Description

Technical Field

[0001] The present invention relates to the technical field of medical orthopedic devices, and more specifically, to a fibula transverse bone transport external fixator device and a method for using the same. Background Art

[0002] Diabetic foot is characterized by poor local blood circulation, low immune function, and being prone to infection and spread. Therefore, the wound repair of diabetic foot is slow and often lingers without healing for a long time. The main causes of diabetic foot are the combined effects of microvascular lesions and peripheral nerve compression. With the aging of the population, the incidence of diabetic foot is increasing continuously, and the non-healing rate of wounds is also getting higher and higher. Due to the lack of effective treatment, this will develop into a serious social problem. Based on the current treatment status of diabetic foot, debridement to remove necrotic tissue, triple neurolysis, stem cell transplantation, lower limb vascular bypass, and tibial transverse bone transport technology are common methods for the treatment of this disease. However, the above treatment methods have great difficulties in professional technical operations and require high treatment costs, and cannot fundamentally meet the disease treatment needs of all patients.

[0003] In recent years, the tibial transverse bone transport technology has been widely used in clinical wound treatment, especially for the refractory ulcer wounds of diabetic foot, which has a unique curative effect. The tibial transverse bone transport technology is a therapy developed on the basis of the Ilizarov tension-stress method. This therapy can slowly and continuously stretch the bone, thereby stimulating cell proliferation and biosynthesis functions to a certain extent, having a relatively positive impact on promoting tissue regeneration, and promoting the metabolism of new tissues and the recovery of normal tissue functions to a certain extent.

[0004] For example, CN210056111U discloses a transverse bone transport device, which adjusts the horizontal distance of the bone nails on the upper bracket to adapt to the actual fixation area of various patients, and uses the lower bracket that moves up and down for stimulation treatment to improve blood supply to the lower limbs, and has a simple structure. However, the deficiencies of using the tibial external fixator device for the tibial transverse bone transport technology are as follows: on the one hand, since the existing transverse bone transport devices usually open all the fixation bone nails on the tibia, there are many wounds. At the same time, a part of the tibia is intercepted for transverse bone transport. Since the tibia is the main weight-bearing bone of the lower limb, it is easy to cause fractures due to osteotomy, which affects the limb movement function. In some cases after surgery, the skin at the transport area cracks and necroses, and bone exposure occurs due to many wounds. On the other hand, the tibia is located under the skin tissue, with less coverage of the medial skin tissue and fewer surrounding capillaries. Therefore, the angiogenesis generated by tibial transverse bone transport has certain limitations, and the improvement of blood circulation in diabetic foot is poor. Summary of the Invention

[0005] The object of the present invention is to overcome the problems of easy fracture after transverse tibial bone transport, skin cracking and necrosis in the transport area, bone exposure and other sequelae, and limited improvement of blood circulation. The present invention provides a lateral fibular bone transport external fixator device and its use method. The present invention sets the fixed end on the tibia, reduces the number of wound openings on the tibia side, does not affect the load-bearing capacity of the tibia after surgery, and sets the bone transport operation on the fibular side to achieve lateral fibular bone transport. The present invention only needs a minimally invasive incision within 5 mm to complete fibular osteotomy, further reducing the wound area, reducing wound infection at the fibular site, reducing complications, and at the same time, there is a richer capillary basis for bone transport at the fibular end, and the effect of repairing blood circulation is better.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A lateral fibular bone transport external fixator device, comprising a fibular transport device, a tibial fixation device and a connecting device, wherein the fibular transport device and the tibial fixation device are connected by the connecting device.

[0008] The fibular transport device includes a fixed seat provided on the connecting device, a fibular transport frame movably penetrating through the fixed seat, and an adjusting device provided on the fixed seat for adjusting the relative movement of the fibular transport frame with respect to the fixed seat.

[0009] Further, the fibular transport frame includes an adjusting screw vertically penetrating the fixed seat, a moving block fixedly connected to the adjusting screw, and a fibular fixing rod provided on the moving block; the adjusting device includes an adjusting nut, the adjusting nut is sleeved on the adjusting screw and is movably connected to the fixed seat, and the adjusting nut is provided with a thread matching the adjusting screw.

