Description
Technical Field
The utility model relates to a medical treatment air flue intubation device technical field, especially a retrograde motion tractive intubation device of difficult air flue.
Background
In clinical anesthesia or rescue of critical patients, especially when the tracheal catheter is difficult to be inserted into the trachea in difficult airways, the trachea is required to be inserted through the larynx in a retrograde manner. Firstly, the needle is punctured by the cricothyroid membrane, a silk thread with a guiding function is placed in the glottis direction, and the silk thread is pulled out by the oral cavity or the nasal cavity, and then the tracheal catheter is guided to enter the trachea.
At present, according to different guide methods, the clinical application can be divided into a classical retrograde guided tracheal intubation method, a retrograde guided traction tracheal intubation method, a retrograde guide wire and antegrade guide tube combined tracheal intubation method. The method is simple to operate and easy to master, and the required instruments are common and easy to obtain. The guiding thread used in the above procedures is generally an epidural catheter or a guiding thread steel wire for central venipuncture. The epidural catheter has the advantages of being relatively soft and capable of being deformed randomly. When the tracheal catheter enters the glottis and continues to go deep along the trachea through the level of the cricothyroid membrane, the epidural catheter easily goes into the trachea along with the penetration of the tracheal catheter. When the guide wire is pulled out, the tracheal catheter cannot be easily and accidentally pulled out. But the epidural catheter has the disadvantage that the epidural catheter is thin and soft. Poor guidance is often encountered when the epidural catheter is curled in the trachea and cannot reach the oral cavity through the glottis to prolong the intubation. Compared with an epidural catheter, the guide threaded steel wire for central venipuncture has certain elasticity and toughness, is not easy to kink and easily penetrate out of a glottis, and the J-shaped end has little damage to an airway. However, the guide thread steel wire for central venipuncture has the defect of failure in intubation because the tracheal catheter is difficult to be horizontally continued to the far end through the cricothyroid membrane due to the toughness of the guide thread steel wire.
In terms of operation, the classical retrograde guided intubation method has the disadvantage that the outer diameter of a guide wire is obviously smaller than the inner diameter of a tracheal catheter when the intubation is conducted in a retrograde guided mode, so that the front end of the tracheal catheter is easily blocked by an epiglottis due to overlarge movement of the mouth of the tracheal catheter, and the epiglottis valley or anterior vocal cord combination and the like are difficult to enter the trachea through the epiglottis and the glottis. Even if the antegrade guiding method is combined, the external diameter and the hardness of the guiding wire are increased by inserting the guiding wire into the antegrade guiding pipe, the front end of the tracheal catheter is still easily blocked by the epiglottis, and the epiglottis valley or the anterior vocal cord combination and the like are difficult to enter the trachea through the epiglottis and the glottis. Even multiple operations may result in trauma bleeding at the throat, epiglottis, vocal cords, etc. And because the tube is placed twice, the operation time is prolonged, and the time waste is caused to the rescue of the patient.
In the existing retrograde traction intubation device with difficult airway, a puncture needle cannot be fixed during puncture operation, in addition, a guide wire needs to be drawn back and forth during leading out, and the end part of a U-shaped structure of the guide wire is easy to scratch the trachea and other structures of a patient.
