Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an integrated modular bio-ring reconstruction device for the acetabulum. Background Technology

[0002] Total hip replacement is a safe and effective treatment for hip joint diseases, playing an important role in the field of orthopedics. The clinical application of total hip replacement surgery is becoming increasingly widespread. Some patients require revision surgery for various reasons, such as prosthesis loosening, joint instability, and joint infection. In particular, the problem of large-scale and irregular anatomical bone defects in the acetabulum caused by osteolysis and infection after hip replacement surgery has always been a challenge in the field of orthopedics, because the reconstruction effect of the acetabular structure is directly related to the success or failure of the surgery and has a significant impact on the patient's rehabilitation and quality of life.

[0003] In related technologies, there are two main conventional methods for reconstructing acetabular defects. One is bone grafting, which involves taking bone from other parts of the patient's body or using allogeneic bone and transplanting it to the acetabular bone defect. This method attempts to repair the defect by utilizing the regenerative capacity of bone tissue. However, the availability of bone sources is limited, and it may cause additional trauma to the patient. Another common approach is to use acetabular fillers, usually single-shaped prostheses, to directly fill the acetabular bone defect. These fillers are generally prefabricated to standard specifications and are intended to integrate with the acetabular bone through physical fixation. Some methods use simple support structures to maintain the basic shape of the acetabulum, but these support structures often lack flexibility and are difficult to adjust according to the specific circumstances of different patients.

[0004] Regarding the aforementioned technologies, traditional bone grafting methods are limited by the availability of bone, and the fusion effect after bone grafting is difficult to guarantee, easily leading to problems such as bone resorption. A single-shaped acetabular filler cannot well adapt to the diverse bone defects of different patients, failing to achieve precise matching and resulting in poor reconstruction effects. Furthermore, simple support structures lack flexibility and adjustability, unable to be flexibly adjusted according to the specific location and extent of the patient's bone defect, thus failing to provide effective support and stable reconstruction for the acetabulum. Summary of the Invention

[0005] To address the problem of insufficient support and stable reconstruction of the acetabulum, this application provides an integrated modular bio-ring reconstruction device for the acetabulum.

[0006] The modular bio-ring reconstruction integrated device for the acetabulum provided in this application adopts the following technical solution: A modular bio-ring reconstruction integrated device for the acetabulum includes a combined reconstruction ring and a bio-reconstruction support. The combined reconstruction ring is embedded in the acetabular fossa and forms a metal bone trabeculae to reconstruct a complete acetabular fossa. The bioreconstruction support is connected to the combined reconstruction ring, and the bioreconstruction support is used to connect the combined reconstruction ring to the acetabulum.

[0007] By adopting the above technical solution, the combined reconstruction ring is embedded in the acetabular fossa to form a metal bone trabeculae, which can reconstruct a complete acetabular fossa. The biological reconstruction support connects the combined reconstruction ring and connects it to the acetabulum, which can enhance the reconstruction effect of the acetabulum, promote bone ingrowth and bone fusion, and help provide effective support and stable reconstruction for the acetabulum. This solves the problem of treating acetabular bone defects, improves the accuracy and safety of the operation, reduces surgical risks, shortens the operation time, and improves clinical efficacy.

[0008] In one specific implementation, the combined reconstruction ring includes a warp and weft combined reconstruction ring, which includes a central fixing ring, multiple warp supports, and multiple weft semi-rings. The central fixing ring is connected to the bottom of the acetabular fossa, and the multiple warp supports are all connected to the top of the central fixing ring. The multiple warp supports are evenly distributed around the circumference of the central fixing ring. The warp supports are arc-shaped, and the arc openings of the warp supports face one side of the axis of the central fixing ring. The multiple warp supports form a placement area that fits with the acetabular cup. The multiple weft semi-rings form a weft ring, which is located within the placement area. The weft ring is coaxially arranged with the central fixing ring and is connected to the warp supports. The bio-reconstruction support is connected to the latitude-longitude combined reconstruction ring, and the bio-reconstruction support is used to connect the latitude-longitude combined reconstruction ring to the acetabulum.

[0009] By adopting the above technical solution, the central fixing ring of the latitude-longitude combined reconstruction ring is connected to the bottom of the acetabular fossa. The latitude support of the latitude-longitude combined reconstruction ring can form a placement area that fits the acetabular cup, which is convenient for placing the acetabular cup. The structure formed by the connection of the latitude ring and the latitude support, with multiple latitude semi-rings surrounding the latitude ring and connected to the latitude support, enables the device to accurately adapt to different bone defect conditions, improve the acetabular reconstruction effect, and can be flexibly adjusted according to different bone defect conditions of patients to achieve precise adaptation. The biological reconstruction support can connect the latitude-longitude combined reconstruction ring to the acetabulum, enhance the reconstruction effect of the acetabulum, and promote bone ingrowth and bone fusion.

