Description

Technical Field

[0001] This invention belongs to the technical field of osteotomy fixation plates, specifically relating to a quick-tightening suture-type bone fixation plate. Background Technology

[0002] Osteotomy is a surgical procedure in which bones are shortened, lengthened, and / or rearranged. Specifically, ulnar shortening osteotomy removes the ulna to treat symptoms such as wrist pain, swelling, limited range of motion, and decreased grip strength, which may be caused by conditions such as ulnar compression syndrome. Ulnar compression syndrome is a degenerative condition associated with excessive load on the lateral aspect of the ulna and chronic impact of the ulnar head on the TFCC, lunate, and triquetrum. By shortening the ulna, compression is reduced, preventing wrist pain, swelling, and other symptoms, thus restoring wrist joint function.

[0003] The patent announcement number “CN102791211B” discloses a bone plate (100) comprising: a first three-part combination hole (110) extending through a proximal portion of the bone plate; a first portion (112) for engaging a threaded head portion of a bone fixation element (122); a second portion (114) for receiving a bone fixation element (126) along an axis substantially perpendicular to the longitudinal axis of the bone; and a third portion (116) defining a screw axis extending at a non-perpendicular angle toward the distal end of an elongated body relative to the longitudinal axis; and incorporating a first two-part combination hole (138) extending through the proximal portion, a first threaded portion (140) for engaging the threaded head portion of the bone fixation element (122), and a second portion (142) defining an elongated groove extending along the longitudinal axis of the plate for receiving the bone fixation element such that the bone plate can slide relative to the bone fixation element along its longitudinal axis.

[0004] The aforementioned patent addresses the issue of bone plates sliding relative to bone fixation elements along their longitudinal axis by receiving bone fixation elements. However, in existing technologies, for fracture patients, holes need to be drilled to fix larger bones such as those in the shoulder, knee, hip, and elbow, and most fixation plates are only used on one side of the bone, resulting in uneven stress and angled bones after recovery. If the bone is fixed on both sides, more bone screws are used, and multiple drillings reduce the bone's load-bearing capacity. For smaller bones in the hands and feet, fixation plates need to be implanted inside the bone, which involves complex surgical procedures and high risks. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-tightening suture-type bone fixation plate, which aims to solve the problems in existing technologies for fracture patients. For larger bones such as the shoulder, knee, hip, and elbow, holes need to be drilled to fix the fixation plate. Most fixation plates are only used on one side of the bone, resulting in uneven stress and angled bones after recovery. If the bone is fixed on both sides, more bone screws are used, and multiple drillings reduce the stress-bearing capacity of the bone. For smaller bones such as the hands and feet, fixation plates need to be implanted inside the bone, which involves complex surgical procedures and high risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-tightening suture fixation plate, comprising:

[0008] Two fixing plates;

[0009] Multiple first circular holes are respectively opened on the circumferential surface of the two fixing plates;

[0010] Two sutures, the two sutures being located within a plurality of first circular holes;

[0011] Two sets of movable adjustment mechanisms, each set including a placement groove, a slider, a first support plate, a long block, a pad, a support rod, and a second circular hole. The placement groove is opened on the inner circumference of the fixed plate, the first support plate is located in the placement groove, the slider is slidably connected in the placement groove, the long block is fixedly connected to the upper end of the first support plate, the second circular hole is opened at the upper end of the slider, the pad is located at the upper end of the slider, the support rod is fixedly connected to the lower end of the pad, and the support rod is located in the second circular hole.

[0012] Two sets of locking mechanisms are respectively located at both ends of the long block to lock the long block.

[0013] As a preferred embodiment of the present invention, each locking mechanism includes a second insertion hole, a support plate, a pin, a first insertion hole, and a second support plate. The support plate is fixedly connected to one side of the long block. The first insertion hole is opened at the upper end of the support plate. The second support plate is fixedly connected to the lower inner wall of the placement groove. The second insertion hole is opened at the upper end of the second support plate. The pin is located inside the first insertion hole and the second insertion hole.

[0014] As a preferred embodiment of the present invention, each of the plurality of first circular holes is provided with a limiting ring on its inner circumference, and the length of the limiting ring is half of the length of the first circular hole.

[0015] As a preferred embodiment of the present invention, protective plates are fixedly connected to both ends of the two fixing plates, and the protective plates are made of rubber.

[0016] As a preferred embodiment of the present invention, anti-slip pads are fixedly connected to the circumferential surfaces of both fixing plates.

[0017] As a preferred embodiment of the present invention, two grooves are formed on the circumferential surfaces of the two fixing plates, and the length of the grooves is 0.5cm.

[0018] As a preferred embodiment of the present invention, the radius of the first circular hole is 1.5 cm, and the radius of the suture is 1.25 cm.

[0019] As a preferred embodiment of the present invention, four blocks are fixedly connected to the inner circumference of each of the two second circular holes, and the four support rods are matched with the second circular holes.

