Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and in particular to a tibial transverse bone transport device. Background Technology
[0002] Tibial transverse bone transport is an innovative orthopedic surgical technique primarily used to treat lower limb ischemic diseases, such as diabetic foot, lower limb arteriosclerosis obliterans, and chronic non-healing traumatic wounds of the foot and ankle in the elderly. Based on Ilizanov's tension-stress law, tibial transverse bone transport effectively stimulates the regeneration of lower limb tissues, especially the vascular system, by generating slow traction on biological tissues. This regenerative process helps patients regenerate a new microvascular system, thereby restoring lower limb blood circulation and alleviating tissue necrosis caused by vascular occlusion. This surgical method primarily uses minimally invasive techniques to maximize the preservation of lower limb function, reduce the risk of amputation, significantly improve the condition of patients with lower limb ischemic diseases, and enhance their quality of life.
[0003] In tibial transverse bone transport surgery, the surgeon first creates a small, controlled bone trauma on the patient's tibia. Through osteotomy, a square bone block approximately 1.5 x 5 cm on each side is opened. Then, using a special scaffold, the bone block is continuously pulled at a rate of 1 mm per day for two weeks to promote lower limb angiogenesis. Next, the surgeon returns the bone block to its original position at the same rate, completing the entire surgical procedure.
[0004] Tibial transverse bone transport devices are one of the important medical instruments in tibial transverse bone transport surgery. Current tibial transverse bone transport devices mainly use external fixation supports for bone transport. Specifically, the surgeon performs an osteotomy on the anteromedial aspect of the proximal tibia, installs fixation pins on the osteotomy fragments, and then fixes a mounting plate using an external fixation device. Adjusting screws are installed on the mounting plate, and the position of the fixation pins is gradually adjusted using these screws to achieve the desired bone transport effect.
[0005] However, existing external fixation devices have significant drawbacks. First, the procedure requires multiple punctures of the fixation pins, increasing surgical trauma and potentially damaging the periosteum, thus affecting bone regeneration. Second, the external fixator needs to be worn for an extended period, typically at least four weeks, during which patients must regularly clean the pin tracts to prevent infection. This is particularly difficult for elderly patients with limited mobility, significantly reducing their quality of life and comfort. Furthermore, the bulky and externally mounted external fixator is prone to collisions and interference with the external environment, making maintenance difficult, impacting daily life, and increasing the risk of accidents. Utility Model Content
[0006] To reduce surgical trauma and lower the risk of infection, this application provides a tibial transverse bone transport device.
[0007] The tibial transverse bone transport device provided in this application adopts the following technical solution:
[0008] A transverse tibial bone transport device includes a transport plate, wherein the transport plate is provided with a first locking screw for fixed connection with the tibia, and the first locking screw is slidably connected to the transport plate;
[0009] The side of the transfer plate is provided with a balloon groove, and an inflatable balloon is disposed in the balloon groove. A connecting catheter for injecting and withdrawing contrast agent into the inflatable balloon is connected to the inflatable balloon. A contrast agent infusion mechanism and a pressure detection mechanism for monitoring the pressure inside the inflatable balloon are respectively connected to the connecting catheter.
[0010] The transfer plate is also provided with a second locking screw for fixing it to the osteotomy block.
[0011] During use, an incision is made at the lesion site, the subcutaneous soft tissue is dissected, the periosteum is exposed and preserved, and an osteotomy is performed on the anteromedial aspect of the proximal tibia to create a rectangular osteotomy block approximately 5 cm long and 1.5 cm wide. The transport plate is implanted on the lateral side of the tibia, the first locking screw is fixed to the tibia, and the second locking screw is fixed to the osteotomy block. The osteotomy block is completely detached from the tibia. By injecting contrast agent into the inflatable balloon, the balloon expands and moves the transport plate away from the tibia. The transport plate moves the osteotomy block, producing a bone transport effect. When the contrast agent is withdrawn from the inflatable balloon, the balloon retracts, producing a reverse movement.
[0012] By adopting the above technical solution, the transfer plate can be embedded in the subcutaneous soft tissue. After suturing the wound, it greatly reduces the exposure of bone wounds and the trauma of pin tracks in the subcutaneous soft tissue, thereby significantly reducing the risk of infection and improving the healing effect of the surgery. Moreover, the entire device is compact and small, without large screw structures externally placed on the lower leg, which facilitates maintenance, reduces the risk of accidental collisions, and improves the patient's quality of life and comfort.
[0013] This technical solution utilizes an inflatable balloon design, allowing for precise control of its expansion and contraction via an external or internal control system. This eliminates the need for frequent adjustments to the fixation pin position and enables automated, timed adjustments, achieving intelligent monitoring and control. By using the expansion and contraction of the balloon to achieve bone transport, this solution simplifies the surgical procedure, shortens the operation time, and reduces the workload of the surgeon, eliminating the need for complex mechanical adjustments.
