PERCUTANEOUS ACCESS CATHETER FOR INSERTION OF DRAINAGE TUBE

摘要

The present invention relates to a percutaneous access catheter (PAC) for the insertion of a drainage tube, and the PAC comprises an inner catheter and an outer catheter and is inserted before inserting a drainage tube into the biliary tract or a nephrostomy in order to perform percutaneous transhepatic biliary drainage or percutaneous nephrostomy, wherein a bent part is formed at the outer catheter by bending one end part of a straight line part of the catheter such that the outer catheter can smoothly go over from the biliary tract or a nephrostomy of one side to the biliary tract or a nephrostomy of the other side along a guide iron wire inserted into the biliary tract or a nephrostomy, and at least one side hole capable of discharging contaminants is formed at the bent part. There are an effect of reducing the inconvenience or time and cost of using an additional catheter used if there is a bent or a stricture at the biliary tract or a nephrostomy when performing percutaneous transhepatic biliary drainage or percutaneous nephrostomy, and an effect of smoothly draining contaminants such as contaminated bile.
