Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fixed plate, specifically, relate to a hidden skull fixed plate. BACKGROUND

[0002] When the skull, especially the skull cap, is damaged and repaired by surgery, a screw is generally passed through the fixed plate and fixed on the skull cap on the top of the patient, another screw is passed through the fixed plate and fixed on the fallen skull cap, and thus the fallen skull cap is fixed on the skull cap of the patient by two screws and one fixed plate. However, the top of the two screws will protrude from the top of the patient, and the patient will easily scratch his head during the wound healing process, which will further cause infection and is not conducive to the recovery of the patient.

[0003] Furthermore, the patient will worry about falling when installing two screws on the head, and if the damaged position is on the forehead, the protruding screw will have poor aesthetic appearance, which will increase the psychological burden of the patient. The existing treatment method not only needs to insert a screw into the fallen skull, but also needs to insert a screw into the skull of the patient, which is difficult to fix and has high risk, and the screw is easy to slip during installation, which may further damage the brain. SUMMARY

[0015] In order to make the purpose, technical scheme and advantage of the embodiments of the present utility model more clear, the following will combine the drawings in the embodiments of the present utility model, and the technical scheme in the embodiments of the present utility model is clearly and completely described, obviously, the described embodiments are a part of the embodiments of the present utility model, rather than all the embodiments. The components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but only represents selected embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by the ordinary skilled person in the art without making creative labor belong to the scope of the present utility model protection.

[0017] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0018] In the description of the embodiments of the utility model, it needs to be explained that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the utility model product in common use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0021] Embodiments

[0022] Please refer to Figure 1 The utility model provides a kind of hidden skull fixation plate, including fixed plate body and screw 1, fixed plate body includes fixed part 2, bending part 3 and abutment limiting portion 4, one end of bending part 3 is connected with one end of abutment limiting portion 4, the other end of bending part 3 is connected with one end of fixed part 2;Screw 1 passes through fixed part 2.In some embodiments of the utility model, the side of bending part 3 close to abutment limiting portion 4 is provided with barb 5.The number of barb 5 is multiple and is interval arranged along the extension direction of bending part 3.

[0023] When actually used, such as Figure 1As shown, first, the screw 1 is threaded through the fixing portion 2, and then the fallen skull 6 is fixed by screwing the screw 1 with the bottom of the fallen skull 6, so that the fallen skull 6 and the fixing plate body are first fixed together. Then the fallen skull 6 and the fixing plate body are placed on the patient's head wound position, and the fallen skull 6 and the fixing plate body are pressed downward until the limiting portion 4 abuts against the outer wall of the patient's normal skull 7, and the plurality of barbs 5 are clamped and fixed on the cancellous bone of the patient's normal skull 7, so that the installation process can be completed. Since only the screw 1 needs to be fixed on the fallen skull 6, compared with the conventional method, the screw 1 does not need to be installed on the patient's normal skull 7, the surgical risk is smaller, and the installation is safer; and after installation, the screw 1 is located on the inner wall side of the fallen skull 6, the top of the screw 1 does not protrude from the head, reduces the risk of infection caused by the patient touching, and is more beautiful, reducing the patient's mental burden.

[0024] As Figure 1 shown, in some embodiments of the present application, the fixing plate body is a titanium alloy plate. Since titanium alloy has strong plasticity, the fixing plate body is made of titanium alloy, which is convenient for slightly adjusting and shaping the fixing plate body according to the interval between the fallen skull 6 of the patient and the normal skull 7 of the patient, so as to facilitate the adjustment of the installation depth of the fallen skull 6, and then facilitate the installation of the fallen skull 6 in place.

[0025] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.
