Abstract:
Objective To investigate the development and application of a simple one-time cricothyroid membrane fast trocar.Methods The cricothyroid membrane puncture ventilation device can be divided into two parts.Respectively was the casing column stabber parts,parts of the cutter head was an isosceles triangle,the column part slightly flat column arc,the rear end was provided with a cylindrical handle,it was also casing inner core.The second was casing parts.Corresponding for columnar needle knife,the rear end of the sleeve had a cylindrical breathing tube interface,can be connected with the breathing bag or ventilator breathing.Material thyrocricoid puncture sleeve was ABS engineering plastic,the first trial was made of three D printer technology.After technology finished the plastic injection machine or machine production were used to make it.Using this instrument 6 healthy dogs were in the cricothyroid membrane puncture.Respectively after operation with 2 days,4 days,7 days,drug treatment did not be taken during this period after they were observed after 6-12 months.Results 6 dogs were thyrocricocentesis cannulation success only once,with no infection.For 6-12 months after extubation,the dogs bark and systemic activity were normal,no abnormal shortness of breath,breathing difficulties and complications were taken placed.Conclusion The research and production of this instrument has been successful,through animal experiments illustrate the use of this device is safe and effective.It has the advantages of convenient operation and no complications.
