[0028] In the above description of the utility model, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0029] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.
[0030] See also Figure 1-7 The utility model provides a technical solution: a traction device for a lower leg fracture, comprising a first Kirschner wire 1, a second Kirschner wire 2, a connecting rod assembly and a supporting portion, wherein the first Kirschner wire 1 is used to penetrate the position of the patient's lower leg corresponding to the tibial tubercle along the left and right directions, and the second Kirschner wire 2 is used to penetrate the position of the patient's foot corresponding to the calcaneus along the left and right directions. There are two connecting rod assemblies, and the two connecting rod assemblies are respectively located on the left and right sides of the patient's lower leg. There are two supporting portions, and the two supporting portions are respectively arranged on the two connecting rod assemblies. The two supporting portions are respectively used to support the left and right sides of the patient's lower leg. The two ends of the connecting rod assembly are respectively used to be fixedly connected with the first Kirschner wire 1 and the second Kirschner wire 2, and the connecting rod assembly is also used to push the first Kirschner wire 1 and the second Kirschner wire 2 in opposite directions.
[0031] When using the calf fracture traction device described in the utility model, the first Kirschner wire 1 is made to penetrate the patient's calf in the left-right direction at the position corresponding to the tibial tubercle, and the second Kirschner wire 2 is made to penetrate the patient's foot in the left-right direction at the position corresponding to the calcaneus. Then the two connecting rod assemblies are respectively placed on the left and right sides of the patient's calf, so that the two ends of the connecting rod assembly are respectively fixed to the first Kirschner wire 1 and the second Kirschner wire 2, and the connecting rod assembly pushes the first Kirschner wire 1 and the second Kirschner wire 2 in opposite directions. Under the pushing action of the connecting rod assembly, the first Kirschner wire 1 and the second Kirschner wire 2 can respectively provide forces in opposite directions to the patient's calf, and the calf fracture traction device described in the utility model can pull the patient's calf to stretch the fracture position of the patient's calf. Finally, the two supporting parts respectively arranged on the two connecting rod assemblies respectively support the left and right sides of the patient's calf. Under the restriction of the supporting parts, the two connecting rod assemblies are not easy to move left and right, so that the first Kirschner wire 1 is not easy to move left and right relative to the patient's calf, and the second Kirschner wire 2 is not easy to move left and right relative to the patient's foot, which can reduce the patient's pain.
[0032] In this embodiment, the supporting portion includes two supporting components, both of which are arranged on the connecting rod component, and the two supporting components are used to alternately support the patient's calf.
[0033] When the abutting part abuts against the patient's calf, the two abutting components can abut against the patient's calf alternately. The two abutting components abut different positions on the patient's calf respectively, so that the positions on the patient's calf corresponding to the two abutting components can be abutted alternately, which can prevent a certain position on the patient's calf from being subjected to pressure damage due to long-term pressure from the abutting part, and can reduce the possibility of pressure damage to the patient's calf.
[0034] In this embodiment, the supporting assembly includes a mounting plate 3, a first screw hole, a screw rod 4 and a supporting plate. The mounting plate 3 is fixed on the connecting rod assembly. The first screw hole is provided on the mounting plate 3 and is arranged along the left and right directions. The screw rod 4 is screwed into the first screw hole. The supporting plate is rotatably connected to one end of the screw rod 4 facing the patient's calf.
[0035] The screw rod 4 is rotated in the first screw hole to move toward the patient's calf, and the abutment plate moves toward the patient's calf along with the screw rod 4 until the abutment plate abuts against the patient's calf, and then the screw rod 4 is stopped from rotating. With this structure, the abutment assembly can abut against the patient's calf, which is very convenient when abutting against the patient's calf.
[0036] The screw rod 4 is rotated in the first screw hole to move the screw rod 4 away from the patient's calf. The support plate moves with the screw rod 4 away from the patient's calf, and the support plate can be separated from the patient's calf, thereby releasing the support of the support component on the patient's calf.
[0037] The abutment plate is rotatably connected to the screw rod 4, and when the screw rod 4 rotates, the abutment plate cannot be driven to rotate. After the abutment plate contacts the patient's calf skin, the abutment plate will not scratch the patient's skin due to rotation, which can reduce the possibility of the patient's calf skin being scratched by the abutment plate.
[0038] In this embodiment, the supporting assembly also includes a ring 5 and a bearing 6. The ring 5 is fixed on the supporting plate, and the bearing 6 is fixed on the ring 5. The outer ring of the bearing 6 is welded and fixed to the ring 5, and the end of the screw 4 facing the patient's calf is fixed in the bearing hole of the bearing 6.
[0039] The inner ring of the bearing 6 can rotate relative to the outer ring of the bearing 6, the outer ring of the bearing 6 is fixedly connected to the abutment plate through the ring 5, and the inner ring of the bearing 6 is fixedly connected to the end of the screw rod 4 facing the patient's calf. With this structure, the abutment plate can be rotatably connected to the end of the screw rod 4 facing the patient's calf.
[0040] In this embodiment, the support plate includes a rigid plate body 7 and a soft elastic rubber pad 8. The rigid plate body 7 can be a metal plate or a plastic plate. The rigid plate body 7 can be rotatably connected to the end of the screw rod 4 facing the patient's calf. Specifically, the ring 5 is fixed on the rigid plate body 7, and the rigid plate body 7 can be rotatably connected to the end of the screw rod 4 facing the patient's calf. The soft elastic rubber pad 8 is fixed on the side of the rigid plate body 7 facing the patient's calf. A plurality of first air holes 9 are formed on the rigid plate body 7. The first air holes 9 vertically penetrate the two side surfaces of the rigid plate body 7. Second air holes 10 are formed on the soft elastic rubber pad 8 at the position corresponding to each of the first air holes 9. The second air holes 10 vertically penetrate the two side surfaces of the soft elastic rubber pad 8.
[0041] When the abutment plate abuts against the patient's calf, the soft elastic rubber pad 8 contacts the patient's calf skin, which can improve the comfort of use of the calf fracture traction device of the utility model. By providing a plurality of the first air holes 9 on the rigid plate body 7 and a plurality of the second air holes 10 on the soft elastic rubber pad 8, the ventilation effect of the abutment plate can be improved, which can further improve the comfort of use of the calf fracture traction device of the utility model.
