Description
Technical Field
The invention relates to the technical field of surgical anastomosis, in particular to a 3D printing suture-free biliary-enteric anastomosis stent for hepatobiliary-pancreatic surgery.
Background
The traditional laparotomy-pancreaticoduodenectomy is complex in operation and large in operation wound, choleenteroanastomosis and pancreaticoduodenectomy are key steps of the pancreaticoduodenectomy, and choleenteroanastomosis fistula and pancreaticoenteroanastomosis fistula caused by incomplete healing of a choleenteroanastomosis stoma or (and a pancreaticoenteroanastomosis stoma) are common serious complications after the operation, the common occurrence rate is 5-20%, the death rate of the pancreaticoduodenostomy fistula can reach 20-40%, and the treatment cost is high. At present, the choleenterostomy and the pancreaticoenterostomy which are clinically applied are established, sutured and knotted, and are most ideal
The reconstruction of the digestive tract in question is an anastomosis that eliminates these suturing-related operations. The suture naturally has the defects of needle eyes, knotted tightness, tearing of tissue structures, prolonged operation time and the like. The bracket is utilized, the two ends to be anastomosed are respectively sleeved and then connected and can be fixed, and the two broken ends are automatically grown and connected, so that the suture can be avoided, the technical bottleneck which is difficult to overcome in both laparoscope and DaVinci can be avoided, the smoothness of an anastomotic stoma can be ensured through the bracket, and the complication possibly caused by edema of the anastomotic stoma or anastomotic defect can be avoided. In the prior art, many attempts are made in this respect, but no formed product which can be clinically applied exists so far, because the cholangiointestinal anastomosis and the pancreaticointestinal anastomosis are not like the gastrointestinal anastomosis, and the gastrointestinal anastomosis is generally applied to clinic because the tissue plasticity is strong, the size of an anastomosis is relatively fixed, and the size of the anastomosis is large; the shapes, sizes and calibers of the biliary tract and the pancreatic duct are greatly different according to the nature and disease period of diseases, and the pancreatic duct and the bile duct have poor plasticity and small calibers, so that an anastomotic ring or an anastomat with consistent calibers, which is produced by a fixed mould like a gastrointestinal anastomat, is not suitable for clinical application. Too thick can cause excessive distraction and affect the blood supply to the tissue, while too thin can cause poor fixation.
