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

[0005] In view of the problem in the prior art that the prior art cannot flexibly adapt to clamp different patients during application, an object of the present invention is to provide an orthopedic splint installation and fastening device for orthopedics.

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

[0007] An orthopedic splint installation and fastening device for orthopedics, including a base. A guide rail is fixedly installed inside the base.

A sliding rod is slidably connected inside the sleeve pipe. The top of the sliding rod is connected to the bottom of the ring movement mechanism. The upper end of the front surface of the sleeve pipe is threadedly connected with a first screw rod. The end of the first screw rod penetrates through the sleeve pipe.

[0010] Optionally, limiting holes are linearly arranged at equal intervals on the front surface of the sliding rod. The end of the first screw rod is inserted inside the limiting holes.

[0011] Optionally, the overall cross-sectional shape of the sliding rod is set to a regular hexagon. The overall cross-sectional shape of the inner cavity of the sleeve pipe is also set to a regular hexagon. The side shape of the movable block and the cross-sectional shape of the inner cavity of the guide rail are both set to a convex shape.

[0012] Optionally, the ring movement mechanism includes an annular rail and a limiting component. The annular rail is fixedly connected to the top of the sliding rod. A plurality of sliding blocks are slidably connected inside the annular rail. The sliding blocks are integrally set to be in an arc shape concentric with the annular rail. The inner side of the sliding blocks is connected to the telescopic mechanisms. The limiting component is fixedly connected to one end of the telescopic mechanism close to the inner side of the annular rail.

[0013] Optionally, the limiting component includes a rail frame and positioning holes. The rail frame is fixedly connected to the outside of one end of the telescopic mechanism close to the inner side of the annular rail. A telescopic spring is fixedly connected inside the rail frame. The outer end of the telescopic spring is fixedly connected to a base block. A limiting plate is fixedly connected to the top of the base block. A limiting rod is fixedly connected to one side of the upper end of the limiting plate close to the annular rail. The positioning holes are arranged in an annular pattern at equal intervals on the side of the annular rail away from the telescopic mechanism. The end of the limiting rod is inserted inside the limiting holes.

[0014] Optionally, the bottom of the base block is fixedly connected with an adjusting plate, the lower end of the adjusting plate is integrally arranged in an arc shape, and the outer end of the limiting plate is also arranged in an arc shape.

[0015] Optionally, the telescopic mechanism includes a vertical rail fixedly connected to a side of the sliding block away from the base block, a rail frame fixedly connected to the lower end of the outer side of the vertical rail, a second motor fixedly connected to the outer end of the vertical rail, an output end of the second motor penetrating through the vertical rail and fixedly connected with a unidirectional screw rod, the unidirectional screw rod rotatably connected to the inside of the vertical rail, an outer surface of the unidirectional screw rod threadedly connected with a movable rod, and an outer end of the movable rod penetrating through the vertical rail and fixedly connected to the inner side of the clamping plate mechanism.

[0016] Optionally, the clamping plate mechanism includes a mounting rail fixedly connected to the inner end of the movable rod, second screw rods threadedly connected to both sides of the mounting rail, ends of the second screw rods penetrating through the mounting rail, a mounting plate slidably connected to the inside of the mounting rail, and a clamping arc plate fixedly connected to the inner side of the mounting plate.

[0017] Optionally, the overall cross-sectional shapes of the mounting rail and the mounting plate are both arranged in a convex shape, the cross-sectional shape of the movable rod and the cross-sectional shape of the inner cavity of the mounting rail are also both arranged in a convex shape, the first screw rod and the second screw rod are both hand-tightening screw rods, clamping holes are formed at both ends of the mounting plate, and the ends of the second screw rods are inserted into the clamping holes.

