Upper urinary tract integrated support drainage catheter

Abstract

The invention discloses an upper urinary tract integrated support drainage catheter and relates to medical instruments used for urinary tract drainage. The upper urinary tract integrated support drainage catheter comprises a fistulization tube and a connector. The fistulization tube comprises a short thin tube part in a pigtail coil shape, and a long thick tube part for drainage, wherein the long thick tube part is connected with the thin tube part. The joint of the thin tube part and the thick tube part is conical. The tail end can be bent, the long and thin end can be arranged in a ureter whole section, and the tail end is located in the urinary bladder. When the fistulization tube is pulled out, after the thick part of the fistulization tube leaves skin, the tail end of the long and thin part is still located in a collecting system. The upper urinary tract integrated support drainage catheter can drain an upper urinary tract, and the thin part is equivalent to a double J tube; during channel bleeding, bleeding stopping can be achieved through inflation air bags and traction compression; a drainage catheter can be slowly pulled out after a patient suffering from percutaneous renal stone breaking is in anesthetic awareness; in addition, the drainage tube can be tightly connected with the connector through a stepped structure, and no disengagement is likely to happen.

Description

technical field [0001] The invention relates to a medical device used for drainage of urinary tract, in particular to an integrated stent drainage catheter for upper urinary tract. Background technique [0002] In the current field of surgery, minimally invasive, laparoscopic or open surgery is used to establish a percutaneous renal channel. After surgical treatment of upper urinary tract diseases, especially upper urinary tract stones, nephrostomy tubes and ureteral stent drainage tubes are usually routinely placed. [0003] The characteristics of the existing nephrostomy tube: the overall thickness is uniform; one end is located in the renal pelvis, and the other end is led out of the body, and cannot be twisted; the section of the nephrostomy tube in the renal pelvis only has a drainage effect and has no compression and hemostasis; The oppressive force of the channel is instantly relieved; once it is removed, it is difficult to re-indwell along the ostomy channel immediat...