[0014] Optionally, the transfer plate is a long strip, and the transfer plate is made of steel plate or titanium alloy plate; the two ends of the transfer plate have rounded corners.
[0015] By adopting the above technical solutions, the elongated, plate-shaped transport plate not only possesses sufficient strength and rigidity to ensure structural stability during bone transport, but also features rounded corners at both ends to reduce irritation and damage to surrounding tissues, improving patient comfort during postoperative recovery. Using steel plates or titanium alloys to manufacture the transport plate further enhances biocompatibility and corrosion resistance, extending the instrument's lifespan.
[0016] Optionally, the transfer plate has first mounting holes at both ends, and the first locking screw has two screws that are respectively inserted into the two corresponding first mounting holes. The two first locking screws are arranged in parallel and spaced apart. The shank of the first locking screw is a smooth, blunt-tipped cylinder. The cap of the first locking screw abuts against the side of the transfer plate to form a limiting structure.
[0017] By adopting the above technical solution, the force balance of the transfer plate is ensured, the support is firm, and the slippage or displacement of the transfer plate is prevented; thus, the stability of the entire device structure is guaranteed, and the stable and reliable transfer of the osteotomy block is achieved. The first locking screw has a smooth, blunt-tipped cylinder, which reduces damage to the bone and periosteum, thereby maximizing the protection of the periosteum and reducing surgical trauma.
[0018] Optionally, the transfer plate has a second mounting hole in the middle for installing the second locking screw. The second locking screw is locked on the transfer plate. There are at least two second locking screws arranged in a cross-shaped oblique arrangement. The shank of the second locking screw is a smooth, blunt-headed cylinder.
[0019] By adopting the above technical solution, the cross-tilted design of the second locking screw makes the fixation more stable, effectively preventing the osteotomy block from shifting or loosening during transport, ensuring the precision and safety of the surgery. The shank of the second locking screw is a smooth, blunt-tipped cylinder, which reduces damage to surrounding tissues, especially the periosteum, facilitating postoperative recovery and reducing the risk of infection.
[0020] Optionally, there are two balloon grooves symmetrically arranged at or near the two ends of the transfer plate; each balloon groove contains an inflatable balloon, and the connecting catheter is connected in series with the two inflatable balloons.
[0021] By adopting the above technical solution, the two symmetrically arranged balloon grooves and the inflatable balloons inside them can more evenly distribute the force application points, ensuring more balanced force during bone transport, thereby improving the stability and accuracy of bone transport. The design of connecting the catheter in series with the two inflatable balloons allows the contrast agent to flow between the two balloons, achieving synchronous expansion and contraction, further enhancing the coordination and reliability of the system, and reducing the risk caused by excessive local pressure in a single balloon.
[0022] Optionally, the connecting conduit is arranged along the length of the transfer plate, one end of the connecting conduit extends out of the end face of the transfer plate and is provided with a first interface and a second interface respectively; the contrast agent infusion mechanism is external, the contrast agent infusion mechanism includes a solvent container and an infusion pump, the infusion pump is connected to the solvent container and the first interface of the connecting conduit respectively; the pressure detection mechanism is a pressure gauge connected to the second interface of the connecting conduit.
[0023] By employing the above technical solution, the connecting catheter is positioned away from the bone trauma site and externally connected, reducing the risk of infection of the bone wound. An external contrast agent infusion mechanism and pressure monitoring mechanism control the inflation size of the balloon, ensuring the safety and accuracy of the procedure.
[0024] Optionally, the contrast agent infusion mechanism is built-in, and the contrast agent infusion mechanism includes a controller, a power source, a contrast agent reservoir, and a micro pump; the micro pump is connected to the contrast agent reservoir and the connecting catheter respectively, and the pressure detection mechanism is a pressure sensor disposed in the inflatable balloon or the connecting catheter.
[0025] By adopting the above technical solution, the contrast agent infusion mechanism is built-in, which makes the whole system more integrated, reduces the number and complexity of external equipment, and achieves the smallest incision and the lowest risk of exposure and infection, thereby improving patient comfort and healing effect.
[0026] Optionally, the pressure sensor is connected to the controller, and the controller is connected to a wireless signal transmitting and receiving module.
[0027] By employing the above-mentioned technical solution, precise monitoring of the internal pressure of the inflatable balloon is achieved, ensuring uniform force distribution and accurate monitoring and control of the transport volume during bone transport, thus improving the safety and reliability of the surgery. Simultaneously, the design of the wireless signal transmitting and receiving module allows doctors to obtain real-time pressure data of the inflatable balloon externally, further reducing uncertainties during surgical procedures, lowering the risk of infection, and enhancing the overall patient experience.
