Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a standardized ankle joint filling block. Background Art

[0002] Ankle injury is a common bone disease, which is mainly manifested as fracture, wear and tear or other forms of damage to the ankle joint. In order to treat this injury, surgical repair is usually required and a prosthesis is used to fill the damaged area. In recent years, with the advancement of medical technology, the application of ankle prostheses has become more and more widespread, which not only improves the patient's recovery speed, but also significantly improves the quality of life.

[0003] At present, the main method for treating ankle injuries in related technologies is to use customized prostheses. The basic process of this method includes: first, obtaining the patient's three-dimensional data through CT scanning, then building a three-dimensional model based on this data, and designing a personalized prosthesis according to the specific circumstances of the injury. Next, the prosthesis is made through 3D printing or traditional manufacturing processes, and finally the prosthesis is implanted in the patient's body. However, the production cycle of customized prostheses is long and the cost is high, which is a considerable burden for many patients.

[0004] In addition, some general circular prostheses are also provided in the related art, but such prostheses are mainly used for relatively simple cases and are not suitable for complex or irregular injuries. Moreover, when using general circular prostheses, some doctors will choose to directly remove a large range of healthy bones to ensure that the prosthesis can be firmly installed in the damaged part, which results in a large amount of healthy bones being removed unnecessarily, thereby increasing the risk of surgery and the difficulty of postoperative recovery. Summary of the invention

[0005] In order to shorten the manufacturing cycle and reduce the range of bone resection, the present application provides a standardized ankle joint filling block.

[0006] The standardized ankle joint filling block provided in this application adopts the following technical solution: A standardized ankle joint filling block includes a patch block, the patch block has a regular hexagonal structure, a half key groove is provided at the center of each outer side wall of the patch block, the half key groove is used to be combined with the half key groove on another patch block to form a full key groove, and the full key groove is used to guide a connecting key; a positioning pile, the positioning pile is provided on one side of the patch block, and the positioning pile is used to be nailed into the patient's bone.

[0007] By adopting the above technical solution, the standardized ankle joint filling block can effectively adapt to various shapes of trauma areas, significantly reducing the time and cost required for individual customization. The hexagonal structure design not only improves the stability and connection strength between the patches, but also allows doctors to flexibly select and combine patches of different specifications according to actual needs, thereby reducing the range of osteotomy, better preserving the patient's healthy bone, reducing surgical risks, and improving postoperative recovery. In addition, the design of the positioning pile helps to ensure that the patch is accurately fixed in the predetermined position, further enhancing the stability of the overall structure.

[0008] Optionally, the half pin groove includes a straight groove and a semicircular groove, the semicircular groove is arranged at one end of the straight groove away from the center of the patch block, and the whole pin groove includes a strip groove formed by two straight grooves and a full circular groove formed by two semicircular grooves, and the full circular groove is arranged at the central position of the strip groove.

[0009] By adopting the above technical solution, the half pin groove is designed as a combination of a straight groove and a semicircular groove, so that a complete pin groove can be formed when two patches are assembled. This design ensures that the connecting key can be inserted accurately and firmly, thereby enhancing the stability and reliability of the entire filling structure. At the same time, it effectively prevents the misalignment between patches and ensures the recovery effect after surgery.

[0010] Optionally, the connecting key includes a strip portion for cooperating with the strip groove and a full-circle portion for cooperating with the full-circle groove, the full-circle portion is arranged at the central position of the strip portion, and a first pointed cone portion is provided at one end of the connecting key.

[0011] By adopting the above technical solution, the connection key can be accurately embedded in the integral key slot between the patch blocks, ensuring that adjacent patch blocks are firmly connected. The design of the first pointed cone portion makes the connection key easy to insert, improving the convenience of operation.

[0012] Optionally, both sides of the patch are provided with rounded corners.

[0013] By adopting the above technical solution, the rounded corners can effectively avoid damage to surrounding healthy tissues during installation, while improving the safety and convenience of surgical operations. The rounded corner design also makes it easier for the patch to transition smoothly with the surrounding bone, facilitating bone growth, while reducing stress concentration and further enhancing the overall stability and biocompatibility of the filling block.

[0014] Optionally, the positioning pile includes a pile body and a second pointed cone portion, and the surface of the pile body is provided with anti-slip textures.

[0015] By adopting the above technical solution, the positioning pile can be more firmly fixed in the patient's bone, preventing the prosthesis from shifting due to loosening, and improving the success rate of the operation and the patient's rehabilitation effect. At the same time, the anti-slip pattern increases the friction between the pile body and the bone, which can stimulate bone growth and promote patient recovery.

