially for present medical industry, orthopaedics is one of most common section office of various big hospital, mainly studies bone
Dissection, physiology and the pathology of muscle systems, keep and develop the normal morphology of this system with medicine, operation and physical method
With function.But general generation fracture condition, quickly heal for the ease of fracture site, it is necessary to be subject to by extraneous equipment
It is fixed, the orthopedic fixation device tool in intramedullary nail category medical instrument.Structure has medullary nailing rod, is equipped with medullary nailing rod near-end near
Screw hole is held, medullary nailing rod surface is provided with decompression Plane.It is elongated that one or more is equipped with medullary nailing rod surface
Decompression Plane, decompression Plane can from medullary nailing rod near-end up to medullary nailing rod distal end.Medullary nailing rod near-end is provided with locking
Screw rod positioning screw hole, connector sleeve locating slot.
But present medullary nailing rod is in use, easily due to the careless activity for hindering patient, since fixation is improper so that
Inconsistent phenomenon occurs for medullary nailing rod, not only brings influence to recovering the positions such as fracture, while can also bring secondary wound to patient is hindered
Evil or operation risk.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of intramedullary expansion self-locking nail, can effectively realize dress
Put effective fixed in bone marrow.
In order to achieve the above object, the utility model is achieved by the following technical programs：
Intramedullary expansion self-locking nail, including nail tube body, inner tube, fixed wing plate, nail tube body centre is hollow knot
Structure, and inner tube is socketed with inside, the inner tube front end side is provided with shrapnel, and the shrapnel is arcuate structure, inside
Spiral on the corresponding nail tube body of pipe end to be connected with fixed wing plate, the fixation wing plate is set with interior pipe end contact site
There is cushion socket, the nail tube body outer surface is provided with rubber spacer, is provided through in the lateral surface of fixed wing plate some
Bolt hole, and fixed screw is provided with bolt hole.
Preferably, the length of the inner tube is less than nail tube body length.
Preferably, the bolt hole is in fixed wing plate staggered sideways distribution.
Preferably, the nail tube body length is 25-40cm.
Preferably, the front edge position of the nail tube body is provided with ring-shaped rubber set.
The utility model provides intramedullary expansion self-locking nail, passes through the inner tube and the mutual set of nail tube body designed on device
Connect effect, and be fixed by fixed wing plate, contact stabilization that can effectively in realization device shrapnel and bone marrow subtracts at the same time
Shake seat can improve the scope of activities of inner tube, and fixed wing plate afterbody is consolidated by the fixed screw being applied in bolt hole again
Fixed, whole device design is reasonable, and simple operation, can be further generalized application.
Brief description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, for ordinary skill people
For member, without creative efforts, other attached drawings can also be obtained according to these attached drawings.
The using state structure diagram of Fig. 1 the utility model；
The non-working condition structure diagram of Fig. 2 the utility model.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Based on this practicality
Embodiment in new, the every other reality that those of ordinary skill in the art are obtained without creative efforts
Example is applied, shall fall within the protection scope of the present invention.
As shown in Figure 1 and Figure 2, the present embodiment provides intramedullary expansion self-locking nail, including nail tube body 1, inner tube 2, fixed wing plate
3,1 centre of nail tube body is hollow-core construction, and is socketed with inner tube 2 inside nail tube body 1, and 2 front end side of inner tube is provided with arc
The shrapnel 21 of shape, it is spiral on the corresponding nail tube body 1 in 2 end of inner tube to be connected with fixed wing plate 3, fixed wing plate 3 and the end of inner tube 2
End in contact position is provided with cushion socket 4, and 1 outer surface of nail tube body is provided with rubber spacer 11, is passed through in the lateral surface of fixed wing plate 3
Wear and be equipped with some bolt holes 31, and fixed screw 32 is provided with bolt hole 31.In use, pass through 2 tail of inner tube
The fixation wing plate 3 that portion is set promotes so that inner tube 2 travels forward, and shrapnel 21 opens, and arrives at the dead angle position in marrow, simultaneously
And be fixed again by the fixed screw 32 being applied in bolt hole 31 in afterbody, when reducing skeleton motion, follow closely tube body 1
The offset of generation, while the design of cushion socket 4 can effectively improve the scope of activities of shrapnel 21.
The length of inner tube 2 is less than nail 1 length of tube body.
Bolt hole 31 is in fixed 3 staggered sideways of wing plate distribution.
It is 25-40cm to follow closely 1 length of tube body.