[0010] In one specific implementation, the top of the central fixing ring is integrally and coaxially provided with an annular slide rail, and the warp support is provided with a sliding groove adapted to the annular slide rail on the side near the annular slide rail, so that it can slide freely on the annular slide rail. When the warp support does not need to slide, the warp support is fixed to the annular slide rail.

[0011] By adopting the above technical solution, the annular slide rail and the sliding groove cooperate to allow the meridian support to slide freely on the annular slide rail. This allows the device to flexibly adjust the position and direction of the meridian support according to the different bone defects of the patients, so as to achieve precise fitting. After the position of the meridian support is adjusted, it is fixed to the annular slide rail to ensure the stability of the support structure and ensure that the entire device functions normally.

[0012] In one specific implementation, the central fixing ring has multiple arc-shaped grooves on the top of the annular slide rail, and the multiple arc-shaped grooves are evenly distributed along the circumference of the annular slide rail.

[0013] By adopting the above technical solution, on the one hand, the arc groove can play a role in accurately marking the position during clinical installation; on the other hand, after the position of the warp support is adjusted, the position of the warp support can be locked by passing the round-headed top screw through the warp support and the arc groove.

[0014] In one specific implementation, the warp support has a fixing groove for placing the weft ring on the side near the central fixing ring, and one end of the weft half-ring extends into the fixing groove and is interference-fitted with the fixing groove.

[0015] By adopting the above technical solution, a fixing groove is opened in the warp support, and one end of the weft semi-ring extends into the fixing groove and is interference-fitted, which can realize a stable connection between the weft ring and the warp support. This helps to further construct a stable warp and weft combined reconstruction ring structure, thereby better adapting to the different acetabular bone defects of different patients, improving the acetabular reconstruction effect, promoting bone ingrowth and bone fusion, and improving the accuracy and safety of the operation.

[0016] In one specific implementation, the warp support is provided with a pawl at the end away from the central fixing ring. The pawl is located on the side of the warp support close to the axis of the central fixing ring. A locking ring groove is provided on the top of the acetabular cup. The pawl cooperates with the locking ring groove to restrict the rotational freedom of the acetabular cup.

[0017] By adopting the above technical solution, the claw at the end of the warp support away from the central fixing ring cooperates with the locking ring groove at the top of the acetabular cup, which can restrict the rotational freedom of the acetabular cup, fix the position of the acetabular cup, prevent the acetabular cup from shifting, ensure the stability of the acetabular cup during use, avoid a series of problems caused by the rotation of the acetabular cup, and improve the function and service life of the hip joint.

[0018] In one specific implementation scheme, the biological reconstructive support includes a trabecular conical column, the meridian support has a support hole, the trabecular conical column is divided into a threaded section and a fixed section, the trabecular conical column passes through the support hole, the threaded section is located in the support hole, the threaded section is threadedly connected to the meridian support, and the outer wall of the fixed section is provided with a reverse tooth structure, the reverse teeth are inclined from the fixed section to the threaded section toward the axis away from the trabecular conical column; The trabecular tapered column has a porous trabecular structure.

[0019] By adopting the above technical solution, the threaded section of the trabecular tapered column is threadedly connected to the meridian support, and the reverse tooth structure of the fixation section is embedded in the cancellous bone of the acetabulum, which can prevent the biological reconstruction support from loosening and enhance the fixation effect. The porous structure of the trabecular bone can promote bone ingrowth and bone fusion.

[0020] In one specific implementation scheme, a connecting component is also included, which is a locking pin. A locking pin hole is provided through the middle of the top wall of the trabecular cone column along its central axis. The locking pin is inserted into the acetabulum after passing through the locking pin hole. The locking pin is threadedly connected to the trabecular cone column for strengthening the fixation of the trabecular cone column.

[0021] By adopting the above technical solution, the locking pin is inserted into the locking pin hole of the trabecular tapered column and extends into the acetabulum, which can strengthen the fixation of the trabecular tapered column, further ensure the stability between the various components, and improve the acetabular reconstruction effect.

