Problems solved by technology

However, this method only collects and utilizes the information of the skull (defective part), and discards the information of all the surrounding soft tissues, and the surrounding soft tissues have an important influence or role in the repair of the skull
For example, in operations involving the temporalis muscle, the implant material (skull patch) must be placed between the temporalis muscle and the dura mater (pseudodural mater), so the adhesion between the two needs to be separated during the operation, which is not only complicated but also easily damaged dura mater (false dura mater), and even damage brain tissue, or cause cerebrospinal fluid leak

Embodiment 1

[0057] In this example, for 45 patients with a partial defect on one side of the skull and the opposite side was intact, the required titanium alloy mesh skull patch was prepared.

[0058] Use computed tomography technology to scan the image of the patient's head with a scanning distance of 0.75 mm; store the scanned image in the dicom file format on the mobile hard disk, and then transfer the data to the computer for data processing; use the image processing software minics to read Take the data, segment and extract the data information of the skull and its surrounding soft tissue (24 cases extract the skull information, 21 cases extract the skull and temporal muscle information), reconstruct the three-dimensional model of the skull and its surrounding soft tissue, and then follow the specified path, file name, stored in STL file format; use the graphics processing software magics to read the reconstructed 3D model of the skull and its surrounding soft tissues of interest; Ap...

Embodiment 2

[0060] In this example, 15 patients with bilateral skull defects were prepared to prepare the required skull patch with titanium alloy mesh.

[0061] Use computed tomography technology to scan the image of the patient's head with a scanning distance of 1.5mm; store the scanned image on a recordable CD in dicom file format, and then transfer the data to the computer for data processing; use the image processing software minics Read the data, segment and extract the data information of the skull and its surrounding soft tissues (9 cases extract the skull information, 6 cases extract the skull and temporal muscle information), reconstruct the three-dimensional model of the skull and its surrounding soft tissues, and then follow the specified path, File name, stored in STL file format; use the graphics processing software magics to read the reconstructed 3D model of the skull and its surrounding soft tissues of interest; use the graphics processing software magics to read the shape...

Embodiment 3

[0063] In this example, for 10 patients with only one side of the skull partially defective and the opposite side intact, the required silicone rubber polyester mesh skull patch was prepared.

[0064]Use computed tomography technology to scan the image of the patient's head with a scanning distance of 0.75 mm; store the scanned image in the dicom file format on the mobile hard disk, and then transfer the data to the computer for data processing; use the image processing software minics to read Take data, segment and extract the data information of the skull and its surrounding soft tissues (including 7 cases of skull information extraction, of which 3 patients with unilateral temporal skull injury, extraction of skull and temporal muscle information), reconstruction of the skull and its surrounding soft tissues of interest Then store it in STL file format according to the specified path and file name; use the graphics processing software magics to read the reconstructed 3D prot...

Abstract

The skull patch making process includes the following steps: computerized tomographic imaging to acquire the information of the skull defect part of the patient and the peripheral soft tissue, image designing to reconstruct the 3D head prototype of the patient, designing the dummy for the defect part, leading the designed dummy camber into fast laser forming machine for making patch mold, and final jointing, comparing and cutting titanium web plate to form the ultimate skull patch. The present invention has high precision, low cost, short making period and excellent post-operational restoring.

Description

field of invention [0001] The invention belongs to the fields of cranial bone repair in neurosurgery and medical plastic surgery. Specifically, the invention provides a method for preparing a skull patch. More specifically, the present invention provides a method for preparing a personalized skull patch by using computerized tomography technology to scan the patient's skull and using computer-aided design. Background technique [0002] In neurosurgery, the skull needs to be resected in the following situations: 1) after trauma, infection or tumor invasion, 2) cerebral edema or high intracranial pressure requiring decompression, 3) medical plastic surgery of the skull, etc. Cranial bone loss after craniotomy, for the sake of aesthetics, to prevent re-injury of brain tissue, to restore the sealing of the cranial cavity, and to treat skull defect syndrome, cranioplasty is required. Cranioplastic surgery is one of the oldest and most common elective procedures in neurosurgery....
