Description

Technical Field

[0001] This invention relates to the field of orthopedic rehabilitation assistive equipment technology, and in particular to a traction and stretching device for postoperative recovery of orthopedic trauma. Background Technology

[0002] For patients with traumatic femoral head necrosis due to hip dislocation after orthopedic trauma repair surgery, traction and stretching devices are needed for auxiliary treatment. Traction and stretching devices can effectively improve postoperative blood circulation, relieve muscle spasms, prevent joint stiffness, and improve joint function through stretching training.

[0003] Patients who have undergone hip surgery usually need to rest in bed for a long time to avoid secondary damage to the repair site caused by weight-bearing and excessive activity. Although current traction and stretching devices can meet some rehabilitation needs, they still have some shortcomings: they are limited in function and cannot massage the legs to relieve postoperative muscle tension and fatigue; they have poor adaptability and cannot be adapted to patients of different heights, which reduces the applicability of traction and stretching devices. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a traction and stretching device for postoperative recovery of orthopedic trauma, so as to solve the problems of limited functionality and poor adaptability of existing traction and stretching devices.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A traction and stretching device for postoperative recovery of orthopedic trauma includes a fixation strap and a traction rope. The inner wall of the fixation strap is fixedly connected to a connecting component, which is used to assist the traction rope in fixing to the patient's leg. The connecting component is connected to the fixation strap. A traction component is used to traction and stretch the patient's leg. The traction component is connected to the traction rope.

[0007] Optionally, the connecting assembly includes a connector fixedly connected to the inner wall of the fixing band. A large arc-shaped groove is provided at the center of the connector, and small arc-shaped grooves are symmetrically provided on both sides of the connector. A flange is provided on the side of the small arc-shaped groove away from the large arc-shaped groove. A uniformly distributed weakening groove is provided through the connection between the large arc-shaped groove and the small arc-shaped groove and at the center of the flange.

[0008] Optionally, the inner wall of the fixing band is symmetrically provided with connecting grooves at the positions corresponding to the connecting members, and ventilation holes are provided at the center of the inner wall of the fixing band corresponding to the positions of the connecting grooves and the centers of the adjacent connecting members.

[0009] Optionally, a large massage bead and a small massage bead are fixedly connected to the outer wall of the traction rope. The large massage bead and the small massage bead are connected in series alternately. The outer wall size of the large massage bead is adapted to the inner wall size of the vent hole, and the outer wall size of the small massage bead is adapted to the inner wall size of the connecting groove.

[0010] Optionally, the two ends of the fixing strap are fixedly connected with mutually cooperating Velcro, and the width of the fixing strap is smaller than the width of the connector.

[0011] Optionally, the pulling assembly includes a pulling frame that engages with the traction rope. An upper placement slot and a lower placement slot are fixedly connected to the side of the pulling frame near the fixing strap. The upper placement slot and the lower placement slot are located at the top and bottom of the pulling frame, respectively. An outer placement slot is fixedly connected to the center of the pulling frame away from the fixing strap. A hook is fixedly connected to the top of the pulling frame.

[0012] Optionally, the upper placement slot, the lower placement slot, and the outer placement slot are all provided with uniformly distributed lightweight slots, and the upper placement slot, the lower placement slot, the outer placement slot, and the traction frame are integrally manufactured structures.

[0013] Optionally, the traction frame has a through-hole located below the outer placement groove. A bolt is threadedly installed on the side of the traction frame near the fixing belt through the mounting hole. A nut is threaded onto the outer wall of the bolt, and the outer wall size of the bolt is adapted to the inner wall size of the mounting hole.

[0014] Optionally, a foot support is fixedly connected to one end of the bolt near the fixing strap, and a spring is sleeved on the bolt, with the spring located between the foot support and the traction frame.