[0018] The technical solution provided by the present invention has at least the following beneficial effects compared with the prior art:

[0019] In the above solution, by setting the annular movement mechanism, the specific needs of different patients can be fully met during use. During operation, pulling the adjusting plate can drive the limiting plate at the end of the telescopic spring to move outward, so that the limiting rod is pulled out of the positioning hole. At this time, the sliding block in the annular rail can slide freely, and then drive the telescopic mechanism and the clamping plate mechanism to rotate around the patient's limb. The four telescopic mechanisms and the clamping plate mechanism can be adjusted in all directions to adapt to the complex limb conditions of different patients. After the adjustment is completed, releasing the adjusting plate, the telescopic spring resets, driving the limiting rod to be inserted into the positioning hole again to fix the sliding block. In this way, both flexible and rapid displacement adjustment is realized, and excellent stability is also achieved, providing a reliable guarantee for the fracture fixation treatment of patients and ensuring that no accidental loosening or displacement will occur during use;

[0020] By setting the guide rail and the bidirectional lead screw inside it, precise adjustment can be made according to the length of the patient's limb during use. Start the first motor to drive the bidirectional lead screw to rotate inside the guide rail, so that the movable blocks at both ends of the guide rail slide. The reciprocating sliding displacement of the movable blocks can synchronously drive the two sets of splint mechanisms to move horizontally, adjust the distance between the two splint mechanisms, and adapt to the limb lengths of different patients. In addition, the sliding of the slide bar inside the sleeve can be adjusted to achieve height adjustment, and further fine-tuning can be carried out according to the needs of the patient's limb. During the adjustment process, twist the first screw and insert it into the limit hole to assist in fixing the sleeve and the slide bar to ensure the stability of the device. The characteristics of adjustable overall height and spacing provide a more personalized treatment plan for patients;

[0021] Through the cooperation of the telescopic mechanism and the splint mechanism, during use, after the splint mechanism is adjusted, start the second motor to drive the unidirectional lead screw to rotate in the vertical rail, so that the movable rod slides and pushes the splint mechanism to move towards the patient's limb. The clamping arc plate on the inner side of the installation rail fits the outer surface of the patient's limb for clamping and correction treatment. Multiple models of the clamping arc plate can be set according to the patient's weight, age, and gender. When the patient is of a small body type, the second screw can be loosened to extract the installation plate, and after replacing the installation plate with a smaller clamping arc plate, it can be fixed again. This device can not only be flexibly adjusted and adapted, but also disassembled and replaced the clamping arc plate according to needs, better adapting to different patients and improving the overall use adaptability performance, providing a more comfortable and effective fracture fixation treatment for patients.

[0046] As Figures 1 to 9 shown, an orthopedic splint installation and fastening device for orthopedics provided by an embodiment of the present invention includes a base 1. A guide rail 2 is fixedly installed inside the base 1. A bidirectional lead screw 3 is rotatably connected inside the guide rail 2. One end of the guide rail 2 is fixedly connected to a first motor 4. The output end of the first motor 4 penetrates through the guide rail 2 and is fixedly connected to one end of the bidirectional lead screw 3. The thread directions at both ends of the bidirectional lead screw 3 are opposite. Both ends of the bidirectional lead screw 3 are threadedly connected to movable blocks 5. The movable blocks 5 are slidably connected to both ends inside the guide rail 2. A positioning device 6 is fixedly connected to the top of the movable blocks 5. Mounting holes 7 are formed on both sides of the base 1. The mounting holes 7 are countersunk holes.

[0047] The positioning device 6 includes a height adjustment mechanism 61, the height adjustment mechanism 61 is fixedly connected to the top of the movable block 5, the top of the height adjustment mechanism 61 is fixedly connected with a circumferential movement mechanism 62, a telescopic mechanism 63 is equidistantly installed inside the circumferential movement mechanism 62, and a clamping plate mechanism 64 is fixedly connected to the inside of the telescopic mechanism 63.

[0048] The bidirectional lead screw 3 in the guide rail 2 is driven by the first motor 4, and the thread directions at both ends are opposite, ensuring that the movable blocks 5 at both ends can achieve precise reverse sliding at both ends inside the guide rail 2. The movable blocks 5 are slidably connected to both 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. Among them, 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 shape differences of different patients. The circumferential 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 clamping plate mechanism 64 inside it, enabling the device to better adapt to the limb parts of different patients and find a suitable fixing angle regardless of how complex the limb shape is. The telescopic mechanisms 63 equidistantly installed inside the circumferential movement mechanism 62 can precisely control the position of the clamping plate mechanism 64 to ensure that the clamping force on the patient's limb is moderate and stable.

