Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bone traction device. Background Technology

[0002] In orthopedic treatment, the Bronx frame is a commonly used traction device. It connects the patient's limbs via traction cables and, with the help of traction force, plays an important role in fracture reduction, dislocation reduction, and maintaining the position after reduction.

[0003] However, existing traction devices can only change the traction angle of the leg by adjusting the position of the patient's leg. But the length of the traction device itself is limited, which directly results in extremely limited space for adjustment of the patient's leg. As a result, the traction device cannot accurately and effectively adjust the traction angle according to the patient's actual condition and physical condition, which greatly affects the treatment effect and the patient's recovery process. Utility Model Content

[0004] The present invention aims to provide a bone traction device to solve the problem that the existing technology cannot effectively adjust the traction angle.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The basic technical solution provided by this utility model is: a bone traction device, comprising...

[0007] A base plate, wherein a first fixed rod is fixedly connected to the base plate, and a first movable rod is slidably connected to the base plate;

[0008] A top plate, wherein a second fixed rod is fixedly connected to the top plate, a second movable rod is slidably connected to the top plate, and an inclined plate is fixedly connected to the top plate;

[0009] A first support rod, with its two sides respectively rotatably connected to a first fixed rod and a second movable rod, and a rotary switch rotatably connected to the first support rod;

[0010] The second support rod is rotatably connected to the second fixed rod and the first movable rod on both sides, and the second support rod is rotatably connected to the first support rod.

[0011] A first threaded rod is threadedly connected to the center of the first movable rod, and one side of the first threaded rod passes through the first fixed rod and is fixedly connected to the rotary switch.

[0012] The first support frame is U-shaped, with its free end penetrating the top plate and being fixedly locked to the top plate by fixing bolts. The first support frame is fixedly connected to a first pulley.

[0013] The second support frame is U-shaped and rotatably connected to the top plate. The second support frame is fixedly connected with a crossbar and a second pulley.

[0014] A fixing component is fitted with a support sleeve, and the support sleeve is threadedly connected to a second threaded rod, the other side of which is rotatably connected to the crossbar.

[0015] The principle of the basic technical solution: The base plate and top plate of the device are the main supporting structures. The base plate is equipped with a fixed first fixed rod and a sliding first movable rod, while the top plate is equipped with a fixed second fixed rod and a sliding second movable rod. The two are rotatably connected by a first support rod and a second support rod. When the rotary switch is rotated, the first threaded rod connected to it rotates accordingly. Since the first threaded rod and the first movable rod are connected by a thread, the first movable rod will be displaced on the base plate. This displacement is transmitted through the rotation of the first and second support rods, causing the top plate and its components to change angle, thereby flexibly adjusting the distance between the base plate and the top plate. In terms of traction function, the first support frame and the second support frame are respectively equipped with a first pulley and a second pulley. The traction rope passes around these pulleys and is connected to the patient's leg, thereby realizing traction on the patient's leg. If the traction angle needs to be adjusted, the first support frame on the top plate can be slid first. After adjusting to the appropriate position, the first support frame can be firmly locked to the top plate using fixing bolts. This allows for precise changes in the traction angle on the patient's leg to meet different treatment needs. By rotating the second threaded rod, the threaded rod and the support sleeve rotate, creating a rotating connection between the second threaded rod and the crossbar. When the second threaded rod and the support sleeve rotate, the distance between the support sleeve and the crossbar is changed, and the support sleeve rotates on the fixing component, causing the second fixing frame to rotate on the top plate. This achieves the rotation of the second support frame.

[0016] The beneficial effects of the basic technical solution are as follows: By rotating the rotary switch to drive the first threaded rod, the first movable rod is displaced. This displacement is transmitted through the first and second support rods, causing the top plate to change its angle and adjusting the distance between the bottom and top plates. It also allows for sliding and fixing of the first support frame, precisely changing the traction angle and achieving flexible, personalized treatment. The first and second pulleys, in conjunction with the traction rope, provide reliable traction, ensuring treatment stability. Rotating the second threaded rod allows the second support frame to rotate, expanding the adjustment methods and angle range, and improving the device's applicability. Furthermore, its operation is simple, using methods such as rotating the switch, sliding the support frame, and rotating the threaded rod, reducing the difficulty of medical and nursing operations, improving treatment efficiency, and comprehensively supporting orthopedic traction treatment.

