Description

Technical Field

[0001] This utility model relates to the field of orthopedic medical device technology, and in particular to a novel track-type bone transport device. Background Technology

[0002] Chinese patent document CN111134812A discloses a single-bar bone transport device. (See also...) Figure 11 The single-rod bone transport device includes a main structure 43, a rod clamp 48, and a bone needle 49. The main structure 43 includes a base rod and a sleeve 47. The base rod includes an adjustment section 45 in the middle and two separate sections 44 and a fixing section 46 at both ends. The sleeve 47 is slidably sleeved on the adjustment section 45. The adjustment section 45 is provided with an axially extending guide groove. A guide key that slides with the guide groove is detachably installed on the sleeve 47. The outer surface of the adjustment section 45 is provided with an external thread. The two ends of the sleeve 47 are respectively provided with a first nut and a second nut that are threaded together by the internal thread and the external thread. The sleeve 47 is driven to move axially by turning the first nut and the second nut. The rod clamp 48 and the bone needle 49 are installed on the separate section 44 to fix the proximal bone segment 38. The rod clamp 48 and the bone needle 49 are installed on the sleeve 47 to fix the free bone segment 39. The rod clamp 48 and the bone needle 49 are installed on the fixing section 46 to fix the distal bone segment 40. When in use, moving the sleeve 47 axially causes the bar needle clamp 48 and bone needle 49 on the sleeve 47 to slowly move the cut free bone segment 39 toward the bone defect, thereby stimulating the body tissue and forming new bone to achieve the purpose of bone lengthening.

[0003] In addition, see Figure 16 and Figure 17 Existing bone track-type bone transport devices include a track 1, a first clamp 2, a second clamp 3, and a third clamp 4. A set of bone screws mounted on the first clamp 2 is used to fix the proximal bone segment 38, a set of bone screws on the second clamp 3 is used to fix the free bone segment 39, and a set of bone screws on the third clamp 4 is used to fix the distal bone segment 40. In use, this bone track-type bone transport device also relies on manual adjustment of the distance between the clamps to adapt to different treatment needs. However, manual adjustment has drawbacks such as inconvenience and cumbersome operation. Specifically, frequent manual adjustments not only increase the burden on doctors or patients, but improper operation can also lead to loosening of the device or other mechanical malfunctions.

[0004] Therefore, there is an urgent clinical need for a new type of track-type bone transport device that is non-manual and easy to operate. Utility Model Content

Detailed Implementation

[0058] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 1 The orientation is for reference only, and is not the orientation used in actual use of the product in this patent.

[0059] Example 1:

[0060] Reference Figure 1 Figure 2 and Figure 3This embodiment provides a novel track-type bone transport device, including a track 1, an adjustment device, an electric drive device, a first clamping block 2, a second clamping block 3, a third clamping block 4, and a battery. In use, the track 1 is parallel to the long axis of the bone and located on the lateral side of the limb. It should be noted that the first clamping block 2, the second clamping block 3, and the third clamping block 4 are used to install bone screws, which penetrate the skin and are anchored within the bone. Specifically, a set of bone screws installed on the first clamping block 2 is used to fix the proximal bone segment 38, a set of bone screws on the second clamping block 3 is used to fix the free bone segment 39, and a set of bone screws on the third clamping block 4 is used to fix the distal bone segment 40. Since the fixation positions of the three sets of bone screws are still the proximal bone segment 38, the free bone segment 39, and the distal bone segment 40 in the prior art, therefore, refer to... Figure 11 , Figure 16 and Figure 17 Therefore, it is understood that a schematic diagram of the bone screw fixation position applicable to this embodiment is no longer provided.

[0061] A first clamping block 2, a second clamping block 3, and a third clamping block 4 are sequentially slidably mounted on track 1. Bone screws are installed on each of these three clamping blocks to fix the bone segment. A first connecting post 6 is provided on the second clamping block 3, and a second connecting post 7 is provided on the third clamping block 4. Adjustment devices are provided on the first connecting post 6 and the second connecting post 7, and these devices are used to move the second clamping block 3. The adjustment devices connect adjacent second clamping blocks 3 and third clamping blocks 4 and apply traction force along the long axis of the bone to the free bone segment 39, thereby achieving traction osteogenesis.