[0049] The clamping plate mechanism 64 inside the telescopic mechanism 63 can directly contact the patient's limb for effective clamping and correction treatment. The mounting holes 7 on both sides of the base 1 are countersunk holes, on the one hand, making the installation more firm and enhancing the stability of the device during use; on the other hand, making the surface of the device smoother and reducing the collision risk caused by protruding components.

[0050] Such as Figures 1 to 6As shown, the height adjustment mechanism 61 includes a sleeve pipe 611. The sleeve pipe 611 is fixedly connected to the top of the movable block 5. A slide bar 612 is slidably connected inside the sleeve pipe 611. The top of the slide bar 612 is connected to the bottom of the annular movement mechanism 62. The upper end of the front surface of the sleeve pipe 611 is threadedly connected with a first screw rod 613. The end of the first screw rod 613 penetrates through the sleeve pipe 611. The front surface of the slide bar 612 is provided with a plurality of equally spaced and linearly arranged limit holes 614 at equal intervals. The end of the first screw rod 613 is inserted into the inner side of the limit hole 614. The overall cross-sectional shape of the slide bar 612 is set to a regular hexagon, and the overall cross-sectional shape of the inner cavity of the sleeve pipe 611 is also set to a regular hexagon. The side shape of the movable block 5 and the cross-sectional shape of the inner cavity of the guide rail 2 are both set to a convex shape. The sleeve pipe 611 is fixed on the top of the movable block 5, providing a stable support and sliding track for the slide bar 612. The slide bar 612 slides inside the sleeve pipe 611, enabling the annular movement mechanism 62 connected to the top of the slide bar 612 to achieve height adjustment. The first screw rod 613 threadedly connected to the upper end of the front surface of the sleeve pipe 611, its end can be inserted into the limit holes 614 linearly arranged at equal intervals on the front surface of the slide bar 612, and can fix the slide bar 612 after adjusting to the appropriate height, ensuring the stability of the equipment during use. The overall cross-sectional shape of the inner cavities of the slide bar 612 and the sleeve pipe 611 are both set to a regular hexagon. This shape design enables the slide bar 612 not to rotate 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 inner cavity of the guide rail 2 are both set to a convex shape, making the movable block 5 slide more stably inside the guide rail 2 and not shake or disengage from the guide rail 2, providing a reliable guarantee for the normal operation of the entire equipment.

[0051] As Figures 6 to 9As shown, the ring moving mechanism 62 includes an annular rail 621 and a limiting component 622. The annular rail 621 is fixedly connected to the top of the sliding rod 612. A plurality of sliding blocks 623 are slidably connected inside the annular rail 621. The sliding blocks 623 are integrally arranged in an arc shape concentric with the annular rail 621. The inner side of the sliding block 623 is connected to the telescopic mechanism 63. The limiting component 622 is fixedly connected to one end of the telescopic mechanism 63 close to the inner side of the annular rail 621. The limiting component 622 includes a rail frame 6221 and a positioning hole 6222. The rail frame 6221 is fixedly connected to the outer side of one end of the telescopic mechanism 63 close to the inner side of the annular rail 621. A telescopic spring 6223 is fixedly connected inside the rail frame 6221. The outer end of the telescopic spring 6223 is fixedly connected to a base block 6224. The top of the base block 6224 is fixedly connected to a limiting plate 6225. One side of the upper end of the limiting plate 6225 close to the annular rail 621 is fixedly connected to a limiting rod 6226. The positioning holes 6222 are arranged in an equidistant annular pattern on the side of the annular rail 621 away from the telescopic mechanism 63. The end of the limiting rod 6226 is inserted into the inner side of the limiting hole 614. The bottom of the base block 6224 is fixedly connected to an adjusting plate 6227. The lower end of the adjusting plate 6227 is integrally arranged in an arc shape. The outer end of the limiting plate 6225 is also arranged in an arc shape. The sliding blocks 623 are integrally in an arc shape concentric with the annular rail 621 and can slide smoothly inside the annular rail 621. And this design makes the movement track of the sliding blocks 623 perfectly fit the shape of the annular rail 621, ensuring the stability of the movement. The inner side of the sliding blocks 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 one end of the telescopic mechanism 63 close to the inner side 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. The limiting plate 6225 and the limiting rod 6226 on the top of the base block 6224 cooperate with the positioning holes 6222 on the annular rail 621, and can fix the sliding blocks 623 after adjusting the position. The positioning holes 6222 arranged in an equidistant annular pattern provide multiple fixed position choices for the limiting rod 6226, making the adjustment more precise. The lower end of the adjusting plate 6227 at the bottom of the base block 6224 is integrally arranged in an arc shape, which is convenient for operation. The outer end of the limiting plate 6225 is also arranged in an arc shape, reducing the friction with other components and improving the smoothness of the operation. This ring moving mechanism 62 can realize multi-angle adjustment of the telescopic mechanism 63 and the clamping plate mechanism 64 to adapt to the complex shapes of different patients' limbs.

