Detailed Description
The following is a detailed description of the present invention, which is described in detail with reference to the accompanying drawings and detailed description.
The utility model provides an external endotracheal tube device of bronchus plugging device can be under the condition of bronchofiberscope location with the accurate target bronchus that reaches of bronchus plugging device, in child's thoracic surgery, can also accomplish the operation smoothly, guarantees going on smoothly of operation, has also guaranteed patient's safety simultaneously.
Referring to fig. 1 and 3, an external endotracheal tube device for a bronchial occluder includes an endotracheal tube 1, and the endotracheal tube 1 is a water-sliding type reinforced tube. The tail end of the tracheal catheter 1 is fixed with a tracheal catheter cuff 2 which can control inflation and deflation. The side wall of the tracheal catheter 1 is provided with a catheter through hole 1-1 which is arranged along the length direction of the tracheal catheter 1. A connecting pipeline 4 is arranged in the through hole 1-1 of the tracheal catheter 1 in a penetrating way, the tail end of the connecting pipeline 4 is communicated with the cuff 2 of the tracheal catheter, and the front end of the cuff 2 of the tracheal catheter is connected with a cuff inflating valve 3. The cuff inflating valve 3 can control the inflation and deflation of the cuff 2 of the tracheal catheter.
Referring again to figure 2, the endotracheal tube cuff 2 has a hollow passage 5 therethrough, the hollow passage 5 being a substantially cylindrical passage, through the endotracheal tube cuff 2. In use, the trailing end of the bronchial stopper 6 is inserted into the hollow passage 5 of the endotracheal tube cuff 2. When the endotracheal tube cuff 2 is in an inflated state, the middle of the hollow passage 5 is expanded inwards, at this time, the hollow passage 5 is in an hourglass shape with two wide ends and a narrow middle, and the midpoint of the hollow passage 5 has a minimum diameter of 2mm to 2.5mm. When the endotracheal tube cuff 2 is in an uninflated state, the middle of the hollow passage 5 is constricted outwardly, with the smallest diameter at both ends of the hollow passage 5 being 3.5mm to 4mm. Because the outer diameter of the conventional bronchial occluder 6 conduit is 3.0mm, the size of the hollow channel 5 can ensure that the bronchial occluder 6 can easily pass through the hollow channel 5 when the tracheal catheter cuff 2 is in an uninflated state, and after the tracheal catheter cuff 2 is inflated, the hollow channel 5 can wrap and fix the bronchial occluder 6.
The tracheal catheter device with the external bronchial occluder is characterized in that a tracheal catheter cuff 2 with a nearly cylindrical hollow channel 5 in the middle is arranged at the tail end of a tracheal catheter 1, when the tracheal catheter device is used, a bronchial occluder 6 can penetrate through the hollow channel 5 in the tracheal catheter cuff 2, the bronchial occluder 6 is placed on the outer side of the tracheal catheter 1, the catheter of the bronchial occluder 6 can be connected with the tracheal catheter device with the external bronchial occluder, then the bronchial occluder 6 and the tracheal catheter device with the external bronchial occluder which are connected together are inserted at one time under a visible laryngoscope, the tracheal catheter 1 and the bronchial occluder 6 are adjusted to proper positions under the guide of a bronchofiberscope, the tracheal catheter cuff 2 of the tracheal catheter 1 is inflated after adjustment is completed, and the tracheal catheter device with the external bronchial occluder is fixed. The tracheal tube cuff 2 after inflation tightly wraps the 6 bronchi of the bronchial stopper, the bronchial stopper 6 is relatively fixed with the tracheal tube device for the external bronchial stopper, and the head end of the bronchial stopper 6 is fixed with the head end of the tracheal tube device for the external bronchial stopper, so that the fixing effect is enhanced.
Because the catheter of the bronchus blocker 6 is wrapped in the tracheal catheter cuff 2 and can move along the long axis direction of the tracheal catheter 1 under the operation of a doctor, an anaesthetist can cooperate with a chest surgeon to adjust the position of the bronchus blocker 6 under the visualization of a fiberbronchoscope in the operation process, and the bronchus blocker 6 is adjusted in the operation process, so that the blockage of one side lung is realized, and favorable conditions are provided for the smooth operation. Because the bronchus stopper 6 is fixed on the outer side of the tracheal catheter, the bronchofiberscope can also smoothly observe the bronchus conditions on two sides through the tracheal catheter 1 in the thoracic operation of the child, thereby ensuring the safety of the child patient. After the operation is finished, the bronchus blocking device 6 can be withdrawn from the hollow channel 5 in the middle of the cuff by loosening the tracheal catheter cuff 2, the double lung ventilation is carried out, the tracheal catheter device which can be used for the external arrangement of the bronchus blocking device does not need to be pulled out, the pulling-out of the tracheal catheter device which can be used for the external arrangement of the bronchus blocking device can be completed by an ICU doctor or pulled out after a patient is completely awake, and therefore potential safety hazards are further reduced.
The operation steps of this embodiment are as follows:
as shown in connection with fig. 3, when normal intubation;
1. selecting a tracheal catheter 1 and a bronchial occluder 6 with required models;
2. placing a bronchial occluder 6 into a hollow channel 5 in a tracheal catheter cuff 2;
3. inserting the tracheal catheter 1 and the bronchial stopper 6 into the trachea and the bronchial tube to be blocked;
4. adjusting the position of the bronchus stopper 6 under the guidance of a bronchofiberscope;
5. filling the tracheal catheter cuff 2 to fix the bronchial occluder 6;
6. the bronchus occluder 6 is filled with a cuff to occlude the bronchus at the operation side;
7. the position is confirmed again and fixed.
When the bronchial blocking device 6 needs to be adjusted or pulled out during or after the operation:
1. air in the tracheal catheter cuff 2 and the bronchial occluder 6 of the tracheal catheter 1 is pumped out;
2. adjusting or pulling out the bronchus stopper 6 under the guidance of a bronchofiberscope;
3. after adjustment, the tracheal catheter cuff 2 and the bronchus plugging device 6 of the tracheal catheter 1 are filled;
4. the position is determined and fixed.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but also to cover any modifications or equivalent changes made in the technical spirit of the present invention, which fall within the scope of the present invention.
