DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0031] The present application provides an orthopedic traction frame, which is mainly used to solve the problem that some existing traction frames are arranged on a frame body through a traction rope, one end of which is connected to a hanging ring for hanging the patient's lower limbs, and the other end of which is hung with a corresponding counterweight to achieve the traction effect. However, different patients have different body shapes, and different counterweights need to be installed for different patients. In addition, the traction frame is generally movable, and it is necessary to carry counterweights of various specifications when moving, which is troublesome and has a poor use effect. The following technical solutions are provided, which will be combined with Figure 1-Figure 6 Make a detailed description:

[0032] An orthopedic traction frame mainly includes a mounting frame 1 and a clamping and fixing assembly 2 and a traction assembly 3 mounted on the mounting frame 1. The traction frame is designed to provide a traction solution that meets the needs of different patients, while simplifying the operation process and improving the convenience of use. The specific implementation is as follows:

[0033] The clamping and fixing component 2 is used to clamp and fix the mounting frame 1 on the bedside of the hospital bed. The clamping and fixing component 2 can firmly clamp the mounting frame 1 on the bedside of the hospital bed through its structural design, thereby ensuring the stability and safety of the traction frame during use;

[0034] The traction assembly 3 includes a pulley 31, a traction rope 32, a hanging part 33 and an adjustable elastic stretching part 34. The number of the pulley 31 is not less than one and is rotatably mounted on the mounting frame 1. The traction rope 32 is wound around the pulley 31 to ensure smooth sliding of the traction rope 32. The hanging part 33 is installed at one end of the traction rope 32 and is used to hang the patient's lower limbs. The elastic stretching part 34 is installed on the mounting frame 1 and connected to the other end of the traction rope 32. The size of the gravity borne by the hanging part 33 can be changed by adjusting the elastic stretching part 34.

[0035] When the device is used in specific operations, the medical staff can first fix the mounting frame 1 to the bedside by clamping the fixing component 2, so as to facilitate the traction treatment. Then the elastic stretching part 34 is adjusted, and finally the patient's lower limbs are hung on the hanging part 33 to perform traction treatment on the patient's lower limbs.

[0036] Through the adjustment of the elastic stretching part 34, the traction frame of the device can provide personalized traction force without replacing the counterweight, which simplifies clinical operation. The design of the traction component 3 makes the traction frame more convenient to move, without the need to carry counterweights of various specifications, thus reducing the workload of medical staff.

[0037] For details, please refer to Figure 2-Figure 6 A vertical slide groove 11 is constructed on the mounting frame 1, and a vertical stabilizing rod 12 is connected between two inner walls opposite to each other of the slide groove 11. The elastic stretching portion 34 includes two adjustment plates 341 that slide in the slide groove 11 and are movably mounted on the stabilizing rod 12, ensuring the accuracy and reliability of traction adjustment. A spring 342 is connected between the two adjustment plates 341, and the spring 342 is always in a stretched state. A blocking block 343 located between the two adjustment plates 341 is fixed on the inner wall of the slide groove 11. The function of the blocking block 343 is to limit the upper adjustment plate 341. A threaded plug is provided on the mounting frame 1. There is a vertical threaded rod 344, the top end of the threaded rod 344 is rotatably mounted on the adjusting plate 341 located below, and the other end of the traction rope 32 is connected to the adjusting plate 341 located above. When the elastic stretching part 34 is specifically adjusted, the blocking block 343 limits the upper adjusting plate 341, and the movement of the lower adjusting plate 341 is controlled by rotating the threaded rod 344, thereby changing the length of the spring 342. When the length of the spring 342 becomes shorter, the gravity borne by the suspension part 33 becomes smaller, and when the length of the spring 342 becomes longer, the gravity borne by the suspension part 33 becomes larger, thereby meeting the treatment needs of different patients;

[0038] The cooperation between the slide groove 11 and the stabilizing rod 12, and the continuous stretching state of the spring 342, ensure that the traction force can be accurately adjusted. The use of the stabilizing rod 12 improves the structural stability of the traction frame, ensures the stable operation of the two adjustment plates 341, and reduces the potential risks during the treatment process. Through the adjustment mechanism of the elastic stretching part 34, the traction frame can adapt to the needs of different patients, thereby improving the adaptability and effectiveness of traction treatment.

[0039] In this embodiment, a scale line is set on one side of the mounting frame 1, and the scale line corresponds to the adjustment plate 341 below. The scale line can be used to quickly know the bearing capacity of the suspension part 33. It should be noted that the scale line is not marked in the drawings in this scheme. The scale marking is an existing mature technology and will not be repeated here.

[0040] For further information, see Figure 2 , Figure 4 and Figure 6The hanging part 33 includes a U-shaped rod 331 fixed on one end of the traction rope 32 and opening downward, and an arc-shaped plate 332 opening upward is fixedly connected between the two ends of the U-shaped rod 331. This design allows the hanging part 33 to suspend the patient's lower limbs in a stable and ergonomic manner. The U-shaped rod 331 opens downward, providing a structure that is convenient for placing the patient's lower limbs, and the arc-shaped plate 332 opens upward, and cooperates with the U-shaped rod 331 to form an arc-shaped space that supports the patient's legs. The operator only needs to place the patient's lower limbs between the U-shaped rod 331 and the arc-shaped plate 332 to start traction treatment. The arc-shaped design of the arc-shaped plate 332 allows the patient's legs to be placed naturally without additional adjustment. The other end of the traction rope 32 is connected to the mounting frame 1 through the elastic stretching part 34. By adjusting the elastic stretching part 34, the magnitude of the traction force can be easily controlled;

[0041] In addition, a sponge pad 333 is provided on the curved side of the curved plate 332. This design takes into account the comfort of the patient during traction. The sponge pad 333 can reduce the pressure points on the patient's legs and improve the patient's comfort.

