Description

Tracheal catheter special for upper gastrointestinal endoscopic surgery Technical Field The invention belongs to the technical field of medical appliances, and particularly relates to a special tracheal catheter for an upper gastrointestinal endoscopic surgery. Background The upper gastrointestinal endoscopic surgery is an operation performed by using a gastroscope or a duodenum to enter the upper gastrointestinal tract, and it is generally necessary to excise a lesion in the esophagus, stomach, duodenum, or the like and take out the lesion. The upper gastrointestinal endoscopic surgery usually requires tracheal intubation general anesthesia first, and a cuff is arranged at the distal end of the tracheal catheter, so that a respirator or an anesthesia machine can be ensured to control respiration, and the lung is isolated from the outside. When the tracheal catheter cuff is inflated, the tracheal catheter cuff can locally press the esophagus: 1. the lesion part of the esophagus requiring the operation may be pressed, and the depth of the adjustment after the cuff is deflated briefly may be improved. 2. If the lesion is in the lower esophageal segment, stomach or duodenum, a larger specimen may not pass through the compressed esophagus, and the cuff needs to be deflated briefly to allow the specimen to pass through and then re-inflate; 3. if the cuff is required to be deflated briefly, mucous blood in the mouth and the like can flow into the lung to cause aspiration pneumonia After the tracheal intubation is completed, the patient is in a left lateral position (left side down): 1. The oral secretion or the blood of the operation part can be deposited below (left side of a patient) along with gravity and possibly flow into the trachea, the suction holes of the tracheal catheter sucked on the conventional cuff are all on the wall of the catheter, the actual suction effect is poor, and the positions of the suction holes are difficult to judge after the tracheal intubation. 2. The tracheal catheter is required to be bent and fixed to one side during operation so as to avoid influencing the operation space (external force is usually used for traction, and the bending and fixing are not firm and are easy to fall off). 3. The endoscope and the tracheal catheter pass through the oral cavity, and friction can be generated during operation to cause the tracheal catheter to shift, so that the tracheal catheter is separated or the tracheal mucosa is damaged. The prior art has the following disadvantages: 1. The conventional tracheal catheter is easy to interfere with the operation and sample extraction in the upper gastrointestinal endoscopic surgery, and the cuff possibly presses the operation part and blocks the operation sample from being extracted from the esophagus after being inflated; 2. The existing double-cuff tracheal catheter is an air bag, has poor pressure conductivity, is not as sensitive as the accurate response of a water bag even if provided with a pressure gauge, and is not easy to judge when a specimen passes through the corresponding position of the cuff; 3. the prior double-cuff tracheal catheter cannot adjust the distance between cuffs; 4. the existing tracheal catheter suction can not effectively ensure the effect of sucking secretion or blood because the suction hole has a larger distance from the tracheal wall after the cuff is inflated; 5. None of the existing endotracheal tubes has a lubrication device for the upper gastrointestinal endoscope; 6. none of the existing endotracheal tubes has been improved according to the posture of the superior digestive endoscopy procedure, which is a patient's left lateral recumbent position with the endotracheal tube placed at the right lateral incision angle. Disclosure of Invention The invention aims to provide an endotracheal tube special for an upper gastrointestinal endoscopic surgery, which aims to solve the technical problems in the background technology. The tracheal catheter special for the upper gastrointestinal endoscopic surgery comprises an inner tube, wherein an outer tube capable of sliding up and down is sleeved outside the inner tube, the top end of the outer tube is fixedly connected with the inner tube through a fixing knob, a breathing machine joint is arranged at the top end of the inner tube, an inner tube water bag is arranged at the bottom of the inner tube, an inner tube suction hole is formed in one side of the inner tube water bag, a Murphy hole is formed in the position, below the inner tube water bag, of the bottom end of the inner tube, an inner tube water injection pump and an inner tube suction connector are respectively arranged on the top end side wall of the inner tube, an inner tube pressure gauge is arranged on the inner tube suction connector, an inner tube one-way flap is arranged on the top end side wall of the outer tube, an outer tube water injection pump, an outer tube suction connector and a lubricant injection tub
