Detailed Implementation

[0027] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] A specific embodiment of the present invention, such as Figure 1 As shown, a support device for orthopedic surgery is disclosed, including a hip support unit and a foot support unit 3. The foot support unit 3 is provided with a foot support plate 31 and an angle adjustment component 32, which is used to adjust the angle of the foot support plate 31.

[0029] To address the issue that the fixed angle of the foot support unit 3 cannot adapt to the patient's treatment and rehabilitation posture requirements, this embodiment incorporates a foot support plate 31 and an angle adjustment component 32 within the foot support unit 3. The angle adjustment component 32 adjusts the support angle of the foot support plate 31, allowing for flexible adjustment of the foot support angle according to the patient's treatment and rehabilitation posture needs. This ensures the patient's lower limbs are in a natural, relaxed physiological posture, reducing the risk of muscle tension, fatigue, and abnormal force caused by fixed or rough adjustment of the support angle. It also improves comfort and postural stability during treatment and rehabilitation, enhancing adaptability and versatility for patients with different conditions.

[0030] Specifically, this embodiment also includes a support unit 4, which includes a base 41 and a support rod 42. The base 41 has a frustum structure and is placed on the floor of the operating room.

[0031] The support rod 42 is located on the upper part of the base 41 and is used to support the hip support unit, the foot support unit 3 and the distance adjustment unit 2.

[0032] like Figure 4 As shown, the hip support unit includes a hip support plate 1, which is an L-shaped flat plate. One end of the hip support plate 1 supports the hips, and the other end extends along the patient's leg towards the foot, forming a leg support. It should be noted that in this embodiment, the width of the end supporting the hips is greater than the width of the extension, thus providing space for the distance adjustment unit 2. A rubber pad is provided on the inner side of the hip support plate 1, which contacts the patient's body to improve patient comfort.

[0033] like Figure 5 As shown, the distance adjustment unit 2 includes a connecting plate 21 and a first connecting member 22. The connecting plate 21 is located below the leg of the hip support plate 1, and its end away from the hip support plate 1 is connected to the foot support unit 3. One end of the first connecting member 22 is located on the hip support plate 1, and the other end is located on the connecting plate 21.

[0034] Specifically, two first connecting members 22 are provided. The first connecting member 22 has an L-shaped structure, with one end fixed to the hip support plate 1 by bolts, and the other end equipped with a pin 221. A long, narrow guide hole 211 extending along the length of the connecting plate 21 is provided in the middle of the connecting plate 21. The pin 221 of the first connecting member 22 passes through the long, narrow guide hole 211 and moves within it. The connecting plate 21 can move to the opposite side of the hip support plate 1 to decrease or increase the distance between the foot support unit 3 and the hip support plate 1, thereby adapting to the length of the patient's leg. After the connecting plate 21 is adjusted to its correct position, a nut is installed on the side of the pin 221 opposite to the first connecting member 22 to lock the position of the connecting plate 21.

[0035] Furthermore, the distance adjustment unit 2 also includes a gear 23 and a rack 24. For example... Figure 3 As shown, gear 23 is rotatably mounted on the leg of the hip support plate 1, and gear 23 is sleeved on the outside of gear 23 shaft. Rack 24 is disposed on the upper edge of connecting plate 21, and rack 24 meshes with gear 23. Rotating gear 23 can drive rack 24 and connecting plate 21 to move to the opposite side or the opposite side of hip support plate 1, so that the distance between foot support unit 3 and hip support plate 1 decreases or increases, adapting to the length of the patient's leg.

[0036] To address the issue of limited or inaccurate adjustment of the distance between the foot and buttocks, which cannot accommodate patients with different leg lengths, this embodiment employs a pin 221 and guide hole 211 structure for coarse adjustment of the position of the connecting plate 21 and foot support unit 3, and a gear 23 and rack 24 structure for precise adjustment of the position of the connecting plate 21 and foot support unit 3. In use, coarse adjustment is first performed to position the foot support unit 3 approximately at the patient's foot, followed by fine adjustment to achieve the precise position of the foot support unit 3 at the patient's foot. This improves adjustment efficiency and accuracy, enhances patient comfort, saves time for medical staff, and facilitates surgical procedures.

