Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of artificial bone structures, in particular to an improved PEEK mesh plate. Background Technique
[0002] Polyetheretherketone (PEEK) is a high polymer composed of repeating units containing a ketone bond and two ether bonds in the main chain structure, belonging to special polymer materials. It has physical and chemical properties such as high temperature resistance and chemical resistance. This material has a large number of applications in the fields of aerospace, medical devices (as artificial bone for repairing bone defects), and industry.
[0003] Such as Figure 6 and Figure 7 shown, it is the PEEK mesh plate structure applied to skull repair in the previous generation. It is similar to the conventional mesh plates on the market and both have fixing grooves and through holes. However, the PEEK mesh plate with this structure has the following deficiencies in actual use: Since there is often a temporal muscle between the connection part of the PEEK mesh plate and the skull, and the temporal muscle is a muscle tissue similar to a scallop shape, which covers the front, upper, and rear of the ear on the side of the head. After the PEEK mesh plate is fixed on the skull, the temporal muscle still needs to be sutured and fixed on the outside of the PEEK mesh plate. Currently, in order to solve this muscle suture problem, the binding wire is often inserted between two through holes at the corresponding position to form a wire buckle, and then the suture is inserted through the wire buckle to suture and fix the muscle tissue. The whole operation process is time-consuming and laborious, which not only increases the workload and difficulty of the actual operation of medical staff, but also reduces the convenience and efficiency of the actual fixing operation of the PEEK mesh plate.
[0004] In view of this, it is particularly important to design and manufacture a PEEK mesh plate structure that is convenient for suturing muscle tissue outside the mesh plate and improves the convenience and efficiency of the actual fixing operation of the mesh plate for application in the direction of artificial bone repair. Content of the Utility Model
[0005] The purpose of the utility model is to propose an improved PEEK mesh plate to solve the problem that when suturing and fixing the temporal muscle for the traditional PEEK skull mesh plate, medical staff need to make wire buckles by themselves, which increases the workload and difficulty of the actual operation of medical staff.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] An improved PEEK mesh plate includes a plate body corresponding to the shape of the skull repair area, a plurality of fixing grooves staggered on the outer edge of the upper end of the plate body, and a plurality of through holes arranged in a rectangular array in the middle of the plate body. A wire fixing structure is arranged on the outside of the plate body for assisting in suturing and fixing muscle tissue outside the plate body through a suture.
[0008] As a further description of the above technical solution:
[0009] The wire fixing structure includes a first wire passing hole, a second wire passing hole, and a third wire passing hole that are fan-shapedly distributed and opened on the outer part of the plate body. The wire hole directions of the first wire passing hole, the second wire passing hole, and the third wire passing hole correspond to the trajectory of the muscle tissue to be sutured on the head.
[0010] As a further description of the above technical solution:
[0011] The cross-sectional shapes of the first wire passing hole, the second wire passing hole, and the third wire passing hole are all U-shaped structures.
[0012] As a further description of the above technical solution:
[0013] The wire fixing structure includes a first arc groove, a second arc groove, and a third arc groove that are fan-shapedly distributed and opened on the outer part of the plate body. Threading members are arranged on the inner sides of the first arc groove, the second arc groove, and the third arc groove.
[0014] As a further description of the above technical solution:
[0015] The threading member includes a rope buckle fixed in the middle of the inner sides of the first arc groove, the second arc groove, and the third arc groove, and a wire passing opening opened in the middle of the rope buckle.
[0016] As a further description of the above technical solution:
[0017] The groove mouth directions of the first arc groove, the second arc groove, and the third arc groove correspond to the trajectory of the muscle tissue to be sutured on the head.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:
[0019] In the present utility model, the original PEEK skull mesh plate structure is scientifically and reasonably improved. Two forms of wire fixing structures for assisting in suturing and fixing muscle tissue to the outside of the plate body through suturing threads are provided on the mesh plate. The two forms of wire fixing structures are both fan-shapedly distributed and correspond to the distribution trajectory of the temporalis muscle tissue. Medical staff only need to use a suture needle to penetrate through the wire passing holes or the rope buckles in the arc grooves to pre-fix the suture thread on the mesh plate, and then operate to suture the muscle tissue at a fixed point outside the mesh plate. This structure can facilitate the suturing and fixing of the temporalis muscle tissue along the trajectory to the outside of the mesh plate, effectively reducing the workload and difficulty of the actual operation of medical staff, thereby improving the convenience and efficiency of the actual fixing operation of the PEEK mesh plate.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to Figures 1-7 , the present utility model provides a technical solution: an improved PEEK mesh plate, including a plate body 1 corresponding to the shape of the skull repair area, a plurality of fixed grooves 101 staggered on the outer edge of the upper end of the plate body 1, and a plurality of through holes 102 arranged in a rectangular array in the middle of the plate body 1. A wire fixing structure is provided outside the plate body 1 for assisting in suturing and fixing muscle tissue to the outside of the plate body 1 through a suture.
