Description

Technical Field

[0001] The present invention relates to the technical field of fracture correction and fixation, and in particular to a fixation device for correcting fracture deformities of hands and feet. Background Art

[0002] Fractures usually require external fixation treatment, generally to maintain the joint in a stable environment, to ensure that the fracture ends are not subjected to excessive force, and to facilitate bone healing. If the patient does not undergo external fixation treatment after a fracture, the fracture ends will move slightly under force, making it difficult for the callus to grow. Generally, fracture external fixation includes external fixators, plaster fixation, and small splint fixation.

[0003] Currently, patent document No. 202310367794.4 proposes a fixation device for correcting fracture deformities of the hands and feet. The device comprises a sleeve with a plurality of evenly distributed airbags fixedly installed inside the sleeve. The airbags are sealed and fixedly connected to each other. The outer side of the sleeve can cover uncured calcite. Both ends of the sleeve are provided with an annular seat fixedly and sealed therewith. The inner side of the annular seat is provided with an annular airbag fixedly and sealed therewith. The calcite covered on the outer side of the sleeve will fix and support the sleeve after curing. After the annular airbags and the airbags are inflated, they can be fixed to the hand or foot with the fracture. When the patient has a mild fracture, directly using plaster to fix it will affect the blood circulation of the patient's plastered area and is not conducive to the patient's recovery. Therefore, splints and bandages are used for fixation and correction. The bandages are tied to the injured part of the patient by binding, thereby fixing the fracture site. However, due to the certain softness of the bandages, the splint may be accidentally displaced, affecting the fixation effect of the splint and causing inconvenience in use. Summary of the Invention

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Example 1

[0029] like Figures 1 to 5As shown, the present embodiment is a fixation device for correction of fracture deformity of hands and feet, comprising a wearing ring 1, which is used to be worn on the patient's hand or leg, so as to realize wearing of the device. There are two wearing rings 1, and four fixing plates 2 are installed in a circular array between the two wearing rings 1. The fixing plate 2 is used to connect and fix the two wearing rings 1, and provides a carrier for the installation of the correction plate 6. A guide rod 3 is movably installed on the middle part of the upper end of the fixing plate 2 through a through hole, and a connecting plate 1 4 is installed on the lower end of the guide rod 3. A connecting plate 2 5 is hingedly installed on the lower end of the connecting plate 1 4, and a correction plate 6 is installed on the lower end of the connecting plate 2 5. The correction plate 6 drives the guide rod 3 to move up and down on the fixing plate 2 through the connecting plate 1 4 and the connecting plate 2 5, so that the position of the correction plate 6 can be adjusted according to the thickness of the fracture patient's hand or leg, and the connecting plate 1 4 and the connecting plate 2 5 are connected. Under the action of , the correction plate 6 can be adjusted in angle, which is convenient for adjusting the correction angle of the correction plate 6 according to the hand or leg, and although the connecting plate 1 4 and the connecting plate 2 5 are connected in a hinged manner, when adjusting the combined angle of the connecting plate 1 4 and the connecting plate 2 5, a certain force needs to be applied to adjust it, so there will be no accidental rotation. A limit adjustment component is installed on the upper end of the correction plate 6, and the limit adjustment component is used to fix the correction plate 6 after the angle is adjusted. By using the limit adjustment component to adjust and clamp the angles of the four correction plates 6, the hands and feet of the fractured patient can be corrected and clamped without accidental movement, and the correction clamping effect is good. An annular airbag 8 is installed inside the wearing ring 1, and the annular airbag 8 is used to fill the gap between the wearing ring 1 and the legs and hands of the fractured patient, so as to achieve effective wearing of the wearing ring 1.

[0030] Specifically, the limit adjustment assembly includes a mounting block 701, an adjusting screw 702, a connecting plate three 703, a connecting plate four 704, a limit knob 705 and a moving rod 706. The fixing plates 2 on both sides of the guide rod 3 are rotatably mounted with mounting blocks 701. The upper end of one mounting block 701 is threadedly connected to the adjusting screw 702 through a screw hole. The upper end of the other mounting block 701 is penetrated by a through hole and a moving rod 706 is installed. The lower ends of the adjusting screw 702 and the moving rod 706 are both installed with the connecting plate three 703. The connecting plate 3 703 is rotatably mounted on the lower end of the adjusting screw 702 through a bearing. Two connecting plates 4 704 are installed on both sides of the upper end of the correction plate 6. The two connecting plates 4 704 and the connecting plate 3 703 are hinged. A threaded groove is arranged on the upper end surface of the moving rod 706. The surface of the moving rod 706 is threadedly connected to the limit knob 705 at the upper end of the mounting block 701. The adjusting screw 702 is rotated by rotating the adjusting screw 702. The adjusting screw 702 drives one end of the correction plate 6 to rotate through the connecting plates 3 703 and the connecting plates 4 704. When the correction plate 6 is adjusted to a suitable angle, the limit knob 705 is installed on the moving rod 706 to adjust and fix the angle of one correction plate 6. The four correction plates 6 can be effectively clamped according to the actual situation of the fracture of the hand or leg of the fracture patient, thereby clamping and fixing the fracture. In actual use, although the connecting plate three 703 and the connecting plate four 704 are rotatably connected by a hinge, there is a certain damping between the connecting plate three 703 and the connecting plate four 704. When adjusting the combined angle of the connecting plate three 703 and the connecting plate four 704, a certain force needs to be applied. Therefore, after the correction plate 6 is fixed to the fracture patient, it will not move easily, and the connecting plate three 703 below the adjusting screw 702 can be rotated, so the connecting plate three 703 will not rotate with the adjusting screw 702.

