Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a postoperative care brace for spinal deformity surgery to prevent secondary injury. Background Technology

[0002] Spinal deformity surgery is a treatment used to correct abnormal curvatures of the spine (such as scoliosis, kyphosis, etc.) or severe structural abnormalities. It is usually suitable for situations where conservative treatment is ineffective or where the disease progresses and threatens cardiopulmonary and neurological functions. After spinal deformity surgery, braces (orthoses) are important auxiliary tools, mainly used to protect the surgical site, maintain the corrective effect, promote bone fusion, and prevent deformity recurrence.

[0003] For example, Chinese patent application CN216676052U discloses a lateral spinal deformity postoperative care brace. This device uses a dressing change device to change the patient's dressings, thereby speeding up the dressing change efficiency, reducing patient pain, and greatly reducing the possibility of the medication falling off immediately after application. When the patient needs ventilation, the patient can control the ventilation device to ventilate the inside of the device, avoiding adverse symptoms such as dampness, sores, and bacteria caused by wearing the device for a long time.

[0004] While existing spinal postoperative care braces can improve the convenience of dressing changes to some extent, the spine needs to maintain a certain physiological curve after surgery. To ensure the protective effect on the spine, the care brace needs to fit snugly against the outside of the spine to reduce the risk of secondary spinal deformation. However, different types of patients have different surgical sites and physiological curves. Existing care braces are difficult to fine-tune the bending angle and cannot make good contact with the outside of the spine, which will adversely affect the protective effect on the spine. Summary of the Invention

[0005] To address the problem that existing nursing braces are difficult to fine-tune in terms of bending angle and cannot make good contact with the lateral side of the spine, thus adversely affecting the protective effect on the spine, this invention provides a nursing brace for postoperative spinal deformity surgery that prevents secondary injury by setting several sets of parallel distributed cams to adjust the deformation range of the pads at different positions. This further improves the functionality and flexibility of the nursing brace during use.

[0006] To solve the above problems, the present invention adopts the following technical solution:

The toothed plate is slidably connected to the inner surface of the first guide groove.

[0012] Optionally, a pin is rotatably connected to the inner surface of the first guide groove, and a cam is fixedly connected to the outer surface of the pin. The outer surface of the cam contacts the outer surface of one side of the sealing plate. A gear is fixedly connected to the outer surface of the pin. The gear meshes with a gear plate for transmission. The number of gear plates and cams is equal and there are several groups of them, which are distributed in a parallel array. A positioning rod is engaged with the outer surface of the slide rod. Multiple positioning holes are embedded in the outer surface of one side of the support frame. The positioning holes penetrate into the interior of the second guide groove, and the positioning rod can engage with the positioning holes.

[0013] Optionally, the support frame is provided with a ventilation component on the outside. The ventilation component includes ventilation holes that penetrate through the outer surface of the support frame. The number of ventilation holes is several groups and they are distributed in a parallel array. The support frame is embedded with a folding groove. The folding groove has a V-shaped cross-section and there are two groups of folding grooves that are symmetrically distributed.

[0014] Optionally, a sealing sleeve is fixedly connected to the outer surface of one end of the folding groove. The outer surface of the sealing sleeve is arc-shaped and made of elastic material. An air guide groove is embedded in the outer surface of the other end of the support frame. An overflow groove is embedded in the support frame. One end of the overflow groove is connected to the inside of the air guide groove, and the other end extends into the inside of the folding groove. An air inlet hole is embedded in the outer surface of one end of the support frame.

[0015] Optionally, a relief component is provided on one side of the support frame. The relief component includes a groove embedded in the outer surface of one side of the support frame. An extrusion seat is slidably connected to the inner surface of the groove. The outer surface of the extrusion seat is wavy.

[0016] Optionally, the support frame is provided with fixing components on both sides.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above solution, by setting a shaping component, the elastic deformation of the sealing plate can push the traction rod, thereby rotating the traction rod and the ball at different angles. This helps to create different curvatures on the outer surface of the pad through the traction rod and the support seat. By setting several sets of parallel distributed cams, the deformation amplitude of the pad at different positions can be adjusted, thereby further improving the functionality and flexibility of the nursing brace during use.

