Description

Technical Field

[0001] This invention relates to the field of bone treatment technology, and more specifically to a novel intelligent plate and screw internal fixation device and method. Background Technology

[0002] Traditional plate and screw devices are designed based on the skeletal characteristics of most people. However, due to individual differences in human bones, especially differences in bone shape, fracture type and bone structure, the plate often cannot fit the fracture site accurately, resulting in unsatisfactory fixation.

[0003] In response, with the development of 3D printing technology, personalized internal fixation devices for fractures have gradually become a research hotspot. Using a patient's CT scan data, plates or supports customized to the individual's bone shape can be designed. This personalized design can improve the fit between the plate and the bone, reducing postoperative complications. However, this method is mainly applied to relatively simple fracture types. For complex fractures (such as bone fragments, fractures near joints, etc.), 3D-printed plates still struggle to provide sufficient dynamic stability and adaptability, and face high costs and manufacturing challenges in practical applications, thus requiring further improvement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a novel intelligent steel plate screw internal fixing device and method.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The new intelligent steel plate screw internal fixing device includes: A connecting steel plate, comprising a straight plate and an irregular plate, wherein the connecting steel plate has at least two screw holes along its length direction, and the screw holes have convex and concave textures in their circumferential direction; the two connecting steel plates fit together through the convex and concave textures to restrict relative rotation. A connecting screw, comprising a locking screw and a pull screw, wherein the locking screw is used to connect a screw hole and a bone structure respectively, the locking screw has a through pull hole along the axis, the end of the pull screw passes through the pull hole and has a pull thread, the pull thread is used to connect to the bone structure, the pull hole has an annular pressure surface, and the pull screw includes a screw head, the screw head being used to abut against the pressure surface to apply pressure; The support member has a connecting hole between adjacent screw holes, and a connecting part on the support member is connected to the connecting hole. The support member is made of a biodegradable material.

[0006] As a further improvement of the present invention, the locking screw includes a head portion and a shank portion. The shank portion includes two symmetrically arranged arc-shaped fixing segments. One end of each of the two fixing segments is connected to the head portion and is provided with a limiting structure. The limiting structure is used to restrict the two fixing segments to move only in the direction of approaching / moving away from each other. Both ends of each fixing segment form inclined force-bearing surfaces. The force-bearing surfaces are arc-shaped and arranged circumferentially along the axis of the fixing segments. The two force-bearing surfaces are joined together to form a ring structure. The tension screw forms a force-applying surface corresponding to the force-bearing surface. The tension screw moves along the tension hole, causing the force-applying surface to contact the force-receiving surface and apply a force perpendicular to the axis of the locking screw to the fixed section, thereby causing the two fixed sections to separate from each other.

[0007] As a further improvement of the present invention, the ends of the two fixed sections are provided with limiting blocks, the nail rod is provided with a slot corresponding to the limiting block and is engaged with the limiting block, the inner diameters of the two force-bearing surfaces are different, and the inner diameter of the force-bearing surface corresponding to the end of the fixed section away from the nail head is larger than the inner diameter of the force-bearing surface corresponding to the other end.

[0008] As a further improvement of the present invention, the nail rod portion is provided with anti-slip texture along the length direction. The anti-slip texture is used to abut against the bone structure after the fixed segment moves to limit the movement of the fixed segment along the axial direction of the nail rod portion.

[0009] As a further improvement of the present invention, the locking screw is provided with a pressure ring on the pressure surface, the pressure ring is used to abut the end of the tension screw, the pressure ring is made of a biodegradable material and the pressure of the tension screw on the pressure surface is adjusted by degradation.

[0010] As a further improvement of the present invention, it also includes a sensing module, which is connected to the connecting steel plate. The sensing module forms a sensing point on one side of the steel plate. The support is made of transparent material and has a plurality of detection points inside. The plurality of detection points are staggered along the sensing direction of the sensing point. The sensing point is used to sense the detection point to determine the degradation status of the support.

[0011] As a further improvement of the present invention, a connecting unit is provided between adjacent connecting steel plates, the connecting unit being used to connect two screw holes to keep the two connecting steel plates relatively fixed.

[0012] As a further improvement of the present invention, the connecting unit includes a sleeve and a locking rod. The sleeve passes through the two screw holes respectively. One end of the sleeve is formed into a mounting hole. One end of the locking rod extends into the mounting hole and is provided with a locking block. The other end forms a fixing surface. The sleeve is provided with a locking bar in the mounting hole. One end of the locking bar is used to abut against the locking block to restrict the movement of the locking block relative to the axis of the mounting hole.

