Embodiment 1

[0038] see figure 1 In this embodiment, an adjustable trachea model is provided, including a main airway 101, and a left main bronchus 102 and a right main bronchus 103 respectively connected to the same end of the main airway 101, wherein the main airway 101, The left main bronchus 102 and the right main bronchus 103 are empty tubes respectively, and communicate with each other, and the left main bronchus 102 and the right main bronchus 103 are respectively provided with a left marker 104 and a right marker 105, and the left marker 104 and The distance of the right marker 105 relative to the main airway 101 is adjustable, and the left marker 104 and the right marker 105 are respectively used to identify the positions of the openings of the left upper lobe bronchus and the right upper lobe bronchus. In this embodiment, the main airway 101 represents the main airway 101 of the human body, the left main bronchus 102 and the right main bronchus 103 respectively represent the left...

Embodiment 2

[0059] The main difference between this embodiment 2 and the above-mentioned embodiment 1 is that in the trachea model provided by this embodiment, the left main bronchus 102 and the right main bronchus 103 are respectively provided with external threads 206, and the left identification part 104 and the right The identification parts 105 are respectively provided with internal threads adapted to the external threads 206. The left identification part 104 and the right identification part 105 form a moving pair with the left main bronchus 102 and the right main bronchus 103 respectively, and the internal thread and the external thread 206 The cooperation of the left marker 104 and the right marker 105 can move along the length direction of the left main bronchus 102 and the right main bronchus 103 respectively, thereby realizing the adjustment of the positions of the left marker 104 and the right marker 105.

[0060] As an example, such as Figure 5 As shown, the left marker 104...

Embodiment 3

[0062] The main difference between this embodiment 3 and the above-mentioned embodiment 1 is that in the trachea model provided by this embodiment, such as Figure 6 As shown, several insertion holes 205 are respectively provided along the length direction of the left main bronchus 102 and the right main bronchus 103 , and the left identification part 104 and the right identification part 105 are detachably inserted into the insertion holes 205 respectively. When it is necessary to change the position of the left identification part 104 and the right identification part 105, the medical personnel only need to pull out the left identification part 104 and the right identification part 105 from the jack 205, and then insert them into the jack 205 at a suitable distance, so as to accurately Mark the position of the bronchus opening of the left upper lobe of the patient and the opening of the bronchus of the right upper lobe of the patient, so as to facilitate the selection of the ...

Abstract

The invention relates to an adjustable tracheal model. The model comprises a main airway, a left main bronchus and a right main bronchus; the left main bronchus and the right main bronchus are connected with the same end of the main airway separately and provided with a left marker and a right marker respectively, the distance between the left marker and the right marker relative to the main airway is adjustable, and the left marker and the right marker are used for marking the positions of a left lung upper lobe bronchus opening and a right lung upper lobe bronchus opening respectively. The tracheal model is simple and compact in structure and convenient to use, the positions of the left lung upper lobe bronchus and the right lung upper lobe bronchus can be accurately adjusted according to a CT three-dimensional reconstructed image, a double-lumen bronchus catheter of a suitable type is selected for a patient by utilizing the adjusted model, the purpose of selecting the type of the double-lumen bronchus catheter can be effectively achieved, intubation and alignment on the model can be simulated, the success rate of aligning the double-lumen bronchus catheter can be increased, tracheal injuries can be avoided, the waste of the double-lumen bronchus catheter can also be avoided, and the anesthesia cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable trachea model. Background technique [0002] The double-lumen bronchial catheter is one of the endotracheal catheters, which is used for bronchial intubation; its feature is that it can separate the left and right lungs to achieve double lung isolation, and it is a thoracic operation (lung, esophagus, etc.) to achieve single-lung ventilation. The main tool to provide better surgical conditions, it can be used for ventilation through both sides of the lumen, or only the uninjured side of the lumen, and can suck the secretions separately at any time. It is a necessary consumable for lung abscess and tuberculosis surgery. [0003] At present, the commonly used double-lumen bronchial tubes are divided into left double-lumen tube and right double-lumen tube. Among them, the left double-lumen tube is the Carlen tube, which is a tube that enters the left main bronc...
