Description

Tracheal catheter forceps

Technical Field

The invention relates to a medical instrument, in particular to tracheal catheter forceps.

Background

The endotracheal tube needs to be inserted from the mouth, but the mouth and the trachea have a certain depth and physiological flexibility, so the endotracheal tube is usually delivered into the trachea by using a catheter clamp clinically. In the using process, when the catheter is inserted into the trachea, the throat of a patient can secrete a large amount of secretion, so that the ventilation function of the patient is easily influenced; meanwhile, in the process of inserting foreign matters, a human body can resist and even vomit, and part of vomit can stay at the glottis and other parts, so that the inhalation and the trachea blockage are easily caused. Meanwhile, because the tracheal cannula belongs to invasive operation, mechanical damage can be caused to respiratory mucosa of a patient, and if the patient has strong resistance, the conventional catheter forceps are easy to scrape the inner wall of the oral cavity/throat part to cause secondary damage; in addition, the conventional tracheal catheter forceps have too single function, only have the function of holding and delivering the catheter, cannot realize other functions, and are inconvenient to operate and prone to deviation when the tracheal catheter forceps are operated to hold the catheter to deliver the catheter, so that the intubation failure is caused.
