Description
Technical field
The present invention relates to medical instruments field more particularly to a kind of rib cage intramedullary nails.
Background technology
Traditional fracture of rib therapy is gives the patient of fracture of rib analgesic or fixes band outside with chest
It is fixed, although alleviating pain, respiratory state is made to be deteriorated；Secondly, the rib cage board fixer occurred later, to a certain degree
On alleviate the pain of sufferer, and do not interfere the respiratory state of sufferer, but wound area is larger, and needing to do open chest surgery can
It is installed.
Invention content
In view of the drawbacks described above of the prior art, the object of the present invention is to provide a kind of easy to operate, safe and reliable rib cages
Intramedullary nail.
The purpose of the present invention is achieved through the following technical solutions：
A kind of rib cage intramedullary nail, including guide part and fixed part；The material of rib cage intramedullary nail has certain elasticity；It is described to lead
It is disposed on the same plane to portion and the fixed part；One end of the guide part is connected with tapering, the end in the tapering
In arc-shaped；The position that the guide part is connect with the tapering is taper, and identical with the taper in the tapering；The guiding
The other end in portion is connected with the connecting portion；The fixed part is connected with the guide part by the connecting portion；It is described
Connecting portion is parabola or arc shape；The both sides of the fixed part are provided with holding claw；The holding claw and the fixed part are substantially
It is perpendicular；Locking hole is provided on the fixed part.
Further, the locking hole is two；The holding claw is arranged on the fixed part far from the connecting portion
Adjacent one end, one of locking hole are arranged among two holding claws, another locking hole is positioned close to the connecting portion
Side.
Further, the material of rib cage intramedullary nail is pure titanium.
Compared with the existing technology, the features of the present invention and progress are as follows：
1st, the end of rib cage intramedullary nail of the invention has guiding role, convenient for being moved in rib cage in arc-shaped, no wedge angle；
The position that guide part is connect with tapering is taper, and identical with the taper in tapering, and such guide effect is more preferable, is more convenient in rib cage
Interior movement.
2nd, the guide part of rib cage intramedullary nail of the invention and fixed part are disposed on the same plane, and facilitate processing and manufacturing, together
When due to rib cage intramedullary nail have elasticity, the fixation of rib cage intramedullary nail will not be influenced.
3rd, the connecting portion of rib cage intramedullary nail of the invention is parabola or arc shape, reduces stress concentration, when rib cage marrow
It is interior nail into operation path deform when, ensure rib cage intramedullary nail will not be broken.
4th, the holding claw of rib cage intramedullary nail of the invention is arranged on the adjacent one end far from connecting portion on fixed part, one of them
Locking hole is arranged among two holding claws, another locking hole is positioned close to the side of connecting portion, is inserted into and locked by locking nail
Tieholen is further fixed, and can greatly reinforce the reliability of rib cage Intramedullary nailing in this way.
5th, compared to common rib plate, rib cage intramedullary nail of the invention is inserted into pulp cavity, small with wound, easy to operate, suffers from
Person restores fast, good operation effect；Sufferer pain intensity is substantially reduced, increases lung capacity, reduces the generation of lung's complications, is shortened
Average stay.
6th, the present invention is pure titanium rib cage intramedullary nail, and histocompatbility is good, substantially without artifact under X-ray, so can be without taking out.
7th, the geometric center of sclerite is fixed in bone surgery, and rib cage intramedullary nail of the invention can fix fracture in dissection position
It puts；Compared to the fixation with bone plate, it is advantageous that more meeting the stress line of force of human body.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of rib cage intramedullary nail, including guide part 2 and fixed part 4；The material of rib cage intramedullary nail has
Certain elasticity can be deformed voluntarily as needed；Guide part 2 is disposed on the same plane with fixed part 4, facilitates processing and manufacturing,
Simultaneously because rib cage intramedullary nail has elasticity, the fixation of rib cage intramedullary nail will not be influenced；One end of guide part 2 and 1 phase of tapering
Connection, in arc-shaped, no wedge angle has guiding role, convenient for being moved in rib cage for the end in tapering 1；Guide part 2 and tapering 1
The position of connection is taper, and identical with the taper in tapering 1, and such guide effect is more preferable, is more convenient for moving in rib cage；It is oriented to
The other end in portion 2 is connected with connecting portion 3；Fixed part 4 is connected with guide part 2 by connecting portion 3；Connecting portion 3 is parabola
Or arc shape, reduce stress concentration, when rib cage intramedullary nail, which enters operation path, to deform, ensure that rib cage intramedullary nail will not
It is broken；The both sides of fixed part 4 are provided with holding claw 6, can preferably be fixed on dislocation fracture rib cage；Holding claw 6 is with consolidating
It is substantially perpendicular to determine portion 4；Locking hole 5 is provided on fixed part 4, locking hole 5 is two；Holding claw 6 is arranged on separate on fixed part 4
The adjacent one end of connecting portion 3, one of locking hole 5 are arranged among two holding claws 6, another locking hole 5 is positioned close to
The side of connecting portion 3 is inserted into locking hole 5 by locking nail and is further fixed, can greatly reinforce rib cage intramedullary nail in this way
Fixed reliability.
Locking hole 5 is mainly used for when encountering special ribbed shape, when can not lean on holding claw holding fracture rib cage merely, can make
It is locked with locking nail so that preferably rib cage intramedullary nail is lock onto on fracture rib cage.
Further, the material of rib cage intramedullary nail is pure titanium.
As Figure 2-3, rib cage is misplaced；Fracture is operated using rib cage intramedullary nail；Operation side
Method is as follows：（1）Appropriate location at fracture of rib selects entrance, by kit, establishes operation path；（2）Such as Fig. 2
It is shown, after operation path is established, fission 7 surface texture of rib cage is removed, according to actual needs in the rib cage marrow of selection respective model
Nail according to fracture site frame bending degree, is hit exactly with fracture is stuck in after hand pre-bending；（3）As shown in figure 3, with large size or trumpet
Clip Applier carries out a point pawl and applies, and clamp aft rib intramedullary pin is only needed to be loosened not on rib cage；（4）Under special circumstances, if
It does not lock yet, locking nail may be used and be fixed.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Invention, and be not used as limitation of the invention, as long as in the spirit of the present invention, to embodiment described above
Variation, modification will be all fallen in the range of claims of the present invention.