[0052] As Figures 5 to 8As shown in the figure, the telescopic mechanism 63 includes a vertical rail 631, which is fixedly connected to the 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. A second motor 632 is fixedly connected to the outer end of the vertical rail 631. The output end of the second motor 632 penetrates through the vertical rail 631 and is fixedly connected with a unidirectional lead screw 633. The unidirectional lead screw 633 is rotatably connected to the inside of the vertical rail 631. An actuating rod 634 is threadedly connected to the outer surface of the unidirectional lead screw 633. The outer end of the actuating rod 634 penetrates 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, which is fixedly connected to the inner end of the actuating rod 634. Second screws 642 are threadedly connected to both sides of the mounting rail 641. The ends of the second screws 642 penetrate through the mounting rail 641. A mounting plate 643 is slidably connected to the inside of the mounting rail 641. A clamping arc plate 644 is fixedly connected to the inner side of the mounting plate 643. The overall cross-sectional shapes of the mounting rail 641 and the mounting plate 643 are both set to convex shapes. The cross-sectional shape of the actuating rod 634 and the cross-sectional shape of the inner cavity of the mounting rail 641 are also both set to convex shapes. The first screw 613 and the second screw 642 are both set to hand-tightening screws. Card holes 645 are opened at both ends of the mounting plate 643. The ends of the second screws 642 are inserted into the card holes 645. The vertical rail 631 in the telescopic mechanism 63 is fixed on the sliding block 623, providing a stable support structure for the unidirectional lead screw 633 and the actuating rod 634. The rail frame 6221 is fixed to the lower end of the outer side of the vertical rail 631, enhancing the stability of the overall structure. The second motor 632 at the outer end of the vertical rail 631 drives the unidirectional lead screw 633 to rotate inside the vertical rail 631, enabling the actuating rod 634 threadedly connected to the outer surface of the unidirectional lead screw 633 to slide precisely inside the vertical rail 631, thereby realizing the telescopic adjustment of the clamping plate mechanism 64 to adapt to the sizes and shapes of different patients' limbs. The mounting rail 641 in the clamping plate mechanism 64 is fixed to the inner end of the actuating rod 634. The second screws 642 threadedly connected to both sides thereof can fix the mounting plate 643 installed inside. The overall cross-sectional shapes of the mounting rail 641 and the mounting plate 643 and the cross-sectional shape of the actuating rod 634 are all set to convex shapes, ensuring the stability of the mounting plate 643 sliding inside the mounting rail 641 and the connection between the actuating rod 634 and the mounting rail 641, preventing shaking or detachment during use. The clamping arc plate 644 on the inner side of the mounting plate 643 can directly contact the patient's limb and clamp and correct it. The first screw 613 and the second screw 642 are both set to hand-tightening screws, which is convenient for operation and improves the convenience of equipment use. The card holes 645 opened at both ends of the mounting plate 643 cooperate with the second screws 642, making the fixation of the mounting plate 643 more firm and reliable.

