Description

Technical Field

[0001] The present invention relates to the field of rehabilitation nursing, and particularly to an auxiliary traction device for orthopedics. Background Art

[0002] In orthopedic clinical treatment, cervical traction is an important treatment method for common diseases such as cervical spondylosis and cervical disc herniation. Its principle is to apply appropriate traction force to the cervical vertebrae, increase the cervical intervertebral space, relieve the compression of the intervertebral disc on the nerve root, relieve muscle spasm, improve the physiological curvature of the cervical vertebrae, so as to achieve the purpose of treating diseases and relieving symptoms.

[0003] When performing cervical traction, the patient usually needs to maintain a sitting position. Existing devices for cervical traction often only support the patient's back and waist through the seat back. During the treatment process, the patient needs to adjust their body posture by themselves to maintain balance and comfort. Since the patient needs to adjust by themselves, the patient's waist cannot be stably supported, and situations such as body shaking, leaning forward or backward are likely to occur, resulting in uneven force on the cervical vertebrae, affecting the accurate transmission of the traction force, and further reducing the effect of traction treatment. At the same time, continuous self-adjustment will keep the patient's waist muscles in a tense state, easily causing waist fatigue, which further affects the treatment effect. To solve the above problems, the present invention provides an auxiliary traction device for orthopedics.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present invention. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0016] In summary, compared with the related art, the present invention has the following beneficial technical effects:

[0017] 1. By setting a lumbar pad on one side of the fixing frame, it can provide effective support for the patient's waist. When the cervical vertebra is tractioned, the patient maintains a sitting position, and the lumbar pad can effectively fix and stably support the patient's waist to avoid body shaking, ensuring that the cervical vertebra is evenly stressed during the traction process, so that the traction force can be accurately transmitted to the cervical vertebra, effectively improving the accuracy and effect of traction treatment. At the same time, two groups of massage balls are symmetrically arranged on one side of the lumbar pad. When the driving component drives the two splints to approach or move away from each other at the same time, the two groups of massage balls rotate synchronously. While the cervical vertebra is being pulled, the patient's waist can be massaged. The rotation of the massage balls can promote blood circulation in the waist and relieve the tension of the waist muscles. The relaxation of the waist muscles helps the patient to better maintain body balance and further improve the effect of traction treatment.

[0018] 2. By arranging two shoulder frames on one side of the bracket, a linkage mechanism is formed with the driving component on the fixed frame. When the driving component drives the two splints to move closer or farther away from each other at the same time, the two shoulder frames also move closer or farther away synchronously, so that the patient's shoulders and waist can be reasonably supported and fixed at the same time. The stability of the shoulder position ensures that the relative position of the cervical spine remains unchanged, thereby avoiding the deviation of the traction force direction and the point of action caused by shoulder displacement, and further improving the effect of traction therapy.

Detailed implementation manners

[0026] The following further elaborates on the present invention in conjunction with the attached Figures 1-6 drawings.

[0027] An embodiment of the present invention discloses an auxiliary traction device for orthopedics. Referring to Figures 1-6 , an auxiliary traction device for orthopedics includes a base 1. A column 2 is fixed on the top of the base 1, a seat cushion 3 is fixed on the top of the column 2, a bracket 4 is fixed on one side of the base 1. A support plate 8 and a lifting assembly for driving the lifting of the support plate 8 are provided on the bracket 4. The lifting assembly includes a first lead screw 6 and a first motor 7. Guide grooves 5 are formed on both sides of the bracket 4. The first lead screw 6 rotates in the guide groove 5, the support plate 8 slides in the guide groove 5, the first lead screw 6 is in threaded connection with the support plate 8, the first motor 7 is fixed on the top of the bracket 4, and the rotor end of the first motor 7 is fixed to the first lead screw 6. Starting the first motor 7 causes the first lead screw 6 to rotate, and the lifting of the support plate 8 is realized under the guiding action of the guide groove 5.

[0028] Referring to Figures 1-3 , a traction belt 20 and a rotating assembly for driving the rotation of the traction belt 20 are provided on the support plate 8. The rotating assembly includes a sliding frame 12, a rotating shaft 13, an external gear ring 14, a first rack 15, a connecting block 16, and an electric push rod 17. The sliding frame 12 slides on the top of the support plate 8, the rotating shaft 13 rotates on the sliding frame 12, a cross bar 18 is fixed to the bottom of the rotating shaft 13, two first connecting rods 19 slide on the cross bar 18, and the other ends of the two first connecting rods 19 are respectively fixed to both ends of the traction belt 20. The external gear ring 14 is fixed to the top of the rotating shaft 13, the first rack 15 slides on the top of the sliding frame 12, the electric push rod 17 is fixed on the top of the sliding frame 12, the telescopic end of the electric push rod 17 is fixed to the connecting block 16, one side of the connecting block 16 is fixed to one side of the first rack 15, the first rack 15 is meshed with the external gear ring 14. Starting the electric push rod 17 pushes the connecting block 16 and the first rack 15 to slide, causing the external gear ring 14 and the rotating shaft 13 thereon to rotate, and further causing the cross bar 18 and the first connecting rods 19 and the traction belt 20 thereon to rotate reciprocally;

[0029] A chute 9 for the sliding frame 12 to slide is formed at the top of the support plate 8. A second lead screw 10 is rotatably arranged in the chute 9. The second lead screw 10 is in threaded connection with the sliding frame 12. A second motor 11 is fixed to one side of the support plate 8. The rotor end of the second motor 11 is fixed to the second lead screw 10. Starting the second motor 11 causes the second lead screw 10 to rotate, and under the guiding action of the chute 9, the sliding frame 12 and the traction belt 20 thereon slide in the chute 9;

[0030] During traction, the patient's head is fixed to the traction belt 20 through a strap or the like. Male patients need to pay attention to avoiding the Adam's apple. Through the reciprocating rotation and sliding of the traction belt 20, it can be automatically adjusted according to the actual position and angle of the patient's neck, so that the traction force acts more evenly on each part of the cervical vertebra, which is beneficial to improving the pertinence and effectiveness of traction treatment.

