Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to an adjustable orthopedic external fixator. Background Art
[0002] In the field of orthopedic treatment, the treatment of fractures and other injuries often relies on external fixators. However, there are many deficiencies in traditional products, which has promoted the research and development of new adjustable orthopedic external fixators.
[0003] On the one hand, traditional external fixators usually have fixed sizes and structures and are difficult to adapt to the physical differences of different patients. Since the bone morphologies, limb thicknesses, fracture sites, and types of patients vary, traditional fixators cannot accurately match the specific needs of each patient. For example, when using the same specification of external fixator for patients with different heights or patients with special fracture positions, situations such as insecure fixation or excessive compression may occur, which not only affects the treatment effect but may also cause increased pain for the patient and even lead to complications such as skin breakdown and poor blood circulation, prolonging the recovery period. On the other hand, during the fracture healing process, as the bones grow and recover, the external fixator often needs to be adjusted multiple times. However, the adjustment operation of traditional fixators is complex, requiring professional tools and a high level of skill, and it is difficult to ensure the adjustment accuracy. When medical staff make adjustments, they may not be able to accurately control the adjustment range, resulting in the fixator not being able to provide the optimal fixation force and angle for the fracture site, affecting the alignment and healing of the fracture ends and increasing the risk of malunion of the fracture. In addition, long-term use of external fixators can cause poor local blood circulation in the patient's limb and easy muscle atrophy, affecting the recovery of limb function. Traditional external fixators generally only have basic fixation functions and cannot provide adjuvant treatment for patients during the fixation process.
[0004] In view of this, the purpose of the present invention is to provide an adjustable orthopedic external fixator to solve the deficiencies existing in the prior art. Summary of the Invention

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to the attached Figure 1 - attached Figure 8, an embodiment of the present invention provides an adjustable orthopedic external fixator, which includes a first annular frame 1. Above the first annular frame 1, a second annular frame 2 is installed. Below the first annular frame 1, a third annular frame 3 is installed. A plurality of lighting beads 4 are installed on the inner sides of the plurality of annular frames, which are used to provide illumination when the patient uses it.

A fixing mechanism 8 is installed at the bottom of the adjusting mechanism 6. The fixing mechanism 8 includes a fixing component, a connecting component and a massage component, which are used to fix and massage the patient's feet.
[0023] The adjusting component in the adjusting mechanism 6 includes sliders 601 that are fixedly installed on the outer sides of the plurality of annular frames. On one side of the plurality of sliders 601, fixing plates 602 are installed. On one side of the plurality of fixing plates 602, sliding grooves 603 are opened.

Bolts 605 are installed in the plurality of positioning holes 604. A plurality of bolts 605 in the adjusting mechanism 6 are all connected to the plurality of sliders 601. Specifically, the sliders 601 provide a basis for movement during the entire adjustment process. Fixing plates 602 are installed on one side of the plurality of sliders 601. The fixing plates 602 not only play a role in connection and support, but the sliding grooves 603 opened on one side thereof enable the sliders 601 to freely slide on the fixing plates 602, thereby changing the relative positional relationship between the annular frames. On one side of the fixing plate 602, a plurality of positioning holes 604 are also opened. Bolts 605 are installed in the plurality of positioning holes 604. During actual adjustment, medical staff can loosen the bolts 605 according to the specific needs of the patient. At this time, the sliders 601 can freely slide in the sliding grooves 603. After adjusting to a suitable position, tighten the bolts 605 again to make them tightly connected to the sliders 601 and fix the annular frame in a new position. In this way, the size, shape and the angle between various parts of the external fixator can be flexibly adjusted to ensure that it can closely fit the patient's limb and provide the best fixation effect for the fracture site.
[0024] The guiding component includes a plurality of first telescopic rods 606 fixedly installed on the upper part of the first annular frame 1. The output ends of the plurality of first telescopic rods 606 are fixedly connected to the bottom of the second annular frame 2. A plurality of first telescopic rods 606 are fixedly installed at the bottom of the first annular frame 1.

A plurality of guiding rods 607 are installed between the upper and lower parts of the plurality of arc-shaped plates 5. Specifically, the output ends of multiple first telescopic rods 606 are fixedly connected to the bottom of the second annular frame 2. At the same time, multiple first telescopic rods 606 are also fixedly installed at the bottom of the first annular frame 1, and their output ends are fixedly connected to the upper part of the third annular frame 3. When the adjusting mechanism 6 adjusts the position or angle of the annular frame, the first telescopic rods 606 can prevent the second annular frame 2 and the third annular frame 3 from shifting or shaking. The guide rods 607 further enhance the structural stability. When adjusting the position of the annular frame, the guide rods 607 can guide the movement of the arc-shaped plate 5 to ensure that the positions of the telescopic mechanism 7 and the fixing needles 704 are always accurate and will not deviate due to adjustment, ensuring the reliability of the fixing effect and providing a strong guarantee for the stable fixation of the fracture site.