[0062] It should be noted that the function of the bone screw is similar to that of the bone needle 49 in the prior art. During the operation, a hole is first drilled in the bone with an electric drill, and then the end of the bone screw is screwed into the hole. The tail of the bone screw is fixed by a clamp.

[0063] The adjustment device includes a threaded rod 8, a fixing component, and an adjustment component. The threaded rod 8 passes through the first connecting post 6 and the second connecting post 7. One end of the threaded rod 8 is provided with the fixing component, and the other end is provided with the adjustment component and the electric drive device. The battery is electrically connected to the electric drive device, and the electric drive device is drively connected to the adjustment component. Thus, the power of the battery is converted into driving power for the second clamping block 3 to move along the track 1 through the electric drive device, the adjustment component, the threaded rod 8, and the fixing component, so that the second clamping block 3 moves the free bone segment 39 through the bone screw.

[0064] It should be noted that the battery is external and electrically connected to the electric drive device via wires. Furthermore, the battery is preferably a lithium battery or a button battery, which supplies power to the various electrical components. The electric drive device serves as the power source for the regulating device, used to drive the mechanized regulating mechanism.

[0065] The novel track-type bone transport device of this embodiment, due to the above-described structure, enables non-manual mechanical transport of bone segments, which is convenient to operate and reduces the workload of doctors or patients.

[0066] In this embodiment, the first clamping block 2 and the third clamping block 4 are used to fix the two ends of the defective bone, respectively, and the second clamping block 3 is used to fix the free bone segment 39.

[0067] Preferably, the electric drive device in this embodiment includes a drive motor 9, which is driven to be connected to an adjustment component. The adjustment component drives the threaded rod 8 to move axially, and then drives the first connecting column 6 and the second clamping block 3 to move along the track 1 through the fixing component.

[0068] Preferably, the third clamping block 4 is provided with a third connecting post 12, and a drive motor 9 is mounted on the third connecting post 12. The drive motor 9 is a servo motor or a stepper motor. In addition, it should be noted that the first clamping block 2, the second clamping block 3, and the third clamping block 4 are provided with connecting post holes 5, and connecting posts are detachably installed in the connecting post holes 5. That is to say, the first connecting post 6, the second connecting post 7, and the third connecting post 12 are inserted into the connecting post holes 5 one by one.

[0069] Preferably, the adjusting assembly includes a first scale sleeve 23, a first spring 24, a first adjusting sleeve 25, and an adjusting nut 26 sequentially fitted onto the threaded rod 8. One end of the first adjusting sleeve 25 is open, and the other end extends radially inward to form a first step. The first scale sleeve 23 is disposed inside the open end of the first adjusting sleeve 25, and the first adjusting sleeve 25 is slidably connected to the outer wall of the first scale sleeve 23. One end of the first spring 24 abuts against one end of the first scale sleeve 23, and the other end abuts against the inner wall of the first step of the first adjusting sleeve 25. The inner hole of the adjusting nut 26 is threadedly connected to the threaded rod 8, and a first meshing tooth is provided on the outer circumferential surface of the adjusting nut 26. A drive gear 27 is provided on the shaft of the drive motor 9, and the drive gear 27 meshes with the first meshing tooth on the adjusting nut 26 to drive the adjusting nut 26 to abut against the outer wall surface of the first step.

[0070] Preferably, the fixing component in this embodiment is a blocking nut 28, which is threadedly connected to the threaded rod 8.

[0071] Preferably, the novel track-type bone transport device of this embodiment further includes a plurality of clamping screws 16.