[0020] In a preferred embodiment of the present invention, the height of the pad is 1 cm, and the material of the pad is silicone.

[0021] As a preferred embodiment of the present invention, a spring is fixedly connected to one side end of the first support plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Two fixation plates can be used together. The two fixation plates are inserted into the head of the device to fix the bone. Taking the finger joint as an example, the device is placed on the fracture site, the head of the device bites, and the raised part of the pad lifts the concave part of the bone. The surgeon only needs to tighten one end of the suture and tie a knot to fix it, release the device, and suture the wound. The two fixation plates can be used at the same time. The operation is simple and labor-saving. The fracture site is well located and wrapped in the correct position. There is no need to embed bone nails, which protects the bone's stress capacity, does not damage the bone, does not require secondary surgery, and has a short recovery period.

[0024] 2. When binding sutures at cross points, sufficient gaps can be left to help personnel quickly tighten the sutures. This provides enough space for personnel to complete the task quickly, preventing jamming when pulling the sutures to tie knots, protecting the patient's safety, and speeding up the surgical process.

[0025] 3. When the head and tail of the suture need to be crossed and bound, the suture can be placed in the groove. This will prevent the suture from shaking. After the fixing plate is bound, the protective plate will prevent the front and tail of the fixing plate from damaging the bone, thus protecting the bone and providing a cushioning effect.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figures 1-8 The present invention provides the following technical solutions:

[0039] A quick-tightening suture fixation plate, comprising:

[0040] Two fixing plates 1;

[0041] Multiple first circular holes 3 are respectively opened on the circumferential surface of the two fixing plates 1;

[0042] Two sutures 5, the two sutures 5 are located within a plurality of first circular holes 3;

[0043] Two sets of movable adjustment mechanisms, each set of movable adjustment mechanisms includes a placement groove 8, a slider 9, a first support plate 11, a long block 12, a pad 18, a support rod 19, and a second circular hole 20. The placement groove 8 is opened on the inner circumference of the fixed plate 1. The first support plate 11 is located in the placement groove 8. The slider 9 is slidably connected in the placement groove 8. The long block 12 is fixedly connected to the upper end of the first support plate 11. The second circular hole 20 is opened at the upper end of the slider 9. The pad 18 is located at the upper end of the slider 9. The support rod 19 is fixedly connected to the lower end of the pad 18 and is located in the second circular hole 20.

[0044] Two sets of locking mechanisms are respectively located at both ends of the long block 12 to lock the long block 12.

[0045] In a specific embodiment of the present invention, multiple sliders 9 are placed in the placement groove 8, allowing them to move. A long block 12, along with the first support plate 11, is installed into the placement groove 8, restricting the movement of the sliders 9 and preventing them from falling off. Sutures 5 are inserted in an X-shape through multiple first circular holes 3, allowing the two fixation plates 1 to be bound together. During surgery, the two fixation plates 1 are inserted into the head of the device to bind the bone. Taking a finger joint as an example, the device is placed at the fracture site, and the head of the device engages. Due to the different shapes of bones, there is an unevenness. A pad 18 is prepared beforehand. The support rod 19 at the bottom is inserted into the corresponding second circular hole 20. This allows the raised part of the pad 18 to support the concave part of the bone, making the device more stable. When binding is required, the surgeon only needs to tighten one end of the suture 5, tie a knot to fix it, loosen the inserter, and suture the wound. This device uses two fixation plates 1 at the same time, which is simple and labor-saving to operate. It can accurately locate the fracture site, wrap it in the correct position, and does not require the embedding of bone nails. It protects the bone's stress capacity, does not damage the bone, does not require secondary surgery, and has a short recovery period. The locking mechanism can also be used to fix the long block 12 so that it will not shake during use.

[0046] Please refer to the details. Figures 6-7 Each locking mechanism includes a second insertion hole 10, a support plate 14, a pin 15, a first insertion hole 16, and a second support plate 17. The support plate 14 is fixedly connected to one side of the long block 12. The first insertion hole 16 is opened at the upper end of the support plate 14. The second support plate 17 is fixedly connected to the lower inner wall of the placement groove 8. The second insertion hole 10 is opened at the upper end of the second support plate 17. The pin 15 is located inside the first insertion hole 16 and the second insertion hole 10.

[0047] In this embodiment: During installation, the second support plate 17 supports the support plates 14 on both sides, thus maintaining the stability of the long block 12. At the same time, the openings of the first insertion hole 16 and the second insertion hole 10 are aligned. The larger pin 15 is inserted into the first insertion hole 16 and the second insertion hole 10, so that the support plate 14 and the second support plate 17 are bound together. When bound, the long block 12 is flush with the fixing plate 1, so there is no exposed situation, which allows the fixing plate 1 to be used normally and also makes it convenient for the patient to move around later. When disassembling, the long block 12 can be quickly removed by simply removing the pin 15.

