Suction cup airway foreign body extractor

Abstract

The invention relates to a sucker-like air way foreign matter extractor which comprises a catheter. A connector used for being connected with an injector or a negative pressure suction device is arranged at the head end of the catheter. A sucker-like film made of a transparent or semi-transparent material is arranged at the tail end of the catheter. The sucker-like film is composed of a film disc and a connecting tube. One or more folds with the diameter slightly smaller than that of the connecting pipe are arranged between the film disc and the connecting pipe. The extractor can be used for conveniently sucking and extracting some air way foreign matter difficult to take out, operation time of air way foreign matter extracting surgery is shortened, and the extractor has the advantages of being simple in structure, easy and convenient to operate, small in operation difficulty, high in practicality and the like.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sucker-shaped airway foreign body extractor. Background technique [0002] At present, there are two main methods for taking out foreign bodies in the trachea and bronchus: one is to rely on bronchoscope biopsy forceps, rat bite forceps, and crocodile forceps to clamp foreign bodies and take them out. This method has the following problems: ① Some foreign bodies have a smooth surface and are difficult to clamp, such as smooth bony foreign bodies or beads. ② Some foreign objects are easy to be crushed, and cannot be taken out at one time with clamps. Multiple clamps are required, which takes a long time. And after crushing, some small fragments can enter smaller airways. Such as peanuts. ③ Some foreign bodies that have been in the airway for a long time will stimulate the granulation of the tracheal wall to enclose the surrounding surface of the foreign body. It is necessary to...

AI Technical Summary

Problems solved by technology

This method has the following problems: ① Some foreign bodies have a smooth surface and are difficult to clamp, such as smooth bony foreign bodies or beads

② Some foreign objects are easy to be crushed, and cannot be taken out at one time with clamps. Multiple clamps are required, which takes a long time

④ Some foreign bodies require a long operation time

This method has the following problems: ① The gap between the larger foreign body and the tracheobronchial wall is too small, and the basket-shaped foreign body forceps cannot be fully opened to catch the foreign body

③ It is difficult to remove some foreign bodies and requires a long operation time

④ It is difficult to take some foreign bodies

⑤ The basket-shaped foreign body forceps is composed of four steel wires, the gap between the steel wires is large, the foreign body is not fixed well, and it is easy to fall off when the foreign body is pulled out of the airway with a bronchoscope

Because the shape of the sour plum is nearly round and similar to that of the trachea, the gap between the sour plum and the tracheal wall after entering the trachea is too small, and the basket-shaped foreign body forceps cannot be opened to catch the sour plum

And the appearance of sour plum is thick and soft sour plum meat. When using crocodile forceps and biopsy forceps, the force point is too small to take out the whole sour plum, but only a small piece of sour plum can be clamped Meat

After repeated clamping for many times in this way, we can take advantage of the narrowed gap between the sour plum and the enlarged tracheal wall, and use the basket-shaped foreign body forceps to take out the sour plum. The whole operation takes a long time, and the patient is severely hypoxic and extremely thrilling

[0004] In general, the current methods for removing foreign bodies in the airway through bronchoscopy are limited, and some foreign bodies may not be removed through bronchoscopy and require surgical treatment
