Description

Technical Field

[0001] The utility model relates to the technical field of fiberoptic bronchoscopes, in particular to a multi-purpose fiberoptic bronchoscope. Background Art

[0002] Fiberoptic bronchoscopes are widely used in ICUs, mainly for diagnosis and treatment. Since the esophagus is a muscular organ without cartilage support, and the fiberoptic bronchoscope needs to be connected to negative pressure when used, it cannot be observed after being inserted into the esophagus. Therefore, it is not suitable for early warning assessment of acute early lesions of the stomach and intestines, and cannot identify bleeding lesions at an early stage.

[0003] For example, patients in the ICU often need to have a tracheal tube inserted into the trachea, which can easily lead to the occurrence of tracheoesophageal fistula. This is because after the tracheal tube is inserted, the balloon needs to be filled to ensure that there will be no leakage during mechanical ventilation. However, when the tracheal tube is left in place for a long time, the tracheal wall is compressed by the balloon and damaged, or even ruptured. Since there are cartilage rings on the front wall of the trachea and no cartilage rings on the back wall of the trachea, it is very easy to damage the back wall of the trachea to form a fistula. Generally, esophageal fistulas are prone to occur when the tracheal tube is left in place for more than one month. When an esophageal fistula is formed, gas will leak out of the fistula into the esophagus, and then part of it will be discharged through the mouth, and the other part will go down into the stomach, which will cause the ventilator to prompt a leak. The gas that enters the esophagus overflows through the mouth, and the patient's mouth will have abnormal sounds. The gas that enters the esophagus and goes down into the gastrointestinal tract will cause obvious gastrointestinal flatulence. If a fiberoptic bronchoscope is used for observation, when the fiberoptic bronchoscope enters the endotracheal tube and reaches the position where the fistula may occur, the fiberoptic bronchoscope cannot observe the fistula through the wall of the endotracheal tube due to the obstruction of the endotracheal tube wall and the airbag; when the fiberoptic bronchoscope is used after the endotracheal tube is removed, the fistula is closed due to the loss of support from the airbag, and the fistula cannot be observed through the fiberoptic bronchoscope.

[0004] In the current existing technology, gastroscopy is usually used to check whether a tracheoesophageal fistula has been formed. If the air bag crushes the tracheal tube to form a tracheoesophageal fistula, the gastroscope can easily find the fistula, which is manifested by the white air bag breaking through the anterior wall of the esophagus. However, gastroscopy is not widely used in ICUs, and the existing bronchoscope cannot meet the use needs; in addition, when a fistula is found after examination, hemostasis treatment is required, usually by inserting a hemostatic guidewire, but its operation is very inconvenient.

[0005] Therefore, we propose a multi-purpose fiberoptic bronchoscope to solve the above-mentioned problems.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field.

The end of the first trachea 2011 is mounted on the mirror body 101 and is located at the ventilation tube 102, which is used to communicate with the fiberoptic bronchoscope 1. The two second trachea 2012 are respectively used to introduce an oxygen source and a negative pressure source, which is convenient for switching the passage when the fiberoptic bronchoscope 1 is used for different purposes. The first trachea 2011 is provided with a connecting assembly 202; the connecting assembly 202 includes The outer shell 2021, the transmission structure 2022 and the guide rod 2023; the outer shell 2021 is provided with ventilation holes on both sides and the bottom, and the ventilation holes on the two sides correspond to the second air pipe 2012 respectively, and the ventilation holes on the bottom correspond to the first air pipe 2011; the transmission structure 2022 includes a lead screw 20221 and a rotating wheel 20222, the lead screw 20221 is rotatably connected in the inner cavity of the outer shell 2021, and is located on the same straight line as the first air pipe 2011, the lead screw 20221 is provided with two threads in opposite directions, and the movable blocks 20223 are threadedly sleeved at the two opposite threads, and the two movable blocks 20223 are both rotatable The first transmission rod 20224 is rotatably connected to the two first transmission rods 20224, and the first baffle 20225 is fixedly connected to the second baffle 20226. The first baffle 20225 and the second baffle 20226 correspond to the two second air pipes 2012 one by one. When the first baffle 20225 contacts the outer shell 2021, the second air pipe 2012 connected to the oxygen source is in a closed state with the first air pipe 2011, and the second air pipe 2012 connected to the negative pressure source is in a connected state with the first air pipe 2011. When the second baffle 202226 contacts the outer shell 2021, the second air pipe 2012 connected to the oxygen source is in a closed state with the first air pipe 2011. Tube 2012 is in a connected state with the first air pipe 2011, and the second air pipe 2012 connected to the negative pressure source is in a closed state with the first air pipe 2011. The top end of the lead screw 20221 passes through the outer shell 2021 and is fixed to the rotating wheel 20222.

[0046] Working principle of this embodiment: when in use, the end of the fiberoptic bronchoscope 1 is placed into the patient's body, wherein the two second tracheas 2012 are connected to oxygen and negative pressure respectively. When it is needed to be used as an ordinary fiberoptic bronchoscope, the operator holds the rotating wheel 20222 and rotates it, so that the screw 20221 rotates and the two movable blocks 20223 move toward the two ends of the screw 20221 until the first baffle 20225 blocks the second trachea 2012 connected to oxygen, and the second baffle 20226 moves with the movement of the first baffle 20225, so that the second trachea 2012 connected to the negative pressure source is connected to the first trachea, that is, It can be used; when it is necessary to insert the bronchoscope 1 into the intestine or stomach, it can be rotated in the opposite direction according to the above method. The first baffle 20225 is no longer in contact with the outer shell 2021, and the second baffle 20226 moves until it is in contact with the outer shell 2021, so that the second trachea 2012 connected to oxygen is connected to the first trachea 2011, and then the intestine or stomach can be opened by introducing oxygen for observation. When it is necessary to insert a hemostatic guide wire, after introducing oxygen, control the oxygen inflow speed so that the inflow speed and the outflow speed through the guide wire placement tube 103 are balanced, and then the hemostatic guide wire is inserted through the guide wire placement tube 103.