[0048] Please refer to the details. Figures 1-3 Each of the multiple first circular holes 3 has a limiting ring 4 on its inner circumference, and the length of the limiting ring 4 is half that of the first circular hole 3.

[0049] In this embodiment: the limiting ring 4 is located inside the first circular hole 3 and its length is half of the first circular hole 3. It is set on the outer part near the fixing plate 1. When the sewing thread 5 passes through the first circular hole 3, the limiting ring 4 plays a role in preventing wear. Since the limiting ring 4 is located inside the first circular hole 3, it will not interfere with the normal use of the fixing plate 1. At the same time, the short length of the first circular hole 3 will not affect the normal pulling of the first circular hole 3, making it convenient to use.

[0050] Please refer to the details. Figure 2 Both ends of the two fixed plates 1 are fixedly connected with protective plates 7, which are made of rubber.

[0051] In this embodiment: After the fixing plate 1 is bound, the protective plate 7 ensures that the front and rear ends of the fixing plate 1 will not damage the bone, protecting the bone and providing a cushioning effect. At the same time, the protective plate 7 is made of rubber, which can increase comfort. It is fixed by adhesive and easy to remove.

[0052] Please refer to the details. Figure 2 Anti-slip pads 2 are fixedly connected to the circumferential surfaces of both fixing plates 1.

[0053] In this embodiment, the anti-slip mat 2 is designed to make it easy for medical staff to pick up the sutures and prevent them from slipping. At the same time, the design of the anti-slip mat 2 will not affect the cross-winding of the sutures 5 or the normal use of the fixing plate 1.

[0054] Please refer to the details. Figure 1 Two grooves 6 are provided on the circumferential surface of the two fixing plates 1, and the length of the grooves 6 is 0.5cm.

[0055] In this embodiment: when the head and tail of the suture 5 need to be cross-bound, the suture 5 can be placed in the groove 6, which makes the suture 5 less likely to shake. The groove 6 is 0.5cm deep, which can accommodate a normal suture 5, protect the safety of the suture 5, and make it easy to pick up the suture 5.

[0056] Please refer to the details. Figure 1 The radius of the first circular hole 3 is 1.5cm, and the radius of the sewing thread 5 is 1.25cm.

[0057] In this embodiment, the diameter of the suture 5 is 2.5cm, which is 0.5cm smaller than the diameter of the first circular hole 3. When the suture 5 is crossed and bound, there is enough gap to help the personnel quickly tighten the suture 5. It has enough space to help the personnel complete the task quickly and increase the mobility.

[0058] Please refer to the details. Figure 8 Each of the two second circular holes 20 has four stops 21 fixedly connected to its inner circumference, and four support rods 19 are matched with the second circular holes 20.

[0059] In this embodiment, the circumferential surface of the support rod 19 has a groove that matches the stop block 21. When the support rod 19 is inserted into the second circular hole 20, the stop block 21 matches the groove, which can prevent rotation and stably limit the support rod 19, protect the stability of the pad 18, and prevent the pad 18 from rotating or shaking, making it convenient to load the pad 18.

[0060] Please refer to the details. Figure 8 The height of pad 18 is 1cm, and the material of pad 18 is silicone.

[0061] In this embodiment: after the pad 18 is installed, the height of the main body is 1cm higher than the device, so that it will not be particularly prominent and it is convenient to restrict the concave part of the bone. The pad 18 is made of silicone to maintain comfort and at the same time, it will not damage the bone.

[0062] Please refer to the details. Figure 5 A spring 13 is fixedly connected to one side of the first support plate 11.

[0063] In this embodiment: multiple sets of springs 13 are provided in this device. After the slider 9 is installed, it can be adjusted left and right. When the slider 9 contacts the spring 13, it can achieve a buffering effect, reduce the impact force, and keep the slider 9 stable.

[0064] The working principle and usage process of this invention are as follows: During use, the suture 5 is inserted into multiple first circular holes 3 in an X-shape. The two fixation plates 1 can be bound together. During surgery, the patient inserts the two fixation plates 1 into the head of the device to bind the bone. Taking the finger joint as an example, the device is placed on the fracture site, and the head of the device engages. Due to the different shapes of the bones, there will be concave and convex phenomena. The pad 18 is inserted into the corresponding second circular hole 20 through the support rod 19 at the bottom. In this way, the convex part of the pad 18 can be used to pad the concave part of the bone. The surgeon only needs to pull one end of the suture 5 tight and tie a knot to fix it, loosen the device, and suture the wound. The two fixation plates 1 are used at the same time, which is simple and labor-saving. The fracture site is well positioned and wrapped in the correct direction. There is no need to embed bone nails, which protects the bone's stress capacity, does not damage the bone, does not require secondary surgery, and has a short recovery period.

[0065] 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