[0031] Embodiment 1
[0032] Specifically, as Figure 1 , Figure 2 and Figure 5As shown in the figure, the wire fixing structure includes a first wire passing hole 2, a second wire passing hole 3, and a third wire passing hole 4 that are arranged in a fan shape on the outside of the plate body 1. The wire hole directions of the first wire passing hole 2, the second wire passing hole 3, and the third wire passing hole 4 correspond to the trajectory of the muscle tissue to be sutured at the head, which can improve the effect of suturing and fixing the muscle tissue on the plate body 1.
[0033] Among them, the cross-sectional shapes of the first wire passing hole 2, the second wire passing hole 3, and the third wire passing hole 4 are all U-shaped structures. The setting of such wire passing holes facilitates the insertion of the suture needle with an arc-shaped structure through the plate body 1, can reduce the interference movement between the suture needle and the plate body 1 during the wire routing process, thereby improving the stability of the suture needle wire routing and the contact area after the suture wire is fixed.
[0034] Embodiment 2
[0035] Specifically, as Figure 3 and Figure 4 shown in the figure, the wire fixing structure includes a first arc groove 5, a second arc groove 6, and a third arc groove 7 that are arranged in a fan shape on the outside of the plate body 1. Threading members are arranged on the inner sides of the first arc groove 5, the second arc groove 6, and the third arc groove 7. The threading member includes a rope buckle 8 fixed in the middle of the inner sides of the first arc groove 5, the second arc groove 6, and the third arc groove 7, and a wire passing opening 801 opened in the middle of the rope buckle 8. Among them, the first arc groove 5, the second arc groove 6, and the third arc groove 7 are all arc-shaped structures, which facilitate the insertion of the suture needle with an arc-shaped structure through the plate body 1, can reduce the interference movement between the suture needle and the plate body 1 during the wire routing process. At the same time, during the wire routing process of the suture needle, it can pass through the wire passing opening 801 on the rope buckle 8, and a fixed connection can be established between the suture wire and the rope buckle 8, thereby facilitating the subsequent fixation of the muscle tissue between the plate body 1 and the arc groove.
[0036] At the same time, the groove mouth directions of the first arc groove 5, the second arc groove 6, and the third arc groove 7 correspond to the trajectory of the muscle tissue to be sutured at the head, which can improve the effect of suturing and fixing the muscle tissue on the plate body 1, and can improve the effect of suturing and fixing the muscle tissue on the plate body 1.
[0037] In summary, both of the above-mentioned wire-fixing structures can facilitate the auxiliary suture and fixation of muscle tissue on the outer side of the plate body 1. Compared with the wire-fixing structure in the second embodiment, the wire-fixing structure in the first embodiment has the advantages of low design and manufacturing difficulty, low production cost, and convenient use. However, the muscle tissue after suture adheres tightly to the outer wall of the plate body 1, and the actual effect of suturing and fixing the muscle is worse than that of the wire-fixing structure in the second embodiment. For the wire-fixing structure in the second embodiment, the end of the muscle tissue can be buried into the first arc groove 5, the second arc groove 6, and the third arc groove 7, increasing the suture contact area between the muscle tissue and the plate body 1, enabling the muscle tissue to better fuse on the plate body 1, and improving the healing and regeneration effect of the muscle tissue in the later stage. However, the design, manufacturing difficulty, and production cost of this wire-fixing structure are higher than those of the first wire-fixing structure.
[0038] During the actual use process, according to the actual surgical plan and personalized customization requirements, one of the above-mentioned wire-fixing structures can be selected to perform the routing and fixation of the suture and the suture and fixation of the muscle.
[0039] In addition, the application part of the PEEK mesh plate of the present application is on the part of the skull close to the temporalis muscle. During the actual use process, the above technical solution can be applied to the PEEK mesh plates of other parts (limb bones, trunk bones, or skull bones). According to the muscle orientation and distribution of the relevant parts, a wire-fixing structure suitable for the PEEK mesh plates of other parts is designed, thereby reducing the workload and difficulty of the actual operation of medical staff and improving the convenience and efficiency of the actual fixation operation of the PEEK mesh plate.
[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