[0022] In one specific implementation, the combined reconstruction ring further includes a biological reconstruction ring, which is composed of half rings, full rings, and 2 / 3 rings of different diameters. Clinically, these rings can be freely combined according to the patient's defect location and degree. The biological reconstruction ring is embedded in the acetabular fossa, and a bone implantation groove is provided on the outer wall of the biological reconstruction ring. The bone implantation groove is arranged circumferentially along the outer wall of the biological reconstruction ring for implanting bone blocks or biological materials. The biological reconstruction support fixes the biological reconstruction ring to the acetabulum.

[0023] By adopting the above technical solutions, semi-rings, full rings, and 2 / 3 rings of different diameters can be freely combined according to the location and extent of the patient's defect, which can reconstruct a complete acetabular fossa and achieve precise fitting; the outer wall of the biological reconstruction ring is provided with a circumferential bone block implantation groove for implanting bone blocks or biomaterials, which can increase the biological fixation effect of the bonding surface; the biological reconstruction support can fix the biological reconstruction ring to the acetabulum and enhance the overall stability of the device.

[0024] In one specific implementation, the biological reconstruction ring has multiple locking holes in the bone implantation groove, and the multiple locking holes are spaced apart along the setting direction of the bone implantation groove. The bone block is fixed by locking pins passing through the locking holes.

[0025] By adopting the above technical solution, multiple spaced locking holes are set in the bone block implantation groove. The bone block can be fixed by passing locking pins through the locking holes, which further enhances the biological fixation effect of the interface and improves the stability of acetabular reconstruction.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The designed modular bio-ring reconstruction integrated device for the acetabulum consists of a reconstruction ring embedded in the acetabular fossa to form a metal bone trabeculae, which can reconstruct a complete acetabular fossa. The bio-reconstruction support connects the reconstruction ring to the acetabulum, which can enhance the reconstruction effect of the acetabulum, promote bone ingrowth and bone fusion, and provide effective support and stable reconstruction for the acetabulum. This solves the problem of treating acetabular bone defects, improves the accuracy and safety of surgery, reduces surgical risks, shortens operation time, and improves clinical efficacy.

[0027] The designed modular bio-ring reconstruction integrated device for the acetabulum consists of multiple latitude semi-rings forming a latitude ring and connecting to a meridian support. This allows the device to precisely adapt to different bone defect conditions, improving the acetabular reconstruction effect. It can be flexibly adjusted according to the different bone defect conditions of patients to achieve precise adaptation. The bio-reconstruction support can connect the latitude and meridian combined reconstruction ring to the acetabulum, enhancing the reconstruction effect of the acetabulum and promoting bone ingrowth and bone fusion.

[0028] The designed modular bio-ring reconstruction integrated device for the acetabulum has locking pins inserted into the locking pin holes of the trabecular cone column and extending into the acetabulum. This strengthens the fixation of the trabecular cone column, further ensuring the stability between the various components and improving the acetabular reconstruction effect.

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses an integrated modular bio-ring reconstruction device for the acetabulum. Example

[0039] Reference Figure 1 and Figure 2 A modular bio-ring reconstruction integrated device for the acetabulum includes a combined reconstruction ring 1, a bio-reconstruction support 2, and a connecting component 3. The combined reconstruction ring 1 is embedded inside the acetabular bone to form a metal trabecular "steel skeleton". The bio-reconstruction support 2 is located on the combined reconstruction ring 1, and the connecting component 3 is located on the combined reconstruction ring 1.

[0040] Reference Figure 1 , Figure 2 and Figure 3The combined reconstruction ring 1 includes a latitude and longitude combined reconstruction ring 111, which includes a central fixing ring 111, multiple longitude supports 112, and multiple latitude semi-rings 113. The central fixing ring 111 is made of biocompatible titanium alloy or tantalum metal and has a circular ring structure. Its top is provided with an annular slide rail 1111. The longitudinal section of the annular slide rail 1111 can be T-shaped or dovetail-shaped. In this embodiment, the longitudinal section of the annular slide rail 1111 is T-shaped. The annular slide rail 1111 and the central fixing ring 111 are integrally coaxially arranged. The central fixing ring 111 is embedded in the bottom of the acetabular fossa. The central fixing ring 111 and the acetabulum are locked by an acetabular central fixing pin. Multiple latitude and longitude combined reconstruction rings 111... The meridian supports 112 are all located at the top of the central fixation ring 111, and multiple meridian supports 112 are evenly distributed around the central fixation ring 111. The meridian supports 112 are also made of biocompatible titanium alloy or tantalum metal. One end of each meridian support is provided with a sliding groove 1121 that is adapted to the annular slide rail 1111. The groove can be T-shaped or dovetail-shaped, allowing it to slide freely on the annular slide rail 1111, thus enabling the meridian supports 112 to slide and be positioned. Together, they form an adjustable support structure to adapt to different bone defect conditions. When the prosthesis is implanted into the acetabulum, since the location of the bone defect varies from patient to patient, this structure can be adjusted in position and direction according to the different defect locations.

