Abstract
The utility model discloses a knee joint external-rotation angle measuring device, aiming to overcome defects of inaccuracy in reading and higher measuring error in the prior art. The knee joint external-rotation angle measuring device comprises a base, foot supports, a connecting rod, an angle measurer and a voice unit, wherein the foot supports are fixedly connected to the base through the connecting rod, the angle measurer and the voice unit are arranged on the base, and the angle measurer drives the voice unit. The knee joint external-rotation angle measuring device is simple in structure and convenient in operation. Knee joint external-rotation angle of a measured person can be reflected visually, angle of the knee joint can be read out through voice data accurately, and accordingly readability in measurement can be improved, error in manual reading can be avoided, and measuring results can be more accurate.
Description
Technical field
This utility model relates to medical measuring device, is specifically related to a kind of measuring device that voice unit output knee joint closes outward turning joint angle that has.
Background technology
In the clinical treatment of motion surgery, frequently-occurring disease during knee joint injury can make anterior cruciate ligament or the posterior cruciate ligament rebuild lose efficacy to unsettled error diagnosis of external rotation after the knee joint and treatment, and is therefore very crucial to the measurement of back external rotation.The common inspection method that the outer complex in back damages has that physics is had a medical check-up, X line and nuclear magnetic resonance, NMR; The unsettled inspection method of back external rotation for damage causes then has only physics to have a medical check-up, and comprises that the outward turning recurvation is levied, the outward turning dialing of back outer drawer test, enuflex position is tested etc.Wherein, the outward turning recurvation seek peace that the outer drawer test in back differs greatly according to examiner's individual variation difference and not energy rotate unsettled degree; The outward turning dialing test of enuflex position needs to take a picture and just can obtain kneed outward turning angle after the back computer is measured, and needs plural medical assistant to carry out auxiliary detection.Therefore need a kind of knee joint outward turning angel measuring instrument easy to use, simple in structure, that only need single medical assistant just can carry out of research.
Simultaneously, clinical medical development requires increasingly highly to degree of accuracy, also impels each item check result more accuracy, standardization, digitized.Present angle measurement method mainly contains ocular estimate and angle block gauge measurement method: the error of ocular estimate is bigger; Also there is bigger difference in the accuracy that protractor not only uses comparatively and bothers, measures according to operator's practical experience, and the fixed characteristic of its gage beam length makes it be difficult to satisfying personalized measurement requirement.
Summary of the invention
The subject matter that this utility model solved is; Overcome the defective that existing measuring device exists; And a kind of knee joint outward turning angle measurement unit with voice unit output is provided; It can accurately be measured, so that reflect the range of activity in various joints truly according to active characteristics of human body knee joint and clinical medical measuring principle to knee joint outward turning angle.
For achieving the above object, the technical scheme of this utility model is:
A kind of knee joint outward turning angle measurement unit; Comprise base, sufficient holder, connecting rod, angel measuring instrument and voice unit; Said foot holder is fixedly attached to said base through said connecting rod; Said angel measuring instrument and said voice unit are arranged on the said base, and said angel measuring instrument drives said voice unit.
Said angel measuring instrument comprises switch module, power module, angular transducer, analog-digital converter, data processor and coffret; Said power module is connected to said data processor through said switch module, and said angular transducer, said analog-digital converter, said data processor and said coffret are linked in sequence.
Said power module is arranged on the said base.
Said switch module is arranged on the said base.
Said data processor comprises flash chip, can write down many group measurement data.
Said coffret adopts USB interface, Mini-USB interface, blue tooth interface or wireless lan interfaces.
This utility model is simple in structure, easy to operate, not only can quote measured's knee joint outward turning angle intuitively, has also avoided the artificial error that reads, has made measurement result more accurate.
Description of drawings
Fig. 1 is the plan structure view of this utility model one preferred embodiment;
Fig. 2 is the structure chart of this utility model one preferred embodiment angel measuring instrument;
Wherein, 101, base; 102, foot holder; 103, connecting rod; 104, angel measuring instrument; 105, voice unit.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment, structure, characteristic and the effect thereof that proposes according to this utility model, specify as after.
See also Fig. 1:
This utility model comprises base 101, foot holder 102, connecting rod 103, angel measuring instrument 104 and voice unit 105; Foot holder 102 is fixedly attached to base 101 through connecting rod 103; Angel measuring instrument 104 is arranged on the base 101 with voice unit 105, and angel measuring instrument 104 drives voice unit 105.
See also Fig. 2:
Angel measuring instrument 104 comprises switch module, power module, angular transducer, analog-digital converter, data processor and coffret; Power module is connected to data processor through switch module, and angular transducer, analog-digital converter, data processor and coffret are linked in sequence.
Data processor comprises flash chip, can write down many group measurement data.Coffret adopts USB interface, Mini-USB interface, blue tooth interface or wireless lan interfaces.
In the detailed process of knee joint outward turning angular surveying, the job step of this utility model is following:
During concrete the measurement, press switch, the electronic speech unit can be quoted " BM " automatically; After went up to the foot holder at band measuring object station, measuring instrument was started working, and showed knee joint outward turning angle.Can produce the signal of telecommunication constantly when human body is positioned on the measuring instrument, in case the pick off in the said sensing module does not receive this signal of telecommunication, then send reset signal automatically, make whole measuring instrument get back to original state, the electronic speech unit is quoted " BM " again.
