[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0045] Transverse tibial bone transport can stimulate the proliferation and biosynthesis functions of cells through slow and continuous tibial distraction, mobilize the body's self - repair ability, improve the blood supply of the foot, and promote the healing of ulcers on the lower leg and foot.

[0046] The working principle of bone transport is as follows: First, the surgeon performs an osteotomy at the target bone site, that is, cuts the bone but does not completely separate it. After the osteotomy, the doctor installs an external fixator at both ends of the bone. Then the doctor gradually adjusts the external fixator to gradually separate the two ends of the cut bone. During the traction process, the gap between the two ends of the bone will be gradually filled with newly generated bone tissue. When the bone is lengthened to the expected length, the external fixator will continue to maintain fixation until the newly generated bone tissue is complete

[0047] However, traditional bone transport devices only play the role of fixing and moving bone positions. The conventional healing at the transected position in the bone segment will hinder the traction process and affect the effect of bone transport.

[0048] Therefore, the present application provides a bone transport device. By fixedly arranging the first bone fixing member on the transected bone segment, and the first bone fixing member can drive the transected bone segment to move relative to the fixed bone segment so that the transected bone segment is separated from the fixed bone segment; fixedly arranging the second bone fixing member at both ends of the fixed bone segment, and using a fixed bracket to support the first bone fixing member and the second bone fixing member; injecting a medicament into the transected position of the transected bone segment by using the first drug delivery component to inhibit premature healing between the fixed bone segment and the transected bone segment. Compared with traditional bone transport devices, this device can inhibit the healing at the transected position in the bone segment and improve the bone transport effect.

[0049] The following further elaborates on a bone distraction device in this embodiment.

[0050] Figure 1 It is a schematic structural diagram of a bone distraction device provided by an embodiment of the present application.

[0051] The tibial transverse bone distraction technique is based on the principle of "tension-stress", which can stimulate and promote the regenerative ability of limb tissues, reconstruct local microvessels and nerves, and improve chronic ischemic diseases of the lower extremities.

[0052] A bone distraction device is a medical device used for treating bone defects or bone lengthening. Its basic principle is to gradually stretch bone tissue to stimulate the generation of new bone, thereby achieving bone lengthening or repair. During the bone distraction process, if the transected bone segment and the fixed bone segment grow together, it will cause bone bridge formation or premature callus formation, which will limit the movement between the transected bone segment and the fixed bone segment, or even completely block it, directly affecting the progress of bone distraction and unable to achieve the expected bone lengthening or repair effect. And due to the existence of the bone bridge, the stress during the bone distraction process cannot be effectively transmitted to the newly formed bone tissue, which may lead to nonunion, bone deformity, etc., affecting the patient's quality of life.

[0053] As Figure 1 shown, an embodiment of the present application provides a bone distraction device 10, including: a first bone fixation member 100, two second bone fixation members 200, a fixation bracket 300, and a first drug delivery assembly 400; wherein, an antibacterial coating can be provided on the surfaces of the first bone fixation member 100 and the second bone fixation members 200 to reduce the risk of infection.

[0054] The first bone fixation member 100 and the two second bone fixation members 200 are arranged at intervals and connected to the fixation bracket 300; wherein, in order to reduce the burden on the patient and improve comfort, the material of the fixation bracket 300 can be titanium alloy. The purpose of this setting is that titanium alloy has high strength, can provide sufficient mechanical support, ensure the stability and reliability of the bone distraction device, and titanium alloy also has the advantages of low density and light weight.

[0055] Specifically, a handle (not shown in the figure) is also provided on the fixation bracket 300. The operator can grab the handle to manually traction the transected bone segment 600 to move a preset distance regularly, so that the transected bone segment 600 is separated from the fixed bone segment 700. Specifically, the transected bone segment 600 can also be gradually tractioned to move through a traction mechanism to control the speed of bone distraction.

[0056] The first bone fixation member 100 is configured to be connected to the transected bone segment 600, and the second bone fixation members 200 are configured to be connected to the fixed bone segment 700 adjacent to the transected bone segment 600; the first bone fixation member 100 is configured to drive the transected bone segment 600 to move up and down relative to the fixed bone segment 700 along a first direction;

[0057] Wherein, the first direction is perpendicular to the axial direction of the fixed bone segment 700. During the treatment process, by gradually traction the transected bone segment 600, the gap between the transected bone segment 600 and the fixed bone segment 700 is continuously increased. Specifically, during the traction process, X-ray films should be taken regularly to adjust the traction speed at any time.

