Description
Technical field
Exempt to suture pancreas Surgical healing the utility model is related to medical operating articles for use technical field more particularly to a kind of 3D printing
Stent.
Background technology
Tradition opens abdomen pancreatoduodenectomy operation complexity, and operation wound is big, and biliary enteric anastomosis, Pancreaticoenterostomy are
The committed step of pancreatoduodenectomy, courage intestines are kissed caused by Cholangio- jejunostomy mouth or (and pancreas intestinal anastomotic stoma) healing be not complete
Heal up fistula, Pancreaticojejunostomy is postoperative common severe complication, and general incidence is 5~20%, and Pancreaticojejunostomy is dead
Rate is died up to 20~40%, and medical expense is expensive.
Biliary enteric anastomosis, the Pancreaticoenterostomy of clinical practice at present are established with suturing, on the basis of knotting, most preferable
The mode of reconstruction of digestive tract be to have a kind of methods of anastomosis, these and the relevant operation of suture can be exempted.Suture nature has pin
The defects of tear of eye, the elasticity, institutional framework that knot, the extension of operating time.Using a kind of stent, coincide two will be intended
End connects and can fix after being each inserted in, and the connection of two broken ends of fractured bone self-growths so can both exempt suture, no matter avoid to abdominal cavity
Mirror or Leonardo da Vinci, which exist, is difficult to the technical bottleneck overcome, and the unobstructed of previous anastomotic is ensure that further through stent, avoid because
Complication caused by previous anastomotic oedema or identical defect are possible.Many trials have also been made in previous research in this respect, still
So far there are no it is molding can be with the product of clinical practice, reason is Cholangio- jejunostomy, pancreas Surgical healing unlike gastrointestinal anastomosis, stomach and intestine
It coincide because tissue plasticity is strong, previous anastomotic size is relatively fixed, previous anastomotic is big, therefore clinical commonly used stapler；And
Biliary tract, the shape and size of ductus pancreaticus and bore, because disease property, stadium difference are widely different, and ductus pancreaticus, bile duct plasticity
Difference, caliber is small, therefore, there is anastomosis ring or stapler that the bore that fixing mould is produced is consistent as gastrointestinal stapler,
It is not appropriate for clinic.Cross it is thick it is easily made to strut excessively and influence Tissue Blood confession, cross detailed rules and regulations can cause it is fixed loosely.