[0013] As a further improvement of the present invention, it also includes a sensor unit, which includes a detection optical fiber and a mounting base connected to one side of the connecting steel plate. The mounting base is provided with a communication module and a signal receiving module. The detection optical fiber is built into the connecting steel plate. One end of the detection optical fiber forms an identification point corresponding to one side of the steel plate, and the other end is connected to the signal receiving module. The communication module is connected to the signal receiving module and is used to transmit signals to an external terminal.

[0014] A novel intelligent steel plate screw internal fixing method, including the aforementioned novel intelligent steel plate screw internal fixing device, includes the following steps: S1. Perform a CT scan on the patient's fracture area to obtain fracture data and estimate the patient's recovery based on the fracture data; S2. Based on the patient's fracture data, the data is pieced together to form the patient's original bone data, and the bone fragments are marked. S3. Based on the patient's original bone data, the straight plate and the different plate are spliced ​​together so that the screw holes of the bone fragments correspond. At the same time, the support parts are 3D printed according to the defect area. S4. Install the spliced ​​connecting steel plates and supporting components onto the human body; S5. When installing the connecting steel plate, select a pressure ring of appropriate density based on the patient's recovery assessment, and control the pressure applied to the pressure ring by the tension screw.

[0015] The beneficial effects of this invention are: 1. The internal fixation system is achieved by using modular connecting steel plates and connecting screws, which can be spliced ​​and dynamically adjusted. The shape and size of the internal fixation can be flexibly adjusted according to different fracture conditions, so as to adapt to various fracture types, especially complex or irregular fractures, and provide more precise fixation force for the fracture site. 2. The locking screw and the bone structure are locked by the opening and closing of the two fixed sections. On the one hand, this can improve the alignment of the tension screw with the drilled hole in the bone structure during the insertion process, and on the other hand, it can achieve the alignment between the broken bones, thereby making the connection between the connecting plate and the bone structure more stable. 3. By combining sensing points and detection points, the degradation of the support component can be detected, thereby enabling real-time monitoring of the patient's bone healing status in conjunction with the sensor unit; 4. The sleeve and locking rod can maintain the relative limit and lock between the two connecting steel plates during the operation. At the same time, the locking block and locking bar can achieve quick fixation and are easy and simple to use. Attached Figure Description

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0019] Reference Figure 1-4 A novel intelligent steel plate screw internal fixing device includes: a connecting steel plate 1, the connecting steel plate 1 including a straight plate 2 and a non-straight plate 3, the connecting steel plate 1 having at least two screw holes 4 along its length, the screw holes 4 having concave and convex textures 5 around their circumference, and the two connecting steel plates 1 fitting together through the concave and convex textures 5 to restrict relative rotation.

[0020] Specifically, the different plate 3 includes arc-shaped plates with angles of 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees and 150 degrees. The different plate 3 also includes Y-shaped plates and T-shaped plates.

[0021] The use of various types of different plates can significantly improve the splicing pattern and different fracture conditions and angles, thereby providing sufficient fixation force for complex fractures (such as bone fragments, irregular fractures, fractures near joints, etc.), ensuring the stability of bone fragments during the healing process, and reducing the risk of fracture recurrence.

[0022] Meanwhile, the texture 5 can significantly improve the connection stability between adjacent connecting steel plates 1, so as to avoid displacement during the activity and cause poor bone healing.

[0023] It also includes a connecting screw 6, which includes a locking screw 7 and a tension screw 8. The locking screw 7 is used to connect the screw hole 4 and the bone structure respectively. The locking screw 7 has a through tension hole 9 along the axis. The end of the tension screw 8 passes through the tension hole 9 and has a tension thread 10. The tension thread 10 is used to connect the bone structure. The tension hole 9 has an annular pressure surface 11. The tension screw 8 includes a screw head 12, which is used to abut against the pressure surface 11 to apply pressure.

[0024] Furthermore, the surface of the tension thread 10 is coated with an antibacterial coating.

[0025] The application of an antibacterial coating can further reduce the incidence of postoperative infections.

[0026] It also includes a support member 13, a connecting hole 14 between adjacent screw holes 4, a connecting part on the support member 13 and connected to the connecting hole 14, and the support member 13 is made of a biodegradable material.

