Description
Technical field
The present invention relates to joint replacement field, in particular to a kind of soft tissue device for measuring force.
Background technology
As one of major joint displacement, total knee arthroplasty is a ripe operation, total knee arthroplasty
Success or not and the Study on influencing factors to clinical efficacy, problem the most of concern.The treatment clinical at a specified future date obtained
Effect, the management accurate, preoperative selected, operation skill for the selection of indication, prosthese is the most critically important, especially the biggest
Requirement to operation skill in degree, accurate osteotomy, prosthese solid should put on three dimensions, it is also noted that bends and stretches knee joint and closes
The soft tissue balance such as gap and ligament during joint, stable, it is ensured that the set of femur, tibia and patellar prosthesis parts is accurate.
After completing sclerotin cutting, it is flat that whole replacement advances to a step the most crucial, i.e. knee joint week soft tissue
Weighing apparatus, this is also a step of difficulty the most, unlike cutting osseous tissue, has good supporting apparatus that doctor can be helped to position, measure
And correction, soft tissue balance still relies more heavily on experience and the technology of doctor, processes the most proper, directly affects postoperative ankle merit
Energy and stability.In order to obtain more preferable Long-term effect, the accuracy of soft tissue balance is that people constantly explore and pursue
Target.
In conventional total knee replacement carries out marrow by mechanical guiding device, marrow outside fix osteotomy, patient by naked eyes,
Feel and experience position anatomic landmark, the lower limb line of force and prosthese rotation axis, and then manual line osteotomy, prosthese are placed and soft
Structural equation, unlike cutting osseous tissue, has good supporting apparatus that doctor can be helped to position, measure and correct, and soft tissue is put down
Weighing apparatus still relies more heavily on experience and the technology of doctor.This soft tissue balance completed based on naked eyes, feel and experience has very
Big subjectivity, processes the most proper, directly affects postoperative function of joint and stability.
Although people constantly improve the mechanical positioning function of traditional operation apparatus, improve the accuracy of Using prosthesis, but do not have
Have and provide corresponding apparatus for soft tissue balance.Therefore, the soft tissue balance accuracy in traditional surgical approaches is largely
Depend on the subjective judgment of patient.
