Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic medical devices, and more specifically to an orthopedic splint installation and fastening device for orthopedics. Background Art

[0002] In orthopedic treatment, fracture is a common injury. In order to promote the healing of the fracture site, an orthopedic splint is usually required for fixation. Traditional orthopedic splint installation and fastening equipment has certain limitations in practical applications.

[0003] In the existing orthopedic splint installation and fastening devices, two fixing plates close to each other are usually arranged in parallel. This design seems reasonable in theory, but it exposes many problems in practical applications. The limbs of the human body are not standard cylindrical, but have complex and diverse shapes. The limb shapes of different patients are significantly different. For example, some patients may have swelling at the fracture site, resulting in irregular local shapes; some patients may have certain bends or curvatures in their limbs due to their own body structure characteristics;

[0004] Due to the structural characteristics of the parallel arrangement, the existing fixation plates cannot be flexibly adjusted and adapted according to the specific shapes of the limbs of different patients. This makes it difficult to achieve an ideal fixation effect because the fixation plates cannot fit well with the patient's limbs during use. On the one hand, a fixation plate that cannot fit tightly may lead to loose fixation and affect the stable recovery of the fracture site. In the patient's daily activities, the splint is prone to loosening and displacement, increasing the risk of reinjury to the fracture site. On the other hand, inappropriate fixation may also cause discomfort to the patient and even cause local compression, affecting blood circulation and delaying the recovery process. In summary, the existing orthopedic splint installation and fastening equipment has poor positioning and adaptation performance due to the structural limitations of the fixation plate, and cannot meet the complex and diverse limb needs of different patients. It has certain defects and shortcomings as a whole and is in urgent need of improvement and innovation. Summary of the invention

[0046] like Figures 1 to 9 As shown, an embodiment of the present invention provides an orthopedic splint installation and fastening device for orthopedics, including a base 1, a guide rail 2 is fixedly installed on the inner side of the base 1, a bidirectional screw rod 3 is rotatably connected inside the guide rail 2, a first motor 4 is fixedly connected to one end of the guide rail 2, an output end of the first motor 4 passes through the guide rail 2 and one end of the bidirectional screw rod 3 and is fixedly connected, the two ends of the bidirectional screw rod 3 have opposite thread rotation directions, both ends of the bidirectional screw rod 3 are threadedly connected with movable blocks 5, the movable blocks 5 are slidably connected to the inner ends of the guide rail 2, a positioning device 6 is fixedly connected to the top of the movable block 5, and mounting holes 7 are opened on both sides of the base 1, and the mounting holes 7 are set as countersunk holes.

[0047] The positioning device 6 includes a height adjustment mechanism 61, which is fixedly connected to the top of the movable block 5. The top of the height adjustment mechanism 61 is fixedly connected to a circular movement mechanism 62. Telescopic mechanisms 63 are installed at equal intervals on the inner side of the circular movement mechanism 62. The inner side of the telescopic mechanism 63 is fixedly connected to a clamping mechanism 64.

[0048] The bidirectional screw rod 3 in the guide rail 2 is driven by the first motor 4, and the threads at both ends thereof rotate in opposite directions, ensuring that the movable blocks 5 at both ends can realize precise reverse sliding at the two ends inside the guide rail 2. The movable blocks 5 are slidably connected to the two ends inside the guide rail 2, ensuring the smoothness and stability of the sliding. The positioning device 6 on the top of the movable block 5 plays a key role, wherein the height adjustment mechanism 61 is fixed on the top of the movable block 5, and can flexibly adjust the height according to different needs to adapt to the limb positions and body shapes of different patients. The circular movement mechanism 62 on the top of the height adjustment mechanism 61 can realize multi-angle rotation adjustment of the telescopic mechanism 63 and the inner splint mechanism 64 thereof, so that the equipment can better adapt to the limb parts of different patients, and can find a suitable fixed angle no matter how complex the limb shape is. The telescopic mechanism 63 installed at equal intervals on the inner side of the circular movement mechanism 62 can accurately control the position of the splint mechanism 64 to ensure that the clamping force on the patient's limb is moderate and stable.

[0049] The splint mechanism 64 on the inner side of the telescopic mechanism 63 can directly contact the patient's limbs to perform effective clamping and correction treatment. The mounting holes 7 on both sides of the base 1 are set as countersunk holes, which on the one hand make the installation more secure and enhance the stability of the equipment during use; on the other hand, it makes the surface of the equipment smoother and reduces the risk of collision caused by protruding parts.

[0050] like Figures 1 to 6As shown, the height adjustment mechanism 61 includes a sleeve tube 611, which is fixedly connected to the top of the movable block 5, and a sliding rod 612 is slidably connected inside the sleeve tube 611.