[0028] Optionally, a displacement sensor is also provided on the side of the transfer plate, and the displacement sensor is connected to the controller.
[0029] By employing the above technical solution, the displacement sensor can monitor the moving distance and speed of the transport plate in real time during bone transport, ensuring the accuracy and controllability of the process. Combined with the controller's functions, automated control of the bone transport process can be achieved, further improving surgical safety and efficiency and reducing human error. Simultaneously, data feedback from the displacement sensor helps doctors adjust surgical parameters promptly, optimizing treatment outcomes.
[0030] Optionally, the connecting conduit is provided with a fixing ring loop.
[0031] By adopting the above technical solution, the connecting catheter is fixed by a fixing ring loop, reducing its displacement and ensuring the stability and reliability of the entire surgical procedure.

[0050] The following will be combined with the appendix Figure 1 -Appendix Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.
[0051] The device described in this application is primarily intended for the treatment of Wagner grade 3-4 diabetic foot, chronic lower limb ischemic diseases (such as thromboangiitis obliterans and arteriosclerosis obliterans), and long-term non-healing traumatic wounds of the foot and ankle in the elderly. These conditions typically require surgical intervention to restore blood circulation and promote wound healing. Traditional treatments often rely on open surgery, which, while effectively addressing circulation issues, leads to numerous postoperative complications, prolonged recovery periods, and impacts patients' quality of life.
[0052] Example 1
[0053] Reference Figure 1 and Figure 2 As shown in the illustration, the tibial transverse bone transport device provided in this application includes a transport plate 10. The transport plate 10 is a long strip plate, made of steel plate or titanium alloy plate to ensure that the transport plate 10 has sufficient strength and rigidity, as well as ensuring its biocompatibility and corrosion resistance, thus extending its service life. The two ends of the transport plate 10 have rounded corners to reduce damage to human tissues.
[0054] Reference Figure 1 and Figure 2As shown, the transfer plate 10 has first mounting holes 11 at both ends. The transfer plate 10 is provided with two first locking screws 20 for fixing to the tibia. Each first locking screw 20 is inserted into one of the two corresponding first mounting holes 11 and is slidably connected to the transfer plate 10. The two first locking screws 20 are arranged parallel and spaced apart. The shaft of each first locking screw 20 is a smooth, blunt-tipped cylinder. The cap of each first locking screw 20 abuts against the side of the transfer plate 10 to form a limiting structure. The transfer plate 10 is also provided with second locking screws 30 for fixing to the osteotomy piece. A second mounting hole 12 is provided in the middle of the transfer plate 10 for installing the second locking screws 30. The second locking screws 30 are locked onto the transfer plate 10. There are at least two second locking screws 30 arranged in a cross-shaped, inclined manner, and the shaft of each second locking screw 30 is a smooth, blunt-tipped cylinder. The aforementioned structure ensures the force balance of the transfer plate 10, provides firm support, and prevents the transfer plate 10 from slipping or shifting; thus, it ensures the stability of the entire device structure and enables stable and reliable transfer of the osteotomy block. The first locking screw 20 and the second locking screw 30 have smooth, blunt-tipped cylindrical shafts, reducing damage to the bone and periosteum, thereby maximizing the protection of the periosteum and reducing surgical trauma.
[0055] Reference Figure 2 and Figure 3 As shown, the transport plate 10 has balloon grooves 13 on its side, and an inflatable balloon 40 is placed inside the balloon grooves 13. A connecting catheter 50 for injecting and withdrawing contrast agent into the inflatable balloon 40 is connected to the inflatable balloon 40. A fixing ring loop is provided on the connecting catheter 50 to fix the connecting catheter 50, reduce its displacement, and ensure the stability and reliability of the entire surgical procedure. A contrast agent infusion mechanism 60 and a pressure detection mechanism 70 for monitoring the pressure inside the inflatable balloon 40 are respectively connected to the connecting catheter 50. Furthermore, there are two balloon grooves 13 symmetrically arranged at or near the two ends of the transport plate 10. Each balloon groove 13 contains an inflatable balloon 40, and the connecting catheter 50 is connected in series with the two inflatable balloons 40. The two symmetrically arranged balloon grooves 13 and the inflatable balloons 40 inside them can distribute the force application point more evenly, ensuring more balanced force during bone transport, thereby improving the stability and accuracy of bone transport. The design of connecting catheter 50 in series with two inflatable balloons 40 allows the contrast agent to flow between the two balloons, achieving synchronous expansion and contraction, which further enhances the coordination and reliability of the system and reduces the risk caused by excessive local pressure in a single balloon.