[0025] The auxiliary components in the telescopic mechanism 7 include two guide plates 701 installed on the inner side of the arc-shaped plate 5, and guide grooves 702 are provided on one side of each of the two guide plates 701; The second telescopic rod 703 in the telescopic mechanism 7 is installed between the two guide plates 701; Specifically, the second telescopic rod 703 in the telescopic mechanism 7 is installed between the two guide plates 701, and the guide grooves 702 provided on one side of the guide plates 701 provide a guiding function for the telescopic movement of the second telescopic rod 703, enabling it to perform telescopic movement stably.
[0026] The telescopic components include two second telescopic rods 703 installed on the inner side of the arc-shaped plate 5. The output ends of the second telescopic rods 703 are fixedly connected to fixing needles 704. A needle sleeve 705 is installed around the outer circumference of the fixing needles 704, and a sponge pad 706 is installed at one end of the fixing needles 704; Specifically, the needle sleeve 705 installed around the outer circumference of the fixing needles 704 can play a protective role to prevent unnecessary damage to the surrounding tissues during the insertion of the fixing needles 704, and at the same time can enhance the stability of the fixing needles 704. Also, the sponge pad 706 installed at one end of the fixing needles 704 can play a buffering role when contacting the patient's skin or bones.
[0027] The fixing components in the fixing mechanism 8 include a footrest plate 801 installed at the bottom of the entire device. A foot pedal hole 802 is provided on the upper part of the footrest plate 801. Clamping blocks 806 are installed on both sides of the upper part of the footrest plate 801, and a strap 807 is installed between the two clamping blocks 806; Specifically, the footrest plate 801 is used to support the patient's feet. There are footrest holes 802 opened on its upper part. The design of the footrest holes 802 conforms to the ergonomic principle, which can better fit the shape of the patient's feet and provide comfortable support. On both sides of the upper part of the footrest plate 801, there are snap blocks 806 installed. A strap 807 is installed between the two snap blocks 806. During use, medical staff place the patient's feet in the footrest holes 802, and then pass the strap 807 through the snap blocks 806, which can be adjusted according to the thickness of the patient's feet, and tightly fix the feet on the footrest plate 801 to ensure that the feet will not shake or displace during the treatment process, providing a stable foundation for subsequent fixation and treatment.
[0028] The connecting component includes a first connecting plate 803 installed on one side of two of the fixing plates 602. On the outer sides of one ends of the two first connecting plates 803, there are second bolts 804 installed. The two second bolts 804 are both connected to one side of the two fixing plates 602. One ends of the two first connecting plates 803 are both fixedly connected to both sides of the footrest plate 801. On one side of one of the fixing plates 602, a second connecting plate 808 is fixedly installed. One end of the second connecting plate 808 is fixedly connected to the footrest plate 801. Specifically, the first connecting plate 803 installed on one side of two of the fixing plates 602. On the outer sides of one ends of the two first connecting plates 803, there are second bolts 804 installed. The two second bolts 804 are both connected to one side of the two fixing plates 602. One ends of the two first connecting plates 803 are both fixedly connected to both sides of the footrest plate 801. At the same time, a second connecting plate 808 is fixedly installed on one side of one of the fixing plates 602, so that the first connecting plate 803 can be firmly fixed on the fixing plate 602, ensuring that the fixing effect on the patient's feet is not affected.
[0029] The massage component includes a plurality of massage bumps 805 installed inside the footrest holes 802, and air-filled cushions 809 are installed on both sides inside the footrest holes 802. Specifically, the soles of the patient's feet can be massaged through the plurality of massage bumps 805 installed inside the footrest holes 802, thereby stimulating the acupoints on the soles of the feet, promoting blood circulation, and relieving foot fatigue caused by long-term fixation. When the air-filled cushions 809 are inflated, they will generate a certain pressure on both sides of the patient's feet, playing a role in massage and support, and further promoting blood circulation in the feet.
[0030] Working principle: During actual use, medical staff first place the patient's feet in the footrest holes 802 of the footrest plate 801, and initially fix the feet through the snap blocks 806 and the strap 807 on both sides of the upper part of the footrest plate 801. At the same time, the strap 807 can be adjusted according to the thickness of the patient's feet to ensure the stability of the fixation, avoiding shaking or displacement of the feet during the treatment process, and providing a stable foundation for subsequent fixation and treatment.
