Description

Technical Field

[0001] This invention relates to the field of orthopedic medical device technology, and in particular to an automated track-type bone transport device. Background Technology

[0002] In the field of orthopedic treatment, bone transport devices are widely used as a key medical instrument in the treatment of bone defects, nonunion, bone lengthening, limb length discrepancies, and post-traumatic bone defects. Based on the Ilizarov technique, bone transport devices stimulate new bone formation and soft tissue regeneration by slowly pulling on the bone and surrounding tissues, providing patients with an effective treatment method.

[0003] Chinese patent document CN111134812A discloses a single-bar bone transport device. (See also...) Figure 12 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 43 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.

[0004] In addition, see Figure 17 and Figure 18The existing bone track-type bone transport device includes a track 1, clamp 1 2, clamp 2 3, and clamp 3 4. A set of bone screws mounted on clamp 1 2 is used to fix the proximal bone segment 38, a set of bone screws on clamp 2 3 is used to fix the free bone segment 39, and a set of bone screws on clamp 3 4 is used to fix the distal bone segment 40. In use, the distance between the clamps is manually adjusted to adapt to different treatment needs. However, manual adjustment has drawbacks such as insufficient precision, inconvenience, complexity, tediousness, and increased workload. Especially when fine adjustments are required, manual adjustment cannot achieve the high precision required, affecting the quality and rate of new bone tissue formation. Furthermore, frequent manual adjustments increase the workload of doctors or patients, and improper operation may lead to equipment loosening or other mechanical failures.

[0005] Therefore, there is an urgent clinical need for an automated track-type bone transport device that offers high adjustment precision and ease of operation. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an automated track-type bone transport device, which solves the technical problems of existing track-type bone transport devices that rely on manual adjustment of the movement distance and adjustment frequency of the clamps, resulting in low adjustment accuracy, cumbersome operation, inconvenient operation, and increased workload of medical staff.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] This invention provides an automated track-type bone transport device, including a track, an adjustment device, a drive device, a clamping block one, a clamping block two, and a clamping block three;

The drive device moves clamping block two by driving the adjustment component. Clamping block two moves the free bone segment by driving bone screws.

[0013] Optionally, the drive unit includes a drive motor, a programmable controller, and control components;

[0014] The control component is connected to the programmable controller, which in turn is connected to the drive motor. The control component can receive execution information input by the user and send control signals to the programmable controller based on the execution information. The programmable controller can convert the control signals into control commands and control the drive motor to move according to the control commands. The drive motor is connected to the adjustment component via a transmission connection.

[0017] The rangefinder is used to detect the distance information between clamp two and / or clamp three, and feeds the distance information back to the control component. The control component determines whether the distance information is equal to the first preset value:

[0018] If so, the control component sends a control signal to the programmable controller, which then controls the drive motor to self-lock.

[0019] If not, the control component sends a control signal to the programmable controller, which then controls the drive motor to operate.

[0020] Optionally, it also includes connecting post three, connecting post four, and multiple clamping block fixing screws;

[0024] Pressure sensors are installed between the fixed component and connecting column one, between the adjusting component and connecting column two, or between any two adjacent components inside the adjusting component;

[0025] The pressure sensor can detect pressure information and feed it back to the control component. The control component then determines whether the pressure information is less than a second preset value.

[0026] If so, the control component sends a control signal to the programmable controller, which then controls the drive motor to operate normally.

Detailed Implementation

[0065] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper" and "lower" are used interchangeably with other directional terms. Figure 1 The orientation is for reference only, and is not the orientation used in actual use of the product in this patent.

[0066] Example 1:

[0067] Reference Figure 1 , Figure 2 and Figure 3 This embodiment provides an automated track-type bone transport device, including a track 1, an adjustment device, a drive device, clamping blocks 2, 3, and 4. 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 clamping blocks 2, 3, and 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 clamping block 2 is used to fix the proximal bone segment 38, a set of bone screws on clamping block 3 is used to fix the free bone segment 39, and a set of bone screws on 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, free bone segment 39, and distal bone segment 40 in the prior art, reference is made to... Figure 12 , Figure 17 and Figure 18 Therefore, it is understood that a schematic diagram of the bone screw fixation position applicable to this embodiment is no longer provided.

