External artificial knee joint-noninvasive correction device for knee joint osteoarthropathy

Abstract

The invention discloses an external artificial knee joint-noninvasive correction device for knee joint osteoarthropathy. The Correction device consists of a shank support, a far-end coupling screw, a regulating system, a near-end coupling screw, a thigh support and a regulating spanner, wherein the regulating system is the core part of the correction device; a worm gear at one end of the regulating system is in fastened connection with the shank support plate of the shank support through the far-end coupling screw; and a rotary plate at the other end of the regulating system is in fastened connection with a thigh support plate on the thigh support through the near-end coupling screw, so that the main body of the correction device is formed; the regulating spanner is sleeved on the worm of the regulating system, the regulating system can change an angle between the shank support and the thigh support of the correction device through rotating the regulating spanner; and furthermore, the change of the angulation of the knee joint is realized, and the knee joint osteoarthropathy correction is completed. The correction device can be used for effectively correcting the knee joint osteoarthropathy, and can also be used for correcting patients suffering from genu varum or genu valgum in real time.

Description

technical field [0001] The invention relates to the field of orthopedic instruments. The invention relates to a device for non-traumatic correction treatment for patients with knee varus and valgus knee osteoarthrosis, in particular to an external artificial knee joint—a non-traumatic knee joint osteoarthrosis correction device. Background technique [0002] Knee osteoarthropathy is a common disease whether primary or secondary, and it is more common in women. Secondary knee osteoarthropathy mostly occurs in genu varus and genu valgus deformity, causing stress concentration, degenerative changes of articular cartilage, meniscus tear, ligament injury, patella softening, chondritis exfoliative, etc. This is due to some problems in the joint capsule, medial collateral ligament (or lateral collateral ligament), inner meniscus (or outer meniscus), cruciate ligament, condylar tibial band, etc., which maintain the stability of the knee joint, and the knee joint loses direction in ...

AI Technical Summary

Problems solved by technology

These operations have certain limitations: there are certain restrictions on body weight, activity level, degree of deformity, degree of lesion, whether there is recent infection, and whether the ligament is normal, etc., and the operation has great mental and economic impact on the patient. pressure

Poor wound healing, infection, joint instability, prosthetic loosening, fracture, common peroneal nerve injury, etc.

So far, there is no ideal artificial prosthesis that can meet the physiological requirements of the normal knee joint in function. Therefore, it is medically recommended that the surgical correction of the artificial knee joint should be strictly controlled.
