Description

Technical Field

[0001] The present application relates to orthopedic instruments, and in particular to an adjustable calcaneal traction support. Background Art

[0002] Tibial and fibula fractures are the most common type of long bone fractures, accounting for about 13.7% of total body fractures. Treatment includes surgical treatment and calcaneal traction. With current traction methods, Kirschner wire displacement is prone to occur during traction, and tilting can cause bleeding at the needle eye, heel compression can cause skin pressure injury, and changes in the traction axis can easily lead to a series of complications such as difficulty in aligning the fracture ends and puncturing the muscles and skin. In addition, when moving the patient, the affected limb is obviously painful because there is no support for traction. Therefore, it is particularly important to improve the innovation of traditional traction and fixation technology. Traditional traction and fixation technology cannot relieve the patient's pain and hinder the role of promoting recovery.

[0003] Traditional traction does not have any supporting brace. It only relies on raising the foot of the bed and placing towels on the left and right Kirschner wires to maintain left and right balance. The affected limb is not fixed, which can easily cause the traction axis to change and make it difficult for the affected limb to remain in a neutral position. The defects of the traditional structure are as follows: 1. There is no support at both ends of the Kirschner wire, which can easily cause the patient's foot to tilt left and right, bleeding at the needle eye, easy change of traction axis, displacement of traction needle, and compression of heel skin by traction arch; 2. There is no suspension at the heel, which can easily cause local skin pressure injury; 3. The affected limb has no support, and it is easy to cause fracture end dislocation and increased pain during transportation; 4. The angle of the traction limb is difficult to adjust, which affects the effectiveness of traction. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will describe the technical solutions in the embodiments of the present invention in detail in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Combination Figure 1-3 As shown, the adjustable calcaneal traction support 100 includes a horizontal support base 101, on which a calf support plate 102 and an ankle support plate 103 are sequentially supported, the bottom of the ankle support plate 103 is horizontally rotated around an axis and installed on a first support block 104, the first support block 104 is vertically movable and installed on a second support block 105, and the second support block 105 is horizontally movable and installed on the horizontal support base 101 along the leg extension direction.

[0021] In this embodiment, the ankle support plate can be rotated and adjusted to a suitable direction, and can be adjusted vertically and horizontally along the leg extension direction through two support blocks to the most comfortable position.

[0022] Furthermore, three spherical slots 106 are formed at the bottom of the calf support plate 102, and three vertical rods 107 are correspondingly arranged on the horizontal support frame 101. A ball head 120 is formed at the top of the vertical rod 107, and the top of the ball head 120 is inserted into the spherical slot 106. The three spherical slots 106 are arranged in a triangle. The bottom of each vertical rod 107 is inserted into a third support block 108, and the third support block 108 is detachably mounted on the horizontal support frame 101 by bolts. A plurality of connecting bolt holes 109 are formed on the horizontal support frame 101.

[0023] In this embodiment, since the two support plates will be stained with blood after use, they are designed to be detachable so that they can be replaced, while the bottom support frame can be retained to reduce loss. At the same time, the direct plug design can be easily connected. At the same time, the connection bolt holes can be selected according to needs, so that the position suitable for the patient can be found and the position can be adjusted according to different patients.

[0024] Furthermore, the calf support plate 102 and the ankle support plate 103 are arc plates respectively made of thermoplastic 3D printing and fitted to the patient.

[0025] In this embodiment, 3D printing is used to select a support plate suitable for the patient. At the same time, because it is easy to get dirty, a disposable one is selected. The support can be directly disposed of after use, while the bottom part is retained for continued use.

[0026] Furthermore, a slot 110 for engaging the Kirschner wire is formed on the top of the ankle support plate 103 .

[0027] In this embodiment, the affected limb is kept in a neutral position.

[0028] Furthermore, a gear 111 is formed at the bottom of the ankle support plate 103, and the gear 111 is rotatably mounted inside the first support block 104. A locking rod 112 is provided on one side of the first support block 104, and the locking rod 112 is rotatably connected to the first support block 104 through a thread, and the head of the locking rod 112 is engaged with the gear 111 to limit the rotation of the ankle support plate 103. A compression spring 113 is sleeved outside the locking rod 112 to keep the locking rod 112 stable.

[0029] In this embodiment, the ankle support plate is rotated and locked, and the position is limited by the locking rod.

[0030] Furthermore, a vertical screw 114 is provided at the bottom of the first support block 104, and vertical guide rods 115 are provided on both sides of the vertical screw 114 at the bottom of the first support block 104. The vertical screw 114 and the vertical guide rod 115 are respectively inserted into the vertical groove 116 formed on the second support block 105, and the middle part of the vertical screw 114 is connected with an adjusting nut 117 through a thread.

[0031] In this embodiment, it can be directly inserted when used, and the nut is rotated at the same time. Due to the limitation of the two vertical guide rods, the vertical guide rod cannot be rotated, so the vertical movement of the vertical guide rod is realized, that is, the vertical movement of the first support block is supported to select a suitable position.

[0032] Furthermore, two horizontal guide rods 118 arranged side by side are formed on the horizontal support frame 101, and the horizontal guide rods 118 are inserted into the second support block 105, and the second support block 105 slides along the horizontal guide rods 118. Locking screws 119 are respectively arranged on both sides of the second support block 105, and the locking screws 119 abut against the horizontal guide rods 118 to limit the sliding of the second support block 105.

[0033] In this embodiment, horizontal movement and locking of the second supporting block are achieved.

[0034] This technical solution:

[0035] 1. Design a calcaneal traction support. The horizontal support frame is made of stainless steel. The stainless steel base has a certain weight and can effectively fix the support on the bed. The calf support plate can ensure the effective fixation of the affected limb. The Kirschner wire slot can balance the Kirschner wire to keep the affected limb in a neutral position.

[0036] 2. The calf support plate is 3D printed with thermoplastic plastic (PLA), which is customized and fits the patient's lower limbs better. The stainless steel base and the calf support plate are designed to be easy to install and remove, so that one person can change it and prevent cross infection.

[0037] 3. The design of the Kirschner wire slot below uses a gear-mounted universal adjustment, which is convenient for rotation and fine-tuning, adjusting the angle of the fracture end, and avoiding the skin fold of the fracture end to cause soft tissue damage and necrosis. The entire slot can be adjusted horizontally and up and down, and three-dimensionally adjusted on the XYZ axis to maintain the fracture alignment and force line. The slot can slide freely forward and backward without affecting the traction force, ensuring the effectiveness of traction, and can also keep the heel suspended, ensuring that it is not compressed, while improving the comfort and safety during use.