[0019] This solution incorporates a shaping component. A movable sleeve encloses the outside of a sphere, allowing the sphere to rotate within the sleeve. This causes the sphere to adjust the angle of adjacent traction rods. During movement, the adjusting rod moves the support seat synchronously, enabling several sets of traction rods to form an angle with the support seat. Under the compression of the support seat, the pad undergoes elastic deformation, allowing it to contact the outside of the spine and shape it. This design supports the outside of the spine through the support seat, maintaining the spine's normal physiological curve and reducing the load on the spine to some extent.

[0020] This solution incorporates a breathable component. When the folding groove undergoes elastic deformation, the gas inside the folding groove will enter the air guide groove through the overflow groove under pressure. When the gas is injected into the air guide groove, it will be discharged outwards from within the air guide groove. The air flowing within the air guide groove not only cools and lowers the temperature of the surrounding skin, reducing the risk of infection and inflammation at the wound site, but also accelerates the airflow between the support frame and the patient's limb, thereby improving the breathability of the nursing brace during use.

[0039] like Figures 1 to 9As shown, this embodiment of the invention provides a postoperative nursing brace for spinal deformity surgery to prevent secondary injury, including a support frame 11. An installation groove 46 is embedded in the outer surface of one side of the support frame 11. A shaping component is provided inside the installation groove 46. The shaping component includes a sealing plate 35 fixedly connected to the inner surface of the installation groove 46. A plurality of support seats 31 are slidably connected to the outer surface of the sealing plate 35. A traction rod 32 is fixedly connected to each support seat 31. A movable sleeve 33 is fixedly connected to one end of the traction rod 32 protruding from the support seat 31. A ball 34 is rotatably connected inside the movable sleeve 33. A ball 34 is connected to the other end of the traction rod 32 protruding from the support seat 31. The ball 34 is covered by the movable sleeve 33, meaning that each traction rod 32 has a ball 34 at both ends. The end of a ball 34 not covered by the movable sleeve 33 is connected to one traction rod 32, and the end with the movable sleeve 33 is connected to another traction rod 32. Multiple spheres 34 are connected in a straight line in sequence by multiple traction rods 32, and each traction rod 32 is fitted with a support seat 31. The number of movable sleeves 33, spheres 34 and traction rods 32 are all in several groups and are distributed in an alternating array. The end of the traction rod 32 away from the movable sleeve 33 is fixedly connected to the sphere 34.

[0040] like Figures 1 to 6 As shown, the movable sleeve 33 is annular in shape, and a pad 30 is fixedly connected to one side of the mounting groove 46. The outer surfaces of the support base 31 and the movable sleeve 33 are both in contact with one side of the pad 30. The pad 30 and the sealing plate 35 are both made of flexible and breathable material, and the movable sleeve 33 and the ball 34 are made of lightweight and wear-resistant material. The outer surface of the support frame 11 is arc-shaped and made of lightweight material.

[0041] The support frame 11 has a first guide groove 36 embedded in the outer surface of one side where the mounting groove 46 is provided. The first guide groove 36 is located below the mounting groove 46 and is connected to the mounting groove 46. The sealing plate 35 is located between the first guide groove 36 and the mounting groove 46. A second guide groove 38 is embedded in the inner surface of the first guide groove 36. A slide rod 41 is slidably connected to the inner side of the second guide groove 38. A toothed plate 42 is fixedly connected to the outer surface of the slide rod 41. The toothed plate 42 is slidably connected to the inner surface of the first guide groove 36.

[0042] A pin 43 is rotatably connected to the inner surface of the first guide groove 36. A cam 44 is fixedly connected to the outer surface of the pin 43. The outer surface of the cam 44 contacts one side surface of the sealing plate 35. A gear 45 is fixedly connected to the outer surface of the pin 43. The gear 45 meshes with a toothed plate 42 for transmission. The number of toothed plates 42 and cams 44 are several sets and equal in number, arranged in a parallel array. Multiple cams 44 are evenly distributed along the length of the support frame 11. Multiple toothed plates 42 and multiple cams 44 are positioned correspondingly. A positioning rod 40 is engaged with one side outer surface of the slide rod 41. The positioning rod 40 is perpendicular to the slide rod 441. A positioning hole 37 is embedded in one side outer surface of the support frame 11. The positioning hole 37 extends into the second guide groove 38. The positioning rod 40 engages with the positioning hole 37 to position the slide rod 41.

