Problems solved by technology

[0003] At present, the commonly used cranial repair prosthesis is titanium alloy mesh and polyetheretherketone mesh. Alloy mesh has the advantages of non-toxicity, low inflammation and sensitization, but there are still the following disadvantages: titanium mesh is often prepared by manual shaping, the process is rough, the process is cumbersome, and the anatomical matching is poor. Good thermal conductivity, while the firmness is not high enough, which limits its further development in the clinic; PEEK patch is a newly developed new implant to replace the titanium alloy mesh, which makes up for the poor thermal insulation and strength of the titanium alloy mesh. Not hig

Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0053] Figure 1 to Figure 6 They are schematic diagrams of the six structures of the anatomical 3D printed mesh skull patch of the present invention.

[0054] Such as figure 1 As shown, the anatomical 3D printed mesh skull patch includes a skull patch edge 1 and a skull patch mesh structure 2 that match the brain injury site; the skull patch edge 1 is a non-porous belt Tentacle structure, tentacle 3 with counterbore 7, such as Figure 13 As shown, the cross-sectional shape of the counterbore 7 is a trapezoidal structure; the mesh structure 2 of the skull patch is composed of a beam structure 4 (such as Figures 9 to 11 Shown) is a continuous mesh formed by random interweaving of multi-layer meshes.

[0055] Such as figure 2 As shown, the anatomical 3D printed mesh skull patch includes a skull patch edge 1 and a skull patch mesh structure...

Abstract

The invention discloses a dissection type 3D printing net-shaped skull patch, and belongs to the technical field of skull repair. The skull patch comprises a skull patch edge matched with a brain injured part and a skull patch mesh structure, the skull patch edge is of a porous tentacle-free structure or pore-free tentacle-free structure or a pore-free tentacle structure. The skull patch mesh structure is formed by randomly weaving single-layer meshes or multi-layer meshes formed by beam structures. The skull patch is matched with the shape and dimension height of an original skull defect portion, and has the good anatomy and biological compatibility; meanwhile, the porous net-shaped design can effectively improve internal and external blood supply of the skull, after the skull patch is implanted, subcutaneous hematoma hematoma puncture drainage difficulty are likely to occur, the dropsy and infection occurrence rate can be lowered, and repairing and healing are promoted.

Description

technical field [0001] The invention relates to the technical field of skull repair, in particular to an anatomical 3D printed mesh skull patch. Background technique [0002] Skull defects are mostly one of the postoperative sequelae of common diseases such as craniocerebral injury, cerebrovascular accident, and intracranial tumor. The purpose of cranial defect repair and plastic surgery is not only to prevent re-injury of brain tissue and restore the physiological airtightness of the cranial cavity, but also to restore the original appearance of the patient and meet the aesthetic requirements, which has good physiological and psychological significance. [0003] At present, the commonly used cranial repair prosthesis is titanium alloy mesh and polyetheretherketone mesh. Alloy mesh has the advantages of non-toxicity, low inflammation and sensitization, but there are still the following disadvantages: titanium mesh is often prepared by manual shaping, the process is rough, t...