[0056] Reference Figure 2 and Figure 3As shown, the connecting catheter 50 is arranged along the length of the transfer plate 10, with one end extending out of the end face of the transfer plate 10 and having a first interface 51 and a second interface 52 respectively. The contrast agent infusion mechanism 60 is external and includes a controller 64, an external power supply 63, a solvent container 61, and an infusion pump 62. The infusion pump 62 is connected to the solvent container 61 and the first interface 51 of the connecting catheter 50. The pressure detection mechanism 70 is a pressure gauge 71 connected to the second interface 52 of the connecting catheter 50. Both the pressure gauge 71 and the infusion pump 62 are electrically connected to the controller 64. The external power supply 63 supplies power to the infusion pump 62 and the controller 64. The connecting catheter 50 is located away from the bone trauma site and connected to the outside, reducing the risk of infection of the bone wound. The external contrast agent infusion mechanism 60 and the pressure detection mechanism 70 control the inflation size of the inflatable balloon 40, ensuring the safety and accuracy of the operation.
[0057] In this embodiment, a displacement sensor 80 is also provided on the side of the transfer plate 10, and the displacement sensor 80 is connected to the controller 64. The displacement sensor 80 is used to monitor the moving distance of the transfer plate 10, and to monitor the moving distance and speed of the transfer plate 10 in real time during the bone transfer process, ensuring the accuracy and controllability of the bone transfer process. Combined with the functions of the controller 64, the automated control of the bone transfer process can be realized, further improving the safety and efficiency of the surgery and reducing human error. At the same time, the data feedback from the displacement sensor 80 helps the doctor to adjust the surgical parameters in a timely manner and optimize the treatment effect.
[0058] The implementation principle of this embodiment is as follows: During use, an incision is made at the lesion site, the subcutaneous soft tissue is dissected, the periosteum is exposed and preserved, and an osteotomy is performed on the anteromedial aspect of the proximal tibia to create a rectangular osteotomy block approximately 5 cm long and 1.5 cm wide. The transport plate 10 is implanted on the lateral side of the tibia, the first locking screw 20 is fixedly connected to the tibia, and the second locking screw 30 is fixedly connected to the osteotomy block. The osteotomy block is completely detached from the tibia. By injecting contrast agent into the inflatable balloon 40, the inflatable balloon 40 expands and moves the transport plate 10 away from the tibia. The transport plate 10 moves the osteotomy block, producing a bone transport effect. When the contrast agent is withdrawn from the inflatable balloon 40, the inflatable balloon 40 retracts, producing a reverse movement.
[0059] The transfer plate 10 can be embedded in the subcutaneous soft tissue. After suturing the wound, it greatly reduces the exposure of bone wounds and the trauma of pin tracks in the subcutaneous soft tissue, thereby significantly reducing the risk of infection and improving the healing effect of the surgery. Moreover, the entire device is compact and small, without large screw structures external to the lower leg, which facilitates maintenance, reduces the risk of accidental collisions, and improves the patient's quality of life and comfort.
[0060] This technical solution utilizes an inflatable balloon 40, whose expansion and contraction can be precisely controlled by an external or internal control system. This eliminates the need for frequent adjustments to the fixation pin position and allows for automated, timed adjustment, achieving intelligent monitoring and regulation. This ensures the balloon 40 remains within a safe pressure range, preventing over-inflation or over-contraction due to improper human operation. Furthermore, the addition of an intelligent feedback system makes the treatment process more personalized, dynamically adjusting parameters based on the patient's actual condition to achieve optimal treatment results. This design not only improves the safety and effectiveness of the surgery but also helps shorten the recovery period, increases overall patient satisfaction, and reduces the workload of doctors.
[0061] Example 2
[0062] Reference Figure 4 As shown, this embodiment is largely the same as Embodiment 1, except that the contrast agent infusion mechanism 60 in this embodiment is built-in. The contrast agent infusion mechanism 60 includes a controller 64, a power source 65, a contrast agent reservoir 66, and a micro pump 67. The micro pump 67 is connected to the contrast agent reservoir 66 and the connecting catheter 50. The power source 65 can be a battery power supply or a built-in battery. The micro pump 67 is electrically connected to the controller 64 and the power source 65; or the power source 65 can be a mechanical power source. The pressure detection mechanism 70 is a pressure sensor 72 installed inside the inflatable balloon 40 or the connecting catheter 50. The pressure sensor 72 is connected to the controller 64, which is connected to a wireless signal transmitting and receiving module for external wireless signal transmission. A displacement sensor 80 is also installed on the side of the transfer plate 10, and the displacement sensor 80 is connected to the controller 64.
[0063] This embodiment features a built-in design for the contrast agent infusion mechanism 60, resulting in higher system integration, reduced number and complexity of external devices, minimal incision, and lowest risk of exposure and infection, thus improving patient comfort and healing outcomes. Furthermore, the wireless signal transmission and reception module allows physicians to obtain real-time pressure data of the inflatable balloon 40 externally, further reducing uncertainties during surgical procedures, lowering the risk of infection, and enhancing the overall patient experience.
