Cricothyroid membrane incision device

The invention discloses a cricothyroid membrane incision device. An incision device and a pull hook device form a whole; the incision of the skin, aponeurosis and cricothyroid membranes can be fast and effectively performed in the operation in one step; the pull hook device is directly put into a cut through pushing a push button and is sufficiently exposed for providing the adverse conditions for trachea cannula in a next step; the use and the operation are convenient and fast; the patient anoxia or even death due to trachea cannula delay caused by reasons of unclear cut exposure, scalpel and pull hook switching and the like is obviously reduced; and the success ratio of the cricothyroid membrane incision and trachea cannula operation is obviously improved.