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

[0054] During the use of this device, it can fully meet the specific needs of different patients. In the actual use process, first, the pull-adjusting plate 6227 can be pulled. This action will drive the limit plate 6225 at the end of the telescopic spring 6223 to move outwards. As the limit plate 6225 moves outwards, 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 enables the sliding block 623 inside the annular track 621 to slide freely in the annular track 621. By adjusting the sliding of the sliding block 623 in the annular track 621, it can assist in flexibly adjusting the telescopic mechanism 63 and the clamping plate mechanism 64 at its inner end to rotate around the patient's limb. This adjustment method of rotational displacement enables this device to flexibly adapt to the limb parts of different patients. The four telescopic mechanisms 63 and the clamping plate mechanism 64 can perform all-round adjustment around the patient's limb, so as to best adapt to the complex and diverse limb conditions of different patients. When the adjustment is completed, the adjusting 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 towards the inside. The sliding of the base block 6224 will further drive the limit rod 6226 at the end of the limit plate 6225 to re-insert into the inner side of the positioning hole 6222 at the corresponding position. By the mutual insertion and clamping of the limit rod 6226 on the limit plate 6225 and the positioning hole 6222, the sliding block 623 inside the annular track 621 can be firmly fixed. In this way, while this device realizes flexible and rapid displacement adjustment, it also has excellent stability, ensuring that there will be no accidental loosening or displacement during use, providing a reliable guarantee for the fracture fixation treatment of patients.

[0055] By setting the guide rail 2 and the bidirectional lead screw 3 inside it, this device can be precisely adjusted according to the limb length of the patient during use. Specifically, during the adjustment process, the first motor 4 can be started to operate. After the first motor 4 operates, it will drive the bidirectional lead screw 3 inside the guide rail 2 to rotate. When the bidirectional lead screw 3 rotates inside the guide rail 2, it can drive the movable blocks 5 at both ends inside the guide rail 2 to slide. By driving the movable blocks 5 to slide with the bidirectional lead screw 3, the movable blocks 5 can reciprocally slide and displace at both ends inside the guide rail 2. At this time, by adjusting the reciprocal sliding displacement of the movable blocks 5, two sets of splint mechanisms 64 can be synchronously driven to reciprocally displace horizontally. The displacement of the splint mechanisms 64 can adjust the distance between the two splint mechanisms 64, enabling this device to flexibly adapt to the limb lengths of different patients during use. In addition, during the adjustment process, the height can be adjusted by sliding the sliding rod 612 inside the sleeve pipe 611. By sliding the sliding rod 612 up and down, the height of the splint mechanism 64 can be flexibly adjusted. By adjusting the height of the splint mechanism 64, further fine adjustment can be made according to the limb requirements of the patient. And during the adjustment process, the first screw 613 can be twisted to make it displace and insert into the inner side of the limit hole 614. At this time, the first screw 613 can assist in fixing the sleeve pipe 611 and the sliding rod 612, ensuring the stability of the device after adjustment. The characteristics of the overall height adjustment and spacing adjustment of this device can further adapt to the limb lengths of different patients and provide a more personalized treatment plan for the patients.

[0056] After the clamping plate mechanism 64 of the present device is adjusted, the second motor 632 can be started to operate. The operation of the second motor 632 will drive the unidirectional lead screw 633 to rotate inside the vertical rail 631. After the unidirectional lead screw 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, it can prompt the movable rod 634 to push the clamping plate mechanism 64 towards the patient's limb. At this time, the clamping arc plate 644 inside the mounting rail 641 moves inward to assist in fitting to the outer surface of the patient's limb, and then the patient's limb can be clamped and corrected. During the adjustment process, the clamping arc plate 644 can be set into multiple models according to specific requirements. For example, it can be set into different models according to the patient's weight, age, and gender. When the patient is of a smaller build, a smaller clamping arc plate 644 can be selected. At this time, loosen the second screw 642 so that its end disengages from the card hole 645. Then, the mounting plate 643 inside the mounting rail 641 can be pulled out. After the mounting plate 643 is pulled out, the clamping arc plate 644 can be removed from the inside of the telescopic mechanism 63. Then, insert the mounting plate 643 with the smaller clamping arc plate 644 into the mounting rail 641. By twisting the second screw 642 and inserting it into the inside of the card hole 645, the clamping arc plate 644 can be installed and positioned. It can be seen that the present device can not only be flexibly adjusted and adapted, but also can be further disassembled and assembled to replace the clamping arc plate 644 according to the patient's needs. This characteristic enables the present device to better adapt to different patients and can further improve the overall use adaptability of the present device, providing more comfortable and effective fracture fixation treatment for patients.
