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

Intelligent knee joint tibial platform examination pad module
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.