[0072] The upper part of the track 1 is provided with a dovetail groove 17. The bottom of the first clamping block 2, the second clamping block 3 and the third clamping block 4 are provided with T-shaped steps 18 that cooperate with the dovetail groove 17. The first clamping block 2, the second clamping block 3 and the third clamping block 4 can slide along the dovetail groove 17 on the track 1. The inside of the track 1 is also provided with a through groove 19 extending along the length direction. After multiple clamping block fixing screws 16 pass through the through groove 19, they are connected to the first clamping block 2, the second clamping block 3 and the third clamping block 4 one by one.

[0073] It should be noted that by tightening the clamp fixing screw 16, the head of the clamp fixing screw 16 abuts against the bottom surface of the track 1, thereby selectively fixing the first clamp 2, the second clamp 3 and / or the third clamp 4 in the track 1 and restricting their movement along the length direction of the track 1.

[0074] Please see Figure 2 and Figure 3 The first clamping block 2 specifically includes a first sub-clamping block 20 and a second sub-clamping block 21. A T-shaped step 18 is provided at the bottom of the second sub-clamping block 21, and the T-shaped step 18 is slidably disposed within the dovetail groove 17 of the track 1. The first sub-clamping block 20 is disposed above the second sub-clamping block 21 and is detachably connected together by bolts. Grooves for fixing bone screws are provided on the opposite sides of the first sub-clamping block 20 and the second sub-clamping block 21. Furthermore, it should be noted that the specific structures of the second clamping block 3 and the third clamping block 4 are the same as those of the first clamping block 2, and will not be described again here.

[0075] The working process of the novel track-type bone transport device in this embodiment is as follows: The drive motor 9 drives the adjusting nut 26 to rotate through the drive gear 27, which causes the adjusting nut 26 and the threaded rod 8 to undergo relative displacement in the axial direction. As a result, the threaded rod 8 drives the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby realizing the mechanical transport of the free bone segment 39. At the same time, the adjusting nut 26 abuts against the first adjusting sleeve 25, the first graduated sleeve 23, the first spring 24, and the second connecting post 7.

[0076] The outer wall of the first scale sleeve 23 has a traction force scale, which serves as a base reference and can be visually observed by the operator. The function of the first spring 24 is to provide elastic adjustment to simulate the natural biomechanical environment and apply low-frequency elastic stress within the physiological range to the patient. Compared with traditional rigid traction, it has the following significant advantages: continuous and gentle traction force, suitable for traction of soft tissue regeneration, easy to achieve tension, and less prone to jamming failure of the traction device.

[0077] This novel track-type bone transport device is applied to the long bones of the limbs (i.e., femur, tibia, and humerus), especially in areas with large bone defects (such as after trauma, infection, or tumor resection) or where bone lengthening is required. Its usage procedure is as follows:

[0078] 1. Preoperative planning and osteotomy. An osteotomy is performed at the normal bone at one end of the bone defect (i.e., the cut point 41), and the bone is removed... Figure 16 The proximal bone segment 38, free bone segment 39, and distal bone segment 40 are shown, preserving the blood supply and soft tissue attachment of the proximal bone segment 38 and free bone segment 39. The displacement distance is calculated based on the defect length (usually 1 mm per day), and the displacement direction is along the long axis of the bone, towards the bone defect 42, as shown in the reference. Figure 17 The free bone segment 39 is about to move towards the distal bone segment 40.

[0079] 2. Intraoperative installation.

[0080] 2.1 Bone screw implantation: Refer to Figure 16 and Figure 17 Multiple bone screws were implanted into the proximal bone segment 38 and distal bone segment 40 on both sides of the bone defect. These bone screws penetrated the skin, with their anterior ends drilling into the normal bone, and their posterior ends were clamped and fixed by the first clamp 2 and the third clamp 4. Multiple bone screws were implanted into the free bone segment 39, with their anterior ends drilling into the free bone segment 39, and their posterior ends were clamped and fixed by the second clamp 3.

[0081] 2.2 The track 1 is assembled with the first clamping block 2, the second clamping block 3, and the third clamping block 4. The track 1 is placed parallel to the outside of the limb. The first clamping block 2, the second clamping block 3, and the third clamping block 4 are installed in the dovetail groove of the track 1. The second clamping block 3 is provided with a first connecting post 6, and the third clamping block 4 is provided with a second connecting post 7. The first connecting post 6 and the second connecting post 7 are provided with adjustment devices and electric drive devices.

