A catheter drainage device for biliary and pancreatic surgery

Abstract

The invention discloses a catheter drainage device for biliary and pancreatic surgery, comprising a T-shaped tube, the T-shaped tube is composed of a bile fluid indwelling tube and a concave arc-shaped plate in the middle, and the upper end of the bile fluid indwelling tube is connected with the arc The middle part of the lower side of the shaped plate is fixedly connected, the inside of the bile indwelling tube is sleeved with a pancreatic duct, the lower end of the pancreatic duct runs through the side wall of the shunt valve and extends to the outside, and the upper end of the pancreatic duct runs through the bile indwelling tube and the arc in turn. The side wall of the plate extends to the outside. The invention connects the pancreatic duct to the inside of the bile indwelling tube to realize the two-way merging of the pancreatic duct and the bile indwelling tube. The increased incidence of leakage tube complications caused by the abdominal drainage tube is placed at the biliary-enteric anastomosis through the arc-shaped plate of the T-tube, and then the T-tube can be stably fixed in the patient's body, avoiding the occurrence of falling off .

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tube placement and drainage device for biliary and pancreatic surgery. Background technique [0002] In medicine, during pancreaticoduodenectomy or some traumatic operations, bile and pancreatic juice will flow out and accumulate at the biliary-enteric anastomosis and pancreatico-enteric anastomosis, which will easily increase the tension of the anastomosis, which is not conducive to The recovery of the patient, and the pancreatic juice is highly corrosive, and it is easy to corrode the patient's intestinal tract. At this time, it is necessary to drain the bile and pancreatic juice at the same time, and then avoid the accumulation of the bile and pancreatic juice at the anastomotic site to cause complications; now Some drainage methods for bile juice and pancreatic juice are generally carried out separately, that is, two holes are opened in the abdominal wall of the pat...

Problems solved by technology

[0002] In medicine, during pancreaticoduodenectomy or some traumatic operations, bile and pancreatic juice will flow out and accumulate at the biliary-enteric anastomosis and pancreatico-enteric anastomosis, which will easily increase the tension of the anastomosis, which is not conducive to The recovery of the patient, and the pancreatic juice is highly corrosive, and it is easy to corrode the patient's intestinal tract. At this time, it is necessary to drain the bile and pancreatic juice at the same time, and then avoid the accumulation of the bile and pancreatic juice at the anastomotic site to cause complications; now Some drainage methods for bile juice and pancreatic juice are generally carried out separately, that is, two holes are opened in the abdominal wall of the patient, and two drainage tubes are inserted from the two holes to the biliary-enteric anastomosis and the pancreas. Drainage will lead to an increase in the number of wounds on the patient's abdominal wall, which is not conducive to the patient's recovery; and there is a potential risk of leakage of pancreatic juice from the intestinal tract, which is prone to complications; the insertion end of the existing drainage tube is mostly an ordinary straight tube , the lack of support fixed in the patient's body, and then it is easy for the drainage tube to come out of the patient's body by itself, which reduces the drainage effect. Therefore, we propose a catheter drainage device for biliary and pancreatic surgery