[0031] After fixation, it is installed between two guide plates 701 through the second telescopic rod 703 in the telescopic mechanism 7. The guide groove 702 opened on one side of the guide plate 701 provides guidance for the telescopic movement of the second telescopic rod 703, enabling it to perform telescopic movement stably. When it is necessary to fix the fracture site, the output end of the second telescopic rod 703 pushes the fixing needle 704 to extend outwards. At the same time, the needle sleeve 705 installed around the outside of the fixing needle 704 can play a protective role to prevent unnecessary damage to the surrounding tissues during the insertion of the fixing needle 704, and can also enhance the stability of the fixing needle 704. Also, the sponge pad 706 installed at one end of the fixing needle 704 can play a buffering role when contacting the patient's skin or bone, reducing the patient's pain. Moreover, the sponge pad 706 can also absorb the liquid exuded from the wound, keeping the local area clean and contributing to the wound healing. Finally, the fixing needle 704 is accurately inserted into the appropriate position to achieve the auxiliary fixation of the fracture site, helping the fracture site to maintain the correct position and promoting healing.
[0032] During the fixation process, when it is necessary to adjust the position and angle of the device, the adjustment component in the adjustment mechanism 6 includes sliders 601 installed on the outside of multiple annular frames, and the sliders 601 are connected to the fixed plate 602. Also, a chute 603 is opened on one side of the fixed plate 602, so that the sliders 601 can slide in the chute 603. At the same time, by loosening the first bolt 605, the sliders 601 can freely slide in the chute 603, thereby adjusting the relative position between the annular frames. When adjusted to the appropriate position, by tightening the first bolt 605, it is tightly connected to the sliders 601 to fix the annular frame in the new position, so as to flexibly adjust the size and shape of the external fixation bracket according to the specific conditions of the patient's fracture site and the changes during the treatment process, ensuring that it can closely fit the patient's limb and provide the best fixation effect.
[0033] The guiding component in the adjustment mechanism 6 provides stable guidance and support for the adjustment process. Also, the first telescopic rods 606 are installed on the upper and lower parts of the first annular frame 1, and their output ends are respectively fixedly connected to the bottom of the second annular frame 2 and the upper part of the third annular frame 3. At the same time, the first telescopic rods 606 can not only support different annular frames, but also ensure the relative position stability between the annular frames during the adjustment process, preventing deviation or shaking. Moreover, the guiding rods 607 installed between the upper and lower parts of the multiple arc-shaped plates 5 further enhance the structural stability. When adjusting the position of the annular frame, the movement of the arc-shaped plates 5 can also be guided by the guiding rods 607, so as to ensure that the positions of the telescopic mechanism 7 and the fixing needle 704 always remain accurate and will not deviate due to adjustment, ensuring the reliability of the fixation effect.
[0034] During the treatment process, the massage component of the fixing mechanism 8 can provide adjuvant treatment for the patient. The sole of the patient can be massaged through multiple massage bumps 805 installed inside the foot pedal hole 802, thereby stimulating the acupoints on the sole of the foot, promoting blood circulation, and relieving foot fatigue caused by long-term fixation. Also, the air bags 809 on both sides inside the foot pedal hole 802 can be inflated or deflated as needed. When the air bags 809 are inflated, a certain pressure will be exerted on both sides of the patient's foot, playing a role in massage and support, further promoting blood circulation in the foot, and at the same time, better fixing the foot to prevent it from moving on the footrest plate 801. Finally, through the synergistic effect of the massage bumps 805 and the air bags 809, while the patient is receiving fracture treatment, the comfort of the foot is improved, which helps to improve the patient's treatment compliance.
[0035] When examining the patient, changing the dressing around the fixing needle 704, or observing the wound condition, by turning on the lighting bead 4, sufficient lighting can be provided, enabling medical staff to clearly see the treatment site, improving the accuracy and safety of the operation, avoiding operation errors caused by insufficient light, and helping to better carry out the treatment and nursing work.
[0036] In summary, the fixing mechanism 8 is used to fix the patient's foot, and the telescopic mechanism 7 is used to achieve auxiliary fixation of the fracture site. At the same time, the adjustment mechanism 6 flexibly adjusts the position and angle of the device according to the treatment requirements. Then, the massage component relieves foot fatigue and promotes blood circulation. Finally, the lighting bead 4 provides lighting assistance. Each component cooperates with each other to jointly provide comprehensive and effective support for the patient's fracture treatment, improving the treatment effect and the patient's comfort.
