Description
Technical field
The present invention relates to medical instruments field, more particularly to a kind of sternal bar.
Background technology
, it is necessary to carry out the fixation of closing up of breastbone after traditional cardiothoracic surgery open chest surgery, but the drawbacks of having certain：2
Secondary open chest surgery overlong time, and sternal bar easily retreats, not tight；When sternal bar is removed, destructible wound, extension wound is healed
The conjunction time；The certainty destruction of sclerotin；Because destructiveness is removed, sternal bar cannot secondary installing；The convalescence of sufferer is extended,
The risk of infection is increased, pulmonary infection etc. is indirectly caused；Complex operation and inconvenience；Traditional sternal bar in unloading process,
Because breastbone healing needs certain cycle, until when needing to remove after healing completely, sternal bar may periphery grown in a organized way, meat
Deng, sternal bar perienchyma, meat need to be first removed, can be sheared.Additionally, traditional sternal bar fix tightly solidity not enough, is held
Easily phenomenon is got loose, and also result in lung inflammation, the complications such as atelectasis；It is traditional, it is necessary to dismantle after breastbone healing
Method is to need to use removal tool special, cuts sternal bar, can just remove the sternal bar fixed.
The content of the invention
In view of the drawbacks described above of prior art, it is an object of the invention to provide a kind of fixed, convenient dismounting, safety can
The sternal bar for leaning on.
The purpose of the present invention is achieved through the following technical solutions：
A kind of sternal bar, including upper plastron, middle plastron, lower plastron, fixed nail and locking nail；Upper plastron leads to middle plastron
Locking nail is crossed to connect as one；Hook part is provided with lower plastron, lower plastron is additionally provided with sliding rail, is provided with sliding rail solid
Fixed nail；The bottom surface of sliding rail is provided with locking tooth；The bottom surface of middle plastron is provided with locking tooth, is provided with middle plastron recessed
Portion, is provided with two cylinder boss on recess, hole is threaded on two cylinder boss；It is provided with upper plastron and is matched with recess
The auxiliary section of conjunction, is provided with two circular holes coordinated with cylinder boss on auxiliary section, hook part is provided with upper plastron；Upper plastron
Bottom surface is provided with locking tooth；Middle plastron, the locking tooth of upper plastron are engaged with the locking tooth of lower plastron；Upper plastron and middle chest
Movable block is respectively arranged with plate, movable block links together, and is unidirectionally slidably matched with sliding rail.
Further, fixed nail is made up of relative two planes and two relative cambered surfaces.
Compared with the existing technology, the features of the present invention and progress are as follows：
1st, it is fixed using sternal bar of the invention, substantially reduce fracture of sternum operating difficulty；
2nd, sternal bar of the invention is used, it is to avoid respiratory movement causes later stage fixture to release etc. to occur, can rapidly recover thorax
Shape, hence it is evident that mitigate pain；
3rd, using sternal bar of the invention, in early days can out-of-bed activity, reduce lung inflammation, the complications such as atelectasis and occur, typically
Patient shortens the hospital stays without using lung ventilator, improves the quality of living, and labour has been recovered to greatest extent；
4th, sternal bar of the invention can be dismantled conveniently；
5th, when sternal bar of the invention is dismantled, sternal bar is removed from breastbone by only need to backing out locking nail, it is convenient rapid；
6th, upper plastron of the invention（Middle plastron）, lower plastron contact surface be provided with and be engaged lock tooth, with stopping function；
7th, fixed nail of the invention plays a part of to position and prevents plastron from rocking.

Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As Figure 1-4, a kind of sternal bar, including upper plastron 5, middle plastron 2, lower plastron 1, fixed nail 3 and locking
Nail 4；Upper plastron 5 is connected as one with middle plastron 2 by locking nail 4；Hook part 7 is provided with lower plastron 1, lower plastron 1 also sets
There is sliding rail 8, fixed nail 3 is provided with sliding rail 8；The bottom surface of sliding rail 8 is provided with locking tooth 6；Middle plastron 2
Bottom surface is provided with locking tooth 6, as shown in fig. 7, being provided with recess 9 on middle plastron 2, two cylinder boss is provided with recess 9
11, it is threaded hole on two cylinder boss 11；The auxiliary section 12 being engaged with recess 9, auxiliary section 12 are provided with upper plastron 5
On be provided with the circular holes that two and cylinder boss 11 coordinate, hook part 10 is provided with upper plastron 5；The bottom surface of upper plastron 5 is provided with
Locking tooth 6；Middle plastron 2, upper plastron 5 are provided with the locking tooth 6 being engaged with the contact surface of lower plastron 1（Form lock tooth）, tool
There is stopping function；Movable block 13,14 is respectively arranged with upper plastron 5 and middle plastron 2, movable block 13,14 links together, with
Sliding rail 8 is unidirectionally slidably matched.
Fixed nail 3 relative two planes and two relative cambered surfaces as shown in figure 5, be made up of；As shown in fig. 6, according to
Demand, can adjust fixed nail, the cambered surface of fixed nail 3 is propped up the side of plastron 5 and middle plastron 2, it is ensured that upper plastron 5 is not outer
Turn over.Fixation nail 3 plays a part of to position and prevents the double swerve of plastron 5.
The concrete operating principle of the sternal bar is as follows, installs the process of sternal bar as shown in figure 8, being resetted using Special surgical
Pincers, during by upper plastron 5, lower plastron 1, the direction as arrow in Fig. 8 shown in is poly-, fixation by the nail 3 that is locked, due to upper plastron 5
（Middle plastron 2）, the contact surface of lower plastron 1 be provided with and be engaged lock tooth, with stopping function；, it is necessary to by chest after breastbone heals
When hone lamella is unloaded, as shown in figure 9, after can be used specific purpose tool to back out locking nail 4, it is possible to remove plastron 5.
After open chest surgery, the breastbone of the left and right sides is separated, and now needs to fix breastbone；Now use the sternal bar
Mechanism as shown in figs. 10-12,（1）After cardiothoracic surgery open chest surgery, a sternal bar is taken, unclamps the bolt on sternal bar,
It is placed on breastbone crack J both sides；（2）Sternal bar is placed in breastbone crack both sides；（3）Using Special surgical reduction forceps, will be upper
During plastron 5, lower plastron 1 direction as shown in arrow in Figure 12 are poly-；（4）Be locked nail 3, and fixed 3 lower end screw threads of following closely are by slide nut
Block is tightly pinned, so that upper plastron 5, lower plastron 1 fit together.
But, those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to explanation originally
Invention, and be not used as being limitation of the invention, as long as in spirit of the invention, to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