[0082] 3. Postoperative relocation stage.

[0083] The drive motor 9 pushes the first adjusting sleeve 25 by rotating the adjusting nut 26, compresses the first spring 24, and applies a thrust to the first scale sleeve 23. It is blocked by the second connecting post 7, which applies a reaction force to the first scale sleeve 23, the first spring 24, the first adjusting sleeve 25, and the adjusting nut 26. This, in turn, drives the threaded rod 8, the blocking nut 28, the first connecting post 6, the second clamping block 3, the clamping block fixing screw 16, and the free bone segment 39 to move towards the third clamping block 4, thereby realizing the non-manual movement of the free bone segment 39.

[0084] 4. Bone healing and removal. After relocation, the support device is fixed until the new bone mineralizes, and removed after X-ray or CT confirms bone healing.

[0085] Example 2:

[0086] Reference Figure 4This embodiment provides a novel track-type bone transport device. Unlike embodiment 1, the adjustment component of this embodiment includes a first anti-jamming sleeve 29, a first spring 24, a first adjustment sleeve 25, and an adjustment nut 26, which are sequentially fitted onto the threaded rod 8.

[0087] The first anti-jamming sleeve 29 has a first pipe section and a second pipe section with a diameter larger than the first pipe section. The connection between the first pipe section and the second pipe section forms a second step. The first pipe section is located in the circular hole provided on the second connecting post 7 for installing the threaded rod 8. The second pipe section is sleeved on the outside of the first adjusting sleeve 25 and is slidably connected to the first adjusting sleeve 25. One end of the first adjusting sleeve 25 is open, and the other end extends radially inward to form a first step. One end of the first spring 24 abuts against the inner wall surface of the second step of the first anti-jamming sleeve 29, and the other end abuts against the inner wall surface of the first step of the first adjusting sleeve 25. The inner hole of the adjusting nut 26 is threadedly connected to the threaded rod 8. The outer circumferential surface of the adjusting nut 26 is provided with a first meshing tooth. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the first meshing tooth on the adjusting nut 26 to drive the adjusting nut 26 to abut against the outer wall surface of the first step.

[0088] In this embodiment, the first anti-jamming sleeve 29 slides to support the threaded rod 8, which is used to prevent the second connecting post 7 from jamming onto the threaded rod 8.

[0089] The remaining parts that are the same as in Example 1 will not be repeated here.

[0090] Example 3:

[0091] Reference Figure 5 This embodiment provides another novel track-type bone transport device. Unlike embodiment 1, the adjustment component of this embodiment includes a first anti-jamming sleeve 29, a first spring 24, a first adjustment sleeve 25, and an adjustment screw sleeve 30, which are sequentially fitted onto the threaded rod 8.

[0092] The first anti-jamming sleeve 29 has a first pipe section and a second pipe section with a diameter larger than the first pipe section. The connection between the first pipe section and the second pipe section forms a second step. The first pipe section is located inside a circular hole on the second connecting post 7 for installing the threaded rod 8. The second pipe section is sleeved on the outside of the first adjusting sleeve 25 and is slidably connected to the first adjusting sleeve 25. One end of the first adjusting sleeve 25 is open, and the other end extends radially inward to form a first step. One end of the first spring 24 abuts against the inner wall surface of the second step of the first anti-jamming sleeve 29, and the other end abuts against the first step of the first adjusting sleeve 25. On the inner wall of the step, an adjusting screw sleeve 30 is inserted into the round hole of the first anti-jamming sleeve 29, the first spring 24 and the first adjusting sleeve 25. The inner hole of the adjusting screw sleeve 30 is threadedly connected to the threaded rod 8. The end of the adjusting screw sleeve 30 away from the second connecting post 7 extends radially outward to form a third step. The outer circumference of the third step is provided with a second meshing tooth. A drive gear 27 is provided on the shaft of the drive motor 9. The drive gear 27 meshes with the second meshing tooth on the adjusting screw sleeve 30 to drive the third step on the adjusting screw sleeve 30 to abut against the end face of the first adjusting sleeve 25.