[0010] In this way, the adjusting screw and the moving block are connected to form a stable T-shaped structure. By rotating the adjusting nut, the adjusting screw is driven to move along the axis, driving the moving block to move vertically close to or away from the fixed seat along the direction of the adjusting screw. The fibular fixing rod is fixedly connected to the bone block of the fibular osteotomy segment, and the movement of the moving block drives the synchronous translation of the fibular fixing rod, thereby realizing the transverse transport process of the bone block of the fibular osteotomy segment.

[0011] Further, the fibular fixing rod includes two fibular fixing bone pins, the diameter of the fibular fixing bone pins is 1.7 mm - 2.5 mm, one end of the fibular fixing bone pins is provided with a thread and the fibular fixing bone pins are parallel to the adjusting screw. In this way, the diameter of the fibular fixing bone pins is small, and only a minimally invasive incision within 5 mm is required to complete fibular osteotomy, resulting in a small wound area and significantly reducing postoperative wound sequelae.

[0012] Furthermore, a fastening bolt for locking the adjusting screw is also provided at a position on the fixed seat corresponding to the adjusting screw.

[0013] It should be noted that the fibula fixing bone needle can also penetrate the fixed seat and be slidably connected to the fixed seat. The number of fastening bolts can be one or more. The fastening bolts are respectively used to fix the adjusting screw and the fibula fixing bone needle, which does not affect the achievement of the purpose of the present invention.

[0014] In this way, during the adjustment of the lateral transportation position of the fibula, due to the vibration and collision generated by the patient during daily activities, the fastening bolt can ensure the relative position stability of the connecting components on the fixed seat, and the accuracy of the bone block transportation and traction movement of the fibula osteotomy segment will not be affected.

[0015] Furthermore, the tibia fixing device includes a tibia fixing frame and a deviation correction adjusting device provided on the tibia fixing frame. The deviation correction adjusting device is connected to the connecting device.

[0016] Furthermore, the tibia fixing frame includes two tibia fixing bone needles. The diameter of the tibia fixing bone needles is 3.0 mm - 3.5 mm. One end of the tibia fixing bone needles is provided with threads and the two tibia fixing bone needles are parallel to each other. The deviation correction adjusting device includes a connecting rod and a plurality of fixing clips movably provided on the connecting rod. The fixing clips are respectively connected to the tibia fixing bone needles and the connecting device. In this way, the tibia fixing bone needles are locked into the appropriate position of the tibia through the threaded end. The diameter of the tibia fixing bone needles can generate sufficient supporting force. The tibia fixing bone needles are connected through the deviation correction adjusting device to form a rigid support bracket at the tibia end. The tibia can provide sufficient supporting force to provide a force-bearing support point for the fibula transportation device. At the same time, the deviation correction device can adjust the fixing positions of the tibia fixing bone needles and the connecting device according to the actual operation requirements, and determine the optimal installation position through deviation correction fine-tuning.

[0017] Furthermore, the connecting device includes two arc-shaped round bars, and the central angle of the arc-shaped round bars is 70° - 95°. In this way, one end of the two arc-shaped round bars is fixed to both ends of the fixed seat in the fibula transportation device, and the other end of the two arc-shaped round bars is fixed to the connecting rod through the fixing clips of the deviation correction device to form an arc-shaped space bracket. A certain angle of the arc-shaped round bars can better transfer the supporting force at the tibia end to the transportation device at the fibula end. At the same time, different angles can be suitable for the leg conditions of different patients.

[0018] It should be noted that for the tibial fixation device provided at the tibial end, the area where the wound is generated is only the locking inlet of the tibial fixation frame. The tibial end support force extends to above the bone block of the contralateral fibular osteotomy segment through the connecting device. The tibial fixation device serves as the fulcrum of the traction support for the fibular transverse bone transport device, and the fibular transport frame serves as the transport device, avoiding the problem that all the previous surgical wounds and osteotomy segments were located on the tibial side, and will not affect the load-bearing capacity of the tibia after surgery.