[0043] like Figure 4 and Figure 6 As shown, the traction rods 32 located at both ends are provided with adjustment components. The adjustment components include adjustment rods 29 connected to one end of the traction rod 32. The adjustment rods 29 pass through the support frame 11 and extend to the outside of the support frame 11. A spiral sleeve 39 is fixedly connected to the inner surface of one end of the mounting groove 46. The inner surface of the spiral sleeve 39 is threadedly connected to the traction rod 32 connected to the adjustment rod 29 at the end.

[0044] By adopting the above technical solution, the support frame 11 is the main structure of the nursing brace. During use, the support frame 11 is fitted against the user's back, and its position is fixed. To improve the shaping and protective effect of the nursing brace on the postoperative spine and maintain the normal physiological curve of the spine, a shaping component is provided. An installation groove 46 is formed on the surface of the support frame 11 to hold the movable sleeve 33 and the ball 34. The pad 30 can seal the surface of the installation groove 46. The movable sleeve 33 wraps around the outside of the ball 34, allowing the ball 34 to rotate inside the movable sleeve 33. By adjusting the angle of the cam 44, the cam 44 is made to move upwards. The sealing plate 35 is pushed, causing it to undergo elastic deformation of varying degrees, which in turn drives the ball 34 to rotate. This causes the traction rod 32 connected to the ball 34 to adjust its angle, and also causes the traction rod 32 and the support seat 31 to move synchronously. This allows several sets of traction rods 32 to adjust their angle relative to the support seat 31. Under the compression of the support seat 31, the pad 30 undergoes elastic deformation, allowing it to contact the outer side of the spine and shape it. This allows the support seat 31 to support the outer side of the spine, maintaining its normal physiological curve, and also reducing the load on the spine to a certain extent.

[0045] When adjusting the traction rod 32 and the support base 31, the operator first removes the positioning rod 40 from the positioning hole 37, and then slides the slide rod 41 along the inside of the second guide groove 38. During the movement, the slide rod 41 drives the gear plate 42 to move synchronously. The pin 43 inside the first guide groove 36 supports the rotation of the gear 45. The gear 45 is connected to the gear plate 42 through meshing. As the gear plate 42 moves, it drives the gear 45 to rotate. During the rotation of the gear 45, it drives the pin 43 to rotate synchronously. The pin 43 drives the cam 44 to rotate at a certain angle. By rotating the cam 44 at different angles, different positions on the surface of the cam 44 can contact the outer surface of the sealing plate 35, thereby... The sealing plate 35 undergoes elastic deformation of varying degrees, which in turn pushes the traction rod 32, causing the traction rod 32 and the ball 34 to rotate at different angles. This helps to create different curvatures on the outer surface of the pad 30 through the traction rod 32 and the support seat 31. After the cam 44 is adjusted into position, the operator engages the positioning rod 40 into the positioning hole 37. The positioning rod 40, in conjunction with the positioning hole 37, limits the sliding rod 41, thus stabilizing the position of the cam 44. By setting several sets of parallel cams 44, the deformation amplitude of the pad 30 at different positions can be adjusted, thereby further improving the functionality and flexibility of the nursing brace during use.

[0046] Specifically, a sliding sleeve 47 is fixedly connected to one end of the inner surface of the mounting groove 46, a sliding plate 49 is slidably connected to the inner surface of the sliding sleeve 47, one end of the outer surface of the sliding plate 49 is fixedly connected to the end traction rod 32, and a spring 48 is fixedly connected to the side of the outer surface of the sliding plate 49 away from the traction rod 32. The spring 48 is fixedly connected to the inner surface of the sliding sleeve 47.