[0041] Reference Figure 1 and Figure 2 In this embodiment, the warp support 112 is arc-shaped, with its arc opening facing the axis of the central fixing ring 111. Multiple warp supports 112 form a placement area that fits into the acetabular cup 4. A claw 1122 is provided on the side of the warp support 112 away from the annular slide rail 1111, located near the axis of the central fixing ring 111. A locking ring groove 41 is provided at the top of the acetabular cup 4. The claw 1122 engages with the locking ring groove 41 to restrict the rotational freedom of the acetabular cup 4, thus fixing its position and preventing the acetabular cup from rotating. The displacement of cup 4 ensures the stability of acetabular cup 4 during use, avoids a series of problems caused by rotation of acetabular cup 4, and improves the function and service life of hip joint. In addition, the number of meridian supports 112 is 2-6, and the appropriate number can be selected according to the severity of bone defects to flexibly deal with various complex clinical problems of acetabular bone defects. In this embodiment, there are four meridian supports 112. The meridian supports 112 are embedded in the acetabular bone, and their bone integration surfaces (both sides and bottom surface have porous trabecular bone structures to promote bone ingrowth and bone fusion) are all porous structures.

[0042] Reference Figure 2 and Figure 3The central fixing ring 111 has multiple arc grooves 1112 on the top of the annular slide rail 1111. The multiple arc grooves 1112 are evenly distributed around the annular slide rail 1111. The arc grooves 1112 can serve to accurately mark the position during clinical installation. On the other hand, after the position of the warp support 112 is adjusted, the position of the warp support 112 is locked by passing the round-headed top screw through the warp support 112 and the arc grooves 1112.

[0043] Reference Figure 2 In this embodiment, there are four latitude semi-loops 113, which form a latitude ring. The latitude ring is located in the placement area. The warp support 112 has a fixing groove 1123 for placing the latitude ring on the side near the central fixing ring 111. Each end of the latitude semi-loop 113 has a ring groove 1131. One end of the latitude semi-loop 113 extends into the fixing groove 1123 and is press-fitted with the fixing groove 1123. Based on the patient's CT data reconstruction, the warp and latitude combined reconstruction ring 111 can accurately match the defect morphology. Additive manufacturing technology and modern CNC machining technology are used. This technology enables the digital fabrication of bone defects of various complex shapes and allows for simulated surgery before actual operation, making the surgery truly individualized, improving the accuracy and safety of the operation, thereby reducing the risks in actual surgery, shortening the operation time, and improving clinical efficacy. At the same time, the "acetabular centering" technology restores the rotation center to the anatomical position, avoiding fatigue fracture of the scaffold caused by eccentric load. It is made of biocompatible titanium alloy or tantalum metal, and the scaffold with bone trabeculae has a porous structure with high porosity (80%) to promote bone ingrowth. Its elastic modulus is close to that of cancellous bone, reducing stress shielding.

[0044] Reference Figure 2The bio-reconstruction support 2 includes a trabecular conical column 21 made of biocompatible titanium alloy or tantalum metal. A support hole 1124 is provided on the meridian support 112. The trabecular conical column 21 is divided into a threaded section 211 and a fixed section 212. The trabecular conical column 21 passes through the support hole 1124, and the threaded section 211 is located within the support hole 1124 and is threadedly connected to the meridian support 112. The outer wall of the fixed section 212 has a reverse tooth structure. The reverse teeth are arranged from the fixed section 212 to the threaded section 211 towards the side away from the axis of the trabecular conical column 21. The reverse tooth structure can be multiple inclined serrated protrusions. It can be embedded in the cancellous bone of the acetabulum. During surgical implantation, the reverse tooth structure can firmly grasp the cancellous bone like a hook, preventing the biological reconstruction support 2 from loosening and enhancing the fixation effect. The trabecular tapered column 21 has a porous trabecular structure (the thread and reverse tooth structure are solid). The porous trabecular structure has a high porosity to promote bone ingrowth and bone fusion. In order to fill the remaining bone defect, a trabecular filling block is also provided. The trabecular filling block can be made of biocompatible materials, and its shape and size can be selected and adjusted according to the actual bone defect. It is used to fill the remaining bone defect and further improve the reconstruction of the acetabulum.

