Description

O-shaped leg correction device

Technical Field

The utility model relates to a knee joint correction technical field especially relates to a O type leg orthotic devices.

Background

The type 0 leg is a common defect of leg deformity in children and teenagers, the forming factors of the O-shaped leg are very complex, and the following reasons exist commonly: first, genetic factors, some patients, are inherited because of O-leg deformities in the previous generation. Secondly, the development reason is more common that the development reason is that in the process of body development, due to the deficiency of trace elements such as calcium, phosphorus and the like, the abnormal development of bones is caused, and finally, the deformation of bone is caused, and the O-shaped leg deformity is formed. Further, there is a possibility that the formation of the O-leg may be caused by a long-term bad posture or an improper exertion habit, the imbalance of the muscle strength on both sides is caused, and finally the medial traction force is excessively large, thereby causing the formation of the O-leg in the knee joint. In addition, there are also a few, less common, O-leg deformities due to injuries to the knee joint, such as medial collapse of the tibial plateau, injury to the medial collateral ligament, and the like. The type 0 leg has very good influence on beauty and certain influence on health, which may cause the abrasion of the cartilage surface at the inner side of the knee joint, the collapse of the tibial plateau and secondary osteoarthritis, and may also bring about bad psychological problems such as inferior quality and the like for patients.

The existing correction method for the O-shaped leg comprises two modes of surgical correction and non-surgical correction. The surgical method is suitable for more serious patients, and has quick response, but higher cost and higher risk. At present, the correction brace on the market utilizes night sleep time usually, bind with cloth bandage etc. by force, correct, this kind of orthotic devices is time, the limitation in space, the travelling comfort is poor, very influence patient's daily life, and when not walking according to the human body, the relative position of limbs comes corresponding project organization, long-time result of use is not ideal, consequently, how to design one kind can daily dress, guarantee certain normal activity, correct effectual O type leg orthotic devices, become further improved direction.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 2, an O-shaped leg correction device includes a bending support rod 1, a leg fixing structure 2, a floor support point structure 3 and a foot placing plate 4, the bending support rod 1 is an L-shaped rod structure, the bending support rod 1 includes an inclined upright rod portion 11 and a bottom rod portion 12, the inclined upright rod portion 11 and the bottom rod portion 12 are movably connected, a limit hole is formed at the bottom of the inclined upright rod portion 11, an articulated shaft 13 is fixedly arranged at an end portion of the bottom rod portion 12 close to the inclined upright rod portion 11, the articulated shaft 13 is inserted into the limit hole, and an end portion of the articulated shaft 13 is fixed by a bolt, so that the inclined upright rod portion 11 can swing at a certain angle relative to the bottom rod portion 12, and the forward and backward swinging is for solving the angle change of a lower leg and a sole, and is matched with the limb movement when a person walks, and accords with ergonomics. Shank fixed knot constructs 2 and passes through the upper portion that the screw fixation set up in slope pole portion 11, and shank fixed knot constructs 2 and includes enclosing plywood 21 and thread gluing area 22, and thread gluing area 22 both ends articulate respectively at enclosing plywood 21 both ends.

In addition, the distance between the articulated shaft and the foot placing plate 4 is 8 cm, which is exactly the approximate position of ankle movement, and accords with the human engineering.

The sole portion 12 is kept away from the tip of slope pole portion 11 and is installed and put sole 4, and the concrete fixed mode is, has evenly seted up a plurality of mounting holes on the sole portion 12, puts the foot board 4 through screw demountable installation in the corresponding mounting hole of sole portion 12, puts and is provided with the bandage 41 that is used for fixed foot on the foot board 44, and the bandage 41 divide into the vamp bandage 411 that is used for fixed instep and the ankle bandage 412 that is used for fixed ankle, can realize well the foot with putting the foot board 44 and fix.

Bottom pole portion 12 is close to the bottom surface of slope pole portion and is provided with the fulcrum structure 3 that falls to the ground, and the fulcrum structure 3 that falls to the ground passes through screw demountable installation in the mounting hole, falls to the ground 3 lower surfaces of fulcrum structure and ground butt, and the fulcrum structure 3 that falls to the ground can bear elastic deformation, guarantees that the lower surface can contact with ground better to safety and stability more when people use this orthotic devices.

Overall structure makes human focus move outward, passes through the inward power of correcting of structure increase shank with self weight, specifically, the utility model discloses the theory of operation is as follows, because the reason of people's gravity has a decurrent power to the one end of sill bar portion 13, it is known as the fulcrum of sill bar portion 13 to fall to the ground fulcrum structure 3, people's gravity has an ascending power to the other end of sill bar portion 13, ascending power acts on shank fixed knot through bending bracing piece 1 and constructs 2, make a concerted effort and act on the knee joint outside along shank fixed knot structure 2, in order to reach the effect of stretching the inboard ligament of knee joint, and as long as possible, the ligament outside of knee joint resumes, shortens, the ligament of knee joint is elongated to the inboard, resumes, in order to reach the effect of correcting O type leg.

Finally, it should be noted that: the above embodiments are merely illustrative of the technical solutions of the present invention, and not limitative thereof; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