[0027] Specifically, the support component 13 is 3D printed to fit the specific defective area, ensuring maximum fit.

[0028] Preferably, the locking screw 7 includes a head portion 15 and a shank portion 16. The shank portion 16 includes two symmetrically arranged arc-shaped fixing segments 17. One end of each fixing segment 17 is connected to the head portion 15 and is provided with a limiting structure. The limiting structure is used to restrict the two fixing segments 17 to move only in the direction of approaching / moving away from each other. Both ends of the fixing segments 17 form inclined force-bearing surfaces 18. The force-bearing surfaces 18 are arc-shaped and arranged circumferentially along the axis of the fixing segments 17. The two force-bearing surfaces 18 are joined together to form a ring structure. The tension screw 8 forms a force-applying surface 19 corresponding to the force-bearing surface 18.

[0029] In the initial state, the two fixing segments 17 are attached to each other to facilitate access to the bone structure. During use, the nail rod 16 is inserted into the drill hole, and the tension screw 8 is further inserted along the tension hole 9, so that the tension thread 10 at the front end of the tension screw 8 can be drilled into the drill hole of another bone structure to complete the force application to the bone structure. At the same time, as the tension screw 8 moves along the tension hole 9, it causes the force application surface 19 to abut against the force receiving surface 18 and applies a force perpendicular to the axis of the locking screw 7 to the fixing segment 17, so that the two fixing segments 17 separate from each other, thereby making the two fixing segments 17 abut against the drill hole to complete the fixation. Thus, the positioning effect of the broken bone is achieved through the two fixing segments 17, which greatly improves the stability between the broken bone and the connecting steel plate 1, and also greatly improves the relative position fixation between the broken bones.

[0030] Preferably, the ends of the two fixed sections 17 are provided with limiting blocks 20, and the nail rod part 16 is provided with a slot 21 corresponding to the limiting block 20 and is engaged with the limiting block 20. The inner diameters of the two force-bearing surfaces 18 are different, and the inner diameter of the force-bearing surface 18 corresponding to the end of the fixed section 17 away from the nail head part 15 is larger than the inner diameter of the force-bearing surface 18 corresponding to the other end.

[0031] The limiting block 20 is fixed in position within the slot 21 by friction, and the setting of the inner diameter of the force-bearing surface 18 ensures that the tension screw 8 can pass through, making the overall structure simpler and more reliable.

[0032] Preferably, the nail rod portion 16 is provided with anti-slip texture 22 along its length direction. The anti-slip texture 22 is used to abut against the bone structure after the fixed segment 17 moves, so as to restrict the movement of the fixed segment 17 along the axial direction of the nail rod portion 16.

[0033] The anti-slip texture 22 can further improve the stability of the nail rod 16 after it moves and contacts the inner wall of the drill hole, and prevent the locking screw 7 from shifting due to the force applied by the tension screw 8, so as to ensure that the nail rod 16 applies force evenly to the broken bone and avoid local stress concentration.

[0034] The anti-slip texture 22 is coated with a hydroxyapatite coating.

[0035] The hydroxyapatite coating improves biocompatibility and degrades over time, reducing stress on bones.

[0036] Preferably, the locking screw 7 is provided with a pressure ring 23 corresponding to the pressure surface 11. The pressure ring 23 is used to abut the end of the tension screw 8. The pressure ring 23 is made of a biodegradable material and the pressure of the tension screw 8 on the pressure surface is adjusted by degradation.

[0037] Specifically, in this embodiment, the support member 13 and the pressure ring 23 are both made of polylactic acid, polycaprolactone, etc.

[0038] Among them, the appropriate density of the pressure ring 23 can be selected according to the patient's specific fracture condition, thereby regulating the degradation rate of the pressure ring 23.

[0039] By setting the pressure ring 23, the tension of the tension screw 8 on the fractured bone can be adjusted by the degradation of the pressure ring 23. As the bone recovers, the tension can be continuously released, thereby avoiding poor healing caused by excessive pressure and greatly improving the bone healing effect.

[0040] Preferably, it also includes a sensing module 24, which is connected to the connecting steel plate 1. The sensing module 24 forms a sensing point 25 on one side of the steel plate. The support member 13 is made of transparent material and has a number of detection points 26 inside. The number of detection points 26 are staggered along the sensing direction of the sensing point 25. The sensing point 25 is used to sense the detection point 26 to determine the degradation status of the support member 13.

