Technical Field

[0001] The utility model relates to the technical field of traction frames, in particular to an orthopedic traction frame. Background Technique

[0002] A fracture refers to the complete or partial rupture of the continuity of bone structure. It is more common in children and the elderly, and also often occurs in young and middle-aged people. Patients usually have a fracture in one part, and a few have multiple fractures. With timely and appropriate treatment, most patients can recover their original functions, and a few patients may have different degrees of sequelae left;

[0003] If a patient has a lower limb fracture, such as intertrochanteric fracture of the femur, femoral shaft fracture, tibiofibular fracture, etc., surgical treatment is required; before the operation day after the patient is admitted to the hospital, lower limb traction and braking are often required; before a patient with a lower limb fracture enters the hospital for surgery, traction of the broken limb is required. However, the current traction frame can only be fixed on the hospital bed. When using this kind of traction frame, due to the different lower limb lengths and lifting heights of different patients, the position of the supporting plate of the traction frame needs to be adjusted, and after adjustment, the position of the adjusted supporting plate needs to be fixed, which affects its convenience in use; therefore, the above problems need to be improved. Summary of the Invention

[0004] The technical problem to be solved by the utility model is that: before a patient with a lower limb fracture enters the hospital for surgery, traction of the broken limb is required. However, the current traction frame can only be fixed on the hospital bed. When using this kind of traction frame, due to the different lower limb lengths and lifting heights of different patients, the position of the supporting plate of the traction frame needs to be adjusted, and after adjustment, the position of the adjusted supporting plate needs to be fixed, which affects its convenience in use; therefore, the above problems need to be improved.

[0005] To solve the above problems, the technical solution adopted by the utility model is: an orthopedic traction frame, including a detection table and cross frames arranged at the front and rear ends above the lower limb supporting part of the detection table. Fixed cylinders are arranged on the top surface of the detection table below both sides of the bottom surface of the cross frame. A rectangular cavity is opened inside the fixed cylinder, and a lifting rod with its top end fixedly connected to the bottom of the cross frame is arranged inside the rectangular cavity. One end of each of the two cross frames is slidably clamped with a U-shaped moving seat. A supporting rod is longitudinally fixedly connected to the inner end surface of the moving seat. A plurality of threaded grooves are longitudinally equidistantly opened at the top of the supporting rod. A support rod is vertically threadedly connected inside the threaded groove. A supporting arc plate for lower limb support is installed at the top end of the support rod; adjustment cavities are respectively opened inside the front and rear ends of the tail of the detection table, and a transmission component for lifting and adjusting the lifting rod is arranged inside the adjustment cavity.

[0006] The beneficial effects of the utility model are as follows: through the cooperation of the transmission component with the cross frame and the arc supporting plate, the arc supporting plate can be adjusted according to different use heights, and the two arc supporting plates for supporting the lower limbs can be adjusted to different heights; and after the arc supporting plate is adjusted, its height can be automatically locked and fixed, which greatly improves the convenience of the device when in use.

[0007] The utility model further improves the technical solution adopted as follows: the transmission assembly includes a threaded rod vertically rotatably arranged on the bottom surface of the rectangular cavity, a transmission shaft rotatably arranged inside the transmission cavity, and a worm vertically rotatably arranged inside the transmission cavity; a worm wheel meshing with the worm is fixedly sleeved on the transmission shaft, and the bottom end of the worm movably passes through the outside of the transmission cavity and is fixedly connected to a handwheel; active bevel teeth are fixedly sleeved at both ends of the transmission shaft, the bottom end of the threaded rod movably passes through the interior of the transmission cavity, and is fixedly connected to a driven bevel tooth meshing with the active bevel teeth; the bottom end of the lifting rod extends into the interior of the rectangular cavity and is sleeved with a limiting plate; the bottom end surface of the lifting rod is provided with a threaded hole for the threaded rod to extend into.

[0008] The beneficial effects of the above improvements are as follows: through the setting of the transmission assembly, the worm can be driven to rotate by turning the hand wheel, and the engagement of the worm and the worm wheel can facilitate the rotation of the transmission shaft. When the transmission shaft rotates, the active bevel gear and the driven bevel gear can cooperate to drive the threaded rod to rotate synchronously, thereby achieving a synchronous lifting and lowering effect on the lifting rod, thereby adjusting the height of the cross frame, and thereby adjusting the height of the arc support plate on the supporting rod, and the heights of the two arc support plates can be adjusted asynchronously.

[0009] As a further improvement of the utility model, the technical problem to be solved is: if the movable seat card is only arranged on the horizontal frame, it will be inconvenient to position it.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: a threaded hole is opened on the bottom surface of the movable seat, a positioning bolt is arranged inside the threaded hole, a positioning groove is opened horizontally on the top of the cross frame, and a plurality of positioning holes cooperating with the positioning bolts are opened equidistantly on the bottom surface of the positioning groove; a storage cavity is opened in the upper part of the movable seat, and a guide component for preventing the movable seat from deviating is arranged inside the storage cavity.

[0011] The beneficial effect of the above improvement is that the movable seat can be easily fixed in a limited position through the cooperation between the positioning groove and the positioning bolt.

[0012] As a further improvement of the utility model, the technical problem to be solved is: if the upper part of the moving seat is simply clamped on the cross frame, when the moving seat is loaded, it will be separated from the cross frame, and the stability of the moving seat moving on the cross frame will be affected.

[0013] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the guide assembly includes a positioning block movably arranged inside the storage cavity, an anti-slip plate arranged on the top of the positioning block and a thrust spring arranged on the top of the anti-slip plate; the bottom end of the positioning block movably passes through the outside of the storage cavity, and the positioning block is inserted into the positioning groove of the cross frame.

[0014] The beneficial effect of the above improvement is: through the setting of the guide component, it is convenient to guide the moving seat during the movement process, which can avoid the upper part of the moving seat stuck on the cross frame being separated from the cross frame when loaded, and improve the stability and efficiency of the connection between the moving seat and the cross frame.

[0015] As a further improvement of the utility model, the technical problem to be solved is: if the surface of the arc support plate is smooth, the ventilation effect of the supporting part will be affected when the lower limbs are supported for a long time.

[0016] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the outer side surface of the bottom end of the positioning block is inclined, and a layer of breathable cotton pad is provided on the inner arc surface of the arc supporting plate.

[0017] The beneficial effect of the above improvement is: by providing a breathable cotton pad, it is convenient to avoid the contact between the skin of the supported lower limb and the arc support plate, thereby improving the breathability of the arc support plate during support.

[0018] As a further improvement of the present invention, the technical problem to be solved is: if the arc supporting plate and the support rod are rigidly connected, it will be inconvenient to adjust the supporting angle of the arc supporting plate.

[0019] In order to solve the above technical problems, the utility model further improves and adopts a technical solution as follows: a ball head universal joint connected to the arc support plate is installed at the top end of the support rod.

[0020] The beneficial effect of the above improvement is that by setting a ball head universal joint, the angle of the arc support plate at the top end of the support rod can be adjusted easily, thereby improving the application range of supporting the lower limbs.
