Immediately nuclear magnetic resonance check is further carried out, finer imaging data is also can only obtain, cannot equally obtain
Biomechanical data further, while nuclear magnetic resonance check is referred to as " goldstandard " of injury of knee joint diagnosis, but largely faces
Bed imaging data shows that nuclear magnetic resonance check still remains false positive and false negative result.Before false negative reason is slight
Ligamentaum cruciatum partial injury, MRI signal are without exception；And causes of false positive is that anterior cruciate ligament is not damaged, due to mucus in ligament
Sample is denaturalized or thermophilic Yihong denaturation occurs and abnormal signal occur.It, can at anterior cruciate ligament attachment when carrying out MR antidiastoles
It is in medium to high RST to have fat, synovial membrane, TWI, is easy to be mistakenly considered ligament injury；Certain older patients, anterior cruciate ligament
Fiber regression may occur in which msp signal shadow in ligament, and it is ligament injury to be also easy mistaken diagnosis.
With popularizing for "sport for all", Athletic Injuries In The Knee includes that cross ligament damage is increasing.Many knees close
When section ligament injury suspected patient is to hospital, part doctor just advises patient's row core after carrying out physical examination without training physical examination or simply
Magnetic resonance examination, using the relatively expensive property the made a definite diagnosis diagnostic techniques of price as initial screening means, MRI checks that negative rate is gradual
Increase, causes unnecessary society, economy and medical resource waste.On the contrary, part young doctor is because correctly cannot skillfully slap
Ligamentous injury of knee joint physical examination method is held, early stage negative exclusion has been carried out to light moderate lesion patient, and then delay treatment.Cause
This, which compels to be essential at present, combines the improvement training physical examination based on quantitative biomethanics inspection, how to design a kind of object can it is light and
The degree of injury that ground accurately measures anterior cruciate ligament of knee joint is easily lifted, insoluble technical barrier for a long time is become.
In view of the foregoing, a kind of ligamentous injury of knee joint measuring device is now developed.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of anterior cruciate ligament of knee joint damage

The utility model to achieve the goals above, adopts the following technical scheme that：A kind of knee-joint cross ligament damage
Measuring device, be by：Mainboard, upper cushion block, lower cushion block, bracing wire, frenulum, jack, measuring scale, touch panel are constituted；It is upper on the inside of mainboard
Cushion block and lower cushion block is respectively set in lower end, and bracing wire is arranged above upper cushion block, and two tether panels, mainboard lower section two is arranged in end of pulling
Two tether panels are arranged in side, and jack is arranged above mainboard, measuring scale is arranged in jack, the measuring scale end setting on the inside of the mainboard
Touch panel.
The bracing wire uses elastic band.
The frenulum is one such using snap fastener or velcro or hidden discount or tether.
The end face of the upper cushion block or lower cushion block uses inner concave arc surface.
The end face of the touch panel uses inner concave arc surface.
The utility model has the beneficial effects that：The utility model intersects before easily accurately capable of measuring knee joint
The degree of injury of ligament solves insoluble technical barrier for a long time.Injury of cruciate ligament of knee joint subsidiary fills
The design set is based on pathological anatomy and Mechanics of Machinery principle.When cruciate ligament or fracture, knee joint fore-and-aft stability
It reduces, femoral head increases relative to tibial plane displacement distance.Kneecap and femoral head be bone contact (do not consider dislocation of the patella,
The special circumstances such as synovial bursa hyperplasia), relative position is relatively fixed.The lower cushion block of mainboard lower end is using distal tibia as fulcrum, on mainboard
The upper cushion block at end is using kneecap as fulcrum.It is aggravated with cross ligament damage degree, proximal ends of tibia is therewith with respect to femur Forward distance
Increase.Tibial tubercle is that proximal ends of tibia easily touches bony structure, and vertical tibial tubercle places a ruler, by loading main frame structure
And it is relatively fixed.Ruler can get respective value with the distance that shin bone moves forward, and then realize quantitative check.In use, passing through master
The upper cushion block of plate upper end is pressed on kneecap, and two tether panels of bracing wire and end of pulling above upper cushion block are firmly secured to thigh