[0019] The present invention also provides a method for using a fibular transverse bone transport external fixation frame device, which specifically includes the following steps:

[0020] S1 Device installation: First, select a suitable position on the fibula and vertically lock the threaded end of the fibular fixation rod onto the surface of the fibula. Use a micro-osteotome to perform fibular osteotomy at the outer ends above and below the locking position of the fibular fixation rod. Then, fixedly connect the fibular fixation rod and the adjusting screw to the moving block in sequence. Generally, flat head pins can be used to fixedly connect the adjusting screw and the moving block to form a fibular transport frame. Then, sequentially sleeved a fixed seat and an adjusting nut on the adjusting screw to complete the assembly of the fibular transport device. Then, select a suitable position on the tibia and vertically lock the threaded end of the tibial fixation frame onto the surface of the tibia, and adjust the other end of the tibial fixation frame to a suitable position and fix it to the connecting rod to complete the assembly of the tibial fixation device. Finally, fixedly connect one end of the connecting device to the fixed seat, and adjust the other end of the connecting device to a suitable position and fix it to the connecting rod to form the final fibular transverse bone transport external fixation frame device;

[0021] S2 Bone block transportation: Rotate the adjusting nut to move the fibular transport frame away from the fibula by a certain distance to complete one offset. Use a fastening bolt to fix the position of the adjusting screw after the offset. Repeat the transportation operation multiple times at regular intervals, with the same offset distance each time. The bone block of the fibular osteotomy segment is pulled outward relative to the fibula along with the fibular transport frame. When the blood supply repair is completed, stop the transportation and maintain it for a certain number of days;

[0022] S3 Bone block moving back: Move the bone block of the fibular osteotomy segment back to its original position according to the reverse operation steps of step S2;

[0023] S4 Device disassembly: Disassemble the fibular transverse bone transport external fixation frame device and store it for future use.

[0024] It should be noted that since the fibula is located deep in the skin fascia and is wrapped by the anterior and posterior muscle groups of the fibula, there is a richer capillary basis for bone transport at the fibula, the effect of repairing blood supply is better, and it is not easy to be infected. On the other hand, the fibula only bears 1 / 7 of the limb weight under load and is not the main load-bearing bone. After the fibula is transected, it does not affect the load-bearing walking function, and early ambulation can be carried out, which has strong practicability.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] (1) Compared with the existing tibial lateral bone transport device, in the tibial side of the present invention, only two tibial fixation pins are implanted as support points, and the fibular lateral bone transport external fixator is extended to the fibular side to provide traction support, resulting in less damage to the main load-bearing bone tibia and less skin tissue wound surface on the tibial surface;

[0027] (2) The present invention uses the fibular side for lateral bone transport. The fibular transport device acts on the transected bone of the fibula. By rotating the adjusting nut, the fibular fixation rod on the moving block moves synchronously, adjusting the transport distance of the fibular osteotomy, with precise control and convenient operation;

[0028] (3) The present invention performs osteotomy on the fibular side. The diameter of the fibular fixation pin used is small, and a minimally invasive incision within 5 mm is only required to complete the fibular osteotomy, further reducing the wound area, reducing wound infection at the fibular site, and reducing complications.

[0035] In the present invention, unless otherwise clearly defined and limited, terms such as "assembled", "connected", and "joined" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection; it may be a direct connection, or it may be connected through an intermediate medium, and it may be the internal connection and communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings.

[0037] Embodiment 1

[0038] As Figure 1 and Figure 2 shown, a lateral fibular bone transport external fixator device includes a fibular transport device, a tibial fixation device, and a connection device. The fibular transport device and the tibial fixation device are connected by the connection device.

[0039] In this embodiment, the fibular transport device includes a fixed seat 6 provided on the connection device, a fibular transport frame movably penetrating through the fixed seat 6, and an adjustment device provided on the fixed seat 6 for adjusting the movement of the fibular transport frame relative to the fixed seat 6.

