With the rise of the therapeutic level under the digestive endoscopy, endoscopic Retrograde Cholangiopancreatography (ERCP) has gradually become a routine operation of the digestive system, and about 80% of patients with such operation need to place a nasal bile duct after the operation, and after the nasal bile duct is placed in place, the tail end of the nasal bile duct needs to be transferred from the throat to the nasal cavity and then fixed.

At present, a guide wire bent into a lasso shape is usually stretched into the back wall of the pharynx from the throat of a patient, then a hose is inserted into the back wall of the pharynx from the nasal cavity, and then the lasso guide wire is pulled out, and the hose is taken out of the throat, at this time, the tail end of the hose in the throat and the tail end of a nasal bile duct are butted into a pipeline, and then the hose is pulled out, so that the nasal bile duct is pulled out along.

Wherein, the flexible tube 1 is suitable for inserting into the throat from the nasal cavity, one end of the flexible tube 1 inserted into the throat is suitable for connecting with the nasal bile duct, for example, the flexible tube 1 can be inserted into the nasal bile duct, at least part of the flexible tube 1 inserted into the throat is a magnetic tube, in other words, the flexible tube 1 can be integrally constructed into a magnetic tube, or only the part inserted into the throat is constructed into a magnetic tube.

At least part of the hose taking-out member 2 is a magnetic attraction member, and the hose taking-out member 2 is suitable for being stretched into the throat from the oral cavity to be in magnetic attraction fit with the casing hose 1, and the casing hose 1 is taken out of the throat, for example, the hose taking-out member 2 can be a magnetic attraction member as a whole, or can be a magnetic attraction member only at the part stretching into the throat, so that the magnetic attraction fit with the casing hose 1 is facilitated.

After Endoscopic Retrograde Cholangiopancreatography (ERCP) has been performed on the patient and the nasal bile duct is placed in place, the end of the nasal bile duct is located in the oral cavity, at which time the nasal bile duct can be transferred from the oral cavity to the nasal cavity for fixation using the nasal bile duct trepanning device 100 of the present embodiment. The specific operation method is as follows: an operator inserts one end of the sleeving hose 1 into the back pharyngeal wall from the nasal cavity of a patient, the hose taking-out piece 2 stretches into the back pharyngeal wall from the oral cavity of the patient, the hose taking-out piece 2 is in magnetic attraction fit with the sleeving hose 1, then the hose taking-out piece 2 is pulled out from the oral cavity part, and at the moment, the hose taking-out piece 2 can bring out the sleeving hose 1; the tail end of the sleeving hose 1 in the oral cavity and the tail end of the nasal bile duct are mutually connected, for example, are spliced to form a pipeline, and then one end of the sleeving hose 1 which does not enter the nasal cavity is pulled, so that one end of the sleeving hose 1 which enters the throat returns to the nasal cavity from the throat in the opposite direction and exits, the nasal bile duct can be transferred from the oral cavity to the nasal cavity, and finally the nasal bile duct is fixed.

According to the naso-biliary tract withdrawing device 100 of the embodiment of the utility model, compared with the method of drawing out the hose by using the sleeve-lock-shaped guide wire to extend into the oral cavity in the related art, since the withdrawing hose 1 and the hose withdrawing member 2 are in magnetic attraction fit, even under the condition of not having a good operation visual field, an operator can efficiently and quickly determine the position of the withdrawing hose 1 by using the hose withdrawing member 2 and draw out the hose from the throat, thereby being beneficial to reducing the operation times and improving the operation efficiency, reducing the damage to the oral cavity and pharyngeal mucosa, relieving the pain of a patient, and avoiding the occurrence of the conditions of naso-biliary tract displacement, operation failure and the like caused by discomfort, body movement, non-fit and the like of the patient.