[0031] Refer to Figure 4 , two shoulder frames 23 are arranged on one side of the bracket 4. A fixing frame 24 is fixed to one side of the bracket 4. Two clamping plates 28 and a driving assembly for driving the two clamping plates 28 to move closer to or away from each other simultaneously are arranged on the fixing frame 24. The driving assembly includes a third motor 29 and a bidirectional lead screw 30. A sliding groove for the two clamping plates 28 to slide is formed in the fixing frame 24. The bidirectional lead screw 30 rotates in the sliding groove. The third motor 29 is fixed to one side of the fixing frame 24. The rotor end of the third motor 29 is fixed to the bidirectional lead screw 30. The bidirectional lead screw 30 is in threaded connection with the two clamping plates 28. Starting the third motor 29 causes the bidirectional lead screw 30 to rotate, and under the guiding action of the sliding groove, the two clamping plates 28 move closer to or away from each other, which can be flexibly adjusted according to the specific body type of the patient, facilitating the support and limitation of the patient's side waist and avoiding the influence of the patient's body shaking on the traction effect during traction;

[0032] It should be noted that one section of the thread on the bidirectional lead screw 30 is a left-handed thread and the other section is a right-handed thread. The two clamping plates 28 are respectively in threaded connection with the left-handed thread and the right-handed thread.

[0033] Refer to Figure 5 , 6, a lumbar cushion 26 is fixed to one side of the fixing frame 24. The lumbar cushion 26 is flexible. Two groups of massage balls 38 are symmetrically arranged on one side of the lumbar cushion 26. A connecting plate 25 is fixed to one side of the fixing frame 24. One side of the connecting plate 25 is fixed to the lumbar cushion 26. A rotating shaft 39 is rotatably arranged between the connecting plate 25 and the lumbar cushion 26. A plurality of massage balls 38 are equidistantly arranged on the rotating shaft 39. A second bevel gear 37 is fixed to the top of the rotating shaft 39. A connecting groove 31 communicating with the connecting plate 25 is formed in the inner wall of the sliding groove. A supporting block 32 is fixed in the connecting groove 31. A connecting shaft 33 is rotatably arranged on the supporting block 32. A first bevel gear 34 and a gear 35 are respectively fixed to both ends of the connecting shaft 33. The first bevel gear 34 meshes with the second bevel gear 37. A second rack 36 is slidably arranged on the inner wall of the sliding groove. One side of the second rack 36 is fixed to one side of the clamping plate 28. The second rack 36 meshes with the gear 35. A horizontal groove 22 for two shoulder frames 23 to slide is formed in one side of the bracket 4. A second connecting rod 27 is fixed between the shoulder frame 23 and the clamping plate 28. When the two clamping plates 28 approach or move away from each other simultaneously, under the guiding action of the horizontal groove 22 and the connecting action of the second connecting rod 27, the two shoulder frames 23 also approach or move away synchronously to limit the shoulders of the patient and keep the shoulders relatively stable. At the same time, the second rack 36 slides as the clamping plate 28 slides, thereby driving the gear 35 to rotate. Under the connecting action of the connecting shaft 33, the first bevel gear 35 drives the second bevel gear 37 to rotate, thereby driving the rotating shaft 39 and the massage balls 38 thereon to rotate synchronously to massage the waist of the patient, promote blood circulation in the waist, and relieve the tension of the waist muscles. The relaxation of the waist muscles helps the patient better maintain body balance and further improve the traction treatment effect. At the same time, the lumbar cushion 26 and the two clamping plates 28 cooperate with each other to jointly support the waist of the patient. The support and limitation of the clamping plate 28 on the side waist can share a part of the body weight, reduce the pressure on the lumbar cushion, and make the waist support more uniform and stable;

[0034] It should be noted that two connecting grooves 31 communicating with the connecting plate 25 are formed in the inner wall of the sliding groove. The two connecting grooves 31 are symmetrically arranged about the center. Therefore, one connecting groove 31 is located above, and one connecting groove 31 is located below the symmetric side. As a result, one second bevel gear 37 is located at the top of a rotating shaft 39, and the other second bevel gear 37 is located at the bottom of a rotating shaft 39. Therefore, the two second racks 36 will not interfere with each other when sliding along with the clamping plate 28, thereby realizing the synchronous rotation of the two groups of massage balls 38.

[0035] Refer to Figure 1 , two groups of limit sleeves 21 are slidably arranged on the cross bar 18. One ends of the two connecting rods 19 are respectively located between a group of limit sleeves 21 to limit the connecting rod 19 and the traction belt 20 thereon, so as to ensure that the traction belt 20 can accurately act on the neck of the patient and provide a suitable traction angle and strength. The limit sleeve 21 can be a nut, and the nut needs to be threadedly connected to the cross bar 18. At this time, the cross bar 18 needs to be a threaded rod.
