Abstract
The invention relates to the field of medical apparatus and instruments, in particular to an intelligent knee joint tibia platform test pad module. The intelligent knee joint tibia platform test pad module comprises a tibia platform test pad body which is provided with an accommodating cavity and a force measurement chip which is arranged in the accommodating cavity. The force measurement chip is arranged in the accommodating cavity in the intelligent knee joint tibia platform test pad module, so that the stress distribution situation of the platform on the inner side and the outer side of a knee joint during a moving process can be measuredanddisplayed accurately through pressure sensor probes which are uniformly arranged on a force measurement plate frame when a movement test is performed on athe knee joint; causes are excluded in time in an operation; uniform distribution of the stress is realized; effective cooperation of artificial prostheses of various parts is ensured.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to intelligent knee joint tibial platform examination pad module.
Background technology
Knee joint is the joint that human body is maximum, and many experts both domestic and external and scholar are to activity kneed in normal gait
Studied, find that motion of knee joint is the most complicated, be not simple flexion and extension.Knee joint contains bends and stretches, takes down the exhibits and edge
The rotation of limbs major axis, kneed each type games is to be realized by the linkage of condyle of femur, meniscus, proximal tibial platform and patella
's.Total knee replacement is performed the operation, and is the operation that forever will substitute with upper-part with artificial prosthesis, so, the people of each parts
Whether work prosthese can realize its original physiology anatomical function is to determine the key that complete knee joint Post operation motor capacity recovers.
Existing knee-joint prosthesis mainly includes lateral femoral condyle prosthesis, tibia support prosthese and tibia pad prosthese;Tibia support prosthese
Being presented in patient's tibia, be then fixed on tibia support by tibia pad prosthese, the femoral joint face of patient femur is resisted against
On tibia pad prosthese.The anisopleural stress of tibia pad prosthese, is more easily generated loosening, the mill of prosthese and osseous tissue interface
Damage the destruction of even prosthese.Therefore need to be adjusted by tibial plateau examination pad before implanting tibia pad prosthese, it is ensured that tibia
Pad prosthese lateral symmetry stress.
Display knee joint medial and lateral platform stress in active procedure cannot accurately be measured by existing tibial plateau examination pad
Distribution situation, it is impossible to get rid of the reason causing stress abnormal in art in time.
Summary of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, it is provided that one accurately measures knee joint
Medial and lateral, joint platform distribution of force situation in active procedure, it is simple to the intelligent knee joint tibial platform adjusted in art
Examination pad module.
The present invention is to be achieved by the following technical programs:
Intelligent knee joint tibial platform examination pad module, including being provided with the tibial plateau examination pad body accommodating cavity and being located at
Accommodating the dynamometry chip in cavity, described dynamometry chip includes the force plate being correspondingly arranged at both sides and is located between two force plates
Chip carrier, described chip carrier frame is provided with the battery for power supply, and described force plate includes dynamometry grillage and is uniformly located at dynamometry
Pressure transducer probe on grillage, dynamometry chip is additionally provided with wireless telecommunications mould pressure transducer measured pressure signal exported
Block.
Described pressure transducer probe is cylinder, and pressure transducer probe stretches out dynamometry grillage plane.
The invention has the beneficial effects as follows:
It is provided with dynamometry chip, when knee joint carries out movement test, by uniformly setting in receiving cavity within the present invention
Pressure transducer probe on dynamometry grillage, accurately measures display knee joint medial and lateral platform stress in active procedure
Distribution situation, gets rid of reason in time, accomplishes that stress equalization is distributed, it is ensured that the artificial prosthesis of each parts effectively coordinates in art.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the present invention.
Fig. 2 is the perspective view of the present invention.
Fig. 3 is the installment state schematic diagram of the present invention.
In figure: 1. tibial plateau examination pad body, 2. dynamometry chip, 3. force plate, 4. chip carrier, 5. battery, 6. force plate
Frame, 7. pressure transducer probe, 8. lateral femoral condyle prosthesis, 9. tibia support prosthese, 10. step down portion.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with the accompanying drawings and
The present invention is described in further detail for good embodiment.
Accommodate the tibial plateau examination pad body 1 of cavity as it can be seen, the present invention includes being provided with and be located in receiving cavity
Dynamometry chip 2, described dynamometry chip includes the force plate 3 being correspondingly arranged at both sides and the chip carrier 4 being located between two force plates, institute
Stating chip carrier frame and be provided with the battery 5 for power supply, described force plate includes dynamometry grillage 6 and is uniformly located on dynamometry grillage
Pressure transducer probe 7, dynamometry chip is additionally provided with wireless communication module pressure transducer measured pressure signal exported.
Preferably, pressure transducer probe is cylinder, and pressure transducer probe stretches out dynamometry grillage plane,
In art, after being resetted by intelligent tibial plateau examination pad, knee joint is carried out movement test, be uniformly located at force plate
The pressure transducer probe sensing knee joint medial and lateral platform on frame stressing conditions in active procedure, and by measurement data
Being spread out of by wireless communication module, outside display intuitively shows after data being changed, it is simple to get rid of reason in art in time,
And effectively adjust, accomplish that stress equalization is distributed, it is ensured that the artificial prosthesis of each parts effectively coordinates.
As it is shown on figure 3, be installed on the use state between lateral femoral condyle prosthesis 8, tibia support prosthese 9 for this tibial plateau examination pad
Schematic diagram.
Tibial plateau examination pad body both side surface is adapted to lateral femoral condyle prosthesis and tibia support prosthese is provided with the portion of stepping down 10.
It addition, the mode arranged evenly of the shape of force plate and pressure transducer probe is also designed to meet uses need
The various forms wanted.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications also should
It is considered as protection scope of the present invention.
