The inner wall of the fixing belt is fixedly connected to a connecting component, which is used to assist in fixing the traction rope on the patient's leg. The connecting component is connected to the fixing belt; and a traction component, which 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 connecting piece fixedly connected to the inner wall of the fixing belt, a large arc groove is provided at the center of the connecting piece, small arc grooves are symmetrically provided on both sides of the connecting piece, a flange portion is provided on the side of the small arc groove away from the large arc groove, and evenly distributed weakening grooves are provided through the connection between the large arc groove and the small arc groove and the center of the flange portion.

[0008] Optionally, connection grooves are symmetrically provided on the inner wall of the fixing belt at positions corresponding to the connecting pieces, and ventilation holes are provided on the inner wall of the fixing belt at positions corresponding to the connection grooves and at the center between the adjacent connecting pieces.

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

[0010] Optionally, both ends of the fixing belt are fixedly connected with matching Velcro strips, and the width of the fixing belt is smaller than the width of the connecting piece.

[0011] Optionally, the pulling assembly includes a pulling frame that is clamped with the traction rope, and the pulling frame is fixedly connected to an upper placement groove and a lower placement groove on the side close to the fixing belt, and the upper placement groove and the lower placement groove are respectively located at the top and bottom of the pulling frame, and the center of the pulling frame is fixedly connected to an outer placement groove on the side away from the fixing belt, and the top of the pulling frame is fixedly connected to a hook.

[0012] Optionally, the upper placement groove, the lower placement groove and the outer placement groove are all penetrated by evenly distributed lightweight grooves, and the upper placement groove, the lower placement groove, the outer placement groove and the pulling frame are an integrated manufacturing structure.

[0013] Optionally, a mounting hole is provided through the pulling frame, and the mounting hole is located below the outer placement groove. A bolt is threadedly installed through the mounting hole on the side of the pulling frame close to the fixing belt, and a nut is threadedly connected to the outer wall of the bolt. The outer wall size of the bolt is adapted to the inner wall size of the mounting hole.

[0014] Optionally, one end of the bolt close to the fixing belt is fixedly connected to a footrest, a spring is sleeved on the bolt, and the spring is located between the footrest and the pulling frame.

[0015] Optionally, the height dimensions of the upper placement groove, the lower placement groove and the outer placement groove are greater than the diameter dimension of the large massage beads, 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 beads and the small massage beads.

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

[0017] In the above scheme, a connecting component and a traction component are provided, and the connecting component and the traction component are respectively provided on the patient's legs and feet. The connecting component can not only adjust the relative position relationship between the fixing belt and the traction rope to adapt to patients of different heights, but also relax the patient's leg muscles through the cooperation of the large massage beads and the small massage beads on the traction rope, thereby 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, which is convenient for adjusting the traction distance for different heights.

[0019] By setting a weakened groove and a flange part, the connecting piece is an integrated curved elastic structure. The integrated manufacturing structure allows for more flexible design and can better adapt to complex shapes and functional requirements. At the same time, it optimizes the internal space utilization rate. By utilizing the cooperation of the weakened groove and the flange part, the traction rope can easily enter the interior of the connecting piece and slide easily, which saves manpower while making the massage process smoother and improving comfort.

[0020] By setting up a traction frame and a footrest, upper placement grooves, lower placement grooves and outer placement grooves of different heights are set inside and outside the traction frame, which facilitates the fixation and limitation of the traction rope, so that the traction rope together with the large massage beads and the small massage beads can only move within the placement grooves 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 can adjust the distance between the patient and the traction frame to adapt to the traction effect of different people.

[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. The inner wall of the fixation belt 1 is fixedly connected with a connecting component, which is used to assist the traction rope 5 in being fixed on the patient's leg, and the connecting component is connected to the fixation belt 1; a traction component, which is used to traction and stretch 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 by this application is suitable for traction and stretching the patient's legs 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 relieve pain through continuous tension.