[0040] In this embodiment, the fibular transport frame includes an adjustment screw rod 9 vertically penetrating through the fixed seat 6, a moving block 7 fixedly connected to the adjustment screw rod 9, and a fibular fixation rod provided on the moving block 7;

[0041] The adjustment device of this embodiment includes an adjustment nut 8. The adjustment nut 8 penetrates through the adjustment screw rod 9 and is movably connected to the fixed seat 6. The adjustment nut 8 is provided with threads that cooperate with the adjustment screw rod 9.

[0042] In this way, the adjustment screw rod 9 and the moving block 7 are connected to form a stable T-shaped structure. By rotating the adjustment nut 8, the adjustment screw rod 9 is driven to move along the axis, and at the same time, the moving block 7 is driven to vertically approach or move away from the fixed seat 6 along the direction of the adjustment screw rod 9. The fibular fixation rod is fixedly connected to the bone block of the fibular osteotomy segment. The movement of the moving block 7 drives the synchronous translation of the fibular fixation rod, thereby realizing the lateral transport process of the bone block of the fibular osteotomy segment.

[0043] In this embodiment, the fibular fixation rod is two fibular fixation pins 4. The diameter of the fibular fixation pins 4 is 2.0 mm. One end of the fibular fixation pins 4 is provided with threads and the fibular fixation pins 4 are parallel to the adjustment screw rod 9. The two fibular fixation pins 4 simultaneously penetrate through the fixed seat 6 and are slidably connected to the fixed seat 6. In this way, the diameter of the fibular fixation pins 4 is small, and a minimally invasive incision within 5 mm is only required to complete the fibular osteotomy, resulting in a small wound surface, which can greatly reduce the postoperative wound surface sequelae.

[0044] In this embodiment, three fastening bolts 12 are further provided on the fixing base 6 at positions corresponding to the adjusting screw rod 9 and the fibula fixing bone pin 4. In this way, during the adjustment of the transverse transportation position of the fibula, since vibrations and knocks will occur when the patient performs daily activities, the fastening bolts 12 can ensure the relative positions of the connecting components on the fixing base 6 are stable, and the accuracy of the traction movement of the bone block of the fibula osteotomy segment will not be affected.

[0045] In this embodiment, the tibia fixing device includes a tibia fixing frame and a deviation correction adjusting device provided on the tibia fixing frame. The deviation correction adjusting device is connected to the connecting device. The tibia fixing frame includes two tibia fixing bone pins 3. The diameter of the tibia fixing bone pins 3 is 3.3 mm. One end of the tibia fixing bone pins 3 is provided with threads and they are parallel to each other. The deviation correction adjusting device includes a connecting rod 2 and a plurality of fixing clips 5 movably provided on the connecting rod 2. The fixing clips 5 are respectively connected to the tibia fixing bone pins 3 and the connecting device.

[0046] In this way, the tibia fixing bone pins 3 are locked into the appropriate positions of the tibia through the threaded ends. The diameter of the tibia fixing bone pins 3 can generate sufficient supporting force. The tibia fixing bone pins 3 are connected through the deviation correction adjusting device to form a rigid support bracket at the tibia end. The tibia can provide sufficient supporting force to provide a force-bearing support point for the fibula transportation device. At the same time, the deviation correction device can adjust the fixing positions of the tibia fixing frame and the connecting device according to actual operation requirements, and the optimal installation position can be determined through deviation correction fine-tuning.

[0047] In this embodiment, the connecting device includes two arc-shaped round bars 1, and the central angle of the arc-shaped round bars 1 is 90°.

[0048] In this way, one end of the two arc-shaped round bars 1 is fixed to both ends of the fixing base 6 in the fibula transportation device, and the other end of the two arc-shaped round bars 2 is fixed to the connecting rod 2 through the fixing clips 5 of the deviation correction device to form an arc-shaped space bracket. A certain angle of the arc-shaped round bars 2 can better transmit the supporting force at the tibia end to the transportation device at the fibula end. At the same time, different angles can be suitable for the leg conditions of different patients.

