Catheter drainage device for biliary and pancreatic surgery

Abstract

The invention discloses a catheter drainage device for biliary and pancreatic surgery. The catheter drainage device comprises T-shaped catheter that is made of a bile indwelling catheter and a curvedplate having concave middle part. The upper end of the bile indwelling catheter is fixedly connected with the middle part of the lower side of the curved plate. A pancreatic catheter is sleeved on theinterior of the bile indwelling catheter. The lower end of the pancreatic catheter penetrates through side wall of a diverter valve and extends to outside of the diverter valve. The upper end of thepancreatic catheter successively penetrates through the bile indwelling catheter and the side wall of the curved plate and extends to outside of the curved plate. According to the invention, the pancreatic catheter is sleeved on the interior of the bile indwelling catheter to combine the pancreatic catheter and the bile indwelling catheter into a whole, thereby reducing amount of punctures on abdominal wall of a patient and reducing incidence of leakage complications caused by placement of an abdominal drainage catheter. The curved plate of the T-shaped catheter is placed at a bilioenteric anastomosis, and then the T-shaped catheter can be stably fixed in the body of the patient, thereby avoiding occurrence of shedding phenomenon.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a catheter drainage device for biliary and pancreatic surgery. Background technique [0002] In medicine, during pancreaticoduodenectomy or some trauma operations, bile and pancreatic juice will flow out and accumulate at the biliary-enteric anastomosis and pancreatico-enteric anastomosis after surgery, which will then easily increase the tension of the anastomosis, which is not conducive to Rehabilitation of the patient, and the pancreatic juice is highly corrosive, which is likely to corrode the patient's intestines. At this time, bile and pancreatic juice need to be drained out at the same time, so as to avoid the accumulation of bile and pancreatic juice at the anastomosis and cause complications; Some drainage methods for bile and pancreatic juice are generally performed separately, that is, two holes are made in the patient's abdominal wall, and two drainage tubes are ...

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
