Description
Technical field
The present invention relates to operation fixed equipment fields, more particularly to a kind of sternum fixer.
Background technology
Domestic and international most of hearts, pericardium and part are indulged in the treatment that operation on diaphragm etc. needs open chest surgery, and chest is all made of
Hit exactly pathway to carry out, that is, needed when performing the operation entire sternal incisions, needed in treatment end or so two halves breastbone answered
Position is closed, and is commonly used sternum fixer in the process and is fixed, existing sternum fixer often has the disadvantage that：1. conventional
Fixation with steel wire needs sharp property to penetrate intercostal or breastbone, and being easy to damage nerve leads to localized paresthesia；It is easy 2. conventional steel wires are fixed
Damage blood vessel causes bleeding that secondary thoracotomy is needed to stop blooding；3. fixation with steel wire is easy cutting breastbone, especially the elderly and sclerotin is dredged
The breastbone of loose patient causes cortical destruction, breastbone poor healing, breastbone stability to decline；4. existing sternum fixer design
Cumbersome, volume is larger, easily leads to breastbone poor healing, local tissue necrosis, and 5. existing sternum fixers are cumbersome, extends hand
The art time.
Invention content
Above-mentioned in order to solve the problems, such as, the present invention provides a kind of sternum fixer, and main body has quick-disassembly structure, can be with
It is quickly dismantled, both sides configure biped, are convexly curved, and are more bonded breastbone bone face, and breastbone fixes more stable, main body setting
There are Measurement scales convenient for measuring, has ellipsoidal structure in main body, it can be in order to quick shearing both sides body part, in emergency circumstances
The chest time is opened in saving, for this purpose, the present invention provides a kind of sternum fixer, including band tooth latch structure, countersunk head screw, chest
Bone fixation structure, trapezoidal bolt and with tooth clamping structure, the band tooth latch structure and with there is breastbone solid on the outside of tooth clamping structure
Determine structure, the breastbone fixed structure is biped mechanism, and each fixing foot is in rotate the arcuate structure that turns up, and the breastbone is fixed
There are a screwed support structure fixing groove in structure and the junction with tooth latch structure and with tooth clamping structure, screwed support knot when work
Structure fixing groove is connected with external rotatable support structure, there is oval hollow out, the ellipse hollow out on the band tooth latch structure
Respectively there are one the Quick Release slot as quick-disassembly structure, there are a pair of trapezoidal bolt, the ladder in the band tooth latch structure other side on both sides
Have that helical teeth is corresponding with the internal tooth inside tooth clamping structure on the outside of shape bolt, two trapezoidal bolts are inserted into tooth card when work
In binding structure, there is countersunk head screw between two trapezoidal bolts, have scale on the band tooth latch structure and a trapezoidal bolt, institute
It states and is continuous scale with the scale on tooth latch structure and a trapezoidal bolt.
The bottom of further improvement of the present invention, the fixing foot of the breastbone fixed structure is passivity structure, is not allowed in this way
Easily hurt skin.
Further improvement of the present invention, the scale on tooth latch structure and a trapezoidal bolt link up ranging from
2-5cm needs in actual use using different specification general ranges to be 2-5cm.
A kind of sternum fixer of the present invention, has the following advantages that：
1）Main body of the present invention has quick-disassembly structure, dismounting easy for installation；
2）There are Measurement scales in main body of the present invention, for measuring Bilateral chest bone width, Bilateral chest bone width is added as entire chest
Bone width is convenient for the fixator for selecting different size in this way；
3）Two parts of main body of the present invention or so configure fixing foot, turn up arcuate structure in rotation, are more bonded breastbone bone face,
Breastbone is fixed more stable；
4）Fixing foot of the present invention is less compared with monopodia material using biped structure, it is possible to reduce potential tissue infection, toe are blunt
Property structure, reduce damage to intercostal tissue；
5）The present invention is screwed into countersunk head screw using countersunk head screw after the zoarium of left and right sides part, make the gear parts of insertion without
Method loosens, to achieve the purpose that locking；
6）Have in main body of the present invention oval hollow out be two it is less urgent open chest quick-disassembly structure, can cut both sides sheet using cutting pliers
Body portion saves the operating time, gains time to perform the operation to carry out as early as possible；
7）It is trapezoidal that the present invention, which is inserted into locking device, and trapezoidal both sides are oblique type gear.Oblique type gear is compared with vertical gear, and occlusion is more
Tightly, stress bigger ensure that the stability of entire locking device.It is up-narrow and down-wide so that two parts after trapezoidal portions are inserted into locking
It is not easy to loosen；
8）Helical teeth of the present invention is after the completion of fixation, and when both sides strength stretches out, oblique type tooth has downward traveling trend to the right, with to
Left tiltedly type tooth is compared, and is more stablized, and left part without collapsing possibility upwards.
