Description

Technical Field

[0001] This utility model relates to the field of medical fixation nail technology, and in particular to a gingival anchor fixation nail that can be tied with a suture. Background Technology

[0002] In dental implant and periodontal ligament-gingival surgery, a good integration of the implant with the surrounding soft and hard tissues is crucial to ensuring long-term functional stability and aesthetic results. Implant stability depends on osseointegration, while soft tissue healing directly affects peri-implant sealing, aesthetics, and resistance to infection. However, postoperative soft tissue shrinkage is a common clinical problem, especially in patients with insufficient keratinized gingiva. Significant recession of the transplanted tissue flap or in situ soft tissue is prone to occur, leading to a reduction or even loss of keratinized gingiva width. This can result in complications such as peri-implantitis, gingival contour asymmetry, and excessively long clinical crowns, severely impacting the long-term success rate of implant restorations.

[0003] Currently, precise alignment and stable fixation of soft tissue mainly rely on suturing techniques, but traditional suturing has limitations. First, tension control is insufficient: after suturing, the tissue flap may still experience micro-movements due to muscle traction or oral function movements, affecting tension-free healing. Second, contraction is difficult to avoid: even with tension-reducing suturing, the soft tissue may still contract postoperatively due to insufficient blood supply, scar contracture, or mechanical stimulation. Third, maintaining keratinized gingiva is difficult: in cases of stenotic keratinized gingiva, suturing is insufficient to completely prevent displacement of the free gingiva or transplant flap, leading to further loss of keratinized gingiva.

[0004] Currently, there are no retention devices specifically designed for gingival fixation. Clinicians can only improve soft tissue stability by modifying suture techniques (such as horizontal mattress sutures and suspension sutures) or combining them with biofilm coverage, but the effects are limited. Therefore, there is an urgent need for suture-binding gingival anchors to overcome the shortcomings of existing technologies. Utility Model Content

The guide section facilitates gingival tissue growth, preventing gingival atrophy. Furthermore, the physical isolation provided by the guide section reduces instrument manipulation obstacles caused by postoperative gingival tissue hyperplasia. By ensuring a smooth transition between the suture binding section and the guide section, the suture can easily slide from the crawling section into the binding section, allowing clinical suture binding to be completed without additional auxiliary tools, significantly improving overall operational efficiency.

[0011] Furthermore, the guide section is a cylindrical structure, the transition section is a columnar structure, and the sidewall of the transition section is a circular arc transition surface.

[0012] Furthermore, the guide section has a chamfered section on the side near the binding part; The chamfered section forms a frustum-shaped structure, and the diameter of the chamfered section gradually decreases from the crawling part to the implantation part until it is equal to the diameter of the end of the binding part.

[0023] See appendix Figures 1-3 This embodiment provides a gingival anchor fixation pin with a suture binding, comprising: an implantation part 1 capable of being implanted into the alveolar bone, including an insertion section 11 and a first connecting section 12 connected in sequence, the insertion section 11 being fixedly connected to the alveolar bone; a crawling part 3 capable of being at least partially disposed in the gingiva, the crawling part 3 including a guide section 31 and a transition section 32 along its length; and a suture binding part 2 capable of fixing the connecting wire, the suture binding part 2 being disposed between the implantation part 1 and the crawling part 3, the two ends of the suture binding part 2 being fixedly connected to the first connecting section 12 and the end of the guide section 31 away from the transition section 32, respectively, the diameter of the suture binding part 2 being smaller than the diameter of the guide section 31, the connection position of the suture binding part 2 and the guide section 31 being smoothly transitioned, and under the action of external force, the connecting wire can slide from the crawling part 3 into the suture binding part 3. The suture section 2; by setting the implantation section 1, this utility model can achieve a fixed connection with the alveolar bone, ensuring the stability of the gingival anchor installation. The guide section 31 can be placed in the gingival tissue and adapt to the natural gap of the gingival tissue to form a guiding crawling channel for the gingival tissue, thereby facilitating gingival tissue growth and preventing gingival tissue atrophy. At the same time, the physical isolation effect of the guide section 31 can reduce the instrument operation obstacles caused by postoperative gingival tissue hyperplasia. By setting the transition section 32, the friction damage to the oral mucosa caused by the installation of the gingival anchor can be reduced. By setting the connection position between the suture section 2 and the guide section 31 to be a smooth transition, the connecting suture can be easily slid from the crawling section 3 into the suture section 2, so that the clinical suture binding operation can be completed without additional auxiliary tools, significantly improving the overall operation efficiency.

[0024] In some possible embodiments, the guide segment 31 and the transition segment 32 are integrally formed. By forming the guide segment 31 and the transition segment 32 as an integral part, the processing steps can be simplified and the manufacturing cost can be reduced.