[0068] Clamping blocks 2, 3, and 4 are sequentially slidably mounted on track 1. Bone screws are installed on each of these blocks to fix the bone segment. A connecting post 6 is mounted on clamping block 3, and a connecting post 7 is mounted on clamping block 4. Adjustment devices are installed on both connecting posts 6 and 7. These adjustment devices connect adjacent clamping blocks 3 and 4 and apply traction force along the long axis of the bone to the free bone segment, thereby achieving traction osteogenesis.

[0069] 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.

[0070] The adjustment device includes a threaded rod 8, a fixing component, and an adjustment component. The threaded rod 8 passes through the connecting post 1 6 and the connecting post 2 7. The fixing component is provided at one end of the threaded rod 8, and the adjustment component and the driving device are connected to the adjustment component in a transmission manner at the other end. The driving device moves the clamping block 2 3 by driving the adjustment component. The clamping block 2 3 moves the free bone segment 39 by driving the bone screw.

[0071] It should be noted that the drive device serves as the power source for the regulating device, and is used to automatically and mechanically drive the regulating device.

[0072] The automated track-type bone transport device of this embodiment, due to the inclusion of the above-described structure, can achieve automated and precise transport of free bone segments 39, thereby improving the treatment effect; in addition, it is easy to operate, reducing the workload of doctors or patients.

[0073] In this embodiment, clamp 1 2 and clamp 3 4 are used to fix the two ends of the defective bone, respectively, and clamp 2 3 is used to fix the free bone segment 39.

[0075] The control component 11 is connected to the programmable controller 10, and the programmable controller 10 is connected to the drive motor 9. The control component 11 can receive execution information input by the user and send control signals to the programmable controller 10 according to the execution information. The programmable controller 10 can convert the control signals into control commands and control the drive motor 9 to move according to the control commands. The drive motor 9 is connected to the adjustment component for transmission.

[0076] Preferably, a connecting device 12 is provided on the clamping block 3 4, and a drive motor 9 is installed on the connecting device 12. The drive motor 9 is a servo motor or a stepper motor.

The graduated sleeve 23 is disposed inside the open end of the adjusting sleeve 25, and the adjusting sleeve 25 is slidably connected to the outer wall of the graduated sleeve 23. One end of the spring 24 abuts against one end of the graduated sleeve 23, and the other end abuts against the inner wall of the step of the 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 meshing tooth. The shaft of the drive motor 9 is provided with a drive gear 27, which meshes with the meshing tooth on the adjusting nut 26 to drive the adjusting nut 26 to abut against the outer wall of the step.

[0078] Preferably, the fixing component in this embodiment is a blocking nut 28, which is threadedly connected to the threaded rod 8.

[0079] Preferably, in this embodiment, a rangefinder 13 is provided on clamping blocks 2 3 and 3 4, and the rangefinder 13 is connected to the control component 11. The rangefinder 13 is used to detect the distance information between clamping blocks 2 3 and 3 4, and feeds the distance information back to the control component 11. The control component 11 determines whether the distance information is equal to a first preset value: if yes, the control component 11 sends a control signal to the programming controller 10, and the programming controller 10 controls the drive motor 9 to self-lock; if no, the control component 11 sends a control signal to the programming controller 10, and the programming controller 10 controls the drive motor 9 to operate.

[0080] It should be noted that the function of the rangefinder 13 is to detect the distance information between clamping block 2 3 and clamping block 3 4, and feed the distance information back to the programmable controller 10, thereby forming a closed-loop control and further improving the driving accuracy.

The rangefinder 13 includes a transmitter and a receiver. One of the transmitter and receiver is set on the connecting post 14, and the other transmitter and receiver is set on the connecting post 15.

[0084] 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, and clamp block 1 2, clamp block 2 3 or clamp block 3 4 can be fixed in the track 1, restricting its movement along the length direction of the track 1.

[0085] Combination Figure 2 and Figure 4 As shown, clamping block 2 specifically includes sub-clamping block 20 and sub-clamping block 21. Sub-clamping block 21 has a T-shaped step 18 at its bottom, which is slidably positioned within a dovetail groove 17 on the track 1. Sub-clamping block 20 is positioned above sub-clamping block 21 and is detachably connected to it by bolts. The opposite sides of sub-clamping blocks 20 and 21 have grooves for fixing bone screws. Furthermore, it should be noted that the specific structures of clamping blocks 23 and 34 are the same as those of clamping block 2, and will not be described again here.