[0058] The first drug delivery component 400 is configured to inject a bone growth inhibitor, such as bisphosphonate or other drugs that inhibit the activity of osteoblasts, into the transected positions at both ends of the transected bone segment 600 to prevent unnecessary bone bridge formation.

[0059] In this way, by fixedly arranging the first bone fixation member 100 on the transected bone segment 600, and the first bone fixation member 100 can drive the transected bone segment 600 to move relative to the fixed bone segment 700, so that the transected bone segment 600 is separated from the fixed bone segment 700; the second bone fixation member 200 is fixedly arranged at both ends of the fixed bone segment 700, and the fixed bracket 300 is used to support the first bone fixation member 100 and the second bone fixation member 200; the first drug delivery component 400 is used to inject a drug into the transected position of the transected bone segment 600 to inhibit premature healing between the fixed bone segment 700 and the transected bone segment 600. Compared with the traditional bone distraction device, this device can inhibit premature healing at the transected position in the bone segment and improve the bone distraction effect.

[0060] In some embodiments, the first drug delivery component 400 includes a first drug storage device 410 and a first drug delivery pipeline 420. The first drug storage device 410 is communicated with the first drug delivery pipeline 420 to inject the drug in the first drug storage device 410 into the transected position of the transected bone segment 600 through the first drug delivery pipeline 420.

[0061] Wherein, as an optional implementation manner, the first drug delivery pipeline 420 is formed by sleeving a plurality of catheters with different diameters. The purpose of this setting is to adjust the length of the first drug delivery pipeline 420 according to needs to adapt to different space limitations, and can play a guiding role in the flow of the drug.

[0062] In some embodiments, the first drug delivery component 400 further includes a first drug delivery valve and a first drug delivery control member. The first drug delivery valve is arranged on the first drug delivery pipeline 420, the first drug delivery control member is arranged on the first drug storage device 410, and the first drug delivery control member is electrically connected to the first drug delivery valve for controlling the opening state and drug delivery flow rate of the first drug delivery valve.

[0063] Among them, as an optional implementation manner, the type of the first drug delivery valve is a micro-valve pump. Through the periodic opening and closing of the valve and the driving of the pump body, precise drug delivery is achieved. Specifically, a flow sensor (not shown in the figure) is further provided in the first drug storage device 410 to monitor the state of the liquid in real time, and the flow sensor is connected to the drug delivery control member. The drug delivery control member adjusts the state of the drug delivery valve according to the data fed back by the flow sensor to achieve the intelligent drug delivery function.

[0064] Among them, according to the individual differences of patients, the injection speed of the drug is controlled by the first drug delivery control member, so that the drug can be gradually released during the bone distraction process to continuously inhibit bone growth. Moreover, by controlling the injection speed of the drug through the drug delivery control member, local or systemic side effects caused by too fast injection speed of the drug can be prevented, and the treatment effect can be optimized.

[0065] In some embodiments, a second drug delivery assembly 500 is provided on at least one of the first bone fixation member 100 and the two second bone fixation members 200.

[0066] Among them, when fixing the bone fixation member, the first bone fixation member 100 and the second bone fixation member 200 will pass through the skin, soft tissue and bone, which may cause infection, resulting in nonunion, osteomyelitis, etc., seriously affecting the treatment effect.

[0067] Specifically, an anti-inflammatory drug is injected into the bone segment where the first bone fixation member 100 and the second bone fixation member 200 are fixed through the second drug delivery assembly 500 to prevent hazards such as wound infection and necrosis.

[0068] In some embodiments, there are multiple second drug delivery assemblies 500, and the multiple second drug delivery assemblies 500 are respectively connected to the first bone fixation member 100 and the two second bone fixation members 200 correspondingly. As Figure 1 shown, an anti-inflammatory drug is injected into the fixation part of the first bone fixation member 100 and the second bone fixation member 200 through the second drug delivery assembly 500 to prevent complications caused by pin tract infection.

[0069] In some embodiments, the second drug delivery assembly 500 includes a second drug storage device 510 and a second drug delivery pipeline 520. The second drug delivery pipeline 520 is communicated with the second drug storage device 510, so that the drug in the second drug storage device 510 can be transported into the truncated bone segment 600 and the fixed bone segment 700 through the second drug delivery pipeline 520.

