A 3D printed degradable bracket for correcting vaginal deformity and its manufacturing method

Abstract

The invention provides a 3D printing biodegradable stent used for correcting vagina malformation and a manufacturing method of the 3D printing biodegradable stent. The biodegradable stent comprises astent main body designed according to image data of a patient, wherein the stent main body is a hollow pipeline with two open ends, holes are formed in the surface of the stent main body, and flangesare arranged at the open positions of two ends of the stent main body; a groove is arranged at one side of the stent main body. The manufacturing method comprises the following steps: carrying out medical image scanning on the affected part of the patient; carrying out three-dimensional reconstruction and the design of the individual porous stent in a computer, and processing the designed stent byadopting 3D printing slicing software, thus obtaining the information of each section layer; and importing the information of each section layer after slicing into a 3D printer, and carrying out printing by adopting a degradable bioactive material, thus obtaining the stent. According to the 3D printing biodegradable stent and the manufacturing method, the trauma caused to the patient can be reduced, meanwhile, somatic cells can grow into the stent along with the passage of time, then a natural cavity is formed, moreover, the stent degrades naturally, and therefore, the risk and injuries of the secondary surgery are avoided.

Description

technical field [0001] The invention relates to the technical field of degradable stents, in particular to a 3D printed degradable stent for correcting vaginal deformities and a manufacturing method thereof. Background technique [0002] Vaginal malformation is a common dysplasia disease of female genital organs, mostly caused by congenital malformation, common types include vaginal atresia or stenosis, vaginal septum, vaginal oblique septum, and vaginal mediastinum. Clinically, once a vaginal deformity is diagnosed, especially vaginal atresia, vaginoplasty is required immediately for vaginal reconstruction. The incidence rate of congenital absence of vagina or vaginal atresia is about 1:4000-1:5000, and the incidence rate is relatively high. Traditional surgical methods include amniotic vaginoplasty, peritoneal vaginoplasty, intestinal tube vaginoplasty, etc., and skin flap vaginoplasty These surgical methods need to cut tissues from different parts of the patient's body f...

Problems solved by technology

The incidence rate of congenital absence of vagina or vaginal atresia is about 1:4000-1:5000, and the incidence rate is relatively high. Traditional surgical methods include amniotic vaginoplasty, peritoneal vaginoplasty, intestinal tube vaginoplasty, etc., and skin flap vaginoplasty These surgical methods need to cut tissues from different parts of the patient's body for displacement repair. The wound area is large, and in order to prevent regeneration stenosis and scar contracture after the operation, the mold needs to be placed for a long time, which causes a lot of inconvenience to the patient. affected to varying degrees
