Flat valgus correcting force measuring instrument

Abstract

The invention relates to the field of medical apparatuses, in particular to a flat valgus correcting force measuring instrument. The flat valgus correcting force measuring instrument comprises an outer frame. The outer frame is composed of a left supporting frame body, a right supporting frame body and a middle partition plate. The middle partition plate is arranged in the middle of the left supporting frame body and the middle of the right supporting frame body. A force measuring table is arranged on the left supporting frame body. Two opposite cameras are arranged on the two sides of the surface of the force measuring table. A pressure sensor is arranged at the bottom of the force measuring table. A right platform is arranged on the right supporting frame body. A strip-shaped groove through hole is formed in the middle of the middle partition plate. A linear pushing rod is arranged at the bottom of the outer frame. One end of the linear pushing rod penetrates through the strip-shaped groove through hole to be movably connected with a linear displacement sensor. An angle sensor is connected to one side of the linear displacement sensor. The flat valgus correcting force measuring instrument has the advantages of being simple in structure, rapid and convenient to use, and capable of rapidly measuring the magnitude and the direction of correcting force, the displacement of the navicular bone and the deflection angle of the heel axis in the correcting dynamic condition of the whole foot.

Description

【Technical field】 [0001] The invention relates to a medical device, in particular to a flat valgus foot correction force measuring instrument. 【Background technique】 [0002] Flatfoot valgus refers to the collapse of the arch of the foot and the lateral deviation of the heel axis, usually with an valgus angle of more than 5 degrees. The degree of foot valgus deformity varies greatly, and there are many different types of manifestations. Each type has different characteristics, and the treatment methods are also quite different. Therefore, how to reasonably evaluate and classify foot valgus deformity is correct. It is an important basis for choosing a treatment plan and optimizing the design of orthotics, and plays an important role in the treatment of foot valgus deformity. [0003] In the traditional technology at the present stage, the evaluation of foot valgus mainly adopts the method of plantar pressure measurement and analysis technology and foot geometric feature valu...

Problems solved by technology

[0005] The object of the present invention is to aim at the defects and deficiencies of the prior art, to provide a kind of flat valgus foot correction force measuring instrument with simple structure, reasonable design and convenient use. In terms of plantar pressure and geometric feature measurement, it is an instrument designed without considering the deformation characteristics of the foot under the action of external load; on the basis of accurate three-dimensional geometric feature measurement, biomechanical features are applied to flat valgus