[0047] To adjust the rotational resistance of the ball 34, an adjustment component is provided. When it is necessary to increase the rotational resistance of the ball 34, the operator rotates the adjustment rod 29. During the movement of the adjustment rod 29, the connected traction rod 32 will rotate synchronously. The traction rod 32 is threadedly connected to the spiral sleeve 39. During the rotation, it will apply downward pressure to the ball 34. As the pressure increases, the resistance between the ball 34 and the movable sleeve 33 will also increase, thereby improving the rotational resistance of the ball 34 to a certain extent. This helps to improve the stability of the ball 34 and the traction rod 32. One end of the traction rod 32 will push the slide plate 49. The slide sleeve 47 will apply a certain elastic force to the slide plate 49 through the spring 48, thereby reducing the risk of damage caused by excessive pressure between the ball 34 and the movable sleeve 33. By setting up the adjustment component, the operational precision of the nursing brace during use can be further improved, which helps to improve the rehabilitation effect of the patient.

[0048] like Figure 3 and Figure 7As shown, a breathable component is provided on the outside of the support frame 11. The breathable component includes a breathable hole 12 that penetrates the outer surface of the support frame 11. The number of the breathable holes 12 is several groups and they are distributed in a parallel array. A folding groove 20 is embedded in the support frame 11. The folding groove 20 has a V-shaped cross-section and there are two groups of folding grooves 20 that are symmetrically distributed.

[0049] A sealing sleeve 21 is fixedly connected to the outer surface of one end of the folding groove 20. The outer surface of the sealing sleeve 21 is arc-shaped and made of elastic material. An air guide groove 13 is embedded in the upper surface of the support frame 11. An overflow groove 50 is embedded in the support frame 11. One end of the overflow groove 50 is connected to the inside of the air guide groove 13, and the other end extends into the inside of the folding groove 20. An air inlet hole 14 is embedded in the outer surface of one end of the support frame 11.

[0050] Nursing braces are worn for extended periods during use. To reduce the risk of pressure sores due to poor airflow between the support frame 11 and the skin, a breathable component is incorporated. The ventilation holes 12 on the surface of the support frame 11 improve airflow both inside and outside the frame. The folding grooves 20 on the inner side of the support frame 11 not only reduce the weight of the nursing brace to some extent, thus reducing discomfort during wear, but also allow for elastic deformation of the support frame 11 around the folding grooves 20 during patient movements such as turning over. A sealing sleeve 21 is used to seal the folding grooves 20. When the folding groove 20 undergoes elastic deformation, the internal volume of the folding groove 20 decreases. At this time, the gas inside the folding groove 20 will enter the air guide groove 13 through the overflow groove 50 under pressure. The air guide groove 13 is embedded in the outer surface of the support frame 11. When the gas is injected into the air guide groove 13, it will be discharged outward inside the air guide groove 13. The air flowing inside the air guide groove 13 can not only cool and reduce the temperature of the surrounding skin and reduce the risk of infection and inflammation at the wound site, but also accelerate the air flow between the support frame 11 and the patient's limb, thereby improving the breathability of the nursing brace during use.

[0051] like Figure 1 As shown, a relief assembly is provided on one side of the support frame 11. The relief assembly includes a groove 16 embedded in the outer surface of one side of the support frame 11. An extrusion seat 18 is slidably connected to the inner surface of the groove 16. The outer surface of the extrusion seat 18 is wavy. There are two sets of grooves 16 and extrusion seats 18, which are symmetrically distributed. An elastic band 17 is fixedly connected to the upper outer surface of the extrusion seat 18. The upper end of the elastic band 17 is fixedly connected to the upper end of the inner surface of the groove 16. A cable 19 is fixedly connected to the lower outer surface of the extrusion seat 18. The lower end of the cable 19 passes through to the lower side of the support frame 11 and slides in contact with the support frame 11.

[0052] The patient's movement is restricted during the wearing of the brace. Prolonged wear can lead to stiffness and atrophy of the back muscles. To address this, a relief component is designed. The groove 16 on the surface of the support frame 11 is used for sliding support of the compression seat 18. When relaxing the muscles around the spine, the user pulls down the cable 19, which causes the compression seat 18 to slide linearly within the groove 16. During this movement, the compression seat 18 comes into contact with the user's back skin. The surface of the compression seat 18 is wavy, which presses and relaxes the user's back skin during the movement, thereby alleviating discomfort during brace wearing to a certain extent and effectively improving the practicality of the nursing brace. As the compression seat 18 moves downward, it pulls the elastic band 17. When the operator releases the cable 19, the compression seat 18 moves in the opposite direction under the elastic force of the elastic band 17, thus restoring the compression seat 18 to its original position.