[0015] Optionally, the height of the upper placement groove, the lower placement groove, and the outer placement groove is greater than the diameter of the large massage bead, and the inner wall dimensions of the upper placement groove, the lower placement groove, and the outer placement groove are all adapted to the outer wall dimensions of the large massage bead and the small massage bead.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above-mentioned scheme, a connecting component and a traction component are set up, which are respectively placed on the patient's legs and feet. The connecting component can not only adjust the relative position between the fixation strap and the traction rope to accommodate patients of different heights, but also relax the patient's leg muscles through the large and small massage beads on the traction rope, enhancing the effect of rehabilitation training. The traction component can not only pull and fix the patient's legs, but also support the patient's feet, making it easy to adjust the traction distance for different heights. The combination of traction and leg massage can effectively improve the postoperative limb function of patients, improve blood circulation, relieve pain, enhance joint function, and accelerate the recovery process.

[0018] By incorporating large and small massage beads and connecting parts, the massage experience can be enhanced in terms of depth and variety. The large massage beads provide deep massage, promoting blood circulation and muscle relaxation, while the small massage beads offer surface massage to relieve fatigue and soreness, thus improving the comfort of the massage. Furthermore, the traction rope, large and small massage beads are manufactured as a single unit, which not only reduces the number of parts and connection points, significantly improving the overall strength and rigidity of the structure, but also features a simple and ingenious design that makes it convenient and effortless to operate.

[0019] By incorporating weakening grooves and flanges, the connector is a one-piece manufactured curved elastic structure. This one-piece manufacturing structure allows for more flexible design, better adapting to complex shapes and functional requirements, while optimizing the utilization of internal space. The combination of weakening grooves and flanges allows the traction rope to easily enter the connector and slide smoothly, saving manpower and making the massage process smoother and more comfortable.

[0020] By setting up a traction frame and footrest, the traction frame has upper, lower, and outer placement slots of different heights inside and outside, which facilitates the fixing and limiting of the traction rope. This ensures that the traction rope, along with the large and small massage beads, can only move within the placement slots on the traction frame, effectively improving the stability of the overall structure. The footrest not only provides support for the patient's feet but also adjusts the distance between the patient and the traction frame to adapt to the traction effect for different groups of people.

[0034] The present invention provides a traction and stretching device for postoperative recovery of orthopedic trauma, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0035] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0039] like Figures 1 to 9As shown, an embodiment of the present invention provides a traction and stretching device for postoperative recovery of orthopedic trauma, including a fixation belt 1 and a traction rope 5. A connecting component is fixedly connected to the inner wall of the fixation belt 1, which is used to assist in fixing the traction rope 5 to the patient's leg. The connecting component is connected to the fixation belt 1. A traction component is used to perform traction and stretching on the patient's leg, and the traction component is connected to the traction rope 5. The traction and stretching device for postoperative recovery of orthopedic trauma provided in this application is suitable for traction and stretching of the patient's leg after hip dislocation repair surgery. In actual operation, the traction and stretching device can not only improve local blood circulation, reduce postoperative swelling, and promote tissue repair by stretching the lower limbs, but also effectively prevent joint stiffness and maintain joint mobility. Traction and stretching can relieve muscle tension and reduce pain through continuous tension.

[0040] By setting up connecting and traction components, which are respectively installed on the patient's legs and feet, the connecting components can not only adjust the relative position between the fixing strap 1 and the traction rope 5 to accommodate patients of different heights, but also relax the patient's leg muscles through the large massage beads 6 and small massage beads 7 on the traction rope 5, enhancing the effect of rehabilitation training. The traction components can not only pull and fix the patient's legs, but also support the patient's feet, making it easy to adjust the traction distance for different heights. The combination of traction and leg massage can effectively improve the limb function of postoperative patients, improve blood circulation, relieve pain, enhance joint function, and accelerate the recovery process.