[0025] In some other possible embodiments, the guide section 31 and the transition section 32 are detachably configured, and the connection structure between the guide section 31 and the transition section 32 is not limited, as long as the guide section 31 and the transition section 32 are detachably connected.

[0026] Specifically, one of the guide section 31 and the transition section 32 is provided with a first snap-fit ​​structure, and the other is provided with a second snap-fit ​​structure. The guide section 31 and the transition section 32 are engaged and connected through the first snap-fit ​​structure and the second snap-fit ​​structure.

[0027] Specifically, one of the guide section 31 and the transition section 32 is provided with an internal thread, and the other is provided with an external thread. The guide section 31 and the transition section 32 are connected by threads.

[0028] Preferably, the end connecting the guide section 31 and the transition section 32 is provided with a stepped structure. The outer diameter of the stepped structure is smaller than the outer diameter of the guide section 31 body. The stepped structure is provided with an external thread, and the transition section 32 is provided with an internal thread. The transition section 32 is sleeved on the stepped structure, and the transition section 32 is threadedly connected to the stepped structure. At the same time, the connection position between the stepped structure and the guide section 31 body can limit the transition section 32.

[0029] In some possible embodiments, the crawling part 3 includes at least one guide segment 31 and at least one transition segment 32. By setting at least one guide segment 31 and at least one transition segment 32, different numbers of guide segments 31 and transition segments 32 can be set according to the depth of the gingival tissue of the patient to be implanted. This can improve the application range of the gingival anchor while ensuring the implantation effect of the anchor.

[0030] Specifically, when the crawling part 3 includes two or more guide sections 31, adjacent guide sections 31 can be detachably connected; when the crawling part 3 includes two or more transition sections 32, adjacent transition sections 32 can be detachably connected.

[0031] Preferably, the crawling section 3 includes a guide section 31 and a transition section 32.

[0032] In some possible embodiments, the gingival anchor includes at least one suture portion 2. When the gingival anchor includes two or more suture portions 2, two adjacent suture portions 2 are arranged adjacently, and in the direction from the crawling portion 3 to the implantation portion 1, the two or more suture portions 2 are arranged adjacently, and the connection position of the two suture portions 2 is smoothly transitioned, so as to avoid frictional damage to the oral mucosa of the patient to be implanted. By providing two or more suture portions 2, the area that can be tied can be increased, which prepares for situations where a large number of sutures are required, thereby improving the fit range of the gingival anchor.

[0033] In some possible embodiments, the end of the transition section 32 away from the guide section 31 is provided with a staple holding area 321, which can accommodate a staple holder; the cross-sectional shape of the staple holding area 321 is a D-shaped structure, a hexagonal structure or a polygonal structure with more than one hexagon. By providing the staple holding area 321, it is easy for the staple holder to clamp it, so as to accurately implant the gingival anchor fixation staple into the implantation position.

[0034] In this embodiment, the screw-holding installation area 321 is an inner cavity structure with one end open, embedded in the transition section 32. The inner cavity structure is provided with anti-slip texture or limiting protrusion, which can ensure that the screw holder is stably connected to the screw-holding installation area 321, and further realize the precise implantation of the gingival anchor fixation screw into the implantation position.

[0035] Specifically, the depth of the nail-holding installation area 321 is not limited, as long as it can be securely connected to the nail holder.

[0036] Specifically, the size and shape of the nail-holding installation area 321 are not limited, but are adapted to the size and shape of the nail holder.

[0037] In some possible embodiments, the binding part 2 is a receiving groove with a diameter smaller than that of the first connecting section 12. By setting the binding part 2 as a receiving groove, it is easy to accommodate the connecting wire and confine the connecting wire within the receiving groove, making it difficult for the connecting wire to shift and ensuring the stability of the connection between the connecting wire and other structures.

[0038] In this embodiment, the shape of the receiving groove is not limited, as long as it can accommodate the connecting wire.

[0039] Preferably, the shape of the receiving groove is U-shaped, and the depth of the receiving groove gradually changes. This arrangement facilitates the rapid sliding of the connecting line on the crawling part 3 into the receiving groove.

[0040] In this embodiment, the diameter of the bottom of the receiving groove is smaller than the diameter of the first connecting end 12.

[0041] In this embodiment, the sidewall of the guide section 31 is a smooth structure, and the receiving groove is a smooth structure.

[0042] In some possible embodiments, the depth of the receiving groove gradually increases to a maximum depth from the direction from the crawling part 3 to the implantation part 1; the depth of the receiving groove gradually increases to a maximum depth from the direction from the implantation part 1 to the crawling part 3. With the above arrangement, it is easy for the receiving groove to accommodate the connecting wire, and it is easy for the connecting wire on the crawling part 3 to slide quickly into the receiving groove.

