Description

A kind of torquer for the correction of O-shaped leg

Technical field

The present invention relates to medical instrument more particularly to a kind of O-shaped leg means for correctings.

Background technology

" O " shape leg refers to that double-legged ankle closes up, and double knees cannot be drawn close, and is in " O " font.It is, row too early due to standing mostly Overlong time is walked, caused by lacking the reasons such as nutrition and exercise, causes the convergent force of muscle group and ligament inside and outside large and small leg Amount and stretching, extension strength are uneven.The people of O-shaped leg, due to knee joint varus, body wt is just excessively concentrated on the inside of knee joint and is closed On nodal section.Excessive pressure and frictional force can cause cartilage surface wear on the inside of knee joint, tibial plateau to collapse, and secondary bone closes Section is scorching.To older, it is easy for arthralgia occur, influences normal Ambulatory Activity.The deformity of leg not only influences body Type and bodybuilding also have damage to health.Also the huge psychological pressure thus brought to patient.

The antidote of O-shaped leg includes：Operation, instrument, clamping plate, gaiter, exercise, correction shoe-pad etc..

Operative treatment includes mainly：

1. external fixator adds the inverted U-shaped osteotomy of tibial tubercle.

This method advantage mainly has：Osteotomy is easy to operate, safety, knitting are fast, it is not easy to delayed union occurs, adopt With external fixator convenient for grasping angle when shaping correction, knitting angle can be made accurate, adjustment is also convenient for.Patient was treating For Cheng Zhongke with Go to ground activity, lower limb muscles are not in atrophy.

2. the inverted U-shaped osteotomy of tibial tubercle, postoperative plaster cast is fixed outside.

Nonsurgical correction method includes mainly：

1, clamping plate, this mode of correction of gaiter mode are simple and practicable, and the pressure generated by clamping plate and binding makes at knee joint Ligament be adjusted.Advantage is need not to perform the operation, easy to operate, the disadvantage is that need to adhere to, and clamping plate and binding are easy to make Blood vessel, the nerve of knee joint position cause to damage, and severe patient causes nerve necrosis.

2, instrument correction instrument is also by adjusting lateral ligament in knee joint.The disadvantage is that needing active treatment, root is needed Correction cycle length is determined according to the constitution and perseverance of patient, and the expense than clamping plate, binding is much higher.Advantage is then that can keep away Open the damage to knee joint position blood vessel, nerve.

3, correction shoe-pad is that outside is high, inside is low, in walking, standing, can give shank one strength rotated outward, It can prevent, caused O-shaped leg exacerbation and formation bad because walking appearance.It is easy to use but effective for slight O-shaped leg patient, it is uncomfortable For the O-shaped higher patient of leg degree.

In order to solve the above technical problems, a kind of O-shaped leg means for correcting is applicant provided, which includes holder group Part and torque correction component, bracket component include upper bracket and lower bracket, and the upper bracket is by two pieces of upper backup pads and thigh Support plate is constituted, and medial surface circumferential direction radian and the positive circumference arc of human thigh of thigh support plate match, thigh support The both sides of plate are fixedly connected with two pieces of upper backup pads respectively, and the lower bracket includes knee support plate, leg support Plate and two pieces of lower supporting plates are constituted, medial surface circumferential direction radian and the positive circumference arc of human knee of the knee support plate Match, medial surface circumferential direction radian and the positive circumference arc of human calf of shin support panel match, knee support plate and Shin support panel, which is located at upper and lower sides and is fixedly connected by two pieces of lower supporting plates, to be constituted, the top both sides of the knee support plate It is provided with hinged protrusion, bottom of the hinged protrusion respectively with two pieces of upper backup pads is hinged, and in the handing-over position in left side It is provided with connectiing shaft head, the torque correction component is arranged in connectiing shaft head, and is provided on the left of upper backup pad Gag lever post is provided with lower limit bar on the left of lower supporting plate；The apparatus structure is simple, easy to use, can sustainedly and stably adjust Section corrects shank bending, and pressurization is slow, and soft tissue will not be caused downright bad, and solving children cannot perform the operation since growth is too fast The drawbacks for the treatment of.