[0031] Furthermore, the upper ends of the fixed plates 2 on both sides of the guide rod 3 are provided with rotation grooves 9, which are square in shape. The mounting block 701 can be rotated inside the rotation groove 9 to facilitate the correction plate 6 to be at a suitable angle. In actual use, when the angle of the correction plate 6 is adjusted, the mounting block 701 can be rotated inside the rotation groove 9 to facilitate the correction plate 6 to be at various angles. The front and rear ends of the mounting block 701 are both equipped with support rods 10, and one end of the support rods 10 is equipped with a ball 11. The front and rear ends of the part are both provided with card slots 12, and the card slots 12 are semicircular. The spheres 11 are respectively located inside the card slots 12. The mounting block 701 drives the spheres 11 to rotate inside the card slots 12 through the support rod 10, thereby realizing the rotation function of the mounting block 701. The mounting block 701 is located inside the rotating groove 9. The size of the mounting block 701 is much smaller than the size of the rotating groove 9. When the mounting block 701 rotates inside the rotating groove 9, the mounting block 701 will not come into contact with the rotating groove 9, which facilitates the effective rotation of the mounting block 701.

[0032] Furthermore, the four corrective plates 6 are all installed with skin-friendly silicone layers 13 on their opposite surfaces. The skin-friendly silicone layer 13 has good air permeability. The skin-friendly silicone layer 13 has a soft, delicate and elastic texture achieved through special production technology and formula adjustment. This material not only feels natural, but also has good air permeability and moisture-wicking properties, effectively avoiding the stuffiness and discomfort that may occur when in contact with the skin for a long time. The open porous structure of the skin-friendly silicone layer 13 also helps to dissipate moisture, providing good ventilation conditions, avoiding discomfort at the contact point between the corrective plate 6 and the patient's skin, and effectively ensuring the comfort of the surrounding skin when the corrective plate 6 corrects the fracture.

[0033] Furthermore, the wearing ring 1 is composed of a lower half ring 101 and an upper half ring 102, and the number of fixed plates 2 on the lower half ring 101 and the upper half ring 102 is two. The lower half ring 101 and the upper half ring 102 are both semicircular, and one end of the lower half ring 101 and the upper half ring 102 are rotatably connected by a hinge, and the upper half ring 101 and the upper half ring 102 are rotatably connected by a hinge. By rotating the lower half ring 101, the lower half ring 101 can be combined with the upper half ring 102 in the form of a flip, thereby realizing the combination of the lower half ring 101 and the upper half ring 102, which is convenient for fracture patients to wear the wearing ring 1.

[0034] Furthermore, a connecting piece 14 is installed at the other end of the lower half ring 101, and a connecting groove 15 is arranged on the surface of the upper half ring 102. The connecting piece 14 is installed inside the connecting groove 15 through a connecting bolt 16, and the connecting bolt 16 extends to the inside of the upper half ring 102. When the lower half ring 101 is flipped over, the lower half ring 101 drives the connecting piece 14 into the connecting groove 15, and then the connecting bolt 16 on the connecting piece 14 is rotated to install the connecting piece 14 inside the connecting groove 15, thereby achieving the fixation of the combination of the lower half ring 101 and the upper half ring 102, avoiding accidental rotation of the upper half ring 102 and the lower half ring 101 when the wearing ring 1 is used, thereby avoiding affecting the wearing effect of the wearing ring 1.

[0035] Furthermore, both the lower half ring 101 and the upper half ring 102 are provided with mounting cavities 23, and the annular airbag 8 is mounted inside the mounting cavity 23 on the upper half ring 102. An air nozzle 17 is mounted on the annular airbag 8, and the air nozzle 17 extends to the outside of the upper half ring 102. When wearing the wearing ring 1, the fracture patient can directly insert his hand or leg into the annular airbag 8, and then rotate the lower half ring 102 to combine the upper half ring 102 and the lower half ring 101. During this process, the annular airbag 8 enters the mounting cavity 23 in the lower half ring 101, and the air nozzle 17 is inflated to expand the annular airbag 8. The expanded annular airbag 8 can fill the gap between the patient's hand or leg and the wearing ring 1, making it easier for the patient to wear the ring effectively and ensuring the patient's comfort when wearing the wearing ring 1. During actual use, the annular airbag 8 contacts the patient's skin surface, effectively preventing the wearing ring 1 from accidentally moving, and playing a positioning role in the wearing position of the wearing ring 1.