[0041] like Figures 1 to 6 As shown, the connecting assembly includes a connector 8 fixedly connected to the inner wall of the fixing belt 1. A large arc-shaped groove 9 is formed at the center of the connector 8, and small arc-shaped grooves 10 are symmetrically formed on both sides of the connector 8. A flange 12 is provided on the side of the small arc-shaped groove 10 away from the large arc-shaped groove 9. Evenly distributed weakening grooves 11 (such as...) are formed through the connection between the large arc-shaped groove 9 and the small arc-shaped groove 10, and at the center of the flange 12. Figure 6 As shown), symmetrical connecting grooves 4 are provided on the inner wall of the fixing band 1 at the positions corresponding to the connecting parts 8 (as shown). Figure 5 As shown), ventilation holes 3 are provided at the center of the inner wall of the fixing belt 1 corresponding to the connecting groove 4 and the center of the adjacent connecting piece 8. Large massage beads 6 and small massage beads 7 are fixedly connected to the outer wall of the traction rope 5. The large massage beads 6 and small massage beads 7 are connected in series alternately (as shown). Figure 3 As shown), the outer wall size of the large massage bead 6 is adapted to the inner wall size of the vent 3, the outer wall size of the small massage bead 7 is adapted to the inner wall size of the connecting groove 4, and the two ends of the fixing strap 1 are fixedly connected with mutually cooperating Velcro 2. The width of the fixing strap 1 is smaller than the width of the connector 8.

[0042] Specifically, four fixing straps 1 are installed on the patient's legs, two above and two below the knee. By changing the relative relationship between the connecting piece 8 and the traction rope 5, the connecting piece 8 can be engaged with large massage beads 6 and small massage beads 7 at any position on the traction rope 5, thereby adjusting the spacing between adjacent fixing straps 1 to accommodate patients of different heights and leg lengths. The large massage beads 6 and small massage beads 7 are made of hard wood, which can better transmit the pressure during massage. The fixing straps 1 are made of nylon, which has high strength and good wear resistance. The connecting pieces 8 are symmetrically and evenly distributed on the inner wall of the fixing straps 1. By engaging the traction rope 5 with the connecting pieces 8 at different positions, the spacing between adjacent fixing straps 1 can be adjusted to accommodate patients of different heights and leg lengths. When a massage is needed, the traction rope 5 is pulled by applying external force with the hand, so that it can accurately correspond to specific acupoints and areas that need massage. By continuously pulling the traction rope 5, the large massage beads 6 and small massage beads 7 move synchronously with the traction rope 5 under the action of external force. The legs are massaged by the sliding of the large massage beads 6 and small massage beads 7. Pressure can also be applied to the body by pressing the large massage beads 6 and small massage beads 7, thereby achieving a massage effect. It can massage and relax the muscles in different parts of the body. The tightness of the fixing band 1 is adjusted and fixed by using Velcro 2. The specific structure and working principle of Velcro 2 are disclosed as existing technology and will not be described in detail here.

[0043] By incorporating large massage beads 6, small massage beads 7, and connectors 8, the massage experience can be enhanced in terms of depth and variety. Large massage beads 6 provide deep massage, promoting blood circulation and muscle relaxation; small massage beads 7 provide surface massage, relieving fatigue and soreness, thus improving the comfort of the massage. Furthermore, the traction rope 5, large massage beads 6, and small massage beads 7 are manufactured as a single unit, which not only reduces the number of parts and connection points, significantly improving the overall strength and rigidity of the structure, but also features a simple and ingenious design, making it convenient and effortless to operate.