The front side of the sliding rod 612 is linearly arranged at equal intervals to provide limiting holes 614, and the end of the first screw rod 613 is inserted into the inner side of the limiting hole 614. The overall cross-sectional shape of the sliding rod 612 is set to a regular hexagon, and the overall cross-sectional shape of the internal cavity of the sleeve tube 611 is also set to a regular hexagon. The side shape of the movable block 5 and the cross-sectional shape of the internal cavity of the guide rail 2 are both set to a convex shape. The sleeve tube 611 is fixed to the top of the movable block 5, providing a stable support and sliding track for the sliding rod 612. 2 slides inside the sleeve 611, so that the circular movement mechanism 62 connected to the top of the slide bar 612 can achieve height adjustment. The first screw 613 threadedly connected to the upper end of the front side of the sleeve 611 can be inserted into the limiting holes 614 arranged linearly at equal intervals on the front side of the slide bar 612, so that the slide bar 612 can be fixed after adjusting to a suitable height, ensuring the stability of the equipment during use. The overall cross-sectional shape of the internal cavity of the slide bar 612 and the sleeve 611 is set to a regular hexagon. This shape design prevents the slide bar 612 from rotating during the sliding process, ensuring the accuracy and stability of the height adjustment. The side shape of the movable block 5 and the cross-sectional shape of the internal cavity of the guide rail 2 are both set to a convex shape, so that the movable block 5 is more stable when sliding inside the guide rail 2, and will not shake or detach from the guide rail 2, providing a reliable guarantee for the normal operation of the entire equipment.

[0051] like Figures 6 to 9As shown, the circular movement mechanism 62 includes a circular rail 621 and a limit assembly 622. The circular rail 621 is fixedly connected to the top of the slide rod 612. A plurality of sliding blocks 623 are slidably connected inside the circular rail 621. The sliding blocks 623 are arranged as a whole in an arc shape that is concentric with the circular rail 621. The inner side of the sliding blocks 623 is connected to the telescopic mechanism 63.

The block 623 is in the shape of an arc that is concentric with the annular rail 621 as a whole, and can slide smoothly inside the annular rail 621. This design makes the movement trajectory of the sliding block 623 perfectly match the shape of the annular rail 621, ensuring the stability of the movement. The inner side of the sliding block 623 is connected to the telescopic mechanism 63, realizing flexible adjustment of the position of the telescopic mechanism 63. The rail frame 6221 in the limiting component 622 is fixedly connected to the outer side of the telescopic mechanism 63 near the inner end of the annular rail 621, providing an installation position for the internal telescopic spring 6223. The telescopic spring 6223 is connected to the base block 6224, and the limiting plate 622 on the top of the base block 6224 is fixedly connected to the outer side of the telescopic mechanism 63. 5 and the limiting rod 6226 cooperate with the positioning hole 6222 on the annular rail 621, so as to fix the sliding block 623 after adjusting the position. The positioning holes 6222 arranged in an annular shape with equal intervals provide a plurality of fixing position options for the limiting rod 6226, so that the adjustment is more precise. The lower end of the adjusting plate 6227 at the bottom of the base block 6224 is arranged in an arc shape as a whole, which is convenient for operation. The outer end of the limiting plate 6225 is also arranged in an arc shape, which reduces the friction with other components and improves the smoothness of operation. This circular movement mechanism 62 can realize multi-angle adjustment of the telescopic mechanism 63 and the splint mechanism 64 to adapt to the complex shapes of different patients' limbs.

[0052] like Figures 5 to 8As shown, the telescopic mechanism 63 includes a vertical rail 631, the vertical rail 631 is fixedly connected to a side of the sliding block 623 away from the base block 6224, the rail frame 6221 is fixedly connected to the lower end of the outer side of the vertical rail 631, the outer end of the vertical rail 631 is fixedly connected to the second motor 632, the output end of the second motor 632 passes through the vertical rail 631 and is fixedly connected to a one-way screw rod 633, the one-way screw rod 633 is rotatably connected to the inside of the vertical rail 631, the outer surface of the one-way screw rod 633 is threadedly connected to a movable rod 634, the outer end of the movable rod 634 passes through the vertical rail 631 and is fixedly connected to the inner side of the clamping plate mechanism 64, the clamping plate mechanism 64 includes a mounting rail 641, the mounting rail 641 is fixedly connected to the inner side of the movable rod 634 The second screw 642 is threadedly connected to both sides of the mounting rail 641, and the end of the second screw 642 passes through the mounting rail 641. The mounting plate 643 is slidably connected to the inside of the mounting rail 641. The inner side of the mounting plate 643 is fixedly connected to the clamping arc plate 644. The overall cross-sectional shape of the mounting rail 641 and the mounting plate 643 is set to a convex shape. The cross-sectional shape of the movable rod 634 and the cross-sectional shape of the internal cavity of the mounting rail 641 are also set to a convex shape.

The rail frame 6221 is fixed on the lower end of the outer side of the vertical rail 631 to enhance the stability of the overall structure. The second motor 632 at the outer end of the vertical rail 631 drives the one-way screw rod 633 to rotate inside the vertical rail 631, so that the movable rod 634 threadedly connected to the outer surface of the one-way screw rod 633 can accurately slide inside the vertical rail 631, thereby realizing the telescopic adjustment of the splint mechanism 64 to adapt to the size and shape of different patients' limbs.

