Description
Technical field
The present invention relates to a kind of acromioclavicular joint anatomical form locking steel plates.
Background technique
Complex is suspended in midair above the articular fracture dislocation damage of beak lock and omoplate currently, fracturing and merging for acromioclavicular joint
The case of damage there is no special effective internal fixation apparatus.For the patient of such high-energy damage, due to existing inside-fixture
Defect and deficiency, frequently result in and leave heavier disabled and dysfunction.
Existing various inside-fixtures, including clavicle dissection armor plate, clavicular hook plate, hollow screw, tension band wire,
Endo-button, LARS artificial ligament；Clavicle dissection armor plate can only fix clavicle, not be capable of fixing dislocation of acromioclavicular joint；Clavicle hook
Steel plate can only rigidly fix II degree of acromioclavicular joint, III degree of dislocation, need acromion position bony structures complete, for merging acromion bone
The case of folding cannot provide mechanical stability.Hollow screw can only fix the acromial fracture of II type of OGAWA parting, not can solve
The problem of dislocation of acromioclavicular joint and ligament injury；Tension band wire can only fix the acromial fracture of I type of OGAWA parting, cannot
Solve the problems, such as dislocation of acromioclavicular joint and ligament injury；It is de- that III degree of acromioclavicular joint is repaired in Endo-button application flexible fastening
Position not can solve the case for merging fracture；The fixed III degree of acromioclavicular joint of reparation of LARS artificial ligament applied biomechanics principle is de-
Position not can solve the case for merging fracture.
Summary of the invention
The present invention relates to a kind of acromioclavicular joint anatomical form locking steel plates, for treating acromioclavicular joint multiple fracture and omoplate
When suspending complex injury in midair, it is placed in clavicle distal end and mesoscapula upper surface, reaches anatomical reduction, suspention support shoulder joint is controlled
Purpose is treated, the structural strength of suspention side upper limb is sufficiently achieved.
The present invention uses following technical characteristic: a kind of acromioclavicular joint anatomical form locking steel plate, including steel plate, the steel plate
L-shaped 45 degree of angle radians, L-shaped one end are clavicle end, and other end is mesoscapula end；The clavicle end is provided with four pieces of lockings
Hole, the mesoscapula end are provided with five pieces of lock holes, and L shape turning point is provided with five pieces of lock holes.
The present invention also has the following technical effect that
1, the L shape turning point front and rear edges are relatively thin, thicker in the middle part of L shape turning point.
2, the leading edge of the L shape turning point is bent downwardly.
3, the two sides at the mesoscapula end are sawtooth arc, play the role of limitation contact, are guaranteeing steel plate mechanics knot
While structure intensity, stress shielding is avoided the occurrence of.
4, the clavicle end is higher than mesoscapula end 1cm.
The present invention has the advantages that and advantage: this steel plate meets the height on solid space between clavicle and mesoscapula
The change of divergence is spent, dissection radian is carried, biplane locking is formed and fixes, better bone holding power and stability can be provided, had
Higher suspention intensity, fixing intensity is higher, and mechanical stability is good.This steel plate L shape turning point front and rear edges are relatively thin, to local skin
Skin soft tissue excitation is smaller, and middle part is thicker, meets the characteristics of local stress load is concentrated.Nonabsorable suture can be used
Artificial ligament repairs rotator cuff defect and rebuilds rotator cuff.Through mechanics detection and finite element analysis, the effect compared with traditional therapy
Well.

Specific embodiment
Below according to Figure of description citing, the present invention will be further described:
Embodiment 1
As shown in Figs 1-4, a kind of acromioclavicular joint anatomical form locking steel plate, including steel plate, the L-shaped 45 degree of angles of the steel plate
Radian, L-shaped one end are clavicle end 2, and other end is mesoscapula end 1.The clavicle end 2 is higher than mesoscapula end 1cm, completely
It is bonded mesoscapula and clavicle distal end, it is ensured that each piece of locking nail is attained by the mechanical support of maximum intensity.L shape turning point 3
Leading edge 4 is bent downwardly.3 front and rear edges 4.5 of L shape turning point are relatively thin, and the middle part 6 of L shape turning point 3 is thicker.The mesoscapula end 1
Two sides be sawtooth arc, play the role of limitation contact, while guaranteeing steel plate mechanical structure intensity, avoid the occurrence of stress
It blocks.Acromioclavicular joint anatomical form locking steel plate size is 150*45mm, shares 14 pieces of 3.5mm nail hole and 10 pieces of 2.0mm nail hole,
To lock nail hole, 2 four pieces of the clavicle end 3.5mm lock hole, five pieces of mesoscapula side 3.5mm lock hole, L shape turning point 3 is opened
There are five pieces of 3.5mm lock holes, convenient for repairing rotator cuff using nonabsorable suture is fixed.The present embodiment is dual force arm load-carrying members,
Angle stability is good.Through mechanical test, compared with traditional single arm of force methods of internal fixation, there is higher anti-load intensity and resist
Spin intensity.All locking nails are designed by amechanical angle, are individually fixed in clavicle and the most fine and close position of mesoscapula sclerotin, can be mentioned
It is obtaining the result is that stability is better than tradition by mechanical test and finite element analysis for better bone holding power and stability
Methods of internal fixation.The present embodiment is attached at clavicle upper surface and mesoscapula upper surface, for treating acromioclavicular joint fracture dislocation, rises
To the therapeutic purposes of Titanic micro-plates, the shortcomings that overcoming existing acromioclavicular joint technique for fixing, according to acromioclavicular joint region
Anatomical structure and mechanics feature rebuild the stability of acromioclavicular joint, play strong fixed clavicle distal end and acromion, reach the suspention upper arm
The effect of bone surrounding ligaments and upper limb shoulder girdle stability can undertake 20kg weight by mechanical test, sufficiently achieve outstanding
Hang the structural strength of side upper limb.