[0086] The automated track-type bone transport device of this embodiment also includes a pressure sensor 22 electrically connected to the control component 11. The pressure sensor 22 can be installed between the fixing component and the first connecting column 6, between the adjusting component and the second connecting column 7, or between any two adjacent components inside the adjusting component.

[0087] Preferably, the pressure sensor 22 in this embodiment can detect pressure information and feed it back to the control component 11. The control component 11 determines whether the pressure information is less than a second preset value: if so, the control component 11 sends a control signal to the programmable controller 10, and the programmable controller 10 controls the drive motor 9 to operate normally; if not, the control component 11 sends a control signal to the programmable controller 10, and the programmable controller 10 controls the drive motor 9 to self-lock. The purpose of setting the pressure sensor 22 is to detect the traction force applied to the free bone segment 39 by the drive device, to prevent excessive traction force from injuring human tissue, or to stop traction in time when the free bone segment 39 is moved into place.

[0088] In this embodiment, a pressure sensor 22 is provided between the inner wall of the spring 24 and the adjusting sleeve 25.

[0089] The working process of the automated 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 connecting post 6, and drives the connecting post 6 and the clamping block 3 to approach the clamping block 4, thereby realizing the automated transport of the free bone segment 39. At the same time, the adjusting nut 26 abuts against the adjusting sleeve 25, the graduated sleeve 23, the spring 24, and the connecting post 7.

[0090] The outer wall of the graduated sleeve 23 is equipped with a traction force scale for reference, which can be visually observed by the operator. The function of the 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 traction, and less prone to jamming failure of the traction device.

[0091] The automated track-type bone transport device of this embodiment 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 process is as follows:

[0092] 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 17 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 18 The free bone segment 39 is about to move towards the distal bone segment 40.

[0093] 2. Intraoperative installation.

[0094] 2.1 Bone screw implantation: Refer to Figure 17 and Figure 18 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 bone, and their posterior ends were clamped and fixed by clamp block 1 2 and clamp block 3 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 clamp block 2 3.

[0095] 2.2. The track 1 is assembled with clamping blocks 1, 2, 3, and 4. The track 1 is placed parallel to the outside of the limb. Clamping blocks 1, 2, 3, and 4 are installed in the dovetail groove of the track 1. A connecting post 1, 6 is provided on clamping block 2, and a connecting post 2, 7 is provided on clamping block 4. An adjustment device and a drive device are provided on connecting post 1, 6 and connecting post 2, 7.

[0096] 3. Postoperative relocation stage.

[0097] The control component 11 receives the execution information input by the doctor and sends control signals to the programmable controller 10 according to the execution information. The programmable controller 10 can convert the control signals into control commands and control the drive motor 9 to operate according to the control commands. The drive motor 9 pushes the adjusting sleeve 25 and compresses the spring 24 by rotating the adjusting nut 26, giving the scale sleeve 23 a thrust. It is blocked by the connecting post 7 and gives the scale sleeve 23, spring 24, adjusting sleeve 25, and adjusting nut 26 a reaction force, which in turn drives the threaded rod 8, blocking nut 28, connecting post 6, clamp 3, clamp fixing screw 16, and free bone segment 39 to move towards clamp 4, realizing the automated transfer of free bone segment 39. The rangefinder 13 detects the transfer distance of free bone segment 39, and the pressure sensor 22 displays the traction force.

[0098] 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.

[0099] Example 2:

[0100] Reference Figure 5 This embodiment provides an automated track-type bone transport device. Unlike embodiment 1, the adjustment component in this embodiment includes an anti-jamming sleeve 29, a spring 24, an adjustment sleeve 25, and an adjustment nut 26, which are sequentially mounted on the threaded rod 8.

[0101] The 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 step 2. The first pipe section is located in the round hole provided on the connecting post 7 for installing the threaded rod 8. The second pipe section is sleeved on the outside of the adjusting sleeve 25 and is slidably connected to the adjusting sleeve 25. One end of the adjusting sleeve 25 is open, and the other end extends radially inward to form a step 1. One end of the spring 24 abuts against the inner wall surface of the step 2 of the anti-jamming sleeve 29, and the other end abuts against the inner wall surface of the step 1 of the 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 meshing tooth 1. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the meshing tooth 1 on the adjusting nut 26 to drive the adjusting nut 26 to abut against the outer wall surface of the step 1.