[0093] The working process of the novel track-type bone transport device in this embodiment is as follows: The drive motor 9 drives the adjusting screw sleeve 30 to rotate through the drive gear 27, which causes the adjusting screw sleeve 30 and the threaded rod 8 to undergo relative displacement in the axial direction. As a result, the threaded rod 8 drives the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby realizing the non-manual transport of the free bone segment 39. At the same time, the third step on the adjusting screw sleeve 30 abuts against the first adjusting sleeve 25 and transmits pressure sequentially to the first spring 24, the first anti-jamming sleeve 29, and the second connecting post 7.

[0094] The remaining parts that are the same as in Example 1 will not be repeated here.

[0095] Example 4:

[0096] See Figure 6 This embodiment provides another novel track-type bone transport device. Unlike embodiment 1, the adjustment component of this embodiment includes a first anti-jamming sleeve 29, a first spring 24, and a second adjustment sleeve 31, which are sequentially fitted onto the threaded rod 8.

[0097] The first anti-jamming sleeve 29 has a first pipe section and a second pipe section with a diameter larger than the first pipe section. The connection between the first pipe section and the second pipe section forms a second step. The first pipe section is located in the round hole provided on the second connecting post 7 for installing the threaded rod 8. The second pipe section is sleeved on the outside of the second adjusting sleeve 31 and is slidably connected to the second adjusting sleeve 31. One end of the second adjusting sleeve 31 is open, and the other end extends radially inward to form a fourth step. The inner hole of the fourth step is threadedly connected to the threaded rod 8. One end of the first spring 24 abuts against the inner wall surface of the second step of the first anti-jamming sleeve 29, and the other end abuts against the inner wall surface of the fourth step of the second adjusting sleeve 31. A third meshing tooth is provided on the outer circumference surface of the second adjusting sleeve 31. A drive gear 27 is provided on the rotating shaft of the drive motor 9. The drive gear 27 meshes with the third meshing tooth on the second adjusting sleeve 31.

[0098] The working process of the novel track-type bone transport device in this embodiment is as follows: The drive motor 9 drives the second adjusting sleeve 31 to rotate through the drive gear 27, which causes the second adjusting sleeve 31 and the threaded rod 8 to undergo relative displacement in the axial direction. As a result, the threaded rod 8 drives the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby realizing the non-manual transport of the free bone segment 39. At the same time, the second adjusting sleeve 31 transmits pressure sequentially to the first spring 24, the first anti-jamming sleeve 29, and the second connecting post 7.

[0099] The rest of the same as in Example 1 will not be repeated here.

[0100] Example 5:

[0101] See Figure 7 This embodiment provides another novel track-type bone transport device. Unlike embodiment 1, the fixing components of this embodiment include a blocking nut 28, a third adjusting sleeve 34, a second spring 35, and a second scale sleeve 36, which are sequentially fitted onto the threaded rod 8.

[0102] One end of the third adjusting sleeve 34 is open, and the other end extends radially inward to form a sixth step. The second scale sleeve 36 is disposed inside the open end of the third adjusting sleeve 34. The outer wall of the third adjusting sleeve 34 and the second scale sleeve 36 are slidably connected. One end of the second spring 35 abuts against one end of the second scale sleeve 36, and the other end abuts against the inner wall surface of the sixth step of the third adjusting sleeve 34. The blocking nut 28 abuts against the outer wall surface of the sixth step of the third adjusting sleeve 34.

[0103] The remaining parts that are the same as in Example 1 will not be repeated here.

[0104] Example 6:

[0105] See Figure 8This embodiment provides another novel track-type bone transport device. Unlike embodiment 5, this novel track-type bone transport device further includes a fourth clamping block 37. The fourth clamping block 37 is located on the side of the third clamping block 4 opposite to the second clamping block 3 and is slidably mounted on the track 1. It should be noted that the specific structure of the fourth clamping block 37 is the same as that of the first clamping block 2, and will not be described again here.