[0037] Furthermore, such as Figure 2 As shown, it also includes a guard plate 25, which is disposed on the outside of the connecting plate 21 and is used to support the gear 23 and the gear 23 shaft. The other end of the gear 23 shaft is rotatably disposed on the guard plate 25, and the pin 221 of the first connecting member 22 passes through the guard plate 25.

[0038] It should be noted that bearings (not shown in the figure) are provided at the connection between the gear 23 shaft and the hip support plate 1 and the guard plate 25 to support the gear 23 shaft.

[0039] like Figure 5As shown, the foot support unit 3 includes a foot support plate 31 and an angle adjustment assembly 32. A second connecting rod 3233 is also provided on the second adjustment plate 323. The first connecting rod 3232 and the second connecting rod 3233 are used to connect with the foot support plate 31.

[0040] To address the problem of the fixed and unadjustable angle of the foot support plate in the prior art, an angle adjustment component 32 is mounted on the connecting plate 21 and connected to the foot support plate 31. The angle adjustment component 32 can adjust the angle of the foot support plate 31 to meet the foot angle requirements during surgery.

[0041] The angle adjustment assembly 32 includes a rotating shaft 321, a first adjusting plate 322, and a second adjusting plate 323. The rotating shaft 321 is rotatably mounted on the connecting plate 21. The first adjusting plate 322 is connected to the rotating shaft 321 and drives the rotating shaft 321 to rotate. One end of the second adjusting plate 323 is connected to the foot support plate 31, and the other end of the second adjusting plate 323 is connected to the rotating shaft 321. Specifically, the second adjusting plate 323 is connected to the foot support plate 31 via the rotating shaft 321 and a connecting rod. The first adjusting plate 322 drives the rotating shaft 321 to rotate, causing the second adjusting plate 323 and the foot support plate 31 to rotate together.

[0042] Furthermore, to address the stability issue of locking after the foot support plate angle is adjusted, a second connecting member 324 is included. One end of the second connecting member 324 is hinged to the connecting plate 21, and the other end is provided with a guide pin 3241. An arc-shaped groove 3221 is provided in the middle of the first adjusting plate 322, and the guide pin 3241 passes through the arc-shaped groove 3221 and can move along the length direction of the arc-shaped groove 3221, driving the second connecting member 324 to swing around its hinge point with the connecting plate 21.

[0043] The edge of the second adjusting plate 323 is also provided with a fan-shaped plate 3231, which has a toothed structure. One side of the second connecting member 324 is provided with fan-shaped teeth. When the second connecting member 324 swings, the fan-shaped teeth can disengage or engage with the toothed structure to unlock or lock the rotation state of the first adjusting plate 322.

[0044] Furthermore, to address the issue of resetting the foot support plate after angle adjustment, the angle adjustment assembly 32 also includes a return spring 325 and a torsion spring 326. A first connecting post 3222 is provided on the first adjustment plate, and a second connecting post 327 is provided on the connecting plate 21. The return spring 325 is positioned between the first connecting post 3222 and the second connecting post 327 for the rotational reset of the first adjustment plate 322. The torsion spring 326 is mounted on the rotating shaft 321, with its other end connected to a first connecting rod 3232 on the second adjustment plate 323 for the reset of the second adjustment plate 323 and the foot support plate 31.

[0045] To address the issues of difficulty in adjusting the foot angle adjustment component 32 and its stability after adjustment, this embodiment rotatably mounts the rotating shaft 321 onto the connecting plate 21, connecting both the first adjusting plate 322 and the second adjusting plate 323 to the rotating shaft 321. The other end of the second adjusting plate 323 is connected to the foot support plate 31, ensuring that the rotation of the first adjusting plate 322 stably drives the second adjusting plate 323 and the foot support plate 31 to rotate synchronously, thus achieving adjustable angle of the foot support plate 31. The locking and unlocking of the rotation state is achieved through the toothed structure of the fan-shaped plate 3231 of the second adjusting plate 323 and the fan-shaped teeth of the second connecting member 324. The engagement is reliable, the locking state is stable, and it is not easy for loosening, slippage, or skipping teeth to occur, effectively ensuring the support stability and safety of the foot support plate 31 at the set angle.

