[0023] The utility model provides the following technical solutions: a tracheal opening device, during use, a puncture needle directly penetrates the skin, subcutaneous tissue, fascia and other structures, penetrates the tracheal cartilage, and then uses a skin-breaking knife to break the skin, and finally pushes the dilator tube into the trachea, thereby achieving tracheal opening, saving the step of tracheotomy, saving time, reducing the difficulty of operation for the operator, and allowing medical staff to get started faster.

[0024] See also Figure 1-Figure 3 , a tracheal opening device of this embodiment, the main body of which includes a puncture needle 100 and a negative pressure kit 200;

[0025] One end of the puncture needle 100 is connected to a push handle 101, and an interface 102 is provided in the middle of the push handle 101. The puncture needle 100 is driven to penetrate the skin and reach the trachea directly by pushing the push handle 101. A skin-breaking knife 110 is connected to the puncture needle 100 near the needle head, and a push handle 2 111 is connected to the top end of the skin-breaking knife 110. An easy-tear seam 120 is provided on the skin-breaking knife 110. The skin-breaking knife 110 is driven to cut the skin by pushing the push handle 2 111. After the skin is cut, the skin-breaking knife 110 is removed from the puncture needle 100 through the easy-tear seam 120. The skin-breaking knife 110 on the puncture needle 100 is An expansion tube 130 is connected at the top, and a push handle 3 131 is connected to one end of the expansion tube 130. By pushing the push handle 3 131, the expansion tube 130 is driven to enter the trachea through the wound cut by the skin knife 110. The negative pressure kit 200 includes a negative pressure balloon 220, and a negative pressure pipeline 210 is connected to the bottom of the negative pressure balloon 220. A connector matching the interface 102 is provided at the bottom of the negative pressure pipeline 210. The negative pressure kit 200 is connected to the tail end of the puncture needle 100 through the connection between the connector and the interface 102. Whether the puncture needle 100 reaches the trachea is determined by whether the negative pressure balloon 220 changes.

[0026] Combination Figure 1-Figure 3, a tracheal opening device of the present embodiment has the following specific working principle. When using the device, first, push the push handle 101 to drive the puncture needle 100 to penetrate the skin. After entering the skin, confirm whether the tail is leaking. If there is no leakage, install the negative pressure kit 200, and it is necessary to evacuate the air inside it first, and then install it at the tail of the puncture needle 100. Because the interior is airtight and negative pressure at this time, once the trachea is punctured, the balloon will deflate. After deflation, it can be found that the puncture needle 100 has reached the target, and then push the push handle 2 111 to drive the skin-breaking knife 110 forward, and use the straight-shaped blade to cut the skin and enter the trachea. After entering the trachea, push the blade back, remove the skin-breaking knife 110 from the puncture needle 100 through the easy-tear seam 120, and then push the expansion tube 130 into the trachea from the wound opened by the skin-breaking knife 110 by pushing the push handle 3 131 to achieve tracheal opening.
