Embodiment 1

[0052] like Figure 5 As shown in the picture on the left, the patient has an aneurysm in the internal carotid artery segment. According to the situation of this patient, the preparation method of the personalized aneurysm clip provided by the present invention is as follows:

[0053] 1) CT angiography (CTA) is used in the hospital to scan and store the image data of the patient's vascular aneurysm.

[0054] 2) Import the dicom format data file of CTA thin-layer scanning into the mimics software to obtain the image; locate the up, down, left, and right directions of the image, that is, select the four directions of ATRL; then select the gray level of the image, and adjust the gray level range according to the required tissue Select, the gray value range needs to include the aneurysm and the parent vessel; calculate the mask with a specific gray value, convert it to a 3D model, complete the 3D reconstruction of the aneurysm, and simulate the 3D structure of the patient's aneury...

Embodiment 2

[0067] This embodiment is a patient with anterior communicating artery aneurysm. For the situation of this patient, the process flow of the preparation method of the personalized aneurysm clip provided by the present invention is as follows:

[0068] 1) CT angiography (CTA) is used in the hospital to scan and store the image data of the patient's vascular aneurysm.

[0069] 2) Import the dicom format data file of CTA thin-layer scanning into the mimics software to obtain the image; locate the up, down, left, and right directions of the image, that is, select the four directions of ATRL; then select the gray level of the image, and adjust the gray level range according to the required tissue Select, the gray value range needs to include the aneurysm and the parent vessel; calculate the mask with a specific gray value, convert it to a 3D model, complete the 3D reconstruction of the aneurysm, and simulate the 3D structure of the patient's aneurysm. like Figure 8 shown.

Embodiment 3

[0082] There is an aneurysm in the patient's internal carotid artery segment, and for the situation of this patient, the process flow of the preparation method provided by the present invention is as follows:

[0083] 1) CT angiography (CTA) is used in the hospital to scan and store the image data of the patient's vascular aneurysm.

[0084] 2) Import the dicom format data file of CTA thin-layer scanning into the mimics software to obtain the image; locate the up, down, left, and right directions of the image, that is, select the four directions of ATRL; then select the gray level of the image, and adjust the gray level range according to the required tissue Select, the gray value range needs to include the aneurysm and the parent vessel; calculate the mask with a specific gray value, convert it to a 3D model, complete the 3D reconstruction of the aneurysm, and simulate the 3D structure of the patient's aneurysm. like Figure 11 shown.

[0085] 3) Measure the diameter, lengt...

Abstract

The invention relates to a preparing method for an individualized aneurysm clamp and an aneurysm clamp. The preparing method includes the following steps that 1, three-dimensional reconstruction is carried out on an aneurysm; 2, a three-dimensional structure graph of the aneurysm clamp is designed through engineering design software according to the shape, size, position and determined operative route in an aneurysm model; 3, the three-dimensional structure graph is guided into 3D printing equipment, and the corresponding aneurysm clamp is prepared with the 3D printing technology. According to the provided method, the aneurysm clamp is designed according to practical situations of the aneurysm of a patient so that the manufactured aneurysm clamp fits the characteristics of the aneurysm of the patient, and clinic use requirements are met better.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically, to a method for preparing a personalized aneurysm clip and the aneurysm clip. Background technique [0002] Intracranial aneurysm (IA) is a cerebral hemangioma-like protrusion due to abnormal changes in local blood vessels. IA rupture accounts for more than 80% of spontaneous subarachnoid hemorrhage, and its morbidity, disability and mortality are high. The structure of intracranial arteries is different from that of extracranial arteries. It consists of three layers: the intima composed of endothelial cells, the media composed of smooth muscle cells, and the adventitia composed of collagen fibers. The well-developed internal elastic layer connects the intima with the media The membrane is separated, but lacks the outer elastic layer, or only a small amount of elastic fibers can be seen scattered between the outer membrane and the media. Therefore, the formation of IA may b...