[0046] Furthermore, such as Figure 6 As shown, the foot support unit 3 also includes a base 33. The base 33 is disposed at the lower part of the foot support plate 31. Side plates are provided on both sides of the foot support plate 31, and guide grooves 311 are provided on the side plates. Protrusions are provided at both ends of the base 33. The protrusions can slide in the guide grooves 311 to adjust the position of the base 33 to adapt to the length of the feet of different patients.

[0047] To improve patient comfort, the foot support unit 3 also includes an arc-shaped rubber plate 34, which is located in the middle of the foot support plate 31 and is used to support the arch of the patient's foot.

[0048] Furthermore, to accommodate the arch curvature of different patients' feet, the curved rubber plate 34 is also equipped with an arch adjustment structure 35. For example... Figure 6 and Figure 7 As shown, the arc adjustment structure 35 is disposed on the foot support plate 31 and includes a movable strip 351 and a fixed strip 352. Exemplarily, the fixed strip 352 is located at one end near the base 33, and the movable strip 351 is located at the end away from the base 33. The two ends of the arc-shaped rubber plate 34 are respectively disposed on the fixed strip 352 and the movable strip 351. When the movable strip 351 moves towards the fixed strip 352, the distance between the two ends of the arc-shaped rubber plate 34 decreases, the arc of the arc formed in the middle decreases, and the curvature of the arc increases, which is suitable for patients with a large arch in their feet.

[0049] The foot support plate 31 has grooves 312 along the length of the foot support plate 31 near the side plates on both sides. The movable bar 351 has sliders 353 at both ends. The sliders 353 extend into the grooves 312 and can slide in the grooves 312, thereby driving the movable bar 351 to slide.

[0050] Furthermore, to fix the state after the curvature adjustment, fixing elongated holes 313 are respectively provided on the two side plates of the foot support plate 31. It can be understood that the length direction of the fixing elongated hole 313 is the same as the length direction of the slide groove 312, the fixing elongated hole 313 communicates with the slide groove 312, and a fixing bolt 354 is provided in the fixing elongated hole 313. A threaded hole is provided on one side of the slider 353, and the fixing bolt 354 can extend into the threaded hole to fix the slider 353, thereby locking the movable strip 351 and thus locking the bending state of the arc-shaped rubber plate 34.

[0051] To address the issue that existing support devices do not consider the different arch structures of patients, the curvature adjustment structure 35 of this embodiment, through the cooperation of the movable strip 351, the fixed strip 352, and the arc-shaped rubber plate 34, combined with the sliding guide of the slider 353 and the groove 312, can flexibly and precisely adjust the curvature of the arc-shaped rubber plate 34 to adapt to different patient arch shapes, solve the problem of uneven force distribution in existing supports, improve comfort, and reduce the risk of limb injury. The adjustment process is smooth and without jamming, with reliable positioning, convenient operation, and quick adaptation.

[0052] Furthermore, a removable rubber pad is provided on the upper part of the foot support plate 31.

[0053] The usage method of this embodiment is as follows: Place the hip support plate 1 on one side of the patient's hip.

[0054] Adjust the connecting plate 21 toward / away from the patient's leg length until the foot support plate 31 is near the patient's foot. Rotate the gear 23 shaft for fine adjustment. The rack 24 moves the connecting plate 21 and the foot support plate 31 toward / away from the buttocks until the foot support plate 31 is exactly at the patient's foot.

[0055] Place the patient's arch on the arched rubber plate, adjust the movable strip 351 to match the curvature of the arched rubber plate to the patient's arch, and thread the bolt through the fixing elongated hole 313 and screw it into the threaded hole of the slider 353 to lock the curvature of the arched rubber plate.

[0056] Adjust the tilt angle of the foot support plate 31. Press / lift the end of the first adjustment plate 322 away from the rotating shaft 321 downwards / upwards. The first adjustment plate 322 drives the rotating shaft 321 and the foot support plate 31 to rotate downwards / upwards. At this time, the fan-shaped teeth of the second connector 324 disengage from the toothed structure of the second connector 324. After reaching the required angle for the operation, release the first adjustment plate 322. The return spring 325 drives the first adjustment plate 322 downwards, and the fan-shaped teeth press against the toothed structure, locking the adjustment angle of the foot support plate 31.

[0057] Complete the adjustment of the support device.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