[0040] By setting up a connecting component and a traction component, the connecting component and the traction component are respectively set on the patient's legs and feet. The connecting component can not only adjust the relative position relationship between the fixing belt 1 and the traction rope 5 to adapt to patients of different heights, but also through the cooperation of the large massage beads 6 and the small massage beads 7 on the traction rope 5, the patient's leg muscles are relaxed to enhance 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, which is convenient for adjusting the traction distance of different heights. The combination of traction stretching and leg massage can effectively improve the limb function of patients after surgery, improve blood circulation, relieve pain and enhance joint function, and accelerate the recovery process.

[0041] like Figures 1 to 6 As shown, the connecting assembly includes a connecting member 8 fixedly connected to the inner wall of the fixing belt 1, a large arc groove 9 is opened at the center of the connecting member 8, small arc grooves 10 are symmetrically opened on both sides of the connecting member 8, and a flange portion 12 is provided on the side of the small arc groove 10 away from the large arc groove 9. The connection between the large arc groove 9 and the small arc groove 10 and the center of the flange portion 12 are penetrated by uniformly distributed weakening grooves 11 (such as Figure 6 As shown, the inner wall of the fixing belt 1 is symmetrically provided with connecting grooves 4 at positions corresponding to the connecting members 8 (as shown in FIG. Figure 5 As shown, ventilation holes 3 are provided on the inner wall of the fixing belt 1 at the positions of the connection grooves 4 and the center between the corresponding adjacent connecting pieces 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 the small massage beads 7 are alternately connected in series (as shown in FIG. Figure 3 As shown), the outer wall size of the large massage beads 6 is adapted to the inner wall size of the air vent 3, the outer wall size of the small massage beads 7 is adapted to the inner wall size of the connecting groove 4, and the two ends of the fixing belt 1 are fixedly connected with matching Velcro 2, and the width of the fixing belt 1 is smaller than the width of the connecting piece 8.

[0042] Specifically, four fixing belts 1 are set on the patient's legs, two above and below the knees. By changing the relative relationship between the connecting piece 8 and the traction rope 5, the connecting piece 8 can be clamped to the large massage beads 6 and the small massage beads 7 at any position on the traction rope 5, thereby adjusting the spacing between adjacent fixing belts 1 to adapt to patients with different heights and leg lengths. The large massage beads 6 and the small massage beads 7 are made of hard wood material, which can better transmit the pressure during massage. The fixing belt 1 is made of nylon, which has high strength and good wear resistance. The connecting pieces 8 fixedly connected on the inner wall of the fixing belt 1 are symmetrically and evenly distributed. By clamping the traction rope 5 on the connecting pieces 8 at different positions, the required When massaging, external force is applied by hand to pull the traction rope 5 so that it can accurately correspond to specific acupuncture points on the body and the positions that need to be massaged. By continuously pulling the traction rope 5, the large massage beads 6 and the small massage beads 7 move synchronously with the traction rope 5 under the action of external force. The legs can be massaged by sliding the large massage beads 6 and the small massage beads 7. Pressure can also be applied to the body by pressing the large massage beads 6 and the small massage beads 7, thereby achieving a massage effect. Muscles in different parts of the body can be massaged and relaxed. The tightness of the fixing belt 1 can be adjusted and fixed using the Velcro 2. The specific structure and working principle of the Velcro 2 are disclosed as prior art and will not be elaborated on here.

[0043] By providing large massage beads 6, small massage beads 7 and connectors 8, the layering and diversity of massage can be increased. The large massage beads 6 provide deep massage, promote blood circulation and muscle relaxation; the small massage beads 7 can perform surface massage, relieve fatigue and soreness, and improve the comfort of massage. In addition, the traction rope 5, large massage beads 6 and small massage beads 7 are an integrated manufacturing structure, which not only reduces the number of parts and connection points, significantly improves the strength and rigidity of the overall structure, but also has a simple and ingenious structure, and is convenient and labor-saving in actual operation.

