Technical Field

The utility model relates to the technical field of medical care devices, in particular to an appliance for stretching knee joints.

Background

The knee joint is composed of the lower end of femur, the upper end of tibia and patella, is the most complex joint of human body, and belongs to the pulley joint. There is currently an increasing trend in the incidence of conditions caused by deformation at the knee joint, for example: the knee joint is narrow, the meniscus is damaged or shifted rapidly and chronically, the upper and lower contact surface force points of the knee joint are wrong to cause pain, the tibial tuberosity or the femoral tuberosity surface is flat and fractured to shift, and the ligament tendon around the knee joint is rapidly and chronically strained, the knee joint is everted or everted to cause O-shaped leg or X-shaped leg, chronic pain is caused, a patient cannot walk when the disease is serious, and a plurality of inconveniences are brought to life and work. If the diseases are treated by medicaments, the general curative effect is slower and the recovery time is long; if the treatment is performed by means of surgery, the effect is mostly dependent on the experience of doctors, and the treatment is usually expensive, and adverse effects such as postoperative infection can also occur. In addition, most of the conventional knee joint correcting devices are focused on solving the problem of how to restore the knee joint to its bent state, but the above-mentioned cases of serious knee joint deformation cannot be improved by such correction, and the conventional correcting devices have a certain effect on relief of symptoms and have unsatisfactory effects.

Disclosure of Invention

The present utility model aims to provide an orthosis for knee extension, which solves the problems set forth in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the corrector for knee joint stretching comprises a shell, wherein a cover plate is fixedly arranged above the shell, and a fixing plate is fixedly arranged at one end of the cover plate;

a connecting rotating block is rotatably arranged on one side, far away from the fixed plate, of the shell, the connecting rotating block is connected with a screw rod, the screw rod is rotatably arranged inside the shell, and a rotating handle is connected to the outer side of the connecting rotating block;

the screw rod is provided with a screw nut in a threaded fit manner, the screw nut is fixedly provided with a movable plate, and the movable plate is arranged above the cover plate.

Preferably, both ends of the screw rod are mounted at both ends of the shell through bearings.

Preferably, the cover plate is provided with long grooves for the movable plate to move under the action of the movable plate, and the two long grooves are symmetrically arranged.

Preferably, the fixing plate and the movable plate are provided with fixing strip holes for fixing the legs.

The beneficial effects are that: compared with the prior art, the utility model has the beneficial effects that: through the mutually supporting use between fixed plate, fly leaf, the lead screw etc. that set up, the user uses on fixed plate and fly leaf through fixing the leg, and manual rotation rotates the handle and can effectually carry out tensile treatment to the knee joint of shank to the convenience patient uses to the use simple, the operation of being convenient for.