[0070] Among them, the second drug storage device 510 is fixedly arranged at both ends of the second connecting plate 320, and the second drug storage device 510 is communicated with the second bone fixation member 200 through the second drug delivery pipeline 520.

[0071] In some embodiments, fluid channels are provided in both the first bone fixation member 100 and the second bone fixation member 200, and the second drug delivery tube 520 is disposed through the fluid channels.

[0072] Among them, as an alternative embodiment, the material of the second drug delivery tube 520 is selected as polyethylene. The purpose of this setting is that the drug delivery tube made of polyethylene material has good flexibility, which can ensure that the second drug delivery tube 520 can be smoothly placed into the fluid channel and can adapt to the bending and movement of the first bone fixation member 100 and the second bone fixation member 200.

[0073] Among them, the diameter of the fluid channel is larger than the diameter of the second drug delivery tube 520. The purpose of this setting is that the second drug delivery tube 520 can be smoothly placed into the fluid channel without causing blockage. Specifically, the inner surface of the fluid channel should have good smoothness.

[0074] In some embodiments, the fixing bracket 300 includes two first connecting plates 310, two second connecting plates 320 and a support rod 330. The two first connecting plates 310 are disposed at opposite ends of the support rod 330, and the support rod 330 surrounds the outer peripheral side of the first bone fixation member 100; the two second connecting plates 320 are fixedly connected to the support rod 330.

[0075] Among them, as Figure 1 shown, the first bone fixation member 100 longitudinally passes through the support rod 330, and the second bone fixation member 200 transversely passes through the outside of the support rod 330. Specifically, a card slot is provided on the second connecting plate 320, and the second connecting plate 320 is snap-connected to the support rod 330 through the card slot, having high stability.

[0076] Among them, a self-locking structure is further provided on the support rod 330. When the truncated bone segment 600 moves vertically to a preset distance, the self-locking structure is in a locked state to fix the position of the truncated bone segment 600.

[0077] In some embodiments, a first driving mechanism 340 is further provided in the fixing bracket 300. There are two first bone fixation members 100. The first driving mechanism 340 includes two first transmission gears 342 and a first driving gear 341. The two first bone fixation members 100 are correspondingly arranged with the two first transmission gears 342;

[0078] The first driving gear 341 is disposed between the two first transmission gears 342. The first driving gear 341 meshes with the two first transmission gears 342. The first bone fixation member 100 is fixedly connected to the first transmission gear 342. The first driving gear 341 is configured to drive the two first bone fixation members 100 to rotate in opposite directions around their own axes respectively.

[0079] Among them, the first driving gear 341 is detachably connected to the driving motor. When fixing the first bone fixing member 100, the output shaft of the driving motor is connected to the first driving gear 341, and the driving motor drives the first driving gear 341 to rotate, so that the two first transmission gears 342 meshing with the first driving gear 341 respectively rotate around their own axes. Among them, the rotation directions of the two first bone fixing members 100 are opposite. After the fixing is completed, the first driving gear 341 is disconnected from the driving motor, and the driving motor can be removed from the bone moving device 10.

[0080] In some embodiments, a second driving mechanism 350 is further provided in the fixing bracket 300. The second driving mechanism 350 includes a rack 353, a second driving gear 351 and a second transmission gear 352.

[0081] The rack 353 is arranged on the second connecting plate 320. The second driving gear 351 is arranged between the two second connecting plates 320, and the second driving gear 351 meshes with the rack 353 and is used to drive the rack 353 to move axially along the second connecting plate 320. The second bone fixing member 200 is fixedly arranged on the second transmission gear 352. The second transmission gear 352 meshes with the rack 353, and the second transmission gear 352 is configured to drive the second bone fixing member 200 to rotate around its own axis.

[0082] Among them, the second driving gear 351 is connected to the driving motor. The second driving gear 351 rotates under the action of the driving motor to drive the rack 353 meshing with the second driving gear 351 to perform reciprocating motion along the axis of the fixed bone segment 700. At the same time, the second transmission gear 352 located at the end of the rack 353 rotates under the action of the rack 353, so that the second bone fixing member 200 is screwed into the fixed bone segment 700.