[0044] Furthermore, a flange portion 12 is provided at the end of the small arc groove 10, and a wide-mouth design is provided at both ends of the connector 8, so as to facilitate pulling the large massage beads 6 and the small massage beads 7 into the connector 8. Furthermore, 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 portion 12. The connector 8 as a whole is a curved elastic structure, and the weakening groove 11 thins the connection position between the two. This arrangement makes it easier for the connector 8 to bend and deform at the position of the weakening groove 11 under the action of external force, thereby ensuring that the traction rope 5 can slide conveniently under the action of external force, thereby effectively massaging the patient's legs, making it more labor-saving when the hand pulls the traction rope 5, and also limiting the traction rope 5 to slide only along the direction of the connector. Figure 3As shown, when the traction rope 5 is pulled by hand, the large massage beads 6 and the small massage beads 7 will pass through the connecting piece 8 in turn. 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 connecting piece 8. Since the connecting piece 8 is elastic and uniformly 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 portion 12, the connection between the large arc groove 9 and the small arc groove 10 and the flange portion 12 are more easily stretched by the large massage beads 6, thereby facilitating the sliding of the large massage beads 6. By providing the weakening grooves 11 and the flange portion 12, the connecting piece 8 is an integrally manufactured curved elastic structure. The integral manufacturing structure allows for more flexible design, can better adapt to complex shapes and functional requirements, and optimizes the internal space utilization rate. By utilizing the cooperation of the weakening grooves 11 and the flange portion 12, the traction rope 5 can easily enter the interior of the connecting piece 8 and slide conveniently, saving manpower while also 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 is clamped with the traction rope 5. The pulling frame 17 is fixedly connected to an upper placement groove 20 and a lower placement groove 21 on the side close to the fixing belt 1. The upper placement groove 20 and the lower placement groove 21 are respectively located at the top and bottom of the pulling frame 17. The center of the pulling frame 17 is fixedly connected to an outer placement groove 18 on the side away from the fixing belt 1. The top of the pulling frame 17 is fixedly connected with a hook 22. The upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are all penetrated with evenly distributed lightweight grooves 19. The upper placement groove 20, the lower placement groove 21, the outer placement groove 18 and the pulling frame 17 are an integrated manufacturing structure. The pulling frame is penetrated with a mounting hole 16 for installation. The mounting hole 16 is located below the outer placement groove 18. A bolt 14 is threadedly installed on the side of the pulling frame 17 close to the fixing belt 1 through the mounting hole 16. A nut 15 is threadedly connected to 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. The bolt 14 is fixedly connected to the end of the fixing belt 1 with a footrest 13. A spring is sleeved on the bolt 14, and the spring is located between the footrest 13 and the pulling frame 17. The height dimensions of the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are greater than the diameter dimension of the large massage beads 6. The inner wall dimensions of the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are all adapted to the outer wall dimensions of the large massage beads 6 and the small massage beads 7.

[0046] Specifically, an upper placement groove 20, a lower placement groove 21 and an outer placement groove 18 of different heights are set inside and outside the traction frame 17. The inner walls 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 beads 6 and the small massage beads 7, which is convenient for fixing and limiting the traction rope 5. The upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 correspond to the connector 8 at different positions respectively, so as to pull the traction rope 5 at different heights to ensure that the massage does not affect the traction effect. The hook 22 fixedly connected to the top of the traction frame 17 is connected by The hook 22 hangs the pulling frame 17 on the bed foot frame to fix the pulling frame 17. The upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are all penetrated by a lightweight groove 19. The use of the lightweight groove 19 not only saves materials to a certain extent, but also performs thinning processing through the lightweight groove 19. Such an arrangement makes it easier for the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 to bend and deform from the position of the lightweight groove 19 under the action of external force, so that the traction rope 5 connects the large massage beads 6 and the small massage beads 7 to pass through the pulling frame 17 conveniently.

