Problems solved by technology

[0005] Specifically, because the physical and chemical properties of the implant made of polyaryletherketone are too stable, it is difficult to form a biological connection with the surrounding tissue, which makes the bonding strength between the implant and the surrounding tissue poor
In addition, there will be a closed space (dead space) between the implant and its surrounding tissue, lacking the filling of vascularized tissue
The above problems may lead to subcutaneous fluid accumulation, wound rupture, soft tissue damage, and inflammation caused by repeated friction of the scalp flap on the implant, which will affect the treatment effect

Embodiment Construction

[0055] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0056] Application overview

[0057] As mentioned earlier, in cranial repair surgery, the implantation of cranial repair materials is not only to restore the shape integrity of the skull, but also to restore the physiological integrity of the skull. Correspondingly, the ideal implant material for skull repair is not only required to match the size and shape of the affected area and have moderate mechanical properties to achieve the integrity of the skull shape, but also requires stable physical and chemical properties and good biocompatibility to achieve P...

Abstract

The invention discloses a skull implant, which comprises an implant main body, which is provided with an upper surface and a lower surface which are opposite to each other; the implant body comprises an upper surface and at least one micro-channel structure formed in the implant body, and each micro-channel structure is provided with at least one communication channel communicated with a first position of the upper surface and a second position of the upper surface. In an operation, after the implant is installed in the cranium of a patient, the upper surface of the implant body faces the scalp flap soft tissue, the lower surface of the implant body faces the dura mater soft tissue, and particularly, the implant for skull repair provides a growth channel for biological tissue in a mode of constructing a micro-pore channel structure; therefore, the combination mode of the implant for skull repair and intracranial tissues is optimized.

Description

technical field [0001] The present application relates to the field of biomedical materials, in particular to skull implants. Background technique [0002] Skull defect is a common craniocerebral disease, which may be caused by trauma, lesions, and decompressive craniectomy. Skull injury will not only affect the appearance of the patient, but also negatively affect the brain function, for example, causing intracranial pressure imbalance, cerebrospinal fluid circulation disorder, headache, dizziness and other symptoms. For adult patients, repair materials need to be implanted in the patient's skull to achieve permanent repair of the skull defect. [0003] The implantation of cranial repair materials in cranial repair surgery is not only to restore the shape integrity of the skull, but also to restore the physiological integrity of the skull. Correspondingly, the ideal implant material for skull repair is not only required to match the size and shape of the affected area and...