[0049] It should be noted that for the tibia fixing device provided at the tibia end, the wound surface is only the locking inlet of the tibia fixing frame. The supporting force at the tibia end extends to the upper part of the other fibula osteotomy segment through the connecting device, serving as the pulling bracket for the fibula transverse bone transportation device, avoiding the problem that the previous surgical wound surface and the osteotomy segment are all located on the tibia side, and will not affect the load-bearing capacity of the tibia after surgery.

[0050] Embodiment 2

[0051] This embodiment is similar to Embodiment 1, except that in this embodiment, the diameter of the fibula fixation bone pin 4 is 1.7 mm, the diameter of the tibia fixation bone pin 3 is 3.0 mm, and the central angle of the arc-shaped round bar 1 is 70°. The structures and working principles of other parts of this embodiment are the same as those of Embodiment 1.

[0052] Embodiment 3

[0053] This embodiment is similar to Embodiment 1, except that in this embodiment, the diameter of the fibula fixation bone pin 4 is 2.5 mm, the diameter of the tibia fixation bone pin 3 is 3.5 mm, and the central angle of the arc-shaped round bar 1 is 95°. The structures and working principles of other parts of this embodiment are the same as those of Embodiment 1.

[0054] Embodiment 4

[0055] As Figure 3 shown, this embodiment provides a method for using the fibular transverse bone transport external fixation device according to any one of Embodiments 1-3. The specific operation steps are as follows:

[0056] S1 Device installation: First, select a suitable position on the fibula and vertically lock the threaded end of the fibula fixation bone pin 4 onto the surface of the fibula. Use a micro-osteotome to perform fibula osteotomy at the outer ends of the upper and lower sides of the locking position of the fibula fixation bone pin 4. Generally, the two osteotomy lines are 8 cm apart. One end of the adjusting screw 9 is fixedly connected to the moving block 7 through a flat head pin 10, and then the fibula fixation bone pin 4 is fixedly connected to the moving block 7 to form a fibula transport frame. Then, a fixed seat 6 and an adjusting nut 8 are sequentially sleeved on the adjusting screw 9 to complete the assembly of the fibula transport device;

[0057] Then, select a suitable position on the tibia and vertically lock the threaded end of the tibia fixation bone pin 3 onto the surface of the tibia. Adjust the other end of the tibia fixation bone pin 3 to a suitable position and fix it to the connecting rod 2 through a fixing clip 5 to complete the assembly of the tibia fixation device;

[0058] Finally, fix one end of the two arc-shaped round bars 1 to both ends of the fixed seat 6 through nuts 11, and adjust the other ends of the two arc-shaped round bars 1 to suitable positions and fix them to the connecting rod 2 through fixing clips 5 to form the final fibular transverse bone transport external fixation device;

[0059] S2 Bone block transportation: Rotate the adjusting nut 9 to move the fibula transportation frame away from the fibula by a certain distance to complete one offset. Use the fastening bolt 12 to fix the position of the adjusting screw 9 after the offset. Repeat the transportation operation multiple times at regular intervals. The offset distance is the same each time. Generally, it needs to be repeated 3 - 5 times, and the offset distance each time is between 0.25 mm and 0.30 mm. The bone block of the fibular osteotomy segment is pulled outwards relative to the position of the fibula along with the fibula transportation frame. When the blood supply repair is completed, stop the transportation and maintain for a certain number of days, usually 5 - 7 days;

[0060] S3 Bone block moving back: Move the bone block of the fibular osteotomy segment back to its original position according to the opposite operation steps of step S2 to complete one transportation cycle;

[0061] S4 Device disassembly: Disassemble the external fixation device for transverse fibula bone transportation and store it for future use.

[0062] It should be noted that since the fibula is located deep in the skin fascia and is wrapped by the anterior and posterior muscle groups of the fibula, there is a richer capillary basis for bone transportation at the fibula, and the effect of repairing blood supply is better. At the same time, it is not easy to be infected. On the other hand, the fibula only bears 1 / 7 of the limb weight under load and is not the main load-bearing bone. After the fibula is transected, it does not affect the load-bearing walking function, and early ambulation can be carried out, which has strong practicability.

[0063] Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
