Embodiment 1

[0045] This embodiment provides a bone plate for human skull defect repair, including a bone plate 2, the bone plate 2 has a physiological curvature of the plate surface, and the bone plate 2 is provided with a plurality of through holes 3, the bone plate 2 The edges are connected with a plurality of link plates 4 by screws;

[0046] Bone plate 2 is made of medical polyether ether ketone polymer material through individual design and mechanical processing; figure 2 and image 3 As shown, the physiological curvature α of the bone plate 2 is 15°-120°; the bone plate thickness T of the bone plate 2 is 2-15 mm, and the bone plate length L is 40-200 mm. The diameter D of the through hole 3 is 1.0-8.0 mm, a plurality of through holes 3 are evenly distributed on the bone plate 2, and the distance between the holes is 8 mm-15 mm.

[0047] Medical PEEK (polyether ether ketone) polymer material is the closest material to human bones, non-toxic, good biocompatibility, light weight, co...

Embodiment 2

[0050] In this embodiment, the link plate 4 mentioned in Example 1 is further described in detail. The above-mentioned link plate 4 is a polyetheretherketone link plate with a curvature, and its curvature satisfies the fit between the link plate 4 and the bone plate 2 and the skull. .

[0051] combine figure 1 As shown in the various link plates 4, the link plate 4 is one or two of the polyetheretherketone two-hole link plate, the polyetheretherketone four-hole link plate and the polyether ether ketone snowflake link plate or There are many kinds, and the specific use of the link plate is selected according to the defect of the skull 1. Generally, a variety of link plates are used in conjunction with each other.

Embodiment 3

[0053] This embodiment provides a method for preparing a bone plate for human skull defect repair, comprising the following steps:

[0054] (1) CT scanning of skull 1 to form a three-dimensional skull model of the human body, and three-dimensional reconstruction of the scanned data of the defect of skull 1 to form a three-dimensional image;

[0055] (2) Carry out repair and reconstruction of the defect part on the 3D image obtained in step 1 to form a reconstruction model of the defect part of skull 1, and adjust parameters such as length, width and radian of the repaired defect part according to needs;

[0056] (3) Use the 3D printer to 3D print the human body three-dimensional skull model obtained in step (1) and the reconstructed model of the skull 1 defect part obtained in step (2), so as to obtain the three-dimensional skull model and the defect part model. entity;

[0057] (4) Cooperate the 3D entities obtained in the step (3) with each other to verify the compatibility...

Abstract

The invention provides a bone plate for human skull defect repair and a preparing method and a using method of the bone plate. Compared with a titanium alloy net plate as the first choice for skull repair currently and clinically, the heat conductivity coefficient of the polyether-ether-ketone high polymer material bone plate is low, and the phenomenon of the encephalic discomfort generated by thesensitivity to temperature change after a patient adopts the titanium alloy net plate for repair is avoided. According to a skull defect part CT scanning picture of the patient, after the shape and the size of the defect part are determined, by individually designing processing and preparing, embedded installation and fixation are adopted by an operation, the preoperative cutting and shaping process of the repair of the titanium alloy net plate is replaced, it is avoided that the scalp is injured accidentally since the cutting edge of the titanium net plate is sharp, postoperatively, the outward leakage of cerebrospinal fluid and even a complication of infection caused when the sharp titanium net plate scratches the scalp are thoroughly removed, an artifact existing under an image by theadoption of the titanium alloy net plate for repair is also removed, and the influence of the artifact on later diagnosis and judgment of the state of illness clinically is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bone plate for human skull defect repair, a preparation method and a use method. Background technique [0002] Certain brain neurosurgical diseases can cause intracranial hypertension and edema, and it is usually necessary to remove part of the skull in order to reduce intracranial pressure and save the patient's life. Due to accidental brain trauma, tumors and other diseases, when the brain needs to be operated on, it will also lead to defects in the patient's skull after surgery. The skull defect makes the brain tissue unprotected. When the patient lowers the head, the skull defect will cause encephalocele, and when the head is lifted, the brain tissue will collapse at the skull defect, which not only affects the patient's appearance, but may lead to re-injury of the brain tissue, especially when the skull defect is located In the case of the forehead, th...
