AI Technical Summary
Traditional titanium mesh can easily hinder the healing of soft tissues in the gums during dental implant surgery, leading to exposure of the titanium mesh and gum infection. Furthermore, it is non-absorbable and requires surgical removal, increasing patient pain and burden.
The mesh and bone screws are made of absorbable biomaterials. The mesh is fixed in the dental bone by rotating the rope through the bone screws, and the absorbable material avoids the need for removal during later surgery.
The automatic degradation of the mesh reduces the patient's subsequent pain and medical burden, and avoids the need for surgical removal.

Abstract
Description
Technical Field
[0001] This application relates to the field of medical dental technology, specifically to an absorbable mesh device for fixing bone graft materials. Background Technology
[0002] In dental implant surgery, medical titanium mesh serves as a supporting structure for the implant, ensuring its stability and long-term success rate. However, traditional titanium mesh can easily hinder the healing of gingival soft tissue, leading to mesh exposure, gingival infection, and the non-absorbable nature of the mesh necessitates surgical removal later, increasing patient pain and burden. Utility Model Content
[0003] The main objective of this application is to provide an absorbable mesh device for fixing bone graft materials, which aims to solve the above-mentioned technical problems.
[0004] The technical solution adopted in this application is as follows:
[0005] An absorbable mesh device for fixing bone graft materials includes a mesh and bone screws. The mesh is made of absorbable biomaterial, and tightening cords are provided at the four corners of the mesh. Each tightening cord is wound around a bone screw.
[0006] Optionally, the bone screw includes a shank and a cap, the shank being threaded and the cap being an open groove.
[0007] Optionally, the absorbable biomaterial can be any one of protein-based materials, natural ester-based materials, or synthetic ester-based materials.
[0008] Compared with the prior art, the beneficial effects of this application are:
[0009] This application proposes an absorbable mesh device for fixing bone graft materials. By covering the bone graft material with a mesh, bone screws are screwed into the dental bone. The rotation of the bone screws drives a tightening rope to tighten the mesh for better fixation of the bone graft material. Moreover, the mesh is made of absorbable material, so it does not need to be removed surgically later, reducing the patient's later pain and burden. Attached Figure Description

[0011] Explanation of the labels in the attached drawings:
[0012] 1-Weaving net, 2-Tightening rope, 3-Bone nail. Detailed Implementation
[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0014] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0015] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0016] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.
[0017] See attached document Figure 1 This application provides an absorbable mesh device for fixing bone graft materials, including a mesh 1 and a bone nail 3. The mesh 1 is made of absorbable biomaterial and replaces the traditional titanium mesh for fixing bone graft materials. The mesh 1 can be automatically degraded and absorbed in the later stage, eliminating the trouble of surgical removal and reducing the patient's later pain and medical burden.
[0018] like Figure 1As shown, to secure the mesh 1, tightening ropes 2 are provided at the four corners of the mesh 1. The tightening ropes 2 are made of the same material as the mesh 1. Each tightening rope 2 is wound around a bone screw 3 opposite to the other. The bone screw 3 includes a screw rod and a top cap. The screw rod is threaded for screwing into the dental bone for fixation. The tightening ropes 2 are wound around the screw rod.
[0019] The top cap has an open groove to facilitate the use of tools to screw the bone screw 3 into the dental bone. During the operation, by screwing the bone screw 3 into the dental bone, the rope 2 is rolled up and tightened as the bone screw 3 rotates, thereby tightening the mesh 1 to fix the bone graft material.
[0020] Yes, the absorbable biomaterials used in the netting 1 and the tightening rope 2 can be any one of the following: protein materials, natural ester materials, or synthetic ester materials, such as any one of cystine, silk fibroin, polycaprolactone, polyhydroxybutylene, polyglycolic acid, or polydioxanone.
[0021] In summary, the absorbable mesh device for fixing bone graft materials provided in this application embodiment can be set to the size of the mesh according to actual needs. The bone graft material is fixed by rotating the bone screw into the dental bone and tightening the mesh. At the same time, since the mesh itself is an absorbable biomaterial, it does not need to be removed by special surgery later, which greatly reduces the patient's pain and medical burden.
[0022] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