[0045] Reference Figure 2 The connecting component 3 is a locking pin. A locking pin hole 213 is provided in the middle of the top wall of the trabecular tapered column 21 along its central axis. The locking pin is inserted into the acetabulum through the locking pin hole 213 and is threadedly connected to the trabecular tapered column 21 for strengthening the fixation of the trabecular tapered column 21.

[0046] The implementation principle of Example 1 is as follows: Based on the preoperative design plan for different types of acetabular bone defects and combined with the actual bone defect situation during surgery, different models of components are flexibly selected. This modular bio-ring reconstruction integrated device for the acetabulum, through the adjustable structure of the latitude and longitude combined reconstruction ring 111, can be flexibly adjusted according to the different bone defect conditions of the patients to achieve precise fit. The setting of the bio-reconstruction support 2 and the trabecular bone filling block further enhances the reconstruction effect of the acetabulum, promotes bone ingrowth and bone fusion, and the use of the connecting component 3 ensures the stability between the various components. Overall, this device improves the accuracy and safety of the surgery, reduces surgical risks, shortens the operation time, and improves clinical efficacy. Compared with existing technologies, it can better solve the treatment problem of acetabular bone defects and bring better treatment results to patients. Example

[0047] Reference Figure 4 The difference between this embodiment and embodiment 1 is that the combined reconstruction ring 1 also includes a biological reconstruction ring 12, which is embedded inside the acetabulum.

[0048] Reference Figure 4 , Figure 5 and Figure 6 The bio-reconstruction ring 12 is composed of semi-rings 121, full rings 122, and 2 / 3 rings 123 of different diameters. Clinically, these rings can be freely combined according to the patient's defect location and degree. Specialized surgical tools are used to embed the prosthesis into the acetabular bone, reconstructing a complete acetabular fossa and achieving a dual match between acetabular anatomy and biomechanics. This reconstruction method is not simply a morphological filling of traditional acetabular fillers, but truly forms a bio-integrated body between the acetabular pad prosthesis and bone, further enhancing the stability of the prosthesis-bone interface and the bone ingrowth fixation effect. The bone integration interface of the bio-reconstruction ring 12 is coated with tantalum or a coating containing osteoinductive factors. The coating thickness is 50-200 micrometers, which can further promote bone ingrowth and bone fusion. A bone block implantation groove 124 is provided on the outer wall of the biological reconstruction ring 12. The bone block implantation groove 124 is arranged circumferentially along the outer wall of the biological reconstruction ring 12. The bone block implantation groove 124 can be a rectangular or circular groove for implanting bone blocks or biomaterials to increase the biological fixation effect of the interface. The surface of the biological reconstruction ring 12 that contacts the acetabulum is provided with a porous trabecular structure that mimics cancellous bone. The biological reconstruction ring 12 has multiple locking holes 125 in the bone block implantation groove 124. The multiple locking holes 125 are distributed at intervals along the setting direction of the bone block implantation groove 124. The bone blocks are fixed by passing locking pins through the locking holes 125.

[0049] Reference Figure 6 and Figure 7 The biological reconstruction ring 12 has a threaded hole 126, through which the biological reconstruction support 2 passes. The biological reconstruction ring 12 and the biological reconstruction support 2 are connected by threads. The outer wall of the threaded connection is covered with a tantalum coating to enhance the anti-infection performance. The tantalum coating has good biocompatibility and anti-infection ability, which can effectively prevent the occurrence of infection, improve the success rate of surgery and the patient's recovery. The biological reconstruction ring 12 is made of biocompatible titanium alloy or tantalum metal and has good biological properties. The biological reconstruction ring 12 can be used alone or in combination with the meridian support 112 to form a new reconstruction ring.

[0050] The implementation principle of Example 2 is as follows: The addition of the biological reconstruction ring 12 further improves the function of the modular biological ring reconstruction integrated device for the acetabulum. By freely combining different ring parts, it can more accurately adapt to the patient's bone defect. The coating and bone block implantation groove 124 promote bone ingrowth and biological fixation. The tantalum coating enhances the anti-infection performance. Overall, the device further improves the effect and stability of acetabular reconstruction on the original basis, providing patients with a better treatment plan. Compared with the existing technology, it has made greater progress in solving the problem of acetabular bone defects.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