[0102] In this embodiment, the anti-clamp sleeve 29 slides to support the threaded rod 8, which is used to prevent the connecting post 7 from getting stuck on the threaded rod 8.

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

[0104] Example 3:

[0105] Reference Figure 6 This embodiment provides another automated track-type bone transport device. Unlike embodiment 1, the adjustment component of this embodiment includes an anti-jamming sleeve 29, a spring 24, an adjustment sleeve 25, and an adjustment screw sleeve 30, which are sequentially mounted on the threaded rod 8.

[0106] The 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 step two. The first pipe section is located in the circular hole provided on the connecting post 7 for installing the threaded rod 8. The second pipe section is sleeved on the outside of the adjusting sleeve 25 and is slidably connected to the adjusting sleeve 25. One end of the adjusting sleeve 25 is open, and the other end extends radially inward to form a step one. One end of the spring 24 abuts against the inner wall surface of the step two of the anti-jamming sleeve 29, and the other end abuts against the step of the adjusting sleeve 25. On the inner wall of the first, an adjusting screw sleeve 30 is inserted into the round hole of the anti-jamming sleeve 29, the spring 24 and the adjusting sleeve 25. The inner hole of the adjusting screw sleeve 30 is threaded to the threaded rod 8. The end of the adjusting screw sleeve 30 away from the connecting column 7 extends radially outward to form a step 3. The outer circumference of the step 3 is provided with meshing teeth 2. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the meshing teeth 2 on the adjusting screw sleeve 30 to drive the step 3 on the adjusting screw sleeve 30 to abut against the end face of the adjusting sleeve 25.

[0107] 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 connecting post 6, and drives the connecting post 6 and the clamping block 3 to approach the clamping block 4, thereby realizing the automated transport of the free bone segment 39. At the same time, the step 3 on the adjusting screw sleeve 30 abuts against the adjusting sleeve 25 and transmits the pressure to the spring 24, the anti-jamming sleeve 29 and the connecting post 7 in sequence.

[0108] The remaining parts that are the same as in Example 1 will not be repeated here.

[0109] Example 4:

[0110] See Figure 7This embodiment provides another automated track-type bone transport device. Unlike embodiment 1, the adjustment component of this embodiment includes an anti-jamming sleeve 29, a spring 24, and an adjustment sleeve 31, which are sequentially mounted on the threaded rod 8.

[0111] 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 step 2. The first pipe section is located in the round hole provided on the connecting post 7 for installing the threaded rod 8. The second pipe section is sleeved on the outside of the adjusting sleeve 31 and is slidably connected to the adjusting sleeve 31. One end of the adjusting sleeve 31 is open, and the other end extends radially inward to form a step 4. The inner hole of the step 4 is threadedly connected to the threaded rod 8. One end of the spring 24 abuts against the inner wall surface of the step 2 of the anti-jamming sleeve 29, and the other end abuts against the inner wall surface of the step 4 of the adjusting sleeve 31. The outer circumferential surface of the adjusting sleeve 31 is provided with a meshing tooth 3. The shaft of the drive motor 9 is provided with a drive gear 27, which meshes with the meshing tooth 3 on the adjusting sleeve 31.

[0112] In this embodiment, a pressure sensor 22 is provided between the inner wall of the spring 24 and the adjusting sleeve 31.

[0113] 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 31 to rotate through the drive gear 27, which causes the 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 connecting post 6, and drives the connecting post 6 and the clamping block 3 to approach the clamping block 4, thereby realizing the automated transport of the free bone segment 39. At the same time, the adjusting sleeve 31 transmits pressure sequentially to the spring 24, the anti-jamming sleeve 29, and the connecting post 7.

[0114] The rest of the same as in Example 1 will not be repeated here.

[0115] Example 5:

[0116] See Figure 8 This embodiment provides another automated track-type bone transport device. Unlike embodiment 1, the fixing components of this embodiment include a blocking nut 28, an adjusting sleeve 34, a spring 35, and a scale sleeve 36, which are sequentially fitted onto the threaded rod 8.

[0117] One end of the adjusting sleeve 34 is open, and the other end extends radially inward to form step six. The scale sleeve 2 36 is set inside the open end of the adjusting sleeve 34. The adjusting sleeve 34 and the outer wall of the scale sleeve 2 36 are slidably connected. One end of the spring 2 35 abuts against one end of the scale sleeve 2 36, and the other end abuts against the inner wall surface of step six of the adjusting sleeve 34. The blocking nut 28 abuts against the outer wall surface of step six of the adjusting sleeve 34.