[0044] Furthermore, a flange 12 is provided at the end of the small arc-shaped groove 10, and the two ends of the connector 8 are designed with wide openings to facilitate the pulling of the large massage beads 6 and the small massage beads 7 into the connector 8. Moreover, evenly distributed weakening grooves 11 are provided at the connection between the large arc-shaped groove 9 and the small arc-shaped groove 10, and on the flange 12. The connector 8 is a curved elastic structure, and the weakening grooves 11 thin the connection point. This design makes it easier for the connector 8 to bend and deform under external force from the position of the weakening grooves 11, thus ensuring that the traction rope 5 slides easily under external force, effectively massaging the patient's legs. This makes pulling the traction rope 5 easier and also restricts the traction rope 5 to slide only along the direction of the connector. Figure 3As shown, when the traction rope 5 is pulled, the large massage beads 6 and the small massage beads 7 pass through the connector 8 in sequence. Under the action of the pulling force, the large massage beads 6 squeeze the connection between the large arc groove 9 and the small arc groove 10 on the connector 8. Since the connector 8 is elastic, and the evenly distributed weakening grooves 11 are provided at the connection between the large arc groove 9 and the small arc groove 10 and on the flange 12, the large massage beads 6 can more easily open the connection between the large arc groove 9 and the small arc groove 10 and the flange 12, thus facilitating the sliding of the large massage beads 6. By setting the weakening grooves 11 and the flange 12, the connector 8 is a one-piece manufactured curved elastic structure. The one-piece manufacturing structure allows for more flexible design, can better adapt to complex shapes and functional requirements, and optimizes the utilization of internal space. With the cooperation of the weakening grooves 11 and the flange 12, the traction rope 5 can easily enter the interior of the connector 8 and slide easily, saving manpower and making the massage process smoother and improving comfort.

[0045] like Figures 1 to 3 and Figures 7 to 9 As shown, the pulling assembly includes a pulling frame 17 that engages with the traction rope 5. An upper placement groove 20 and a lower placement groove 21 are fixedly connected to the side of the pulling frame 17 closest to the fixing belt 1. The upper placement groove 20 and the lower placement groove 21 are located at the top and bottom of the pulling frame 17, respectively. An outer placement groove 18 is fixedly connected to the center of the pulling frame 17 away from the fixing belt 1. A hook 22 is fixedly connected to the top of the pulling frame 17. Evenly distributed lightweight grooves 19 are provided through the upper placement groove 20, the lower placement groove 21, and the outer placement groove 18. The upper placement groove 20, the lower placement groove 21, the outer placement groove 18, and the pulling frame 17 are integrally manufactured. Mounting holes 16 are provided through the pulling frame for mounting. The mounting hole 16 is located below the outer placement groove 18. The side of the pull frame 17 near the fixing band 1 is threaded with a bolt 14 through the mounting hole 16. A nut 15 is threaded onto the outer wall of the bolt 14. The outer wall size of the bolt 14 is adapted to the inner wall size of the mounting hole 16. A foot support 13 is fixedly connected to the end of the bolt 14 near the fixing band 1. A spring is sleeved on the bolt 14. The spring is located between the foot support 13 and the pull frame 17. The height of the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 is greater than the diameter of the large massage bead 6. The inner wall size of the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are adapted to the outer wall size of the large massage bead 6 and the small massage bead 7.

[0046] Specifically, upper placement slots 20, lower placement slots 21, and outer placement slots 18 at different heights are provided inside and outside the traction frame 17. The inner walls of the upper placement slots 20, lower placement slots 21, and outer placement slots 18 are adapted to the outer wall dimensions of the large massage beads 6 and the small massage beads 7, facilitating the fixing and limiting of the traction rope 5. The upper placement slots 20, lower placement slots 21, and outer placement slots 18 correspond to connectors 8 at different positions, so as to pull the traction rope 5 at different heights, ensuring that the massage does not affect the traction effect. The hook 22 fixedly connected to the top of the traction frame 17, through... The hook 22 suspends the traction frame 17 on the bed end frame and fixes the traction frame 17. Lightweight grooves 19 are opened through the upper placement groove 20, lower placement groove 21 and outer placement groove 18. The lightweight grooves 19 not only save materials to a certain extent, but also make the material thinner. This design makes it easier for the upper placement groove 20, lower placement groove 21 and outer placement groove 18 to bend and deform at the position of the lightweight grooves 19 under the action of external force, so that the traction rope 5 can easily pass through the traction frame 17 to connect the large massage bead 6 and the small massage bead 7.

