Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic postoperative appliances, and particularly relates to an anti-lower limb torsion device for orthopedics after operation. Background Art

[0002] After orthopedic surgery for patients with lower limb fractures, it is usually necessary for the patients to wear a T-shaped shoe. For example, patients with intertrochanteric fractures of the femur, femoral head, femoral neck fractures or combined common peroneal nerve injuries caused by various reasons, and patients after artificial hip joint and artificial femoral head replacement, etc., who need to keep the affected limb in the abduction neutral position, all need to routinely wear a T-shaped shoe to fix the affected limb. The purpose is to keep the affected limb in an abnormal position that can effectively avoid internal rotation and external rotation, and in the abduction neutral position, which can prevent the occurrence of abnormal positions of internal rotation and external rotation after the operation and affect the treatment effect.

[0003] Most of the existing T-shaped shoes are two-piece split type. In the case where both legs of the patient are affected limbs, the patient's feet cannot be limited during use, and the anti-torsion effect on the lower limbs is relatively poor. The patent with the publication number CN 213993877U discloses an anti-lower limb torsion device for orthopedics after operation, including a lower cross plate and an upper cross plate. A number of first clamping blocks are arranged on the lower cross plate, and a number of second clamping blocks are arranged on the upper cross plate. The upper cross plate and the lower cross plate are connected by a number of connecting rods. The heel is clamped between adjacent first clamping blocks on the lower cross plate, and the upper part of the shoe is clamped between adjacent second clamping blocks on the upper cross plate, and the contact surfaces of the first clamping blocks and the second clamping blocks with the shoe are arc surfaces. Although the above patent can limit the feet, it is inconvenient when single-foot limiting is required.

[0004] Therefore, there is an urgent need for an anti-lower limb torsion device for orthopedics after operation that can both limit the feet and facilitate single-foot limiting. Content of the Utility Model

[0005] The utility model provides an anti-lower limb torsion device for orthopedics after operation to solve the problems in the prior art.

[0006] The technical problems solved by the utility model are realized by the following technical solutions:

[0009] A T-shaped shoe part, the T-shaped shoe part is detachably installed on the positioning column frame. The T-shaped shoe part includes a shoe piece and a support frame plate rotatably installed on the back of the shoe piece. Two groups of the support frame plates are provided, and the two groups of the support frame plates are symmetrically arranged on the back of the shoe piece. A sleeve frame for connecting to the positioning column frame is further arranged on the back of the shoe piece.

[0010] In a specific embodiment, the plate base includes a base plate and a vertical plate fixedly arranged on the upper end surface of the base plate. The vertical plate divides the base plate to form a support plate end at the front end of the base plate, and positioning grooves are formed at both ends of the vertical plate.

[0011] In a specific embodiment, the positioning post frame includes a support post fixedly connected to the vertical plate and a guide post fixedly connected to the upper end of the support post.

[0012] In a specific embodiment, the shoe part includes a foot support plate and a magic tape strap fixedly connected to the foot support plate. The foot support plate is of an L-shaped structure, and groove positions for installing the support frame plate are formed on both sides of the back of the foot support plate.

[0013] In a specific embodiment, the support frame plate includes a rod frame and a threaded post inserted and installed at one end of the rod frame. One end of the threaded post is connected in the groove position, and a circular nut is threadedly installed on the threaded post.

[0014] In a specific embodiment, the diameter of the circular nut matches the width of the notch of the positioning groove.

[0015] In a specific embodiment, the sleeve frame includes a sleeve hole block fixedly connected to the back of the foot support plate and a fixing bolt threadedly installed on the sleeve hole block. The sleeve hole block is sleeved on the guide post.

[0016] The beneficial effects of the present utility model are as follows:

[0017] The positioning post frame is fixedly arranged on the plate base, and the shoe part is detachably installed on the positioning post frame through the sleeve frame.

[0033] A positioning frame part 100, the positioning frame part 100 includes a plate seat 110 and a positioning column frame 120 fixedly arranged on the plate seat 110;

[0034] The T-shaped shoe part 200 is detachably installed on the positioning column frame 120. The T-shaped shoe part 200 includes a shoe part 210 and a support frame plate 220 rotatably installed on the back of the shoe part 210. There are two groups of support frame plates 220, and the two groups of support frame plates 220 are symmetrically arranged on the back of the shoe part 210. A sleeve frame 230 for connecting to the positioning column frame 120 is also arranged on the back of the shoe part 210.

[0035] The positioning column frame 120 is fixedly arranged on the plate seat 110. The shoe part 210 is detachably installed on the positioning column frame 120 through the sleeve frame 230. When both legs of the patient are affected limbs, the two shoe parts 210 are respectively installed at both ends of the positioning column frame 120 through the sleeve frame 230 to limit the patient's feet, effectively preventing the lower limbs of the patient from twisting. At the same time, the support frame plate 220 is rotatably installed on the back of the shoe part 210. When one leg of the patient is an affected limb, the corresponding shoe part 210 is removed from the positioning column frame 120, and the support frame plate 220 is opened to be perpendicular to the shoe part 210 for support to limit the affected limb foot of the patient and prevent the lower limbs of the patient from twisting. Compared with the traditional device, this postoperative anti-lower limb torsion device for orthopedics can both limit the feet and is convenient for limiting a single foot.

[0036] As a further preference of the above embodiment, the plate seat 110 includes a base plate 111 and a vertical plate 112 fixedly arranged on the upper end surface of the base plate 111. The vertical plate 112 divides the base plate 111 to form a support plate end 113 at the front end of the base plate 111. The shoe part 210 can be placed on the support plate end 113, and positioning grooves 114 are opened at both ends of the vertical plate 112.

[0037] The positioning column frame 120 includes a support column 121 fixedly connected to the vertical plate 112 and a guide column 122 fixedly connected to the upper end of the support column 121.