[0036] The method of using this embodiment is as follows: first, flip the lower half ring 101 to expose the annular airbag 8 to the outside, then wear the annular airbag 8 on the patient's hand or leg, then adjust the position of the correction plate 6 so that multiple correction plates 6 are located at the position where the patient needs fracture correction and fixation, then turn the adjustment screw 702 in the limit adjustment assembly, and the adjustment screw 702 drives one end of the correction plate 6 to descend through the connecting plate three 703 and the connecting plate four 704, while the guide rod 3 drives the correction plate 6 to move up and contact the skin of the fracture patient, so that the correction plate 6 maintains a suitable angle, and contacts the correction plate 6 with the part of the patient's fracture that needs correction, then install the limit knob 705 on the moving rod 706 to adjust and fix the angle of one correction plate 6, repeat the above steps to adjust the four correction plates 6, and the four correction plates 6 can effectively clamp the fracture injury of the patient, thereby achieving a correction effect. The skin-friendly silicone layer 13 on the correction plate 6 is made of special The production process and formula are adjusted to achieve a soft, delicate and elastic texture. This material not only feels natural, but also has good air permeability and moisture dissipation, effectively avoiding the stuffiness and discomfort that may occur when in contact with the skin for a long time. The open porous structure of the skin-friendly silicone layer 13 also helps to dissipate moisture, providing good ventilation conditions, and avoiding discomfort at the contact point between the correction plate 6 and the patient's skin. Then rotate the lower half ring 101 so that the connecting piece 14 at one end of the lower half ring 101 enters the connecting groove 15 on the upper half ring 102, and use the connecting bolt 16 to fix the connecting piece 14 inside the connecting groove 15 to achieve the connection and fixation of the lower half ring 101 and the upper half ring 102. Then, inflate the annular airbag 8 through the air nozzle 17. The annular airbag 8 fills the gap between the wearing ring 1 and the patient's fracture site to achieve the wearing of the wearing ring 1. In actual use, the annular airbag 8 plays a positioning role in the wearing of the wearing ring 1, effectively ensuring the comfort of the wearing ring 1 when wearing.

[0037] Example 2

[0038] The structure of the fixation device for correcting fractures and deformities of the hands and feet of this embodiment is basically the same as that of the fixation device for correcting fractures and deformities of the hands and feet of embodiment 1, except that: two limit blocks 18 are installed at the lower end of the lowest fixing plate 2, and the limit block 18 is located between the guide rod 3 and the mounting block 701. A mounting groove 19 is arranged on the limit block 18, and a fixing belt 20 is detachably installed inside the mounting groove 19. A connecting belt 21 is installed between the two fixing belts 20, and a sling belt 22 is installed at the upper end of the connecting belt 21. By installing the fixing belt 20 inside the mounting groove 19 inside the limit block 18, the connecting belt 21 connects the two fixing belts 20, and then the sling belt 22 is hung on the patient's neck. When correcting a fracture of the arm, the patient's arm can be suspended, and the arm can be effectively fixed to avoid accidental movement of the arm during the correction of the arm fracture. The setting of the mounting groove 19 plays a positioning role in the installation of the fixing belt 20, and avoids accidental movement of the fixing belt 20 on the surface of the fixing plate 2 (see Figure 6 and Figure 7 ).

[0039] Specifically, the fixing strap 20 is detachably mounted inside the mounting slot 19 by means of Velcro. The fixing strap 20 is mounted inside the mounting slot 19 by means of Velcro. In actual use, the fixing strap 20 can be removed when correcting and fixing the leg bones. When correcting the arm bones, the fixing strap 20 and the sling strap 22 need to be installed, so that it is convenient to choose whether to use the sling strap 22 according to the actual fracture site of the patient. In actual use, the length of the sling strap 22 can be adjusted according to the distance between the patient's arm and neck. The actual use length of the sling strap 22 is adjusted by knotting or buckling, so as to realize the effectiveness of the sling strap 22 in suspending the entire device.

[0040] The method of use of this embodiment is as follows: when fixing the fractured part of the hand, the arm suspension belt 22 needs to be installed. First, the fixing belt 20 is sleeved on the surface of the four fixing plates 2, and the fixing belt 20 is installed in the installation groove 19 inside the limit block 18 through Velcro. The limit block 18 can prevent the fixing belt 20 from accidentally moving on the surface of the fixing plate 2. After completing the installation of the fixing belt 20, the arm suspension belt 22 is then hung on the patient's neck, and then the length of the arm suspension belt 22 is adjusted. The injured and fractured arm can be suspended, which helps the fractured arm to recover quickly.

[0041] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalent features for some of the technical features.