[0016] Optionally, a filling groove is provided on the outer wall of the pile body along the extension direction of the pile body, and the filling groove is used to fill bone cement.

[0017] By adopting the above technical solution, during the operation, bone cement can be injected into the gap between the patient's bone and the positioning pile through the filling groove, thereby improving the bonding strength between the positioning pile and the bone and ensuring that the patch is firmly fixed to the injured part. At the same time, the design of the filling groove can also increase the contact area, further enhance the mechanical locking effect, and improve the stability and reliability of the overall structure.

[0018] Optionally, the patch includes a central entity and a trabecular bone layer arranged circumferentially of the central entity.

[0019] By adopting the above technical solution, the trabecular layer has a disordered lattice structure, which can simulate the porous disordered characteristics of human cancellous bone, increase the porosity of bone, and promote blood penetration and bone cell growth. In addition, the disordered structure of the trabecular layer increases friction, further improves the fixation effect of the patch, reduces the risk of postoperative displacement, and achieves more effective bone healing and long-term stability.

[0020] Optionally, the patch and the positioning pile are integrally formed and made of biocompatible material.

[0021] By adopting the above technical solution, the overall stability and reliability of the filling block are ensured, and the risk of failure caused by loose connection parts is reduced. At the same time, the application of biocompatible materials effectively avoids postoperative rejection reactions and improves the patient's comfort and healing speed.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By using regular hexagonal patches and combining them into a honeycomb structure, the overall stability and mechanical strength are enhanced, making the prosthesis more solid and reliable when under pressure; 2. The half-key slot design between the patches allows any number of patches to be spliced ​​together, which can flexibly cope with various irregular ankle injuries, reduce the amount of healthy bone removed, and reduce surgical risks and postoperative recovery difficulties; 3. The design of the positioning post helps to fix the patch and ensure that it is firmly embedded in the patient's bone. At the same time, the anti-slip texture and filling groove on the surface of the post further improve the reliability of fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a standardized ankle joint filling block.

[0029] like Figure 1 and Figure 2 As shown, the standardized ankle joint filling block includes a patch 1, which has a regular hexagonal structure. A half key groove 101 is provided at the center of each outer side wall of the patch 1. The half key groove 101 is used to be assembled with the half key groove 101 on another patch 1 to form a whole key groove 3. The whole key groove 3 is used to guide the connecting key; a positioning pile 2, which is provided on one side of the patch 1 and is used to be nailed into the patient's bone.

[0030] The standardized ankle joint filling block disclosed in the embodiment of the present application can effectively adapt to various shapes of trauma areas, significantly reducing the time and cost required for individual customization. The design of the hexagonal structure not only improves the stability and connection strength between each patch 1, but also allows doctors to flexibly select and combine different numbers of patches 1 of the same specification according to actual needs, thereby reducing the osteotomy range, better preserving the patient's healthy bone, reducing surgical risks, and improving postoperative recovery effects. In addition, the design of the positioning pile 2 helps to ensure that the patch 1 is accurately fixed in the predetermined position, further enhancing the stability of the overall structure.

[0031] like Figure 1 and Figure 2As shown, the half pin slot includes a straight slot 1011 and a semicircular slot 1012, the semicircular slot 1012 is arranged at one end of the straight slot 1011 away from the center of the patch 1, and the whole pin slot includes a strip slot formed by two straight slots 1011, and a full circular slot formed by two semicircular slots 1012, and the full circular slot is arranged at the center of the strip slot. In order to match the whole pin slot, the connecting key includes a strip portion for matching with the strip slot and a full circular portion for matching with the full circular slot, the full circular portion is arranged at the center of the strip portion, and one end of the connecting key is provided with a first pointed cone portion.

[0032] The design of the half pin groove adopts a combination of a straight groove and a semicircular groove to ensure that a complete pin groove can be formed when two patches 1 are spliced. This design ensures the accurate and stable insertion of the connecting key, thereby improving the stability and reliability of the entire filling structure. At the same time, this design effectively avoids the misalignment between the patches 1 and ensures the stability of the postoperative recovery effect. The connecting key can be accurately embedded in the whole key groove 3 between the patches 1, ensuring the firm connection of adjacent patches 1. In addition, the design of the first pointed cone makes the insertion of the connecting key more convenient, improving the efficiency of the surgical operation.

[0033] like Figure 1 and Figure 2 As shown, both sides of the patch 1 can be provided with rounded corners. The rounded corners can effectively avoid damage to the surrounding healthy tissue during the installation process, while improving the safety and convenience of the surgical operation. The rounded corner design also makes it easier for the patch 1 to smoothly transition with the surrounding bone, facilitates bone growth, and reduces stress concentration, further enhancing the overall stability and biocompatibility of the filling block.