[0047] During use, the patient's feet are placed on the footrest 13, and the position of the fixing belt 1 is adjusted according to the height. After fixing the fixing belt 1, the appropriate distance is adjusted by the bolts 14 and nuts 15 to ensure effective traction of the patient's legs. The specific structure and working principle of the bolts 14 and nuts 15 are disclosed as existing technologies, so they will not be described in detail. By setting up a traction frame 17 and a footrest 13, upper placement grooves 20, lower placement grooves 21 and outer placement grooves 18 of different heights are set inside and outside the traction frame 17, which facilitates the fixing and limiting of the traction rope 5, so that the traction rope 5 together with the large massage beads 6 and the small massage beads 7 can only move in the placement grooves on the traction frame 17, effectively improving the stability of the overall structure. The footrest 13 not only provides support for the patient's feet but also can adjust the distance relationship 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 the present invention is as follows:

[0049] The patient lies flat on the bed, places his feet on the footrest 13 first, and then adjusts the position of the fixing belt 1 according to his height. Since four fixing belts 1 are set on the patient's legs, two above and below the knees, by changing the relative relationship between the connecting piece 8 and the traction rope 5, the connecting piece 8 can be used to clamp the large massage beads 6 and the small massage beads 7 at any position on the traction rope 5, thereby adjusting the distance between adjacent fixing belts 1 to adapt to patients with different heights and leg lengths. The connecting pieces 8 fixedly connected on the inner wall of the fixing belt 1 are symmetrically and evenly distributed. By clamping the traction rope 5 on the connecting pieces 8 at different positions, when massage is needed, the traction rope 5 is pulled by applying external force by hand so that it can accurately correspond to specific acupuncture points on the body and the position that needs massage.

[0050] By continuously pulling the traction rope 5, the large massage beads 6 and the small massage beads 7 move synchronously with the traction rope 5 under the action of external force, and the legs are massaged by the sliding of the large massage beads 6 and the small massage beads 7. The large massage beads 6 and the small massage beads 7 can also be pressed to apply pressure to the body, thereby achieving a massage effect, and can massage and relax muscles in different parts of the body. When the traction rope 5 is pulled by hand, the large massage beads 6 and the small massage beads 7 will pass through the connecting member 8 in turn. 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 connecting member 8. Since the connecting member 8 is elastic and uniformly distributed weakening grooves 11 are provided at the connection between the large arc groove 9 and the small arc groove 10 and the flange 12, the connection between the large arc groove 9 and the small arc groove 10 and the flange 12 are more easily opened by the large massage beads 6, thereby facilitating the sliding of the large massage beads 6, and then effectively massaging the patient's legs.

[0051] After adjusting the fixing belt 1, the hook 22 fixedly connected to the top of the pulling frame 17 is used to hang the pulling frame 17 on the bed end frame, and the pulling frame 17 is fixed. Then, the traction rope 5 is placed on the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 at the corresponding positions, and the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are all penetrated with a lightweight groove 19, so that the upper placement groove 20, the lower placement groove 21 and the outer placement groove 18 are more easily moved from the position of the lightweight groove 19 under the action of external force. The traction rope 5 is bent and deformed so that the traction rope 5 can connect the large massage beads 6 and the small massage beads 7 and pass through the traction frame 17 conveniently. After fixing the fixing belt 1 and the massage beads, the appropriate spacing is adjusted by the bolts 14 and the nuts 15 to ensure effective traction of the patient's legs. After determining the traction spacing, while ensuring the traction effect, the traction rope 5 is manually pulled in opposite directions on both sides of the legs. The traction rope 5 drives the large massage beads 6 and the small massage beads 7 to massage the patient's legs, thereby relaxing the patient's leg muscles and enhancing the effect of rehabilitation training.

[0052] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