[0042] In the present application, the clamping and fixing component 2 is a key component to ensure the stability of the traction frame. For details, please refer to Figure 4 The clamping and fixing assembly 2 includes a device plate 21 fixed to the bottom of the mounting frame 1, and U-shaped plates 22 are installed at both ends of the device plate 21. A pressure plate 23 is movably arranged in the opening of the U-shaped plate 22. An adjusting rod 24 is inserted through a thread on the U-shaped plate 22, and one end of the adjusting rod 24 is rotatably connected to the pressure plate 23. A knob 25 is fixed to the other end of the adjusting rod 24. During operation, the operator first moves the mounting frame 1 to a suitable position beside the bed, and then uses the structure of the U-shaped plate 22 and the pressure plate 23 to set the opening of the U-shaped plate 22 on the edge of the bed, and then rotates the knob 25 on the adjusting rod 24. Through the transmission action of the thread, the clamping force between the pressure plate 23 and the edge of the bed is adjusted to ensure the stable fixation of the mounting frame 1;

[0043] In this assembly, the coordinated use of the U-shaped plate 22 and the pressure plate 23 provides a strong clamping force, ensuring the stability of the traction frame during use. The setting of the U-shaped plate 22 enables the clamping and fixing assembly 2 to adapt to the edges of beds of different sizes and shapes.

[0044] To improve the practicality of the device, please refer to Figure 2 and Figure 4The mounting frame 1 is L-shaped and the slide groove 11 is constructed on the vertical side of the mounting frame 1. This design makes full use of the space and provides a stable support. There are two pulleys 31, which are respectively installed on the horizontal side and the vertical side of the mounting frame 1. The slide groove 11 is constructed on the vertical side of the mounting frame 1, providing a vertical channel for the elastic stretching portion 34 to move up and down. A horizontal T-shaped sliding groove 13 is constructed on the mounting frame 1, and a moving block 14 is slidably installed inside the T-shaped sliding groove 13. One of the pulleys 31 is rotatably installed on the moving block 14. A screw rod 15 arranged along the length direction of the T-shaped sliding groove 13 is rotatably installed on the mounting frame 1. One end of the screw rod 15 is rotatably connected to the moving block 14, and a turning handle 16 is fixed to the other end of the screw rod 15.

[0045] In this solution, the screw rod 15 is rotated by rotating the handle 16, thereby driving the moving block 14 to slide along the T-shaped sliding groove 13, adjusting the horizontal position of the hanging part 33, and improving the practicality of the device.

[0046] See also Figure 3 In order to further improve the practicality of the device, a U-shaped block 345 is fixed on the top of the upper adjustment plate 341, and a rotating column 346 is rotatably installed between the two opposite inner walls of the U-shaped block 345. The traction rope 32 is wound around the outer side of the rotating column 346. This structure provides a rotatable fixing point for the traction rope 32. A fixing rod 347 is threadedly inserted on the U-shaped block 345. A fixing block 348 is fixed to the end of the fixing rod 347 corresponding to the traction rope 32, and a rotating block 349 is fixed to the other end of the fixing rod 347. By pulling one end of the traction rope 32, the height of the hanging part 33 can be adjusted. When the height of the hanging part 33 is adjusted, the rotating block 349 is then rotated, and the fixing rod 347 rotates to drive the fixing block 348 to move. The fixing block 348 presses the traction rope 32 tightly on the adjustment plate 341, and the traction rope 32 can be fixed, thereby ensuring the stability of traction treatment and improving the practicality of the device.

[0047] In this embodiment, the cross section of the rotating block 349 is a regular hexagon, which is convenient for adjustment using tools such as a wrench.

[0048] In this plan, the specific steps of traction treatment for the patient's lower limbs are as follows:

[0049] 1. Move the mounting frame 1 of the orthopedic traction frame to the side of the bed, and use the clamping and fixing assembly 2 to fix it to the side of the bed. Adjust the clamping force of the pressure plate 23 by rotating the knob 25 on the adjustment rod 24 to ensure that the mounting frame 1 is stable.

[0050] 2. Ensure that the pulley 31 of the traction assembly 3 has been correctly installed on the vertical and horizontal sides of the mounting frame 1, and adjust the position of the pulley 31 to meet the specific treatment needs of the patient through the T-shaped sliding groove 13 and the screw rod 15, and adjust the height of the suspension part 33;

[0051] 3. Adjust the tension of the traction rope 32 by rotating the handle 16 on the threaded rod 344 until the appropriate traction force is reached;

[0052] Fourth, place the patient's lower limbs between the U-shaped rod 331 and the arc-shaped plate 332 of the suspension part 33, ensure that the patient's lower limbs are comfortably placed on the sponge pad 333, and perform traction treatment.