[0053] The specific working process of the technical solution provided by the present invention is as follows:

[0054] During use, the present invention can fully meet the specific needs of different patients. In actual use, first, the adjustment plate 6227 can be pulled out. This action will drive the limit plate 6225 at the end of the telescopic spring 6223 to move outward. As the limit plate 6225 moves outward, the limit rod 6226 connected to the limit plate 6225 will be pulled out from the positioning hole 6222. At this time, the limit rod 6226 and the positioning hole 6222 are separated from each other. This state allows the sliding block 623 inside the annular rail 621 to slide freely in the annular rail 621. By adjusting the sliding of the sliding block 623 in the annular rail 621, it can assist in flexibly adjusting the telescopic mechanism 63 and the splint mechanism 64 at the inner end to rotate around the patient's limbs. This rotational displacement adjustment method allows the present invention to flexibly adapt to different patient limb parts. The four telescopic mechanisms 63 and The splint mechanism 64 can be adjusted in all directions around the patient's limbs, so as to adapt to the complex and diverse limb conditions of different patients to the greatest extent. When the adjustment is completed, the adjustment plate 6227 is released. At this time, the telescopic spring 6223 will quickly reset, driving the base block 6224 inside the rail frame 6221 to slide inward. The sliding of the base block 6224 will further drive the limiting rod 6226 at the end of the limiting plate 6225 to be reinserted into the inner side of the positioning hole 6222 at the corresponding position. The limiting rod 6226 on the limiting plate 6225 and the positioning hole 6222 are plugged into each other, so that the sliding block 623 inside the annular rail 621 can be firmly fixed. In this way, the device can achieve flexible and rapid displacement adjustment while also having excellent stability, ensuring that there will be no accidental loosening or displacement during use, thereby providing reliable protection for the patient's fracture fixation treatment.

[0055] The device is provided with a guide rail 2 and a bidirectional screw rod 3 inside thereof, so that it can be accurately adjusted according to the patient's limb length during use. Specifically, during the adjustment process, the first motor 4 can be started to run, and the first motor 4 will drive the bidirectional screw rod 3 inside the guide rail 2 to rotate. When the bidirectional screw rod 3 rotates inside the guide rail 2, it can drive the movable blocks 5 at both ends of the guide rail 2 to slide. The movable blocks 5 are driven to slide by the bidirectional screw rod 3, and the movable blocks 5 can perform reciprocating sliding displacement at both ends of the guide rail 2. At this time, by adjusting the reciprocating sliding displacement of the movable block 5, the two sets of splint mechanisms 64 can be synchronously driven to perform reciprocating lateral displacement. The displacement of the splint mechanism 64 can adjust the distance between the two splint mechanisms 64, so that the device can be used during use. It can flexibly adapt to the limb lengths of different patients. In addition, during the adjustment process, the height adjustment can be achieved by sliding the sliding rod 612 inside the sleeve tube 611. The height of the splint mechanism 64 can be flexibly adjusted by sliding the sliding rod 612 up and down. By adjusting the height of the splint mechanism 64, further fine adjustments can be made according to the patient's limb needs. In the adjustment process, the first screw 613 can be twisted to displace it and insert it into the inner side of the limiting hole 614. At this time, the first screw 613 can assist in fixing the sleeve tube 611 and the sliding rod 612 to ensure the stability of the device after adjustment. The overall height adjustment and spacing adjustment characteristics of the device can further adapt to the limb lengths of different patients and provide patients with more personalized treatment plans.

[0056] When the splint mechanism 64 of the device is adjusted, the second motor 632 can be started to operate. The operation of the second motor 632 will drive the one-way screw rod 633 located inside the vertical rail 631 to rotate. After the one-way screw rod 633 rotates, it will drive the movable rod 634 to slide inside the vertical rail 631. By adjusting the sliding of the movable rod 634 inside the vertical rail 631, the movable rod 634 can push the splint mechanism 64 to move toward the patient's limb. At this time, the clamping arc plate 644 on the inner side of the mounting rail 641 moves inward to assist in fitting to the outer surface of the patient's limb, thereby clamping and correcting the patient's limb. During the adjustment process, the clamping arc plate 644 can be set to multiple models according to specific needs. For example, different models can be set according to the patient's weight, age and gender. When the patient is smaller, a smaller clamping arc plate can be selected. Arc plate 644, at this time loosen the second screw 642 to make its end disengage from the clamping hole 645, then the mounting plate 643 inside the mounting rail 641 can be pulled out, when the mounting plate 643 is pulled out, the clamping arc plate 644 can be removed from the inside of the telescopic mechanism 63, then, the mounting plate 643 with the smaller clamping arc plate 644 is inserted into the inside of the mounting rail 641, and the clamping arc plate 644 can be installed and positioned by twisting the second screw 642 and inserting it into the inner side of the clamping hole 645. It can be seen that the device can not only be flexibly adjusted and adapted, but also can be further disassembled and replaced according to the needs of the patient. This feature allows the device to better adapt to different patients, can further improve the overall use adaptation performance of the device, and provide patients with more comfortable and effective fracture fixation treatment.
