Embodiment 1

[0058] A method for making a microcatheter shaping auxiliary support for aneurysm interventional surgery, which is used to quickly shape the microcatheter intervening in cerebral blood vessels by steam, so as to obtain a microcatheter suitable for the shape of the lesion aneurysm and blood vessels and to intervene in the artery Carry out endovascular embolization therapy for the tumor; the making of the microcatheter shaping auxiliary brace specifically includes the following steps:

[0059] Step S01, using CT angiography scan to obtain CT image data package A01 of lesion vessels and aneurysms;

[0060] Step S02, importing the CT image data package A01 obtained in step S01 into the medical modeling software that can recognize the CT image data package A01 and obtaining the 3D mathematical model data package B01 corresponding to the parameters of A01 and saved in a common CAD format;

[0061] Step S03, edit the 3D mathematical model data package B01 obtained in step S02, and ob...

Embodiment 2

[0067] As a preferred solution of the present invention, on the basis of Example 1, the contrast agent used for CT angiography in step S01 is iodine reagent or carbon dioxide as a contrast agent; the operation steps of angiography are as follows: When the drug is injected into the patient's body, or immediately use CT contrast-enhanced scan or plain scan CT to scan the lesion to obtain the CT image data package A01.

[0068] After entering the body, the quantity and distribution of the contrast agent in various parts show certain density and shape differences according to the characteristics of the vascular structure of the lesion. Clinical practice has fully proved that enhanced scanning can significantly improve the resolution and diagnostic accuracy of CT examination of certain organs. Take cranial CT examination as an example, the accuracy rate of plain scan CT is 82%, and the accuracy rate of enhanced scan rises to 92%-95%. It is suitable for the detection of large blood ...

Embodiment 3

[0070] As a preferred solution of the present invention, on the basis of the above-mentioned embodiment 1 or embodiment 2, the medical modeling software described in the step S02 is Mimics or Arigin3D. The following takes Mimics as an example to operate the steps:

[0071] The first step is to import the above-mentioned CT image data package A01 into Mimics, observe and adjust the threshold value of the original CT affecting data package A01 through Mimics;

[0072] The second step is to obtain a clear three-dimensional image of angiography according to the adjustment of the threshold, select the required image content, and determine all the angiography images that need to be followed by modeling;

[0073] The third step is to fill all the holes or missing places in all the selected angiographic images to avoid defects in the model caused by threshold setting errors;

[0074] The fourth step is to build a 3D model. Usually, the bitmap of the 3D graphics can be generated by ru...

Abstract

The invention belongs to the technical field of medical instruments, and provides an auxiliary brace for shaping an aneurysm interventional micro-catheter; The auxiliary brace can be used for solvingthe technical problems of the prior art that the treatment of aneurysms by microcatheter interventional embolization will bring the difficulties in shaping microcatheters, inaccurate shaping, the success of microcatheter shaping cannot be guaranteed relying on the doctor's subjective judgment and prolonging the operation time, surgical failure could be caused. At the same time, the present invention also provides a method for manufacturing the above-mentioned microcatheter shaping auxiliary brace, according to different structures of different patients and blood vessels. An auxiliary brace consistent with the vascular structure of the patient's lesion was made and obtained. Through the definition and restraint of the auxiliary brace, the conventional high-temperature fumigation can be usedfor precise molding at one time, which greatly improves the accuracy of shaping the microcavity. One molding can save a lot of pre-operative preparation time, avoiding the problem of repeated shapingduring surgery and delaying the operation time.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to the field of auxiliary medical devices for aneurysm treatment by interventional surgery, in particular to a microcatheter shaping auxiliary brace for aneurysm interventional surgery and a manufacturing method thereof. Background technique [0002] Aneurysms generally refer to intracranial aneurysms, which are localized abnormal enlargements of cerebral arteries, saccular aneurysms are the most common, and others include fusiform aneurysms, dissecting aneurysms, and pseudoaneurysms. Intracranial aneurysms are the most common cause of spontaneous subarachnoid hemorrhage (SAH). [0003] In the prior art, the treatment of aneurysm can be divided into early operation (6-96 hours after SAH) and late operation (more than 10-14 days) according to the operation time. 4 to 10 days after SAH, the effect of surgery is poor. Surgical methods include direct surgical clipping of aneur...
