Description

Three-dimensional traction device for knee joint

Technical Field

The utility model relates to a knee joint three-dimensional traction device, and belongs to the technical field of medical bone fracture rehabilitation equipment.

Background

Senile osteoarthritis is characterized in that due to pathological changes of bones and periosteum per se and increase of intraosseous pressure caused by long-term mechanical trauma, load bearing or inflammation, on one hand, joint progressive destruction is caused, on the other hand, joint marginal hyperosteogeny, osteophyte formation and joint cavity are reduced, intraosseous pressure is further increased, venous reflux disorder is caused, arterial blood perfusion in bones is influenced, oxygen supply is insufficient, secretion removal is delayed, metabolism is slowed down, cartilage damage is accelerated, the early stage often starts from invasion of gaps on one side of a knee joint, and varus or valgus deformity is formed in a long time with more insides and longer time, and tibiofemoral joint dislocation is formed, the abnormal force lines of the knee joint caused by the multiple introversion can aggravate the tension of the muscle-tendon complex around the joint, the load is increased during the joint movement, the balanced transmission cannot be realized, and the pump-like effect of the joint cartilage cannot be normally realized, thereby aggravating the cartilage damage.

There are many treatment methods at home and abroad, and the treatment for the diseases generally adopts plaster application, massage physical therapy or oral medicines for treatment, but the treatment effect of most patients adopting the treatment is easy to repeat, the operation treatment cost is high, the long-term effect is not ideal, inconvenience is caused, and the repetition is also generated, so that many patients with symptoms which are not particularly serious are forbidden.

The existing knee joint retractor comprises a spring type, an electric type and a weight type, and the main defects and the defects are that:

1. the traction direction is single: most of the existing instruments are longitudinal axis traction (Y axis), the knee malformed joint of a human body is three-dimensional, and the traction force in a single direction hardly plays a comprehensive correcting effect. The possible reason is that the professional understanding of the knee joint osteopathy and arthropathy of the human body is not enough, and the deformed knee joint can be comprehensively corrected only by one-side traction which considers that the longitudinal axis is in one direction, and the three-dimensional structure of the knee joint and the mechanical characteristics of the deformity are not comprehensively considered.

2. Lack of corrective effect: the prior art of the instruments focuses on traction, joint gaps are increased through traction, and the knee joint deformity cannot be effectively solved through traction, especially single longitudinal axis direction traction is not enough, and the knee joint correction effect is not enough. The reason is probably that the traction and the correction are mixed, the traction is considered to be correction in a one-sided way, and the correction is realized by the traction, so that only the traction is enough for the knee joint deformity, which is a very one-sided idea that the deformed knee joint can effectively recover the original force line by special correction, for example, the knee joint deformity of the human body occurs on the frontal axis (X axis), inwards or outwards, and the correction effect can be really realized only by applying opposite force on the frontal axis (X axis), otherwise, the main problem is not caught, the effect is little, and even the southern thill is rutted.

3. Lack of joint angle adjustment function: the existing appliance technology lacks the setting functions of the initial angle of the knee joint and the traction angle in the traction process, and the direct full-angle range traction causes the pain of the deformed knee joint to be aggravated, thereby seriously affecting the traction effect. The possible reasons are that the lack of clinical practice experience and the lack of listening advice of the patient cannot take into account the psychological feeling and bearing degree of the patient, the knee joint deformity, the contracture of the soft group, the adhesion, the direct full-angle traction, the severe pain can be generated, the patient can hardly bear the pain, even if the pain is strongly tolerated, the deformed knee joint can flex and contract to resist with the traction equipment due to the human body self-protection consciousness and the body stretch reflex reflection, the traction and correction effect is hardly played, and the great effort is half.

In summary, the existing knee joint traction equipment has the defects and shortcomings of single traction direction, lack of correction effect, lack of joint angle adjustment function and the like.