[0118] The remaining parts that are the same as in Example 1 will not be repeated here.

[0119] Example 6:

[0120] See Figure 9 This embodiment provides another automated track-type bone transport device. Unlike embodiment 5, this embodiment's automated track-type bone transport device further includes clamping block four 37, which is slidably mounted on track 1. It should be noted that the specific structure of clamping block four 37 is the same as that of clamping block two 2, and will not be described again here. Clamping block one 2 and clamping block four 37 are used to fix the two ends of the defective bone, while clamping blocks two 3 and three 4 are used to fix the free bone segments 39. During operation, the drive device provides power to the adjustment device, which then moves clamping blocks two 3 and three 4 to move the two free bone segments 39 closer together, achieving traction osteogenesis.

[0121] In this embodiment, the rangefinder 13 detects the distance information between clamping block 2 3 and clamping block 3 4 and feeds the distance information back to the control component 11. The control component 11 determines whether the distance information is equal to a first preset value: if yes, the control component 11 sends a control signal to the programming controller 10, and the programming controller 10 controls the drive motor 9 to self-lock; if no, the control component 11 sends a control signal to the programming controller 10, and the programming controller 10 controls the drive motor 9 to move so that clamping block 2 3 and clamping block 3 4 move to a predetermined position.

[0122] The remaining parts that are the same as in Example 5 will not be repeated here.

[0123] Example 7:

[0129] The remaining parts that are the same as in Example 1 will not be repeated here.

[0130] Example 9:

[0131] See Figure 13 This embodiment provides another automated track-type bone transport device. Unlike embodiment 3, the adjustment component of this embodiment includes a spring 24 and an adjustment sleeve 30 sequentially mounted on the threaded rod 8.

[0132] 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 connecting post 7 extends radially outward to form a step 3. One end of the spring 24 abuts against the side wall of the connecting post 7, and the other end abuts against the step 3. The outer circumferential surface of the step 3 is provided with meshing teeth 2. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the meshing teeth 2 on the adjusting screw sleeve 30 to drive the step 3 on the adjusting screw sleeve 30 to abut against the spring 24.

[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. This causes the adjusting sleeve 30 and the threaded rod 8 to undergo relative displacement in the axial direction. Consequently, the threaded rod 8 drives the blocking nut 28 to abut against the connecting post 6, and drives the connecting post 6 and the clamping block 3 to approach the clamping block 4, thereby achieving automated transport of the free bone segment 39. At the same time, the step 3 on the adjusting sleeve 30 transmits pressure to the spring 24 and the connecting post 7.

[0134] In this embodiment, a pressure sensor 22 is provided between the spring 24 and the step 3 of the adjusting screw sleeve 30.

The connection between the first shaft section and the second shaft section forms a step 7. The first shaft section is located in the round hole provided on the connecting post 2 7 for installing the threaded rod 8.

The outer circumferential surface of the step 3 is provided with a meshing tooth 2. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the meshing tooth 2 on the adjusting screw sleeve 30 to drive the step 3 on the adjusting screw sleeve 30 to abut against the end face of the anti-jamming sleeve 2 50. The step 7 of the anti-jamming sleeve 2 50 abuts against the side wall of the connecting post 2 7.

[0139] 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 connecting post 6, and drives the connecting post 6 and the clamping block 3 to approach the clamping block 4, thereby realizing the automated transport of the free bone segment 39. At the same time, the step 3 on the adjusting screw sleeve 30 abuts against the adjusting sleeve 50 and sequentially transmits pressure to the anti-jamming sleeve 50 and the connecting post 7.

The end of the adjusting screw sleeve 30 away from the connecting post 2 7 extends radially outward to form a step 3. One end of the spring 1 24 abuts against the end face of the anti-jamming sleeve 2 50, and the other end abuts against the inner side wall of the step 3 of the adjusting screw sleeve 30. The outer circumferential surface of the step 3 is provided with meshing teeth 2. The shaft of the drive motor 9 is provided with a drive gear 27. The drive gear 27 meshes with the meshing teeth 2 on the adjusting screw sleeve 30 to drive the step 3 on the adjusting screw sleeve 30 to abut against the spring 1 24.