[0053] like Figure 3 and Figure 5 As shown, the support frame 11 is provided with fixing components on the left and right sides. The fixing components include traction grooves 15 embedded on both sides of the support frame 11. A traction block 22 is slidably connected to the inner side of the traction groove 15. A buffer groove 23 is embedded in the inner side of the traction block 22. An elastic plate 27 is fixedly connected to the inner surface of the buffer groove 23. A fixing plate 51 is fixedly connected to the outer surface of the elastic plate 27. A limit rod 24 and a top rod 26 are fixedly connected to the outer surface of the fixing plate 51. A limit hole 25 is embedded in the upper wall of the inner surface of the traction groove 15. The limit hole 25 is set along the length direction of the traction groove 15. The limit rod 24 and the limit hole 25 can engage and contact. The top rod 26 extends to the outside of the traction block 22. A strap 28 is fixedly connected to the outer surface of the traction block 22.

[0054] To allow for the binding and fixation of the support frame 11 at different positions, a fixing component is provided. A traction groove 15 on the surface of the support frame 11 is used for sliding support of the traction block 22. The traction block 22 can slide linearly within the traction groove 15. A strap 28 on the outer side of the traction block 22 can bind and fix the support frame 11, allowing for flexible adjustment of the binding position according to the spinal correction position to achieve better protective and therapeutic effects. When adjusting the position of the traction block 22, the operator presses the push rod 26 into the traction block 22, which will then be fixed... The plate 51 drives the limiting rod 24 to move synchronously, thereby causing the limiting rod 24 to disengage from the limiting hole 25 inside the traction groove 15. Then, the traction block 22 slides along the inside of the traction groove 15. When the traction block 22 moves to the appropriate position, the operator releases the top rod 26. At this time, the elastic plate 27 inside the buffer groove 23 will apply a certain elastic force to the fixed plate 51. The fixed plate 51 pushes the limiting rod 24 in the opposite direction, so that the limiting rod 24 is engaged in the limiting hole 25 to limit the position of the traction block 22, thereby enabling flexible adjustment of the position of the traction block 22 and the strap 28.

[0055] The workflow of the technical solution of this invention is as follows:

[0056] When using the nursing brace, the support frame 11 is placed against the user's back, and then the traction block 22 slides along the inside of the traction groove 15. The limiting rod 24 is pushed in the opposite direction by the fixing plate 51, so that the limiting rod 24 is engaged in the limiting hole 25 to limit the position of the traction block 22. The strap 28 on the outside of the traction block 22 can be used to tie and fix the support frame 11. By rotating the cam 44 at different angles, different positions of the cam 44 surface can contact the outer surface of the sealing plate 35, thereby causing the sealing plate 35 to produce elastic deformation of different amplitudes. The elastic deformation of the sealing plate 35 can push the traction rod 32, thereby causing the traction rod 32 and the ball 34 to rotate at different angles. This helps to create different curvatures on the outer surface of the pad 30 through the traction rod 32 and the support seat 31, so as to maintain the normal physiological curve of the spine. The traction rod 32 is threadedly connected to the spiral sleeve 39. During the rotation, it will push the ball The body 34 applies downward pressure. As the pressure increases, the resistance between the ball 34 and the movable sleeve 33 also increases, thereby increasing the rotational resistance of the ball 34 to a certain extent. This helps to improve the stability of the ball 34 and the traction rod 32. During the patient's limb movements such as turning over, the support frame 11 will produce a certain degree of elastic deformation with the folding groove 20 as the fulcrum. The gas inside the folding groove 20 will enter the air guide groove 13 through the overflow groove 50 under pressure. The air flowing inside the air guide groove 13 can cool and lower the surrounding skin. The compression seat 18 is driven by the cable 19 to slide linearly inside the slide groove 16. During the movement, the compression seat 18 will come into contact with the user's back skin. The surface of the compression seat 18 is wavy. During the movement, it will press and relax the user's back skin, thereby alleviating the discomfort during the wearing of the brace to a certain extent.
