Description

Pediatric clinical leg shape correction device

Technical Field

The utility model relates to the field of medical equipment, specifically relate to device that children's leg type was corrected.

Background

The O-shaped leg is medically known as the knee varus. The deformity disease mainly shows that when the two lower limbs are naturally straightened or stand, the inner ankles of the two feet can collide with each other, and the two knees can not be drawn close. Calcium deficiency and inheritance are two bases for the formation of O-legs, but the more direct cause is walking, standing, sitting and some movements. Children are a group with multiple O-shaped legs, and have a plurality of causes of O-shaped legs of children, such as chondrotrophic disorder and the like, but vitamin D deficiency rickets are more, and hyperhidrosis and easy convulsion are main symptoms at early stage, and if the symptoms are not corrected in time, skeletal development is influenced. When a rickets child grows to about 1 year old and walks in a standing and learning way, legs are difficult to load the weight of the body, and lower limbs are bent towards the outside to form O-shaped legs. In a normal knee joint, the pressure is evenly distributed over the articular surfaces. In the case of the O-leg, the body weight is concentrated on the medial articular surface of the knee joint due to the inversion of the knee joint. Excessive pressure and friction can cause wear of the medial cartilage surface of the knee joint, collapse of the tibial plateau, and secondary osteoarthritis. When the patient is older, joint pain is easy to occur, and normal walking activity is affected.

The utility model with patent number 201020690819.2 discloses a device for correcting the knee varus of a human leg. The utility model comprises an oblique traction device, which is composed of a traction motor arranged in the oblique traction device and an oblique traction cable which is connected with the traction motor and is arranged obliquely; the oblique acting rope is connected with an oblique cross traction bone-setting correction belt which is separately wound by two legs. The utility model discloses mainly to the rotary displacement of knee joint, take the rotatory aversion of mechanically-drawn mode to the knee joint to correct. The utility model discloses a slant draw gear and the orthopedic area that corrects that use play and correct the displacement of low limbs joint, the effect of treatment genu varum. This patent is designed without consideration of the need for leg correction to correct both the foot and leg simultaneously, and has certain limitations. The invention with the patent number of 201810262229.0 discloses a pediatrics O-shaped leg correction device, which comprises a base plate, wherein a bottom plate is fixed on the bottom surface of the left end of the base plate, a sliding groove is formed in the upper surface of the bottom plate, a clamping plate which is in sliding connection with the sliding groove is arranged in the sliding groove, a first electric telescopic rod in the horizontal direction is installed at the lower end of the middle part of the base plate, the pediatrics O-shaped leg correction device is simple in structure, the wrists of a patient are bound and fixed through a binding band, the knee joints of the patient are adjusted through two clamping plates, so that the O-shaped leg correction effect is achieved, the highland barley inversion caused by the O-shaped legs is adjusted through the feet, the folding of the knee joints is assisted, the arrangement of an inclined pressure pad avoids the separation of the legs from the whole body when the feet are turned over, a child can finish correction treatment under the sitting posture condition, the, the correction effect is good, and the recovery of the infant patient is accelerated. The device need carry out long-time constraint to the shank when proofreading children's shank, leads to shank paralysis easily for a long time, is difficult for using for a long time. Patent No. 201810326552.X discloses an O-shaped leg orthosis that is compact and can quickly begin effective training. The O-shaped leg correction device is provided with: a pair of left and right foot-rest sections on which the user's feet are placed from the upper surface side; and a rotating part fixed on the pedal part and at least one part of which protrudes from the lower surface side of the pedal part, wherein the rotating part comprises: a fixing part fixed on the pedal part; and a shaft portion which is rotatably engaged with the fixed portion, has a ground contact surface which is in contact with a ground at a position protruding from a bottom surface of the step portion, and extends in a vertical direction, and when the rotating portion is rotated in a predetermined direction about the shaft portion, a force is generated in the fixed portion fixed to the step portion to return in a direction opposite to the predetermined direction. This patent corrects for the O-leg by designing an adjustable foot pedal, but the device also does not correct for the patient's leg and the shape of the leg returns to its original shape before the correction device is used some time after the patient is removed from the orthosis.

The prior O-shaped leg correction device can not achieve the aim of correcting feet and legs simultaneously, and can bring certain fear to children due to long-time constraint correction, thereby reducing the using effect of the device.

Disclosure of Invention

An object of the utility model is to provide a pediatrics leg type orthotic devices can reach the purpose of proofreading and correct foot and shank simultaneously.
