Description

A kind of patella loosener

technical field

The invention relates to the technical field of knee joint treatment, in particular to a patella loosener.

Background technique

There are more and more operations after knee joint injury, and the subsequent "knee joint adhesion" causes serious dysfunction in patients. How to prevent "knee joint adhesion" in the early stage is placed in front of orthopedic surgeons and rehabilitation workers.

The current clinical way to prevent knee joint adhesions is the continuous passive joint trainer (CPM) of the knee joint. The invention of the knee joint CPM reduces the workload of the treatment staff. Long-term passive activities can prevent some problems of knee joint adhesions in patients, but it is not comprehensive enough. ;Due to the ineffective contraction of the quadriceps muscle in the early postoperative period, resulting in patellofemoral joint adhesion and contracture of ligaments and tendons around the patella, knee joint CPM cannot effectively prevent patellofemoral joint adhesion; prevention of patellofemoral joint adhesion and soft tissue contracture around the patella At present, the current clinical treatment method is artificial patellar mobilization, but it is labor-intensive, unsustainable, short-term, and insufficient in curative effect. Artificial loosening generally only loosens in 4 directions, and the loosening intensity and frequency are not accurate enough. It depends on the subjective feelings of the treating personnel and cannot be standardized , so it is necessary to design a patella loosener to solve the above problems.
