Cricothyroid membrane incision device

Abstract

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.

Description

technical field [0001] The invention belongs to a medical device, and relates to a novel cricothyroidotomy device for performing cricothyroidotomy during first aid. Defects such as extended time caused by switching and unclear surgical field. Background technique [0002] Cricothyroidotomy or incision is a commonly used emergency technique in various clinical departments. Acute head and neck or throat trauma, laryngeal edema, acute epiglottitis or edema in the pre-epiglottic space, and head and neck tumors caused by various war traumas are likely to cause acute laryngeal obstruction. Caused the patient to suffocate to death. In emergency treatment, tracheotomy and endotracheal intubation are often required. However, for the wounded or patients who are unconditional for tracheal intubation and tracheotomy in an emergency situation, cricothyroid membrane puncture or incision should be performed urgently, the purpose of which is to temporarily establish an artificial respira...

AI Technical Summary

Problems solved by technology

[0003] However, although the technique of cricothyroidotomy has been widely used, and the process seems to be simple and fast, the specific operation process is more complicated, the technical requirements are high, and it must be completed within a certain period of time, especially it needs to be performed by a specialist physician. Therefore, it is easy to delay the time, miss the best time to rescue, and cause the patient's life to be in danger.

The most important thing is that after the cricothyroid membrane is cut, there will be some bleeding in the surgical area, and the incision is small due to anatomical factors, and the incision is often unclear during intubation. After incision, the skin incision for intubation is not easy to find. Problems such as replacement of retractors and retractors have seriously affected the time for the endotracheal intubation to enter the airway and provide ventilation for patients, resulting in prolonged operation time and reducing the success rate of the operation to a certain extent. In emergency situations, especially in battlefield conditions , it is easy to cause the death of the wounded or the patient due to the inability to establish ventilation in time