[0106] The first clamping block 2 and the fourth clamping block 37 are used to fix the two ends of the defective bone, respectively, while the second clamping block 3 and the third clamping block 4 are used to fix the free bone segments 39. During operation, the electric drive device provides power to the adjustment device, which then moves the second clamping block 3 and the third clamping block 4 to move the two free bone segments 39. The two free bone segments 39 approach each other, achieving traction osteogenesis.

[0107] The remaining parts that are the same as in Example 5 will not be repeated here.

[0108] Example 7:

[0109] See Figure 9 This embodiment provides another novel track-type bone transport device. Unlike embodiment 1, the fixing component in this embodiment is a pin 32 disposed on the threaded rod 8, and the axial direction of the pin 32 is perpendicular to the axial direction of the threaded rod 8.

[0110] Furthermore, the threaded rod 8 is provided with a pin hole, and a pin 32 is provided in the pin hole.

[0111] The remaining parts that are the same as in Example 1 will not be repeated here.

[0112] Example 8:

[0113] See Figure 10 This embodiment provides another novel track-type bone transport device. Unlike embodiment 1, the fixing component in this embodiment is a fifth step 33 disposed on the threaded rod 8, which is integrated with the threaded rod 8.

[0114] The remaining parts that are the same as in Example 1 will not be repeated here.

[0115] Example 9:

[0116] See Figure 12 This embodiment provides another novel track-type bone transport device. Unlike embodiment 3, the adjustment component of this embodiment includes a first spring 24 and an adjustment sleeve 30 sequentially mounted on the threaded rod 8.

[0117] The inner hole of the adjusting screw sleeve 30 is threadedly connected to the threaded rod 8. The end of the adjusting screw sleeve 30 away from the second connecting post 7 extends radially outward to form a third step. One end of the first spring 24 abuts against the side wall of the second connecting post 7, and the other end abuts against the third step. The outer circumferential surface of the third step is provided with a second meshing tooth. The shaft of the drive motor 9 is provided with a drive gear 27, which meshes with the second meshing tooth on the adjusting screw sleeve 30 to drive the third step on the adjusting screw sleeve 30 to abut against the first spring 24.

[0118] The novel track-type bone transport device of this embodiment operates as follows: the drive motor 9 drives the adjusting sleeve 30 to rotate via the drive gear 27, causing a relative displacement between the adjusting sleeve 30 and the threaded rod 8 in the axial direction. This causes the threaded rod 8 to drive the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby achieving non-manual transport of the free bone segment 39. Simultaneously, the third step on the adjusting sleeve 30 transmits pressure to the first spring 24 and the second connecting post 7.

[0119] The remaining parts that are the same as in Example 3 will not be repeated here.

[0120] Example 10:

[0121] See Figure 13 This embodiment provides another novel track-type bone transport device. The difference between this embodiment and embodiment 3 is that the adjustment component of this embodiment includes a second anti-jamming sleeve 50 and an adjustment screw sleeve 30 that are sequentially fitted onto the threaded rod 8.

[0122] The second anti-jamming sleeve 50 has a first shaft section and a second shaft section with an outer diameter larger than the first shaft section. The connection between the first shaft section and the second shaft section forms a seventh step. The first shaft section is located in the round hole provided on the second connecting post 7 for installing the threaded rod 8. The round hole inside the second anti-jamming sleeve 50 is through which an adjusting screw sleeve 30 passes. The inner hole of the adjusting screw sleeve 30 is threadedly connected to the threaded rod 8. The end of the adjusting screw sleeve 30 away from the second connecting post 7 extends radially outward to form a third step. The outer circumferential surface of the third step is provided with a second meshing tooth. The rotating shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the second meshing tooth on the adjusting screw sleeve 30 to drive the third step on the adjusting screw sleeve 30 to abut against the end face of the second anti-jamming sleeve 50. The seventh step of the second anti-jamming sleeve 50 abuts against the side wall of the second connecting post 7.