[0047] In use, the patient's foot is placed on the footrest 13, and the position of the fixing strap 1 is adjusted according to the patient's height. After fixing the fixing strap 1, the appropriate spacing is adjusted by bolts 14 and nuts 15 to ensure effective traction of the patient's leg. The specific structure and working principle of bolts 14 and nuts 15 are disclosed as prior art and will not be described in detail. By setting up the traction frame 17 and the footrest 13, the traction frame 17 is provided with upper placement slots 20, lower placement slots 21 and outer placement slots 18 of different heights, which facilitates the fixing and limiting of the traction rope 5. This ensures that the traction rope 5, together with the large massage beads 6 and the small massage beads 7, can only move within the placement slots on the traction frame 17, effectively improving the stability of the overall structure. In addition to providing support for the patient's foot, the footrest 13 can also adjust the spacing between the patient and the traction frame 17 to adapt to the traction effect of different people.

[0048] The workflow of the technical solution provided by this invention is as follows:

[0049] The patient lies flat on the hospital bed with their feet first placed on the footrest 13. Then, the position of the fixation strap 1 is adjusted according to the patient's height. Since four fixation straps 1 are set on the patient's legs, two above and two below the knee, the relative relationship between the connector 8 and the traction rope 5 can be changed. The connector 8 can be snapped onto the large massage beads 6 and small massage beads 7 at any position on the traction rope 5, thereby adjusting the spacing between adjacent fixation straps 1 to accommodate patients of different heights and leg lengths. The connectors 8 fixedly connected to the inner wall of the fixation strap 1 are symmetrically and evenly distributed. By snapping the traction rope 5 onto the connectors 8 at different positions, when massage is needed, external force is applied by hand to pull the traction rope 5, so that it can accurately correspond to specific acupoints and areas that need massage.

[0050] By continuously pulling the traction rope 5, the large massage beads 6 and small massage beads 7 move synchronously with the traction rope 5 under the action of external force. The legs are massaged by the sliding of the large massage beads 6 and small massage beads 7. Pressure can also be applied to the body by pressing the large massage beads 6 and small massage beads 7, thereby achieving a massage effect. It can massage and relax the muscles in different parts. When the traction rope 5 is pulled, the large massage beads 6 and small massage beads 7 will pass through the connector 8 in sequence. Under the action of tension, the large massage beads 6 squeeze the connection between the large arc groove 9 and the small arc groove 10 on the connector 8. Since the connector 8 is elastic, and there are evenly distributed weakening grooves 11 at the connection between the large arc groove 9 and the small arc groove 10 and the flange 12, the large massage beads 6 can more easily open the connection between the large arc groove 9 and the small arc groove 10 and the flange 12, thereby facilitating the sliding of the large massage beads 6 and effectively massaging the patient's legs.

[0051] After adjusting the fixing strap 1, use the hook 22 fixedly connected to the top of the traction frame 17 to suspend the traction frame 17 from the bed end frame and fix the traction frame 17. Then place the traction rope 5 on the upper placement slot 20, lower placement slot 21, and outer placement slot 18 at the corresponding positions. Lightweight slots 19 are opened through the upper placement slot 20, lower placement slot 21, and outer placement slot 18, making it easier for the upper placement slot 20, lower placement slot 21, and outer placement slot 18 to open from the position of the lightweight slots 19 under the action of external force. The traction rope 5 bends and deforms to facilitate the connection between the large massage bead 6 and the small massage bead 7 and allow them to pass easily through the traction frame 17. After fixing the fixing strap 1 and the massage beads, the appropriate spacing is adjusted using bolts 14 and nuts 15 to ensure effective traction of the patient's legs. Once the traction spacing is determined, and the traction effect is ensured, the traction rope 5 is manually pulled in opposite directions on both sides of the leg. The traction rope 5 drives the large massage bead 6 and the small massage bead 7 to massage the patient's legs, thereby relaxing the leg muscles and enhancing the effect of rehabilitation training.

To provide the public with a thorough understanding of this invention, specific details are described in detail in the preferred embodiments, while those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0053] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
