Intranasal cyst external drainage tube with water bag for ultrasonic endoscope

Abstract

The invention belongs to the technical field of drainage tubes, and particularly relates to a nasal cyst external drainage tube with a water bag for an ultrasonic endoscope, which comprises a treatment type ultrasonic endoscope, a puncture needle, a guide wire, a drainage tube and a bag membrane, when a nasal biliary drainage tube special for ERCP is used for pancreatic pseudocyst drainage, due to the fact that no corresponding fixing device exists, the nasal cyst drainage tube often shifts and / or falls off in the early stage, and treatment fails; therefore, through the capsule membrane arranged on the outer wall of the drainage tube main body, after the tail end of the drainage tube main body is placed into a cyst cavity through a guide wire, the capsule membrane is filled with gas or liquid, so that the capsule membrane is filled up, the filled capsule membrane is attached to the inner wall of a cyst, and relatively strong tension is exerted on the wall of the cyst; the fixing effect of the tail end of the drainage tube body at the cyst part is enhanced, the drainage tube body is prevented from being disengaged, and therefore the stability of the pancreatic pseudocyst drainage process is maintained, drainage failure is avoided, and the treatment effect of the nasal cyst outer drainage tube is improved.

Description

technical field [0001] The invention belongs to the technical field of drainage tubes, in particular to an external drainage tube for transnasal cysts with a water bladder for ultrasonic endoscopy. Background technique [0002] At present, with the continuous development of endoscopic ultrasonography and the continuous improvement of its accessories, endoscopic ultrasound-guided drainage of pancreatic pseudocysts has become an important measure for the treatment of pancreatic pseudocysts. Compared with traditional laparotomy, this technique has the advantages of less trauma, high safety factor, and faster recovery. Under the real-time observation of endoscopic ultrasonography, it is possible to judge whether the lesion is a true cyst of the pancreas or a pseudocyst of the pancreas; whether the pseudocyst of the pancreas is connected with the pancreatic duct, whether there is a pancreatic fistula, and the puncture and drainage of the pseudocyst of the pancreas can be performe...

Problems solved by technology

Most of the nasal and bile drainage tubes used in clinical practice are straight tubes or single pigtail drainage tubes. Both types of drainage tubes may shift and prolapse by themselves, resulting in drainage failure.
