Pancreaticobiliary duct combined stent pipe device with magnetic ring for use in pancreatoduodenectomy

Abstract

The invention discloses a pancreaticobiliary duct combined stent pipe device with a magnetic ring for use in pancreatoduodenectomy, which comprises a combined stent pipe, and a son magnetic ring and a mother magnetic ring, which are matched with the combined stent pipe. When the pancreaticobiliary duct combined stent pipe device with the magnetic ring for use in pancreatoduodenectomy is used to accomplish the cholangioenterostomy, namely the combined stent pipe with the son and mother magnetic rings is implanted to accomplish binding pancreaticojejunostomy together with biogum, the bile and pancreatic juice can be isolated completely, the pancreatic juice and the bile are activated, the surgical operation is greatly simplified, the operation difficulty is lower, the operation is simple and easy to implement, and the probability of infection of the wound is lowered; in addition, related complications caused by stitching are avoided, operation time can be reduced obviously, the hospitalstay of a patient is reduced, corresponding medical cost is reduced, the after-operation pipe detention time is reduced effectively, the life quality of the patient after the operation is improved, and the recovery after the operation is promoted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pancreaticobiliary combined stent pipe device with a magnetic ring for pancreatoduodenectomy. Background technique [0002] Pancreaticoduodenectomy is one of the most invasive surgeries in the field of surgery, with a large scope of surgery involving many organs, and a high proportion of postoperative complications. Pancreaticojejunostomy leakage is one of the most common and serious complications after pancreaticoduodenectomy. It is difficult to treat, has poor prognosis and high mortality. In recent years, Peng's bundled pancreaticojejunostomy device and double-layer continuous sleeve anastomosis device have appeared successively in China for pancreatic leakage, while Imaizumi surgical device and its improved devices are generally used abroad, which play a significant role in preventing pancreatic leakage after operation. curative effect. However, the ab...

AI Technical Summary

Problems solved by technology

[0003] 1. The scope of use is large, involving many organs, resulting in longer operation time, increasing the chance of surgical infection, and slower recovery of patients after surgery;

[0004] 2. The anastomosis is difficult, and the operator needs to have good suture anastomosis skills, and the resistance to popularization in the surgical field is high;

[0005] 3. The incidence of anastomotic leakage is high and the complications are serious when using these devices;

[0006] 4. The hospitalization time of patients using these devices is longer, and the stay time of the tubes, especially the pancreatic duct stent tubes, is longer, which increases medical expenses and greatly affects the quality of life after surgery