[0123] The working process of the novel track-type bone transport device in this embodiment is as follows: The drive motor 9 drives the adjusting screw sleeve 30 to rotate through the drive gear 27, which causes the adjusting screw sleeve 30 and the threaded rod 8 to undergo relative displacement in the axial direction. As a result, the threaded rod 8 drives the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby realizing the non-manual transport of the free bone segment 39. At the same time, the third step on the adjusting screw sleeve 30 abuts against the adjusting sleeve 50 and sequentially transmits pressure to the second anti-jamming sleeve 50 and the second connecting post 7.

[0124] The remaining parts that are the same as in Example 3 will not be repeated here.

[0125] Example 11:

[0126] See Figure 14 This embodiment provides another novel track-type bone transport device. Unlike embodiment 3, the adjustment component of this embodiment includes a second anti-jamming sleeve 50, a first spring 24, and an adjustment screw sleeve 30, which are sequentially fitted onto the threaded rod 8.

[0127] The second anti-jamming sleeve 50 has a first shaft section and a second shaft section with an outer diameter larger than the first shaft section. The connection between the first shaft section and the second shaft section forms a seventh step. The first shaft section is located in the round hole provided on the second connecting post 7 for installing the threaded rod 8. The round hole inside the second anti-jamming sleeve 50 is through which an adjusting screw sleeve 30 passes. The inner hole of the adjusting screw sleeve 30 is threadedly connected to the threaded rod 8. The end of the adjusting screw sleeve 30 away from the second connecting post 7 extends radially outward to form a third step. One end of the first spring 24 abuts against the end face of the second anti-jamming sleeve 50, and the other end abuts against the inner side wall of the third step of the adjusting screw sleeve 30. The outer circumferential surface of the third step is provided with a second meshing tooth. The rotating shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the second meshing tooth on the adjusting screw sleeve 30 to drive the third step on the adjusting screw sleeve 30 to abut against the first spring 24.

[0128] The working process of the novel track-type bone transport device in this embodiment is as follows: The drive motor 9 drives the adjusting sleeve 30 to rotate through the drive gear 27, which causes the adjusting sleeve 30 and the threaded rod 8 to undergo relative displacement in the axial direction. As a result, the threaded rod 8 drives the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby realizing the non-manual transport of the free bone segment 39. At the same time, the third step on the adjusting sleeve 30 abuts against the first spring 24 and transmits pressure to the first spring 24, the second anti-jamming sleeve 50 and the second connecting post 7 in sequence.

[0129] The remaining parts that are the same as in Example 3 will not be repeated here.

[0130] Example 12:

[0131] See Figure 15 This embodiment provides another novel track-type bone transport device. The difference between this embodiment and embodiment 3 is that the adjustment component in this embodiment is an adjustment screw sleeve 30.

[0132] The inner hole of the adjusting screw sleeve 30 is threadedly connected to the threaded rod 8. One end of the adjusting screw sleeve 30 is located in the circular hole for installing the threaded rod 8 on the second connecting post 7. The other end of the adjusting screw sleeve 30 extends radially outward to form a third step. The outer circumferential surface of the third step is provided with a second meshing tooth. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the second meshing tooth on the adjusting screw sleeve 30 to drive the third step on the adjusting screw sleeve 30 to abut against the second connecting post 7.

[0133] The novel track-type bone transport device of this embodiment operates as follows: the drive motor 9 drives the adjusting sleeve 30 to rotate via the drive gear 27, causing a relative displacement between the adjusting sleeve 30 and the threaded rod 8 in the axial direction. This causes the threaded rod 8 to drive the blocking nut 28 to abut against the first connecting post 6, and drives the first connecting post 6 and the second clamping block 3 to approach the third clamping block 4, thereby achieving non-manual transport of the free bone segment 39. Simultaneously, the third step on the adjusting sleeve 30 abuts against the second connecting post 7, transmitting pressure to the second connecting post 7.

[0134] The remaining parts that are the same as in Example 3 will not be repeated here.