[0041] Specifically, in this embodiment, the detection point 26 is a recognition area of ​​different colors, and the sensing module 24 is specifically a fiber optic sensor. The fiber optic sensor obtains different current signals based on optical recognition of different colors to determine the state of the detection point 26. That is, when the detection point 26 disappears, it can be determined that the support member 13 in that area has degraded, and thus it can be used as a reference for bone healing to determine the bone healing status.

[0042] Among them, the detection points of different colors are formed into block-shaped areas by using the same material of different colors during the 3D printing process.

[0043] Preferably, a connecting unit 27 is provided between adjacent connecting steel plates 1. The connecting unit 27 is used to connect two screw holes 4 to keep the two connecting steel plates 1 relatively fixed.

[0044] Preferably, the connecting unit 27 includes a sleeve 28 and a locking rod 29. The sleeve 28 passes through two screw holes 4 respectively. One end of the sleeve 28 is formed into a mounting hole 30. One end of the locking rod 29 extends into the mounting hole 30 and is provided with a locking block 31. The other end forms a fixing surface. The sleeve 28 is provided with a locking bar 32 in the mounting hole 30. The locking bar 32 is made of elastic material. One end of the locking bar 32 is used to abut against the locking block 31 to restrict the movement of the locking block 31 relative to the axis of the mounting hole 30.

[0045] In the initial state, the screw holes 4 of the two connecting steel plates 1 correspond to each other. One end of the sleeve 28 passes through the two screw holes 4 and is connected to the locking rod 29. At this time, the two connecting steel plates 1 can rotate relative to each other. The angle between the two connecting steel plates 1 can be adjusted according to the specific situation during the operation. After the adjustment is completed, by pressing the locking rod 29, the locking block 31 is completely passed through the locking bar 32, so that the locking bar 32 abuts against the locking block 31 to complete the complete fixation of the locking rod 29 and the sleeve 28. At the same time, the two connecting steel plates 1 are restricted from rotation by the concave and convex texture 5 to complete the complete fixation of the two connecting steel plates 1.

[0046] Preferably, it also includes a sensor unit 33, which includes a detection optical fiber and a mounting base 34 connected to one side of the connecting steel plate 1. The sensing module 24 is also disposed in the mounting base 34. The mounting base 34 is provided with a communication module 35 and a signal receiving module 36. The detection optical fiber is built into the connecting steel plate 1. One end of the detection optical fiber forms an identification point corresponding to one side of the steel plate, and the other end is connected to the signal receiving module 36. The communication module 35 is connected to the signal receiving module 36 and is used to transmit signals to an external terminal.

[0047] The fiber optic module enables real-time monitoring of bone healing, allowing for timely adjustments to the connecting plate 1 and connecting screws 6 during treatment to ensure optimal fracture recovery.

[0048] Reference Figure 5 A novel intelligent steel plate screw internal fixing method, including the aforementioned novel intelligent steel plate screw internal fixing device, includes the following steps: S1. Perform a CT scan on the patient's fracture area to obtain the patient's fracture data, and obtain the patient's recovery estimate based on the fracture data. In this embodiment, a patient database is established, and the obtained patient fracture data is used to obtain the patient's recovery estimate. The patient's recovery estimate specifically includes the recovery time and the recovery status at different time periods.

[0049] S2. Based on the patient's fracture data, the fragments are pieced together to form the patient's original bone data, and the fragments are marked to facilitate the subsequent arrangement, connection and fixation of the fragments, so as to maintain the consistency between the patient's bone morphology after healing and the original bone morphology data as much as possible.

[0050] S3. Based on the patient's original bone data, the straight plate 2 and the different plate 3 are spliced ​​together, and the position of the straight plate 2 or the different plate 3 is adjusted so that the screw hole 4 corresponds to the position of the bone fragment. At the same time, the support part 13 is 3D printed according to the defect area.

[0051] S4. Install the spliced ​​connecting steel plate 1 and support component 13 onto the human body.

[0052] S5. When installing the connecting steel plate 1, select a pressure ring 23 of appropriate density according to the patient's recovery estimate, and control the pressure applied to the pressure ring 23 by the tension screw 8. This allows the pressure ring 23 to continuously degrade during the patient's recovery process to release the tension force of the tension screw 8 on the fractured bone, thereby achieving a gradual automatic pressure release effect to improve bone healing.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