[0017] Preferably, there are two of each of the first and second support rods, and the two support rods are evenly distributed on both sides of the first threaded rod.

[0018] The above-mentioned settings enhance the structural stability of the device, ensure even stress distribution, and prevent localized damage. Adjusting the traction angle improves precision and stability, allowing the top plate to move smoothly. Furthermore, they distribute stress, reduce wear on support rods, increase device durability, and lower maintenance and replacement costs.

[0019] Preferably, both the bottom plate and the top plate are provided with sliding frames, and the first movable rod and the second movable rod are both disposed within the sliding frames and slidably connected to the sliding frames.

[0020] Through the above design, the sliding frame provides precise guidance for the sliding of the movable rod, ensuring its smooth and linear movement and allowing for more accurate adjustment of the traction angle. Simultaneously, it protects and limits the movable rod, preventing it from detaching due to excessive displacement or accidental force, thus improving the structural stability and safety of the device.

[0028] The base plate 1 has a sliding frame 10, a first fixed rod 101 is fixedly connected to the base plate 1, and a first movable rod 102 is slidably connected to the base plate 1.

[0029] Top plate 2, top plate 2 is provided with sliding frame 10, top plate 2 is fixedly connected with second fixed rod 201, top plate 2 is slidably connected with second movable rod 202, top plate 2 is fixedly connected with inclined plate 203, first movable rod 102 and second movable rod 202 are both provided in sliding frame 10;

[0030] Two first support rods 3 are rotatably connected to the first fixed rod 101 and the second movable rod 202 on both sides of the first support rod 3 respectively, and a rotary switch 31 is rotatably connected to the first support rod 3;

[0031] Two second support rods 4 are provided, with their two sides respectively rotatably connected to the second fixed rod 201 and the first movable rod 102, and the second support rod 4 is rotatably connected to the first support rod 3;

[0032] The first threaded rod 5 is threadedly connected to the center of the first movable rod 102. One side of the first threaded rod 5 passes through the first fixed rod 101 and is fixedly connected to the rotary switch 31. The two first support rods 3 and the two second support rods 4 are evenly distributed on both sides of the first threaded rod 5.

[0033] The first support frame 6 is U-shaped. The free end of the first support frame 6 passes through the top plate 2 and is fixedly locked to the top plate 2 by fixing bolts 601. The first support frame 6 is fixedly connected to the first pulley 602.

[0034] The second support frame 7 is U-shaped and is rotatably connected to the top plate 2. The second support frame 7 is fixedly connected to a crossbar 701 and a second pulley 702.

[0035] The fastener 8 is fitted with a support sleeve 801, and the support sleeve 801 is threadedly connected to a second threaded rod 9. The other side of the second threaded rod 9 is rotatably connected to the crossbar 701.

[0036] The specific implementation process is as follows:

[0037] First, adjust the distance between the base plate 1 and the top plate 2 according to the patient's needs. During the adjustment process, rotate the rotary switch 31 to make the rotary switch 31 rotate with the first fixed rod 101. At the same time, the rotary switch 31 drives the first threaded column 5 to make the threaded column 5 rotate with the first movable rod 102. This causes the first movable rod 102 to slide in the sliding frame 10. In this way, the first fixed rod 101 and the first movable rod 102 cause the first support rod 3 and the second support rod 4 to rotate relative to each other, thereby changing the distance between the base plate 1 and the top plate 2.

[0038] Next, the patient's leg is placed on the top plate 2, and the traction rope connected to the patient's leg is passed around the first pulley 602 and the second pulley 702. At the same time, the traction angle of the traction rope on the patient's leg is adjusted by the device. During the adjustment process, the distance between the first pulley 602 on the first support frame 6 and the top plate 2 is adjusted by sliding the first support frame 6 on the top plate 2. At the same time, the first support frame 6 and the top plate 2 are fixed and locked by the fixing bolt 601, thereby fixing the position of the first pulley 602 and adjusting the traction angle of the traction rope on the patient's leg.

[0039] Finally, the second support frame 7 is rotated. During the rotation, the second threaded column 9 is rotated, causing the threaded column 9 and the support sleeve 801 to rotate, thereby adjusting the distance between the free end of the second threaded column 9 and the support sleeve 801. At the same time, the moving second threaded column 9 rotates with the crossbar 701 on the second support frame 7, thereby adjusting the distance between the crossbar 701 and the support sleeve 801, and causing the second support frame 7 to rotate with the top plate 2.