[0043] In this embodiment, from the crawling part 3 to the implantation part 1, the depth of the receiving groove gradually increases to the maximum depth, and then the depth of the receiving groove gradually decreases to zero. The position where the depth of the receiving groove is zero is the connection position between the first connecting section 12 and the binding part 2.

[0044] In some possible embodiments, the diameter of the guide segment 31 is larger than the diameter of the first connecting segment 12. The extension segment and the first connecting segment 12 are structures that connect and cooperate with the alveolar bone. The diameter of the guide segment 31 is adapted to the natural gap of the gingival tissue. By setting the diameter of the guide segment 31 to be larger than the diameter of the first connecting segment 12, the size of the implant part 1 can be reduced as much as possible while ensuring the crawling guidance effect of the guide segment 31 on the gingival tissue, thus reducing the difficulty of implantation.

[0045] In this embodiment, the diameter of the crawling part 3 is larger than the diameter of any position of the binding part 2, and the diameter of the crawling part 3 is larger than the diameter of any position of the implantation part 1.

[0046] In this embodiment, the length direction of the gingival anchor fixation pin is parallel to the direction from the crawling part 3 to the implantation part 1.

[0047] The length of the crawling part 3 is greater than the length of the implantation part 1, and the length of the crawling part 3 is greater than the length of the binding part 2, while the length of the implantation part 1 is greater than the length of the binding part 2.

[0048] Furthermore, the length of the first connecting segment 12 is less than the length of the extending segment 11, and the length of the first connecting segment 12 is greater than the length of the binding part 2.

[0049] In some possible embodiments, the guide segment 31 is a cylindrical structure, and the transition segment 32 is a columnar structure with a rounded transition surface on the sidewall of the transition segment 32. By setting the guide segment 31 to a cylindrical structure, it can adapt to the natural gaps in the gingival tissue, forming a guiding crawling channel for the gingival tissue, thereby facilitating gingival tissue growth and preventing gingival tissue atrophy. At the same time, the physical isolation effect of the guide segment 31 can reduce instrument operation obstacles caused by postoperative gingival tissue hyperplasia. The transition segment 32 is set to a columnar structure with a rounded transition surface on the sidewall, which can effectively reduce frictional damage to the oral mucosa when implanting the gingival anchor fixation pin, reducing the discomfort of the implanter during the implantation process.

[0050] In this embodiment, the length of the guide segment 31 is not limited, as long as the guide segment 31 can guide the gingival tissue to crawl; the length of the transition segment 32 is not limited, and the specific size is set according to actual needs.

[0051] Preferably, the length of the guide section 31 is greater than the length of the transition section 32.

[0052] In some possible embodiments, the guide section 31 is provided with a chamfered section 33 on the side near the binding part 2; the chamfered section 33 forms a frustum structure, and the diameter of the chamfered section 33 gradually decreases from the crawling part 3 to the implantation part 1 until it is equal to the diameter of the end of the binding part 2. By providing the chamfered section 33, a smooth guide structure without sharp angles can be formed on the crawling part 3, which is convenient for binding the connecting line after surgery. Specifically, it is convenient for the connecting line to automatically slide into the anchoring position of the binding part 2 through the tissue gap, avoiding the problem of the connecting line getting stuck or unable to be smoothly inserted into the binding part caused by the traditional right angle structure.

[0053] In this embodiment, the diameter of the chamfered section 33 gradually decreases from the diameter of the guide section 31 body to the maximum diameter of the binding section 2.

[0054] In some possible embodiments, the diameter of the transition section 32 gradually increases from the crawling part 3 to the implantation part 1 until it is equal to the diameter of the guide section 31. By setting the diameter of the transition section 32 to gradually change, abrupt changes in the size of the transition section 32 or large differences in the size of the connection position between the transition section 32 and the guide section 31 are avoided. This can further reduce frictional damage to the oral mucosa when implanting the gingival anchor fixation pin and reduce the discomfort of the implanter during the implantation process.

[0055] In some possible embodiments, the insertion section 11 is a variable diameter structure, with the diameter of the insertion section 11 gradually decreasing from the crawling part 3 to the implantation part 1. The insertion section 11 is provided with threads. As can be seen from the above configuration, the insertion section 11 is a screw structure. This configuration facilitates the connection between the insertion section 11 and the alveolar bone, and improves the stability of the connection between the insertion section 11 and the alveolar bone.

[0056] In some possible embodiments, the axis of the implantation part 1, the axis of the binding part 2, and the axis of the crawling part 3 are arranged to coincide. This arrangement ensures that the implantation part 1, the binding part 2, and the crawling part 3 form a regular nail-like structure after connection, which facilitates the implantation of the above-mentioned gingival anchor fixation nail, while improving the aesthetics of the gingival anchor fixation nail and reducing the manufacturing cost.