[0034] like Figure 1 and Figure 2 As shown, the positioning pile 2 includes a pile body 201 and a second pointed cone portion 202. The surface of the pile body 201 is provided with anti-slip patterns. The outer wall of the pile body 201 is provided with a filling groove 203 arranged along the extension direction of the pile body 201, and the filling groove 203 is used to fill bone cement.

[0035] The design of the second pointed cone 202 makes the insertion of the pile body 201 more convenient. The introduction of the anti-slip pattern increases the friction coefficient between the pile body 201 and the bone, promotes the growth of the bone, accelerates the patient's recovery process, and also effectively prevents the displacement of the prosthesis caused by loosening, thereby improving the success rate of the operation and the patient's rehabilitation effect. During the operation, bone cement is injected into the gap between the patient's bone and the positioning pile 2 through the filling groove 203, which further enhances the bonding strength between the positioning pile 2 and the bone, ensuring that the patch 1 is firmly fixed at the injured site. At the same time, the design of the filling groove 203 can also expand the contact area, further enhance the mechanical locking effect, and thus enhance the stability and reliability of the overall structure.

[0036] like Figure 1-Figure 3 As shown, the patch 1 includes a central entity 102 and a trabecular layer 103 arranged circumferentially of the central entity 102. The trabecular layer 103 has a disordered lattice structure, which can simulate the porous disordered characteristics of human cancellous bone, increase the porosity of bone, and promote blood penetration and bone cell growth. In addition, the disordered structure of the trabecular layer 103 increases friction, further improves the fixation effect of the patch 1, reduces the risk of postoperative displacement, and achieves more effective bone healing and long-term stability.

[0037] In order to increase the biocompatibility of the filling block, the patch 1 and the positioning pile 2 are integrally formed and made of biocompatible materials. The material of the connecting key is the same as that of the patch 1. In this embodiment, the patch 1, the positioning pile 2 and the connecting key are all made of titanium alloy, which effectively avoids postoperative rejection and improves the patient's comfort and healing speed.

[0038] The implementation principle of a standardized ankle joint filling block in the embodiment of the present application is as follows: The working principle of the standardized ankle joint filling block mainly includes the following aspects: First, the filling block adopts a patch block 1 design with a regular hexagonal structure, and a half key groove 101 is provided at the center of each outer wall. These half key grooves 101 can be combined with the half key grooves 101 on another patch block 1 to form a complete key groove 3 for guiding the insertion of the connection key. This design allows doctors to flexibly select and combine different numbers of patches 1 of the same specification according to actual needs to adapt to wound areas of various shapes, while improving the stability and connection strength between the patches 1.

[0039] Secondly, the connection key is designed to be precisely embedded in the integral key slot 3 between the patches 1 to ensure a firm connection between adjacent patches 1. The connection key includes a strip portion and a full circular portion, which respectively cooperate with the strip groove and the full circular groove of the full key slot 3. The design of the first pointed cone portion makes the insertion of the connection key more convenient, thereby improving the efficiency of the surgical operation.

[0040] Furthermore, the design of the positioning pile 2 helps to ensure that the patch 1 is accurately fixed at the predetermined position. The positioning pile 2 includes a pile body 201 and a second pointed cone portion 202. The pile body 201 is used to be nailed into the patient's bone. The design of the second pointed cone portion 202 makes the insertion of the pile body 201 more convenient. The surface of the pile body 201 is provided with anti-slip lines, which increases the friction coefficient between the pile body 201 and the bone, promotes the growth of the bone, and also effectively prevents the displacement of the prosthesis caused by loosening. In addition, the outer wall of the pile body 201 is provided with a filling groove 203 for filling bone cement, which further enhances the bonding strength between the positioning pile 2 and the bone.

[0041] Finally, the design of the patch 1 also includes a central entity 102 and a trabecular layer 103 arranged around the central entity 102. The trabecular layer 103 has a disordered lattice structure, which can simulate the porous disordered characteristics of human cancellous bone, increase the porosity of bone, and promote blood penetration and bone cell growth. At the same time, the patch 1 and the positioning pile 2 are integrally formed and made of biocompatible materials, which effectively avoids postoperative rejection reactions and improves the patient's comfort and healing speed.

[0042] In summary, the standardized ankle filling block achieves effective filling and fixation of the ankle joint trauma area through the clever patch 1 splicing design, precise embedding of the connecting key, firm fixation of the positioning pile 2 and the biocompatible design of the trabecular bone layer 103, thereby reducing surgical risks and improving postoperative recovery effects.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
