Problems solved by technology

However, the titanium alloy and other materials currently used in the preparation of precision vascular stents are not only expensive, but also have a long production cycle, and the selectivity of the stent structure is very narrow. At present, most of the vascular stents in my country are imported from abroad. High costs deprive many patients of effective treatment
Moreover, each patient cannot customize a suitable vascular stent according to their own needs, and the success rate of the operation and the recovery rate of the patient cannot be effectively guaranteed. Therefore, the use of 3D printing technology to prepare artificial vascular stents has broad application prospects.

Embodiment 1

[0037] A method for preparing a stent for the inner wall of a blood vessel using 3D printing technology, comprising the following steps:

[0038] (1) Use a CT tomography scanner to scan the part of the human blood vessel that needs to be manufactured with a stent on the inner wall of the blood vessel, and initially obtain the mcs file of the 3D model diagram of the part where the stent needs to be built.

[0039] (2) Use AutoCAD and Auto3DsMAX to draw the stent on the inner wall of the blood vessel in the obtained model drawing file. The control error range of the shape structure is 5%, and the drawing is carried out according to the set structure, and the following is obtained: figure 1 and figure 2 The displayed 3D model file diagram of the vascular inner wall stent is then converted to STL format by software and exported to the SD card for future use.

[0040] (3) Install the corresponding software of the 3D printer on the computer, use the software of the 3D printer to r...

Abstract

The invention discloses a method for utilizing a 3D printing technology to manufacture an intravascular inner wall stent and a product thereof. The method comprises the steps that a human body scanning device is utilized to scan the human body blood vessel part of the intravascular inner wall stent to be manufactured so as to preliminarily obtain a 3D model figure of the part needing the stent; computer drawing software is utilized to draw the rudiment of the intravascular inner wall stent needed to be erected in the obtained 3D model figure, then the stent rudiment is isolated and taken from the model figure, then finishing processing is performed, and finally the stent rudiment is converted into a file format which can identified by a 3D printer to be output; 3D printer software is utilized to read and identify a file as a main body of a model; then, the software is utilized to perform model stenting body establishment so as to obtain a model section file to be printed; a main body material and a supporting body material are loaded into two consumable chambers of the 3D printer, printing parameters are arranged for printing, then the established supporting body is removed to obtain the intravascular inner wall stent. The stent is low in cost and is more suitable for an individual.

Description

technical field [0001] The invention belongs to the technical field of medical device preparation, and in particular relates to a method for preparing a vascular inner wall stent by using 3D printing technology and a product thereof. Background technique [0002] Nowadays, the rapid development of the 3D printing industry has attracted the attention and attention of all walks of life. This molding technology is to directly input the 3D model file into the machine and then perform layer-by-layer printing and superposition molding. Theoretically, it can ignore any complicated structure and directly form it at one time. , There is also a wide range of choices for the materials used, especially in the medical field, this advantage is particularly obvious. According to the individual conditions of different patients, it can use three-dimensional models and different materials to artificially manufacture complex organs, bone tissues, blood vessel structures, etc., and has excellen...
